Chapter 31 Section 3

Kusanagi stood in front of the door, staring at the schedule posted on the door.He found that Tang Chuan was blank in the classroom, laboratory, going out, rest, and rest.There was a blue magnet falling down under the door, Kusanagi lifted it up and knocked on the door. The door was opened by a young man with dyed brown hair. The 34-year-old Kusanagi thinks that science students are also very fashionable these days. "Is Yu Chuan there?" he asked. The student looked surprised: "Huh?" "If he's busy right now, I'll come back another day." "No, it's not very busy." The brown-haired young man opened the door and led Kusanagi in.

As soon as Kusanagi entered, he heard Yukawa's nasal voice. "If the cylinder sinks, you have to think about why it broke, what's in it, if it's corrosion because of a broken part. Why isn't there a leak in the front? What's causing the gas to burn?" Yu Chuan was sitting on a chair, talking with three students.Kusanagi thought, if it's about a research topic, it's better not to bother.But Yu Chuan had already seen him. "Hey, the guest came just in time." "Is it bothering you?" "It's okay, the study is over, I'm chatting casually. I just want to hear your opinion."

"What's this? I'm a science idiot, don't make me look stupid." "I don't know if I can make a fool of myself. It's this matter—" Yu Chuan handed the newspaper on the desk to Kusanagi. It was a newspaper from a week ago, and the society page was folded upwards. "Is it the explosion on the coast of Shonan?" Kusanagi asked. "I want to unravel the mystery of this incident. Are you asking the students to challenge this intellectual game?" The four students, including the young man who opened the door for Kusanagi just now, followed Yukawa's instructions with some displeasure.

"Regarding this matter, the Police Department is also collecting intelligence. Maybe some terrorist organization is deliberately finding fault." "You said it might be a terrorist bomb?" "This possibility cannot be ruled out. As long as that kind of bomb is ready, everything will be ok." "How does the Kanagawa police view this matter?" "Hey, the police in Tokyo and Kanagawa are old enemies." Kusanagi said with a wry smile.Relationships between police colleagues are complicated. "As far as I know, there is no trace of the explosives at the scene."

"Will it be washed away by the sea?" a student asked. "It's possible." Kusanagi did not refute the young man's opinion, but thought in his heart that if there was some kind of bomb, the police in Kamijigawa could not have found traces. "Does the police think it's a crime?" Tang Chuan asked. "We only carried out the search on the suspicion of a crime. After all, this kind of thing can't happen for no reason." "Have you reached a conclusion yet?" At this time, the get out of class bell rang, and the students left, but Yu Chuan stayed behind.

"The get out of class bell saved them." Kusanagi picked a chair that a student had sat on and sat down. "It's not science to arrange the formulas to solve the problem. It's more like this time, it's more necessary to gather wisdom to solve the mystery." Tang Chuan stood up and rolled up the sleeves of his white coat, "By the way, let's do something How about instant coffee?" "I'll let it go, there's a place I have to go to in a while." "Ah, so, is it near here?" "Near, just inside this building." "Oh?" Tang Chuan's eyes widened, "What's going on?"

"Didn't you read the news this morning? Why is it all old news from a week ago?" Kusanagi searched from the desktop. The materials and drawings were piled up in a mess, and there seemed to be no newspapers for today. "If there is something that can be used as a teaching material for me, just talk about it." "A dead body was found in an apartment near Mitaka," Kusanagi opened the notepad, "The male is 25 years old, his name is Fujikawa Yuichi, a former company employee. The person who found this body was the real estate owner of the apartment. Found Shi Fujikawa has been dead for three days."

"I saw that incident on the news yesterday. It is said that due to the heat, the body began to rot very early. The person who found the dead body was really unlucky." "The air conditioner at the death scene was always on. The prisoner wanted to reduce the leakage of the stench after corruption. But the recent 'Autumn Tiger' was so powerful that it exceeded the prisoner's imagination." "It's too hot." Tang Chuan said, "It's so hot that people's heads are dizzy, and they can't think of anything." Kusanagi thought, if you are afraid of the heat, just take off your white coat and you will be done.But he just thought so and didn't say anything.

"Does the name of the victim, Yuichi Fujikawa, sound familiar to you?" Kusanagi asked Yukawa. Tang Chuan looked bewildered. "Why does it sound familiar to me? Is he famous?" "No, not at all, but I think you might know him." "why?" "He graduated from the Department of Science and Engineering of Imperial University two years ago." "Oh, is it? The news isn't that detailed. What college is he in?" "Energy Academy..." Kusanagi replied, looking at the notepad. "He who studies energy, he may have taken my class. But I'm sorry, I don't have much impression. His grades in the exam are not outstanding."

