Chapter 3 Section 3

That was a week ago. The Metropolitan Police Department was notified that a hit-and-run case occurred in Setagaya. However, after detailed investigation, the police concluded that it was not just a traffic accident. A family a few minutes walk away. The family name is Morisaki, and the head of the household is Toshio Morisaki, the president of the import and export trading company. His wife is Yumiko, and his only daughter, Remi, is attending a girls' high school. The family of three lives together.However, on the night when the incident happened, Toshio Morisaki was on a business trip to Singapore.

According to Yumiko’s testimony, she woke up when she heard some movement around two o’clock in the middle of the night. She listened carefully and found someone on the balcony, which was connected to the three rooms on the second floor, next to their couple’s bedroom. , is Remi's room. After she heard the sound of the glass window being opened, she immediately realized that someone was about to enter her daughter's room, so she stretched her hand under the bed without hesitation. There was a shotgun hidden under the bed. The gun belonged to Toshio Morisaki, who had been on the shooting team in college and still loved hunting after graduation.

Of course, the gun is not kept under the bed all the time, this is just Yumiko's habit when Toshika is on a long-term business trip.In order to be able to defend herself in a critical moment, her husband taught her the most basic operation methods. She walked into Limei's room with a gun in her hand, and saw a man standing by the bed, about to do something to Limei, she immediately called out, and the man ran away in a hurry when he heard the cry, she pulled the gun When the trigger was pulled, the man jumped off the balcony. The man had arrived in a pick-up truck, and as he was fleeing, he knocked down nearby residents.

The prisoner was quickly arrested. He was a 27-year-old man named Nobuhiko Sakamoto who lived in Koto Ward. His family owned an electrician shop.Light trucks are the business tools of the family. For more than two months, Sakamoto has been pestering Remi Morisaki, so when the police asked Remi if she had any clues, Remi immediately said his name.Sakamoto's address was also immediately found out. He had written many letters to Remi, and the address was clearly written on it.Almost all the letters were thrown away by Remi, but fortunately she still kept one, which helped the searchers a lot.

The investigators immediately set off towards Sakamoto's house.Sakamoto has been huddled at home, perhaps resigned to fate, when the investigators interrogated him, he readily confessed. A very simple case - everyone thought so at this time. After 30 minutes of separation from Makita, Kusanagi drove his own car through the gate of Teito University.He parked his car in the innermost parking lot and walked into the old school building.This is the school building of the Department of Physics of the Institute of Technology, and the 13th research room is on the 3rd floor. Going up the stairs and approaching the room, he heard the slogan sound like "one two, one two" in a tug-of-war, and it seemed to come from the 13th research room.

Kusanagi tilted his head and knocked on the door, but there was no response from inside.In other words, the knock on the door was drowned out by the voices inside. He pushed the door open, and the sight in front of him made him unbelievable.Tables and chairs were all piled up in the corner, and many students were tug-of-war in the middle, and there were more than 20 students on both sides. Yu Chuan was next to him, sitting on a chair in a white coat, watching the students. As Kusanagi watched, the team on the right won.It seemed that everyone was tired, and some people were bending over and panting heavily.

Kusanagi patted Yukawa on the shoulder.The young associate professor turned his head and showed his white teeth: "It's you." "What are you doing?" "Didn't you see it? Tug of war." "I know that. Why the tug-of-war?" "Do a simple physics experiment called Tug of War." "what?" "Okay," Tang Chuan clapped his hands and stood up, "A guest is coming, let's do it again, everyone hold the rope." ah?One more time—the students muttered and picked up the rope and took their positions. Tang Chuan looked at Kusanagi: "It's rare for you to come here once, so let's play a game and guess which side will win."

"Ah, it's hard to say." "Guess based on your intuition and experience." "Alright," Kusanagi compared the teams on both sides, their physiques looked similar.He recalled the result of the game just now, and pointed to the team on the right, "This is it." "OK, if this side wins, I'll invite everyone to drink juice, otherwise you invite the people on the other side to drink juice." "Ok." "Do you have any advice for them?" "suggestion?" "Yeah, like, spread your feet out, lean your body back, and so on."

"That's what you said." Kusanagi watched the students think about it, and he remembered what the instructor said when he participated in the tug-of-war competition in the sports meeting: "The first and most important thing is to lower your waist." "Oh. You still have to lower your waist." Tang Chuan crossed his arms and said in a tone of admiration. "Yes, sink your waist down, spread your legs, and stand firmly. This is very important. If you stand upright, you won't be able to exert strength." "I see. Can you demonstrate how much it is appropriate to bend down?"

"How much to bend down? Well, just bend as far as possible. Kusanagi made a tug-of-war posture, lowering his waist as far as possible, and his buttocks almost touched the ground. "Students, do you understand? You have to follow the movements he demonstrated just now, and you must not ignore his advice. Alright, sink your waist down and pick up the rope." After listening to Tang Chuan's instructions, the contestants on the right did as required with wry smiles, but they always looked dejected. "Any suggestions for the other side?" Yukawa asked. "No special suggestion, just come here anyway."

"Then I'll let them use the incorrect postures you just mentioned to pull it out." Yukawa asked the players on the left to raise their waists slightly.From Kusanagi's point of view, this posture was very unstable.He felt that the outcome was clear at a glance. "Okay, let's start the next game, both sides get ready... One, two, three, let's go!" Amidst Yukawa's cheering, the game started, and the teams on both sides were desperately pulling, but to Kusanagi's surprise, the team on the right began to be dragged forward. "Sink down, sink down!" Kusanagi commanded loudly. However, his solidarity did not help, and the team on the right still lost cleanly. Tang Chuan turned around and smiled: "Don't forget to invite everyone to drink juice." "This is because you instructed them to lose on purpose." "Do you think so?" "Is not it?" "Then I want to ask you a question, why is it better to sink your waist?" "Of course it's because it's more stable that way. If it's stable, it's easy for Ke to spread his legs and use his strength." But Yukawa shook his head. "Wrong! During the tug-of-war, raise your waist to make it easier to stand firmly." "No way?" "Think about it, when you pull something low, the force between your feet and the ground is greater than when you pull something high. In technical terms, the vertical resistance increases, and the maximum friction also increases. Strengthening, that is to say, the kicking force of the feet can play the greatest role. If the opponent does not change the height, just raise the center of gravity on your side." "Understood?" Tang Chuan asked again. Kusanagi savored his words over and over in his head, and as a result, he felt a slight headache.He shook his head: "Anyway, I don't have to participate in the sports meeting." Yu Chuan laughed silently. He patted Kusanagi on the shoulder and turned to the students: "Clean up the house, everyone, and I'll make up another physics class for him."
