Luo Han recounted what happened today:

"I felt that there was something in Mr. Xi's words, as if he knew something, and he didn't tell me. Of course, he thought I was just a student, and there was no need to tell me when he finally talked about returning to the light..."

"You mean he probably saw something, heard something, or smelled something in the '16 knife incident'"

"I'm more focused on the last one. He said someone was laughing in front of the corpse, which probably refers to the three boys. So he was in the crowd at the time? He felt something unusual. If he really smelled something, I can think of three people.

There are three possibilities: English Teacher Lin’s perfume smell, Senior Mathematics Teacher He’s cigarette smell, and Communication Studies Teacher Zheng’s medicinal smell. Which one is he going to talk about? Something is wrong..."

"You seem to be still stuck in the idea that the murderer is the person around you."

Luohan ignored it and continued talking to himself:

"What happened today...and Teacher Lu...I doubt..."

He looked directly into Shun's eyes and said in a very convincing tone:

"I highly doubt it"

"You mean...the murderer?"

"yes"

"When can we act?"

Luohan shook his head:

"No, it can't be moved. There is no evidence."

"Then there is always reason for your suspicion?"

"The current case has a very strange characteristic. In my opinion, only one person can meet this condition, but the basis of this theory remains at the hypothesis stage."

"That is to say, if the case is the same as your imagination, then that person is quite suspicious. You just had such an idea in a flash, and it is very likely that it is completely irrelevant. Even if you guess it right, there is no evidence."

"It is true that I have no clue about the cause and effect of the case. I have no idea what happened. This time things are completely different from before."

"I think it's very ordinary. You've dealt with things much more difficult than this before."

"It's not a matter of difficulty. It doesn't feel right. How can I say it's not a system? In the past cases, no matter how complicated they were, I could quickly and almost immediately see that something was abnormal, or something was too normal. Things are now too normal.

No, I don't see anything suspicious... They are all the most ordinary and daily activities, class, eating, self-study, sleeping. We lived like this today, and it will be the same tomorrow. The only thing wrong is that people died from five years ago to today.

, so many things have happened - by the way, I haven't had time to thank you for investigating these things - but... there are too many uncertain things. Which ones are murders? Which ones are just ordinary incidents? It is related to the things we are investigating.

Are all these things the same thing? Or are they several things? I won’t go into details. As for the ‘tragedy five years ago’ and the ‘16 stabbings’ incident that I am most exposed to now, I don’t know if they can be related. What else?

The feeling that keeps haunting me..."

"Still the same sentence: 'This is not a detective novel...'"

"Yeah, lingering"

"This case...let's put it this way...is really special. Is there really no way to find a breakthrough?"

"I have been trying, and it feels like I was a child. I was about 6 years old. One day I went to my uncle's house to play, and my cousin lost his temper because she liked a beautiful dress and his uncle wouldn't give it to her.

When I bought her, she was crying and fussing, jumping around, and refused to say anything. As a result, the necklace around her neck hung on the drawer handle... Don't show that expression, don't worry, nothing unfortunate happened, it was just that the necklace broke at that time.

She loves dressing up and often secretly puts on my aunt's lipstick. She usually wears more than three necklaces. Of course she was very sad because her favorite one was broken. She asked me to help her put it back on as it was. I collected the beads that fell all over the floor.

When I got up and took a look, I was dumbfounded. They were all imitation pearls, and they were all about the same size. Even though I was a god, I couldn't tell which one was from which."

"Then you just watch your sister rolling all over the floor?"

"Of course not. I just gritted my teeth and stamped my feet. Just put all the beads together. After I got through it, she finally broke down in tears and laughed. She will never wear it as a necklace again..."

“Still don’t like it”

"No, it's too long, so I have to put it on my shoulder."

"Oh, little girls are so easy to fool"

"The case is not that easy to deal with. I picked out a few from all the events and tried to connect them. If it didn't work, I changed to another few. This is a big project. Think about how many permutations and combinations there are? The existing things can't help me.

The biggest problem with whether to affirm or deny is that all the results are specious and unsatisfactory when you think about it. Just like the beads you finally selected and put them on, they look good when you put them there, but when you lift the two ends of the thread, they will crackle.

