Five hundred years ago, the demons invaded, and the human race fought with them for several years. Fortunately, the war god Wushuang appeared out of nowhere, and exorcised the demons in the extreme south of the continent. Seeing that victory was imminent, the war god died on the battlefield for unknown reasons. Five hundred years later, the demons are ready to take action; a young man in the extreme south was sealed in a temple and became a monk because of his will to kill. Is he the reincarnation of the God of War? Or is the devil resurrected?
