"One, two, throw the racket... One, two, throw the racket, stop."
Liu walked up to Kirihara, put his left hand on Kirihara's shoulder, and held Kirihara's racket with his right hand. With the back of his right hand, he then raised Kirihara's arm and threw it out seemingly lightly.
"Your arm was too stiff just now. Don't use your arm as an arm, and don't use the racket in your hand as a racket." After saying that, Liu led Kirihara to swing the racket again, "Feel this good. A soft, relaxed feeling. Your arm is now a lever. Use the force of your upper arm to throw your forearm out. The same is true for the racket. Think of the racket as a whip. Remember that your force should be very easy. , instead of being stiff."
"I'll try again." Kirihara broke away from Liu's control and used his shoulders to swing out with his upper arm and forearm. "It does seem to be easier."
"Yes, the movements are indeed much smoother."
Liu retreated to his position again and emphasized again, "What we are doing now There are no problems with his technique, explosiveness, or creativity, and his basic strength and physical strength are far superior to those of his peers. The only thing that can be improved is the method of power production, making the original heavy ball heavier and the fast ball faster. This is very important to us. It's simple, just stay relaxed, mobilize all the muscle strength of the whole body to focus on one point on the wrist, and swing the racket. Don't feel irritated and let your joints stagnate because you are tired or it has been a long time, and you don't need to hold the racket. It's very tight. The same principle applies to serving and returning the ball. "
Liu kept the rhythm of the team while chanting the slogan, and then started to swing the racket again.
According to the principle of leverage and the unstable equilibrium state of objects, as long as a suitable balance point is found for any object and a small disturbing force is applied to it at this point, it can lose its balance. Balance, so as to achieve the effect of leveraging force, allowing one's originally small strength to explode with great energy.
The same goes for serving. As long as you find a suitable point and angle of force, you can hit faster and heavier tennis in the easiest way. This method of generating force is not difficult to find. As we all know, the greater the kinetic energy, the heavier and faster the ball will be, and the kinetic energy of an object is equal to half the product of the square of the mass and the speed.
They cannot change the quality of the tennis ball, so the space available for operation is speed. In other words, the faster the speed, the stronger the spin, and the faster and heavier the tennis ball will be. What they have done is to replace the swing with a whip, which is to use more power from the body to add an acceleration to the racket. In this way, even the relatively thin Kirihara and Marui can hit the same shots as Sanada. Heavy ball.
As for why Niou, who is obviously thinner and thinner, is not used as an example, I'm sorry, he is not in the category of ordinary people.
At two o'clock in the afternoon, everyone in Lihai had lunch and started a short lunch break. They were discussing with their teammates who their first round opponent would be.Whose Nioh received a call from his sister Nioh Nahiro.
"Hello, sister?"
"Masaharu."
"What's wrong?" Nioh couldn't help but feel that his sister's voice was not as cheerful as usual. Frowning, "What happened?"
"It's nothing, I just beat up two scum. Do you have time to pick me up at the Tokyo Metropolitan Police Department now?"
" I'll be right away," Nioh stood up, "Wait for me."
"What happened?" Seeing Nioh in such a hurry, everyone else gathered around him after he hung up the phone.
"My sister had some disputes with someone. She is at the police station now. I will pick her up."
"Are you on your own? How about we go with you?" < /p>

"It's okay," Nioh waved his hand, "I can go by myself."
"No, no," Kirihara shook his head repeatedly and took Nioh's hand, "It's all going to the police station. Go, the other party must be a big, arrogant and unreasonable bad guy! What if you were bullied in the past!"
Hearing the word "being bullied" used to describe himself, Nioh couldn't help laughing, but facing Uigirihara's stubborn and serious eyes, Nioh had no idea of refuting. After all, it is a good thing for juniors to worry about their seniors, and they deserve recognition~
"In that case, everyone Just come with me, I want to see who dares to bully my sister."
At this time, Nioh seemed to be distracted by Kirihara's words and forgot about Nioh. Naixun's original words were "I just beat up two scumbags", so when everyone rushed to the police station, what they saw were two "big, arrogant and unreasonable villains" as Joo Chihara said, hiding with bruises and swollen faces. Picture in the corner.
As for Nioh Nahiro, except for some scratches on her arms, she was obviously fine. In addition, sitting next to her was a white-haired boy who also had no injuries and looked fierce. , that boy may not be known to others, but Nioh knows it - Yamabuki's future ace player, Aku Tsujin.
"Why are they a group of children?"
At this time, the two adults standing next to the two boys who were beaten into pig heads came over. One of them was obviously The more vicious person continued: "I don't care who you are. These two brats beat my child like this. Let's talk about compensation."
"Bah!" Niou Naixun He stood up, put his hands on his hips, and faced the man, "These two bastards went to bully a helpless old lady. I beat them like this. It's already a light thing. You still want to compensate? First, ask for your face." Let's go!"
"Don't be impulsive," the police officer watching from the side presided over the order, "This is the Metropolitan Police Department, I'm asking you to mediate, not to quarrel."
"What's going on?" King Ni asked.

"It's like this. After I practiced karate, I went to a ramen restaurant for lunch. Halfway through the meal, I saw these two bastards looking for trouble. They said they had eaten bugs from the noodles and wanted the owner to compensate. , I saw that they put it in themselves! They were deliberately trying to blackmail the shop owner. When I made it clear, the two guys started to fight. One wanted to beat me and the other wanted to beat the shop owner. So I Legal counterattack."
"Understood."
Nioh had no reason to doubt his sister's explanation, so he directly crossed his arms and glanced at the two bodies. A boy wearing a certain school uniform faced two tall adults.
"Your two children are also high school students. High school is a very critical stage. It is true that our country protects students in all aspects. Even if such a fight occurs, it will not Children will be punished other than education. However, there are state laws and school rules. If a student makes frequent mistakes or even violates the school's express regulations, the school can expel the student. You must know that in our country's education. This is a top priority. Think about it, if your child is expelled from school, what will happen to him in the future?"
Nioh pretended to think and continued: "Don't think that we don't have evidence. Or you can continue to transfer schools or something after being persuaded to drop out. You are all adults, don't be naive. There are so many surveillances outside. I just need to follow the trajectory of your children from home to school and then to the places they often go to. I need evidence. As much as you want."
"You——"
"Don't rush to refute, think about it, even if you have the ability to transfer them from one school to another. , what good does this do to them? The frequent changes in their lives will only make their already poor academic career worse day by day. Even if they reluctantly go to college in the future, their past will be revealed and made public. . You who have been beaten down by society for so many years should know better than middle school students like me. So, do you still want to continue to make trouble? ”
