Blue Prison, I, Kirara Ryosuke, get the Breathing of Thunder at the beginning

"You are, Kira Ryosuke?"

Aida Katsutora's eyebrows twitched slightly. He didn't expect that the famous local football star would come here.

After Reiko Aida told her father about the situation, the latter's expression relaxed slightly.

"I see. Then I'll leave it to you, Reiko, to take full responsibility."

Aida Katsuyori looked at Kira Ryosuke, sized him up, and nodded.

“You can use all the equipment in the gym.”

"Thank you so much."

Kirara Ryosuke nodded at the other party.

"Then Ryosuke, come with me."

Reiko Aida quickly brought Kira Ryosuke to a corner of the gym, and took out a pen and paper from the side. While observing the opponent's body and analyzing the opponent's values, her right hand holding the pen wrote something quickly on the paper, like a machine.

At this time, Reiko Aida was completely immersed in her work, working meticulously, and it seemed that nothing happening around her could distract her attention.

In a few minutes, a piece of white paper was filled with words. Aida Reiko finally put down her pen and focused her eyes on Kira Ryosuke's face:

"Okay, the plan is almost done. Ryosuke, can you first tell me in which areas do you think you need to improve?"

"In terms of physical strength and stamina."

While speaking, Kira Ryosuke subconsciously turned his head to look at his right leg.

"Yes, this is a very important link, but it is far more than that. As I said before, although your physical fitness and training level are at a very good level among high school players, I think you still have room for improvement. The training method of your high school team should be very traditional, but it is not suitable for you, because what you need is more intense and professional training, because I think you should prepare for a broader professional career in the future."

Aida Reiko paused, as if she had thought of something.

"You're working so hard because the national competition is coming up soon!"

"Indeed, but there is a more important reason. I want to prepare for it."

Kira Ryosuke then told everyone that he had received an invitation from the Blue Prison. After all, it was not a secret.

"There will be a special closed training camp at that time... I am really curious about the content... But you are preparing to train crazily during this period in order to ensure that you are in better condition during the training camp."

"Ah."

Kirara Ryosuke answered very seriously,

"Because I feel that there are probably top players from all over the country participating in this training camp, and I don't want to lose to them."

Although Kira Ryosuke is not very interested in football now, he will do his best in anything he regards as a goal.

Perhaps, this was the stubbornness that came with being a cartoonist.

Aida Reiko did not answer immediately, but looked into Kirara Ryosuke's eyes. After confirming that he was serious and determined, she smiled brightly and handed him the list she had just written.

"Then you must work hard! But I have to tell you first, you can't be careless in training. I am a very strict person. Even if you are a local star, I will not indulge you."

"Don't worry, I'll follow Coach Lizi's arrangements."

Kirara Ryosuke responded jokingly.

"Then let's get started."

......

After some preparation, Kira Ryosuke began practicing according to the practice list arranged by Aida Reiko.

First is the core strength part. The so-called "core" refers to the middle link of the human body, the area below the shoulder joint and above the hip joint, including the pelvis. The core muscle group is responsible for stabilizing the center of gravity, transmitting force, etc. It is the main link in the overall force, and plays a pivotal role in the activities and force of the upper and lower limbs. A strong core muscle group plays a stabilizing and supporting role in body posture, sports skills and special technical movements during exercise.

Core strength is arguably the most important part of an athlete.

The first is the ordinary plank, which is very simple for Kira Ryosuke, but the difficulty soon increases. Dynamic plank, alternating lateral raises, lateral hip raises... These movements do not look difficult, but doing a certain number in a short period of time requires sufficient strength.

The training program that Reiko Aida arranged for Kira Ryosuke is very intense and very intensive. Since Kira Ryosuke has shown his determination, there is no possibility that she will relax at all.

Chapter 6: This is a realm beyond genius!

".....Ninety-eight...Ninety-nine...One hundred!"

Soon Kira Ryosuke completed his seventh set of training.

After finishing, he heard the voice from the system in his ears.

[Congratulations! Obtained Competitive Points: 3]

For every hour of physical exercise, Kira Ryosuke can obtain a certain amount of competitive points.

Such high-intensity training was very strenuous for Kira Ryosuke. The training intensity in school was far less than it is now, but he still gritted his teeth and persevered.

There is only one week left, and he must make a breakthrough.

Once you make up your mind, you must give it your all.

