Yang Ye took two steps forward, put his arms around Gu Liang's shoulders, and led him towards the student dormitory building.
"Analyze one case at a time. Since we focused on the case of Li Yingwen and Meng Yuwen just now, let's go to their place first. Then your room."
Gu Liang glanced at him sideways, didn't say much, just followed him to the student dormitory.
The two did go to dormitory No. 103 first, where Li Yingwen and Meng Yuwen lived.
The situation in the two people's room at this moment has hardly changed from that of the first stage of investigation.
It took 10 minutes to search in detail, but Yang Ye and Gu Liang did not find anything of value in the end.
Walking out of room 103, on the way to 102 where Gu Liang lived, the two met Wu Shengsheng.
Wu Biology was carrying a garbage bag, and the smell of tangerines and oranges came out clearly through the plastic bag.
Yang Ye thought of something, and asked her: "Before you were looking for drugs, you said you couldn't find them, but you found a lot of orange peels?"
Wu Shengsheng nodded: "Not only, but also the pulp. I don't know who peeled a lot of oranges, but didn't eat the pulp. I think it's weird. But I asked many players along the way, and they all said they didn't do it by themselves. What about you? Have you ever done this?"
Yang Ye shook his head, then looked at Gu Liang beside him. "I don't. What about you?"
In fact, this is a very difficult question to answer.
Tangerine The orange is peeled, but the pulp is still there, indicating that the person is not actually eating the orange. His behavior of peeling and not eating the pulp is already a bit strange.
Wu Shengsheng has already said it and asked other people, but no one admits that he has done this.
So if Gu Liang doesn't admit it, it means that no player dares to admit it.
No one dares to admit it, it can only mean that there is indeed an article behind these orange peels and pulp. In this way, by following the clues, everyone may find the murderer's method.
But Gu Liang couldn't admit it directly.
Sooner or later everyone will think of the balloon explosion, and sooner or later they will see tools such as fishing lines on the roof.
If he admits it now, it means indirectly admitting that he is the murderer.
The lesser of two evils. Gu Liang had no choice but to deny it first.
As soon as Gu Liang denied it, Wu Shengsheng's eyes lit up. "No one admits it? So there is a problem! But, peeling the orange and not eating the pulp, what does it have to do with killing people?"
"I can't think of it for the time being. Show me." Yang Ye stretched out his hand, and Wu Shengsheng handed him the garbage bag.
Yang Ye took the garbage bag and asked Wu Shengsheng again: "Did you still not find the drug or something?"
Wu Biological shook his head. "So I can't figure out how the murderer killed people in our dormitory right under my nose. He couldn't have strangled Zhu physics to death. Zhu physics can call for help, at least he will struggle. If there is any commotion, I will can always be heard."
Yang Ye asked her: "When was the last time you saw Zhu Physics? Can you tell me about your timeline last night?"
Wu Shengsheng frowned, and Yang Ye said again: "I think that if you were the murderer, you wouldn't commit the crime in your dormitory. The suspicion of you killing her is relatively small. If you didn't do anything else, I think that last night You can briefly talk about the timeline after the dinner. Based on your timeline, maybe we can deduce something of great value. At least... we can initially confirm the range of the death time of Zhu Physic."
Wu Shengsheng thought about it for a while, but he also said: "Okay. I can say. The dinner party ended at 8:30. I ran for a while on the playground and returned to the dormitory at 9 o'clock. After taking a shower It was 9:30. During this period, I haven’t seen Zhu Physics. It’s just that when I was running, I vaguely saw her going in the direction of the classroom, maybe because she wanted to do a problem.”
"She came back at 11 o'clock in the evening. When I came back, I greeted her, but she didn't respond. I didn't bother to care about her, so I went to bed by myself."
"I fell asleep for a while, and was woken up by the small movements she made. I got up and saw her sitting at her desk with her head bowed. I didn't know whether she was reading or writing. I was very unhappy. She, tell her to turn off the light and go to sleep. She didn't answer either. "
"I was so annoyed that I found a towel to cover my eyes, and finally fell asleep slowly."
"From my timeline, the time of her death was broad, from 11pm to 6:30am."
Wu Shengsheng noticed that when she mentioned a certain place, Yang Ye and Gu Liang looked at each other, as if there was something tacit.
Wu Shengsheng hurriedly asked, "Did you think of anything?"
Yang Ye turned his eyes away from Gu Liang, and said to Wu Shengsheng: "I just had a brief discussion with Squad Leader Gu, and I think Zhu Physics may indeed have committed suicide. Because she's 'awakened'."
After briefly explaining the meaning of "awakening", Yang Ye said again: "It is written in her diary that she does not remember how she discovered the truth. It may be because her emotions were very broken at the time, and her mind was already confused. The human brain has a protection mechanism, if something is particularly stimulating to a person, he may have short-term memory loss and temporarily forget about it.”
