Naruto started cultivating immortality from creating the Six-fold Immortal Thief

After absorbing it, Yusuke also had a better understanding of the Sage Mode. He could also succeed in the Ryuchi Cave, but at the same time, he also understood that his Sage Mode was not mature enough compared to the Three Holy Lands and Senju Hashirama. He was probably only successful in the environment of the Ryuchi Cave. It would be difficult to succeed in the environment of the Ninja World.

And now he is just like Naruto who just completed the Sage Mode. After turning on the Sage Mode, he cannot absorb the natural energy from the outside world, resulting in the Sage Mode being exited when the Sage Chakra in his body is used up.

Naruto is unable to absorb natural energy in the Sage Mode because of the influence of the Nine-Tails Chakra, but Yusuke has no other way. He cannot absorb the natural energy in the air when he exits the meditation state.

Now he absorbs natural energy by meditating and using his strong mental power to forcibly absorb natural energy. He cannot do it as naturally as the Sages of the Three Holy Lands, just like breathing.

There was a ready-made successful case nearby, so Xiongjie naturally would not let it go, and asked directly:"White Snake, after you successfully practiced the immortal technique, how did you continue to absorb the natural energy in the air!"

White Snake lowered his head, pondered for a moment, and said:"It's breathing! Through regular breathing, you can absorb the natural energy that suits you into your body, and then convert it into natural energy.……"

The white snake told Yusuke all the secrets of the immortal arts that Ryuchidong had passed on to these snakes without reservation.

Hearing this, Yusuke froze on the stone bed:"Breathing~ Exhaling! I remembered the theory of the three dantians, but why did I forget the way to breathe?! As the first step of many cultivation theories, the status of breathing in cultivation is not much worse than the theory of the three dantians."

Yusuke now regretted it very much. If he had tried to absorb natural energy through breathing as soon as he could sense natural energy, he might have been able to normalize the immortal mode and let his body evolve towards the immortal body.

But it's not too late now. He is only twelve years old this year, and he has plenty of time to create his own breathing method.

But the first step to be done now is to transform the chakra in the body into immortal chakra and store it all in the seal of the sea of qi.

He did it right away.

For the next period of time, Yusuke's daily work was to meditate and transform the chakra in his body.

When his mental energy was almost exhausted, he would sleep in the cave of the white snake.

It was not until half a month later that the shadow clone in the ninja world was released and brought a message that Yusuke stopped the transformation of the chakra in his body.

Opening his eyes, Yusuke felt the chakra in the Qi Sea seal, feeling somewhat helpless:"I've been busy for half a month, but I've only converted half of the chakra. I don't know when I can complete the remaining half next time?!"

Looking at the dozen or so shadow clones next to him who were perfecting their breathing and sage mode, Yusuke formed seals with his hands, used the summoning technique to return to the ninja world, and walked towards the gate of the village.

As for those shadow clones, they stayed in the Ryuchi Cave.

Soon, Yusuke arrived at the village entrance. Keizaburo, Kakashi, and the passerby were already waiting here. They were finally going out of the village to perform a mission. Other classes that graduated in the same year had already performed several C-level missions, but their class had been performing D-level missions for the three students' own reasons.

Today was their first time to perform a mission outside the village. The mission was to go to the border of the Fire and Wind countries and eliminate the bandits hovering there.

After getting this information, except for the passerby, the remaining three people knew in their hearts that this group of bandits was most likely the Sand Ninjas from the Sand Village in disguise, so they sent their team there.

It is well known in the ninja world that the Wind Country has the largest land area, but the least resources, especially water and food, which are the two essential resources for survival. Therefore, the Sand Ninja often acts as bandits in the mountains near the border of the Fire Country, robbing the food and water resources of the nearby villages.

Seeing Yusuke coming, Keizaburo said seriously:"Now that everyone is here, let's set off quickly! The details of the mission will be discussed on the way!"

The three nodded, turned into three afterimages and followed Keizaburo, heading towards the Wind Country.

The forest under his feet kept retreating. Kakashi turned his head and looked at Yusuke who looked relaxed beside him, but his heart couldn't stop trembling. He had only felt this situation in his angry father. This was the body's instinctive reaction when facing his inability to defeat his opponent.

In the end, curiosity in his heart overcame fear, and he asked:"Yusuke, how did you do it?! Your strength has improved so much in a short time!"

You know, in order to improve his strength and catch up with Yusuke, he has been exercising to exhaustion every day since graduation, but his strength has only improved a little, and Yusuke is obviously different from him, and his strength has obviously improved a lot.

The passers-by also pricked up their ears, wanting to know how Yusuke became stronger.

"You want to know?!"

Hearing this, Kakashi hadn't said anything yet, but the passers-by next to the two of them nodded their heads like rattles.

"Blindly practicing hard is not efficient. Sometimes you can achieve twice the result with half the effort by finding the right method or the right method."At this point, Yusuke turned to look at Kakashi and said,"Kakashi, although your practice during this period has been very effective, it has already hurt your body. If you continue like this for a long time, it will not be worth the loss!"

Kakashi frowned, obviously a little unhappy:"Why do you say that?!"

Yusuke said,"Six to eighteen years old is the golden stage of human development. This stage is also the fastest stage for the growth of ninja strength. Basically, after this age, the progress of ninjas will slow down and it will be difficult to improve their strength.

But Kakashi, you have practiced too much, and your body has been injured. You may not feel anything in the golden stage, but when you are older, there will be problems.

If you really want to become stronger, after this mission is over, you and the passerby come to me, and I will train you personally!"

The leader Hui Saburo also nodded:"Kakashi, Yusuke is right. There are too many ninjas who have practiced too much, which leads to a slow growth in strength after adulthood, or even a decline.

This is also the reason why ninja schools focus on theoretical knowledge and generally graduate at the age of twelve. This���That's why Konoha ninjas are generally stronger than other ninja villages."

Hearing what Yusuke and Keizaburo said, Kakashi realized that he seemed to have overtrained, but a large part of the reason for his training method was that he wanted to be tired and not think about his father.

After realizing his mistake, Kakashi also wanted to make changes. Looking at Yusuke, he remembered the useful technique before and said,"Okay, after this mission is over, I want to see how your method works?!"

"I promise you won’t be disappointed!"
