Fortunately, it was only Asura in his youth. The tactical system of that era had not yet taken shape, and even with powerful stats, he might not have been able to perfectly unleash them.
The tactical system was developed in the Ninja World over thousands of years through continuous battles. When fighting people with similar stats, today's ninjas are definitely stronger than the ancients from a thousand years ago.
Kazuki wondered if Asura of that era could manifest a several hundred meters tall wooden statue. If so, he might not be able to defeat him at this stage.
The Flying Thunder God Technique is theoretically very strong, but in the combat arena, it will be greatly weakened. If it's a large-scale ninjutsu, he will be very passive, as the combat arena has limited range.
Kazuki entered the combat arena and found that he had exited Sage Mode.
He immediately began to absorb Natural Energy, attempting to quickly re-enter Sage Mode. At the same time, he silently sensed the aura of Asura opposite him, unable to help but click his tongue.
Kazuki's Chakra reserves were already very high, but Asura's Chakra reserves were even higher than his, at least ten times his own.
What a terrifying number! This undoubtedly meant he had over 150 units of Chakra.
Perhaps only Hashirama in his peak would be qualified to compare Chakra reserves with Asura.
Even Naruto, before receiving the Six Paths Power, and not counting the Nine-Tails's Chakra, couldn't compare to the youthful Asura.
The key is that Asura doesn't seem to have reached his peak state yet. It seems that in terms of physique alone, Asura is superior to Hashirama.
"Big brother? No, you are not big brother."
Asura on the opposite side was stunned when he saw Kazuki.
He felt a familiar aura on Kazuki, something he would never mistake. But why didn't the other party look like big brother?
Soon, he saw the three-tomoe Sharingan in Kazuki's eyes. Wasn't that big brother's eyes?
Could it be that someone was impersonating him?
Thinking of this possibility, Asura leaped towards Kazuki, punching towards Kazuki's face. Kazuki was still absorbing Natural Energy and quickly raised his arms to block.
The moment the fist struck his arms, Kazuki felt a surging force coming from his arms, pushing him back over ten meters.
"What terrifying strength, truly a Sage Body."
Kazuki prided himself on his physique already beginning to revert to its ancestral form, considering it a youthful Ōtsutsuki physique. But compared to Asura's Sage Body, there was still a huge gap.
"However, this makes it more interesting."
Kazuki's face showed his excitement, and the tomoe on his body appeared as he entered Sage Mode.
"So, do you also wish to dance?"
After speaking, Kazuki, enveloped in shimmering Lightning Chakra, charged towards Asura.
Asura felt the killing intent on Kazuki's body and became even more certain that although the other party had the Sharingan and an aura almost identical to Indra, he was definitely not Indra. Indra could not possibly have such killing intent towards him.
Immediately, Asura also erupted with powerful Chakra and engaged Kazuki in battle.
Kazuki, after entering Sage Mode, was slightly inferior in strength to Asura, but due to the Lightning Release, his speed was far superior to Asura's.
Kazuki was already very satisfied to be able to accomplish this. After all, he was only ten years old, with two months left until he turned eleven.
But Asura looked to be fifteen or sixteen years old, so there was a clear age difference between them.
Regarding this, Kazuki stated that he didn't cheat. He was able to achieve this entirely through his own efforts.
Bang... Bang... Bang...
The sounds of their fists and feet clashing continuously echoed, and as their battle continued, the Chakra bursts at the moments of their collisions quickly caused the ground of the combat arena to begin to crumble.
But both Kazuki and Asura grew more invigorated as they fought.
Kazuki kicked Asura in the abdomen, and Asura also landed a punch on Kazuki's chest.
Both flew backward. After landing, Kazuki rubbed his chest, which was aching. If nothing unexpected, his ribs should be broken.
But looking at Asura opposite, he noticed that he was clearly injured, but in no time, Asura recovered. Indeed, the Sage Body's recovery ability was not something ordinary people could compare to.
Even Kazuki's current physique was not enough.
Kazuki finally understood Madara's past misery. His strength was by no means inferior to Hashirama, and his destructive power was even subtly greater than Hashirama's.
But any damage he inflicted on Hashirama, the latter quickly recovered from.
He would expend considerable effort to inflict some damage on the opponent, only for the opponent to quickly recover.
Who could understand such misery?!
Although the opponent's recovery required considerable effort, it ultimately could not compare to his own consumption.
Indeed, the Sage Body is disgusting.
"However, it's time to fight a bit more seriously."
Through the previous battle, Kazuki studied Asura's fighting style and found that while Asura's taijutsu was very strong, belonging to the ancient era, it wasn't as practical as it is now.
Asura's fighting style could be studied, but there wasn't much worth studying.
A Sage Art: Wind Release: Rasenshuriken appeared in Kazuki's hand.
Asura warily watched the ninjutsu in Kazuki's hand. This ninjutsu seemed very interesting, and he felt it would be very suitable for him to study it thoroughly later.
However, if hit by this ninjutsu, even he would be in mortal danger.
Yet, before Kazuki could get close, a special spatial fluctuation appeared in Kazuki's hand.
Asura then felt another crisis approaching, as a space-time jutsu mark appeared from his chest, and a Sage Art: Wind Release: Rasenshuriken suddenly appeared in front of him.
Asura quickly retreated, trying to dodge the attack, but was still caught in the blast.
Ultimately, he lacked a bit of combat experience.
Kazuki admitted that Asura was the strongest person he had ever seen, but the other party had very little combat experience, probably having few life-or-death battles.
This was different from a ninja. Asura couldn't even imagine a jutsu like the Flying Thunder God Technique.
Indeed, the wicked Tobirama was the most insidious.
Asura, blame it on the naturally wicked old ghost Senju among your descendants.