"However, although Zhu Physics has forgotten about it, we can speculate on what happened to her."
"You said just now that she went to the teaching building after the dinner, as if she wanted to review the questions. I think this is the key point."
"Think about it, where is the entrance to the basement? Where did Manager Wang kill Qian Huahua?"
Wu Biology understood. "You mean... Director Wang killed Qian Chemical, and wanted to take him into the basement and put him in the destruction bin. During this process... Zhu Physics might have seen something by accident, and she might... maybe have entered that basement?"
Yang Ye nodded: "Yes. It is very likely that she entered the basement and knew her true identity. After returning to the dormitory, she wrote a diary in grief and indignation, and finally committed suicide. Before committing suicide, she also destroyed her own hands."
"She is good at playing the piano and has always been proud of her hands. But after knowing the truth, she found that she can play the piano and has beautiful fingers, just because she was designed to be that way."
"Scratching one's own hand, hanging oneself silently...all of this makes sense."
"I'll have to listen to other people's timelines later. If there are no accidents, I think it can be basically confirmed that she committed suicide."
After chatting with Wu Shengsheng for a few more words, Yang Ye and Gu Liang went to the 102 dormitory according to the previous plan.
It took about five minutes to thoroughly check the place where Gu Liang lived, and concluded that the situation in his dormitory was not much different from the first stage of the search in the script.
So five minutes later, Yang Ye sat on a chair, took the orange peels and orange peels out of the garbage bag, put them on the table, and began to study them carefully.
After a while, Yang Ye looked at Gu Liang: "I didn't think about it when I was chatting with Wu Shengsheng in the corridor. Now I think this problem is still up to you to solve. What's the use of orange peel?"
"The climate here is relatively hot and humid. Logically speaking, the orange peel will not completely dry out overnight. But I found that the orange peel has very little moisture, and the skin is very rotten, as if it has been deliberately squeezed. Why?"
Gu Liang sat upright on the chair, staring at Yang Ye, and heard him ask again: "Encyclopedia Gu Liangliang, although you studied liberal arts, but because of your love for science, you also read high school chemistry? I was I learned it by swallowing jujubes, but I can’t remember clearly now, there is a principle in chemistry, what is it called?”
"That's it. Water and oil are incompatible, but water and alcohol are compatible. What's the principle?"
Gu Liang stared at Yang Ye for a moment, and replied: "Speaking more deeply, I can't answer it. But for high school students, I can indeed answer it. In high school, this phenomenon can be called the 'principle of like dissolves like'. The more similar the material structure is, the more similar it is." , the easier it is to dissolve.”
"Water is a polar solvent. The kind of oil you mentioned, if it refers to the kind used for cooking, is non-polar. It has a different chemical structure from water, so it cannot be miscible with each other. But if it is glycerin, it is soluble in water."
Yang Ye nodded: "Understood. So... the oily structure inside the orange peel is organic matter, right?"
Gu Liang: "Yes."
Yang Ye: "What about rubber latex? Is it organic matter?"
Gu Liang: "Yes. Yes."
Yang Ye clapped his hands: "Then, can a balloon, or a banner, be used as a solute? And the liquid squeezed out of an orange peel can be used as a solvent? Based on the principle of like dissolves like, a drop of orange water hits a balloon, is it equivalent to... The effect of the balloon being pricked by a needle?"
Gu Liang showed surprise on his face. "Oh? You mean... the explosion of the inflatable banner was not an accident, but someone could detonate it? Why?"
Yang Ye put on a neat posture. "I don't know. For the time being, I can't imagine the reason why the murderer detonated the balloon. But you have always been good at restoring the incident. So I want to hear your imagination."
Gu Liang propped his elbows on the table, put his face on his palms, and indeed assumed a thinking posture.
He thought for a while, and confirmed with Yang Ye: "What time did the balloon explode?"
Yang Ye: "6:35. At that time, I was walking on the playground with the principal and director."
"6:35." Gu Liang tapped his face with his fingers in that posture, and then he straightened up and looked at Yang Ye, "We speculate that Li Yingwen and Meng Yuwen are from 6:15 to 6:00." Killed within 50 minutes. If the explosion of the balloon wasn't a coincidence, it was part of the scheme."
"So what's your idea?" Yang Ye asked.
In fact, Gu Liang's heartbeat was very fast during the whole process.
Gu Liang didn't really want to escape, but just wanted to delay the time when the truth was revealed until the moment when Yang Ye couldn't change the result.
So he really didn't take the evidence seriously.
He really didn't expect that Yang Ye would stare at him so early in his logic.
But Gu Liang was determined not to panic, so he said without changing his expression: "Talk about the first deceased this time—Zhao Xuexue who was crushed to death in the flower bed. If he was attracted by something at that time, someone knocked and approached It is possible to knock him unconscious with a brick. But there is no clue that something attracted his attention. We speculate that he should have just been waiting for someone at the flower bed."
