In the end, he was beaten away by the blackened male protagonist and his soul was scattered. After Luo Huan's time travel, he took a nap and slept for eight years. He didn't have the time to do anything bad. The pitiful and aggrieved brat he once was has grown into a fearsome demon king. And he, the master who should have been taught a lesson by the male protagonist to death... The male protagonist built him a golden house in the devil's palace deep in the devil world.
