What happened that night was the beginning of the massacre that would last for two weeks. Harnessing vital energy from the bodies of his victims, Mel didn't need to take time to sleep and waited for his wounds to heal as he wandered through the jungle regions.
It was five or six hours for the first two days, but once he realized the common features of the swarms, the carnage accelerated. They were able to store the energy of nature in their bodies; thanks to that energy, they could increase their physical development and experience regional changes, but it seems that none of them were able to use elemental transformation.
Mel's walls, which regenerated stronger as they took damage, were nearly impenetrable against non-elemental power attacks. Except for his eyes and genitals, his body was transformed into an impenetrable, invulnerable, and invulnerable weapon with no elemental energy.
