Su Xuan, a psychiatrist in his previous life, traveled to a fantasy world and had his body drained of its origins, and was about to be sacrificed.
At the critical moment of life and death, the [Fate Rewriting System] is activated and the first template is unlocked: Death God Xu Bai.
He soon discovered that the rulers of this continent, the Nine Holy Dynasties, were all predators who maintained their rule by devouring the luck of geniuses. And he was just one of the countless sacrifices "raised" by the Holy Emperor.
When the prince of the Holy Dynasty wanted to make him into a puppet, Su Xuan laughed.
[Hokage Template·Sharingan], [One Piece Template·Overlord Color Haki]... The templates of all realms are coming one after another.
With one person's power, he leveraged the ten thousand-year foundation of the nine holy dynasties. Since this world wants to force him to become a demon, then he, Su Xuan, will become the Demon Emperor of all heavens and realms!
