A week later.

"Huh?" Izumi Shinyu stopped what he was doing.

Spread out the palm of your right hand and look at the prismatic imprint on it.

"Here we go again......" Izumi Xinyu's face was a little ugly.

The wedge has already begun to thaw.

Maybe it's because his soul is stronger, maybe it's because he's a ripple messenger, or maybe it's because of something else.

He could clearly sense that his body was being invaded by an alternative energy.

In fact, strictly speaking, the word "invasion" is not entirely correct.

It was only after he knew the final result of this energy that he chose to use the word "invasion" with obvious malice.

Because after the invasion of this energy, his physical fitness is strong at a speed that is visible to the naked eye.

To put it intuitively, even if he doesn't do anything for a day, he just lies there.

The speed at which his physical fitness has increased is already comparable to a week's workout.

This is still his conservative estimate, you must know that the state of the body is different every day, and the effect of exercise is different.

If you really let him practice strictly for a week, it will not be as fast as the current speed.

The physical fitness is strong, and the amount of chakra also increases.

According to his projections, if this rate increase remained constant, his chakra would increase by about a tenth in a month's time.

Don't look at it as just a tenth.

You must know that his current amount of chakra is one-tenth of the same as all the chakra of an ordinary ninja with no bloodstain limit.

"Izumi, what's wrong?"

Just as he was lost in thought, Naruto came over carrying a book.

After a week of evil replenishment, his current knowledge reserve has reached the requirements of cultivating the Flying Thunder God Technique.

Now the book in his hand has changed from the original learning materials to the second and fourth generations of Hokage's experience in practicing the art of flying thunder gods.

"It's nothing, it's just thinking about the next cultivation method of the Spiritualization Technique." Izumi Xinyou shook his head slightly.

Compared with the cultivation of Naruto and his predecessors, he who chose to cultivate the art of spiritual transformation was much more difficult.

Unlike the direct threshold of the Flying Thunder God, the Spiritualization Technique involves more mysterious things about the gods.

Even in Konoha, there are not many examples of successful cultivation.

And most of the successful cultivation has only cultivated a scale and half a claw.

I haven't figured it out, and it's even more impossible to leave a spiritual experience.

Tsunade's last boyfriend, Kato Tsunade, is a successful example.

But helplessly, people have a short life, and the experience books left behind have not been systematically sorted out.

It's just his original cultivation ideas and feelings.

This kind of essay, even Kato himself, believes that it takes a period of time to think about it before he can remember what he wrote.

Needless to say, it's even more difficult for Izumi Shinyu to understand.

Even certain writing habits, such as some sentences with special meanings, he had to go to Tsunade.

Ask Tsunade to explain to him the meaning of these sentences.

"Haha, take your time." Naruto patted him on the shoulder.

"What about you? How's it going? Izumi Xinyou nodded slightly and asked.

"I've found some ideas."

Naruto glanced back, and it could almost be said that it was a shadow clone all over the mountains, and he also nodded slightly.

Izumi Shinyu: "(≖_≖)! ”

Not far away, in the shade of a tree, a pen that is also placed in his hand.

He naturally heard the conversation between the two, looked up at the blue sky, and couldn't help but secretly say in his heart:

Old man, your fire seems to have made the new buds of Konoha grow......

"Alright, that's all for today." Jiraiya stood up.

"Isn't it early?" Naruto looked at the sky and asked suspiciously.

"People don't beat iron, they always need some time to rest, don't they?"

He also patted the weeds off his buttocks.

"Besides, your cultivation speed is already very fast, and it's not good to be in a hurry."

"You know, Kakashi and Asmana haven't touched the shadow yet."

For this, both he and Tsunade are quite helpless.

As the two of them who were the objects of their key training, their cultivation speed was surpassed, and the two boys they placed in the second echelon were surpassed......

It can only be said that the world is impermanent.

"Great! The art of shadow clone, solution! ”

In an instant, smoke filled the small plain.

I have no choice but to support my forehead.

Well, he retracted what he just said, it's not Kakashi, they can't do it, they can only say that Naruto has opened a hook here.

"Xiao Quanzi, how is your spiritual cultivation going?" Jiraiya asked.

"I can already feel the soul." Izumi nodded.

In fact, he was quite surprised by this.

It was also after cultivating the art of spiritualization that he discovered that the technique of spiritualization was simply tailor-made for the stand-in messenger.

He dared to say that any stand-in envoy in the previous life could cultivate the art of spiritualization, as long as he was not a fool, he could cultivate it.

Because the feeling of the soul out of body of the spiritual art and the feeling of the specific stand-in cannot be said to be very similar, it can only be said to be exactly the same.

If there is any difference, it is that the spiritualization technique controls it, and it is really your own soul.

If the stand-in is injured, the body will also be injured, but that is only reflected at the physical level.

The soul hurts, tsk tsk......

However, there are still difficulties, and most of the stand-ins of the stand-in messengers are embodied through the stimulation of "arrows".

It's like a game, you directly use the plug-in to brush through the level, kill the boss and get the final reward.

And the art of spiritualization is to let you play the level by yourself, little by little.

Anyone who has played the game knows that sometimes the boss is not difficult to fight, but the difficult thing is how to get in front of the boss.

At present, the process that Quan Xinyou is going through is to hit the "little monster" by hand, grinding the progress bar little by little.

Finally, he spiritualized and embodied his soul.

"Let's go, Tsunade, they should be waiting for us." Zilai also bowed slightly.

For some reason, he also has a certain understanding of the art of spiritualization.

Therefore, I also know that the most difficult step in the art of spiritualization is actually to perceive one's own soul.

The latter process, to put it simply, is water grinding kung fu.

The two followed Jiraiya all the way into an estabaka.

"Hey! It's late! ”

As soon as the three of them entered the house, Tsunade's complaints came to their ears.

"Our cultivation ground is not in the village." Jiraiya said, to be in front of Tsunade.

At the dinner table, in addition to Tsunade, there were Kakashi and Asma, who hadn't been seen for a week.

Izumi Shinyu and Naruto consciously found a place to sit down.

"Eat by yourself and talk by yourself." Tsunade said inexplicably.

"Don't look at me, this dinner is for you." Jiraiya shrugged.

Izumi Shinyu and Naruto withdrew their gazes and looked at the two opposites suspiciously.

What puzzled them was that they saw a little cramped in the two old fritters, Kakashi and Asma.

"That, that......"

Kakashi scratched his mask with his fingernails.
