The Villain System Starts Off, and I Go on a Killing Spree

What defines a villain? Is it a ruthless and invincible tyrant who doesn't care about family ties? Or a powerful and ruthless demon king who kills without hesitation? Reborn, Ye Wudao vows to become the strongest, most evil, and most brutal ultimate villain. The world calls me cruel and heartless, then I will be ruthless to the very end! People call me a demon, then I will be ten times more evil than any demon! If Heaven does not submit, destroy it. If all living beings do not submit, slaughter them! I am a great demon, and I will walk my own path alone! Anyone who dares to stand in my way will be killed, whether god or Buddha. Standing atop a mountain of corpses and a sea of ​​blood, Ye Wudao, knife in hand, looked down upon the masses with a cold, ruthless smile: "Those who submit to me prosper, those who defy me perish. I, Ye Wudao, am destined to be tyrannical and cruel in this life!" (System + sweeping victory + ruthless killing + no female lead + satisfying read + no saintly protagonist)
