I'm so Unlucky That the Underworld Made Me the King of Scrolls

Drinking cold water to stuff his teeth, falling off a manhole cover while walking, Lin Xiaofan used his life to explain what "causal-level" misfortune is. It wasn't until he died of poisoning from a half-can of beer that a rat had licked that he realized that his longevity was all due to the crazy "connection" of his eighteenth generation ancestor who served in the underworld. In the Hall of the King of Hell, the King of Hell was stunned: "Lin Xiaofan, your Yang life has expired, but because of your loyalty and diligence from generation to generation, the Lin family has specially allowed you to return to Yang and be included in the "special talent establishment in the Yang world" of the underworld!" As a result, Lin Xiaofan's rebirth turned into a frantic pursuit of KPIs from the underworld: Helping Niutou Mamian catch resentful souls, developing new soups for Po Meng, and optimizing the life and death book system for the judge... The rewards are very generous: clairvoyant treasure appraisal, golden eye, soul-soothing bell, all of which are cheating skills. But the conditions of use... Are more shameful than the last! Kneel down on one knee and shout "Onii-chan, follow me", fart at the incense burner, and practice by relying on apes to explore the sea and electrocute seaweed dance... When Lin Xiaofan relied on his weird skills to counterattack and become a god in the underworld, he discovered that behind the underworld's "weapon", there was a shocking conspiracy that swept through the yin and yang... Let's see how the unluckiest candidate in history "examines" an invincible student within the underworld system!
