Looking at the anticipation on Uchiha Itachi's face, Hinata Ichiro shook his head and said, "Itachi, I can't extend the time for you to enter the immortal mode - after all, your dantian can only store so much natural energy!"

Hearing that Hinata Ichiro had no way to extend the time for himself to enter immortal mode, the anticipation on Uchiha Itachi's face disappeared.

Seeing this, Hinata Ichiro spoke: "Itachi, although I can't extend the time for you to enter the immortal mode, I have a trick to shorten the interval between you entering the immortal mode again!"

Hearing this, Uchiha Itachi was stunned for a moment, and then asked, "Ichiro, what is the trick you are talking about?"

"Shadow clone!" Hinata Ichiro said, "Itachi, what I'm talking about is to use shadow clones to shorten the time between you entering Immortal Mode again!"

"In the future, if you are going to fight with others, then you can stay and summon a few shadow clones to absorb natural energy in the dark before the fight - when all the natural energy absorbed by the main body is consumed, as long as you recall a shadow clone, the natural energy absorbed by the shadow clone will be instantly replenished into the dantian of the main body!"

After Ichiro said this, Uchiha Itachi's eyes lit up, and he said, "Ichiro, the trick you mentioned is indeed a very practical and good method!"

"Itachi, if the trick I'm talking about isn't practical, then why should I say it!" Hinata Ichiro said.

Speaking of this, Hinata Ichiro changed his words and said, "However, although the trick I mentioned can make up for the shortcomings of the immortal cultivators in the battle who are unable to absorb natural energy, there is a special risk!"

"Ichiro, what are the special risks of the trick you're talking about?" asked Uchiha Itachi.

Hinata Ichiro looked at Uchiha Itachi and explained: "Itachi, since the amount of natural energy that your dantian can store is limited, therefore, when the several shadow clones you summoned are full of natural energy, you can only recall your shadow clones one by one to replenish the natural energy you have consumed, and you can't recall two or more shadow clones at once!"

"If you recall two or more shadow clones at once, then the only result you face is to explode and die—after all, your dantian can't hold so much natural energy!"

"However, I don't mean the risk of recalling two or more shadow clones at once – after all, the risk of recalling two or more shadow clones at once can be avoided!"

"And in addition to the situation of recalling two or more shadow clones at one time, there is another situation - two or more of the summoned shadow clones are forced to return to their original body due to accidents!"

"If there is a situation where two or more summoned shadow clones are forced to return to their original body due to accidents, then the only way you can face is to explode and die - this is what I call a special risk!"

"In other words, when you use the shadow clone to take advantage of it, if you don't want to explode and die, then you must ensure that your shadow clone will not passively return to the original body due to accidents!"

"Ichiro, you're right!" Uchiha Itachi said, "When I use the shadow clone to play tricks, I do want to make sure that my shadow clone will not passively return to the original body due to accidents!"

Speaking of which, Uchiha Itachi asked, "Ichiro, if I want to avoid a special risk, then what should I do?"

"Itachi, I don't have any good ideas about how you want to avoid special risks - I can't predict what will happen to your shadow clone when you're fighting others!" Hinata Ichiro shook his head and said, "However, I have a way to reduce the likelihood of your special risk!"

"Ichiro, do you have any way to reduce the possibility of me having a special risk?" Hearing that Hinata Ichiro has a way to reduce the possibility of his own special risk, Uchiha Itachi hurriedly asked.

"Itachi, if you have the ability to teleport from a distance, or if you have a psychic beast that can reverse psychics, then you can greatly reduce the possibility of your own special risks!" Hinata Ichiro said.

When Hinata Ichiro finished speaking, Uchiha Itachi's mind turned and he understood the meaning of Hinata Itachi's words.

But after understanding, a faint bitterness surged in Uchiha Itachi's heart.

Pursing his lips, Uchiha Itachi said with some loss: "Ichiro, although your method is very good, I can't do it at the moment!"

"Itachi, whether it's the ability to teleport from a distance, or a psychic beast that can reverse psychic, it's not something that can be done in a moment!" Hinata Ichiro said, "You can take your time in the future!"

"That's all there is to it!" Uchiha Itachi said.

