The next day.
At the tennis club of Rikkai University Junior High School.
"Yawn..."
Masaharu Niou, who looked like he hadn't slept well, walked in listlessly while yawning.
"Good morning~!"
On the contrary, Hiroshi Yagyu was unusually energetic.
After the two people's eyes met.
The former couldn't help but reveal a guilty expression, and hurriedly got busy.
But I don't know what he was busy with.
"Huh?!"
"Why is Senior Yagyu so energetic?"
"I remember that the haunted house of Abei's family is not only scary, but also has the wailing of tennis ghosts!"
Looking at the two people from a distance, Kirihara Akaya muttered with a puzzled expression.
"The wailing of tennis ghosts..."
The Jackal Kuwabara didn't know what to say.
In the entire Rikkai University Junior High School Tennis Club, only Kirihara Akaya could say such a nonsensical ranking.
"There is something a little bit wrong."
"Whether it is Niou or Yagyu, their eyes are shining with an exceptionally bright light."
"It's like being reborn."
Pop!
As the bubbles burst, Marui Bunta made an intriguing guess.
"Compared to this."
"I think everyone should think about why Kitagawa specifically told everyone not to bring tennis rackets today."
Yagi Renji, who was busy writing and drawing on his notebook, raised his head with a smile and said meaningfully.
"It should be that."
"I'm really looking forward to it."
Yukimura Seiichi took off his coat and put it on the rest bench.
While doing warm-up exercises, he responded with interest.
"Yeah."
At this time.
Sanada Genichiro looked at Yukimura Seiichi with burning eyes and responded solemnly.
"Want to play a game?"
"Sanada~"
Slowly lowering his stretched arm, Yukimura Seiichi seemed to see through the other person's mind in an instant, and asked softly with confidence and tenderness.
"Although I've been eager to do it in my heart."
"But!"
"It's not time yet."
After taking a deep look at Yukimura Seiichi.
Sanada Genichiro walked aside and did warm-up exercises on his own.
"I'll wait for you."
With a soft smile, Yukimura Seiichi added seriously.
At this time.
The staff of the tennis club brought over several large wooden boxes.
Step!
The next moment.
Kitagawa walked over from a distance.
The smile on his face was particularly sunny.
And at this time.
Everyone's Kitagawa radar exploded instantly.
"Gurgle..."
Although there were already guesses.
But Kitagawa is a master at making things happen.
Before the truth is revealed, no one can guess the other party's true intention.
"Good morning, seniors."
When he walked to the two big wooden boxes, Beichuan smiled even more.
Clank!
Clank!
There was no dragging of the feet, and no suspense.
The staff opened it directly.
What came into view were several boxes of rackets or sticks of different colors.
From left to right, they were black iron, bronze, silver, gold, and emerald.
"Starting today, we will learn to use the sweet spot technique."
"Before, when we were at the Cliff of Heart, everyone not only roughly knew what the sweet spot technique was, but also witnessed the cross racket of the ghost senior."
"But in fact, the learning and application of the sweet spot technique is not so casual."
While speaking.
Beichuan directly took out a black iron stick with a slightly thick front end, like a paddle, from the box on the far left.
"This is the sweet spot bat."
"The black iron, bronze, and silver sweet spot bats correspond to the impact center, the first harmonic wave node, and the maximum elastic recovery point, respectively."
"This is mainly to make it easier and more intuitive for seniors to feel the changes brought about by the sweet spot."
After the explanation.
Beichuan put it down and turned to the fourth wooden box.
"What about this."
"It is called a sweet spot racket."
"Of course, I usually call this a fly swatter."
"Its main purpose is to further practice sweet spot hitting."
There is no excessive elaboration on this thing.
After putting it down, Beichuan walked directly to the last wooden box and took out a racket with only two strings from it.
That is the cross racket I have seen before.
"This cross racket is customized one-to-one with the rackets currently used by seniors."
"In other words."
"IfIf you can use desserts on this cross racket, then you can also use it when you pick up your own tennis racket. "
To be honest.
The practice and contact of regular desserts in super large tennis clubs are all carried out in this step-by-step manner.
As for the cross racket in the original book, it is a one-time solution, cost-saving and time-wasting method.
After all, a customized cross racket alone is not a small amount of expense.
After introducing the contents of the box.
The Rikkai University Affiliated Middle School still stood there and stared at Kitagawa.
Everyone looked like they wanted to kill or cut him casually.
"Don't be like this~"
"I didn't think about doing anything."
"Since everyone is so looking forward to it, let's do one."
"If anyone is still at the sweet spot bat stage before dusk today, congratulations, the Sea King is calling you."
"This time you need to swim from Kanagawa Port to Chiba City Port. "
"Don't worry about exhaustion or anything, the ship will follow you anytime and anywhere."
"Before tomorrow's dusk, whoever is still at the fly swatter stage, congratulations, you can go into the mountains for further study."
"Before the dusk of the day after tomorrow, whoever has not mastered the cross racket."
"Hehe..."
"By then, everyone can completely complete the achievement of going up to the sky, into the ground, and into the sea."
After a helpless sigh.
Kitagawa raised a playful smile and spoke softly.
After the voice fell.
Everyone was relieved.
"This is just right~"
Kirhara Akari couldn't help but smacked his lips and said, then he ran excitedly to the first wooden box and looked for the sweet hit bat customized for himself.
"Are there any grades for sweet hits?"
The next moment.
Yanagi Renji raised his hand and asked.
"Yes." ”
“From a scientific point of view, the sweet spot is the point on the racket face that can return more than 40% of the ball speed.”
“55% is the A point, 70% is the S point, 85% is the SS point, and 100% is the SSS point.”
“The A point is a regular and mature sweet spot for hitting the ball.”
“The S point can make the swing of the tennis ball undergo a qualitative change, and at this time it can be called a ball skill.”
“The SS point is a strengthening of the previous S point.”
“The SSS point is an even more evolved version.”
“In addition, the sweet spot can be used not only in offense, but also in defense.”
