After giving Might Duy an affirmative answer, Nawaki closed his eyes and focused on treating him.
Despite the confidence on his face, Might Duy's condition was actually extremely troublesome for him. Unlike Naruto, who seemed to have cheat-like mastery over Yin-Yang Release capable of creating life, Nawaki would have had no solution at all without the system's assistance!
In fact, Nawaki had already encountered great difficulty when he had previously used Wood Release to absorb Might Duy's chakra.
He discovered that the chakra generated by the Eight Inner Gates was likely no inferior in quality to Wood Release chakra, making it exceptionally difficult to absorb. The Wood Release elemental giant had been his carefully prepared trump card, capable of subduing even a Jinchuriki in an instant. Yet the crimson dragon formed by Might Duy had forcibly pierced straight through the wood elemental giant! For Wood Release, which excelled most at absorbing chakra, this was simply inconceivable!
Furthermore, after Nawaki absorbed the Eight Inner Gates chakra into his body with Wood Release, he discovered that it could not be rapidly broken down and digested like ordinary chakra. This chakra possessed an intensely corrosive nature that could destroy cells on a microscopic level. Even Nawaki's Asura physique could not withstand it!
The moment this chakra entered his body, Nawaki felt a sharp, violent pain in his chakra pathways. If his control over chakra had not already reached a microscopic level, allowing him to swiftly mobilize another batch of chakra within his body to wrap around and protect his pathways, they would likely have soon become as full of cracks as Might Duy's.
Even so, Nawaki did not dare let this chakra remain in his body for long. He quickly found it another destination and dumped all of it into the God Tree
