Killer B had now successfully merged the Eight-Tails' chakra with his own, and chakra tails had already appeared. This should have been Tailed Beast Transformation.
"I didn't expect him to undergo Tailed Beast Transformation!" Ruri saw Killer B almost upon him, wrapped in a red Chakra Cloak with several chakra tails growing out behind him.
Killer B had now entered Tailed Beast Transformation, and his speed had doubled. Even with his Byakugan, Ruri could barely track his movements now.
But even though Killer B had entered Tailed Beast Transformation, not a trace of fear appeared on Ruri's face. Just as Killer B was about to reach him, Ruri softly uttered a few words: "Fire Mystery, Fire Flowing Flame!"
As Killer B rushed toward Ruri at high speed, he suddenly felt a burning heat beneath his feet. With the Tailed Beast Chakra Cloak around him, the heat did not feel that intense, but the soles of his feet still went numb.
Killer B's movements involuntarily slowed. Compared to just moments ago, he was now much slower, as though he were stepping on red-hot blocks of iron. Although the Tailed Beast Chakra Cloak protected him, he could still feel the heat coming through the soles of his feet.
"Damn it, what is this now? First ice, then fire. This is so annoying!" Killer B glared angrily at Ruri as he felt the heat travel from his feet to his head.
By then, the heat Ruri released had completely melted the ice, leaving the river's surface exposed.
Fire Flowing Flame channeled the power of the Flame-Flame Fruit through the soles of his feet, then radiated it outward from within, filling the entire river's surface with heat and turning it into his battlefield. Only by doing this could he gain the advantage.
