Overcoming the Beast

Long ago beast and humans were living together in harmony. But all changed the demons broke through dimensions and attacked. They killed and spread chaos. The beast divided into two. One faction joined the humans while the other allied with the Demons. The humans and beast formed contracts to cultivate together to grow stronger faster. Through many sacrifices they banished the demons from the world. Now millions of years later. In a small town a boy was born. He spent his life in pain, misery and war. Through the worst of fates he was killed by his own beast. He was given another chance by mysterious means and was brought back in time. "Revenge will be so... sweet."
