Listen to the fire

Ji Cheng stood at the door of the house and hesitated for dozens of seconds before taking out the key and opening the door.

The room was pitch black, Ji Cheng stretched out his hand to turn on the light switch, but Ji Zhou was not at home.

"Huh..." Ji Cheng let out a long breath, he was relieved that Ji Zhou was not at home.

The affairs of this world have already bothered him enough, and it would be a real pain if he had to quarrel with someone who looked exactly like his father when he came back.

After closing the door, Ji Cheng returned to his room.

Ji Cheng sat down at his desk tiredly, and lit the lamp on the desk.

The moment the light came on, Ji Cheng saw the money under the lamp.

Ji Cheng reached out and took it out and counted it, it was 600 yuan in total.

Ji Zhou gave it?

Thinking of this, Ji Cheng quickly got up and went to the living room.

The living room was still in a mess of cigarette butts and wine bottles. Ji Cheng went to the balcony to get a broom and a dustpan, and cleaned the living room. When he was tidying up the clothes on the sofa, Ji Cheng found the quilt he had covered Ji Zhou in the morning. Fold it over and put it on the arm of the sofa.

Perhaps this home is not as bad as he imagined.

After tidying up, Ji Cheng went back to his room, sat down at the desk, and took out a notebook.

"Time-space replacement."

Ji Cheng took a black gel pen and wrote these four words in his notebook. This was the most critical clue on Li Zhengxin's phone, and it was also the reason why they wanted to kill Ji Cheng.

Space-time replacement.

Li Zhengxin also knows about parallel worlds?He is the same as himself, maybe not from this world?

However, what does time-space replacement mean, the exchange of two time-spaces?

No, no, how could the two space-times be exchanged?If you want to exchange, it can only be people in two time and space.

That's right, didn't I also come to this strange world now?

Ji Cheng suddenly remembered Liu Su's death case investigated by the Ninth Serious Crime Squad.

According to the biometric data report, the dead Liu Su was six years older than the original Liu Su's actual age, and the biological data of his parents did not match. Is it because of the replacement of time and space?

Perhaps Liu Su is not Liu Su at all, but a person from another time and space!

Thinking of this, Ji Cheng's hand holding the gel pen couldn't help trembling.

If this is the case, then Ji Cheng chased after the suspect that day, maybe the suspect deliberately wanted to escape to another time and space, but because of Ji Cheng's pursuit, Ji Cheng also followed?

With such a connection, the suspect Ji Cheng is chasing is very likely to have something to do with Li Zhengxin.

So, is the person who texted Li Zhengxin a suspect?

No, not right.

When the mysterious person sent the message to Li Zhengxin, Ji Cheng hadn't come to this world yet, and the person who most likely killed Liu Su should still be in Ji Cheng's world.

Therefore, it should be a group of people participating in the time-space replacement, and one of them should be the boss.

Moreover, this Boss can easily replace two people in time and space, so it means that this Boss should have a way to easily travel through time and space.

The one who can easily travel through time and space should be the person Ji Cheng drove after that day.

In this time and space, there are other people placed by the boss.

This case, if you think about it, is even more difficult.

Ji Cheng put down the gel pen in his hand, and looked at the relationship lines drawn by himself on the notebook.

At present, it is impossible to track down the boss who can travel through time and space freely. The only starting point is to find the person who contacted Li Zhengxin.

Ji Cheng took out the note in his pocket, on which was written "Xu Weichen, 158XXXXXXXX."

Team Xu's phone number.

To solve this difficult case, perhaps, he can help.

Anyway, now that I'm just a student, I can't be in a hurry to investigate this case, I can only take my time.

For now, just play the part of the student.

Ji Cheng turned off the lamp, took a shower in the bathroom, and then went to bed.

After Xu Weichen interrogated Li Zhengxin and investigated the monitoring of the Children's Palace, he should come to him again. Before that, he should play the role of Ji Cheng, a senior high school student.

Ji Cheng pulled the quilt and closed his eyes.

The next day, while Ji Cheng was still brushing his teeth, Wan Pengfei knocked on the door.

"Brother Deng, are you alright?"

As soon as the door was opened, Wan Pengfei reached out and grabbed Ji Cheng's hand excitedly.

"It's okay..." Ji Cheng replied vaguely, then turned around and walked to the sink to continue brushing his teeth.

Wan Pengfei followed behind Ji Cheng, and continued: "During the second class of self-study last night, Lao Xiang came to check, but you were not there, and you didn't answer when I called you, so I had to call Yi Su After sending the message, Lao Xiangzheng went into a rage, answered a call from the police station and left, did something happen?"

"Well, yes, someone is going to kill me." After Ji Cheng brushed his teeth, he put the toothbrush on the table in front of him.

"Someone wants to kill you?" Wan Pengfei's eyes widened, and his mouth also opened wide.

"Wait for me to wash my face, we'll talk as we walk."

Ji Cheng quickly washed his face, and went out with Wan Pengfei.

The two bought two pancakes from the stall at the gate of the community and ate them while walking. Ji Cheng probably told Wan Pengfei what happened in the past few days.

"So, brother Deng, you can't remember what secret you broke Li Zhengxin and the others?" Wan Pengfei asked after taking a bite of the pancake fruit.

Ji Cheng pointed at the back of his head: "Here, it was hit like this."

