Apocalypse: I Began to Ascend to Godhood After Sacrificing My Humanity

Nontraditional apocalypse, plot-driven, invincible protagonist, true antagonist, weak System, multiple female leads (?), dark, ensemble cast

A gray rain falls across the world. Living things that touch the water begin to turn to stone, and the old order rapidly crumbles amid hunger and fear.

At his most desperate, Li Rong obtains a System that demands his mental strength as payment. Fear, pain, despair... The emotions of all living beings can nourish his power.

While the survivors fight each other over a single bite of food, Li Rong is already studying their desires, creating his own apostles, and attempting to establish new rules.

He simply hasn't realized yet that power never comes from nothing.

The gods are fair.

As people sacrifice their desires in exchange for abilities, Li Rong is sacrificing himself, too.

And when humanity has vanished completely, what will remain: a perfect god, or a monster that can never be satisfied?
