Naruto: My and Obito's mutual redemption

Yu Yan had the Immortal Fukasaku on his head. Following his guidance, the man and the frog came to a huge yellow waterfall... The closer they got, the more Yu Yan felt a strange energy pressing on his skin...

"Uh... that, Grandpa Immortal, I've been wanting to ask you since a while ago... what exactly is this increasingly strong strange energy...?"

Yu Yan scratched his cheek. He was not sure if this was the so-called natural energy, but this feeling of being oppressed was not very pleasant...

Fukasaku was shocked when he heard Yuyan's words, and said in shock: "You... can you feel the energy around you? This shouldn't be the case... it stands to reason that mortals who have never been exposed to immortal arts will never be able to feel this energy..."

"Uh... I don't know, but I can probably feel that the air around me seems to be getting more... sticky?"

Fukasaku jumped down from Yuhiko's head and landed in front of the stone platform below the yellow waterfall, with a meaningful look in his eyes...as if he was looking at a monster.

"Grandpa Immortal?"

"Ahem, I don't know what to say... You are the first person I have seen who can sense this power without having come into contact with natural energy. Although the natural energy of Myoboku Mountain is many times more concentrated than that of the outside world, it is not something that can be achieved under normal circumstances..."

As Fukasaku Sennin spoke, he began to explain what natural energy is.

Yu Yan remembered this part very clearly. Now, after hearing what Shen Zuoxianren said, he had a better understanding of this so-called natural energy...

"The combination of physical energy and spiritual energy can produce chakra... This is the foundation of ninja. And the fairy technique adds natural energy absorbed from the outside, that is, the energy contained in the atmosphere and the earth..."

Yu Yan pondered and nodded silently.

Seeing Yuyan's thoughtful expression, Shenren Fukasaku didn't disturb him. For a strange kid like him, maybe even learning fairy arts might not be too difficult?

After a while, Yu Yan sorted out all the theoretical knowledge, and now it was time to put it into practice.

"Well, although you are born with the ability to sense this energy, sensing it and utilizing it are two different things, so let's get started!"

Fukasaku looked at the yellow waterfall behind him and continued to explain, "Since you can feel it directly, we don't need to use this toad oil to assist, and we can start the second step directly!"

"The second step is..."

"You sit here and take off all your clothes!"

Although he knew the process, he still decided to take it one step at a time. It was his first time to practice this strange energy, so he must not be careless... He took off all his clothes and started to sit cross-legged in front of the stone platform under the waterfall to enter a state of meditation.

"Well... now don't move. Feel the energy with your heart and try to bring it into your body..."

Fukasaku Sage nodded and looked at Yuyan with satisfaction. Although this kid seems to be gifted, he is still very obedient... However, his body is very special, and the amount of chakra is as huge as that of a tailed beast. What's even more strange is that he can directly feel the natural energy... Is this also the perfect sage body of the Senju family at work? That's not right... You know, the sage body and sage technique are two different concepts...

With his mind full of doubts, Sennin Fukasaku decided not to think about these strange things for the time being. Since the boy in front of him was so powerful, maybe he could ask him to promote Myobokuyama more... Well, I hope the Wet Bone Forest won't have any objections!

Yu Yan had no idea what Fukasaku was thinking. He realized something more important... He felt that he had absorbed a lot of natural energy, and he could feel his soul power intuitively, but it seemed that compared with chakra, it was still far behind...

Shennin Fukasaku allowed himself to absorb a little and feel it first, but what about feeling... he did feel it.

As Yu Yan sat cross-legged and absorbed natural energy, Shenren Fukasaku suddenly realized that the natural energy around him was pouring into Yu Yan's body at an incredibly fast speed. This was too much! Shenren Fukasaku was shocked. This huge amount of natural energy was almost twice what he usually absorbed...

"Yuyan boy! Stop!"

Fukasaku pulled out a dog-beating stick from somewhere and hit Yuyan on the forehead...

"Ow!"

The sudden attack woke him up completely. Yu Yan covered his head, tears in the corners of his eyes, and looked at Fukasaku with a wronged look...

Fukasaku was also puzzled at this time. He seemed to have hit without seeing the situation clearly. After all, no matter how you look at it now... Xiao Yuyan seems to be no different from usual, and there are no obvious symptoms of toad transformation on his body...

