In the Rinnegan, three black Tomoe spun wildly.
Madara Uchiha desperately manipulated Susanoo, trying to use his twin swords to block Shinsei's long sword.
But no matter how hard he tried, he could only watch helplessly as the enormous longsword slashed down on his Susanoo's wings.
A deafening roar echoed throughout the surrounding forest. Some small animals that hadn't had time to escape were even stunned into silence.
Madara Uchiha was also somewhat surprised to find a crack appearing at the base of the wings of his Susanoo.
What terrifying attack power! His Susanoo at its strongest state, and in his memory, almost no Ninjutsu could break through this defense, except for Hashirama!
And this brat named Shinsei possesses such immense power even with a casual strike.
The Senju Clan truly lives up to its reputation as a clan as powerful as the Uchiha, capable of producing such a figure.
As Shinsei swung his longsword again, the massive Susanoo had already turned around, positioning its blade in the path of Shinsei's attack.
Shinsei ignored the longsword that was swinging towards him and continued to swing his longsword forward.
The clash of swords that Madara Uchiha had been expecting did not occur. His Sharingan clearly saw what was happening.
The long sword, several tens of meters long, suddenly disappeared from Shinsei's hand. After he swung his Susanoo sword, the strange long sword suddenly grew out of his hand and continued to slash at his Susanoo.
With a loud bang, Shinsei's Instant Blade struck Susanoo's chest once more.
A crack several meters long instantly appeared on Susanoo's chest.
Madara Uchiha used the power of his enhanced eye to instantly repair the crack.
As long as it's not a large-scale shattering of Susanoo, these tiny cracks can be repaired indefinitely as long as the power in his eyes is sufficient. And now that he has just replenished his body's energy, he is infinitely close to his peak condition, so he doesn't care about such minor damage at all.
However, Madara Uchiha wasn't particularly happy. Instead, he looked at Shinsei, who kept flashing across the sky, and questioned him:
"Kid, why do you have the Mangekyō Sharingan in your eyes? Do you also have Uchiha Clan blood?"
Although Shinsei's Sharingan is blue, it's different from the traditional red Mangekyō.
However, as the former head of the Uchiha Clan, Madara Uchiha evolved from the Sharingan to the Rinnegan, and in terms of research on the Sharingan, no one in the world can match him.
He was absolutely certain that the fluctuation of that eye power was indeed the Mangekyō Sharingan. As for why it was blue, he didn't quite understand, which was also the reason for his confusion.
Shinsei gently flapped his wings and stopped in mid-air. He said to Madara Uchiha:
"I am a descendant of the Senju Clan, and I do not have Uchiha blood."
As for these eyes, they are related to my senior. If it weren't for that Black Zetsu who claimed to be my senior's will, who ambushed me and damaged my eyes, I wouldn't have been able to get a pair of Three-Tomoe Sharingan.
As for why it evolved into Mangekyō, I'm sure you, senior, know very well.
The union of Yin and Yang gives rise to the myriad phenomena of the universe. If our predecessors could evolve the Rinnegan through Hashirama's flesh and blood, then it shouldn't be a problem for me, a Senju Clan, to evolve the Sharingan into the Mangekyō, right?"
Madara Uchiha coldly, without refuting Shinsei's words.
He naturally knew about Black Zetsu's previous involvement in designing Shinsei.
When Black Zetsu reported to him that there were two people who seemed to have come from the future, he was initially unwilling to believe it, but later intelligence confirmed that this was very likely true.
To prevent the Eye of the Moon Plan from being exposed, he had Black Zetsu devise a plan to eliminate two people from the future—the boy with the eye in front of him and the girl with the Byakugan over there.
However, the plan failed, and with Shinsei's strength growing, the matter was dropped. He was old and limited by his health, so he had to change his plans and hide Nagato away.
He still didn't quite believe what the kid in front of him was Sharingan.
Theoretically speaking, since the Uchiha can absorb the power of the Senju to further enhance themselves, then similarly, the Senju Clan can also absorb the power of the Uchiha Clan to enhance themselves.
However, the Sharingan is so special that ordinary people simply cannot control it. Even for the Senju Clan, the idea of evolving simply by acquiring the Sharingan is wishful thinking.
Otherwise, given the millennia-long conflict between the Senju Clan and Uchiha Clan since their inception, this would have been discovered long ago.
He even suspected that the kid in front of him might have also used Hashirama's cells, otherwise, where would a kid of this age get such a huge amount of Chakra? Even Hashirama at the same age would never have had such a massive amount of Chakra.
The brief exchange allowed Madara Uchiha, with his extremely rich combat experience, to gauge Shinsei's approximate strength.
Although this kid is young, his strength is probably no less than mine at my peak before I had the Rinnegan.
If I had been born in the same era as this kid, there would be no story Hashirama.
For a moment, Madara Uchiha was filled with turmoil and many thoughts. His plan, which he had worked so hard for over the years, seemed to be coming to an end.
He understood that even now, having briefly regained his youthful body, it was difficult to say whether he could defeat this incredibly fast Senju junior.
Moreover, he could travel between two worlds, and even if he lost the battle, he could easily retreat back to the other world, while he himself would never have the chance to realize his ideals again.
He was somewhat unwilling, and an extreme anger welled up inside him.
Why is it that in this disappointing world, there will always be someone trying to stop me? Why not let my plans succeed and establish a nation of eternal peace?
Haha, hahaha!
Madara Uchiha began to laugh, his laughter growing increasingly arrogant.
He stood with his hands on his hips, his clothes and long white hair fluttering wildly as Chakra surged from his body.
After laughing, Madara Uchiha looked at Shinsei, who was gently flapping his wings in mid-air. "Boy, I admit that among all the enemies I have encountered, you are the fastest. Even Hashirama and I could not reach such a level at your age."
Even if the Rinnegan is destroyed, I will never tell you its whereabouts.
Since you've come to seek the Rinnegan, you must be from another world, bringing you immense pressure.
Even if my plans in this world fail, I will absolutely not cause trouble for my counterpart in the other world.
He will take my place and carry on the plan.
Now come on! Let's fight to our hearts' content!