"It seems that the next day after your brain injury, you couldn't even find the school," Wan Pengfei nodded, and cursed unwillingly, "Damn Li Zhengxin!"

"Okay, don't talk about it, anyway, Li Zhengxin has already been arrested." Ji Cheng was talking, when he suddenly saw Yi Suone getting out of a taxi at the school gate.

Wan Pengfei also saw it, and said, "Hey, what kind of family is this little elk? Take a taxi to school every day?"

"Anyway, it's not our family." Ji Cheng looked at Yi Su's back, with a smile on his brows and eyes, and then started to chase after Yi Su: "Little elk!"

When Yi Suone heard Ji Cheng's voice, he stopped and turned to look over.

"Good morning." Yi Suone smiled at Ji Cheng who had rushed to his side very quickly. When he smiled, the curve of the corner of his mouth was delicate and perfect, which seemed to be inherently delicate.

"Morning...good morning." Ji Cheng smiled at Yi Su, and Wan Pengfei also panted and followed Ji Cheng: "Oh, my god, I'm exhausted, brother Deng, you are like a little elk Jackal, you know?"

Jackal?elk?

How does this sound like the feeling that I am going to eat Yisone?

Ji Cheng raised his eyes and saw that Yi Suone's eyes were still so clear, he cleared his throat, and then said: "Where is the jackal of shit, have you ever seen such a cute jackal like me? I am at most a Shiba Inu .”

"Why not Husky?" Wan Pengfei asked.

"Husky is too dick, brother Deng and I are so dick?" Ji Cheng stretched out his hand and punched Wan Pengfei.

The Wan Pengfei in this world was quite similar to the Wan Pengfei in the world he was in. When Ji Cheng was with him, he really felt that this Wan Pengfei was also his best friend before he knew it.

"Puhaha, Shiba Inu, it's pretty similar." Yi Song laughed at this moment, revealing a row of neat and white teeth that looked like shells, and his deep black eyes were curved like two crescents.

Ji Cheng looked at Yi Suone's smiling face, and for a moment, an inexplicable emotion surged in his heart. Ji Cheng quickly averted his eyes, and looked at the gate of Yuanshi Middle School in front of him: "Go!" Alright, class is on!"

After the three of them entered the classroom, the students in the class looked at Ji Cheng and Yi Suone, and started discussing with one another.

After all, Ji Cheng skipped class last night, and Xiang Yang was called away by the police. The students in the class were all wondering what happened.

Ji Cheng didn't want to worry about the students in the class, so after returning to his seat, he took out his textbook and read it.

During the exam yesterday, Ji Cheng realized that he still lost a lot of points. Since he wants to play the role of a good student now, he should put his study first.

"Brother Deng, the sun came out from the west today? Am I right? You're always doing physics problems?" Wan Pengfei rubbed his eyes. Ji Cheng's movement of calculating physics problems on the scratch paper made him suspicious for a while. I am dreaming.

"Wan Pengfei, how many exams did you take at the end of last semester?" Ji Cheng asked without looking up.

"Three hundred and five."

At this moment, Ji Cheng raised his head and stared at Wan Pengfei in front of him for several seconds.

If there is any difference between Wan Pengfei in this world and Wan Pengfei in Ji Cheng's world, it must be his academic performance.

The Wan Pengfei that Ji Cheng knew had the same grades as himself. He even won a prize in a physics competition in high school and was recommended as a recommended student.

"It's the third year of high school, study hard, and quickly make up for what you didn't understand before." Ji Cheng looked at him and said this with all his heart.

Wan Pengfei blinked: "No way, brother Deng, you took the [-] exam last semester, and you said I was [-]?"

Ji Cheng wanted to say something, but the class bell rang.

"Take a good class." After Ji Cheng said this, he lowered his head and continued to read.

Wan Pengfei: "..."

During the lunch break at noon, Ji Cheng was taken by Xiang Yang to the office to write a self-criticism, and those from Class [-] who fought with Ji Cheng were also sitting in the office.

What should come will come after all.

Director Liu went to investigate the fight, and although Jiang Gang and the others started it first, Ji Cheng still beat five of them, so there was still no way out of the investigation.

Sitting at Xiangyang's desk, Ji Cheng looked at the students from Class [-] who were sitting across from him, feeling a little complicated.

After all, Ji Cheng was a good student when he was studying. It was his first time writing a review, so he didn't know how to write.

Take out your phone and search for a copy.

"Teacher Xiang, all the math test papers have been corrected, come and get the math test papers of your class." A female teacher called Xiang Yang, and Xiang Yang responded and walked over.

Ji Cheng glanced at Xiangyang who was leaving, quickly took out his phone from his trouser pocket, searched for a review about fighting, and began to copy it.

When Xiang Yang took the paper back, Ji Cheng had already finished copying it.

"Teacher Xiang, my review." Ji Cheng handed the review to Xiang Yang, thinking that he should be able to leave after handing in the things.

"Don't hurry away, I'll take a look at your papers." Xiang Yang glanced at Ji Cheng, and began to rummage through the stack of math papers in his hand.

Ji Cheng had no choice but to stand beside Xiang Yang and wait.

When Xiang Yang turned to Ji Cheng's test paper, his hands were completely frozen: "130 five?"

Ji Cheng went over to take a look, feeling a little regretful: "Hey, the last big question and the third question are really wrong."
