Aren't you a forensic? What brings you to our squad? What's your connections to the Raw Diamond case?
![0:25](/images/qVVhBGT0K7Y/0_25.webp)
None. Then why'd you show up at the trading spot?
![0:34](/images/qVVhBGT0K7Y/0_34.webp)
Answer me! Why did you come here?
![2:20](/images/qVVhBGT0K7Y/2_20.webp)
Not just me. Anyone here, and even anyone Lanzi might have met after she left,
![2:26](/images/qVVhBGT0K7Y/2_26.webp)
could be the killer. We're gonna check
![2:32](/images/qVVhBGT0K7Y/2_32.webp)
every suspect. But right now, you're our prime suspect.
![2:41](/images/qVVhBGT0K7Y/2_41.webp)
In the autopsy report, was there any erosive bleeding?
![2:52](/images/qVVhBGT0K7Y/2_52.webp)
Or any foreign objects in Lanzi's stomach?
![2:58](/images/qVVhBGT0K7Y/2_58.webp)
Please go ahead. You've got a person dead from cyanide poisoning,
![3:03](/images/qVVhBGT0K7Y/3_03.webp)
but you can't figure out when or where the poison got slipped to her?
![3:09](/images/qVVhBGT0K7Y/3_09.webp)
It means the poison was already in her body.
![3:16](/images/qVVhBGT0K7Y/3_16.webp)
You mean there's no killer? Qiu Lanzi poisoned and killed herself?
![3:25](/images/qVVhBGT0K7Y/3_25.webp)
You found my fingerprints on that bottle of water. But it's because
![3:30](/images/qVVhBGT0K7Y/3_30.webp)
that one wasn't for Lanzi.
![3:36](/images/qVVhBGT0K7Y/3_36.webp)
Ms. Zhu! Ms. Zhu, what did Mr. Qi say? He thinks the cyanide
![3:42](/images/qVVhBGT0K7Y/3_42.webp)
was already in Qiu Lanzi's body. How did he know? The report was turned in just now.
![3:50](/images/qVVhBGT0K7Y/3_50.webp)
Have you heard of remote case-solving? It's to find out the truth by analyzing crime scenes
![3:55](/images/qVVhBGT0K7Y/3_55.webp)
and examining bodies without physical presence. Only a few forensic doctors can do this,
![4:00](/images/qVVhBGT0K7Y/4_00.webp)
and Qi Sizhe is one of them.
![4:06](/images/qVVhBGT0K7Y/4_06.webp)
Gao Yuan. Check the stuff he used in the lab. Then compare them with that bottle of water.
![4:12](/images/qVVhBGT0K7Y/4_12.webp)
Okay. I go with you.
![4:20](/images/qVVhBGT0K7Y/4_20.webp)
Did you transfer here because of what happened before?
![4:27](/images/qVVhBGT0K7Y/4_27.webp)
You followed Jiang Fei, went to the bar, and visited Li Yiqi in the hospital.
![4:33](/images/qVVhBGT0K7Y/4_33.webp)
What do you wanna do? I've told you. That's not truth.
![4:45](/images/qVVhBGT0K7Y/4_45.webp)
Han Feng. You really think I'd kill a forensic intern
![4:51](/images/qVVhBGT0K7Y/4_51.webp)
I just met?
![4:57](/images/qVVhBGT0K7Y/4_57.webp)
You know very well it couldn't be me. What I think matters not.
![5:02](/images/qVVhBGT0K7Y/5_02.webp)
Figuring out the truth matters.
![5:22](/images/qVVhBGT0K7Y/5_22.webp)
Since he's helping with the case, maybe you could clue him in on some of the stuff we've dug up,
![5:29](/images/qVVhBGT0K7Y/5_29.webp)
just enough to speed things along and catch the killer faster.
![5:36](/images/qVVhBGT0K7Y/5_36.webp)
Okay. Mr. Gao. Please test Mr. Qi's water
![5:42](/images/qVVhBGT0K7Y/5_42.webp)
and effervescent tablets. Tell us what you find out. Okay. Thank you.
![6:03](/images/qVVhBGT0K7Y/6_03.webp)
Mr. Han. Ms. Zhu. The results come out. The report shows each of their saliva
![6:08](/images/qVVhBGT0K7Y/6_08.webp)
in the other's water. So Qiu Lanzi took his water by mistake.
![6:13](/images/qVVhBGT0K7Y/6_13.webp)
Yes. The water Lanzi drank should be Mr. Qi's soda water. And in Mr. Qi's bag
![6:19](/images/qVVhBGT0K7Y/6_19.webp)
was just mineral water. Okay.
![6:25](/images/qVVhBGT0K7Y/6_25.webp)
Gotta go.
![6:33](/images/qVVhBGT0K7Y/6_33.webp)
Mr. Han. Ms. Zhu.
![6:42](/images/qVVhBGT0K7Y/6_42.webp)
I've sure you've known why my fingerprints were on that bottle of water.
![6:49](/images/qVVhBGT0K7Y/6_49.webp)
I wanna know why you said the cyanide was already in Qiu Lanzi's body.
