"Mr. Kakudu, after my body has been tempered once, my body has been improved from the inside out."

"According to Mr. Kakuto, Nakashinobi has tempered his body with chakra three times."

"Shangnin has tempered his body about ten times."

"If there is such a huge improvement every time, it stands to reason that such a thing as kunai should not be able to hurt Shangnin, right?"

Yuan Shenji rested for a while, sat in front of Jiaodu, and said all the questions he had about his cultivation yesterday.

"The improvement of physical fitness is not as scary as you think."

"Your body is in the growth period, and your original body is too weak, that's why you feel this way."

"After refining your body with chakra for the first time, your entire body will probably increase by about fifty percent in all directions, whether it is the toughness of your skin or the hardness of your bones, even your vitality will be increased so much."

"But the second tempering, you will only have about a thirty percent improvement."

"In the third tempering, there is only about 20% of the improvement, and there is only 10% of the improvement in the future."

"Even if it's Shangnin, the physical fitness is only about five times that of ordinary people."

"At this level, it's far from the point where the sword is hard to hurt, not to mention, who told you that kunai is made of ordinary metal?"

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

After listening to the words of the source god, the horn did not hide anything, so he told the source god machine truthfully.

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

"Every time you temper your body, will there be a weakening?"

Yuan Shenji frowned, he still thought that every time he used Chakra to refine his body, he would only improve fivefold, but now it seemed that he was different.

"Five-fold human limit, do you know what that means?"

"The strength of a normal person is about three hundred catties, and Shangnin can easily lift a weight of about fifteen hundred catties."

"The speed of a normal person is 100 meters in 12 seconds, but Shangnin can cross a distance of 100 meters in just two or three seconds!"

"Do you think it's weak like this?"

Kakudu squinted at the young daimyo in front of him, and as he got along with Genjin Ji, he had found something he hadn't had before. This daimyo can be regarded as his own disciple!

Kakudu himself didn't expect that a person like himself would one day have a disciple.

"It's that I think it's bad, in addition to those, the vitality of Shangninja is also about five times that of a normal person. Compared to normal people in the ninja world, ninjas are definitely monsters even if they don't have chakra. ”

Yuan Shenji was silent for a long time, and finally nodded seriously at the corner, five times the limit of ordinary people, this is not bad.

It's just that he brought the devastating scenes he saw in the anime in his previous life into Shangnin, which made him feel weak.

But this also solved another doubt in his heart.

When he watched the Hokage in his previous life, he felt that the ninja's body was not strong, and even the six spots could be taken out by the black Jedi.

But the speed of the ninja is really fast, and now it seems that this is a very normal thing.

"Also, it's just physical fitness, ninjas are not samurai, chakra is the foundation of ninja survival!"

"If all the Chakras of the Upper Ninja are released, the Water Escape Ninja can drown everything within a radius of five or six hundred meters."

"Those who care about the strength of their bodies, in addition to the warriors of the Iron Country, are only the people from Yunyin's side!"

Jiaodu thought about it and added another sentence. Ninja's physical skills are very important, but ninjas don't just rely on physical skills to fight, and chakra can never be an ornament.

"I see, my mind is that of a traditional samurai, and I will pay more attention to this in the future."

After listening to Jiaodu's words, Yuan Shenji nodded very seriously.

"Mr. Kakuto, there is another question, chakra is a combination of physical energy and spiritual energy, if you perform ninjutsu, in addition to the loss of physical energy, will it not consume spiritual energy?"

Yuan Shenji solved the first doubt in his heart, and threw out his second question.

"The question ......"

"I haven't thought about this issue, not only me, but many people in the ninja world haven't thought about it."

"We're just tools for killing, no one cares if the chakra drains that energy, if you ask me, you're asking the wrong person."

Jiaodu looked at the Yuan Shenji in some surprise, he frowned and thought for a while, and finally just gave the Yuan Shenji an answer that made him slightly disappointed.

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

"I've been in the ninja world for so many years, and I haven't seen anyone who has become abnormal because they have used too many ninjutsu?"

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

"Not quite !!"

"Is that so?"

"After using Chakra too much, it will indeed lose spiritual energy, and the most intuitive manifestation is that there are too many abnormal people in the ninja world!"

"All ninjas are sick, and all ninjas are more or less mentally abnormal!"

Jiaodu's face was originally a little indifferent, but after a while, he thought of something, muttered to himself, and his face began to change wildly.

Not only did the horns think of it, but the source god machine also thought of it.

If you use too much chakra, you will lose your spiritual energy, and if you use too much spiritual energy, it will cause some people to become extremely abnormal. Take Senju Tsuruma and Madara Uchiha who pacified the troubled times, who dares to say that these two people are in normal minds?

"Damn it!"

"This damn world, it turns out that the root of everything is in Chakra!"

Jiaodu's expression on his face changed wildly, and his body involuntarily carried a very rich killing intent, and he didn't know who this killing intent was aimed at, maybe it was aimed at this world, maybe it was aimed at the six immortals?

Yuan Shenji felt this surging killing intent, and only felt that the hairs on his back stood up in bursts.

There was never a moment when he recognized the flaws of Chakra so clearly, and what the Otsuki family said was not wrong, Chakra was a flawed force from beginning to end.

Originally, the Source God Machine only thought that this defect was in the nature of Chakra, but now it seems that this Chakra will also corrode the soul!

To put it mildly, as long as there are still people who use chakra, the ninja world will never be truly peaceful, after all, if too much spiritual energy is consumed, there will always be some crazy people!

Among them, the Uchiha family is the most significant, who made his family's writing wheel eye directly related to the Yin attribute chakra?
