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

“Kirihara, haven’t you studied fluid mechanics, in normal return strike situations, the tennis ball moves in a straight line at a certain speed, and at this time, the air flow will only cause resistance to the tennis ball.”

After a pause, Renji looked at the opposite side, “However, the tennis ball rotates through friction. When the tennis ball rotates while flying in the air, it also drives the surrounding air flow to rotate.

On one side of the tennis ball, the air flow generated by rotation is in the same direction as the relative air flow in flight, so that the air flow speed is accelerated; On the other side, the air flow generated by rotation is in the opposite direction to the relative air flow in flight, and the air flow velocity is reduced. ”

In this way, if the trajectory of tennis balls is not carefully calculated, it is easy to deviate from the course! This is the Magnus effect. ”

bang

Renji’s voice fell, and the tennis ball landed heavily on the court,

A clear mark appeared above the ground, but not inside the court, and the tennis ball happened to be out of bounds.

“Out of bounds, out of bounds, really out of bounds!”

“Liar, that guy, is what you just said true?”

The person next to him looked at Lianji, who was talking on the court, with a questioning tone in his tone.

“Phew!”

Lian Er glanced at the back, the chance of tennis out of bounds just now was above eighty percent, but if there was the influence of the outside air, everything would be unknown, fortunately, there were no accidents, and tennis just came out of bounds.

“Senior, how did you do it!.~?”

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

“Want to know?”

Lian Er glanced at the other party without being salty, and then asked.

“Uh-huh”

Kirihara nodded quickly, looking curious about the baby, and the corners of Renji’s mouth rose, revealing an imperceptible smile.

“Read more, there are all in the books, the next time you get an A in math, you will probably be able to learn this!”

“….”

After Kirihara heard Renji’s words, his head was full of black lines!

Looking at each other, I only felt that the former soft senior also gradually walked to the road of black belly, and got an A in mathematics, which is difficult for him to pass mathematics.

Base!

No way!

…

Swoosh

Outside the stadium, Renwang, who had been watching the ball well, suddenly smiled, which made the people around him a little puzzled.

“What’s wrong?”

“Nothing!”

Renwang shook his head, having learned to speak, of course he knew the conversation between the two on the court, so he couldn’t help but laugh.

“Poof!”

Instead of answering the others, he glanced at Lian Er more, but he didn’t expect that the military master of Lihai University actually had such a dark side.

“The more gentle a person is, the more terrifying his belly will be!”

King Ren suddenly thought of such a huge statement, which seemed unimpressed at first, but now it feels quite reasonable.

(Probably so…) ）

“Hey, Renwang, did you hear what they were saying?” Marui on the side looked at King Rejin curiously and asked him.

And Renwang shook his head and replied ambiguously, “Who knows? ”

…

Looking back on the court, the game on both sides began again, and the scene just now gradually became a microcosm, and after seeing Renji’s ability, Tachibana in the front court did not dare to fight back unscrupulously.

It is a lion that seems to be ready to erupt at any time, looking for opportunities!

The situation on both sides actually reached a stalemate for a while.

“Game, Tachikai Dai, 1-0.”

“Game, Tachikai Dai, 2-0.”

“Game, Fudo Peak, 1-2.”

..

“Game, Fudo Peak, 2-2.”

The score is also gradually rising, and the personnel on both sides are constantly familiar with each other’s return ideas.

“In this way, it is an advantage for them, but their resilience is also quite strong, and they can actually hold out under the attack of the two of them!”

Taking a deep look at the game, Liu (Li Qian’s) Sheng said to several people, but his face was not in a hurry.

Data Tennis

The further back, the more you can collect the opponent’s data, so that you can often control the game in the later stages of the game, so such a protracted battle is not afraid.

“Advantage?”

Sanada, who was at the front of the court, looked at Renji, who was slow to make a move, with curiosity in his eyes, and shook his head.

He spoke in a tone that everyone didn’t understand.

“Not necessarily an advantage…”
