The last boss of the ninja world

"Are you ready?"

"I'm ready, sister!"

"Then let's get started?"

"Well, sister, please start."

After the morning meeting, in the Musashi lounge.

Tsunade moved a blackboard from somewhere, and Musashi found a small stool. Like a good baby, he sat on the stool obediently, holding his head high and expecting Tsunade to start explaining.

Although he had already greeted Uchiha Yaxuan in advance, no one was allowed to approach Musashi's lounge.

But before the lecture began, Tsunade still made a mark and used a "quiet technique" to completely eliminate the possibility of being overheard.

Seeing Tsunade being so solemn, Musashi couldn't help but feel a little nervous.

He had a hunch that what Tsunade was going to teach him next was very remarkable, otherwise Tsunade wouldn't be so cautious.

"Do you know what chakra is?"

The class officially started. Tsunade changed her easy-going attitude when the two got along, and asked Musashi seriously with a straight face.

Musashi was a little confused and didn't understand why Tsunade asked him such a simple question.

After thinking for a while, he replied: "Chakra is the source of energy that activates Ninjutsu, which is also the "energy" of Ninjutsu. It has seven changes in nature: wind, water, earth, thunder, fire, yin, and yang. It is the ninja's The energy of the mind and body, as well as the so-called "energy", are mutually converting the energy and chakra in the body, and the efficiency of the conversion will also affect the ability of the caster."

Musashi's answer was quite satisfactory. It was based on Kishimoto's settings compiled by a certain degree, and it was also the content of knowledge currently taught in ninja schools.

Tsunade nodded. Musashi's homework was very solid in terms of basic knowledge and theory.

Tsunade then began to talk about the key points of knowledge that were not taught in school.

Turn around and write the four words "spirit", "energy", "body" and "energy" on the blackboard.

He cleared his throat and said: "Actually, [energy] is not only stored in the 300 trillion cells of the body, but there are also various kinds of [energy] in the world."

Musashi quickly picked up a pen and wrote down the key points of this knowledge in a small notebook.

Tsunade added: "The chakra and [energy] that ninjas usually refine come from the cells in our bodies, but you have to remember that other [energy] can also be used by ninjas with the right method."

Hearing this, words such as [Power of Nature] and [Senjutsu Chakra] came to Musashi's mind.

However, Musashi did not ask any questions and continued to sit and wait for Tsunade to explain.

"There are very few ninjas who can use other [energy]. Looking at the entire ninja world, there are not many. Among the ninjas I know, only my grandfather Senju Hashirama and Jiraiya can master this terrifying power. .”

Musashi finally confirmed that Tsunade was talking about [Senjutsu Chakra].

But Tsunade herself doesn't know the magic of immortality, so why should she teach Musashi the magic of immortality?

So Musashi still didn't ask questions at will, and just listened to Tsunade's continued lecture: "Not every ninja has the opportunity to master other [energy] methods, but a qualified medical ninja with huge chakra is an indispensable prerequisite. condition."

"Only with huge chakra can we provide continuous support to injured ninjas when needed."

"So, my grandfather, the First Hokage, developed a secret technique that can store chakra based on the method he mastered."

The secret to storing chakra?

Musashi's heart suddenly beat violently. In the entire Hokage, there were only three people who mastered this secret technique. They were the First Hokage Senju Hashirama, Konoha Sannin Tsunade, and Konoha New Sannin Haruno Sakura.

And the name of this secret technique is the famous [Yin Seal]!

No, no, no, no...

The ninjutsu that Sister Tsunade wants to teach me is the legendary [Yin Seal], right?

"Look here!" Seeing that Musashi was distracted, Tsunade patted the blackboard angrily, and then said: "The essence of Chakra is the product of the combination of the [energy] of the ninja and the [energy] in the body."

Musashi quickly straightened his posture and stared at the blackboard intently.

While taking a pen to record, he nodded in response to Tsunade, indicating that he was listening carefully.

Tsunade glanced at Musashi's notes with satisfaction and placed her finger on the two characters "Spirit" and "Energy".

"We can only obtain physical [energy] through food, but [spiritual] power is the power that each of us has. Depending on whether we exercise or not, everyone's [energy] will be different."

“But you have to remember that [Spirit] is not equal to [Energy]. [Spirit] is the power given to us by our souls, which can be restored through sleep, while [Energy] is our strong willpower through training. [Spirit] 】The power transformed.”

"The secret technique I am about to teach you really stores [energy]!"

Musashi took notes, and after hearing this, he finally couldn't help but asked Tsunade: "Sister, what exactly is [energy]?"

"[Energy] is Chakra. To be precise, [Energy] is the most important component of Chakra."

Tsunade was very satisfied with Musashi's question. She pointed to the blackboard, picked up the chalk and connected [energy] and [energy].

Then he continued: "[Energy] can be understood as our willpower, but it is different from willpower. It has no entity and is an invisible force. But it really exists."

"For example, the secret art practiced by Jiraiya, the chakra he calls [Senjutsu Chakra], uses [energy] that is not the [energy] produced by the body, but the energy that already exists between heaven and earth. Plant [natural energy].”

"The [natural energy] between heaven and earth, if there is no correct cultivation method, even if ordinary ninjas can sense its existence, it will be difficult to utilize it."

"Because if you really want to master [natural energy], in addition to being able to absorb it, you also need to use your own [energy] to turn it into your own power."

"Otherwise, not only will it not be able to be used by ninjas, but it will be absorbed randomly and produce some backlash effects. For example, the [natural energy] absorbed by Jiraiya, there is a high probability that people who do not understand the cultivation method will turn into stone. frog."

Musashi roughly understood what [energy] was, and nodded heavily.

[Energy] After all, it really exists and is invisible.

It can transform [energy] that cannot be used by itself into [energy] that can be used by itself.

Seeing Musashi's sudden enlightenment, Tsunade wiped away the words on the blackboard with satisfaction, and then drew an extremely complex technique on the blackboard.

When the technique was formed, Tsunade did not need to explain the functions of the runes in the technique one by one. [Real-time Translation] helped Musashi analyze the technique into words he could understand.

The general meaning is: [continuously absorbing and storing certain two types of energy].

[Seal] To be precise, it stores two kinds of energy. It is like a bagua, storing the body's excess [energy] and [physical] energy inside.

When the seal is released, a large amount of physical [energy] and [energy] will flow out crazily.

They can be combined together to form a huge chakra in a short period of time!
