It didn't take long for Yasui to wake up. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoThe three-legged golden crow will not put a heavy hand on his own apprentices.

"How? Yamizu. The three-legged golden crow asked with a nonchalant expression.

"Feeling...... It's scary...... That illusion was too real. Yamizu replied with a confused expression.

"I ask you how your body feels?" The three-legged golden crow asked again.

"Body, ah......" Yashui looked at his body, and then looked at the three-legged golden crow, but did not see any chakra meridians: "The writing wheel eye is closed." ”

"It was just a temporary relief just now, and if you want to solve this problem completely, you should only be able to do it with the sealing technique." The three-legged golden crow was also a little worried: "That's pretty much it for today." Tomorrow you practice at home by yourself and don't come back again. Next time, wait twenty days and come back. ”

"Master, don't you know how to seal?" Yasui asked anxiously, "If the master can completely solve the eye problem, please don't hold back." ”

"My sealing technique doesn't work for you." The three-legged golden crow glanced at Yasui: "It's useless if you're in a hurry." I'll be going to other places in the next few days to help you ask about sealing. ”

"Thank you...... Thank you, master. "Yamizu just blamed the three-legged golden crow. He mistakenly thought that the three-legged golden crow had reservations, so he didn't need the sealing technique to help him.

"Yamizu." The three-legged golden crow called Yasui before Yashui left: "I left an illusion trap in your brain, and as long as your writing wheel eye is opened again, it will be activated." Use illusion to disarm your Sharingan. But only once. ”

"I'll take notice." Yamizu bowed gratefully to the three-legged golden crow and dissolved the spiritism.

Yasui walked back to his house. I took off my sunglasses and looked at these eyes that didn't belong to me in the mirror, and I felt a lot of emotion in my heart.

Always, first complete the task assigned by the three-legged golden crow.

Yasui went to buy two catties of rice wine, and then spent the next few days in the house closing the door and closing the curtains. Death refuses to leave the room.

Everyone in the Ape Fei clan is very concerned about Yasui, for fear that Yasui will suffer from some psychiatric disease.

Yasui faced them every time he casually found a reason to perfunctory past. Yasui is very grateful for their care, but there is no way to make Yasui stronger by caring. Yasui now has to cultivate quietly by himself so that he can become stronger.

Twenty days have passed in a flash, and Yasui has not spoken to anyone except for the three generations of Hokage, Konohamaru, and Sarutobi Asma. Yasui's language function is almost lost.

In this training, Yamizu had already spent a lot more time than the fastest student the three-legged golden crow had ever taught.

Yamizu just sighed, he really wasn't a genius.

Not a genius, but Yasui is working hard enough right now. He didn't think about anything else in his mind for a while, except for completing the goal of the three-legged golden crow.

In constant thinking, Yamizu also discovered the true purpose of this cultivation.

When Yasui thought that this training was to exercise the chakra refining speed, the three-legged golden crow did not deny it. But the purpose of this training is not only to improve the refining speed of chakra.

In the process of training, the speed at which Yasui refines chakra is getting faster and faster. By the tenth day of cultivation, the refining speed kept up with the output speed of the chakra.

It turns out that it is not very difficult to improve the speed of refining chakra. As long as they become proficient and work harder, everyone can quickly increase the refining speed of chakra. Those upper ninjas in Konoha have a much faster chakra refining speed when they activate advanced ninjutsu than Yasui now.

At this time, Yamizu also realized the importance of chakra refining speed in battle. For example, if it takes 100 units of chakra to activate a ninjutsu, and the ninja's chakra refining rate is 50 units per second, then it will take two seconds to refine the chakra and complete the process of sealing by the way.

If the Ninja's chakra refining speed is 40 units per second, it will take 2.5 seconds. It took 0.5 seconds more than the original event, and that 0.5 seconds is a great fighter for the enemy.

If it is for speed, a ninja with a refining speed of 40 units per second will only take two seconds to activate ninjutsu, which will result in only 80 units of chakra being used to activate ninjutsu that requires 100 units. In this way, the power of ninjutsu will decrease, and if you don't do it well, it will fail.

That's how important the speed of chakra refining is. Of course, the refining speed needs to be matched by the output speed, and refining a lot of chakras is not output to ninjutsu, which is no different from not refining.

Only on the premise that the chakra refining speed and output speed are fast enough, the cultivation of practicing the seal speed is meaningful, otherwise when the seal is finished, it will be embarrassing before the chakra is in place.

But the increase in the refining speed alone does not seem to make the rice wine boil. There is often a problem in the process of Yamizu's training, that is, at the beginning of training, Yasui's chakra refining speed and output speed are very fast.

But halfway through training, the amount of chakra in Yamizu's cells began to be unable to keep up. At that time, Yasui refining chakra was like squeezing toothpaste, squeezing chakra out of the body little by little. The chakra refining speed has decreased significantly, and the output speed has slowed down.

This is due to the fact that the cells that have just been refined into a chakra state of fatigue.

Yamizu found that there were two ways to solve this problem. The first is to increase the total amount of chakra contained in the cells and the endurance of the cells, which requires long-term exercise. During this time, Yashui has been squeezing the chakra in his cells, so the amount of chakra has also increased a little, but this degree is far from enough.

The three-legged golden crow said that the fastest student can complete this task in only fifteen days, and it is impossible to increase the amount of chakra significantly in fifteen days. So Yamizu felt that the first method should not be right.

The second method is to quickly shift the focus of refining to some places that have not been refined just now after refining a chakra.

For the second method, it took Yamizu five days to perfect it, and then it took another five days to practice the second method.

When Yasui finished training, he first refined chakra from the left half of his body, and when the chakra refining speed of the left half of his body decreased, Yasui used his right body to refine chakra and let his left body rest.
