Ryūjin Jakka Had Yet to Reach Its Full Potential

Crimson flames engulfed Susanoo in layer after layer.

The violet-blue giant's arm kept melting, and its once-solid Chakra Blade twisted under the searing heat.

Black Zetsu continued,

"Compressing Yin–Yang Release to this extent takes an enormous amount of Chakra."

"An ordinary Mangekyō Sharingan couldn't sustain that expenditure. Even if its owner tried
