Prince of Tennis: A new Hextech Crafting System is refreshed every week.

Kitahara Akira gazed indifferently at the world before him, everything around him clearly visible, as if he were observing this world from a higher dimension.

Those dark eyes seemed to see through everything, yet they held a certain...

A sense of alienation.

If Kitahara Akira only experienced slight emotional fluctuations when he was in the double-efficiency state, then now that he has entered the triple-efficiency state, he possesses absolute rationality and super intelligence that does not exist in the world, and he even has a vaguely inhuman feeling.

Thud! ...Thud! ...Thud! ...

He raised his hand.

Continuously toss the ball, swing the racket, and hit the ball!

The Three Winds attack technique, which he had just completed, was quickly refined with subtle adjustments, making it easier to use without reducing its power.

In fact, he could have learned more advanced power generation techniques and used them to create even more powerful skills.

However, he did not.

Because everything Kitahara Akira is doing right now is within the limits that he can handle in his normal state.

after all.

His current omnipotence is only temporary.

If he cannot understand, master, or apply the skills in actual combat a week later, then even if he develops and creates many powerful ball techniques at this moment, it will be of no use.

Another hour later.

Thud! Thud! Thud! ...

A tennis ball flies back and forth between the green wall and Kitahara Akira's racket.

When you don't have a practice partner, a wall is the best opponent.

Kitahara Akira's original plan did not include supplementing the basic content. He had assigned this task to himself a week later. However, after entering triple efficiency, he chose to complete it ahead of schedule.

Only a few hours had passed since the data on all aspects of our situation were determined that morning.

Kitahara Akira had completely changed his appearance.

Watching the trajectory of the tennis ball as it bounced back, he steadily raised his racket, accurately caught the landing point, and smoothly and effortlessly returned it.

The brain quickly analyzed the impact of the shot, and lines of corresponding data seemed to appear in the eyes.

In just a few hours.

Kitahara Akira quickly transformed from a relatively weak player who barely reached the level of the Metropolitan Tournament into a top-tier player at the Metropolitan Tournament level.

No longer needing to rely on special tactics to play to their strengths and avoid their weaknesses, they can directly compete against other top-level players.

And there is still a victory.

Even the physical fitness, speed, and strength that require the most time to accumulate have reached the average level of major competitions thanks to the three-fold increase in efficiency.

Kitahara Akira could use one hour as three hours, and those three hours were equivalent to twelve hours for others.

But in reality...

Who can complete twelve hours of high-intensity training in one go?

Including the time spent forgetting, getting back into the zone, and recovering, Kitahara Akira's three hours were almost equivalent to a week for others, or even more.

Three times the efficiency, far more powerful than imagined.

"Next, let's go to the Hisumikan Dojo." Kitahara Akira's eyes gleamed.

In tennis.

He had already improved to the limit he could accept a week later. Going to the dojo was to try to apply his knowledge to tennis and add more weapons to his tennis skills through kendo.

......

Hisameikan Dojo.

Genichiro Sanada is fighting against an imagined "enemy".

"Swift as the wind!"

He held the sword with both hands, starting from a mid-range stance, his arms instantly becoming a blur as the bamboo sword slashed out at a speed imperceptible to the naked eye.

Just as the tip of the knife was about to touch the ground, he quickly stepped back and assumed a lower stance.

The offensive stance instantly turned into a defensive one.

Xu Rulin.

At the same time, the tip of the blade flicks upwards, embodying the concept of "the rear first." Sanada imagines his opponent slashing, which is precisely deflected by his own blade, and as he completes the defense, the tip of the blade almost imperceptibly grazes the opponent's neck.

Immediately afterwards, another 'enemy' came from the side.

"Aggression burns like fire!"

Sanada steps forward with his right foot, assuming the upper stance of the Fire Formation!

Then he suddenly jumped, spun his body in the air, and used the kinetic energy generated by the rotation to grip the bamboo knife tightly with both hands and chop it down with all his might.

Tear!

Without anyone noticing, the bamboo knife seemed to scorch wherever it went, the air distorted, and the bamboo knife seemed to have cut out a trail of flames.

After that one devastating strike.

Sanada immediately returned to his original position, left foot forward, right foot back, sword upright, and an unshakeable aura suddenly rose up like a mountain.

"Immovable as a mountain!"

Wind, Forest, Fire, Mountain!

Sanada learned the four great principles from military strategy and found the corresponding four stances in swordsmanship. He integrated these principles with swordsmanship and applied them flexibly to tennis.

It was the year that the "Wind, Forest, Fire, Mountain" playing style was first created.

He has just come down from the mountain.

Then he encountered Tezuka Kunimitsu, and lost both games 1-6 and 0-6.

This was partly because the "Wind, Forest, Fire, Mountain" formation was not yet fully mature at that time.

But in the last two years.

Even though he had mastered the "Wind, Forest, Fire, Mountain" technique, he still couldn't help but recall his match against Tezuka Kunimitsu.

Facing the Tezuka Zone, which controls all the spin, and the shots that embody the spirit of countless trials and tribulations, Sanada still had no confidence in winning.

"Not enough!"

Sanada roared and raised his bamboo sword, slashing down fiercely and relentlessly.

Swish!Swish!Swish!

The bamboo sword was swung out again and again with a whooshing sound.

Sanada, however, could not find that moment of inspiration and did not know how to break through Tezuka's powerful, time-tested techniques.

As long as that one move is available.

No matter how powerful the wind, forest, fire, and mountain winds are, Tezuka can return the tennis ball with double the power, spin, and speed.

In the Tezuka Ward, facing countless trials and tribulations.

His tennis.

It has lost its meaning of existence.

At this moment, Sanada was extremely eager to find a way to defeat Tezuka and to make tennis, which had been stagnant for a long time, stronger again.

This is not just about overcoming one's inner obsession.

This is also in order to achieve the great feat of winning the national championship for the third consecutive time next year.

"I want to become stronger, to hand over the three-peat championship trophy to Yukimura, and to fulfill the wish we made together. That way, even if Yukimura..."

Snapped!

Before Sanada could fully process what he was thinking, he slapped himself across the cheek, turning it bright red instantly.

"Yukimura will return to the court."

The slap instantly calmed Sanada down.

He still couldn't figure out how to take tennis to the next level.

Swish!

......

Swish!

......

Just then, a rhythmic sound of swords swinging not far from the training ground caught Sanada's attention.

He turned his head to look.

A boy with short, black hair was practicing his breathing technique.
