"Ichiro, who are you?" Seeing Hinata Ichiro interrupting his cultivation, Uchiha Itachi asked with a puzzled expression.

"Itachi, you've just managed to enter a state of selflessness!" Hinata Ichiro said, "Now, let's start the second step!"

"Good!" Uchiha Itachi said.

"Itachi, for you who have just started cultivating immortal arts, the important thing is not how long you stay in the state of no heart and no self, but to find a way to make yourself able to enter the state of no heart and no self at any time!" Hinata Ichiro said, "So, in the next time, once you enter the state of no heart and no self, I will reach out and pat you awake!"

"Then, after being woken up by me, you need to enter a state of heartlessness and selflessness again!"

"After practicing again and again, when you feel that you can enter the state of selflessness at any time, then we can end this step of cultivation!"

"Ichiro, I understand!" "Ichiro Uchiha said suddenly after knowing the reason why Hinata Ichiro woke him up.

After that, Uchiha Itachi cultivated again.

Once, twice, three times......

After dozens of times of cultivation, Uchiha Itachi finally completed the second step of cultivation.

Looking at the time, Hinata Ichiro said, "Itachi, it's not a few minutes until 9 o'clock at this time, and the subsequent cultivation will be postponed until tomorrow!"

"Good!" Uchiha Itachi said.

……

8 p.m. the next day.

"Itachi, tonight, I'm going to teach you how to feel and absorb the natural energy of nature!" Hinata Ichiro said.

"Good!" Uchiha Itachi said.

"Itachi, before I start tonight's cultivation, I'll use a special method to let you feel the natural energy in the natural world!" Hinata Ichiro said, "After you have felt what natural energy is, then tonight's cultivation will be twice as effective with half the effort!"

"However, the special method I have performed will open the chakra acupoint of your body, so don't resist. ”

"I see!" Uchiha Itachi said.

Seeing that Uchiha Itachi understood, Hinata Ichiro stretched out his left hand to gather the natural energy in nature.

After gathering a certain amount of natural energy, Hinata Ichiro spoke: "Itachi, stretch out your right hand!"

Hearing this, Uchiha Itachi directly stretched out his right hand in front of Hinata Ichiro.

When Uchiha Itachi reached out with his right hand, Hinata Ichiro's right hand made a sword finger and pointed at a chakra point in Uchiha Itachi's right hand.

In the next second, a chakra acupoint in Uchiha Itachi's right hand was opened by Hinata Ichiro.

Then, Hinata Ichiro slowly infused the natural energy gathered from the palm of his left hand through the chakra acupoint that had been opened in Uchiha Itachi's right hand and into Uchiha Itachi's chakra meridian system.

"Itachi, can you feel a surge of energy entering your chakra meridian system?" asked Hinata Ichiro.

"Yes!" Uchiha Itachi said, "Ichiro, I can feel a wave of energy passing through the chakra meridian system in my right hand in the direction of my dantian!"

"That's right!" Hinata Ichiro nodded and said, "Itachi, after I infuse all the natural energy gathered in my left hand into your dantian, you can feel this natural energy carefully!"

"Don't worry, this natural energy I have injected into your dantian will not cause damage to your dantian!"

"I see!" Uchiha Itachi said.

After Ighiro Hinata infused all the natural energy gathered in his left hand into Uchiha Itachi's dantian, Uchiha Itachi began to feel the natural energy in his dantian.

A few minutes later.

"Ichiro, it's okay!" Uchiha Itachi said.

Hearing Uchiha Itachi say yes, Hinata Ichiro said, "Itachi, you should know how much natural energy exists in your dantian!"

"Now, what you have to do is extract the same amount of mental energy and physical energy!"

"After that, it's like mixing mental energy with physical energy to extract ordinary chakra, you fuse mental energy, physical energy, and natural energy together!"

"After you fuse your spiritual energy, physical energy, and natural energy together to obtain the Immortal Chakra, you will release the Immortal Chakra in your dantian at one time with the 'Fire Escape Hao Fireball Technique'!"

"Of course, in order not to cause a large-scale forest fire, you'd better release the 'Fire Escape Fireball Technique' at the sky!"

"In addition, if you fail to fuse your spiritual energy, physical energy, and natural energy, I will take action to expel the natural energy in your dantian!"

