Sasuke is not too reluctant to turn his body into Hokage, and in the original plot, he didn't feel ugly because of the two ugly duck webbed wings behind him, so he can be said to be a handsome guy who has no idol baggage.

The two walked into the "Six Paths Cell" R&D center in the biochemical experiment area, and as soon as they walked in the door, Sasuke saw Yakushidou and Xianglin wearing white coats, standing in front of the test bench with anticipation, waiting for his arrival.

Next to the two of them stood a child of seven or eight years old with long hair, who was also wearing a wide and loose white coat that was obviously one size larger, with a beautiful and dignified appearance, and very unique eyes, showing an amber color, and the pupils were still vertical.

The more Sasuke looked, the more he felt that the child was familiar, as if he had seen it somewhere, and that the child exuded a gloomy aura that did not match his age.

As soon as he saw Sasuke, he greeted him as if he was very familiar: "Yo, Sasuke-kun, long time no see." ”

The voice was very hoarse and low, and it didn't look like a child of this age could make it at all.

"Orochimaru!"

The more he looked at it, the more familiar it became, Sasuke finally recognized him, and quickly turned his head and whispered to Naruto, "How did you let that guy out?" ”

Naruto replied in a low voice, "Senior Dou begged me for a long time, and the R&D center was really short of people, so let him serve his sentence and be a researcher at the same time." ”

"Is that okay?" Sasuke said: "He's a terrorist, staying in a key department like the Scientific Ninja Research Center, if it's an oversight and he causes an accident, it's going to be a big deal!" ”

Naruto shrugged and said, "He shouldn't be hostile to Konoha anymore, and he also made a pact with me that I will help him achieve immortality, and he will be my experimental assistant." ”

"How can that kind of person be trusted!" Sasuke frowned, "What if he does anything behind your back?" ”

Naruto pulled Sasuke back a few steps and whispered in his ear, "Do you remember that chakra eye you dug up from Danzou?" ”

Sasuke nodded.

"It's a very special kaleidoscope writing wheel eye that can perform a strange illusion called 'Farewell Heavenly God'......"

Naruto lowered his voice and said, "The other gods can modify a person's will, and the person who hates Konoha the most can become the guardian of Konoha in an instant." Orochimaru also thought that he had agreed with me to protect Konoha in the future because his wish for immortality had come true, but in fact, behind my back, I replaced the eye in the slot on Xiangri's forehead and quietly gave him a farewell god. ”

Sasuke nodded knowingly, looked at the miniature version of Orochimaru with a sincere smile on his face, looked at his face that was a little cute because of his youth, felt extremely weird in his heart, and asked, "How did he become like this?" ”

"Doesn't Orochimaru want eternal life?"

Naruto said: "I used the genes embedded in the cells of the lighthouse jellyfish to create a 'vessel' for him to live forever, and this body will 'molt' every 18 years old, and then return to the age of 8, a cycle of ten years, and it will never stop." ”

"Eternal life that can never be adulthood? Is that still a normal person? ”

Sasuke had a hard time understanding the thoughts of these scientists, and glanced back at the child's version of Orochimaru, and asked curiously, "Then is his body male or female?" ”

"Sexless......" Naruto said nonchalantly, "I don't think Orochimaru cares about gender, he won't get married and have children in the future, and he didn't think about adding gender functions and related organs when he made the container." ”

Saying this, Naruto leaned into Sasuke's ear again and lowered his voice, "If the immortal creatures can reproduce, it will be very troublesome. If Orochimaru inherits the immortal genes, after hundreds of thousands of years, all the ninja planets will be his descendants! I deliberately designed the 'container' with the characteristic of not being able to reproduce in order to maintain ecological balance. ”

After explaining why Orochimaru, who had been double castrated in both "spiritual" and "physical", was serving his sentence outside of prison at the Scientific Ninja R&D Center, Naruto let Sasuke lie down on the experimental table, and discussed with Yakushidou, Xianglin, and Orochimaru how to conduct this epoch-making human experiment of "making six immortals".

Several people said a lot of scientific jargon that Sasuke didn't understand at all, and there were several heated arguments, and finally Naruto decided on the experimental plan against the crowd.

With the plan in mind, Naruto came to Sasuke's side and explained to him, "The experimental plan has been decided, and we will use a stem cell transplant to replace all the bone marrow stem cells in your body with 'Six Paths of Embryonic Stem Cells'. ”

"Naruto, I can't fully understand what you're saying, can you briefly explain what you're going to do?"

Naruto said patiently, "First of all, I will first extract the bone marrow stem cells from your body to prevent your autologous stem cells from interfering with the replication and growth of the six stem cells, by piercing a steel needle into your intestinal bone and extracting all the bone marrow fluid from it.

Then, I will inject the 'Six Embryonic Stem Cells' into it to achieve replacement, and during the replacement process, I will input my chakra into your body, and you will open the eternal kaleidoscope writing wheel eye to maintain the output of pupil power and activate the chakra in your body, which can greatly reduce rejection and increase the success rate of bone marrow transplantation. ”

Naruto continued slightly apologetically, "The transplant process will be painful, but in order to ensure the success rate of the transplant, I can't use anesthetics, so you have to hold back." ”

"No problem!" Sasuke nodded and said, "As long as I can resurrect Itachi, I can endure any kind of pain!" ”

Naruto was a little silent, and silently began preparations for the bone marrow transplant with the Yakushidou and a few others.

In fact, even if the experiment can be successful, Naruto is actually 100% sure whether the newly created reincarnation eye can be cast, and the previous statement is just to trick Sasuke into the experimental bench.

The experiment had been theoretically proven, and Naruto was confident that he would transform Sasuke's Eternal Kaleidoscope Sharingan into the Eye of Samsara, but the Eye of Rejuvenation did not always have the same ability.

Just as humans have dominant and recessive genes, the genes of the Otsuki clan are expressed in different ways, and Nagato's reincarnation eye can control gravity and soul, and cast Vientiane Heavenly Guidance, Earth Explosion Heavenly Star, Shinra Heavenly Sign, and Outer Path-Reincarnation Innate.

Even if Sasuke evolves the Reincarnation Eye, the new ability he obtains is likely to be different from Nagato's Reincarnation Eye, and the rules of the world he controls may be space and time, and if it does not involve the soul realm, he may not be able to cast the Reincarnation Innate.

Although Nagato's filthy earth reincarnation is now living leisurely in Konoha Village with his friends, Sasuke can learn from him the super S-level forbidden technique of Outer Dao-Reincarnation Innate, but it is difficult to say whether he can learn it or not.

Naruto didn't plan to tell Sasuke this secret before the experiment began, so he could only pretend to be confused for the time being.