The earth scattered..."

Luo Han's eyes were very confused. Although he was usually like this, this time it seemed unusual.

"It's such a stupid method. It would be amazing if there could be a breakthrough like this. I think there is little hope of following the usual approach this time. This is the most fundamental...very basic...thinking problem."

"Then change your way of thinking"

Luohan showed a very soft smile:

"Easier said than done? You made the most difficult request."

Shun frowned and then shook his head:

"I have been observing for a long time, and I have to say that you are not in the right mood."

"You mean... anxious? Indeed, I am a little anxious. The motive is very important, and now there is absolutely... no, not even a guess. If we don't know the reason for the murder, we can't be sure whether people will continue to die. I just hope that the truth will not be revealed too much.

Later I realized that this would make my mind confused..."

"I'm not talking about this. You know you may be anxious, so you won't be anxious. I'm talking about another emotion, which is very negative. I also know that it is difficult to overcome. But the problem is that you seem to be willing to indulge in it and really want to control it.

?"

"I……"

"You are a sensible person!"

It was dark and heavy, and the air felt moist in the nose, making one's chest feel so tight that it was about to explode.

Zhang Ping came out of the school cafeteria and said to Luo Han next to him:

“Today is not bad, there are so few people eating”

"On Tuesday, all the colleges did not have classes in the afternoon. They all went home before it rained."

When they first go to college, most people are very homesick, because they can't get used to living in the dormitory, so they run home whenever they have free time.

"how about you?"

"There are no electives in the main course. Isn't it communication time in the afternoon? Besides, my parents moved out a few months ago. Now I'm the only one at home. It's not as lively as here."

"I gave up on this and made the dormitory my home." Zhang Ping looked at the sky, "By the way, have you ever seen a real crop field?"

"I used to see it from the car window during school outings"

"That doesn't count. In my hometown, there are acres of dazzling green. When the wind blows, it goes all the way down from here to there." Zhang Ping straightened his arms and waved them flat, simulating the scene. "Once, it was the same weather.

, a group of swallows flew close to the seedlings, coming and going in an arc... I can't say it's beautiful, it's elegant and easy to do. It was then that I realized that the swallows were not all black, they seemed to have a dark blue color on their bodies.

, I still suspect that I was dazzled by the wonderful sight at that time!"

"Then let's go to the front of the green grass and have a look. Maybe it will work."

"I saw that it was summer at that time. People say that Beijing has four distinct seasons, but I didn't know what month it was, and the weather was like this."

"Thanks to environmental pollution, there are only winter and summer left now, and spring and autumn have been gone for a long time."

“I don’t know if climate change will have an impact on animals.”

"If it continues to get worse, I'm afraid the swallows will never come again, and that kind of beautiful scenery will no longer be available."

"It doesn't matter, as long as you can afford the train ticket, go to our house. Remember, the weather must be like this."

"I know, there will be a chance in the future."

The two of them walked to the door of the dormitory building

"I suddenly remembered something, you go up first"

Luohan looked up at the sky:

"Oh, hurry up then"

Luohan walked through the dark corridor and stood at the door of 326. If it were normal, he would have heard the noise in the dormitory next to him, and he could "borrow some light"... It seems that everyone has really gone home.

Luo Han's eyes were dazzled, and he struggled to find the key in the keyhole.

The first thing I did when I entered the door was to turn on the light. I couldn't believe it was broad daylight.

He sat on the edge of Zhang Ping's bed, staring at the sky outside the window in a daze, as if he didn't want to do anything and didn't know how long it had been. When the door rang, Luo Han looked over and Wen Yu looked at him with an expression almost excited:

"I saw the lights on in our dormitory from afar. Sure enough, you are there."

Before he finished speaking, the phone rang

"Hey, Ashue, it's me, I'm here, I just walked in."

"Beautiful Lin didn't go home either?"

Wen Yu covered the phone, stretched his neck and said:

"Her home is far away, so she's afraid of getting wet in the middle of the road..."

Then, as if being pulled back by an invisible force, he clung to the phone again, his expression turning into a respectful and pious one:

"I'm here, I'm listening"
