"Huh?"

Liu Zifeng didn't start the car, but turned his head to look at Jiang Bai.

"Have you noticed that Cheng Xiaoman does have a look of wanting to say but not daring to say after hearing Wang Xinyu's relevant information."

Jiang Bai said, "But when you last mentioned the principal, she was terrified! ”

Following what he said, everyone recalled.

Cheng Xiaoman did have a moment of panic.

"You mean, the headmaster should have warned more?"

Liu Zifeng analyzed, "If Cheng Xiaoman knows the truth, then the principal should threaten her." ”

It's not like it's a general threat, just make sure you don't say it."

Yan Xiyue said intuitively, "Unless it's a long-term threat and you've had to cause harm, you don't have such a frightened expression. ”

are all exposed on the face, how much psychological damage is this?

"But they won't be home until Friday the day after tomorrow, and we'll have to wait for the opportunity tonight and tomorrow."

Liu Zifeng said, "By the way, what about Professor Che's side? How's his test? ”

Suddenly, he remembered that Che Hao was doing DNA comparison before.

Whether Wang Xinyu is really dead depends on DNA comparison!

"There's still more time, let's go for a while."

Jiang Bai said, "Just get up and see if Che Hao has any other clues here." ”

Saying that, Liu Zifeng started the car and went to the mountain behind the school.

In the principal's office, Gu Lai sat in a chair and breathed a sigh of relief.

After a long silence, he laughed again.

"Why do you think it's a master, that's it?"

Gu said, picked up the small black mobile phone and dialed, "Hey, cousin, I've got it here, they haven't found anything." ”

"Well, I see, then I'll take care of my cousin's affairs directly."

Gu Jixin said, "If you have anything you may need, say it in advance, and I will prepare it for you." Jiang Bai and Liu Zifeng are not such easy to deal with. ”

"No, you don't! They've been persuaded by me! ”

Gu said, his original smile suddenly became serious, "By the way, this Cheng Xiaoman has to deal with it." ”

"Friday the day after tomorrow, right? I'll arrange it. ”

Gu Jixin said and hung up the phone.

At the same time, Jiang Bai and the others had already come to the cave in the mountain behind the school.

To their surprise, all the researchers who had been doing research in the cave had disappeared, and a lot of equipment had been taken away, making the cave look empty.

Jiang Bai called to confirm before that Che Hao should still be there.

"Coming?"

Just when everyone was wondering, Che Hao, who heard the footsteps, walked out, "What's wrong?" Is there anything strange about it? ”

He looked at the expressions of the four with a puzzled expression.

"Professor Che, where's your researcher?"

Jiang Bai asked.

"My researchers are all back."

Cha Hao explained, "Originally, the investigation of rare materials was over, so I asked them to go back first. I'm interested in the case, and I'm going to investigate it together at your place of residence later. ”

"What about the comparison results?"

Liu Zifeng's expression was a little anxious.

"There is a lot of will for the preliminary comparison, I asked the researcher to take the corpse to the laboratory in your city for further comparison, probably Li is Wang Xinyu."

Cha Hao explained, "But it's not clear why he only has bones left. ”

"By the way, Professor Che, we photographed this set of knives in the school cafeteria before, can you see if this kind of knives can be used for deboning to achieve the same effect?"

Jiang Bai sent the photo on his phone to Che Hao.

"What kind of knife is this? I've never seen it before! ”

Che Hao looked a little puzzled when he saw it, with a recurved scimitar that was diagonally pointed at the small hook.

He looked at the shape of the knife and the details on it, and his brain built a model and began to simulate.

It does seem to fit the bone well and shave the flesh out.

"You mean, after Wang Xinyu was killed, he used this method?"

Che Hao didn't dare to say it, this is quite a terrifying and even cruel thing!

But even if he didn't say it, including Yan Xiyue, he understood it!

"Won't you...... It's cruel! ”

Yan Xiyue covered her mouth, and a trace of panic appeared in her eyes.

"Not sure."

Jiang Bai shook his head, "I'm just offering a possibility." ”

"It's a good idea."

Che Hao saw another knife, "The shape of this knife is very similar to that used by the corpse splitter!" ”

He is an expert in biological sciences and has a certain amount of research on the shape of wounds and some of the weapons that cause them.

"That means it's likely that he split the body?"

Liu Zifeng was a little excited, if the suspect could be caught first, it would be much easier to solve the case.

"It's hard to say, his craft was taught by Liu Zhen."

Jiang Bai said this, and everyone was shocked.

They all felt that Liu Zhen might just be the owner of a chain restaurant that relied on his connections. didn't know that Liu Zhen was still an excellent chef!

"Then Liu Zhen will also be included in the scope of the investigation."

Liu Zifeng nodded, his eyes were much more serious.

Things are a little more complicated.

The original intertwined facts of Jingchuan County appeared in front of their eyes little by little through this series of investigations.

"By the way, where you live, my researcher left this cave, and I will leave too."

Che Hao said, "Is there a place to store the corpse?" ”

"I'll arrange this."

Liu Zifeng said, "We are now staying in a hotel across the three streets from the school, I will find someone to deal with it, and we will go back together later." ”

Although Liu Zifeng's car is a four-seater, the back seat can seat three people.

In this way, they left the cave and went to the hotel.

Not long after they left, Luo Fei's criminal police team members who were secretly investigating entered the cave and temporarily received the body from the general headquarters.

On the way, Li Qiming kept typing drafts with a small notebook.

It didn't take long for me to arrive at the hotel.

Che Hao opened a room not far from Jiang Bai's suite at the front desk.

They walked upstairs and went to the suite to discuss the case and the direction of the investigation.

"I think it's still Friday, and I will go to Cheng Xiaoman's house after school to ask again."

Liu Zifeng said, "It has been confirmed that Wang Xinyu is dead, so you can use this to make Cheng Xiaoman tell the truth." ”

"I think it's reliable. Tomorrow if you pretend not to go out to investigate, you can also see the status of the principal. ”

Du Yiheng said, "Just now I successfully hacked into the principal's computer, and the contents ...... Uh, not very exposed. ”

His tone became a little awkward, "I don't understand how a headmaster can like these things. Team Liu, I'll send you a little. ”

"Hmm."

Liu Zifeng said that some computer screen pictures appeared on his mobile phone, all of which were some overseas websites, and there were also many fragrant pictures.

"This headmaster's flowers?"

He Dazhuang leaned over and took a look.

"Don't look at it, these have nothing to do with the case, at most it proves that there is something wrong with the principal's life style."

Liu Zifeng immediately closed the picture, "Du Yiheng, is there anything else?" ”