"He's neither outstanding nor gregarious. That's the impression he's had on anyone who's seen him so far." "So that's the case. Then you came to the victim's alma mater on purpose, there should be your reason?" Tang Chuan said and adjusted his glasses.This is his habitual action when he shows concern about things. "It may not be a big reason." Kusanagi took out a photo from his coat pocket and showed it to Yukawa, "I found it in Fujikawa's house." "Hmm." Looking at the photo, Tang Chuan frowned, "Isn't this the parking lot next to our school building?"

"Since dealing with you, I have had more opportunities to come to your place, so when I saw this photo, I knew it was the parking lot here. Regarding this, the other investigators are very grateful to me, because they want to investigate what is photographed in the photo It’s not easy.” “Judging from the date of the photo, it should be August 30th, almost two weeks ago.” "I want to know what Fujikawa did at this university that day." "Could he have joined some group, came to the event as a special guest or something?" Kusanagi and Yukawa were members of the badminton team when they were students. "I contacted Fujikawa's classmate, but he didn't join any clubs." "If he didn't participate in club activities," Tang Chuan folded his arms, "could he be participating in the company's job fair or something?" "Absolutely not." Kusanagi asserted. "why?" "As I said just now, he used to be an employee of the company, but he resigned in July this year." "So he is unemployed now. Did he come here to find another job?" Tang Chuan thought for a while, and returned the photo to Kusanagi, "But, what is he doing taking pictures of the parking lot?" That's what I want to know." Kusanagi looked at the photo.In the outdoor parking lot that can park about 20 cars, there are a few cars parked, and there is nothing special in the photos. Kusanagi said that when Fujikawa was in school, he belonged to the fifth laboratory of the School of Energy Engineering.Tang Chuan said that if that was the case, an assistant named Matsuda should be very familiar with him. "Matsuda originally studied physics, and he was in the same class as me." Tang Chuan said as he walked in the corridor of the fifth research room. Kusanagi asked, "What are you studying here?" "The fifth research laboratory focuses on heat exchange systems. Matsuda's major is thermal science." "Thermal?" "Simply put, it is the study of heat and the thermal properties of objects. From the macroscopic perspective, it is thermodynamics, and from the microscopic perspective of atoms and molecules, it is statistics. Well, but there is no need to separate the two sides to consider." "Oh." Kusanagi thought to himself, it would be fine if I didn't ask. In front of the fifth research room. "You wait for me here for a while." Tang Chuan said, opened the door and went in without knocking. After about a minute, the door opened again.He showed his face and said, "It's settled, he can accept the interview." "Thank you so much." Kusanagi walked in. The room inside doubles as a laboratory, with measuring devices that Kusanagi doesn't understand at all. A thin man was standing at a desk by the window, wearing a half-sleeved T-shirt buttoned down to the chest.This house is very hot. Yu Chuan introduced the two of them.The thin man is called Matsuda Takehisa.Kusanagi and Yukawa sat on folding chairs in the room. "I didn't expect Yu Chuan to have a detective friend." Seeing Kusanagi's business card, Matsuguchi said.He said this without any contempt.Seeing Kusanagi take out a handkerchief to wipe his sweat, he smiled, "Excuse me, is it hot? I was doing an experiment just now." "Nothing, nothing..." Kusanagi originally wanted to ask what kind of experiment he was doing, but then he dismissed the idea—it’s better not to ask, anyway, he can’t understand it, so as not to regret it after asking. "I heard that you are here for Fujikawa-kun. Matsuguchi spoke first, as if he didn't want to waste time. "Does Mr. Matsuda know about this?" Facing Kusanagi's question, he nodded. "I didn't notice it when I was watching the news yesterday, but I remembered it when a graduate student called me this morning and told me about it." Matsuda turned to Yukawa's side, "Professor Yokomori also said just now brought up this matter." "Before he told me, I didn't know that the victim of this incident was a graduate of our school." Yukawa said to Matsuda, "Professor Yokomori must have been shocked too, right?" "Well, because it's not only the deceased's graduation research, but even the job hunting has something to do with him." "Excuse me," Kusanagi interrupted, "Who is Professor Yokomori?" "He's a professor at our school." Matsuda replied. He said that when Fujikawa Yuichi was in the fourth grade, Professor Yokomori served as a career guidance teacher. Kusanagi asked Matsuda, "Have you and Fujikawa met recently?" "He was here last month." If so, Kusanagi thought. "What time is it?" "It should be mid-term." "What is he here for?" "I don't think he has any special purpose, he just came here to play casually. There are a lot of students who come here after graduation, and I didn't pay special attention." "What did you all talk about?" "What are you talking about?" Matsuda thought for a moment, then raised his face again, "I think about it, it's about work, he said he resigned." "I know that. That company is called Nisina Engineering." "Hmm. Although it's small, I think it's a very good company." After speaking, Matsuda looked at Yuchuan, "Professor Yokomori is very concerned about this matter." "Original rice." Tang Chuan nodded. "whats the matter?" "Let me tell the rest." Tang Chuan closed one eye. Kusanagi sighed slightly, and turned his gaze