[Urban power fantasy + harem + game descends into reality + apocalypse + traits + travel between two worlds]
Bai Hao's life hits rock bottom: framed by his ex-wife, disgraced, and thrown out with nothing.
An accident connects him to the mysterious game The Apocalypse. Killing monsters can actually drop real traits, which let him enhance his strength, speed, and even gain superpowers!
Everything changes when he discovers that traits from the game can be brought back to reality, and can even cure terminal illnesses in the real world.
To save his mother, who has cancer, he has no choice but to venture deep into that despairing world overrun by Cthulhu monsters.
But stronger traits mean more terrifying enemies. And the troubles of the real world are far from over...
This is a wild adventure spanning two worlds, where traits are his blade and he fights for life.
You make your own settings, and the rest is fine