"Besides, if you're not alone when dealing with others, then you can ask your comrades to help you take care of the shadow clones you summoned!" Hinata Ichiro said, "And if you're fighting alone, you can only summon a shadow clone to absorb natural energy—if only one shadow clone absorbs natural energy, then your chances of special risk are much lower!"

"Itachi, with your strength, as long as you don't intend to fight to the death, or fall into a heavy siege, I believe that the time of the two immortal modes combined is enough for you to deal with all the scenes!"

"Indeed!" Uchiha Itachi said, "If you have comrades, you can ask your comrades to help take care of the shadow clones I summoned to absorb natural energy, and if you are alone, you can also summon only one shadow clone to reduce the possibility of special risks!"

"In addition, if someone really intends to attack the shadow clone you summoned to absorb natural energy, then you can also let the shadow clone you summoned to absorb natural energy explode!" Hinata Ichiro said, "In this way, you can not only destroy the enemy, but also avoid special risks!"

"It's just that after the shadow clone self-destructs, it will not only make the natural energy absorbed by the shadow clone wasted, but it is also very likely to cause you to be injured - because the power of natural energy is extraordinary, therefore, if your body is not far from the location where the shadow clone self-destructed, then there is a chance that you will be indiscriminately attacked by the shock wave of the shadow clone's self-detonation!"

"However, compared to the deity's body explosion crisis, whether it is a waste of the natural energy absorbed by the shadow clone, or an injury, it is within an acceptable range!"

"Ichiro, you're right!" Uchiha Itachi agreed, "Compared to the deity's explosion crisis, these are indeed within the acceptable range!"

"Itachi, I've said everything I need to say, so that's the end of my teaching of your senjutsu!" Hinata Ichiro said, "However, if you have any doubts in the process of using senjutsu, you can always ask me!"

"Ichiro, I will!" Uchiha Itachi said.

"That's good!" Hinata Ichiro nodded, then looked into Uchiha Itachi's eyes and asked, "Itachi, have you already turned on the writing wheel?"

"Ichiro, I haven't opened the Sharingan yet!" Uchiha Itachi said.

Speaking of this, an indescribable expression appeared on Uchiha Itachi's face, and he said in a deep voice, "Ichiro, if I can, I really don't want to open the writing wheel!"

"Oh!?" Hinata Ichiro asked with a surprised expression, "Itachi, why is that?"

"Ichiro, I've already learned from Brother Shisui about the conditions for opening the eyes of the writing wheel!" Uchiha Itachi said, "So, I don't want to open the writing wheel!"

Hearing Uchiha Itachi say this, Hinata Ichiro understood what Uchiha Shisui and Uchiha Itachi said.

Hinata Ichiro looked at Uchiha Itachi and asked, "Itachi, the condition for Shisui to say that the writing wheel is eye-opening is not to witness the death of someone close to you, right?"

Uchiha Itachi was stunned at first when Hinata Ichiro knew the eye-opening conditions for Sharingan, and then reacted - since the establishment of the village in Konoha to the present, it is impossible for the high-level leaders of Konoha and the core members of the major families of Konoha not to know the eye-opening conditions of Sharingan.

"Yes!" Uchiha Itachi said, "Ichiro, that's what Brother Shisui said to me!"

"Itachi, you think so too?" asked Hinata Ichiro.

"Ichiro, after learning about the eye-opening conditions of the writing wheel from the mouth of Brother Shisui, I conducted a relevant investigation!" Uchiha Itachi said, "Judging from the results of the investigation, Brother Shisui is not wrong!"

"So, even if I don't think so, it's what it is!"

Looking at Uchiha Itachi, Hinata Ichiro weighed it for a moment and said, "Itachi, it's not wrong to stop the water, but it's not all about the water!"

"Oh!?" Uchiha Itachi asked, puzzled, "Ichiro, what do you mean by that?"

"Itachi, for the people of the Uchiha clan, the easiest way to open the Sharingan is to witness the death of someone close to you!" Hinata Ichiro said, "But the Uchiha clan wants to open the Sharingan, but not just to witness the death of someone close to them!"

