My Entire Clan Was Slaughtered, So I Abandoned the Sea of Realms and Unleashed a Dark Calamity

[Only one Great Emperor in the current era; Great Emperor from the start; returns in three chapters; invincible; no System; exterminates his clan] “The suffering of these creatures is exactly what their understanding deserves!” Jiang Feiyi suppressed the Great Dao for a full million years! No one could attain the Dao and become an emperor! Nine Quasi-Emperors turned their weapons against the Jiang family, an ancient imperial clan. As its members died one after another, Jiang Feiyi, who had guarded the Starry Sea of Realms for a million years, became entangled in a strange “resentment” and turned his back on his post! “Creatures of the tainted lands, you may enter!” “Trash from the forbidden zones of life, our pact is void. The world is in chaos now, so why aren’t you rising up?!” “They’ve had it too good. This dark upheaval is what they deserve!!!” Only belatedly did the ungrateful lot realize the truth. They begged for mercy: “Heavenly Emperor, we know we were wrong. The law does not punish the many. Surely you won’t kill every living being across the three thousand universes? We beg you to spare our lives so we can atone!” “Hah. You don’t know you were wrong. You know you’re about to die!” The Imperial Princes and Princesses saw their Dao hearts shatter and cried out in despair: “Heavenly Emperor! Aren’t you afraid of earning a terrible reputation and corrupting your heart with demonic influence?!” Cold lightning flashed in Jiang Feiyi’s eyes as his white robes transformed into an abyssal black: “Why not?”
