“First, the bloodstains on the scene are not disorderly, but in the form of a wild rose,” Chen Yan shared his findings immediately.

“The scenes of the two murders are almost exactly the same. This is the murderer sending a message to the outside world. The cross symbolizes salvation, and kneeling symbolizes repentance. As for the wild rose, one of its flower languages means repentance! Therefore, the preliminary judgment is that this is a carefully planned revenge murder case!”

Shock!

Everyone looked at Chen Yan with eyes full of shock!

In such a strange murder case with no clue, Chen Yan actually managed to clear his head and tidy up the clues in such a short time, even preliminarily determining the murderer’s motive!

One must know that it was very important for the police to deduce the murderer’s motive from the clues. This was the key information to determine the murderer’s target group.

In a day, not only had Chen Yan found the gloves used by the killer, but he had also deduced the killer’s motive. This was simply unbelievable!

“Now, the most crucial clue is the relationship between the two victims. Since it’s a revenge murder case, the connection between the two must be very important… Team one, contact the technical department to get all the chat history of Lin Chao and Wang Xuefeng. Team two, focus on investigating the distribution and usage of Succinylcholine in Lian City… Particularly, focus on investigating whether the medical department of Lianhai University has the permission or conditions to use the drug. Team three, check if there are any recent criminal or civil cases involving the students or teachers of Lianhai University.”

…

Twenty minutes later, team one finished looking through the social media chat records of the two victims.

“Leader Chen, the two mainly used WeChat and QQ, but we didn’t find anything too unusual.”

Nothing too unusual?

Chen Yan frowned. “What do you mean by that?”

“It means that the two of them had added each other as friends once two years ago, but deleted each other after only a week.”

Chen Yan’s eyes lit up, “Quick, arrange for people to search Lin Chao and Wang Xuefeng’s computers immediately, especially Wang Xuefeng’s computers, including his personal computer and the computers he often used in school.”

Wang Xuefeng was a graduate student majoring in computer science. Since the current investigation was focused on computer research, it was a given he was the focus of Chen Yan’s attention.

The speed of the veterans on the search and arrest team was still very fast.

In just an hour, two team members ran in with sweat all over their heads.

“Leader! Leader! An important clue!”

“It turns out the two victims knew each other. Wang Xuefeng developed a simple chat software on the school’s server called Spirit Hostel. They are both members of the organization!”

“Leader, this is the list of members and the chat records.”

Chen Yan took the list and looked at it carefully.

“Leader, the results of the investigation involving Lianhai University have also come out. There have been a total of 12 cases involving Lianhai University this year.”

“Eight of them are teacher-family disputes, two have been of students suing the teachers for sexual assault, and two were students who had committed suicide.”

“Suicide?” Chen Yan raised his head, “What were the names of the deceased?”

“Yang Xiaoxiao and Xu Chang!”

As soon as the two names were mentioned, Chen Yan looked at the sky outside the window. It was already bright and the stars were sparse. He was immediately shocked.

“Captain, quick! Send someone to Lianhai University to find these two students — Li Hai from the Department of Architecture and Sun Feng from the Department of Mathematics!”

“The rest of you, arrest Yang Xiaoxiao and Xu Chang’s father immediately!”

…

Although Zhang Yunhu still didn’t quite understand what was going on, Chen Yan was now the leader of the task force, so carrying out his orders was the first rule.

After ending the video with the higher-ups, they immediately organized the police force to set off for Lianhai University.

However, Chen Yan and the others were still a step too late.

Li Hai and Sun Feng had disappeared.

At the same time, Yang Xiaoxiao and Xu Chang’s father weren’t at home either, so the arrest team had moved out in vain.

“Leader, what do we do now?” Liu Qingshan no longer called Chen Yan “Xiao Chen”.

In the police force, seniority was based on the premise that one was better than others. When one’s ability was not as good as others, they had to follow the rules.

For example, there were more than a dozen people in the search and arrest team, including Liu Qingshan, who had been in the police force longer than Zhang Yunhu had been, but the others had always been respectful and honest to the latter. Who dared to put on the airs of a senior?

This was the effect of ability and position.

And Chen Yan’s ability was outstanding right now!

Chen Yan’s face was ashen.

The murderers were more cunning than he had imagined… and more decisive.

Moreover, he now realized that the other party had no intentions of escaping justice.