Seeing Kira Ryosuke practicing so hard, Reiko Aida nodded with satisfaction. At the same time, she found her father, Katsuya Aida, and asked him to prepare some specific ingredients for Kira Ryosuke.

Football players have very high physical requirements, so they need to consume a lot of carbohydrates to replenish energy. Fruit bread can be quickly digested by the human body and is a more suitable choice. At the same time, they also need lean meat to supplement protein, potassium-containing foods such as bananas to maintain the balance of electrolytes in the body, and alkaline foods such as soy products or dairy products to eliminate fatigue.

“These things together are not cheap.”

Aida Katsuyori said to his daughter.

"When the time comes, just deduct it from his advertising fees. After all, his advertising fees are much more expensive than his tuition fees."

Reiko Aida said with a smile, and turned her head to look at the gate. The gym was open and people were pouring in one after another.

"Wait, is that person Kira Ryosuke?"

"The one who won the district championship yesterday! He's known as the gem of the football world!"

"He's actually working out in this gym too! Boss, I want to renew my membership card!"

......

At dusk, the sun slowly sets, and the sky is illuminated red by the sunset, like a burning flame.

"Thank you for your hard work. I'll go back first! See you tomorrow!"

Kira Ryosuke waved to Aida Reiko and left the gym.

"What a determined young man, just like me in the past."

Aida Katsuyori said expressionlessly as he looked at Kira Ryosuke's slowly leaving back.

"He is indeed a very good player. He is a little famous but he is not arrogant at all. Moreover, he has no complaints in the face of such high-intensity training. Even adults may not be able to endure this."

Aida Reiko replied.

"Oh, to be honest, I didn't expect you to bring a boy back this morning. I thought you found a boyfriend and I almost wanted to kill him."

There was no joking expression on Aida Katsutora's face. He patted his pocket and took out a fruit knife hidden inside.

"what are you talking about!!!"

Reiko Aida's face turned red, and she reached out and punched her father on the chin.

.....

In the evening, Kira Ryosuke returned home and had dinner in the gym. He lay down for a while after returning home. The fatigue from a day of training had almost eased.

Although the training list formulated by Reiko Aida is very intense, it is indeed the fastest way to make up for one's own weaknesses in the short term. This is an effect that cannot be achieved by practicing blindly by oneself or practicing with the team.

He opened his system menu and found that his competitive points had reached the daily cap of 10 points.

"There are still seven days left, and I can earn a total of 80 competitive points. It will take some time to unlock the Second Form. Before that, if I practice the Full Concentration Breathing and the First Form to the highest level of proficiency, I will need competitive points to upgrade. There is still a long way to go."

After resting for a while, Kira Ryosuke didn't plan to sit around and went out for a jog around the street where his home was.

He has already obtained all the competitive points through training today, and even if he performs other exercises next, he will not be able to obtain more competitive points. However, Kira Ryosuke continues to practice not to obtain competitive points, but to exercise his body.

As his skill proficiency and his own physical strength improve, he should be able to use the system's capabilities more freely in the future.

He practices ball skills during the day and exercises in the afternoon, and now Kira Ryosuke is preparing to practice breathing techniques.

Jogging is different from sprinting. It is an aerobic exercise that can improve the body's cardiopulmonary function and enhance oxygen supply - this is what breathing techniques require.

Kira Ryosuke jogged in the night, rhythmically adjusting his breathing rate to remind himself of the feeling of using breathing techniques during the day.

Using breathing techniques can give a person powerful explosive power in an instant. In the world of Demon Slayer: Kimetsu no Yaiba, the swordsmen of the Demon Slayer Corps are able to use the Nichirin Sword to fight against demons who have power far beyond that of humans because of this.

And swordsmen with even stronger strength can even maintain a state of full-concentration breathing all the time, using full-concentration breathing around the clock to dramatically improve their physical fitness.

However, Kira Ryosuke is still far from being able to achieve this level. He can't even maintain full concentration breathing for a very long time, basically just a short moment - but precisely because of this, he knows that he still needs more practice.

He recalled the feeling of breathing during the day and quietly changed the frequency of his breathing.

Focus on breathing!

Kira Ryosuke felt that the oxygen rushing into his lungs was instantly converted into energy, filling his entire body, and the weight of his body seemed to disappear.

