Chapter 20 Section 12

Yu Chuan sat in the passenger seat without saying a word, staring straight ahead, but Kaoru could tell that he was not admiring the scenery ahead. "Shall I play some music?" Seeing no answer from Yu Chuan, Kaoru had to give up and continue to concentrate on driving. "Teacher You Yong," Yu Chuan finally said, "he is not a scholar known for relying on original inspiration. He is the kind of scholar who expands and applies the research results that others have confirmed in his own unique way. He is constantly The type that repeatedly repeats a large number of experiments and accumulates data. Compared with the theoretical school, he belongs to the practical school. Although I personally think that his research is extremely important, and the data is also very valuable, but the professors are very concerned about his He didn't think highly of it. They kept saying he didn't have anything new and he was doing the same thing as the guys in engineering. That's why he was an assistant professor until he retired."

"yes?" This was the first time Kaoru had heard of this.Regarding Tomonaga Xingzheng's experience, although she had also heard the investigation results reports of other investigators, she didn't know what kind of researcher he was before. "I really like this teacher's approach. Theory is important, but time is also necessary. Sometimes new ideas and discoveries come from constant practice and failure. It is the teacher who made me understand this, so he is my precious benefactor." "Then what are you going to do with this teacher now?" Tang Chuan didn't answer her question, and Kaoru didn't ask any more, because she gradually understood the purpose of his trip in her heart.

She thought to herself that she should entrust him with carte blanche. The two came to Youyong Mansion, Namie asked them to enter the house with a look of doubt.It's okay for Tang Chuan to be alone, but Ke Xun also came together, which will naturally make her freshman wary. Youyong was reading a book in the living room, but saw him looking up at the two of them with a smile on his lips and a peaceful and serene expression. "Are you here with Miss Detective? So, you didn't just come to visit me today?" "Unfortunately, you are right. I have come today to talk to you about something important."

"It seems to be so. Well, you sit down first." Yu Chuan answered "Yes", but did not sit down, but turned to look at Namie.She seemed to have noticed something, blinked her eyes, looked at the clock on the wall again, and said, "Dad, I'm going out to do some shopping, and I'll be back in about thirty minutes." "Well, I see." It wasn't until he heard the sound of Namie walking out of the entrance that Yukawa sat down opposite Tomonaga.Kaoru was sitting at a table a little far away from them, and Yukawa's expression could not be seen from her position.

"You don't seem to want Namie to hear our conversation?" Tomonaga said. "Although this will have to be told to her sooner or later, but today I just want to talk to you alone, teacher." "Well, tell me, what's the matter?" Yukawa's back rose and fell slightly, and Kaoru could see that he was taking a deep breath. "It is said that explosive explosives were found at the scene of the fire, which is cyclotrimethylenetrinitramine. Teacher, you have used that kind of thing in "Analysis of Fluid Properties of Metals in Explosive Forming."

Youyong narrowed his eyes: "It's rare that you still remember the title of that paper, it sounds really nostalgic." "Teacher," Tang Chuan said, "I think it's very clear what happened, and I also know that you have no choice but to do so. But even so, a crime is a crime. How about it, you just turn yourself in." Hearing those words, Kaoru's heart beat violently.Although the conversation was exactly what she had expected, she still felt a little overwhelmed hearing his words in reality. However, the key person, Youyong, did not show the slightest embarrassment. He just looked at the former disciple with peaceful eyes and said, "Is it saying that I killed Banghong? With my current body?"

"As for the method of killing, I already have a complete concept in my mind. Indeed, it is really impossible for an ordinary person to do it. But teacher, it is possible for you to do it, because you are a 'metal magician' after all." Youyong laughed: "I haven't heard anyone call this name for many years, it's really nostalgic." "I heard it seventeen years ago. I was told that year, when you included me in one of your experiments." "Really, it's been seventeen years." "Teacher, please turn yourself in." Tang Chuan said, "Although I don't know whether it is legally a surrender for you to confess your crime, teacher, the police have not yet had the slightest doubt about you. If you confess now If you go to tell the whole situation, you will definitely be given a lighter sentence during the trial. Please agree to my request!"

Hearing this, the smile on Youyong's face suddenly disappeared, as if it had turned into an expressionless Noh mask, and he stared at Tang Chuan with cold eyes and said, "Since I'm talking about this, I think there must be a basis for it." right?" "I've analyzed the shards of glass." "Glass...and then?" "I investigated the fracture surfaces of those fragments one by one, and analyzed them with a computer. The results told me that the force of the glass breaking was not from the outdoors, but from the indoors. Supplementary explanation, for reference only, I judge the glass The basis for which side is facing inward is to see which side has shredded tobacco mucus sticking to it."

"Then what? If the glass shattered due to force on the inside, does that mean I'm the murderer?" "The glass was not simply broken. First, something penetrated the glass at a very fast speed. Affected by it, cracks appeared on the whole glass, and the rest of the glass shattered and fell. Judging from the situation at that time, the penetrating glass It is the same object that penetrates Mr. Banghong. The police speculate that it is a Japanese sword, but it is actually a sharp weapon flying at super high speed. Only a 'metal magician' can do this." After hearing what Yu Chuan said, Kaoru was extremely shocked, and was so impulsive that she wanted to take out a pen to take notes.But in fact, before Tang Chuan came, she had already asked her not to record today's conversation.

"If you don't want to surrender, teacher, then I have to tell the truth to the police on your behalf. In this way, I have to do experiments to prove it. Teacher, please don't force me to do this." Although his His tone was flat as usual, but his voice was full of pleading. However, he shook his head slowly: "I can't do it. I didn't kill my son. The murderer was not me, but someone else, a man with a Japanese sword." "teacher……" "Sorry, you go back. I don't have time to listen to your nonsense." "Why? Teacher, aren't you ready to surrender yourself?"

"Nonsense, haven't you finished your Arabian Nights yet? Miss Interpol, what should I do if I have already told you to come back but the guest still refuses to leave? What crime should this kind of behavior be? ?” After hearing Tomoyong's question, Kaoru was at a loss and silently looked at Yukawa's back. "Aren't you willing to surrender anyway?" Tang Chuan asked again. "Do you really think I'm free enough to talk nonsense with you?" Youyong said in a low voice. Tang Chuan stood up: "Understood. Excuse me." He turned to face Kaoru and said, "Let's go back." "Just go back like this?" "No way. It seems that I misunderstood." "Go slowly. Don't send it off." Youyong said, "Just take the door of the entrance with you." Tang Chuan saluted and walked towards the entrance.