![6:55](/images/qVVhBGT0K7Y/6_55.webp)
I think Lanzi was usually on meds.
![7:01](/images/qVVhBGT0K7Y/7_01.webp)
We did find some stomach meds in her bag. What meds? Omeprazole.
![7:07](/images/qVVhBGT0K7Y/7_07.webp)
What else did the autopsy find? Found two drug capsules in her stomach. The shells looked melted,
![7:13](/images/qVVhBGT0K7Y/7_13.webp)
and one of them had cracked open. Last question.
![7:20](/images/qVVhBGT0K7Y/7_20.webp)
How many pills are left in her medicine bottle? Just one.
![7:39](/images/qVVhBGT0K7Y/7_39.webp)
I think I know how Lanzi was murdered. Lanzi's stomach med, omeprazole, is an enteric-coated capsule.
![7:46](/images/qVVhBGT0K7Y/7_46.webp)
It's designed to pass through the stomach without breaking down in the acid, then get absorbed
![7:52](/images/qVVhBGT0K7Y/7_52.webp)
in the intestines where things are more alkaline. However, it was found in her stomach.
![7:59](/images/qVVhBGT0K7Y/7_59.webp)
Why? Qiu Lanzi took your water by mistake. It was soda water,
![8:05](/images/qVVhBGT0K7Y/8_05.webp)
making the capsule dissolve quicker. The coating on the capsules is slow-release,
![8:10](/images/qVVhBGT0K7Y/8_10.webp)
so they should start working within 4 to 12 hours. But she drank soda, and that cut the time
![8:16](/images/qVVhBGT0K7Y/8_16.webp)
way short. So the cyanide was hidden in Lanzi's stomach med capsules.
![8:24](/images/qVVhBGT0K7Y/8_24.webp)
One of the two capsules in her stomach had cracked open.
![8:29](/images/qVVhBGT0K7Y/8_29.webp)
The killer must've noticed it too when slipping cyanide into the capsules. Once the capsule coating
![8:35](/images/qVVhBGT0K7Y/8_35.webp)
gets partly dissolved by the soda, the cyanide inside comes into contact with the stomach lining.
![8:41](/images/qVVhBGT0K7Y/8_41.webp)
The corrosive poison will definitely cause erosive bleeding in there.
![8:48](/images/qVVhBGT0K7Y/8_48.webp)
How to prove it? There's still one pill left in her medicine bottle.
![8:55](/images/qVVhBGT0K7Y/8_55.webp)
Su.
![9:09](/images/qVVhBGT0K7Y/9_09.webp)
I'm sorry, Ms. Zhao. The cooperation with He City is about to end, and you're going abroad. Sorry we have to call you back.
![9:14](/images/qVVhBGT0K7Y/9_14.webp)
It's fine. I'll be there if you need me. So what happened? What do you want me to check?
![9:22](/images/qVVhBGT0K7Y/9_22.webp)
Mr. Qi figured the victim might take omeprazole capsules laced with cyanide, but then drank soda by accident.
![9:27](/images/qVVhBGT0K7Y/9_27.webp)
That made the capsule dissolve in the stomach instead of the intestines. We've found the capsules in her stomach.
![9:34](/images/qVVhBGT0K7Y/9_34.webp)
So we need you here to test one last pill in the victim's medicine bottle.
![9:41](/images/qVVhBGT0K7Y/9_41.webp)
I got this. Thank you.
![10:13](/images/qVVhBGT0K7Y/10_13.webp)
How is it? Ms. Zhao is testing the pill. It needs some time.
![10:20](/images/qVVhBGT0K7Y/10_20.webp)
Cross-check all the evidence and don't miss any details. I'll wait here. Okay.
![10:34](/images/qVVhBGT0K7Y/10_34.webp)
The dosage of omeprazole is three pills a day, one in the morning and two in the evening.
![10:40](/images/qVVhBGT0K7Y/10_40.webp)
If the killer wanted to make sure Lanzi died that very night, he must've made certain
![10:46](/images/qVVhBGT0K7Y/10_46.webp)
at least one of the two pills she took was poisoned.
![10:52](/images/qVVhBGT0K7Y/10_52.webp)
If he only poisoned one pill, Lanzi might not take it until the second morning.
![10:57](/images/qVVhBGT0K7Y/10_57.webp)
That's a one-in-three chance. But if he poisoned three pills, then there'd always be
![11:03](/images/qVVhBGT0K7Y/11_03.webp)
one poisoned pill left as evidence. So, poisoning exactly
![11:10](/images/qVVhBGT0K7Y/11_10.webp)
two pills was the sweet spot. But if Qiu Lanzi
![11:16](/images/qVVhBGT0K7Y/11_16.webp)
took both the poisoned ones, we couldn't find anything in the left one as evidence.
![11:21](/images/qVVhBGT0K7Y/11_21.webp)
She's got a one-in-three chance of swallowing both poisoned pills, which means
![11:27](/images/qVVhBGT0K7Y/11_27.webp)
the killer only has that same shot at not leaving evidence in the medicine.
