Chapter 6 Section 6

After hastily glanced at the letter paper taken out of the envelope, Tang Chuan stuffed it back into the envelope again. Although he looked upright, he had no expression, and his eyes hidden behind the gold-rimmed glasses were extremely cold. He put the envelope on the desk, looked up at Kaoru and said, "Is Kusanagi okay?" "He's fine." "Yes, that's good." "Well, actually, I came to disturb you today..." Kaoru was about to explain why she came, but Yu Chuan interrupted her by raising his right hand: "That's what it says in the letter of introduction. It says maybe I won't be happy, but anyway, please ask me to give you some advice. He's got the right thing, and I really don't want to help."

Xun thought to himself, this man's words are really oblique.Are many so-called scholars like him? "But I heard that you used to assist the police in handling cases, didn't you?" "That was before, but it's different now." "why?" "Because of some personal reasons, it has nothing to do with you." "Would you please listen to me about the situation?" "It's not necessary. Because I don't intend to assist you at all. And this letter of introduction has already explained the general situation clearly. You want to know if you don't touch a finger of the other party at a certain distance. , the way to push people off a balcony, right?"

"It is estimated that it is not a living person, but a corpse." "It's all the same. All in all, I don't have time to think about this kind of problem for you. Sorry, please come back." Yu Chuan pushed the letter of introduction back to Kaoru. Kaoru didn't reach for the envelope, but stared behind the physicist's glasses. "You mean it's impossible?" "I don't know about this. I mean, this matter has nothing to do with me. I have decided not to intervene to assist the police in handling the case." Tang Chuan's tone sounded a little irritated.

"Please don't treat it as the police handling the case, but as simply asking you about physics, okay? Please think of it as a person who is not good at science and doesn't understand a problem, so he came to ask you for advice. " "Since this is the case, there are many people who can teach besides me, so you should find someone else." "The job of a teacher is to teach people. Is this how you treat the students who come to you for advice and shut them down?" "You are not my student. You have never attended my class, have you? You are just using the authority of the police to order others at will."

"That's not the case." "Please don't yell. Then let me ask you, how much scientific knowledge have you learned before? You said that science gave you a headache, so have you tried to overcome it? Didn't you give up completely early on? , turn your back on science and stop facing science? That’s fine, you’ll never deal with science again for the rest of your life. Please don’t get into trouble just waving a police handbook and running to order scientists to solve mysteries for you .” "I didn't order you..." "All in all, I'm going to live up to your expectations. I'm sorry, but those who teach also have the right to choose their subjects."

Kaoru lowered her head and bit her lips: "You say that because I am a woman?" "What did you say?" "You don't think I'm a woman, so you think you can't understand those science problems anyway?" Kaoru said, staring at the physicist. Tang Chuan couldn't help laughing: "If you say that, beware of female scientists all over the world throwing stones at you." "But……" "Also," Tang Chuan's eyes became sharper, pointing at Kaoru and said, "If you complain that you are a woman when your opponent's response is not satisfactory, I suggest you quit this job as soon as possible .”

Kaoru gritted her teeth tightly.Unfortunately, as this physicist said.At the beginning of choosing this job, she should have been mentally prepared to deal with all unfavorable conditions. It was not entirely nonsense that he had just said that he was abusing the authority of the police in an attempt to order scientists to solve the mystery for him.After she heard the rumors about Tang Chuanxue, she did take it for granted that he would not be indifferent when she came to discuss with him. "Sorry. We really need your assistance..." "It has nothing to do with whether you are a woman or not, but because I have made up my mind not to have anything to do with the police's search." Tang Chuan's tone returned to the calmness before.

"Understood. Sorry to interrupt you during your busy schedule." "Where. Sorry, I can't help you." Kaoru nodded and turned around.But before she walked to the door, she said: "I guess the murderer used candles." "Candle?" "First tie a rope to the corpse, hang it on the balcony, then fix the other end of the rope somewhere, and put a lighted candle next to it, and when the candle burns short, it will ignite the fire." Go to the rope and burn the rope—I don’t know if this method is feasible?" Didn't hear Yu Chuan answering, Kaoru turned around and saw that Yu Chuan was drinking the coffee in the mug while looking out the window.

