The Strongest Strategist in Prince of Tennis

Chapter 91 Sudden black belly

A pair of pupils shrank slightly, and Kirihaya couldn’t help but look at the tennis ball. The original tennis track was constantly deviating and flying away from the court.

“Kirihaya, haven’t you learned fluid mechanics? In a normal return attack, 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 at the opposite side, “However, friction makes the tennis ball spin. When the tennis ball rotates while flying while delaying, it will also drive the surrounding airflow to spin.

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

“In this case, if the trajectory of the tennis ball is not calculated, it is easy to deviate from the course! This is the Magnus effect.”

boom

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

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

“Out, out, really out!”

“It’s a lie, that guy, is it true that what you just said is true?”

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

“call!”

Renji glanced at the back. The chance of a tennis ball being out just now was over 80%, but if there is the influence of outside air, everything will be unknown. Fortunately, no accident happened. The tennis ball just came out.

“Senior, how did you do it! 々”?”

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

“Want to know?”

Renji glanced at the other person indifferently, and then asked.

“Uh-huh!!”

Kirihaya nodded quickly, looking like a curious baby. The corners of Renji’s mouth rose, revealing an unnoticeable smile.

“Read more, you will find it in the book. Next time you get a in math, you will probably be able to learn this!”

After hearing Renji’s words, Kirihaya was full of black lines!

Looking at the other party, I only feel that the gentle senior from the past has gradually moved towards a dark-bellied road. He got a in maths, which is difficult for him who is difficult and qualified in mathematics.

fundamental!

impossible!

Flutter

Outside the court, Nioh, who had been watching the ball carefully, suddenly smiled, making people around him puzzled.

“what’s wrong?”

“nothing!’

Nioh shook his head. Of course, he who has learned oral English knows the conversation between the two on court, so オ can’t help but laugh.

“Puff!”

He didn’t answer the others, but took another look at Renji. I didn’t expect Rikkai’s Strategist to have such a dark-bellied side.

“The gentler the person, the more terrifying the belly becomes darker!”

Nioh suddenly thought of such a huge remark. At first, it seemed disapproving, but now it feels quite reasonable.

(Fuji seems to be like this too)

“Hey, Nioh, do you hear what they are talking about?” Marui looked at King Reni curiously and asked him.

But Nioh shook his head and replied ambiguously, “Who knows?”

Looking back to the court, the match between the two sides began again. The scene just now gradually became a microcosm. 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 explode at any time, looking for opportunities!

The situation on both sides suddenly became stalemate.

“”/ game, Rikkai big, 1-0.”

“Game, Rikkai is big, 2-0.”

“Game, Fudomine, 1-2.”

“Game, Fudomine, 2-2.”

The score has gradually risen, and the personnel on both sides are constantly getting familiar with each other’s ideas of returning the ball.

“If this goes on, it will be an advantage for them, but their resilience is also very strong, and they can actually persist under the attack of Kirihaya and the others!”

Taking a deep look at the game, Liu Sheng (Li Qianhao) spoke to several people, but his expression was not worried.

Data tennis

The more you get to the back, the more you can collect the opponent’s data, so you can often control the match in the later stage of the match, so you are not afraid of such a protracted battle.

“Advantages?”

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

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

“Not necessarily an advantage”

ps: After reading the book for two days, I felt a little uncomfortable after the exam. I didn’t panic. I missed minor problems. I still have the exam the day after tomorrow. I went to bed in the early morning last night. Now I have to make up my sleep! Fang,