![11:33](/images/qVVhBGT0K7Y/11_33.webp)
So we're just gambling on the last one.
![11:47](/images/qVVhBGT0K7Y/11_47.webp)
We've got the result. The pill indeed contains cyanide, same as Mr. Qi supposed.
![12:04](/images/qVVhBGT0K7Y/12_04.webp)
Mr. Qi, you're off the hook for now. You can go.
![12:12](/images/qVVhBGT0K7Y/12_12.webp)
Ms. Zhu. I wanna help with the case and find out Lanzi's murderer.
![12:17](/images/qVVhBGT0K7Y/12_17.webp)
And, something's off with Jiang Fei's autopsy report.
![12:24](/images/qVVhBGT0K7Y/12_24.webp)
I'm afraid you gotta stay outta Jiang Fei and Qiu Lanzi's case.
![12:32](/images/qVVhBGT0K7Y/12_32.webp)
I wanna see Jiang Fei's autopsy report. You're not the only forensic here. You don't gotta handle every single case.
![13:02](/images/qVVhBGT0K7Y/13_02.webp)
Come in. Mr. Bai.
![13:12](/images/qVVhBGT0K7Y/13_12.webp)
Qi Sizhe is off the hook now? Yes. And he found out how Qiu Lanzi died?
![13:22](/images/qVVhBGT0K7Y/13_22.webp)
Qi Sizhe is a brilliant forensic doctor. And he's quite reasonable.
![13:28](/images/qVVhBGT0K7Y/13_28.webp)
So he won't blame you for the necessity of your interrogation of him.
![13:36](/images/qVVhBGT0K7Y/13_36.webp)
Mr. Bai. Do you know about his past?
![13:43](/images/qVVhBGT0K7Y/13_43.webp)
He had a severe car accident. And I thought we'd lose a talented forensic doctor.
![13:49](/images/qVVhBGT0K7Y/13_49.webp)
But I never thought he'd manage to hit rehab milestones in just a year that usually
![13:54](/images/qVVhBGT0K7Y/13_54.webp)
take others three to five years. You can imagine how much this position means to him.
![14:03](/images/qVVhBGT0K7Y/14_03.webp)
But he's quite stubborn. So is Han Feng. Among you three,
![14:10](/images/qVVhBGT0K7Y/14_10.webp)
you're the calmest and most rational one. So I hope you can get them together
![14:15](/images/qVVhBGT0K7Y/14_15.webp)
and handle cases.
![14:26](/images/qVVhBGT0K7Y/14_26.webp)
Where's Xi? I had her check 788 Bar's security footage. I still have some doubts.
![14:32](/images/qVVhBGT0K7Y/14_32.webp)
We found the cyanide in Qiu Lanzi's stomach meds. The killer could
![14:38](/images/qVVhBGT0K7Y/14_38.webp)
get close to her and switch her meds. So it could be someone she knew all along.
![14:46](/images/qVVhBGT0K7Y/14_46.webp)
Qiu Lanzi said something was off with Jiang Fei's body. Ask Mr. Gao to check his autopsy report again.
![14:54](/images/qVVhBGT0K7Y/14_54.webp)
Su. Dig deeper into the social circles around Qiu Lanzi, Jiang Fei, and Li Yiqi,
![14:59](/images/qVVhBGT0K7Y/14_59.webp)
especially Qiu Lanzi's connections. Okay. Mr. Han. Anything to add?
![15:05](/images/qVVhBGT0K7Y/15_05.webp)
Nothing, for now.
![16:05](/images/qVVhBGT0K7Y/16_05.webp)
Xi, got anything? Yeah. Half a month before Li Yiqi's case,
![16:10](/images/qVVhBGT0K7Y/16_10.webp)
Mr. Qi showed up at 788 Bar quite a few times. I cross-checked a few security footages. Every time Mr. Qi showed up,
![16:16](/images/qVVhBGT0K7Y/16_16.webp)
Jiang Fei was there too. Looks like Mr. Qi was following Jiang Fei.
![16:35](/images/qVVhBGT0K7Y/16_35.webp)
Ms. Zhu. Here's Qi Sizhe's info. He had a severe
![16:41](/images/qVVhBGT0K7Y/16_41.webp)
accident two years ago. A woman riding in his car died on the spot.
![16:49](/images/qVVhBGT0K7Y/16_49.webp)
Ms. Zhu. Anything wrong with him? Get back to work. Yes.
![18:24](/images/qVVhBGT0K7Y/18_24.webp)
Why did you come? Why did you follow Li Yiqi and Jiang Fei?
![18:40](/images/qVVhBGT0K7Y/18_40.webp)
You know why. 'Cause it's related to Fei's death.
![18:47](/images/qVVhBGT0K7Y/18_47.webp)
Raw Diamond...
![18:57](/images/qVVhBGT0K7Y/18_57.webp)
You came for the Raw Diamond case. Jiang Fei's death isn't an accident.
![19:05](/images/qVVhBGT0K7Y/19_05.webp)
It's a murder.
