Demon King

The demon world was jointly created by the demon kings of the underworld after the war between immortals and demons. Unlike the Wizarding World, no outsiders can enter the Demonic World. A fallen prince accidentally entered the demon world. After experiencing family love and betrayal, he finally unleashed his inner rage. He almost overturned and destroyed the entire demon world! About to ascend to the underworld, he used the magic box to open the barrier between the devil and the outside world, escaped the surveillance of the underworld, and caused a bloody storm in the Fantasy Continent. After entering the underworld, he changed from a height of contempt for all things to a common man. He went all the way with hatred. Kill the Underworld Emperor, destroy the Immortal Lord, and finally become the Demon Lord.
