The first person the teacher suspected was Chen Xiaoyu, but there was no evidence to prove that it was him. The teacher had to continue investigating Chen Xiaoyu. Chen Xiaoyu knew that he must be the teacher's first suspect, because Chen Xiaoyu knew that he was a fake Mushishi.

When Chen Xiaoyu was distressed about how to get rid of the teacher’s suspicion, Chen Xiaoyu realized that someone seemed to be helping him, and he also got rid of the suspicion. When Chen Xiaoyu was investigating secretly, he found that this person was the one who helped him before, Chen Xiaoyu thought. : I have to find time to contact him.

When Chen Xiaoyu cleared the suspicion, the teacher had to continue the investigation.

Who is it if it's not Chen Xiaoyu?

For a while, the teacher didn't have a clue. After Chen Xiaoyu got rid of the suspicion, in order not to let the teacher again suspect that he let him show off, Chen Xiaoyu was ready to gain the teacher's trust. Chen Xiaoyu got the decision and got up and went to the teacher.

"Teacher, let me help you investigate together"

Chen Xiaoyu offered to help the teacher investigate. After the teacher knew that Chen Xiaoyu had cleared his suspicion, he agreed.

"Also, you will be with me in the following investigation"

"Okay, thank you teacher, I will not let the teacher down"

"Ok"

After Chen Xiaoyu got the teacher’s consent, he turned around. Chen Xiaoyu, who was walking on the road, lowered his head and thought. Now he has the teacher’s approval. How to throw this pot out? When Chen Xiaoyu lowered his head and thought, he didn’t pay attention to the people coming. Hit

"Ouch!"

Chen Xiaoyu frowned and was about to apologize. He looked up and found that this person had been aiming at him Zhang Li, so he had no idea of ​​apologizing. He just glanced at Zhang Li and was about to turn around and left, but Zhang Li did not want him to go. , Then said:

"Chen Xiaoyu, you don't have long eyes when you walk, don't you apologize if you bump into someone? Is that how you treat your colleagues"

Chen Xiaoyu turned around and took a look at Zhang Li, not wanting to communicate with him too much, and then turned to leave. Zhang Li looked at Chen Xiaoyu preparing, so he reached out and grabbed Chen Xiaoyu, and opened his mouth and said that Chen Xiaoyu was not irresponsible.

"Chen Xiaoyu, are you really going to apologize, this is because you hit me, you are not allowed to leave unless you give me an explanation"

Chen Xiaoyu was dragged and motionless, turned around and looked at Zhang Li and did not speak, but kept staring at him. Zhang Li was a little numb and couldn’t help asking.

"Chen Xiaoyu, are you dumb? You can't speak anymore"

"Chen Xiaoyu, are you really dumb? I remember you can talk, why don't you speak now?"

"Chen Xiaoyu, I'm talking to you, did you hear?"

"Chen Xiaoyu!"

"Don't you think you are similar to the aunt in the vegetable market, so much nonsense"

"you"

Chen Xiaoyu really couldn't stand his nonsense, so he opened his mouth. Zhang Li was speechless by Chen Xiaoyu's words. In the end, Chen Xiaoyu didn't want to apologize. He turned around and left angrily. Chen Xiaoyu glanced at Li Zhang and left. He didn't think much about his direction, turned around and went back to where he lived.

Chen Xiaoyu, who entered the door, remembered to find someone to carry the scapegoat. After experiencing the incident of Zhang Li, Zhang Li has been targeting him everywhere since he came in. It is better to let him carry the scapegoat, but how can this make the teacher suspect Zhang Li? Chen Xiaoyu thought of a strategy that made the teacher doubt.

At night everyone else slept, Chen Xiaoyu walked to the place where Zhang Li slept, quietly placed a letter with the code in an inconspicuous corner, and then unknowingly returned to his yard, Zhang Li had no idea. I was stared at.

The next day, Chen Xiaoyu went to Zhang Li and said that he was here to apologize. As soon as he walked in, Zhang Li stood in front of Chen Xiaoyu. Chen Xiaoyu said to Zhang Li:

"I'm here to apologize to you. I apologize to you for accidentally bumping into you yesterday. It was my fault. I should apologize."

