There are two ways. The first is to raise his own level so that his eye techniques can forcibly change reality. The second is to survive a few more rollbacks of time and eventually adapt by force, ignoring the very power of the time stream.
Actually, it's not that his dojutsu at the current level is unable to withstand the power of spacetime. It just can't take it in. The residual traces of the power of time were too insignificant, they couldn't even inflict fatal damage on him, but only rewound him. This power was too formless, leaving only a phantom mark on him.
He was only able to retain his memories because, after many rollbacks, the phantom traces continued to overlap each other until they finally activated the Izanagi. All objective and subjective adverse factors should be erased. Now, at the level of subjective perception, he was already aware that time was turning back. His eye techniques were, in fact, constantly active, but the time rollback left almost no traces, and he could not find the reality where his power was intact.
If it had been a direct lethal attack capable of wiping Uchiha Yue out of existence, his dojutsu would have worked instantly, distorting the reality of his demise. All that remained was to admit that going back in time was truly an annoying nuisance!
Therefore, Uchiha Yue was not going to avoid the rollback of time — on the contrary, he was ready to meet it with open arms. And so, when he swallowed the star, darkness descended again!
— As expected, it happened again! Uchiha Izumi sighed.
Everything was going exactly according to his forecast. Uchiha Yue could actually use a Shot Glass to tear apart tunnels in space-time and project his power. Who knows what degree of power he has reached if he has managed to destroy an entire planet in such a short time.
It's a whole planet!
Even the Sage of the Six Paths couldn't destroy the planet. Although there were techniques in the Shinobi world that could destroy the world, they took time to prepare, and the destruction itself was not instantaneous.
Boom!
A great battle broke out in the monastery of Ootsutsuki Isshiki. Isshiki from this world fell at the hands of two versions of himself from parallel worlds. With equal strength, how could two people lose against one?
After the death of their doppelganger, the two Ootsutsuki Isshiki, whose Karma was already fully revealed and was counting down to death, instantly found their carriers and were immediately reborn. Taking advantage of the fact that the planet had not yet been completely absorbed and destroyed, they rushed to save their lives.
However, their actions didn't make any sense. At the very moment when Uchiha Izumi died, the two fugitives, who had already reached outer space and were about to open the gates of space-time to leave the star system, froze like flies in amber, unable to move. Time has gone backwards.
The cycle has begun!
Uchiha Izumi continued to collect all kinds of data. Initially, he believed that this cycle would repeat itself until he defeated Uchiha Yue or forced him to stop his actions. However, after just a few cycles, a chilling picture appeared before his eyes.
"This."..
When darkness engulfed everything and his life ended, he woke up to find that he had returned to that very day, to a new point of preservation — the moment of entry into the third parallel world.
At that moment, the world should have been cloudless, and the sunlight should have been bright. But now, everything was shrouded in shadow, the sky dimmed, as if night had fallen!
And although this darkness appeared briefly and soon disappeared, Uchiha Izumi's pupils trembled violently.
"Not like that... It's not like that... There shouldn't be such a sky, such darkness!
A picture of the deathly darkness that had just enveloped the entire Shinobi world surfaced in his mind, plunging everything into oblivion. She was exactly like the one he saw now.
The world wasn't supposed to look like this! The sky wasn't supposed to be black!
— Time has rolled back, now the world should be bright... no...
He lowered his head, desperately trying to remember. Today was just an ordinary day. He didn't remember what the sky was like. Maybe he was just winding himself up? Maybe it really was cloudy today. No normal person remembers the weather for every day, the color of the sky. Maybe he's really panicking for nothing!
But was that really the case?
No, he immediately applied a special ninjutsu that allows him to extract memories from the depths of consciousness. At his request, Senju Tobirama and others developed this technique in one of the previous cycles — its creation required the efforts of many talents. With this jutsu, he could thoroughly recall everything he had ever seen, even a glimpse. It was thanks to him that he was able to record all this data.
Soon, the memories of that day flashed through his mind like a movie. He rewound time to the present moment.
The sky was clear, cloudless, and looked incredibly calm.
It's completely different from how he saw it just now.
— ...
He was silent for a long time. A chilling feeling pierced his heart. The reason he used to be so confident in himself was because of his ability to go back in time, and his almost endless margin for error. With endless time and endless cycles, even the most terrifying opponent would not be able to resist him.
But now, seeing this picture, he couldn't help but understand. Uchiha Yue... has gained immunity! This monster has started to become immune to his time travel!
There was no other way to explain why, after so many cycles, the world remained normal, and after that, darkness remained. There was only one possibility: Uchiha Yue had gained immunity to his ability. Maybe not complete, but that didn't add to his sense of security at all. Not full immunity now? And what about the future?
Uchiha Yue was alive, he could evolve. Previously, he couldn't resist his power! Who knows if over time, as the cycles continue, he will completely ignore the time loops and, like Izumi himself, retain his strength after the rollback. The main advantage of going back in time was that it turned living, constantly growing people into predictable NPCs who could be defeated.
Take Uchiha Yue, for example — he had unlimited potential for growth, but so what? As soon as he rolled back, his entire growth during this period was reset, while Uchiha Izumi remained unaffected. He could continuously accumulate knowledge and power, constantly improving, while time stood still for Uchiha Yue. After all, Izumi's power would continue to grow until he destroyed Yue.
Such a future may have been very far away, but it was predictable. But now... Everything was different...
