In a world called "Sanctuary of the Beasts", a young man is expelled from his clan for not being able to summon his contracted beast. Time and again, he finds himself caught in humiliating situations, being expelled from the mercenary guild union, the hunter guild union, and the adventurer guild union. With nowhere to turn, he decides to spend his last money on alcohol in an attempt to escape his harsh reality. When he wakes up, he regains the memories of all his past lives, especially his first life as the supreme dragon sovereign of this universe. He determines that he must find ways to advance in his cultivation and embark on his path of vengeance and conquest to restore balance to the universe or, perhaps, find a way to live a peaceful life.