"I see!" Uchiha Itachi said.

After saying that, Uchiha Itachi started to act according to Hinata Ichiro's wishes.

Hinata, on the other hand, opened his eyes and watched the movements in the Uchiha Itachi Dantian without blinking, so as to expel the natural energy in the Uchiha Itachi Dantian at any time.

Out of prudence, at first, the Uchiha Itachi was particularly slow to fuse his natural energy with his mental and physical energy.

But in less than ten seconds, the speed at which Uchiha Itachi fused his spiritual energy and physical energy with his natural energy began to accelerate.

After a while.

"Fire Escape?

The Uchiha Itachi, who had completed the extraction of the Immortal Chakra, first sealed his hands, and then turned his face to the night sky, spewing out a huge fireball.

When a huge fireball flew into the night sky from the mouth of the Uchiha Itachi, the forest and the night sky were as bright as day.

"Ichiro, is this the increase brought about by the immortal arts?" Uchiha Itachi asked with some surprise as he watched the huge fireball that completely exceeded his expectations fly farther and farther.

"Itachi, this is the increase brought by the immortal arts!" Hinata Ichiro said, "However, the increase you see now is only the tip of the iceberg - after all, the natural energy I have injected into your dantian is insignificant!"

Hearing Hinata Ichiro say that the increase he saw was only the tip of the iceberg, Uchiha Itachi's eyes lit up, and he couldn't wait to say, "Ichiro, let's start practicing tonight!"

"Good!" Hinata Ichiro agreed.

After agreeing, Hinata Ichiro sealed his hands.

"Ninja Technique, Multiple Shadow Clone Technique!"

All of a sudden, Hinata Ichiro summoned four shadow clones.

Because he couldn't understand Hinata Ichiro's intention to summon the shadow clone, Uchiha Itachi asked with a puzzled face, "Ichiro, why did you summon the shadow clone?"

"Itachi, although the natural energy is inexhaustible, for you who are feeling the natural energy for the first time, the natural energy in this place where we are is still a little thin!" Hinata Ichiro said, "So, my intention in summoning the four shadow clones is to gather the natural energy around you - so that you can feel the natural energy in the natural world more easily!"

"I see!" Uchiha Itachi suddenly said, "Ichiro, thank you!"

"Itachi, there's no need to say thank you to each other!" Hinata Ichiro said.

After that, Hinata Ichiro made his four shadow clones sit in the four directions of east, west, north and south with Uchiha Itachi as the center - in order to make the natural energy around Uchiha Itachi more intense, Hinata Ichiro's four shadow clones are only ten meters away from Uchiha Itachi.

After Hinata Ichiro's four shadow clones sat down, Hinata Ichiro looked at Uchiha Itachi and said, "Itachi, after last night's cultivation, you have been able to enter the state of no heart and no self at any time!"

"Now, you need to enter the state of mindlessness and selflessness once again - but this time you enter the state of mindlessness and selflessness not so that you imagine yourself as a part of the natural world, but so that you first slow down the flow as a human being, and then slowly reconcile your own flow into the flow of nature!"

"Ichiro, can you explain this more clearly?" asked Itachi Uchiha.

"Good!" said Hinata Ichiro, "Itachi, compared to the flow of nature, we humans flow much more violently!"

"If you want to make the flow of people in line with the flow of the natural world, you need to slow down the flow of people!"

"When the flow of people slows down to a certain extent, it will be at the same frequency as the flow of nature – and this is also the moment when people and nature are truly one!"

"And when you are truly one with the natural world, you will be able to clearly feel the natural energy in the natural world!"

"As for absorbing the natural energy you feel into your body, Itachi, when you can feel the natural energy in nature, we will talk about absorbing the natural energy. ”

"Ichiro, what is the flow of people?" asked Itachi Uchiha.

"Itachi, the so-called human flow refers to a fluctuation of energy emitted by the human body to the outside world!" Hinata Ichiro said.

"I see!" Uchiha Itachi said suddenly.

Seeing that Uchiha Itachi understood, Hinata Ichiro advised: "Itachi, when you reduce your flow, you must reduce it little by little, and don't drop it drastically all at once - only in this way will you not miss the flow frequency of nature!"