![19:14](/images/qVVhBGT0K7Y/19_14.webp)
His body was found at 11:30 or so in the morning. It's the same as room temperature,
![19:20](/images/qVVhBGT0K7Y/19_20.webp)
22 degrees. He's got these little square marks on his chest, bright red.
![19:25](/images/qVVhBGT0K7Y/19_25.webp)
And the lividity on the side of the body is all patchy, dark red. Any problems? The bright red lividity
![19:30](/images/qVVhBGT0K7Y/19_30.webp)
doesn't match the estimated time of death, and the body's cooling rate is way off. There are two possibilities.
![19:36](/images/qVVhBGT0K7Y/19_36.webp)
First, the killer was trying to mess with the time of death. Second, the way the murder was done
![19:43](/images/qVVhBGT0K7Y/19_43.webp)
messed with the body's temperature. And I think the second one's way more likely.
![19:49](/images/qVVhBGT0K7Y/19_49.webp)
So my guess is, Jiang Fei probably... Froze to death?
![19:54](/images/qVVhBGT0K7Y/19_54.webp)
At his own home? But his place doesn't have such an environment. There is one.
![20:09](/images/qVVhBGT0K7Y/20_09.webp)
No way. It's too small.
![20:16](/images/qVVhBGT0K7Y/20_16.webp)
If the killer stuffed Jiang Fei into the fridge, there gotta be
![20:21](/images/qVVhBGT0K7Y/20_21.webp)
a lot of scratches and marks on Jiang Fei's body. But so far, there aren't any
![20:27](/images/qVVhBGT0K7Y/20_27.webp)
such marks on the body. Only lividity. Lividity is the marks formed by blood
![20:33](/images/qVVhBGT0K7Y/20_33.webp)
due to gravity at the dripping points. Jiang Fei was lying on his side when he died.
![20:38](/images/qVVhBGT0K7Y/20_38.webp)
So, the lividity should only have formed on the side. But look here.
![20:45](/images/qVVhBGT0K7Y/20_45.webp)
There are bright red marks on Jiang Fei's chest. Also, when Jiang Fei died,
![20:51](/images/qVVhBGT0K7Y/20_51.webp)
his clothes were all wrinkled. His clothes look like they got wet and then dried off...
![20:58](/images/qVVhBGT0K7Y/20_58.webp)
His fingers and toes were all wrinkled, a result of prolonged soaking in water
![21:04](/images/qVVhBGT0K7Y/21_04.webp)
and osmosis. Jiang Fei was always a slob, so it's no wonder his clothes were wrinkled.
![21:11](/images/qVVhBGT0K7Y/21_11.webp)
When we found the body, there was water at the bottom of the bathtub. The wrinkles on his skin were probably caused by soaking in the water.
![21:17](/images/qVVhBGT0K7Y/21_17.webp)
Well, going by your logic, his fingers and toes shouldn't have gotten wrinkly since they haven't touched
![21:23](/images/qVVhBGT0K7Y/21_23.webp)
the water at the bottom of the tub. But turns out that's not what happened.
![21:35](/images/qVVhBGT0K7Y/21_35.webp)
So Jiang Fei didn't freeze to death in a freezer, but in the...
![21:40](/images/qVVhBGT0K7Y/21_40.webp)
In the bathtub.
![21:49](/images/qVVhBGT0K7Y/21_49.webp)
The window in Jiang Fei's bathroom has always been open.
![22:13](/images/qVVhBGT0K7Y/22_13.webp)
When the body was found, the ice had already melted, but there were frostbite
![22:18](/images/qVVhBGT0K7Y/22_18.webp)
marks on the body. The bright red mark on his chest is
![22:23](/images/qVVhBGT0K7Y/22_23.webp)
the best proof. This is also caused by the failure of
![22:29](/images/qVVhBGT0K7Y/22_29.webp)
various organs at low temperatures.
![22:34](/images/qVVhBGT0K7Y/22_34.webp)
Judging from the traces at the scene, everything matches what Mr. Qi said.
![22:39](/images/qVVhBGT0K7Y/22_39.webp)
Got it. Han Feng.
![22:45](/images/qVVhBGT0K7Y/22_45.webp)
Are you buying that Jiang Fei's death wasn't an accident but murder now?
![23:02](/images/qVVhBGT0K7Y/23_02.webp)
If Mr. Qi's reasoning holds up, we gotta check this place for any signs of
![23:07](/images/qVVhBGT0K7Y/23_07.webp)
a second person. Search more thoroughly.
![24:07](/images/qVVhBGT0K7Y/24_07.webp)
I wanna learn more from you and become a great forensic doctor like you!
![24:30](/images/qVVhBGT0K7Y/24_30.webp)
Ms. Zhu. Any progress in Jiang Fei's case?
![24:37](/images/qVVhBGT0K7Y/24_37.webp)
You've been cleared of suspicion. So why still look into Jiang Fei? I know you're really concerned about Jiang Fei's case
![24:43](/images/qVVhBGT0K7Y/24_43.webp)
and Li Yiqi's case. I also know you can lead us closer to the truth.
