My Power Assimilates All Things

After awakening the fusion power, I was sent to the battlefield I thought I was. On the battlefield, I found a camp with my companions, but it turned out to be just a canteen for the demon tribe. When I thought I had escaped, I was surrounded by monsters During the battle, my superpower went berserk and then merged with the demon clan and turned into a monster. Following the memories in our minds, we came to the Monster Clan Border Wall Learned the whole truth It turns out that the war has ended long ago. The places where we lived and fought were just the hunting and breeding areas ceded by the human race to the monster race. Next we have to survive in the demon clan's territory.