"Eh? You just absorbed so much but not only did you not turn into a toad... but it's still not enough? Ahem... Listen carefully, Xiao Yuyan, you have to perfectly adjust the balance of the three energies! Only in this way can you successfully extract the fairy chakra... If you are not careful, such a huge amount will be very dangerous..."

"It hurts... I understand, Immortal Grandpa, I will be extremely careful!"

Seeing Yuyan in this state, Fukasaku breathed a sigh of relief. Sure enough, there was something wrong with this kid's body... Looking at him like this, has he ever been exposed to other energies? What kind of energy can be fused with chakra? I've never heard of it...

What Fukasaku didn't know was that Yuyan had already been integrating his soul power into ninjutsu intentionally or unintentionally in the early days. He was not clear about the definition of soul power, but it seemed to be different from the so-called spiritual energy... But even if he didn't understand it, it didn't stop him from using it.

Now that he has come into contact with the immortal arts, he is confident that he can perfectly balance the proportions of the three in his body... which translates to "33.3333...%" of each energy.

As long as the number that cannot be divided is repeated infinitely, it may get closer to the perfect sage mode.

After Yu Yan sat back down, closed his eyes and concentrated, he began to feel the energy around him again.

So this is natural energy? To be honest, this kind of energy is quite familiar to me. It’s a pity that I have never come into contact with it before. I have no idea that it is like this, and I never thought that this kind of energy is...

This meditation lasted for half an hour... Yu Yan was motionless. From the beginning when his body stopped moving, to now when his energy, spirit, and even heartbeat became extremely slow...

One step further is death.

No wonder it is said that one has to "die" first before learning immortal arts... Yu Yan stopped all functions of his body and only retained his soul power to sustain his life... From the outside, he was like a piece of stone, completely blending into the surrounding environment.

Although he closed his eyes, Yu Yan seemed to see the Immortal Fukasaku staring at him cautiously, and seemed to see the blue sky in the distance, the giant vegetation... and even the gravel under his feet, and the tiny particles in the soil could be seen clearly...

This feeling is like putting on a pair of clear glasses for my usual soul perception, changing the fuzzy perception to a particularly clear perception...

Ten minutes have passed since Yu Yan completely entered the "death" state...Sennin Fukasaku looked at Yu Yan, his heart was filled with great waves...He was told not to move, but this kid could actually directly understand the true meaning of "not moving"?

If he hadn't seen that natural energy was actively and continuously entering his body, Fukasaku would have even suspected that this kid was already dead...

Energy absorption became slower and slower...Finally, after another fifteen minutes, the absorption of natural energy was completed. Yu Yan felt a new chakra formed by the mixture of three energies in his body, and the ratio was accurate to 33.33%.

This was already close to the limit. When he adjusted the ratio of water and wind chakras, it was not this difficult. After all, it was adjusting three energies at the same time, and it was really difficult to control them accurately without a large amount of dissipation.

Body, mind, nature. The trinity, a perfect mixture, becomes Senjutsu Chakra.

His eyes slightly opened...all the functions of his body started to function again. In an instant, his vitality was completely restored, a large amount of vitality escaped from Yu Yan's body, and the surrounding grass showed visible growth...

"You kid... you really are..."

Sennin Fukasaku looked in the direction of Yuyan in disbelief.

The powerful sage chakra, the perfect fusion... and the orange eye shadow at the corners of Yuyan's eyes all told Fukasaku Sage that Yuyan had succeeded. And it was a perfect sage mode that far surpassed little Jiraiya.

Yu Yan turned his head and looked at the oil surface below the waterfall. Except for the slight orange eyeshadow-like facial makeup at the end of his eyes, his eyes did not even turn into "一"-shaped toad pupils, but only showed a light golden color.

"Grandpa Immortal... am I considered...successful?"

Yu Yan asked the complex-looking Fukasaku Sage, but Fukasaku just nodded numbly. It must be said... He entered the Sage Mode perfectly in less than three hours. He didn't know how to evaluate him.

"Well, that's perfect... The next step is to gradually become familiar with this power and use it in battle." Fukasaku thought about it, hesitated for a moment and said: "If possible, you can continue to work hard to be able to activate this mode anytime and anywhere, so that man and nature can be perfectly integrated!"

"Uh...I'll try my best!"
