The King of Net’s Strongest Strategist

A pair of pupils shrank slightly, Kirihara's eyes couldn't help but look at the tennis ball. The original trajectory of the tennis ball was constantly deviating and flying towards the outside of the court.

"Kirihara, haven't you studied fluid mechanics? In a normal return stroke, the tennis ball moves in a straight line at a certain speed. At this time, the airflow will only produce resistance to the tennis ball.

After a pause, Renji looked to the opposite side,"But the tennis ball is rotated through friction." When a tennis ball spins while flying in the air, it also causes the surrounding airflow to rotate.

On one side of the tennis ball, the airflow generated by rotation is in the same direction as the relative airflow during flight, so the airflow speed increases; on the other side, the airflow generated by rotation is in the opposite direction to the relative airflow during flight, so the airflow speed decreases."

"In this case, if the trajectory of the tennis ball is not carefully calculated, it will easily deviate from the course! This is the Magnus effect."

Bang.

After Renji's words fell, the tennis ball landed heavily on the court.

A clear mark appeared on the ground, but it was not in the court. The tennis ball happened to be out of bounds.

"Out of bounds, out of bounds, really out of bounds!"

"That's a lie. Is what that guy just said true?"

The people next to him stared blankly at Renji who was talking on the court, with doubts in his tone.

"call!"

Renji glanced behind him. The probability of the tennis ball going out of bounds just now was over 80%. But if there was the influence of the outside air, everything would be unknown. Fortunately, no accident happened. The tennis ball just came out of bounds.

"Senior, how did you do it!.～？"

Looking at Renji blankly, Kirihara stuck out his tongue and said in disbelief.

"Want to know?"

Lian Er glanced at the other party indifferently, and then asked

""Uh-huh."

Kirihara nodded quickly, as if he was curious about a baby, and Renji raised the corners of his mouth, revealing an unnoticeable smile.

"Read more, it’s all in the book, and you’ll probably be able to learn this next time you get an A in math!"

"...."

After hearing Renji's words, Kirihara's head was full of black lines!

Looking at the other party, I just felt that the soft senior student in the past was gradually heading towards the path of evil. He got an A in mathematics, which was difficult for him to pass mathematics. fundamental! impossible!...

Phew.

Outside the stadium, Nioh, who was watching the ball quietly, suddenly smiled, leaving the people around him confused.

"What's the matter?"

"nothing!"

Nioh shook his head. Having learned spoken English, of course he knew the conversation between the two on the court, so he couldn't help but laugh.

"Poof!"

He didn't answer the others, but took another look at Renji. He didn't expect that the great military advisor of Rikkai actually had such a dark side.

"The more gentle a person is, the more terrifying he is when he turns evil!"

Nioh suddenly thought of such a huge statement. He didn't seem to take it seriously at first, but now it feels quite reasonable.

(Fuji seems to be like this too, right?...）

"Hey, Nioh, do you hear what they are saying? Marui on the side looked at King Renin curiously and asked him.

King Ni shook his head and answered ambiguously,"Who knows?""...

Looking back to the court, the game between the two sides started again. The scene just now gradually became a microcosm. After seeing Renji's ability, Tachibana in the frontcourt did not dare to fight back unscrupulously.

But a lion that seems ready to explode at any time, looking for opportunities!

The situation on both sides became deadlocked for a while.

"game, Lihai University, 1-0."

"game, Lihai University, 2-0."

"game, Fudo Peak, 1-2."..

"game, Fudoho, 2-2."

The score also gradually increased, and the personnel on both sides were constantly familiar with each other's return ideas.

"If this continues, it will be an advantage for them, but their resilience is also quite strong. They can still persist under the attacks of Kirihara and the others!"

After taking a deep look at the game, Liu (Li Qian's) said to a few people, but his face was not anxious. The further you go in data tennis

, the better you can collect the opponent's data, so that you can often get it later in the game. Control the game, so you are not afraid of such a protracted battle

"Advantage?"

Sanada, who was at the front of the court, had curiosity in his eyes. He looked at Renji, who was reluctant to take action, and shook his head.

He said in a tone that everyone didn't understand.

"Not necessarily an advantage..." ps: After reading for two days, I feel a little uncomfortable after the exam. Don’t panic. It’s a small problem with failing the exam. There is an exam the day after tomorrow. I didn’t go to bed until early in the morning yesterday. Now I went to Qin to catch up on my sleep! _Please read the ununderlined version of the novel
