I am the strongest Hokage of all time

In the courtyard of the huge Sarutobi family patriarch's mansion.

Hiruzen was playing hide-and-seek with Dango.

Tuanzi covered his eyes with his hands and muttered: "28, 29, thirty, okay Brother Hiruzen, I'm here to find you."

Tuanzi took his hand away and opened his eyes wide.

Looking at the surrounding yard, he seemed a little at a loss.

During the time she was playing hide-and-seek with Hiruzen, she didn't find Hiruzen even once.

On the contrary, Hiruzen found Dango every time.

After all, Hiruzen still has an adult soul.

If you can't win playing peek-a-boo with a three-year-old, it's a failure.

In fact, Hiruzen disliked playing with children at first.

But as he played, he seemed to have returned to his childhood in his previous life, and he was having a great time.

The group walked around the yard again and again.

No sign of Hiruzen was ever found.

At this time, the two patriarchs in the room walked out of the door.

Shimura Heiichi smiled and gestured to Danzi: "Duanzi, go home with dad."

After Tuanzi heard this, he said with some unfinished thoughts: "I'm going home."

But she still returned to her father obediently.

Sarutobi Sasuke turned towards the roof and said, "Come down, Hiruzen."

So Hiruzen stuck his head out from the roof and slowly climbed down from the pillar on the side.

"Like a monkey." Sasuke muttered.

Tuanzi laughed out loud when he heard this.

Even Heiichi couldn't help laughing.

Hiruzen was speechless, why did Hiruzen have to bear this nickname after traveling through time and becoming Sarutobi?

After sending Heiichi, Dango and other visiting Shimura family members out of Sarutobi's station.

Sasuke and Hiruzen, father and son, returned to the room.

"Hiruzen, you are three years old," Sasuke said.

"Yes, father." Hiruzen didn't quite understand what Sasuke meant by saying that.

Sasuke looked at his son who had been much more mature than his peers since he was a child.

Sasuke always feels that his son is too mature, but from playing with the little girl from the Shimura family today, it can be seen that he is still a little childish.

"At three years old, I can teach you how to refine chakra." Sasuke continued.

"Chakra." Hiruzen almost forgot about this.

The basis of the power system in Naruto's world is chakra.

Whether it is ninjutsu, taijutsu, or genjutsu, chakra is actually needed.

Chakra is the product of an equal mixture of self-spiritual energy and physical energy.

It is a kind of energy extracted from 130 trillion cells in the body.

It can be said that chakra is the powerful foundation of a ninja.

Those ninjas who stand at the top of the ninja world all have extremely large amounts of chakra.

Some are even comparable to tailed beasts.

As for Senju Hashirama, he has more chakra than the tailed beasts, and he is a monster-level existence.

A kid from a big family like Hiruzen.

Basically, I came into contact with chakra training when I was three or four years old.

He already possesses basic combat abilities at the age of five or six.

If the war situation is urgent, children of this age will be sent to the battlefield at this time.

This was the brutal Warring States Period.

Hiruzen followed the method taught by Sasuke and let his spirit sneak into his heart.

Feel your own mental and physical energy.

As a novice who had just come into contact with cultivation, it took Hiruzen a long time to feel the spiritual energy existing in his brain.

But what shocked Hiruzen was that there was more than just one spiritual energy in his head.

Hiruzen felt three streams of spiritual energy in his head.

A particularly small energy should be the spiritual energy generated by Hiruzen in this life.

The other is a relatively large amount of mature spiritual energy, which should have been brought by Hiruzen in his previous life.

However, Hiruzen also discovered another spiritual energy that was different from these two spiritual energies.

This energy is extremely pure and huge, like the sun in Hiruzen's spiritual world.

Therefore, when Hiruzen successfully entered the spiritual world, he immediately felt this spiritual energy.

The other two spiritual energies belonging to him were only discovered later.

Hiruzen didn't know the origin of this mysterious spiritual energy.

But he estimated in his heart that this energy might be related to the reason why he traveled through time and came to the world of Naruto.

Although he didn't know why he came to the world of Naruto.

Hiruzen tried to use this spiritual energy to refine chakra.

Extract a trace of this spiritual power and combine it with the energy in the body in proportion.

This doesn't sound difficult.

But actually, for a beginner Hiruzen.

It is very difficult to control, extract and manipulate this mysterious spiritual energy.

Hiruzen felt that it took him a long time to transport a trace of spiritual energy into his body.

Combining mental energy with physical energy was another difficult task for Hiruzen.

Keeping mental energy and physical energy in the right ratio is a very delicate job.

Once the proportions are wrong, chakra cannot be formed.

So Hiruzen tried this again for a long time.

Try it over and over again.

Finally, after an unknown amount of time, Hiruzen refined his first chakra.

Hiruzen was very pleasantly surprised, but also a little surprised.

Because he knew how difficult it was to refine chakra for the first time.

It takes an average person about a month to refine chakra for the first time.

Even for a genius, it takes days.

However, it only took Hiruzen such a short time to succeed.

Even if the Third Hokage in the original work was a genius among geniuses, he would not have been able to refine chakra so quickly.

Hiruzen speculated that this must have something to do with the mysterious spiritual energy.

Hiruzen opened his eyes.

Just feeling dizzy for a while.

I felt mentally exhausted, as if I hadn't slept for three days and three nights.

He saw that his father Sasuke Sarutobi was still in front of him.

So he said: "Father, you haven't left yet."

Sasuke said with a strange look on his face: "Didn't you just sit down?"

Hiruzen immediately sensed something was wrong.

I clearly felt like I was immersed in the spiritual world for a long time.

And the mental exhaustion really shows that.

But according to Sasuke's wishes, he had only sat down not long ago.

That means he refined chakra not long after he sat down.

Hiruzen originally thought that he must have missed dinner time because he was focusing on training.

It must have gotten dark outside.

However, Hiruzen looked out the window and saw the sun still hanging in the sky.

This confirmed Sasuke's statement.

Even if Sasuke said that he had just sat down, it was an exaggeration, but the time would never exceed 10 minutes.

Refining chakra in three days is genius.

So what is the point of refining chakra in 10 minutes?

A monster?

Hiruzen was shocked.

At the same time, I think of my own mental fatigue and the mysterious spiritual energy in my body.

Could it be that that spiritual energy can affect the flow of time?

Hiruzen had a preliminary judgment in his mind.

If this assumption is true.

Then there is no doubt that this spiritual energy is Hiruzen's plug-in.

You know, a person's spiritual energy is limited.

And except for families like the Yamanaka clan that master spiritual mysteries, there is no way to train one's spirit in the ninja world.

Therefore, the upper limit of a ninja's chakra is often determined by the upper limit of his spiritual energy.

And Hiruzen himself has an extremely huge spiritual power, which means that his chakra amount will be greatly increased.

More importantly, this mental energy can affect the flow of time.

This allowed Hiruzen to have more time to practice than others.

There is no doubt that this will be the plug-in that will allow Hiruzen to rule the ninja world in the future.
