The Invincible Life of Kasugano Yu

Noticing the way Kasugano Yu looked at her, Nezuko tilted her head, still holding the bamboo tube in her mouth.

"If your sister became like this in these two days, I can make your sister change back to a human directly... Judging from the situation, it has been two or three years, right?"

"Well, Nezuko became a ghost before I trained to become a swordsman of the Demon Slayer Team, and then she fell asleep for two years during my training before waking up."

"No wonder." Kasugano Yu nodded understandingly.

"Tanjiro, let's start the test. After completing the test here, you can become a hero of the Hero Association. I think you should be able to pass easily with your physical fitness. As for your sister, just watch from the side. As long as you don't go out There will be no problem if it is exposed to sunlight." Yuu Kasugano took Tanjiro Kamado and took him to conduct various tests in person.

Tanjirou Kamado's physical fitness can only be said to be much stronger than that of ordinary people, but if it is said to be made of steel and iron, that is impossible. Tanjiro Kamado's body is very fragile. After all, as long as ordinary humans do not undergo any mutations, they will never It is impossible to train to be invulnerable.

Kamado Tanjiro practiced a method called "Comprehensive Breathing Method", which allows human beings to use ordinary flesh and blood to fight against aliens mutated by Kimai Tsuji's blood.

Kasugano heard Tanjiro Kamado say that this breathing method is mainly used to strengthen the heart and lungs and improve physical ability.

In this "Comprehensive Breathing Method", the "breathing of the sun" is the ancestor, from which "breathing of water", "breathing of thunder", "breathing of flame", "breathing of rock", "breathing of wind" are derived. The breath' five genres.

Based on these five major genres, subsequent talented people have created various new genres with characteristics.

The whole concentration breathing method is a method that ordinary people can also learn.

Kasugano Yuu thinks this kind of method is a bit interesting. He is learning the tricks of these methods very quickly now, so he directly drags Kamado Tanjiro, who has completed the hero test and has become a B-level hero, to an empty training ground.

"Yu... Brother Yu, are you serious? With your strength, you still need to learn this..." Tanjiro Kamado was the most puzzled.

In his opinion, a special superpower like Kasugano Yuu shouldn't need to learn such an ordinary method.

"I just want to experience it, I think it's very interesting, Tanjiro, you tell me how to operate it, just give me a general introduction..."

"That's it." Kamado Tanjiro pondered slightly, he squeezed his chin, and said after careful consideration: "Then let me briefly talk about it. I learned it after two years of practice. The experience is absolutely sufficient. Generally speaking, it is strengthened by breathing and holding your breath." Cardiopulmonary function, in this way, the blood can absorb a large amount of oxygen, which can greatly increase the physical ability in an instant..."

After Kamado Tanjirou roughly finished speaking, he demonstrated a few more sword moves, each of which had blue and white water jumping. After the demonstration, he wiped the sweat from his forehead and said, "That's probably all."

Finding that Kasugano Yuu didn't speak, Kamado Tanjiro looked at him strangely, and then, Kamado Tanjiro froze there.

"This state..." Kamado Tanjiro was very familiar with it, it was the state where he had mastered the method of breathing in the whole concentration.

"No way, you learned it so quickly?" Kamado Tanjiro felt incredible.

Even Nezuko, whose intelligence was only at the level of a child, couldn't help but widen her pink eyes.

"Comprehensive breathing·breathing of water." Kasugano Yuu opened his eyes.

He opened his mouth slightly, took a deep breath, and immediately, Kasuga Yeyu waved his arm, and the entire training ground was instantly covered by sea-like waves.

The blue sea waves rolled continuously around, and the wind was strong.

"Exit."

But in the next second, everything returned to calm, and the clear dripping sound passed by, as if nothing happened just now.

Seeing such a vast wave of sea and sky disappearing gradually, Kamado Tanjiro was stunned, his eyes almost shrinking to the size of beans, which was simply beyond his life experience.

What kind of monster is this? Why can I learn things so quickly.

"It feels pretty good..." Kasugano Yuu narrowed his eyes slightly, he thought of the way of using this method.

This kind of breathing method can be used with pure physical body, and it is obviously effective against the attacks of evil objects, and after becoming a Kamen Rider, Kasugano Yu can also add the power of full concentration of breathing to his swaying moves.

To put it simply, it's like playing a game and being brushed with an extra layer of attack BUFF by a supporting character.

However, this attack buff is a special attack buff against undead and evil spirits.

"It's an unexpected gain for me..." Kasugano Yu looked at Tanjirou Kamado who was completely dumbfounded beside him, he coughed lightly and said with a smile: "I learned it, and it feels good, Tanjirou, thank you. "

"... Brother Yu, you are really... a genius..." After a long time, Zamon Tanjiro said this bitterly.

He didn't think that he was just talking about it in general. It was impossible for the other party to learn without systematic study. After all, if he really wanted to learn, he could go to his master Linlong Zuojinci.

In order to learn swordsmanship and concentrated breathing, Tanjiro has been wandering on the verge of death for two years... I thought I had learned it very quickly, but now I see Kasugano Yuu, and I know that people compare to others, and they are maddened to death.

But Tanjiro Kamado also thought very clearly, the Kasugano Yu in front of him is after all the strongest in the world, thinking about it like this, it doesn't seem uncomfortable.

"Tanjiro, if you don't have anywhere to go today, you can rest and stay here. There are also staff here to help, and they can also provide a variety of delicacies, which is no less than that of a five-star hotel."

"I was wondering where I should live before, Brother Yu, thank you for your help." Zamon Tanjiro bowed slightly.

Nezuko next to her blinked her eyes. She imitated the example and bowed down with Kamado Tanjiro.

"Your sister is very cute." Kasugano Yu couldn't stop laughing.

"By the way, can you let me check your sister, maybe I can cure her."

"What?!" Tanjiro screamed, and then excitedly said: "How do we check?"

"I'll just touch her head and feel her physical condition a little bit."

"If that's all it is, then there's no problem." Tanjiro said hastily.

The arm was gently placed on Nezuko's small head, and the perception in the body spread. After a while, Kasugano Yu said: "This situation should be able to recover, but I have no way to do it yet..."

Kasugano Yu can actually try to use some of the skill beams after becoming Gauss, or Tiga Ultraman's cell conversion beam to restore Nezuko's body, but even Kasugano Yu is not sure, Ultraman's skills can deal with this Is it possible to see a creature that is afraid of the sun?

You must know that aliens like Nezuko will dissipate and die when they touch the sun directly. How terrifying is the light energy of Ultraman?There's nothing wrong with calling it a movable sun.

This is one of the reasons why he wasn't sure if he could bring Nezuko back.

It would be even easier if he could become the king of the devil at will, and it would be easy to turn back the time of Nezuko's body directly.