![24:49](/images/qVVhBGT0K7Y/24_49.webp)
But so far, you haven't explained the coincidences of your appearance
![24:55](/images/qVVhBGT0K7Y/24_55.webp)
in these two cases. And this time,
![25:00](/images/qVVhBGT0K7Y/25_00.webp)
why did you go to investigate Jiang Fei alone?
![25:06](/images/qVVhBGT0K7Y/25_06.webp)
I want you to answer my question. And I'm not gonna answer any questions related to this case
![25:12](/images/qVVhBGT0K7Y/25_12.webp)
until I trust you. Ms. Zhu.
![25:18](/images/qVVhBGT0K7Y/25_18.webp)
I'm a forensic doctor. When someone dies, only forensic doctors can tell what they
![25:26](/images/qVVhBGT0K7Y/25_26.webp)
went through before they died. And I believe whoever it is,
![25:33](/images/qVVhBGT0K7Y/25_33.webp)
even drug dealers like Jiang Fei, they all deserve the truth.
![25:39](/images/qVVhBGT0K7Y/25_39.webp)
I saw the possibility of homicide in Jiang Fei's case. So I gotta figure out the truth.
![25:48](/images/qVVhBGT0K7Y/25_48.webp)
But he's quite stubborn. So is Han Feng.
![25:54](/images/qVVhBGT0K7Y/25_54.webp)
So I hope you can get them together and handle cases.
![26:03](/images/qVVhBGT0K7Y/26_03.webp)
So Jiang Fei died a little after 4 am? Yes.
![26:08](/images/qVVhBGT0K7Y/26_08.webp)
If he froze to death, his body temperature was lower than normal. So the time it takes to cool down
![26:13](/images/qVVhBGT0K7Y/26_13.webp)
would be shorter. Mr. Han.
![26:19](/images/qVVhBGT0K7Y/26_19.webp)
Mr. Qi inferred that Jiang Fei froze to death. Let him tell us about it.
![26:33](/images/qVVhBGT0K7Y/26_33.webp)
All we know is that Jiang Fei was frozen to death by the killer, but there aren't any clues
![26:39](/images/qVVhBGT0K7Y/26_39.webp)
to find the killer. The killer made Jiang Fei
![26:45](/images/qVVhBGT0K7Y/26_45.webp)
take cephalosporin when he was drunk, causing a disulfiram-like reaction.
![26:50](/images/qVVhBGT0K7Y/26_50.webp)
Then, when he was unconscious, the killer froze his body with ice, which led to the failure of all his
![26:56](/images/qVVhBGT0K7Y/26_56.webp)
internal organs, especially his heart, and he died. It shows that the killer has some knowledge human physiology.
![27:02](/images/qVVhBGT0K7Y/27_02.webp)
Mr. Gao, after the first autopsy and test, what was in his stomach as food residue?
![27:09](/images/qVVhBGT0K7Y/27_09.webp)
Wine and sausage, no cephalosporin. But the cephalosporin on his table was already opened,
![27:15](/images/qVVhBGT0K7Y/27_15.webp)
and the pharmacological test detected it. The sausage wasn't digested, which means the last thing
![27:22](/images/qVVhBGT0K7Y/27_22.webp)
the victim ate was the sausage.
![27:33](/images/qVVhBGT0K7Y/27_33.webp)
Have you found a knife there? No. There are cuts on the sausage
![27:39](/images/qVVhBGT0K7Y/27_39.webp)
but no knife around. Could someone have taken it? Jiang Fei's body didn't have
![27:45](/images/qVVhBGT0K7Y/27_45.webp)
a scratch on it. The knife couldn't be the murder weapon. So why'd the killer take it away?
![27:52](/images/qVVhBGT0K7Y/27_52.webp)
Did you guys do luminol at the scene?
![28:02](/images/qVVhBGT0K7Y/28_02.webp)
There are no cuts on the body, but the killer had to take the knife from the scene.
![28:07](/images/qVVhBGT0K7Y/28_07.webp)
That means... The knife wasn't used on the victim. But on the killer.
![28:48](/images/qVVhBGT0K7Y/28_48.webp)
If this isn't Jiang Fei's blood, then it gotta be the killer's.
![29:01](/images/qVVhBGT0K7Y/29_01.webp)
Why didn't you ask Mr. Qi to do the bloodstain comparison?
![29:06](/images/qVVhBGT0K7Y/29_06.webp)
The results are out. No records matching in the database. Thank you.
![29:24](/images/qVVhBGT0K7Y/29_24.webp)
So here's the timeline of these cases. On the evening of the 7th, Qiu Lanzi joined us investigating
![29:29](/images/qVVhBGT0K7Y/29_29.webp)
the 788 Bar assault case. Then she teamed up with Mr. Gao and Mr. Qi
![29:35](/images/qVVhBGT0K7Y/29_35.webp)
for the Li Yiqi's blood sample analysis until the next day. We found Jiang Fei's body at noon the next day,
![29:42](/images/qVVhBGT0K7Y/29_42.webp)
and Qiu Lanzi showed up later. That night, she, Mr. Qi and Mr. Gao dissected Jiang Fei's body.
