Starting from Uchiha Obito

"He's a genius. Luckily he managed to stop it in advance... What?!"

Before the smoke and dust from the collision had cleared, the situation between the two people had reversed. The person who was originally dead was still alive, while the person who was originally alive was already dead.

Racial secret technique 1: Izanagi permanently gives up a Sharingan with three or more magatama as the price to eliminate a cause and effect.

Racial Secret Technique 2: Izanami permanently gives up a Sharingan with three or more magatama as a price to create a cause and effect.

(Note: The consequences caused by causal skills cannot be repaired by non-causal skills.)

If he just opened the Death Gate, Wang Jie didn't have to use it. At the moment he opened the Death Gate, he was sure that as long as he closed the Death Gate before his life was exhausted, his regeneration skills would be enough to keep him alive. But just surviving was not enough! Because the gap between the third and fifth levels was no longer something that the Eight Gates could make up for. Burning a life was not enough to cross the gap, but fortunately, the difference was not far.

In Mike's perspective, the boy activated a Life-Burning series of skills, and rushed over with an indomitable momentum at a speed far beyond the limit of his body's reaction speed. However, even the Life-Burning series of skills could not allow a person to win by jumping two levels, so the boy fell down in the last centimeter.

"He's a genius. Fortunately, he was strangled in advance... What?!" He just sighed, and before he could react, he saw the boy's body disappear. Almost at the same time, a boy who rushed towards him in the same trajectory stood in front of him, and the boy's hand directly blew up his brain, interrupting all his thoughts.

"Huh~ Finally dead. I don't know if my Sharingan can be restored. As for cause and effect, I don't know if the 4th level can feel the law of cause and effect." Wang Jie eliminated the red surge on his body, and sat down limply. At the same time, his right eye dimmed. The Mangekyō Sharingan, which had accompanied him to grow to this day and made great contributions, lost all its functions.

It is not dead. If a cell test is done, it is definitely still alive. It just can no longer play any role. The effect is similar to being sealed, but there is no way to unseal it.

Wang Jie doesn’t have much time to mourn for it now. He has only solved one enemy and there are still many enemies behind. The most urgent task now is to recover as soon as possible.

"I must make up for the loss." Wang Jie swore secretly. Although he didn't know how much attribute gain could offset the loss of a kaleidoscope, he felt that it was far from enough to plunder only 10% of a fifth-level strongman.

"You can actually kill a level 5? Are you really a level ?" When the smoke and dust cleared, Meng Guangzu came to Wang Jie and said in disbelief after arranging the rescue and defense tasks.

"Brother, I'll leave it to you guys from now on. I need to take a nap first." Wang Jie closed his eyes. His regeneration skill allowed him to open the Death Gate without dying, but recovery would take time. At this time, he urgently needed to go to the Naruto world to have a good rest.

"Hey~ You're still just a teenager." Seeing Wang Jie falling backwards, Meng Guangzu hurriedly caught him. This place was too close to the exit of the secret realm, so he picked up Wang Jie and moved him to a safe place.

Not only did the Holy Empire not send out a single fifth-level warrior, but the subsequent attacking forces also poured into the exit of the secret realm one after another after the agreed time. Although the battle between Wang Jie and Mike seemed complicated, in fact everything happened within 20 seconds, and Meng Guangzu had plenty of time to arrange his defenses.

Therefore, the people from the Holy Empire who rushed in later were like committing suicide, especially based on their confidence in the fifth-level strongman. The process of committing suicide this time was particularly long. However, these had nothing to do with Wang Jie. He had been sleeping. At the same time, in the Naruto world, Obito was also staring at the dim eyes in the mirror in a daze.

"Well, what should I do? I didn't prepare any colored contact lenses for the Sharingan. If I open my eyes, won't everyone be able to tell that I'm blind?"

Relying on his ability to regenerate severed limbs, Wang Jie tried to dig out his dim Sharingan after the aftereffects of the Eight Gates of Ninjutsu had passed. New eyes did grow out, but they were still a dull gray, and anyone with a discerning eye could tell that he was blind.

"How about asking Fugaku for a three-magatama one?" Obito scratched his head, regretting not preparing some three-magatama consumables for Izanagi earlier. The main reason was that he was too confident before, thinking that he didn't need to fight desperately no matter what the situation was, and the most he could do was to run away. But this time, he created an environment for himself that required him to fight desperately on the impulse, which was completely beyond Wang Jie's rational expectations.

Looking at the pair of gray and red Sharingan in the mirror, Obito suddenly had an idea.

