The last boss of the ninja world

"Did you feel it?"

"It's still a little bit... I seem to 'see' something, but it also seems like I don't 'see' anything."

After a long time, Musashi replied ashamedly.

His talent is really not very strong. Without Tsunade's personal guidance, he may not be able to master the method of chakra materialization in this life.

"very good……"

Musashi's answer made Tsunade very satisfied.

Because that kind of power can only be understood but cannot be expressed in words. Musashi's performance now is much better than when her grandfather taught her.

In the inner vision,

Musashi is like a little fish swimming in the sea. He can clearly sense that there is something under the deep sea, but no matter how hard he swims, he still cannot dive to the bottom of the sea.

It was like mosquitoes buzzing around his ears in summer. He had clearly heard the sound of mosquitoes flapping their wings, and reached out to catch them, but couldn't catch anything.

"Don't be impatient!"

Tsunade's voice came again.

Musashi closed his eyes and nodded. There was no point in being impatient. The more impatient he was, the farther away the ethereal feeling was from him.

"Sister, I seem to 'see' it..."

At some point, Musashi suddenly shouted excitedly to Tsunade.

The fish swimming in the deep sea finally discovered what that mysterious power is!

As Musashi dived deeper and deeper, the pressure around his body began to increase. The force he could feel but couldn't grasp was actually the sea water itself.

In other words.

The power that restrains the chakra group is actually chakra itself!

"Okay, you can open your eyes now."

Tsunade withdrew her chakra, Musashi slowly opened his eyes and saw that Tsunade's forehead was covered with sweat.

Nearly five hours have passed since Musashi began to sense it. If it were a ninja whose chakra was not deep enough, he would have collapsed and died long ago.

Musashi pinched his sleeves distressedly, gently wiped away Tsunade's sweat, and complained: "Sister, don't force yourself next time! If you can't feel it once, I can try a few more times. Excessive consumption of chakra is very dangerous. "

"It's okay, this is just a little chakra consumption." Tsunade panted heavily and said bravely: "If you can't sense that kind of power the first time, it will be difficult for you to sense the existence of that kind of power later."

"..." Musashi didn't know what to say.

I thought to myself that Uzumaki Naruto had failed countless times when learning the Rasengan. How could he not feel it the first time and then find it difficult to feel it later?

But Musashi forgot.

The materialization of the Rasengan was caused by Namikaze Minato using high-speed rotation to drive the chakra to be highly compressed based on the characteristics of the tailed beast jade, and finally obtained the materialized chakra energy group.

The embodied chakra that Tsunade taught Musashi to master at this moment is fundamentally different from the Rasengan in principle.

It does not rely on the power of the spiral to compress chakra, but relies on the refined control of chakra to make chakra highly compressed.

The chakra mass can be regarded as a mass of water. The caster needs to control the movement trajectory of each water molecule and let them swim continuously towards the center of the chakra mass, thus restraining themselves and other molecules from escaping outward.

"Sister, how can I master this power?"

After Tsunade regained some strength, Musashi asked again.

"Human energy is limited. You must cultivate that power into a natural reaction instead of using your mind to control that power." Tsunade spread her palms and prepared to demonstrate to Musashi again.

But Musashi put his hand on Tsunade's palm, shook his head, and signaled to Tsunade sister that there was no need to continue the demonstration.

Musashi's distressed expression was written on his face, and Tsunade felt very relieved and felt warm in her heart.

It's just that she is a little stupid and can't tell the difference.

I can't tell whether that kind of warmth comes from the relationship between men and women?Or does it come from the relationship between a disciple and a master who feels sorry for his master?

"Human energy is limited..." Musashi listened to Tsunade's words and gradually gained some understanding.

The human brain is smarter than humans think!

Tsunade's so-called cultivation of natural reactions is actually similar to the [Simplified Seal] theory proposed in the [Advanced Water Release Theory] left by the Second-Daime Hokage.

Through long practice, the flow of chakra is cultivated into a conditioned reflex, rather than deliberately guiding the chakra in the body.

The general principle is the same, which is not very satisfying for Musashi.

Now he opened his palms and gathered a dark green [Yang] attribute chakra light group, then began to guide the chakra to compress inward, and continued to inject more chakra into his hands.

Unfortunately, in less than a second, the extra chakra leaked out and turned into a stream of dark green smoke, which finally melted into the air.

"When practicing, you can use pure chakra balls to practice, eliminating the step of changing properties."

"Well, thank you sister."

It’s great to have a master...

Musashi got the advice, and when he concentrated chakra for the second time, a blue ball of light appeared in his hand.

The color of the chakra mass without changing properties is blue.

Without the change in nature, Musashi found that it was much easier to control his chakra regiment.

The second time Musashi compressed the chakra mass, it lasted for [-] seconds, which was [-] seconds longer than the first time.

"Don't focus too much on controlling chakra compression, but remember the feeling of chakra being compressed in your hands, and then continue practicing according to that feeling."

Tsunade reminded her at the right time, and was very surprised at Musashi's performance.

At the beginning, it took her a full year to keep the chakra mass compressed for two seconds. Musashi actually released it for the second time and maintained the chakra mass for [-] seconds.

Genius, he really is a genius!

Of course, Tsunade conditionally ignored her age when she first learned. At that time, she was less than five years old. If she could overcome her playfulness and practice ninjutsu, she was already a level better than 90.00% of geniuses.

"If you cannot develop a natural reaction in a short period of time, you can try to release only a small amount of chakra at a time and let them condense into a ball the size of a rice grain in your hand."

"Sister, are you referring to refined chakra control?"

Musashi listened, and suddenly his eyes lit up.

"Well, you can understand it that way. But fine control of chakra is just a concept. Whether it is such a small ball of chakra or such a large ball of chakra, there is essentially no difference between them."

Tsunade nodded, then spread her hands, and a chakra ball the size of a glass marble appeared on her left hand, and a chakra ball the size of a basketball appeared on her right hand.

Then, like magic, Tsunade made the two chakra balls rotate back and forth between her hands. The big ball and the small ball could react differently as they wished.

Is refined chakra control just a concept?

Musashi thought and suddenly understood what Tsunade meant.

"Sister, are you saying that fine control has nothing to do with the amount of chakra released. What matters is only the ability to control chakra?"

"Well, smart little guy! So when you practice, you don't have to release a lot of chakra and tire yourself out."
