Overpowered Protagonist

Looking for some novels with Op Protagonists.

Either Op from start or becoming op real fast.

By Op mc, I mean Overpowered in all Aspects rather than a Single ability.

Like better than everyone and pretty much everything.

I don't mind weak to strong but it's fine as long as Mc have extremely overpowered cheat that no one could match him. Like Leveling hundreds of Levels in a single volume. Something like that. Op class or so.
