Amidst a world plunged into chaos, where rituals have collapsed and music has spoiled, and the universe is muddled, Gu Qingfeng finds himself transported to this tumultuous era. Initially, he only desired to live out his remaining years in peace. However, the birth of his first son made him realize that things were not as simple as he had imagined...
Apocalypse befell, and roommates performed a skyward ritual. As the fog descended, the Book of Blood Spirit appeared in the hands of all survivors, and only those with a Contract monster could survive. Su Han directed his gaze to the neighbor who had already mutated and twisted, silently pulling out a gleaming fruit knife... Grotesque meat corpses, giant spiders with gaping mouths, eyeballs enveloping the city, one-eyed sharp-toothed hand monsters... Civilization fell, cities shattered, and all humans became meat for the monsters. There was only one way to survive: Use monsters to fight monsters.
