I Attain Emperorhood from the Start, Then Wipe Out My Entire Clan!

[Not a self-sacrificing saint + decisive and ruthless + one female lead + System granted in advance] I, Li Chu Yi, transmigrated into a fantasy world. I was born the son of an imperial clan, yet I was supposed to... complete other people? No. I’m going to live for myself. Three hundred years ago, they ripped out my Supreme Bone, shattered my mother’s heart meridian, and threw me into a mass grave to be eaten by dogs. Three hundred years later, I crawled out of a mountain of corpses and a sea of blood, and activated the [Darkening System]. [Choice One: Forgive them magnanimously. Reward: one sacred weapon] [Choice Two: Wipe out the entire Li family. Reward: The Black Heaven Emperor Scripture + the Coffin of Heavenly Burial (immortal weapon embryo)] I smiled. “I choose a third option.” “I want them... wiped out, down to the last chicken and dog!” That night, I attained the Dao and became an Emperor, taking the title [Fuyao]. That night, I tore apart the double-pupiled, killed my own father with a single blow, and swallowed the lingering souls of the Li family’s three ancestors. That night, I dug up the ancestral graves and scattered their ashes. I didn’t spare even the five-year-old children. The court historians call me cruel? To hell with history! I’ll write my own! I recruited nine great heavenly generals and bestowed on them the Black Heaven Demon Scripture. Those nine mad dogs went after their debts, striking terror throughout the heavens. I fought the Supreme Ones of the forbidden zones, lived a second and third life, and forced the Celestial Venerables of myth to burn through every last drop of their power before calling a truce. I have a Heaven-Devouring Bone that can consume all Daos. I have a Severing Immortality Sword that can cut down every injustice in the world. I have the Human Emperor Banner. Need a few main souls? As it happens, there are plenty of old monsters in the forbidden zones. In this life, I won’t be a saint, a dutiful son, or a coward who swallows every humiliation. I’ll be... the Darkened Heavenly Emperor! “The suffering of the mortal world can be answered by only one sword from me, Li Chu Yi. It can move mountains, sever rivers, overturn seas, subdue demons, suppress devils, command gods, pluck stars, destroy cities, and split open the heavens!” “Bring me my sword!”