![29:49](/images/qVVhBGT0K7Y/29_49.webp)
We found the remains of stomach meds in Qiu Lanzi's stomach. Based on the dissolution rate of the meds
![29:55](/images/qVVhBGT0K7Y/29_55.webp)
and the timeline, Qiu Lanzi should've taken the stomach meds between the time
![30:00](/images/qVVhBGT0K7Y/30_00.webp)
after the dissection of Jiang Fei's body and her death. The first time Qiu Lanzi left the station
![30:06](/images/qVVhBGT0K7Y/30_06.webp)
and met me was around 9 pm. Two hours later, I got a call from Qiu Lanzi.
![30:12](/images/qVVhBGT0K7Y/30_12.webp)
She said she'd found a lead on Jiang Fei's body. Ten minutes later, when Mr. Han and I got to the forensic office,
![30:19](/images/qVVhBGT0K7Y/30_19.webp)
we found her body. The stomach medicine was found among her belongings.
![30:24](/images/qVVhBGT0K7Y/30_24.webp)
She usually kept her stuff in the locker in the changing room. Got anything from the surveillance over there?
![30:29](/images/qVVhBGT0K7Y/30_29.webp)
No cameras on the floor. There are just people going to and from work there. And Mr. Bai means we shouldn't
![30:35](/images/qVVhBGT0K7Y/30_35.webp)
expand the investigation for now. He wants us to narrow down the suspects first.
![30:46](/images/qVVhBGT0K7Y/30_46.webp)
So the most likely time for Qiu Lanzi to take the pills is between the time
![30:51](/images/qVVhBGT0K7Y/30_51.webp)
she left the station and came back. We just don't know where she went and who she met.
![31:04](/images/qVVhBGT0K7Y/31_04.webp)
What about Jiang Fei? Don't forget Qiu Lanzi said she had info about
![31:10](/images/qVVhBGT0K7Y/31_10.webp)
Jiang Fei's cause of death before she died. Jiang Fei went home after getting drunk.
![31:16](/images/qVVhBGT0K7Y/31_16.webp)
Where did he drink and who did he drink with? Have you found out? He didn't use mobile payment or cards. He always used cash,
![31:22](/images/qVVhBGT0K7Y/31_22.webp)
so it's hard to find his consumption records. People like him are always afraid of leaving any clues.
![31:31](/images/qVVhBGT0K7Y/31_31.webp)
Wan, let's go to the bar to check Jiang Fei's movements before he drank.
![31:36](/images/qVVhBGT0K7Y/31_36.webp)
Xi, go and find out who Qiu Lanzi met after she left the station. Let's split up.
![31:42](/images/qVVhBGT0K7Y/31_42.webp)
Okay. Do as Mr. Han says.
![32:04](/images/qVVhBGT0K7Y/32_04.webp)
It's here, Mr. Han.
![32:10](/images/qVVhBGT0K7Y/32_10.webp)
No, Mr. Han...
![32:46](/images/qVVhBGT0K7Y/32_46.webp)
You're in charge here? This is legit business. Legit business? Then why so serious,
![32:52](/images/qVVhBGT0K7Y/32_52.webp)
needing a guide to find here? Oh, come on! This is a gimmick. More people will wanna come in
![32:58](/images/qVVhBGT0K7Y/32_58.webp)
if they need someone to bring them in. That's smart. Since it's so complicated to get here,
![33:04](/images/qVVhBGT0K7Y/33_04.webp)
you should know who came here the day before yesterday, right? Sir. How the heck can I remember
![33:10](/images/qVVhBGT0K7Y/33_10.webp)
all these guests every day? Take us to the security room. Sir. You need a warrant to do so.
![33:17](/images/qVVhBGT0K7Y/33_17.webp)
A warrant, huh? I'm gonna call my buddies from Public Security Brigade and let them check it out.
![33:28](/images/qVVhBGT0K7Y/33_28.webp)
Sir. You can check whatever you want.
![33:35](/images/qVVhBGT0K7Y/33_35.webp)
We checked Jiang Fei's social circles. Super complicated. He's lived in cities all over the country. A drug dealer like him's gonna
![33:41](/images/qVVhBGT0K7Y/33_41.webp)
have a lot of enemies. If we just look at the motives for murder, there are a bunch of suspects.
![33:46](/images/qVVhBGT0K7Y/33_46.webp)
Here's his hidden ledger we found. There are up to 40 drug addicts listed in it, not to mention those
![33:53](/images/qVVhBGT0K7Y/33_53.webp)
who bought imitation guns, plasma, and illegal drugs. Ms. Zhu. This is Qiu Lanzi's phone.
![33:59](/images/qVVhBGT0K7Y/33_59.webp)
Got anything? I checked Qiu Lanzi's call records. After she left at 9 o'clock,
![34:05](/images/qVVhBGT0K7Y/34_05.webp)
she made four consecutive calls within five minutes, and they were all to the same person. Who?
