Konoha: This Sasuke is not too cold

The country of snow, on an ice field.

"The art of psychic!"

Sasuke slapped the ground with one hand, the smoke filled the air, and the sand sculpture that he had not seen for a long time emerged from the smoke.

Onigiri shook his increasingly strong body and looked around blankly. One moment it was in the warm spring-like Fire Country, and the next moment it was in the extremely cold Snow Country.

The sudden change in temperature made it shiver unconsciously.

Onigiri looked forward, Sasuke's figure came into his eyes, and the three magatama in the scarlet eyes made his body tremble again.

"Don't move"

Sasuke's calm voice sounded, and the rice ball froze in place obediently.

Sasuke nodded with satisfaction, and the Rinnegan slowly appeared in his eyes. He formed a seal with one hand and closed his eyes.

Senjutsu chakra began to flow, and halos gathered under Sasuke's feet, turning into chains and spreading out.

There are seven chains, corresponding to seven different chakra attributes.

Seven chakra chains spread to Fantuan's feet and wrapped around Fantuan's feet.

Sasuke's chakra is very special. Because the immortal body is fully awakened, his body has strong compatibility and attraction to natural energy.

Natural energy + physical energy + spiritual energy. After the three energies are balanced, senjutsu chakra will be formed. Sasuke has maintained this so-called sage mode for a long time, so long that he couldn't reject the natural energy.

Magic chakra is harmful to ordinary people.

If one's body and mind are not strong enough to control natural energy, the end will be tragic.

However, based on the research on the immortal human body and the development and improvement of the Yin seal, it took two and a half months to create a sealing technique that allows ordinary people to have the opportunity to harness natural energy.

"Immortal magic. Reversal of the seal!"

Seven colored chains wrapped around Rice Ball's feet. The chains seemed to be submerged into the body. Under the skin, chakras as big as hair began to swim towards Rice Ball's heart.

The senjutsu chakra was swimming in the body. Although the rice ball felt a little uncomfortable, it did not feel any pain. It just stood silently and allowed Sasuke to do anything.

Chakra threads gathered from all sides of the body to the heart. The threads were twisted and twisted, condensing into strange-looking runes and entering the heart.

In the heart of the rice ball, a ball of colorful energy gathered. The energy was like a sphere the size of a grain of rice. The runes shrank one by one and were sucked into the sphere, and the sealed space was slowly taking shape.

Silk threads protrude from the ball and are connected to the blood vessels and nerves around the heart, integrating into one.

"Buzz!"

As the last rune submerged, the threads growing out of the ball had spread to every part of the rice ball's body.

Blood vessels, meridians, flesh and blood, skin...

They blend completely into the rice balls.

As the heart beats, these threads come alive.

Wave after wave of weak natural energy was extracted from the world and entered the body, and finally it was all sucked into the sealed space.

After the transformation, grinding, and dilution of the sealed space, these natural energies become soft and docile, and are integrated into Onigiri's body along another part of the chakra thread.

"Success!"

After sensing it for a while, Sasuke opened his eyes. A drop of sweat slid down his cheek, but he couldn't hide the joy in his heart.

The Immortal Technique, Reversal of the Seal, was inspired by Sasuke's two and a half months combined with some books, and was improved little by little from the Yin Seal.

Just like its name, its function is to extract natural energy, and after the reversal and grinding of the seal, the originally violent natural energy becomes suitable for the body to absorb.

This reversed energy is very similar to Senjutsu Chakra, more biased in nature but different in bias.

The increase in senjutsu chakra is rapid and efficient.

In comparison, Reversal Seal is more like a growth item.

It integrates with the body without distinction, absorbing natural energy and feeding it back to itself.

As more and more natural energy is absorbed, the body and seal will become closer and stronger, and the efficiency of transformation will become faster.

Theoretically, as long as there is enough time, it can even raise an alternative fairy body by devouring natural energy.

However, this time will take a long time, maybe 50 years or 100 years.

However, once the reversal seal is stamped, it is very simple for the body to break through the limitations and gain a longer life, just like those so-called immortals in the Three Holy Lands.

Of course, the requirements for performing the technique of reversing the seal are so demanding that they are almost abnormal.

Based on the senjutsu chakra, the seven attribute framework, the samsara eye and the color of seeing and hearing can truly control the chakra in a subtle way, at the cost of almost draining most of Sasuke's chakra to create such a seal.

How much chakra does Sasuke have now?To be honest, even Sasuke himself doesn't know because there is no accurate data comparison.

Sasuke took a deep breath and felt a little weak in his feet. He had never experienced the feeling of lack of blue since he merged with the immortal body, and now he recalled that feeling again.

Sasuke let go of his body's suppression of natural energy, and in an instant, a large amount of natural energy swarmed in, desperately drilling into his body.

The chakra missing in the body recovered quickly, but the depleted mind did not recover so quickly.

Rubbing his somewhat swollen temples, Sasuke looked at the motionless rice ball with his eyes closed.

The first few days after the reversal seal is planted are the most dramatic times. With every breath and heartbeat, the body becomes stronger. It may take three or four days to recover from this state.

Moreover, the reverse seal of Onigiri is special because there is no chakra in Onigiri and he does not possess high intelligence, so Sasuke would use this extremely harsh method.

If it is used by a ninja, it is much simpler and does not require so much effort.

"Have a good rest, I'm looking forward to your transformation." He touched the rice ball's head, and looked at the rice ball whose eyes were still closed as if he was in a deep sleep. Sasuke also turned and walked back.

He spent too much energy helping Fantuan plant the reversal seal and needed to take a good rest.

Moreover, in addition to this, Sasuke also needs to prepare something else. Hinata's birthday will be in half a month, and he plans to go back.
