The Great Demon King of Condor Heroes

Transmigrated into a comprehensive martial world, becoming a demon in one fell swoop, overwhelming the three realms. After overthrowing the Black Abyss Lord and quelling the invasion from another world, I could have rested and recuperated. Unexpectedly, the Abyss Realm fell into internal strife, with three demon marshals carving up territories and colluding with the Blood Fiend and Bone Spirit realms to breach the Ten Thousand Realm Demon Array and covet the three realms. Urgent reports from demon spies signal the resurgence of war. I made critical decisions in the crisis, sending spies, setting up killing arrays, and preparing the army, stirring up the heavens with my own strength. Since you seek death, I will dye the abyss with blood, making all realms know: when the Demon Lord is enraged, billions fall!