![34:11](/images/qVVhBGT0K7Y/34_11.webp)
It's a chemical factory's lab. But it was off-work time then, and she called the switchboard,
![34:16](/images/qVVhBGT0K7Y/34_16.webp)
so we still can't find out who she contacted. We gotta find out what relationship this factory has with Qiu Lanzi.
![34:22](/images/qVVhBGT0K7Y/34_22.webp)
Okay. Ms. Zhu. Have you checked Qiu Lanzi's phone?
![34:28](/images/qVVhBGT0K7Y/34_28.webp)
Xi just gave it to me. I watched the videos of Qiu Lanzi before and after she left here. She never stopped checking her phone.
![34:36](/images/qVVhBGT0K7Y/34_36.webp)
I remembered that Mr. Han told me when he saw Qiu Lanzi that day, she was also anxiously checking her phone.
![34:43](/images/qVVhBGT0K7Y/34_43.webp)
There must be some clues on her phone. She just didn't have time to tell us then.
![34:54](/images/qVVhBGT0K7Y/34_54.webp)
Stop. Who's the girl drinking with Jiang Fei?
![35:01](/images/qVVhBGT0K7Y/35_01.webp)
Jiang Fei had introduced her to us. Zhang Lu, I remember. She's into Lolita fashion, close to Jiang Fei.
![35:08](/images/qVVhBGT0K7Y/35_08.webp)
She took photos of Jiang Fei's body? But phones are forbidden in the dissection room...
![35:14](/images/qVVhBGT0K7Y/35_14.webp)
Maybe she had some reason. Check out these last three photos.
![35:20](/images/qVVhBGT0K7Y/35_20.webp)
The first two are of the tattoo on Jiang Fei's arm, one taken without a black light,
![35:26](/images/qVVhBGT0K7Y/35_26.webp)
and the other with a black light. And the last one is of the skin on his wrist.
![35:32](/images/qVVhBGT0K7Y/35_32.webp)
Also, the first two were taken at the same time. But there's a gap of over 20 minutes before the last one.
![35:38](/images/qVVhBGT0K7Y/35_38.webp)
Why did she wait over 20 minutes to take a photo of the skin on the wrist
![35:44](/images/qVVhBGT0K7Y/35_44.webp)
without a black light? What did she find out?
![35:51](/images/qVVhBGT0K7Y/35_51.webp)
I saw some illegal stuff in the bar near Ruixi Building. I just saw it when working.
![35:57](/images/qVVhBGT0K7Y/35_57.webp)
It's fine. You're welcome. Treat me to dinner then.
![36:05](/images/qVVhBGT0K7Y/36_05.webp)
Wan. Thank you. It's nothing.
![36:11](/images/qVVhBGT0K7Y/36_11.webp)
Ms. Zhu asked me to investigate with you. No need to say that.
![36:24](/images/qVVhBGT0K7Y/36_24.webp)
I saw Qiu Lanzi taking those photos, but I just glanced and left.
![36:30](/images/qVVhBGT0K7Y/36_30.webp)
I was in the next room with Ms. Zhao taking samples for toxicology testing. If you also left,
![36:37](/images/qVVhBGT0K7Y/36_37.webp)
then Lanzi was the only one left in the autopsy room. But when she was taking the photos,
![36:45](/images/qVVhBGT0K7Y/36_45.webp)
she asked me what this was. What is this? It should be an old injury
![36:51](/images/qVVhBGT0K7Y/36_51.webp)
or a mark left after having a tattoo removed. No. It seems to be a fluorescent tattoo.
![37:10](/images/qVVhBGT0K7Y/37_10.webp)
There are two photos of the tattoo on the left forearm, one in natural color and the other under a black light.
![37:17](/images/qVVhBGT0K7Y/37_17.webp)
If we follow the logic of the previous two photos, there should be another black-light photo.
![37:28](/images/qVVhBGT0K7Y/37_28.webp)
There are lots of group photos of Jiang Fei with different girls on his phone, and one of them is Zhang Lu, the girl we've been looking for.
![37:35](/images/qVVhBGT0K7Y/37_35.webp)
Zhang Lu, 24 years old, living in Xinhua Road, He City, an intern researcher at an inorganic chemistry institute,
![37:40](/images/qVVhBGT0K7Y/37_40.webp)
majored in chemistry. She knows Qiu Lanzi. They were high school classmates, so they rented an room
![37:46](/images/qVVhBGT0K7Y/37_46.webp)
and were roommates shortly. In the call records we retrieved, the last call Qiu Lanzi made
![37:52](/images/qVVhBGT0K7Y/37_52.webp)
was to Zhang Lu's workplace.
![38:08](/images/qVVhBGT0K7Y/38_08.webp)
You said you saw Zhang Lu and Qiu Lanzi arguing that day, right? Yeah.
![38:15](/images/qVVhBGT0K7Y/38_15.webp)
I did see them arguing. But I didn't catch what they were arguing about.
![38:25](/images/qVVhBGT0K7Y/38_25.webp)
When I left, I saw that girl wasn't feeling well and took some medicine.
