Any murim recco as good as this?

Myst, might, mayhem is super good if your into true villain mc's who are op af and kinda unhinged. Its like if this mc chose the path of bloodshed instead of the good path, but without a time limit. They are similar in that they are both peerless martial artists, but that's where the similarities end. Myst's mc doesn't go around creating his own martial arts, but he has a perfect memory and masters any martial art pretty much the moment he sees/ reads it.
