At noon, Ya Zi, Yin Ni, and Ye Dongfeng left the hospital and went to a restaurant for lunch. While eating, Ye Dongfeng was looking at the test results they had brought from the hospital.

Knowing that the monkey was a human in disguise, the group went to Zhu Botuan's school and collected DNA samples from people who had been in contact with Zhu Botuan for testing at the hospital.

It's just unexpected that after collecting so many, none of them could match the DNA of that single hair, which was only a few millimeters long.

"Ugh, why is it so hard to find this damn hair?"

While eating, Ye Dongfeng looked at the test results. He said, "We've collected data from quite a few people, including his parents, relatives, teachers, and classmates. But we still can't match them up. If it wasn't done by someone we know, then it's probably someone from outside. But how could a student like Zhu Botuan have contact with someone from outside?"

At first, everyone suspected that the murderer was someone they knew, because Zhu Botuan was a boarding student who rarely left the school. Even after school, he stayed at home and rarely went out, except to stay with relatives or go to internet cafes.

They had already asked many acquaintances to cooperate with the investigation, but still hadn't found anything unusual. Internet cafes were a bit more troublesome because the people there were a mixed bag, making it difficult to investigate. They also didn't know if Zhu Botuan had offended someone while using the internet at an internet cafe and was being retaliated against.

Yinni also looked at the test reports and said, "I also asked the school. They all said that Zhu Botuan seems to have no bad relationships with any classmates or teachers at school. He even has a good relationship with Huang Jian."

When Huang Jian was mentioned, Ya Zi wanted to sigh, because Huang Jian didn't remember anything at all and couldn't provide them with any useful clues.

Ya Zi said, "Sigh, this is really hard to investigate. How could such a normal person be killed by a fake monkey? What's going on here?"

Listening to Ya Zi's complaints, Yin Ni thought for a moment and said, "Alright, let's eat quickly. After we finish eating, we still need to go back to the school library and internet cafe to look for him. Take Zhu Botuan's photo with us and see if anyone recognizes him. If all else fails, we'll go in the direction of the Ouija board."

Huang Xiaojin's roommates had told her that they had heard about Ouija boards in the library, and that Zhu Botuan had played with them with Huang Jian. In the end, Zhu Botuan died and his soul disappeared, while Huang Xiaojin's roommates were haunted by a headless ghost.

Ye Dongfeng lowered his head and ate his rice, saying, "That's all I can do. Ugh, so frustrating~"

Ya Zi finished his meal in a few bites and said, "Then let's split up. I'm going to the internet cafe first. You guys can do whatever you want."

"good."

Ya Zi quickly went to the internet cafes that Zhu Botuan had visited before. Actually, the police helped him find them, so with the addresses, Ya Zi easily located those internet cafes.

When Ya Zi went to the first internet cafe, the owner mistakenly thought he was there to cause trouble because he didn't use the identity provided by the police. The owner even tried to kick him out, but when he saw Ya Zi pull out a police ID, the owner cooperated.

"Hey officer, you should have just said you were here on a case earlier, then we would have cooperated better. The way you're acting so aggressively and wanting to see our security footage makes everyone think you're here to cause trouble!"

An internet cafe owner said to Ya Zi with a helpless expression.

Perhaps because Ya Zi was having a bit of a headache investigating this case recently, his tone and attitude were a bit fierce when he questioned the internet cafe owner, which made the owner think that he was there to cause trouble. The owner even called out several internet cafe managers, and the scene looked like a fight was about to break out. Fortunately, the misunderstanding was eventually cleared up.

As Ya Zi watched those menacing-looking people approach him, he realized that he might have been misunderstood, so he took out his 'temporary' work ID.

"Police, please cooperate."

After the misunderstanding was cleared up, Ya Zi said a little embarrassedly, "Oh dear, I'm sorry, I just got my documents recently and forgot to show them to you."

In fact, Ya Zi wasn't wrong. They don't get this document often. The police won't just provide it to them unless it's absolutely necessary.

After seeing Ya Zi's identity, the internet cafe owner naturally cooperated with his investigation. However, he asked all the internet cafe managers and regular customers to look at Zhu Botuan's photo, but they found that no one could remember Zhu Botuan.

"Excuse me, we've never seen this person before. Could you please ask him what he did wrong?"

The internet cafe owner, being nosy, asked Ya Zi a question.

Ya Zi glanced at him, then put the photo away and said, "It's nothing. You'd better not ask questions you shouldn't ask."

"Um, okay, but this person seems quite young, is he a student?"

The owner walked over to the internet cafe's cashier and said, "Officer, don't worry, if we see this person, we will definitely call the police. Do you still want to see the surveillance footage?"

"No need, this is fine, thank you for your cooperation."

Ya Zi left the internet cafe without watching the security footage, because he felt that since no one in the internet cafe remembered Zhu Botuan, there was no need to watch the footage.
