Lou Yi arrives in this complex world, becoming a penniless and helpless woodcutter. One day, he and his fellow woodcutters are attacked by a tiger when working and one of his friend gets killed. Lou Yi manages to pull himself together and wants to carry his friend's body home. The moment he touches the body, a line of semi-transparent text appears suddenly before his eyes: "Energy +1, absorb it?"

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.

People know that ghosts are terrifying, but ghosts understand the malice in human hearts. This is a traditional supernatural novel.
