Written on the front:

If you don't come to another chapter, I guess some people will think that the author is a fungus. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Recently, my mother has been out of the house for many days...... The author has to take care of the business in the store first, after all, he eats there. (Although a big factor is that the author is lazy~)

Recently, it should be the pirate Hokage alternate codes.,Look at the mood of the day (brain hole).。

Above.

Body:

"You're late." Sasuke said coolly to Naruto who walked over to Yuya Yuya.

"You're early." Naruto looked at Sasuke and felt that he seemed to be different from the day before, but he couldn't tell what was the difference. Before he could think about it, Luo Xiu had already "emerged" from him—like a ghost, but with feet.

"Hmm......" Luo Xiu first carefully looked at the physical condition of the two people and the chakra situation attached to the two of them, Indra and Asura: "You two are really completely different." Whether it's character, or talent. ”

"Huh?" The two of them had a tacit understanding at the same time, then squinted at each other with their eyes, and finally turned their heads with a very tacit "hum".

When their attention returned to him, Luo Xiu began the first day of teaching: "Before we start teaching you things, can you tell us what you think is the difference between ordinary people and ninjas? ”

"Ninjas are powerful!" Naruto-san's simple and rude reply.

"Hmm...... It should be chakra. Sasuke-san, after a little thought, gave the answer.

Hearing this, Luo Xiu smiled lightly: "Naruto is right, and Sasuke is right." However, I want to tell you one thing - the strong are not necessarily ninjas. And ninjas, if they want to become stronger, they don't necessarily have to rely on chakra. ”

"Teacher, are you going to teach us physical arts?" Sasuke asked.

Naruto is not smart enough, but when he heard Sasuke's words, he also reacted, no need for chakra, isn't that a physical technique.

Luo Xiu started to warm up: "Yes, the teacher will teach you physical skills first." But not the kind of physical skills you ninjas. In order to extract chakra as much as possible from the cells of the body, many ninjas start to overload the strength of the cells from a very young age. This boost affects the number of cell divisions, which is your lifespan. ”

Hearing this, both Sasuke and Naruto looked unimpressed. Indeed, these two are still children. Death or something, it's a little too far away for them.

Luo Xiu could only say more specifically: "Don't underestimate the reduction of this part of your life. Naruto, you have a relatively good physique in the 'Body Chakra', thanks to the physique of your mother, the Uzumaki clan. Therefore, Naruto's body technique and chakra amount are dominant. However, if it is consumed in large quantities over a long period of time...... You know the original Hokage, right? ”

The two nodded. The original Hokage was undoubtedly the strongest Hokage ever, and although he had been fighting the streets for many years, his legend still circulated in the village.

"Then do you know how the first Hokage died?" Luo Xiu said very seriously: "The original Hokage, like Naruto, belongs to the thousand-armed clan with a particularly long-lived and excellent 'body chakra'. However, when he was young, because of the perennial war, he experienced countless battles, large and small. Too much chakra is refined and consumed, resulting in an overdraft of the cell life. This made the first Hokage, who was in the prime of life, lose all his body cells, and finally die of old age. (Especially the battle with Ban Ye, it was definitely an overdraft of life.) ）

“…… Grunt" Naruto swallowed. With practical examples, he has a somewhat more concrete understanding of the consequences of excessive chakra consumption.

Then Luo Xiu continued to say to Sasuke: "Sasuke, the writing wheel eye of your Uchiha clan, according to the 'observation' of the teacher, the power contained in it is quite powerful. But your people are not able to bear this powerful body. Therefore, the teacher estimates that once you open the Kaleidoscope Writing Wheel Eye, your eyesight will drop dramatically, and you will eventually lose your sight. ”

Blindness, for a ninja, means enduring the end of his career. Especially the Uchiha, who is particularly dependent on both eyes. Sasuke couldn't help but touch his eyes.

"But you don't have to be too careful. Aren't your three generations of Hokage alive until now? This, of course, has been facilitated by peacetime in recent decades. Ah, besides, although I can't see it, it's actually for me, it's been more than a ...... this year" Luo Xiu suddenly stretched his tone.

"One hundred?!" Naruto and Sasuke spoke in unison, incredibly amazed.

"Ten billion years old." Luo Xiu smiled.

......Of course, the two of them did not believe it. In this regard, Luo Xiu has no meaning to justify. People, when you get older, you can see some things.