"Oh"

"Aren't you going to invite me in and sit down?"

"Why are you asking you to sit in?"

"I apologized to you and said that I made a mistake. You should respond to me, otherwise it will be hard to make trouble with the teacher.

"Oh, too, then you come in"

Chen Xiaoyu successfully entered the place where Zhang Li lived. Chen Xiaoyu looked around, looking for the envelope that was placed yesterday, and found that Zhang Li had found it on Zhang Li's desk,'This is easy to do', Chen Xiaoyu thought in his heart.

After a while, the teacher came over, Zhang Li went out to greet him, and Chen Xiaoyu stood up from his position.

"Hi teacher, why are you here, teacher"

"Oh, I'll come and have a look"

"Okay, take a seat, teacher"

"Ok"

The teacher glanced at Zhang Li, and then at Chen Xiaoyu who was standing on the side, then saw Chen Xiaoyu walk to the desk and pick up a letter-like thing, then turned to ask Zhang Li

"What is this"

Zhang Li was a little confused and answered truthfully.

"I saw it in the crevice of my desk this morning. I don't know what it is."

"You don't know, this was found in your room, would you not know?"

"I really don't know what this is"

"Since you don't know, let me tell you what this is"

"What is this"

"This is evidence that the teacher investigated the undercover among us"

"What, evidence, but I don't know, I don't know what it is, let alone the evidence that the teacher investigates the undercover agent."

"You don't know, but he is in your room. How do you explain this?"

Chen Xiaoyu looked at Zhang Li, Zhang Li turned to look at the teacher, and found that the teacher was also staring at him, panicked for a while, and quickly explained

"Teacher, I really don't know anything, I was wronged"

Zhang Li was panicked, afraid that the teacher thought he was an undercover agent. The teacher looked at Zhang Li with a suspicious expression. Zhang Li was more and more afraid of being topped. The teacher looked at Zhang Li in a panic. Ma, thinking,'I have to calm down, it wasn't me who did it, I didn't do it, I have to calm down, and I can't let the teacher doubt', Zhang Li calmly explained again:

"Teacher, it's him, Chen Xiaoyu, he framed me, it must be him"

The teacher still asked suspiciously

"This letter was found on your desk. You said he framed you. Why is he framed?"

"Teacher, maybe he put the forged letter on my desk. Besides, if I were an undercover agent, I would have hidden this letter. Huang Mingzheng would not put it on my desk like this. You are here to catch me"

"Makes sense"

After hearing this, the teacher felt a little reasonable, so he looked at Chen Xiaoyu and asked Chen Xiaoyu:

"Chen Xiaoyu, how do you explain it?"

Chen Xiaoyu answered calmly

"Teacher, Zhang Li, first I found this letter on your desk. You said why you put it on your desk openly, maybe because you wrote it last night, and then you put it in the gap of the desk. Place, and then you picked it up this morning and put it on the desk, and you are going to send it out today. You put it in the gap of the desk, even if someone sees it, you will say it was picked up in the gap, as long as you If you don’t admit it, you will think that the teacher will not doubt you. Secondly, if you say that I framed you, how could I get this kind of thing from the teacher? You said I put it in your room. How did I do? When you came in, and when did you come in, so you are quibbling, thinking that you don’t admit it, and if you pass the responsibility to me, the teacher won’t doubt you, but you have too many loopholes."

Chen Xiaoyu's analysis was justified and well-founded. The teacher who was originally half-believing completely believed in Chen Xiaoyu and believed that Zhang Li was an undercover agent.

But Zhang Li didn’t give up and wanted to quibble

"Then why did the teacher come today"

"That's the case. Didn't I come to apologize to you today? Before I came yesterday, I asked someone to find the teacher and asked the teacher to give me a testimony, but I didn't expect you to be the undercover teacher the teacher has been looking for."

Chen Xiaoyu explained that Zhang Li didn't give up and wanted to quibble.

"I"

Zhang Li was unable to argue, and started to panic again. This made the teacher believe that Zhang Li was an undercover agent, and then turned and left. The next day, the teacher told everyone that the undercover agent found it, it was Zhang Li, and then explained it. This made everyone convenient. Believe that Zhang Li is an undercover agent.
