Yeyu knew very well what the First had been like.
Back then, the First Great Ninja War had created the Valley of the End.
In the past, Yeyu would have thought that was godlike.
But now, he didn't think it was anything difficult.
So it didn't impress him much anymore.
Even so, no one could force Yeyu to show his full strength. He hadn't even revealed a tenth of his power.
Ever since he had fused with all of Akainu's power, he had found that he could learn anything incredibly quickly, and the chakra within him had kept growing.
At first, Yeyu hadn't thought anything of it.
After all, Akainu's power had been formidable to begin with.
But later, his chakra kept increasing, and he learned ninjutsu faster and faster. No matter how difficult a technique was, he could master it at a glance.
Medical Ninjutsu, for example, wasn't something one could learn instantly just by having great talent and powerful chakra.
But Yeyu had done exactly that.
Recently, he had realized that his power was extraordinary.
Had he truly fused with Akainu's power, or had he fused with something far more incredible?
If he had only fused with Akainu's power, he absolutely shouldn't have been able to reach this level.
Perhaps combining it with the power of this world had caused his own strength to undergo a qualitative change.
Whatever the reason, it didn't seem to have any downsides for him.
After leaving the Third Hokage's room, Yeyu went to Neji's.
"Are we starting?"
When Neji saw Yeyu, he asked seriously.
Sasuke stood beside the bed, looking equally serious.
Yeyu calmly walked over to the bed and said softly, "Lie down."
Once Neji had lain down, Yeyu raised his hand. A dense mass of medical chakra appeared around it.
