After spending twenty years in another world, Su Yuanxiu is selected by a horror game. At the moment of teleportation, he unexpectedly binds himself to a Home Lord System and gains the SSS-rank talent—Bones Buried in the Grave. He arrives at a dilapidated skeleton territory and, with the help of his strategist A Suan and skeleton soldiers Xiao Zhang and Xiao Wang, travels through terrifying game instances to repay his yin-energy debts. He scavenges yin energy aboard a bus of the dead, captures ghosts to serve as “biological batteries” in the Night Watchman instance, and joins forces with a vampire lady in an ancient forest castle to kill a Corpse Ghoul Lord. From being deeply in debt to awakening the evil spirit warhorse Red Shadow, Su Yuanxiu gradually expands his territory through his unique “scavenging for junk” survival strategy.
