Kazuki didn't know what level of powerhouse Isshiki was. After all, during the Boruto era, power levels were relatively vague.
Isshiki's strength was definitely greater than Naruto and Sasuke's, and he was the Otsutsuki who pushed them into a bitter struggle. In this regard, he was much stronger than Momoshiki and Urashiki.
After all, those other Otsutsuki might not even be stronger than Sasuke and Naruto in a one-on-one fight, but Isshiki was clearly stronger than the two of them combined. And this wasn't even his true strength.
At this moment, Kazuki had a desire to fight Isshiki, as he was currently the most worthy opponent for him in the Ninja World.
As long as Isshiki was defeated, or even killed, and his remains obtained, it would be beneficial for everyone.
If Shibai's corpse could be acquired, Tobirama and Orochimaru could research it. If they were lucky, they might even develop Shinjutsu for others.
Kazuki had no intention of transplanting Shibai's cells into himself, nor did he plan to research Shinjutsu.
Since Shibai could do it, why couldn't he?
Don't forget, he had the combat arena. As long as he continued to grind, he would eventually reach Shibai's level.
It would be even better if he could continuously fight Kaguya. Her stats were good, but her combat awareness was too weak. For Hagoromo and others, Kaguya was immortal, but for Kazuki, she was not impossible to kill. He had methods to deal with Kaguya, it was just that Hagoromo didn't.
If Kaguya was truly immortal and indestructible, then she wouldn't need to worry about the Ōtsutsuki clan.
And this method, Kazuki had, and the Ōtsutsuki also had.
Kazuki couldn't go to other planets to continuously acquire Chakra fruits and follow Shibai's path, but he had his own methods. He just hoped the combat arena would be more generous and provide him with more Ōtsutsuki to fight.
Also, the Ninja World was currently too peaceful. Madara's whereabouts were unknown, and he hadn't caused any trouble recently, making him feel a bit bored.
Later, he could investigate Isshiki's whereabouts. If he could find him, he would deal with him.
Dealing with Kakashi was not difficult. Kazuki had already defeated Obito. After integrating Obito's Kamui, he had obtained the Kamui from the other eye after defeating Kakashi.
Defeating Hashirama was also not difficult. For others, Hashirama was an insurmountable mountain, but for the current Kazuki, defeating Hashirama was just a matter of a glance.
[Ding, congratulations for defeating Hashirama and obtaining Hashirama's Sage Body. Do you wish to fuse it?]
Hashirama's Sage Body, for ordinary people, was a dream come true, but for Kazuki, who had already reached Kaguya's level, it seemed to have little effect. Moreover, he had previously absorbed Asura's physique.
Although Hashirama was powerful and his physique had undergone an atavistic awakening, compared to Asura, he was probably still a little lacking.
It would be even better if the abilities dropped in the combat arena could be fused with others.
Some things, for Kazuki, were just better than nothing. But for others, the effect was extraordinarily significant.
Just like Hashirama's Sage Body, if Kushina acquired it, she would be able to use Sage Fox Mode.
If Mikoto acquired it, she might be able to follow his path.
This could completely create a second Hashirama in a short period, or even someone more powerful than Hashirama, which was not impossible.
In this way, Kazuki would be responsible for fighting strong opponents, and others could become stronger through this.
However, just as Kazuki was feeling disappointed with Hashirama's Sage Body and was fusing it, Kazuki felt his physique still strengthen, by about one-tenth.
For Kazuki, this was already a huge improvement.
One must know that Kazuki was now another Ten-Tails. Even if someone stabbed him through the heart, Kazuki could ensure his own survival and recover in an instant.
Yet, Hashirama's Sage Body still enhanced Kazuki's physique by about one-tenth, which was already extremely rare and valuable.
This proved that even if Kazuki already possessed similar abilities, as long as he continued to absorb and stack them, his strength could still increase.
Kazuki could continue to grow stronger in the future by relying on the battle space. If there were a few more Hashiramas, that would be great.
After fusing Hashirama's Sage Body, Kazuki's gaze turned towards Obito.
The remaining two, whether Obito or Hamura, were Six Paths level powerhouses.
Even though Obito was a Ten-Tails Jinchuriki and thus considered Six Paths level, to say that he could compare to Hamura would be an insult to Hamura. During his Ten-Tails Jinchuriki period, Obito couldn't use Kamui.
His consciousness entered the combat arena, and Kazuki looked at Obito, feeling a pang of regret.
If Chakra Edible Creation could be used within the combat arena, that would be great. Unfortunately, the combat arena didn't allow for loopholes.
There were no consequences for losing to an opponent and dying in the combat arena. Similarly, refining corresponding pills through Chakra Edible Creation in the combat arena couldn't help Kazuki get stronger.
Just seeing Obito, Kazuki felt a surge of displeasure.
'Worthless trash, you dare call yourself the second Sage of Six Paths?'
Obito had now regained control of his consciousness. Seeing Kazuki's sudden appearance, a trace of confusion flashed in his eyes, quickly followed by a jolt. His aura erupted, and his eyes filled with intense killing intent as he lunged at Kazuki.
