Chosen One, how did I end up as the villain?

In a world where cultivation is a twisted and nightmarish pursuit, the boundaries between good and evil are blurred. A hundred-eyed deity asks, "Who is the chosen one?" The Buddha, a blazing sun on his back and golden lotuses beneath his feet, accuses with a ferocious grin, "That is a butcher! He has shed blood on countless people, slaughtered all the Buddhist monks of Wuliang Mountain, and nailed the twelve sorcerers of my Divine Witch Sect to the cross for strange birds to devour." The leader of the Divine Witch Sect is lifted up by mountains of corpses and seas of blood, while the barbarian king grits his teeth, "Even our Emperor was turned into a human pig by him!" Qin Huaiyu, a man with a cheat-like ability, transmigrates into this world, breaks through a deadly trap, and enters the realm of cultivation. With his wit and cunning, he outsmarts his foes, but will he be able to overcome the darkness within himself and find redemption in a world where demons are not demons, monsters are not monsters, and humans are not humans?
