Zhang Yunhu and others also discovered Chen Yan's arrival.

But he just nodded his head and was busy watching the survey site.

Because the nature of the case is too bad, it has already reached the provincial team.

The above gave a deadline of one week to solve the case.

Zhang Yunhu is now personally leading the team and is in charge of the Scarlet Cross murder case.

【Ding! The task of the strongest police training system is released. 】

[Detect the Scarlet Cross murder case, within a five-day period, complete the task, reward skills and firearms specialization, and cancel the task reward if it fails or expires. 】

Two beeps sounded in Chen Yan's mind.

The reward this time turned out to be a skill and firearm specialization?

Chen Yan thought that the system would only reward rewards such as the opening of its own genetic lock.

In my opinion, the power of the system has a lot of room for exploration.

"Xiao Chen," Liu Qingshan was also busy with his own task after introducing the general situation: "You should keep an eye on the outside, don't walk around, don't do anything privately, and see how others conduct on-site investigations. ."

Chen Yan nodded: "Master, don't worry, I understand this!"

Although Chen Yan is a trainee police officer, his colleagues in the team have long recognized his ability.

Let alone the online recruiting case, it is a little accidental after all.

But the case of killing his wife with a corpse that was discovered the day before yesterday was a solid ability.

Chen Yan discovered some details that so many veterans in the team had not discovered.

Not only found, but also found the most important evidence.

Otherwise, it would really be classified as a disappearance case. Not only would the murderer go unpunished, but the team would not be able to raise their heads in the future.

However, Chen Yan's current approval for rectification has not yet come down. If he does not rectify for a moment, the rules cannot be broken.

However, this does not matter to Chen Yan.

As soon as he entered the scene, Chen Yan turned on the olfactory gene lock and the visual gene lock.

The strong smell of blood overwhelmed all other scents.

It is obviously impossible to rely on the suspect's body odor to track down the murderer.

Moreover, this is a classroom, and the flow of people is very large. Under the coverage of the **** smell, there are hundreds of body odors, and there is no way to distinguish them.

However, Chen Yan did not gain anything.

Among the countless scents, Chen Yan found two special ones.

One is alcohol, a very high concentration of alcohol.

The other taste is very mild, but very special.

Succinylcholine, also known as scoline, has a similar effect to N2 choline receptor blockers, which is a commonly used muscle relaxant.

However, unlike N2 choline receptor blockers, the main effect of succinylcholine is to relax the limbs and neck muscles. The effect is fast and short-lived, and there are no side effects such as blood pressure drop and bradycardia.

To put it bluntly, it can make the recipient's limbs weak and unable to speak.

This drug is a controlled drug. How could it smell like this in a classroom?

At the same time, Chen Yan's visual gene lock was turned on, and with the hyper-amnesia, everything in Chen Yan's body was like a jigsaw puzzle, magnifying in Chen Yan's mind.

The statement that opens up the perspective of God seems to be above the classroom, overlooking everything.

The bloodstains that were originally messy on the ground now showed a pattern.

Rose!

It turned out to be a pattern of wild roses!

Why did the murderer leave a pattern of briar roses with the blood of the victim?

What is the special meaning?

Is it a mark left by the killer on purpose?

There are also crosses made of the skins of the victims.

Why?

Why is it a cross and not another pattern?

The **** cross made of human skin in his mind instantly enlarged in front of Chen Yan's eyes.

Palms, shoulders, chest, forehead, lower abdomen, thighs, calves, ankles…

A total of 21 steel nails.

Moreover, on the body of the victim, there are also piercing wounds in the corresponding position.

At the same time, the blood between the human skin and the corpse was very continuous, as if the corpse was first nailed to the blackboard, then took off the human skin, and knelt under the human skin.

It is conceivable how much pain the victims endured during this process.

Enlarge the corpse.

The posture of the corpse is very special.

It is impossible for a dead body to naturally present a kneeling posture.

Enlarging the image of the corpse, there are wire clamps on the lower limbs, waist and chest and abdomen of the corpse.

Why did the murderer put so much effort into putting the corpse into a kneeling posture?

briar... cross... kneeling...

Weird medicinal smell.

Now, the big clue is succinylcholine.

The use of this drug, if it is through regular channels, is recorded for every milligram.

Unless the other party is a chemist who can extract this alkali.

Three hours later.

Zhang Yunhu and others completed the preliminary site survey.

"Xiao Chen, Lao Liu called you here too?" Zhang Yunhu's voice was a little tired. After a whole morning of high-intensity work, everyone would be exhausted.

"How is it? Did you find any clues?"

"Team Zhang, Master asked me to come and see." Then, he pointed in the direction of the corpse: "I didn't go to the corpse to observe closely, and I didn't find many clues."

Um?

Zhang Yunhu glanced at Chen Yan in surprise. Although he had been busy with work just now, he also noticed that Chen Yan was always on the periphery.

Originally, I just asked subconsciously, but I didn't expect that Chen Yan really had clues.

"What clue?" If it was someone else, Zhang Yunhu might not care, but the case of killing his wife the day before yesterday made Zhang Yunhu understand that Chen Yan is very good at finding details.

Since he said there are clues, then there may be some clues. UU reading www.uukanshu. com

"Team Zhang, I'm not sure yet..." Chen Yan frowned, "I need to confirm."

"Okay, anyway, the site survey is over, let's follow you."

Chen Yan didn't refute this time. The smell of succinylcholine was very weak, and his olfactory gene lock range was only 100 meters. He had to hurry up.

Following the smell of succinylcholine, Chen Yan left the classroom first.

Zhang Yunhu took the two vice captains and Liu Qingshan, followed behind Chen Yan, and did not disturb Chen Yan.

Outside the teaching building, the smell of succinylcholine suddenly decayed, and it was almost inaudible.

Fortunately, it wasn't long before Chen Yan was able to track it down.

Stop and go, I came to a garbage disposal station.

Two cleaners are taking out the garbage into the garbage truck.

"Stop!"

Across the distance, Chen Yan saw two cleaners about to dump a bucket of garbage, his expression changed greatly, and he hurried over.

The two cleaners wanted to continue dumping, but when they saw Chen Yan followed by a few policemen, they subconsciously put down the trash can in their hands.

Feeling the increasing smell of succinylcholine, Chen Yan knew that the source was in the trash can in front of him.

Fortunately, it was timely, otherwise it would have been dumped into the garbage truck, and it would have been difficult to find it after being compressed.

Looking around, Chen Yan picked up the garbage scissors next to the garbage truck: "Two brothers, please step back."

After speaking, he began to carefully pick up the trash.

"Xiao Chen, you..." Liu Qingshan stepped forward curiously, but was rotten by Zhang Yunhu.

"Don't worry, let's see what he's going to do."

Ten minutes later, Chen Yan picked up a pair of yellow objects and heaved a sigh of relief: "So I found you!"
