After frightening the demons and commanding the demons, the extremely powerful dark demon dragon was besieged to death. Perhaps because of his unwillingness to fate, or perhaps because of the blessing of the universe, the demon dragon would be reborn in Nirvana and return to the city one day. In his previous life, he killed hundreds of millions of creatures and committed heinous crimes, just to protect the demon world from peace and prosperity, but ended up with an unworthy ending. In this life, he changed his appearance and vowed to kill the demon world one day, kill all those who had bullied him, and regain the power of the demon dragon!
