I'm proving the fairy king in Naruto

"Mr. Kakuzu, after my body has been tempered, my entire body has been improved from the inside out."

"According to Mr. Kakuzu, the chunin tempered his body with chakra three times."

"The Jonin has tempered his body about ten times."

"If there is such a huge improvement every time, it stands to reason that things like kunai should not be able to hurt jounin?"

Genshinji rested for a while, sat in front of Kakuzu and told all the questions he had about yesterday's practice.

"Improvement in physical fitness is not as scary as you think."

"Your body was originally in the growth stage. Your original body was too weak, so you felt like this."

"After tempering the body with chakra for the first time, the entire body will be improved by about [-]% in all aspects. Whether it is the toughness of the skin or the hardness of the bones, even your vitality will be improved by this much."

"But after the second tempering, you will only improve by about [-]%."

"In the third tempering, there is only about a [-]% improvement, and after that, there is only a [-]% improvement."

"Even a Jonin's body is only about five times stronger than an ordinary person's."

"This level is far from being invulnerable to swords. What's more, who told you that kunai is made of ordinary metal?"

"The kunai in the hands of ninjas are made of a special kind of iron ore. It is not too difficult to break through the ninja's body."

After hearing what Yuanshenji said, Kakuzu didn't hide anything and told Yuanshenji truthfully.

"A Jonin's physical fitness is only five times that of a normal person?"

"Every time you temper your body, will it weaken?"

Yuanshenji frowned. He thought that every time he tempered his body with chakra, his body would be improved five times, but now it seems that he is the difference.

"Five times the limit of ordinary people, do you know what this means?"

"A normal person's strength is about three hundred kilograms, and a jounin can easily lift about fifteen hundred kilograms."

"A normal person can reach 12 meters in 100 seconds, but a jounin can cover a distance of [-] meters in just two or three seconds!"

"Do you think such a jounin is weak?"

Kakuzu glanced sideways at the young daimyo in front of him. As he got along with Genshenji, he found something that he had never had before.This daimyo can be regarded as his disciple!

Kakuzu himself never thought that people like him would one day have disciples.

"I was wrong. In addition to those, the vitality of Jonin is about five times that of normal people. Compared with normal people in the ninja world, ninjas are definitely monsters even if they don't have chakra."

Yuanshenji was silent for a long time, and finally nodded seriously to Kakuzu. Five times the limit of ordinary people, this is not bad.

It's just that he brought the devastating scenes he saw in anime in his previous life to jounin, and that's why he felt that jounin was weak.

But this also solved another doubt in his mind.

When he watched Naruto in his previous life, he felt that ninjas were not physically strong, and even Madara Six Paths could have his heart ripped out by Black Zetsu.

But the speed of ninjas is really fast, and now it seems that this is an extremely normal thing.

"Also, this is just physical fitness. Ninjas are not samurai. Chakra is the basis for ninjas to survive!"

"If all the jounin's chakra is released, the water ninja can submerge everything within a radius of 600 meters."

"Besides the warriors of the Iron Kingdom, the only people who care about physical strength are the people from Kumogakure!"

Kakuzu thought for a moment and added another sentence.Ninja's physical skills are very important, but ninjas do not only rely on physical skills to fight, chakra is never a decoration.

"I understand. My thoughts are those of a traditional warrior. I will pay more attention to this in the future."

After listening to Kakuzu's words, Genshenji nodded extremely seriously.

"Mr. Kakuzu, there is another question. Chakra is a combination of physical energy and mental energy. If you use ninjutsu, in addition to losing physical energy, won't it also consume mental energy?"

Yuan Shenji solved the first doubt in his mind and threw out his second doubt.

"this problem……"

"I have not considered this issue. Not only me, but many people in the ninja world have not considered this issue."

"We are just tools for killing people. No one cares about the energy consumed by chakra. If you ask me about this, you are asking the wrong person."

Kakuzu looked at the Source God Machine in surprise. He frowned and thought for a while, but finally gave the Source God Machine an answer that made him slightly disappointed.

"But even if mental energy is lost, it should be replenished automatically, right?"

"In all my years in the ninja world, I have never seen anyone become abnormal because of too many ninjutsu?"

"No, it's not normal..."

“Not normal!!!”

"Is that so?"

"When chakra is used too much, mental energy will indeed be lost. The most intuitive manifestation is that there are too many abnormal people in the ninja world!"

"All ninjas are sick, and all ninjas are mentally abnormal to some extent!"

Kakuzu's expression was still a little indifferent at first, but after a while, he thought of something again, muttered to himself, and his expression began to change crazily.

Not only Kakudu thought of it, but Source God Machine also thought of it.

Excessive use of chakra will deplete mental energy, and excessive depletion of mental energy will cause some people to become extremely abnormal.Take Senju Hashirama and Uchiha Madara, who brought peace to the troubled times, for example. Who dares to say that these two people have normal minds?

"Damn!"

"This damn world, it turns out that everything is rooted in Chakra!"

The expression on Kakuzu's face changed crazily, and he couldn't help but feel intense murderous intent. He didn't know who this murderous intent was aimed at. Maybe it was against the world, or maybe it was against the Six Paths Sage?

Yuanshenji felt the surging killing intent and felt the hairs on his back stand up.

There was never another moment when he realized the flaws of Chakra so clearly. Otsutsuki Motojie was right, Chakra was a flawed power from the beginning to the end.

Originally, Yuan Shenji only thought that the flaw was in the nature of chakra, but now it seems that this chakra can also corrode the soul!

To put it bluntly, as long as there are still people using chakra, the ninja world will never be truly peaceful. After all, too much spiritual energy is wasted, and there will always be some madmen!

Among them, the Uchiha family is the most obvious. Who made his Sharingan directly related to the Yin attribute chakra?