![38:32](/images/qVVhBGT0K7Y/38_32.webp)
Are you sure Qiu Lanzi took medicine at that time? I'm sure.
![38:46](/images/qVVhBGT0K7Y/38_46.webp)
Where's Zhang Lu? Mr. Han. We've been searching for her with your info.
![39:00](/images/qVVhBGT0K7Y/39_00.webp)
Excuse me. Your ID card and driving license please. Please open your trunk.
![39:12](/images/qVVhBGT0K7Y/39_12.webp)
You're Zhang Lu, right? Zhang Lu. Please cooperate with us.
![39:34](/images/qVVhBGT0K7Y/39_34.webp)
Zhang Lu, 24 years old. A researcher of the chemistry institute in He City. Were you at the basement bar
![39:41](/images/qVVhBGT0K7Y/39_41.webp)
in Yunjin Building with Jiang Fei on the evening of August 7th? Yeah.
![39:47](/images/qVVhBGT0K7Y/39_47.webp)
Then did you go home with him? No. I just had a few drinks and went back to my own place.
![39:53](/images/qVVhBGT0K7Y/39_53.webp)
Is there anyone who can prove it? Prove it? Why? I live alone.
![39:59](/images/qVVhBGT0K7Y/39_59.webp)
How can there be a witness? So no one can prove you stayed at your own place that night.
![40:09](/images/qVVhBGT0K7Y/40_09.webp)
What was Jiang Fei's state when you saw him for the last time? He...
![40:17](/images/qVVhBGT0K7Y/40_17.webp)
He seemed to catch cold. You're out drinking with a cold?
![40:26](/images/qVVhBGT0K7Y/40_26.webp)
Do you even know that mixing antibiotics with alcohol could kill you?
![40:32](/images/qVVhBGT0K7Y/40_32.webp)
But I just really wanted to have a drink with you.
![40:41](/images/qVVhBGT0K7Y/40_41.webp)
How'd you hurt your finger? Cut it during an experiment.
![40:46](/images/qVVhBGT0K7Y/40_46.webp)
What did Qiu Lanzi say when she came to the lab? What'd she tell you guys?
![40:52](/images/qVVhBGT0K7Y/40_52.webp)
Isn't she interning here? Call her over! I'll confront her! Qiu Lanzi's dead.
![40:59](/images/qVVhBGT0K7Y/40_59.webp)
Did you kill her? Dead... How... How come...
![41:12](/images/qVVhBGT0K7Y/41_12.webp)
Zhang Lu, now we suspect you're the prime suspect in the murder cases of Qiu Lanzi and Jiang Fei. Got anything to say?
![41:20](/images/qVVhBGT0K7Y/41_20.webp)
If Zhang Lu's blood sample matches the one we took from Jiang Fei's place, she's most likely
![41:26](/images/qVVhBGT0K7Y/41_26.webp)
the killer. I didn't! I never killed anyone!
![41:31](/images/qVVhBGT0K7Y/41_31.webp)
I didn't... I really didn't! Then just answer our questions! What did she say to you?
![41:37](/images/qVVhBGT0K7Y/41_37.webp)
She... She told me Jiang Fei was dead,
![41:44](/images/qVVhBGT0K7Y/41_44.webp)
and she saw my name on the body...
![41:59](/images/qVVhBGT0K7Y/41_59.webp)
How is it? Wait a moment.
![42:17](/images/qVVhBGT0K7Y/42_17.webp)
Ms. Zhu. The result is out.
![42:23](/images/qVVhBGT0K7Y/42_23.webp)
Mr. Han. It matches.
![42:30](/images/qVVhBGT0K7Y/42_30.webp)
Su. Arrest her. Xi, untie her. It's her.
![42:36](/images/qVVhBGT0K7Y/42_36.webp)
No... Not me! I didn't kill them! I didn't!
![42:42](/images/qVVhBGT0K7Y/42_42.webp)
It's not me! It's really not me! I never killed anyone! It's not me! I didn't!
![42:47](/images/qVVhBGT0K7Y/42_47.webp)
Don't arrest me! Please! It's not me! You got the wrong person! It's not me! Not me!
![42:52](/images/qVVhBGT0K7Y/42_52.webp)
Really not! I didn't kill them! You got the wrong person! It's not me! Not me!
![43:06](/images/qVVhBGT0K7Y/43_06.webp)
We got the wrong person. It's not her.
![43:33](/images/qVVhBGT0K7Y/43_33.webp)
Raw Diamond case is over! You just can't deal with reality! You never figured out Fei's death!
![43:39](/images/qVVhBGT0K7Y/43_39.webp)
Li Yiqi. Jiang Fei. They're the clue from the case! Hey! Stop!
![43:45](/images/qVVhBGT0K7Y/43_45.webp)
There's an opening here. The kidnapped girl was probably taken inside.
![43:50](/images/qVVhBGT0K7Y/43_50.webp)
The killer set this up to throw us off about the cause of death. He knows way too much about
![43:56](/images/qVVhBGT0K7Y/43_56.webp)
forensic, autopsies, even our police procedures. Wait, are you saying... The killer is one of us?