"that……" "Then go ahead and try it out." He said, "Since you have an idea, go ahead and try it out. The results obtained through experiments are much more meaningful than listening to my suggestions." "Is this idea worth doing a hands-on experiment?" "There are no worthless experiments in this world." Tang Chuan responded on the spot. "Thank you, sorry for the inconvenience." Kaoru bowed his head to Yu Chuan's back and saluted. After leaving Teito University, Kaoru went to a convenience store.After buying all the candles, candle holders for candles, and a bundle of plastic ropes in the store, she went to Eshima Chinatsu's house.The port key was applied for when she left the police station, because she thought that if Tang Chuan was willing to come forward to assist in the search, it was necessary to ask him to take a look at the room.

As soon as he entered the room, Kaoru immediately started to prepare for the experiment.In fact, she originally planned to take something instead of hanging the corpse from the balcony, but in fact she couldn't really throw something down from the seventh floor.In desperation, she had to tie one end of the plastic rope to the railing of the balcony. The question now is where to tie the other end of the rope.The rope must be able to bear the weight of the corpse, so it is necessary to find a place that is strong enough.However, looking around the room, she couldn't find a suitable place.

In the end, she had to pull the rope to the kitchen, tied it to the faucet, and then put a candle next to it and lit it. The flame was about five centimeters above the tight rope. She looked at the clock and waited.The candle was slowly burning short. When the flame was about to join the rope, the rope creaked and burned.The rope connecting the balcony to the kitchen fell noiselessly to the floor. At this moment, there was the sound of someone clapping their hands.Kaoru was taken aback and walked out of the kitchen, only to see Yukawa in a black jacket standing at the door of the living room. "Wonderful! It seems that your experiment was successful." "Teacher... why are you here?" "Although I'm not interested in searching, I'm still interested in experiments. Besides, I also want to see with my own eyes how you, an amateur scholar, do things. Kusanagi told me about this place." "Are you here to mock me?" "If you don't think so, it doesn't matter." Kaoru walked back to the kitchen gasping, staring at the still burning candle. "What are you doing?" Tang Chuan asked behind her. "Looking at the candles." "What are you looking at it for?" "I wonder what it's going to look like when it's ordered." "It is true that there was no trace of a candle left at the scene, so it must be assumed that the candle had been lit at that time. But then again, why did you find such a long candle to do the experiment? It will probably take some time before it is lit. For a long time." Hearing what Yu Chuan said, Kaoru realized that it was true.Although a little annoyed, she blew out the candle without saying a word, folded it to a length of about one centimeter, and lit it again. "You don't have to stare like this all the time, do you? The candle will go out by itself." After finishing speaking, Tang Chuan turned and walked out of the kitchen, and sat down on the sofa. Kaoru took the scissors to the balcony, cut the rope tied to the railing, and returned to the house. "To be on the safe side, let me ask one more question, is it true that there was a plastic rope tied to the corpse at that time?" Tang Chuan asked. "No." "Then where did the rope go when it was burned by the candle?" "Well... it's still a problem. However, it cannot be ruled out that the rope was only wrapped around the corpse, and when the corpse fell, it was loosened and floated somewhere." "In other words, do you think the murderer did it with such a fluke mentality at the time, and in the end he really did what he wanted?" "That's why I said that there are still doubts about this point." Xun went into the kitchen to look at the candles. The candles had been extinguished, but there was obviously a pile of wax left behind.Although this result was within her expectations, she still couldn't help being a little disappointed. "Assuming that the candle will not leave any traces after burning, I don't think the murderer will use the candle." Tang Chuan said standing behind Kaoru. "why?" "Because the murderer could not have foreseen how soon after the murder others would burst into the room. If a man had come earlier than he expected, he would have found a candle burning." Kaoru pulled her bangs together, and scratched her hair with both hands. "Teacher, you are really an insidious person." "yes." "Since you know everything well, why didn't you tell me in advance, that this experiment was done in vain?" "You did it for nothing? I just pointed out the problem just now, and didn't say it was meaningless. Didn't I tell you that there are no worthless experiments in this world?" Tang Chuan sat