Don't Panic, Protagonist, I'm Here to Bring You a Cheat

(The protagonist is invincible. His main job is handing out cheat abilities and thrashing villains, with the occasional side gig as the protagonist.)

There are plenty of stories in this book, so there's bound to be one you'll like!

Reborn as a god, Fang Nan starts out at a height no other transmigrator can reach.

While everyone else waits for the System to show up, he creates one himself...

The protagonist is too weak? “Want a sign-in System?”

What? The villain is reborn and has a System too? That won't do. “Do you know the true worth of a life-for-power System?”

You say you've got a grudge against the villain? Easy. Here's a Beast-Taming System. Go make his life difficult.

Fang Nan travels through the Myriad Worlds, going further and further down the road of handing out cheat abilities.

The first world is an apocalypse, and its theme is sheer cruelty. I'd call it a chronicle of the villain's struggle. (A chaotic System free-for-all.)

The second world is a world of magic. The protagonist is the Demon King, and he steamrolls heroes of every kind.
