End Times Star Crystals: I Have a Contract Beast Legion

[Ability Evolution · Selfish Protagonist · Reincarnation · Dark Humor · Early Development, Lone Wolf · Many Female Leads, avoid if you mind]

A meteor shower descends, the entire world collapses and is destroyed, and most people turn into terrifying monsters. Animals and plants are no longer resources for survivors, but become hunters instead.

Along with the meteor shower come star crystals, which can produce extraordinary food, weapons and equipment, evolution potions, ability bloodlines...

This is the apocalypse, a hell for most survivors!

But for evolvers and ability users, it is paradise...

Zhao Yin is reborn back to before the apocalypse and seizes his enemy's SSS-rank ability, Soul of Contract... In this life, he only wants to lead his companions to live better.