"If he was waiting for someone, he would probably look around. In this case, it is unlikely that the real murderer would just throw a brick and knock him unconscious without attracting his attention or fighting him. Yes. Unless the person doing it is an athlete who is similar to a shot put and can hit it firmly and accurately."
"Now we know that there was a bug in Qian Huahua's body, and he suddenly had sports skills, so he was able to succeed."
"This principle also applies to Li Yingwen. She has an injury on the back of her head, and there is a thick dictionary next to it that can be used as a brick. She must have been smashed, and most of them were smashed first and then stabbed with a knife."
"Then how did she get hit? In fact, the truth is the same as Zhao Mathematics."
"Either, the murderer, like Qian Huahua, has a similar bug, and suddenly has this skill, and can throw the dictionary steadily and ruthlessly to knock Li Yingying unconscious; or... the murderer tried to attract Li Yingying's attention. , and then take the opportunity to commit crimes."
Gu Liang looked at Yang Ye: "The explosion of the banner would be a way to attract her attention. Attracted by the sound of the explosion, Li Yingwen went to look at the window. At this time, the murderer attacked her."
"If this is the case, you, the principal, and the director can rule it out. I sleep in the dormitory, and I rule myself out. It depends on who went to the cafeteria to help and who left halfway."
It is Gu Liang's strategy to try to lead the explosion of the banner to the murder method.
He couldn't let people think that the banner explosion was just used as an alibi for himself.
Compared with Gu Liang who was sitting very straight at the moment, Yang Ye was leaning on the back of the chair with his legs naturally separated, as relaxed as he could be. "When he heard the explosion, Li Yingwen would go to the window to watch, and the murderer took the opportunity to attack... Well, it is indeed a good idea. But there is a very critical problem."
Gu Liang: "What's the problem?"
Yang Ye: "If your imagination holds true, there are two possibilities."
"The first possibility is that there is an accomplice. In this case, the accomplice and the real murderer have made an appointment in advance. When the agreed time comes, the accomplice drips fruit juice on the balloon, and the real murderer takes the opportunity to commit the crime."
"The second possibility is that if there is no accomplice, the real culprit must have made a design similar to a delay device to make the banner explode at a certain time. Only in this way can he realize his plan, right?"
Gu Liang nodded.
Yang Ye said again: "No matter what the possibility is, whether it's making an agreement with the accomplice or making a delay device, the real murderer must have designed everything before going to the library."
"But there is a key premise in this matter. That is, only if Li English sat in the self-study area by the window, would it be possible for Li Yingwen to go to the window to check after the sound of the explosion came."
"Here comes the problem. The library is so big. Before the real murderer entered the library, how did he know... Li Yingwen was sitting by the window? If she was not sitting in the study area facing the playground, the murderer's The plan was a total failure."
"Of course, you can say, even if Li Yingying is sitting in another seat. The real murderer can talk to her first, say something about the window seat, and lead her to read there. But this is far-fetched."
"After all, it is a bit troublesome to design such a method of detonating the banner. It is not advisable to design such a plot just to attract Li Yingying's attention and make it easier for the real murderer to take the opportunity to kill people. There are so many books in the library, find a way Read a book with her, or ask her to help solve a difficult problem... There are 10,000 easier ways to attract her attention."
Gu Liang frowned, secretly a little annoyed.
After a while, Yang Ye stood up, walked in front of Gu Liang, bent down again, and pressed Gu Liang's wrist with both hands.
Continuing to lean over, Yang Ye's nose was pressed against Gu Liang's, and he could faintly see a few drops of sweat on the tip of Gu Liang's nose.
Yang Ye asked in a low voice, "The air conditioner is turned on in the dormitory, is it still hot?"
Gu Liang nodded: "After all, it's summer."
"Gu Liang, your brain is generally very reliable, and you wouldn't make such a low-level mistake. Isn't it..."
Yang Yeban tentatively asked, "Do you like me so much that you are a little panicked?"
After a while, Gu Liang smiled and said, "I'm not a murderer, why should I panic?"
Speaking of this, Gu Liang's voice became very gentle, "But you are right in the first half of the sentence. I like you very much."
At this moment, Gu Liang's eyebrows and eyes were gentle, and he was caught off guard by his confession.
Yang Ye's heart skipped a beat, and he immediately became a little confused.
Then he pursed his lips tightly and thought to himself - Gu Liangliang really went all out, didn't he? What is he playing now? Beauty trap
Gu Liang raised his hand and held Yang Ye's hand instead.
Leaving his seat and standing up, Gu Liang tried his best to look at Yang Ye at the same level. "You are right. There is a problem with my brain. Let's go to the rooftop to see if the delay device is really possible. Then we will push slowly, why did the murderer design this thing."
