The enormous water bullet spewed from Kisame's mouth exploded in front of Rōshi, sending massive waves surging toward him, intent on completely engulfing him.
With nowhere left to retreat, Rōshi simply chose to face it head-on.
"Lava Release: Granite."
This was a large-scale defensive ninjutsu that covered the user's body. Ordinary ninjutsu could not penetrate the Lava Release: Granite coating the caster's body, and taijutsu attacks would instead be scorched by the high-temperature Lava Release.
However, Kisame did not need to break through Rōshi's defense. He only needed to extinguish the Lava Release covering his body.
"Sizzle, sizzle, sizzle..."
Massive waves wrapped around Rōshi's body. The instant they came into contact, the water was evaporated by the intense heat of the Lava Release, producing a constant sizzling sound.
But the Water Style: Great Waterfall Technique alone had generated an enormous amount of water. No matter how high the Lava Release's temperature was, it could not evaporate all of it.
"Rōshi, we can only use that move now." Seeing Rōshi about to fall into desperate straits, Son Gokū offered his advice.
"I know. There's no other choice."
At this point, Rōshi had been thoroughly countered by Kisame. That was precisely why Akatsuki had sent Kisame to deal with Rōshi, the Four-Tails Jinchuriki.
Kisame himself possessed a vast amount of chakra on the level of a Tailed Beast, while the ninja sword Samehada was the key to his formidable strength. Anyone struck by Samehada would have large amounts of chakra absorbed from them. During battle, the opponent would gradually weaken as their chakra dwindled, while Kisame's chakra would only grow greater. He was the type who grew stronger against stronger opponents, especially when facing enemies with immense chakra, such as Jinchuriki. Against them, Kisame's abilities could be brought to their fullest extent.
