Nojuro Ryun showed a serious expression. This was a topic he was quite interested in.
Without a doubt, after a person gains chakra, their vitality improves.
For example, after Nojuro Ryun gained chakra, his physical recovery speed became at least twice as fast.
But vitality is not equal to chakra, because the vast majority of people cannot prolong their life after gaining chakra.
At the same time, chakra and vitality can be converted to each other to a certain extent. Chiyo's use of the Life Reincarnation Technique achieved this process.
It is just that this conversion process has severe losses, so much so that using the Life Reincarnation Technique is almost always a fatal result.
Ryun self-studying the Life Reincarnation Technique was naturally not to sacrifice his life to save others one day. He wanted to thoroughly research the conversion and utilization of vitality. Perhaps in the future, he could find a way to use chakra to slowly nourish his own vitality.
At that time, he in the real world would truly not have to worry about most injuries.
It is just that this process, as Ryun expected, was difficult to the point where Ryun had almost no clue.
[After a full year of research, you realize this ninjutsu also heavily tests a ninja's talent, and has high requirements for your yang release chakra attribute talent.]
[Konoha 67, you cannot find a way to improve your yang release chakra talent. But you think perhaps you can use the Medical Rejuvenation Technique to gather the yang release chakra of multiple people to supplement the chakra of a specific target.]
[Konoha 68, your concept is recognized by Tsunade. Tsunade permits you to conduct experiments, but only up to the stage of treating injuries. You succeed, naming the complete medical ninjutsu the Medical Reincarnation Technique.]
Ryun looked at the simulation result in shock. He did not expect he really managed to achieve something.
Although limited by talent, he could not accomplish all this by himself, the simulated experience from Sunagakure gave him the idea of not limiting himself to the Konoha ninjutsu system.
It seems in the future he should also visit different countries. Perhaps he could gain more special experience.
Even the Akatsuki organization... it seems not impossible to mix in there?
The simulation continued.
[Your medical ninjutsu is rated as S-rank by Tsunade, because even she cannot perform this ninjutsu by herself. At the same time, you are ordered by Tsunade not to teach this ninjutsu to others without permission. You gladly agree.]
[Konoha 68, Naruto returns from training. Many events occur consecutively in Konoha. Those you know about include the Kazekage rescue mission, the Tenchi Bridge battle, Orochimaru's death, and the formation of Hebi.]
[However, what you pay most attention to is the battle between Team 10 and the Immortal Duo. After learning that Team 10 was dispatched and Tsunade planned to send support, you volunteer to join the support team.]
[Tsunade agrees to your request. By the time your support team arrives, Asuma is already on the verge of death. Ino is treating Asuma with tears in her eyes, but her Mystical Palm Technique is already useless for Asuma whose internal organs are damaged.]
[You pull Ino away. Under Ino's shocked gaze, you begin to lead the treatment. You draw the technique's sealing array, having every ninja present stand at one end of the array, inputting chakra into the array.]
[You are responsible for controlling the array, performing the Medical Reincarnation Technique, converting all the chakra into vitality to keep Asuma alive. Apart from you, each person paid roughly half a year of their lifespan. You bore the vast majority of the pressure, paying at least ten years of your lifespan.]
Seeing this, Ryun could not help but sigh.
Perhaps only in simulation could he sacrifice himself so unreservedly.
When it came to reality, Ryun would most likely choose to hide his strength. Otherwise, such power of his would probably bring disaster.
However, he simultaneously swore to himself that he would not let himself or those around him fall into such dangerous situations.
Since he could research a ninjutsu like the Medical Reincarnation Technique, then in the future he would definitely research even more powerful medical ninjutsu with fewer side effects.
Just like how Tsunade and Naruto in the original story directly healed a whole village or even the entire Allied Shinobi Forces.
[You successfully kept Sarutobi Asuma alive, but you yourself fell unconscious due to excessive consumption of vitality.]
[When you wake up, you are already back in Konoha Hospital. You struggle to get up. Looking at your white-haired, gaunt face in the mirror, you cannot help but lament that now you are truly all white.]
Seeing this, Ryun's heart tightened.
In his last guidance instruction, he set it to use this opportunity to resolve the conflict with Ino.
If Ino still refused to see him under such circumstances, then Ryun would have no choice.
To preserve the result, he could only switch to simulating Tenten.
He just didn't know what the outcome of such an operation would be.
But just at that moment, the characters appearing in the simulation made Ryun's spirit jolt.
[Sarutobi Asuma has fully recovered after treatment by Tsunade. He brings the entire Team 10 to visit you. He expresses his gratitude to you and promises you are henceforth a benefactor of the entire Sarutobi clan.]
[The Sarutobi clan also retains its current strongest pillar thanks to your actions. Your status in Konoha becomes second only to the Hokage and the Hokage's advisors.]
[When Sarutobi Asuma bids you farewell and leaves the hospital room, under your deep gaze, Ino stays behind.]
[Ino does not dare to look at you. She just sits by your bed, lowering her head to peel an apple for you. Two close friends who used to talk about everything, meeting again after several years, seem to have already found no common language.]
Ryun licked his lips. Now he really wanted to give guidance, but he had no more guidance attempts left.
He could only place hope in his understanding of Ino being sufficient for his simulated self to say the words he most wanted to say now.
And this time, the simulation did not have any more surprises.
[You pluck a flower from the bouquet sent by the ninjas and hand it to Ino. Smiling, you tell her that no matter what, you will still often give her bouquets in the future.]
[Ino finally raises her head. Her red, swollen eyes are full of flowing longing. She throws away the apple in her hand, hugs you, and wails loudly, as if she were the one who had been wronged.]
[You are puzzled by this, but choose to hug and comfort her. Just as you are thinking about what to say next, Ino suddenly asks you a strange question: has your body recovered?]
[Fortunately, your recovery speed is fast enough now that you can simply master yang attribute chakra. This allows you to not miss this day of growth with Ino.]
[Ding, you and Yamanaka Ino have become a couple.]
Seeing this, Ryun's mouth fell open.
Was Ino really this proactive?
But what exactly was going on? What happened to Ino?
Ryun could not guess, but he knew he would probably see the answer soon.
