Chapter 8 Section 8

Pushing open the door, a figure in a white coat came into view.There is a transparent liquid in the test tube, and an alcohol lamp is heating it under it. A man in a white coat is filming this scene with a video camera. "It's very dangerous, don't get any closer." Tang Chuan said with his back to the visitor. "What are you doing?" Kusanagi asked. "A little explosive experiment." "explode?" Tang Chuan walked away from the test tube and pointed to the display next to him: "Isn't there a number displayed on it? This number indicates the temperature of the liquid in the test tube."

"It's 95 degrees now. Ah, it's 96." The numbers are still climbing.Just when the number exceeded one hundred and reached one hundred and five, the liquid in the test tube suddenly sprayed out, and the water droplets even splashed to Kusanagi and the others' feet. "One hundred and five degrees. It's roughly as I expected." Tang Chuan walked to the test tube, extinguished the alcohol lamp, and then turned to Kusanagi and asked, "Guess what's in the test tube? " "How could I possibly know?" "Just say what it looks like to you."

"What does it look like? I think it's just ordinary water." "That's right, it's ordinary water." Yu Chuan began to wipe the splashed tabletop with a rag, "It's just ultra-pure water made by ion exchange. Under normal circumstances, water will boil at 100 degrees. But instead of boiling suddenly, there are smaller bubbles first, followed by a phase of larger bubbles. However, if conditions permit, it can boil without going through these phases. In this case, the water does not boil in one It boils at the boiling point of Baidu, but suddenly explodes when it reaches a higher temperature. We call this phenomenon "bumping". He was scalded all over his body."

Kusanagi smiled wryly, and looked around the room: "It's been a long time since I heard your explanation. I feel like I miss this laboratory." "Have you done any research here?" "As for the experiment, I've seen it several times." As he spoke, Kusanagi took out a long and thin box from the paper bag in his hand, and put it on the table beside him. "what is this?" "Red wine. I don't know much about it either, it was recommended to me by the clerk." "You actually brought gifts? It's really rare." "It's a bit of a return, my back is causing you trouble."

"It's nothing, I just did a simple physics experiment." "Thanks to your help, the case was successfully solved, so I still have to thank you. However, I have some regrettable news to tell you." "Let me guess first." Tang Chuan took off his white coat and hung it on the back of the chair, "I solved the mystery, not the truth, right?" Kusanagi looked back at his old friend: "You already know?" "Well, I didn't think that was the case from the very beginning. I just tried to challenge to see if I could use the only things in that room to create a time-limited device that throws the corpse down. You I just said that your news is a bit regrettable, but to me, it doesn't matter; regret is not regrettable. I don't care, but I don't know what the female criminal policeman will think."

"That guy feels a little sorry." "Okay, what is the truth?" "It was suicide." "Sure enough. I guessed early on that it could only be suicide." Tang Chuan nodded. "How to say?" "Well, let's talk over instant coffee." What Yukawa took out were still two not-so-clean mugs, and Kusanagi took a sip of coffee with a wry smile: "It took us a lot of effort to find out that Okazaki belonged to Chika Eshima's boyfriend. Evidence. The key to these evidences is a card held by Enoshima Chinatsu. After investigation, we found out that it was a card from a love hotel in Chiba, with Okazaki's fingerprints on the card. According to Okazaki, he had already thrown the card into the trash can of the hotel before, but Ejima Chinatsu quietly picked it up again."

"Why did she do this?" Tang Chuan asked in surprise. "Does it need to be said? If you have this card, you can get a discount when you go to that hotel next time." "I see. Afterwards, Okazaki-kun completely gave up?" "No, although he admitted that he had been in contact with her, he denied any involvement in the case. He insisted that he witnessed the moment the victim fell from the building, so it was impossible for him to commit the murder himself." "So how did you do it?" "Although we knew it violated the regulations, we still let him watch the video, which is the video of your passionate experiment."

"Okazaki-kun must have been taken aback, right?" "The eyes are all round." Recalling Okazaki's expression at that time, Kusanagi still can't help laughing, "That guy was completely panicked, saying that he didn't know there was such a way at all, and he didn't do it. Then he told the whole thing, and admitted that he had beaten the dead man." "Is that the stainless steel pot?" Kusanagi nodded, and continued: "Okazaki has a wife and son, and he is just playing around with Ejima Chika, but Ejima takes it seriously. According to Okazaki, he has not promised anything. , but I don’t know when, Jiang Dao Qian Xia had the illusion that Okazaki would divorce his wife and marry himself. All in all, Okazaki went to talk about breaking up that night, but Jiang Dama Qian Xia was furious after hearing it , He said on the spot that he would call Okazaki's house."

"And then it's Okazaki's turn to get angry, right?" "According to what he said, he was angry and anxious at the time, and couldn't remember the specific details. When he woke up, he saw her lying on the ground. He thought she was dead, and he was so frightened that he only thought of running away." Then he left the apartment and encountered the incident of falling from the building. He said that he never dreamed that it was Ejima Chinatsu who fell. The next day, he learned from the news report that he finally understood the truth of the matter. After all, I found out that he didn't beat the woman to death at that time, he jumped off later."

"Then I remembered that there happened to be a pizza delivery passing by at that time, and I thought it was an excellent alibi, so I took the initiative to find the police station?" "Well, roughly so." "I see." Tang Chuan smiled and took a sip of coffee. "It is estimated that he will also be charged with intentional wounding. But he cannot be charged with murder, and we have no evidence in our hands to prove that he used that method." "What about that method?" Tang Chuan drank the coffee in his cup and shook the mug in his hand lightly. "Actually, it doesn't work. It can't be implemented at all."

Kusanagi was a little surprised, and looked back at his old friend: "Really? But isn't that video already..." "The experiment on that video was indeed successful, but do you know how much we went through to shoot that video? I remember that experiment failed at least ten times." Tang Chuan chuckled, "Sometimes The cord of the vacuum cleaner cannot be coiled back, and sometimes the lid of the pot comes loose all of a sudden, all in all, it is a series of failures. Utsumi-kun, right? It’s thanks to her patience that she stayed with me until the end.” "Why didn't that guy say a word?" "Of course, there's no need to mention it. You just need to publicize the successful cases. This is common sense in the world of scientists." "that guy......" "Isn't it good? Thanks to her whims, the case can be solved. She will make a good detective. I haven't encountered such an interesting thing for a long time." "Is it interesting? Then from now on..." Just when Kusanagi was halfway through his words, Yukawa, as if wanting to interrupt him, put his raised index finger on his lips, smiled slightly, and shook his finger left and right.