"Alright, let's get down to business. What I want to teach you today is a simple but very effective set of physical techniques. The effect of exercising the body is not as good as that of the ninja's physical arts, but it is easier than that, and it has the effect of restoring the body and releasing stress, so even small babies can practice it. So first of all......"

Luo Xiu taught the two of them some simple movements. The refining effect of this set of actions will increase with the user's proficiency. But on the whole, the effect is still very subtle, and it takes years of perseverance to be relatively obvious, mainly to repair and adjust the body. This is perfect for the two of them, who have to undergo a high load of training at the ninja school every day.

What the? You say this is slow? Luo Xiu never planned to let the two of them grow rapidly now. Childhood, it's precious.

After that, Sasuke and Naruto discussed with Luo Xiu in order to facilitate exercise and receive Luo Xiu's guidance, and then moved in together. Of course, an old man from the top of Konoha is indispensable in the middle. Anyway, the final result was that Naruto and Sasuke "cohabited" with a group of girls under the envious and hateful gaze.

But Sakura Haruno and Hinata Hinata vaguely know something, except for looking at the two of them, they don't have any special reactions on weekdays. Hehe, Luo Xiu didn't stupidly do nothing in Naruto's body in the time he spent teaching the two of them.

The days passed.

Three years later, Sasuke and Naruto were both nine years old. In the near future, they will celebrate their tenth birthday. Early this morning, Luo Xiu called the two of them to the place where they had practiced in the past, and first asked them to do the actions that had been repeated and increased for three years.

The two children didn't notice that in the past three years, they had been moved by the Luo Xiu Church more than ten times as much as at the beginning. In the past three years, Luo Xiu has increased his movements a little bit every few days. It could be just a finger movement, or it could just be a little more force on a muscle. Before they know it, their physical fitness has reached a very good level.

"Ah, that's it, so starting today, the teacher will officially teach you the method of [fighting]." Luo Xiu sat down cross-legged: "The method of refining chakra, the teachers in the school have taught it, right?" ”

"Yes." The two nodded.

"Hmm. What the teacher taught you today is a little bit improved on this basis. As he spoke, Luo Xiu made a seal, and then his body changed from a ghost state to a substance: "The chakra you know is to refine the chakra through the spirit, squeezing out the energy called chakra from the cells of the whole body. But you should have found out, right? The speed of refining chakra by himself is a little slower and more difficult than that of other students. ”

“！” The two were shocked: "Could it be ......?"

"It's a pot for the teacher." Luo Xiu looked calm: "Didn't you find that the physical movements you practiced had increased?" ”

"Huh?!" The two of them really didn't notice it.

"Being a teacher will not harm you." Luo Xiu continued: "In the past three years, you have practiced the physical arts, in addition to restoring the body, you can also allow the body to slowly absorb the natural energy of this world. Oh, by the way, you don't know about natural energy yet. Come, come and give you a science popularization for the teacher......"

After this and that, and that and that explanation, Sasuke and Naruto finally knew what had happened to them. In a word, it is [Passive Immortal Mode].

Some people may say that the immortal mode is very risky. The answer is yes. Once the natural energy in the human body exceeds 30%, the phenomenon of petrification occurs. This is what our predecessors have summed up with their lives after cultivating natural energy.

At this point, Luo Xiu has nothing to do. That's why it took him three years to make the bodies of the two people memorize, and remember the absorption ratio of natural energy little by little. And through this set of actions, a [valve] was created in their bodies that restricted their natural energy.

Therefore, when the two of them use the chakra method taught by the teacher in the school to refine the chakra, the natural energy that is not passively used will play a hindering role. It feels very similar to the chakra flow of the Tailed Beast that interferes with the power of the human pillar, but the essence is different.

After the two of them used Professor Luo Xiu's method, they really refined the chakra very smoothly, and then-

"Boom!" Naruto took a step very normally, and the ground was suddenly stepped out of a big pit, and his whole person jumped high ~ and fell down, smashing out a deep pit.

"Boom!" Sasuke was about to laugh at Naruto, but as soon as he leaned back, his waist bent back sharply, and his head smashed into a deep pit in the ground.

Seeing the two disciples sitting cautiously in place, not daring to move easily, Luo Xiu showed a pleasant smile: "Now the chakras in your whole body have begun to transform into immortal chakras. The massive increase in strength is not so simple to control~"
