Lin Shi, a young man who believes in lying flat, transmigrates to the Primordial World and becomes the Heavenly Dao's only temporary worker. During the Dao-Demon War, he cheers from the sidelines; during the Dragon-Phoenix Tribulation, he cleans up the battlefield. He sticks to the workplace rules of “pick no sides, accept no responsibility, and leave as soon as the job is done,” struggling to survive among the Primordial World's powerhouses.
When a bloodthirsty Great Shaman demands he take a side, he calmly produces the Heavenly Dao Employment Agreement. When the Demon Ancestor Luo Hou blows himself up, Lin Shi immediately calculates the depreciation on the Immortal-Slaying Sword Formation. All he wants is to earn enough work points to become a permanent employee and secure a steady job. But when Dao Ancestor Hongjun lays the “ultimate resignation paperwork” for merging with the Dao in front of him, Lin Shi realizes this job might “optimize” him straight into becoming part of the Heavenly Dao!
