Shinra knew well that even if he wouldn't die from this attack due to the regeneration and crazy survivability talent that came from the Batto Batto no Mi, Model: Vampire, which gave him an almost immortal-like creature, but he would definitely lose, and by then, what would happen to Robin and Carina?
He knew that he was too arrogant, thinking he had the ability to fight one of the Four Emperors, especially given his extensive experience and the numerous famous characters he had defeated one after another.
Even Rayleigh wasn't his opponent, but how old was Rayleigh?
Meanwhile, Kaidou was at his prime; he was at the age when he was at his strongest!
As he was at his most desperate, Shinra saw the scenery before him change and return to the moment before the attack.
'Huh?'
Was it a dream?
Shinra felt his mind overloaded as the information on his surroundings became so detailed that he could tell the voices, expressions, the changes of air, terrains, and everything within this world clearly.
'No, it isn't a dream.'
Instead, it was the ability of Observation Haki that had been developed to its limit.
In other words, foresight.
Yes, Shinra wasn't unfamiliar with foresight, as it was an ability that was owned by Narumi Gen when he wielded the Weapon Number 1 in the world of Kaiju No. 8.
However, this ability wasn't limited to the world of Kaiju No. 8. Instead, in this world, as one's Observation Haki was developed to the limit, they would be able to catch a glimpse of the future, or, so-called, the foresight.
While Shinra was dumbfounded as he never expected to awaken this ability by ability, he wasn't surprised since his Sharingan enhanced his vision to the limit, and he also had experience using the foresight with Weapon Number 1 on the world Kaiju No. 8.
More importantly, Shinra's opponent was Kaidou-sensei, the one who taught Luffy to infuse the Supreme King Haki into his attacks and also helped him to awaken the Nika Nika no Mi.
This was the reason why Shinra said before that Rayleigh wasn't a good teacher.
When Rayleigh taught Luffy for two years, the gains that Luffy gained from two years of training were less than what he got from being beaten by Kaidou.
In other words, if one wanted to become strong, then one should be beaten by Kaidou!
As Shinra was about to be beaten by Kaidou, somehow, he understood why he could awaken this foresight ability.
Yet, while feeling amazed by Kaidou-sensei, it didn't mean that he had escaped from the danger. Instead, even if he could catch a glimpse of the future, it didn't mean that he understood that it was impossible for him to dodge this attack.
Once he was hit, everything was as good as over.
Kaidou's attack was clad in the Armament Haki and the Supreme King Haki, causing all the abilities that Shinra had to be nullified, and he would be hit by pure damage caused by someone who was called the Beast.
Even Luffy, with the body of rubber that should be immune to blunt attacks, was smashed and defeated, so what about Shinra?
Shinra might have the Bane Bane no Mi, an ability that gave his body a spring-like trait, making his body work similarly to a shock absorber, and made his body immune to blunt attacks like Luffy's, but even so, it was meaningless in front of Kaidou's attack!
So, what should he do?
Even if he caught the 0.5 seconds in the future, it was meaningless!
Yet, even so, he didn't give up!
At this moment, his head became sharper, everything moved in a slow manner, and his body moved in a way that he wished to be.
If Kaidou's Haki could nullify his power, then Shinra could also cover his entire body in a combination of the Armament Haki and the Supreme King Haki, which would erase the nullification effect from Kaidou's attack and maintain the shock breaker-like effect on his body.
Yet, even so, there was a limit to what his shock absorber-like body could do.
So, should he run?
Twisting his body, running away, whether it was by turning into a bat, soaring into the sky, transforming into gas as he dispersed, or digging deep into the earth as he became sand, everything, all of that was meaningless before Kaidou's attack.
So, he knew well that he should accept this attack!
Yet, even if he decided to accept this attack, letting himself be hit, he should do it in a way that wouldn't hurt him.
No, it was impossible to be unscathed from this attack, yet it was possible to reduce the damage caused by this attack.
Ability might be useless, but what if he used something else?
If ability was useless, then he would use Haki and martial arts!
When everything was set up, his Haki that shrouded his entire body like armor changed its form into a calm, soft lull. Similarly, his body was no longer tense and became as flexible as paper, even water.
Inwardly, Shinra was glad that he had learned the Kami-e, one of the Rokushiki that gave his body a property similar to paper or a feather, which made his body flow along with the impact instead of accepting it.
Also, the martial arts that he had mastered in the world of Kengan, Water Stream Rock Smashing Fist, even if he thought that it was quite meaningless to be used in the world of One Piece before, started to become useful at this moment!
'Oh?'
Kaidou, who saw the change in Shinra's eyes that was filled with despair before, became filled with determination and hope, making him amused.
What could you do?
In front of the overwhelming power, everything was meaningless!
The metal mace that emitted a pressure that would shake the space, the earth, and everything was smashed into Shinra!
The rumbling lightning tore and destroyed everything!
Their hope at this moment was so fragile, like a fire on a candle, flickering, almost dying!
Only, as the mace was connected to the blade instead of the force of resistance that Kaidou expected coming from Shinra, it gave him a bad feeling.
Shinra's eyes were red, and his arms burst, showing his red muscles as his bones cracked, seemingly about to shatter, yet even so, his eyes were sharp, and the pain woke him, forcing him to raise his focus to the limit before he let the force behind Kaidou's Raimei Hakke to flow on his broad back—
Crack! Crack! Crack! Crack! Crack!
Shinra endured the pain as his bones broke and his muscles were torn, focused further on softening his body.
Softer! Softer! Softer!
Yet, even so, no matter how much he tried to soften his body, the impact still shook him and burst his organs.
As Shinra could also master the internal destruction with the Armament Haki, naturally, Kaidou could also do the same. However, he knew that he couldn't fall since if he fell, then he would lose everything.
His eyes lacked focus, blood kept pouring out from his eyes, nose, and all of his orifices, seemingly on the verge of crumbling between his consciousness, till all of a sudden, his senses were heightened further so that he could feel his entire body, feeling everything to the point of his cells.
Then—
All the environment in his surroundings turned into a viscous, dark-red substance resembling blood.
No, it turned into blood with enough amount to form a massive pool and completely cover the battlefield.
At the same time, all the blood in the surroundings and the souls of those who were about to disappear were absorbed into him as his appearance changed with flaming dark hair and crimson dark shrouds with points resembling the stars on the Milky Way, regenerating all of his wounds—no, instead of focusing on healing himself, he should focus on this attack!
Shinra ignored his wounds, erasing all the unnecessary information from his senses, and even shut down those that he didn't need, such as vision, taste, hearing, touch, and smell.
Abandoning all of those things, he concentrated the strength left over. All of his flesh. All of his brain. All of his blood. All of his cells, everything from them. He mustered all the personal vitality, stamina, magic power, and potential he had and perfected all the mistakes in his technique until finally, he was able to redirect all the force of Kaidou's attack into his own attack!
"Horizon."
His voice was completely lacking emotion as he launched the crimson black flaming blade that was filled with the force of Kaidou, which was combined with the force of his slash, the Armament Haki, the Supreme King Haki, and lastly, the Awakening power of the Mythical type of Zoan!
Slash!
Kaidou widened his eyes as this blade cut his mace and his body!
BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMMMM!!!!
