I'm Really Into Invincible, Ruthless Protagonists Lately. They Have to Be Invincible from Start to Finish, Not Just for a While

Looking for books similar to Already Invincible, So Why Bother Cultivating? (Immortal Emperor Can Annihilate You with a Flick of His Finger). I want someone who is completely invincible, knows they're invincible, doesn't hide it, and is decisive and ruthless, not a do-gooder. Don't recommend stories where the protagonist gradually becomes invincible. I want the real deal: mess with me and I'll wipe out your whole family.
