Programmer Lin Yu died suddenly while working overtime and woke up as Qingxuanzong's handyman Lin Gou Sheng. Only the incomplete ancestral jade pendant was left in his arms, only to discover that the incomplete jade was the core of the ancient dimension shuttle experiment - it could purify substances, store data, warn of dangers, and even absorb evil energy and convert it into energy. In order to protect himself, Lin Yu turned on two vests: pretending to be a fool and acting stupid, using modern management to reduce dimensionality to combat the involution of immortality (PDCA wood cutting, KPI reform, equity incentives); darkening the mysterious weapon refiner of "Sacred Valley Ling" and shocking the black market with thread technology. He discovered that Zhang Huaian, the deacon of the outer sect, was actually a senior assistant who had traveled three hundred years and fell into the devil's path due to jealousy and distortion; while Zhao Xuanzhou, the law enforcement elder, had an unfathomable city and connived at the demon cultivators in order to catch bigger fish.
When Lin Yu teamed up with Su Qingyuan, an orphan from the country, and the mysterious shopkeeper Qian to investigate the truth, they were actually involved in a larger whirlpool - the depths of the eighteenth level of hell, where seventeen fragments of the residual jade were sealed. Each level has a gatekeeper; each level is a test of human nature. In the tongue-pulling hell, he saved thousands of monsters with tongues and heart-gnawing hearts; in the scissors hell, he endured the pain of cutting clothes for sinners; in the iron tree hell, he carried nine million iron thorns with his flesh and blood... An even more shocking truth emerged: Lord Yan was actually himself three thousand years later, and the gatekeepers of the eighteen levels of hell were all his clones in the previous life. And Su Qingyuan, pregnant with their child, was waiting in Qingxuan Sect.
Three thousand years of loneliness, the pain of ten thousand reincarnations, and the voice deep in my heart: Who are you?
