Apocalypse Reboot: I Become an Invincible Villain

In his previous life, he was the lord of Dragon City, one of the ten great cities of the apocalypse. But the dragon essence's beastly nature and a woman's betrayal made him an enemy of the world, ultimately leading to his death and the city's destruction!

Then the apocalypse restarted, sending everyone back to five minutes before the disaster with their memories intact. With a new dragon essence already fused with his body, he vowed to every survivor in the world that in this life, he would repay every pain and regret from his last one!

[Reason and madness + cold blood and passion + never a bleeding heart + decisive and ruthless]
