Instead of replying, Billy approached so fast that the blast of his speed made his body burn for a moment, and then he hit the enemy's face with his elbow. Before Uvish could even react to that, a portal appeared behind him, and he was hit by his own blast of energy.

"Unbelievable," Billy said. "You shouldn't fire your spells like a moron since they can be used against you like that. Are you stupid?"

Uvish clicked his tongue when he recovered from the damage. Despite the situation, he took that warning to heart and dashed at Billy. He tried to hit him with the palm of his hands, and then Billy blocked them. He used the dark and light cannon. Billy repelled the attack, but the impact on Uvish's body was so close that he also suffered some damage.

While Uvish's hands were healing thanks to the power of the life spirit, Billy's hands were dripping blood, and they were healing a lot slower.