The state of fully concentrated breathing can greatly enhance human functions, but Kira Ryosuke has not yet fully mastered this ability and can only maintain it for a moment. The second use also requires a certain amount of rest time.

While running, Kira Ryosuke tried hard to increase the frequency of using full concentration breathing.

On the fifth attempt to enter the state of full concentration breathing, a new method came into Kira Ryosuke's mind.

A flash of thunder!

Kira Ryosuke used his move again, and the power that had just flowed through his body instantly poured into his legs, and then he released the power and kicked out with force!

At this moment, Kira Ryosuke seemed to feel that he was flying.

Soon, the familiar and obvious feeling of soreness came again, and this time it was in both legs. However, compared to during the day, Kira Ryosuke seemed to feel much better. He leaned against the wall, breathing heavily, and followed the method taught by Aida Reiko during the day to relieve the pain. At the same time, he turned his head to look in the direction he had just come from.

In just a moment, he actually jumped over a distance of several meters, which his original incarnation could not do.

That is a realm beyond the reach of genius.

Chapter 2: Upgrade! Full Concentration Breathing Level

"Just like during the day, there is no problem with intermittent use, but each time I fully concentrate on breathing, I can only last for a moment."

"Thunderbolt Flash seems to be an ability that instantly increases the explosiveness of the legs. It can be used not only for shooting, but also for breakthrough runs. Combined with full-concentration breathing, it can bring very exaggerated effects. This will affect both legs. Although the soreness is less than shooting, it can only be used at critical moments."

"And even if I'm not in a state of full concentration breathing, this skill has a wide range of uses. I won't be able to maintain the use of breathing techniques for a long time in the short term, so I must master the basic skills thoroughly..."

Kira Ryosuke wiped the sweat from his forehead. Although the soreness had not completely disappeared, he did not hate the feeling.

The proficiency of fully concentrated breathing is also slowly improving.

.....

Every day that followed, Kira Ryosuke would go to the stadium to train before the sun came out.

Because he created too much noise on the first day, he did not use Thunderbolt Flash in the full concentration state again on the court, but practiced the skill under normal conditions.

Another most important point is that a game lasts more than ninety minutes, and Kira Ryosuke knows the limit of his current ability. Even if he is praised as a genius or a treasure, it is far from enough. The full concentration breathing state can temporarily enhance his physical fitness, but the time to maintain the full concentration breathing state in a game is limited, and once the Thunderbolt Flash is used in this state, this move cannot be used again in a short period of time, so the 'basic version' of the Thunderbolt Flash becomes more important.

The accuracy of shooting with the Thunderbolt Flash and the speed of dribbling the ball are all things that Kira Ryosuke needs to practice.

At this time every day, Reiko Aida would also come to the stadium for morning exercises. This was Kira Ryosuke's exclusive ball skills training. She would not disturb him, and at most would help him do some warm-up exercises.

However, sometimes when Reiko Aida was doing morning exercises, she couldn't help but stare at Kira Ryosuke practicing basketball. The skills and speed displayed by the opponent were beyond her imagination.

Of course, she had to admit that Kira Ryosuke had a very handsome face.

After the sun rose completely, more and more people came into the venue. Reiko Aida took Kira Ryosuke to the gym and started the most important physical training. Kira Ryosuke basically spent the entire day here, and also had lunch and dinner in the gym.

At night, Kira Ryosuke continued to practice the use of breathing techniques, jogging outside, adjusting his breathing, and trying to use the explosive power of Thunderbolt in running.

He even bought a gourd, just like the characters in the original Demon Slayer, and blew into it every day to exercise his lung capacity.

Before I knew it, a week had passed.

Time passed quickly, and soon it was the last day before reporting to the Football Association.

It was already evening, and Kira Ryosuke had just finished his last day of physical training and was washing off the sweat in the gym's bathroom.

Feeling the gentle flow of water washing away today's fatigue and sweat, Kira Ryosuke opened his system interface.

[Competitive. Thunder Breath. Full concentration LV1 proficiency 100%, upgradeable, 50 competitive points]

[Competitive. Thunder Breathing Type 1. Thunderbolt Flash LV100 Proficiency 50%, Upgradable: Competitive Points]

[Current competitive points: 80]

After practicing for a period of time, Kira Ryosuke finally mastered the full proficiency of the Full Concentration Breathing Method and Thunderbolt Flash today. He practices more than 1000 shots every morning and insists on practicing the breathing method at night.
