Sacrifice? I Am the Evil God You Summoned

I was reborn, but became a tied sacrifice on the altar of a fantasy world. Everyone under the altar knelt down and shouted: "Please enjoy, ancestors!" Seeing the haggard old man approaching with a ferocious smile, I suddenly sneered: "Do you know who I am?" The memory of being a giant of demons in my previous life awakened. I broke free from the restraints and turned the altar into a training ground. Overnight, I reached the top again, and the whole continent trembled because of me! The person who once bullied me knelt down and begged for mercy, but I just wanted to get her back who died for me. "When I take charge of reincarnation, I will make you come back again!"
