Lin Yuechen looked at Liu Xi's angry little face and smiled a little proudly.

Even if your IQ is high, you are just a child now. Look, you can just cheat it out by just a random fraud.

"You are so despicable!" Liu Xi cursed in anger.

Lin Yuechen shook his head at him, "You are wrong. I'm not meant to be despicable. This is called "unnecessary deception". Little guy, learn it. Be careful not to be deceived easily in the future."

Lin Xi was so angry that she couldn't speak, and turned her head to ignore her with a cold face.

Lin Yuechen stopped when he saw it was ready and said nothing.

Seeing that the little guy ignored him, Lin Yuechen took out the information about the serial murder case from her bag. This was what she brought from Guan Miaoxin. She planned to take it home and analyze it carefully to see if she could find any useful clues from it.

Liu Xi didn't hear Lin Yuechen talking, and turned his head slightly curiously and saw Lin Yuechen looking there with a stack of suspected documents.

Liu Xi is not a person who cares about trouble, he just glanced at it and turned his head away.

Niu Xiaoli was moving very quickly, but in half an hour, she had prepared four dishes and one soup.

Lin Yuechen's refrigerator was stuffed with Niu Xiaoli, so she made a pot of pork buns, a spicy chicken diced rice, a cucumber, a 3-flavored rice, and a side dish soup with meat slices.

Although they are all home-cooked dishes, they are full of color, fragrance and taste at a glance.

Lin Yuechen put down the case information in his hand and went to the kitchen to help Niu Xiaoli serve food.

Liu Xi originally wanted to help, but when she saw the information Lin Yuechen placed on the table, she glanced at her curiosity.

When I glanced at it, I found that this was the information about the recent serial murder case.

Taking advantage of Lin Yuechen's helping to serve the dishes, Liu Xi and his group of Shi Min quickly finished reading all the information.

When he saw the last two words mentioned in the information, Liu Xi's pupils shrank.

After dinner, Niu Xiaoli drove Lin Yuechen and Liu Xi to the living room to view the electricity room, while she herself was washing pots and washing dishes in the kitchen.

"Are you investigating the serial murderer case?" Liu Xi looked at Lin Yuechen with a strange look.

"Yes." Lin Yuechen did not hide it. Anyway, Liu Xi is not an ordinary child, so she was not worried that Liu Xi would go out and say anything.

"Who are you? Why did you investigate this case? Are you from the police?" But didn't Grandma say that Lin Yuechen is a college student, and she is also a student of the No. 1 University of the Magic City, and this is not a police school.

Liu Xi thought that Lin Yuechen could find out the cases he had done at school, and she also felt that it was not surprising that Lin Yuechen was really a policeman.

But if she was really a policeman, how could she let him go? This made Liu Xi feel a little confused.

"That's right, although I'm not a policeman, I'm still a civil servant." Lin Yuechen didn't say anything more. She wouldn't tell ordinary people about the existence of Group Nine, so let this little guy guess it by himself.

Liu Xi was indeed as Lin Yuechen thought about it, and he had several guesses in his mind, but he didn't know which one was right.

Seeing that Lin Yuechen had no intention of explaining in detail, he didn't plan to ask.

"I saw that the word abyss mentioned in your information. Do you know what that means?" Liu Xi asked.

"Do you know?" Looking at Liu Xi's expression, Lin Yuechen knew that this young boy must have known something, otherwise he would not have asked her this.

Liu Xi nodded, "For the sake of grandma's face, I can tell you what I know."

"Do you really know? Why do you know? And what is the abyss?" Liu Xi would actually know something that so many people in their group nine could not find. No matter how he knew it, as long as someone knew it would be of great help to them solve the case.

"I can only tell you that the Abyss should be an app that provides revenge help."

"The app of revenge?" Lin Yuechen was puzzled.

"Actually, the night before I decided to attack those people, I installed an app called Deep Abyss on my phone. After I opened it, I found that the app was full of videos of me being Baling at school.

After the video was automatically played, a passage came out. I forgot what I said. Anyway, it was just one meaning. I asked me if I wanted to take revenge. If I wanted to take revenge, enter the name of the object of revenge. As long as I entered the name, I could get the power of revenge from the app called Abyss. I don’t know what the specific power it was."

"Let me borrow your phone to see." Lin Yuechen said to Liu Xi's cell phone.

"It's useless, I deleted it at that time. I, Liuxi, want to deal with a few clowns, and don't need to rely on anyone's power." That's right, he is so confident.

Lin Yuechen:...

"Thank you for the clues. This clue is very useful. After the case is solved, my sister will invite you to dinner." Lin Yuechen touched the young man's head and said.

Liu Xi slapped Lin Yuechen's hand away and expressed dissatisfaction with her behavior of touching herself without authorization.

Lin Yuechen didn't care, and his smile remained unabated.

"I would like to remind you that this app will specifically look for people who have been tombs in the school to provide them with revenge. If you want to find the murderer, you can find it from this."

Lin Yuechen nodded, and she also noticed this.

Since this app called Abyss is dedicated to helping people revenge, the victims must be people who have had an interaction with the murderer. As long as the victim's past is investigated, the murderer will soon surface.

After Lin Yuechen saw Liu Xi and Niu Xiaoli away, he immediately called Guan Miaoxin and told the other party the clue.

Guan Miaoxin didn't expect Lin Yuechen to find out what the abyss was so quickly. She immediately used the police's intelligence network to investigate the experiences of the deceased while studying.

Finally, it was found that the deceased had a good relationship in high school, either in the same class or friends who often stayed in class.

When they were in high school, they did have a boy named Feng Tao. Feng Tao's family was very poor, and even his schoolbag was sewn by his mother, and most of the clothes were given by others.

These people couldn't stand Feng Tao's poor appearance, so they joined hands with the people around them to dominate Feng Tao.

If you turn off the toilet and flush, throw someone's schoolbag to the trash can, deliberately knock over the lunch boxes that others brought to school, and push all the cleaning work to the other party. Of course, you can't clean it up after a meal every day.

Once, Feng Tao ran away under the siege of those people, and the group of people chased after Feng Tao.

Feng Tao was hit by a car while running away, resulting in his right leg being intercepted and he could only live in a wheelchair since then.

And those who harmed Feng Tao only lost some money to each family.
