Li Yifan, who was lying on the bed in the dormitory, repeatedly recalled what Jiang Dong said to him when he finally left.

"If it weren't for you, we wouldn't have suspected that Cui Liang's death would be a serial murder case, and it would have been impossible to find the scene so quickly." Jiang Dong said these words with his back to Li Yifan, and when the forensic and criminal police brigades and the people from the rat catching department came back and forth, Jiang Dong asked the people from the same team to drive their own cars to send Li Yifan back to school.

From finding the scene to the later investigation, Jiang Dong didn't let Li Yifan enter the room, he just looked at Jiang Dong in the room with a mobile phone flashlight with three other people, and the only thing he saw was the rats that ran out and the dead rats that had rotted by the wall. When he saw this, Li Yifan had already imagined the picture inside, after all, he was once in the body of the deceased, and he never wanted to experience those memories again, just looking at Jiang Dong in the room who slowly disappeared into the darkness, Li Yifan really sweated for him.

When he went to the scene, Li Yifan thought that Jiang Dong was still suspicious of him at first, but Jiang Dong's last sentence made Li Yifan's heart instantly feel that he was not such an ordinary college student, not the person who was disliked by his family, and it felt good to be needed. Li Yifan lay on the bed and slowly fell asleep.

In an isolation room next to the dissection room, Xia Zixuan and Jiang Dong were both wearing isolation gowns and armor, and Xia Zixuan and her assistant carefully cleaned up the maggots and mouse feces on the bloody corpses on the dissecting table.

"These large scratches and bites should be the main cause of heavy bleeding, and now the wound is seriously infected, and it cannot be ruled out whether there are other lesions such as plague." After the initial water was used to clean up the blood stains on the surface of the corpse and the feces on the body caused by the rupture of the large intestine, the whole corpse was no longer so horrible and rotten and unbearable to look at.

"Is it animal or man-made?" Jiang Dong looked at Xia Zixuan, who was seriously examining the corpse, and asked.

"I can't confirm yet, the wound was too badly damaged by the rats, only the scratch wound here on the arm is still intact, as I said earlier." Xia Zixuan glanced at the record written by the assistant next to her, and suddenly looked up at Jiang Dong at the door and asked, "Have you ever seen a fish hook?" ”

"Fishhooks?" Jiang Dong didn't understand why Xia Zixuan asked such a question inexplicably.

"Some animals, such as cats and wolves, have hooks on their paws, and this wound is, the flesh under the first layer of skin of this wound is too clean and neat, and this animal has to touch its claws to make such a wound!" Xia Zixuan signed the report.

"If it is, I mean, if it is man-made, then is this killing tool to be made by a special blacksmith?" Jiang Dong looked in Xia Zixuan's direction and said seriously.

"But this bite mark is caused by the bite of the teeth of a large sawtooth, how can this be artificial?" Xia Zixuan said as she looked at the photos on the wounds of the corpse taken in her assistant's camera.

"This? Let's investigate from many sources. Jiang Dong frowned, now this is the only clue that can be broken through now except for the video forum that Li Yifan said.

"Today, I can only get here first, I have to isolate first, and I have to come out with the inspection report before I can further dissect it." Bai Ran and two assistants put the body in a new isolation bag and zipped it up. asked Team Jiang to leave the isolation room together, and after coming out, he adjusted the temperature of the room, and went to the side to take off the isolation gown.

"Let's have something to eat together." As soon as he got out of the police station, Jiang Dong proposed to take Xia Zixuan and her assistant to eat together, although he couldn't smell anything in the isolation room just now, but that kind of scene did affect his appetite, but he had to express it so late.

"What time is it?" Xia Zixuan raised the watch on her wrist angrily.

"Okay, then I'll take you home." Jiang Dong said embarrassedly.

"No!" Xia Zixuan didn't turn around and left.

"Haha." Jiang Dong looked at Xia Zixuan's back embarrassedly and laughed awkwardly at the assistant next to him.

When Jiang Dong arrived home, it was already more than two o'clock in the morning, and after he washed himself again in the bathroom, he lay on the bed and recalled the two corpses he found today, thinking about the relationship between the two of them and Cui Liang, and why the murderer wanted to kill them. Jiang Dong suddenly thought of the video that Li Yifan said, the video was seen from the computer of their roommate Wu Shuai, could it be this Wu Shuai......

Jiang Dong deliberately didn't let Li Yifan enter the scene today, and deliberately sent him back to school before the on-site investigation, first, he didn't want Li Yifan to participate too much in their investigation, second, he was suspicious of his roommate Wu Shuai, and third, he didn't want Li Yifan to experience such a terrifying thing. Jiang Dong was wary of Li Yifan and felt that this young man was very worthy of sympathy, and this feeling of other people's death, pain and fear may only be felt by Li Yifan himself.

Regarding Wu Shuai's suspicion, Jiang Dong thought about it and felt that it was impossible, if it was revenge according to the owner of the abused animal, then there should be more of this person, these When the few of them arrived at the door, Li Yifan said something about Cui Liang, and these things were similar to the situation he asked Han Shuo to investigate before.

In Han Shuo's investigation report, it was mentioned that Xu Liang had received many complaints from the Animal Protection Association, but they were not dealt with due to insufficient evidence.

"The mobile phone found at the scene of the crime today, I will see all the contents tomorrow morning." Jiang Dong lay on the bed and sent a text message to Han Shuo to explain tomorrow's task, and now they found a computer and a mobile phone respectively in the two scenes, Jiang Dong always felt that these two things were like hints that the murderer deliberately left at the scene to give them. Jiang Dong fell asleep lying on the bed thinking about it, after all, he was too tired this day.

"The boss's mobile phone and computer have been restored, and I have sorted out the information here in the technical department, so I should be able to see it when I go to work." When he drove to the police station, Jiang Dong received a call from Han Shuo, and he pressed the phone on the steering wheel to hear Han Shuo's report.

"Okay, I'll be there in fifteen minutes." After Jiang Dong finished speaking, he hung up the phone and drove the car seriously.

Everyone was still resting on Sunday, but after receiving a phone call yesterday afternoon, they all came to their posts early this morning. Jiang Dong sat in his seat, poured a cup of strong tea, blew and took a sip, waiting for Han Shuo to bring back the information from the technical department.

"Boss, I've found an important piece of information."
