Naruto Holy Grail System

(After being reminded by a book friend, the Bagua seal in the previous chapter was changed to the Four Symbol seal, but this does not affect reading.)

"How on earth did you get such a big head?"

Tsunade stared at Hatake Izaya strangely, her eyes longing.

She thought about it, and the more she thought about it, the more she felt that what Hatake Rinya said was feasible.

The theory is feasible.

Although the operation will be much more complicated and may even extend the development cycle of this technique.

But with the Four Symbols Seal and other tailed beast sealing techniques at the forefront, this idea is obviously correct.

There's no reason why someone with a huge amount of chakra like a tailed beast can use it, but not a human's own chakra, right?

Hatake Rinya didn't know whether to laugh or cry: "As you can see, it looks like this."

The issues regarding the medical ninja training system mentioned to Tsunade earlier were based on the knowledge from previous lives.

But this time, it was a pure flash of inspiration.

It can even be said that he didn't realize this problem when he watched the anime.

It wasn't until he had a deeper understanding of the structure of the Yin Seal that he realized a problem.

A particularly important question.

As we all know, the so-called chakra amount does not refer to how much chakra is stored in the body.

In fact, the amount of chakra that ninjas often talk about actually refers to the total amount of chakra that a ninja can extract without replenishment or rest.

Simply put, it can even be understood as the limit of physical energy and mental energy.

The quality of these two items directly affects the total amount of chakra.

But the embarrassing thing is that these two qualities are very confusing, and there is no formal way to improve them.

At least for humans, this is a shackle that is difficult to break.

But Tsunade took a different approach.

She wanted to store chakra and release it directly when needed.

By then, the amount of chakra released will be comparable to that of a tailed beast.

Of course, this idea was probably not the first one that came to Tsunade's mind.

However, Tsunade was the first to overcome this problem.

She has successfully developed a way to store chakra, and now she only needs the finishing touches!

At this time, Tsunade suddenly asked: "By the way, do you have any other ideas?"

This time, Tsunade also became interested in Hatake Izaya's thoughts.

Inspiration is so important sometimes. A flash of inspiration may be better than someone else's ten years of hard work.

Hatake Rinya thought for a while and said: "Once the physical and mental energy is exhausted, people will die. Am I right in saying that?"

"Yes."

Tsunade nodded, a little surprised why Hatake Rinya suddenly brought up this issue.

Isn't the issue of developing her technique being discussed now?

But Hatake Rinya was indeed right.

It's okay to run out of chakra, but you must not refine chakra by squeezing your body.

This is something that everyone who embarks on the road of ninja will be told.

Because the method of refining chakra is very dangerous, as long as it is used continuously, it will drain the last trace of energy from the cells.

By then, a large number of cells will die, and the person will die.

Hatake Rinya continued to ask: "If physical and mental energy are replenished, can people live longer?"

"This...isn't possible?" Tsunade said hesitantly.

"Why is it impossible? The reason why people die is actually caused by the aging of cells. If the cells can be replenished with sufficient energy, the body will not age. Doesn't that mean that it will not die?"

Tsunade rolled her eyes and said: "Your idea is good, but the aging of human cells cannot be stopped."

"Okay, then I have no doubt." Hatake Izaya spread his hands and said.

This made Tsunade almost vomit blood.

She wanted to get more ideas from Hatake Izaya!

It ended up being a Q&A?

In fact, Hatake Rinya was also helpless.

He just suddenly thought that the beauty-preserving effect brought by the Yin Seal was actually equivalent to maintaining cell vitality, so that the body would not become old.

So he suddenly thought, if cells remain active, can they achieve the effect of prolonging life?

Besides, he doesn't even understand why cells age, so how can he offer any advice?

Also, in the original work, after Tsunade releases the Yin Seal and uses up her chakra, her body will age rapidly.

From this point of view, the Yin Seal does not really keep the body's cells in peak condition.

Of course, it's too early to say this now.

I'm afraid even Tsunade, the developer of the Yin Seal, didn't realize that this technique also had the effect of rejuvenating one's appearance.

Facing Tsunade's destructive gaze, Hatake Rinya said helplessly:

"What do you think of inspiration? Chinese cabbage?"