He… No, everything they did was to stall for time.

Until all four of their targets were killed.

In fact, after reading the chat logs of the organization Spirit Hostel, Chen Yan even had the urge to help the two murderers, who were the fathers of the two suicide girls.

However, his duty as police prevented him from doing so.

Even if Lin Chao, Wang Xuefeng, Li Hai, and Sun Feng deserved to die, it should be the law that punishes them.

No one had the right to take another person’s life.

“Classroom 301 of the third teaching building and classroom 202 of the ninth teaching building, send someone immediately!”

Yang Xiaoxiao and Xu Chang were classmates. They were also Lin Chao’s classmates.

There were only four places where they went to class.

Other than classroom 204 and classroom 306 in teaching building twelve, where the two murders had occurred, there were only classroom 301 in the third teaching building and classroom 202 in the ninth teaching building left.

Yang Xiaoxiao and Xu Chang had a good relationship. They sat together in class every time.

One of the photos that team three had brought back was taken when Yang Xiaoxiao and Xu Chang were in class.

The two of them were in the direction where Lin Chao and Wang Xuefeng’s skin crosses and kneeling bodies were facing!

This time, the two teams arrived at the two classrooms in time.

“You guys came much earlier than I expected,” Yang Chenghan didn’t get hysterical, didn’t resist, nor did he take Li Hai hostage.

He simply turned around and disfigured Li Hai’s face with his knife.

…

In the interrogation room.

Chen Yan sat opposite Yang Chenghan.

The other party had insisted on seeing him.

“You are much younger than I expected,” Yang Chenghan, who was sitting on the interrogation chair, didn’t have the air of ruthlessness of a murderer.

On the contrary, he was an intellectual that seemed elegant and easy-going.

In fact, Yang Chenghan was indeed an intellectual.

He was the top professor in the Computer Science Department of Lianhai University, Yang Xiaoxiao’s father, and also Wang Xuefeng’s mentor.

Xu Chang’s father, Xu Bin, was Yang Chenghan’s colleague and the Vice Dean of the Medical Department of Lianhai University. He was the one who had extracted the Succinylcholine.

When the two of them killed, they injected Succinylcholine into the victim’s body, rendering the victim’s limbs useless so that they would be unable to resist or scream.

After that, they bled the victim, drew the wild rose, nailed the victim to the blackboard, and peeled his skin bit by bit.

After the victim fainted, they sprinkled strong alcohol on his wounds to make the victim wake up, then continued. In the end, the victim was still alive even when his skin had been completely peeled off.

This was why there was a smell of alcohol at the scene.

To have to watch his skin being peeled off, one could imagine how much fear the victims had suffered.

“How did you guys find out?” Chen Yan sighed.

Yang Chenghan knew that Chen Yan was asking how he and Xu Bin had found out the reason for their daughters’ suicide.

“Why didn’t you delete the chat room?” Chen Yan knew that as a professor in the Computer Science Department, he wouldn’t have found out if Wang Xuefeng had deleted the chat software in advance.

It would have also been impossible for him to solve the case so quickly.

“Something must be left behind. Death is too cheap for them.”

“Is it worth it?”

A professor and a vice dean…

Yang Chenghan adjusted his glasses and leaned forward slightly, “Officer Chen, if you had a daughter who suffered the same fate as my daughter, what would you do?”

Chen Yan was slightly stunned.

For some reason, the image of Shen Yunyi appeared in his mind.

Chen Yan did not reply to Yang Chenghan’s words.

Or rather, he… did not dare to.

Chen Yan would let the perpetrator know that death was actually the happiest thing in the world.

Moreover, he could swear that no one would be able to catch him.

The interrogation went exceptionally smoothly, and the two suspects admitted that they had worked together in causing the main wire of the surveillance system to be broken.

Yang Chenghan had brushed some honey on the wire, then let the laboratory rat that he got from Xu Bin gnaw at it, thus creating the illusion of an accident.

The purpose was to delay the speed of the police’s investigation.

In fact, the two of them had decided that if the police couldn’t solve the case, they would turn themselves in.

They did not expect the police to arrive so quickly!

Now, although their mission was not perfect since Li Hai and Sun Feng were not killed, both had been disfigured. Moreover, with such an experience, they believed that the two boys would never have a good sleep in their lives.

Revenge… complete.