Since it has been confirmed that the regeneration ability of severed limbs can regrow an eyeball, what if the eye I remove is not the blind right eye?

Just do it when you think of it. This doesn't require any medical skills, just be ruthless enough.

Obito used the transformation technique to cover up the abnormality of his right eye. Transforming oneself should be the simplest application of the transformation technique. Without anyone noticing, he successfully went out and bought all the things he needed.

He asked the shadow clone to remove his left eye and preserve it with a sealing technique. After waiting for about half an hour, his left eye grew out again. Then he asked the shadow clone to remove his dim right eye and put the left eye he had removed before into it.

As for the effect, it’s hard to judge.

"I have to find someone who can perform an eye replacement surgery on me." Probably because the replaced eye had not undergone any surgery, all the flesh could tell that the right eye was still empty, so the left eyeball was pushed out by the newly grown right eye, and the experiment failed.

However, Obito felt that this failure could be remedied, especially since the newly grown left eye was able to successfully open the Mangekyo again, and the Mangekyo did not disappear on the removed eyeball. Obito felt that his idea should be feasible.

Izanagi does not require the Mangekyō Sharingan, its activation condition is only the sacrifice of a three-magatama Sharingan. Judging from Madara's history, it doesn't even matter whether the three-magatama is his own. It's just that this skill is recognized as a causal skill by the system, which causes the regenerated eye to be unable to restore sight. But logically speaking, his right eye did not restore sight, it just replaced an eye that was not blind. In principle, it is the same as Madara having replaced his eyes beforehand.

So the success rate of this method is very high. The only problem is the selection of people. Who should he ask to help?

"Rin, please." After much thought, Obito finally found Rin Harano. As Tsunade's disciple, she must have the technical ability, and there was no reason for her to harm him.

"I, I have never had this kind of surgery."

"It won't be a big deal. My regenerative abilities are very strong. You don't have to worry about the details. Just replace this eyeball with mine and connect the main nerves and blood vessels. My body will automatically repair those details."

It didn't take Obito much effort to convince Rin to help. The two of them had been in frequent contact in the past few years. Although Obito had no intention in that direction, she was the goddess of this body in the original work after all, and even if there was no romantic relationship between them, he would not make the relationship too bad. Rin's identity as Tsunade's disciple was fought for by Obito. Seeing that Obito had lost one eye, it was not too difficult for her to just help with the surgery.

However, the two of them had no place of their own, so the operation was performed in Konoha Hospital. A rumor spread that Uchiha Obito had an operation in Konoha Hospital.

As for what the operation was, no one knew. Even when Tsunade asked, Hara No Rin didn't say anything and pushed everything onto Obito. Similarly, Obito didn't say anything on the Uchiha side, but neither of them denied the existence of the operation, which gave the outside world endless room for imagination.

Since no one noticed it afterwards, Obito's plan was naturally successful. The left eyeball that was replaced in the right eye frame was not destroyed. The eyeball came from his own and there was no rejection. Obito regained his sight. The only change was that he still lost the long-range attack method of Kamui.

Of course, there was some unexpected gain. After his right eye regained its sight, Obito found that the pattern in his right eye had changed. The original three sickle-like patterns turned into three overlapping diamonds. After testing, he felt that this should be the so-called Eternal Mangekyo. Even if the pupil power was not added, the use of pupil techniques would not consume the eyes. Of course, it was only the right eye that had changed shape. Even if the left eye was taken off and replaced, it still did not become the Eternal Mangekyo. This made Obito extremely curious. He really wanted to know what the difference was.

Unfortunately, he doesn't have a full-band force field detector now, so he can't see what the secret of the Eternal Kaleidoscope is for the time being.

"It doesn't make sense. They are both my eyes. Why does it become a kaleidoscope when I install the right one, but it's useless when I install the left one? Do I have to go blind once before I can replace it? That doesn't make sense. I was also blind once when I took my left eye off. No, I must go back and get it checked as soon as possible."

A day has passed in the world of Naruto. Wang Jie fell asleep while lying on the bed thinking. When he opened his eyes again, 10 hours had passed in the doomsday world. The Holy Empire failed to take back their secret realm exit. The key point was that all the level 5 strong men who came in were killed. They had no idea what kind of dangerous place this was. They didn't know whether they should continue to add lives to this hole or how much combat power they should send out. So after the first person ran back to report the news, the secret realm exit was calm for 10 hours, and the Holy Empire did not make any more attempts.