"Ichiro, I see!" Uchiha Itachi said, "I'll lower it little by little!"

Then, Uchiha Itachi sat down on the spot and began to enter a state of selflessness.

As soon as he entered a state of mindlessness and selflessness, the Uchiha Itachi began to reduce the energy fluctuations that his body emitted to the outside world.

Seeing this, Hinata Ichiro couldn't help but marvel at Uchiha Itachi's talent.

As time passed, the flow of the Uchiha Itachi became lower and lower, and at the same time, the flow of the Uchiha Itachi became closer and closer to the flow of nature.

A few more minutes passed.

Suddenly, Hinata Ichiro's eyes lit up, and a happy look appeared on his face - it turned out that Uchiha Itachi had finally reconciled his flow into the flow of nature.

At this moment, the Uchiha Itachi seemed to sense something, and no longer continued to reduce his flow, but maintained the level of the moment.

Seeing Uchiha Itachi do this, Hinata Ichiro thought to himself, "I finally understand why teachers favor students with outstanding talents!"

Thinking about it, Hinata Ichiro still reached out and interrupted Uchiha Itachi's cultivation.

When Uchiha Itachi woke up from his cultivation, Hinata Ichiro said, "Itachi, I just felt the waves of natural energy in nature!"

"Yes!" Uchiha Itachi said, "Ichiro, I just felt that there is a strong natural energy around me!"

"Itachi, the moment you felt the natural energy in nature, did you remember the degree of flow you had just slowed down?" asked Hinata Ichiro.

"Remember!" said Itachi Uchiha.

"That's good!" Hinata Ichiro said, "Itachi, it takes a certain amount of time to go from a state where you can't feel natural energy to a state where you can feel natural energy, and you need to shorten that period as much as possible!"

"However, since this is a long-term training process, you can cultivate yourself in the days to come!"

"Now, what you have to do is to allow yourself to enter a state where you can feel the energy of nature at any time!"

"Tonight, I won't wake you up repeatedly, but you have to practice this process repeatedly!"

"When you think you can enter a state where you can feel the natural energy at any time, I will not only recall my four shadow clones, but also disperse some of the natural energy gathered around you!"

"At that time, you need to feel the natural energy in your normal natural environment!"

"Okay!" Uchiha Itachi said, "Ichiro, I see!"

After saying that, Uchiha Itachi began to cultivate.

Half an hour passed.

"Ichiro, I did it!" Uchiha Itachi said.

Hearing this, Hinata Ichiro first recalled his four shadow clones, and then dispersed part of the natural energy around Uchiha Itachi's body.

After doing all this, Hinata Ichiro said, "Itachi, let's cultivate!"

"Good!" Uchiha Itachi said.

After that, Uchiha Itachi cultivated again.

By the time it was 9 p.m., the Uchiha Itachi was used to feeling the energy of nature in its usual natural environment.

……

On the evening of the third day.

Over the course of an hour, Hinata Ichiro taught the Uchiha Itachi how to absorb natural energy.

……

Fourth night.

Over the course of an hour of teaching, Hinata Ichiro taught Uchiha Itachi how to store natural energy in the dantian.

……

On the evening of the fifth day.

Over the course of an hour of teaching, Hinata Ichiro taught Uchiha Itachi how to skillfully extract senjutsu chakra.

……

On the evening of the sixth day.

"Itachi, when last night's immortal cultivation ended, you had actually successfully cultivated the immortal arts!" Hinata Ichiro said, "And the reason why I didn't announce the end of the immortal cultivation last night is because you still have a problem that hasn't been solved!"

"I still have a problem that hasn't been solved!?" Uchiha Itachi asked with a puzzled expression, "Ichiro, what other problem has not been solved?"

"Itachi, during the cultivation of immortal arts last night, when you entered the immortal mode, don't you think that the time you entered the immortal mode was too short?" asked Hinata Ichiro.

After listening to Hinata Ichiro's words, Uchiha Itachi said with a puzzled expression: "Ichiro, I found that the time I entered the immortal mode was too short, but this should be normal!"

Speaking of this, Uchiha Itachi seemed to understand something, and asked expectantly, "Ichiro, is there a way for you to extend the time for me to enter the immortal mode?"