back to Matsuda. "What did Mr. Fujikawa say about the resignation?" "He didn't say anything specific, and it's not easy for us to ask. He said he would look for a job again, and Professor Yokomori said something to make him feel at ease, and if there is anything embarrassing, he can come to him for discussion." Matsuda added that he didn't talk about the specific employment unit that day, and there was no news from Fujikawa after that. "So, since that day, Mr. Fujikawa has not been here again." "yes." "It's strange," Tang Chuan said, "he should have been here at the end of last month." "No, at least I haven't seen him." Matsuda said. Kusanagi took out the photo.Matsuda looked at the photo with a look of surprise. "This is the parking lot, what does this picture mean?" "It was found in Mr. Fujikawa's room, and the photo was taken on August 30." "That's true." Matsuda pondered, "Why did he take such a photo?" "In this Taixue, is it possible for Mr. Fujikawa to go somewhere else by the way?" "He has never joined a society, and I don't know whether he has acquaintances in the repetition group or graduate students. I don't know anything else." "That's right," Kusanagi put the photo away, "Is that Professor Yokomori here today?" "In the morning, I went out in the afternoon. I may not be back today." "Then I have to visit another day." Kusanagi winked at Yukawa, and Yukawa got up. "I'm sorry I didn't help you much." Matsuda said regretfully. "Is there anything else you can shed light on the matter? A very small one." Facing Kusanagi's question, Matsuda seemed to be thinking hard in his own way, but finally shook his head. "Fujikawa is a very honest and serious student. I don't think he should do things that are hated by others, and there should be no one who would benefit from killing him." Kusanagi nodded, saluted and stood up.That's when his eyes fell on a nearby dumpster.There were discarded newspapers and he picked them up. "Are you interested in this matter?" Kusanagi handed the news to Matsuda.Newspapers reported the explosion in the Shonan Sea. "This newspaper was brought by Professor Yokomori." Matsuda said, "But that incident is really incredible." "What do you think of that?" Tang Chuan asked. "Well, there's no clue. If it's explosives, that's the job of the chemists." "Nisina Engineering mainly accepts orders for piping equipment. Don't think of piping as ordinary water pipes, sewers, etc. They are in charge of heat exchange piping equipment for thermal power plants and nuclear power plants. Professor Yokomori is the company If there is a student who wants to join this company, please give him a call." Coming out of the fifth research room, Tang Chuan said. "So, Fujikawa joined that company because he was taken care of by the professor?" "Although too many people think this way, it is also possible to do the opposite." "how to say?" "Maybe the Nisina project will ask the professor to introduce excellent students to it. Even today when it is difficult to find a job, companies with low reputation still cannot recruit excellent students." "The professor recommends all good companies. However, the most important thing is my opinion, right?" 'This is where it gets more miserable.Although he is a fourth-year university student, he is still a child at heart. Few people really know what kind of company he should do and what kind of job he should do. So once he is recommended by the professor, there should be some people who join the company in a daze. .However, I don't know if Fujikawa is like this. " "The reason for resigning after just two years of work may also be here." Two people came out of the building and walked around the parking lot.The parking lot is basically square and surrounded by mesh, but access seems to be free.There are now 13 cars parked here. "Students are basically not allowed to park here. If they were allowed to park here, the place would have been fully occupied. The current students are really extravagant." Tang Chuan said. Kusanagi moved while holding the photo and comparing it with the real thing.The place where Fujikawa took pictures seems to be the building across the road. "Teacher, what are you doing?" A person approached Tang Chuan and asked.His long hair tied behind his head, "Are you up for some mischief in the car?" "I don't have a car, and now I want to buy one, so I looked at other people's cars in the parking lot and thought about which one to buy. Which one is better?" Tang Chuan asked, looking at the cars in the parking lot. The student glanced quickly and said, "Ms. Kijima's car is a BMW, and Mr. Yokomori's car is a Mercedes. It seems that none of them are in the parking lot now." Kusanagi looked at the photo, there were indeed BMWs and Mercedes-Benz among the parked cars. He showed the picture to the students. "Yes, these two are the teachers' new cars." The student said happily, then tilted his head and thought. "Is this photo taken at that time?" "Back then?" "When did it come? Well, a strange man took pictures of this area with a camera, ah, it seems to be the 30th of last month." Kusanagi and Yukawa looked at each other for a moment, and then immediately took out another photo, which was that of Yuichi Fujikawa. "Is it this person?" Kusanagi asked. The student looked at the photo and nodded slightly. "It feels similar, but I'm not sure." "What else does he do besides taking pictures?" "What happened? I didn't look at it, and I don't remember it, but he talked to me." "Oh? With you?" "Ah, he asked about the teacher's car." "The teacher's car?" "He asked me which was Professor Yokomori's car. I told him it was the green Mercedes." Kusanagi looked at Yukawa.While rubbing his chin, the young professor cast his eyes into the distance.