"Well." Tsunade also understood that you can't force something like a flash of inspiration, "Then if you have any other ideas in the future, remember to come to me for details."

"No more, it doesn't exist."

Hatake Rinya decisively refused. He felt that Tsunade regarded him as a creative cash machine.

To be honest, he didn't think he was really comparable to those geniuses in the ninja world.

The only thing worthy of praise is nothing more than the knowledge gained in the previous life.

Compared to real geniuses like Senju Tobirama and Orochimaru, he felt that he couldn't even catch up.

At this time, Tsunade asked: "Since you think my move is powerful, do you want to learn it?"

"This... of course I want to learn."

Hatake Rinya hesitated for a moment, but finally affirmed.

Two months ago, when he came into contact with Tsunade, it was probably because he wanted to suppress the secret seal.

But now he found that it was enough to directly use the system to improve, so his heart fell silent again.

However, after reading Tsunade's notes, he suddenly discovered that the Yin Seal was very similar to "cultivation"!

So, he became eager to try again.

Always relying on the system to become stronger makes him feel like he is controlled by the system.

Now, another bright road is in front of us, there is no reason not to try it!

Besides, this is "cultivating immortals", and someone like him, Hatake, also has a dream of becoming an immortal.

"If you want to learn this ninjutsu, you have to start with Kaiju." Tsunade said.

Hatake Rinya suddenly showed a bitter face.

What Kaili focuses on is the explosive power and control of chakra, and these two points happen to be his shortcomings.

Just when Hatake Rinya wanted to ask if there was any shortcut, there was a knock on the door.

dong dong.

"Who?" Tsunade called.

"Tsunade-sensei, it's me." Uchiha Mikoto's voice came.

"What's the matter?" Tsunade asked.

"Ah, it's not a big deal. I just want to ask, do you want to continue practicing today?"

Hearing this, Tsunade was slightly taken aback.

She looked at the sky and found that the sun was shining brightly.

It turned out that before I knew it, an hour had passed.

"Just a moment, I'll change my clothes and come back." Tsunade replied.

She was still in her pajamas.

Looking at Hatake Izaya who was drinking tea to soothe his throat, Tsunade said: "Take this note back and continue studying it."

After saying that, Tsunade walked towards the room.

It wasn't until she entered the room and just before closing the door that she said suspiciously: "Don't peek, or I'll beat you to death!"

Hatake Rinya, who had just taken a sip of tea, suddenly gushed out.

He wondered whether he should laugh or cry: "Who do you think I am?"

He suspected that it was Jiraiya's fault.

Tsunade must have been frightened by Jiraiya, so she was suspicious.

But someone like him, Hatake, is a gentleman!

How could it be possible to go back and peep?

"Trigger D-level mission: See the face of truth in the hole"

"Mission content: Spying on Tsunade..."

"Task Reward: Crystal Stone"

"..."

This system must be toxic!

……

When Hatake Izaya and Tsunade walked out together, Uchiha Mikoto was stunned.

And change clothes and stuff.

"Senior, you are..."

"I encountered some problems in my practice, so I came to Teacher Tsunade early to solve my problems." Hatake Rinya explained.

Ninjutsu, especially advanced ninjutsu, is very confidential.

Hatake Rin didn't get Tsunade's permission, so naturally he wouldn't reveal the Yin Seal.

He still has this sense of confidentiality.

"Is that so? That senior has really worked very hard, so I have to work harder." Uchiha Mikoto smiled.

"Where's Ukyo?" Tsunade asked.

"Ukyo-san doesn't seem to be in the room, and I don't know where he went." Uchiha Mikoto said worriedly.

"He must have escaped. This guy wanted to have fun since he came to the capital." Hatake Rinya couldn't laugh or cry.

Although their time together was short, Hatake Izaya felt that he had seen through Ukyo.

That guy does everything based on his interest, and he can do whatever he wants.

Fortunately, his nature is not bad, and he has never thought of doing anything bad.

"This boy is too lazy."

Tsunade was also very angry.

Now that she has become the guidance jounin of Team [-], Tsunade has no intention of just muddle along. Even for Uchiha Mikoto, she takes the responsibility to guide without any ambiguity.

But since we are human beings, it is inevitable to bring personal feelings into things when we do things.