back on the sofa again and raised his head Erlang legs, "Try it first - this attitude is the most critical. Among science students, there are also guys who only know that they are messing with theories in their heads without proving them into actual actions. This kind of students will not How many achievements. Even in the simple and clear situation, it needs to be verified. Only in the actual phenomenon can new discoveries be made. Although I asked Caosha to find out the address and came here, but if you didn’t come to do the experiment, I'm afraid I'll turn around and go back. Then I'm afraid I'll never be able to help." "Are you complimenting me?" "of course." "...Thank you." Kaoru whispered, sighing, even she herself felt impolite. "Judging from Kusanagi's letter of introduction, you are the only one who suspects a certain suspect, right? Could you please tell me the basis for your suspicion?" "There are several grounds." "Then please tell me all about it, as briefly as possible." "OK." Kaoru told Yukawa about the underwear box placed at the entrance, and that the password the victim planned to change coincided with Okazaki's birthday. Tang Chuan nodded, and adjusted his glasses with his fingertips: "I see. From what you said, this person is indeed a bit suspicious, but he has a perfect alibi in his hand, right? Since he saw it downstairs There is no way to investigate the scene of falling from the building." "But I always feel that the falling from the building itself is very strange." "how do I say this?" "The murderer had hit the victim on the head, but it is not clear whether the blow has killed the victim or only caused the victim to pass out. But in any case, I don't think the murderer pushed the person off the balcony. Necessary. If she is dead, you can leave her alone; There is also the possibility of being seen. No matter how you look at it, it is useless." "Could it be intentional to create the illusion of suicide?" "Both Kusanagi-senpai and the section chief think so, but since that's the case, the murder weapon should be disposed of. Kusanagi-senpai said that the murderer might have panicked at the time, but in fact the murderer was very calm and knew to kill the murder weapon." Remove fingerprints." "But it's true that the victim was pushed off the balcony, isn't it?" "That's right. So I think that the murderer pushed down the corpse not only to create the illusion of suicide, but also to have greater benefits." "You mean, it was for the purpose of making an alibi?" "Yes. Is it whimsical?" Yu Chuan stood up from the sofa without saying a word, and started pacing back and forth in the living room. "How to push the corpse off the balcony at a certain distance? This problem itself is not too difficult. The biggest problem lies in the problem of how to eliminate the traces mentioned many times just now. If something is used, it must be Leave traces." "But we found nothing." "That's just what it looks like. You didn't notice those traces, and you missed them. Now you must re-examine all the items in this room to find out the elements that can make the murder method established." "But how do I find this..." Kaoru looked around the room again, but she found neither a remote control machine nor a suspected timer. "Fundamentally speaking, your idea is not bad. You need ropes to hang corpses. As long as you find a rope that disappears after the corpse falls, the problem will be solved." "A rope that disappears?" "How can we cut that rope? And what should we use to leave no trace at the scene?" Tang Chuan stopped and put his hands on his hips. "Is the decoration in this room really the same as when the crime happened?" ?” "should be." Tang Chuan frowned and touched his chin: "Speaking of which, this room is really tidy. There is almost nothing left on the floor." "This also makes me very admired. At that time, the only thing that fell on the floor was the murder weapon." "The murder weapon?" Tang Chuan looked at his feet, "There is nothing there?" "Indeed not, because the forensics department has already taken it away." "Oh, what kind of murder weapon is it?" "It's a stainless steel pot." "pot?" "It's a saucepan. It's pretty heavy and strong, and if you hit it, you'll faint, if not die." "It's a pot. Where did it fall?" "I remember it's near here." Kaoru pointed to the side of the glass door, "and the pot lid is near here." She then pointed to the wall. "Huh?" Tang Chuan said, "Is there a pot lid?" "Have." "Is that so, the pot and the lid..." Yu Chuan turned to face the balcony and stood still.After standing still for a while, his eyes finally fell on the vacuum cleaner beside him. A smile suddenly appeared on his face.He smiled and kept nodding. "Teacher, I said..." "I have something to ask you." Tang Chuan said, "I want to trouble you to buy something." "What do you want me to buy?" "Do you still need me to say?" Tang Chuan smiled slightly, "Wok, you go and buy a pot like the one used by the murderer when he committed the crime."