"Ichiro, is there really another way to open the Sharingan of our Uchiha clan?" asked Uchiha Itachi.

"Of course!" Hinata Ichiro said, "Itachi, I don't need to lie to you on this issue!"

After receiving an affirmative answer from Hinata Ichiro's mouth, Uchiha Itachi couldn't wait to ask, "Ichiro, in addition to witnessing the death of those close to you, what other way does our Uchiha clan's writing wheel eye exist?"

"Emotional stimulation!" Hinata Ichiro said, "Itachi, the people of the Uchiha clan opened the writing wheel eye because they witnessed the death of someone close to them, and the essence of it is that the people of the Uchiha clan were strongly stimulated!"

"Since the opening condition of the Writing Wheel Eye is a strong emotional stimulation, then if the people of the Uchiha clan want to open the Writing Wheel Eye, they only need to let the people of the Uchiha clan bear this strong emotional stimulation, and they don't need to care whether the event that triggers the strong emotional stimulation is true or not!"

"Ichiro, although witnessing the death of someone close to you can cause strong emotional stimulation, I don't believe that the reason for the Uchiha clan's eye-opening is a strong emotional stimulation!" Uchiha Itachi said incredulously.

"Hehe!" Hearing that Uchiha Itachi didn't believe his words, Hinata Ichiro smiled and said, "Itachi, whether you believe it or not, strong emotional stimulation is the reason why the Uchiha clan opened the Sharingan, but this is an unchangeable fact!"

"Proof!" Uchiha Itachi said, "Ichiro, I need proof!"

"Itachi, the strong emotional stimulation is not my conclusion that the Uchiha clan opened the Sharingan, but the conclusion of the second Hokage!" Hinata Ichiro said.

"Ichiro, is it really the conclusion of the second Hokage?" asked Itachi Uchiha.

"Itachi, it's indeed the conclusion of the second Hokage!" Hinata Ichiro said, "In the eyes of the second Hokage, there is no family that has a deeper 'love' than the Uchiha clan!"

"But because of this, the Uchiha clan sealed their 'love'!"

"Once the people of the Uchiha clan understand the power of 'love', the feelings that have been sealed will be liberated, and then the 'power of love' that surpasses any other family will be awakened!"

"But this power is very difficult to grasp - there is a possibility that the strong and overly strong 'love' can get out of control!"

"After the Uchiha people who have learned about 'love' lose that strong 'love', their hearts will be replaced by hatred that is even stronger than before, and their temperament will change greatly!"

"When the temperament of the Uchiha clan changes drastically, it is often accompanied by a very special symptom!"

"Symptoms!?" Uchiha Itachi asked, "Ichiro, what's the symptoms?"

"Itachi, when people of the Uchiha clan lose their strong 'love' or feel pain for their own frustration, a special chakra will be activated in their brains, which will affect the optic nerve, and then change the state of the eyes!" Hinata Ichiro said, "This is the 'Spiritual Portrait Hitomi', known as the Sharingan!"

"......" Iga Ichiro finished speaking, Uchiha Itachi looked at Hinata Ichiro in a daze, and didn't know how to speak for a while.

Seeing this, Hinata Ichiro continued: "The second Hokage believes that the Sharingan will synchronize with the power of the heart, so that the strength of the individual will increase rapidly!"

"However, since the growth of the power of the heart is caused by hatred, as the power of the heart increases, so does the hatred!"

"Almost all those who have awakened strong feelings are swallowed up by darkness, and then fall into the evil way!"

"As the negative emotions increase, the pupil power will also increase, and the stronger the pupil power, the more powerful the people of the Uchiha clan will be!"

"In this cycle, there will eventually be an uncontrollable state - just like 'Madara Uchiha'!"

As Ichiro Hinata finished speaking, there was a silence at the scene.

After a while.

"Ichiro, are you talking about the conclusions of the second Hokage?" asked Uchiha Itachi with an ugly look on his face.

Although Uchiha Itachi's face was ugly, Hinata Ichiro still spoke without hesitation: "Itachi, what I said is the conclusion of the second Hokage!"

After receiving an affirmative answer from Hinata Ichiro's mouth, Uchiha Itachi's eyes darkened, and his body shook involuntarily.