Therefore, Tsunade prefers Ukyo, who is cuter than a girl, to Uchiha Mikoto.

Therefore, what he taught Ukyo was his best medical ninjutsu.

But Ukyo actually ran away?

"How about we go find him?" Hatake Rinya said helplessly.

He was actually worried that Ukyo would cause trouble everywhere and eventually get into trouble.

Especially at this juncture when the "temporary Konoha mission" was under suspicion.

Tsunade snorted and said: "No, you go to practice first, and I will go and find him myself."

Hatake Rinya couldn't help but smile: Ukyo would probably have a hard time if he was caught by Tsunade.

But since Tsunade spoke, Hatake Izaya and Uchiha Mikoto naturally had no objection.

After Tsunade left, the two of them walked together and headed outside the city.

Not long after, we arrived at the place where we practiced yesterday.

Without any nonsense, the two started practicing immediately.

Hatake Rinya took out his notes, skipped the content that was not needed for the time being, and directly found the part about strange power.

The so-called strange power is actually concentrating chakra on one part of the body, causing an explosion of earth-shattering effects.

Among them, chakra control plays a vital role.

Therefore, learning strange power must start with the mechanics of chakra control.

According to the records in the notes, so-called control is actually inseparable from a person's spirit.

To understand it simply, it can be summarized in four words.

focus!

Carefully feel the flow of refined chakra and then control it.

Yes, it's that simple.

However, it is far from simple to operate.

Yes, when a ninja meditates, it is indeed easy to concentrate. After training, it is possible to have no distracting thoughts in a short time.

However, what must be understood is that when fighting, there is not so much time to hold your breath and concentrate.

Fortunately, Tsunade's notes have a very detailed explanation for this, and she uses four words to describe it.

Practice makes perfect!

"I see, the so-called careful control is just the basis. When you actually use it, you rely on the instinct that has been tempered over time!"

Hatake Rinya looked at the description of the strange power in his notes and suddenly realized.

That is true.

Even for people with outstanding talents, it is actually difficult to concentrate fully and not have distracting thoughts during battle.

Moreover, concentrating on controlling chakra means that it is difficult to notice other problems, and there may be loopholes that the enemy can take advantage of.

This is obviously a waste of money.

"But in the final analysis, the requirements for control are still very high. Everything is difficult at the beginning. Even if you want to achieve practice makes perfect, the first condition is to concentrate the chakra first. If you can't even concentrate, then there will be no explosion. Once you talk about it, let alone form an instinct..."

Hatake Izaya smiled bitterly, this was his shortcoming.

However, things have to be tried.

It's not his style to give up without trying.

"Concentrate, it's easy to say..."

Hatake Rinya closed his eyes and held his breath in concentration.

The sound of water, wind, insects and birds flowed in my ears.

Hatake Rinya also began to regulate his breathing and thoughts, and control distracting thoughts.

Finally, Hatake Rinya was attracted by Uchiha Mikoto's breathing sound.

This is it!

Did you say that once you close your eyes, your mind will be clear of distracting thoughts? !

Isn't this a necessary skill for time travellers? !

There was no way, so Hatake Rinya had no choice but to refine some chakra and try to control it first.

"what?"

A surprised voice sounded, and the chakra he had just controlled dissipated immediately.

Hatake Izaya opened his eyes with a strange expression.

"Chakra, is it so easy to control?"

He found that he could control a ray of chakra easily.

And this is something that could not be done in any case before.

Now I suddenly did it, no matter how you look at it, it's not normal.

Hatake Rinya, who did not believe in evil, concentrated again, controlled the chakra in his body, and slowly concentrated it on his fingertips.

When he opened his eyes, he saw a blue color spurting out from his fingertips.

Very thin, very thin, but there it is.

Hatake Rinya was stunned immediately.

You know, under normal circumstances, chakra that is not controlled will be dispersed to various parts of the body and dissipated.

If the amount is too large and not controlled, the whole person will be wrapped in chakra.

Very domineering, but also wasteful.

But the phenomenon of dissipating from the fingertips like this is proof that chakra is directed to one place.

Hatake Rinya touched his head, his hair was still there.

"I'm not bald either, so why have I become stronger?"
