Shen Yizhen, the sole heir to the Shen family's century-old legacy, was spending a fortune at an auction one second, and the next he received news of the family's bankruptcy. With his parents missing and creditors blocking the door, Mr. Shen, who used to be aloof and aloof, had to move into a village in the city and start a career as a 996 worker. However, on his first day of employment, he discovered that his direct boss was a sinister man in a black suit—this man was actually the director of the Underworld Office in Yangjian! Before Shen Yizhen could react, the "Underworld Infrastructure System" installation interface suddenly popped up on his phone: [It has been detected that the host has the bloodline of a top Feng Shui family and has been automatically bound. The main task: install an elevator for the eighteenth level of hell. The construction period is 365 days. If you fail, you will lose your soul. ] From then on, Shen Yizhen worked as a social worker in an office building during the day, and at night he transformed into the underworld engineering director, leading a bunch of monsters and ghosts to build infrastructure. Facing the ferocious King of Ghosts and the treacherous judge, he handed over the contract with an expressionless expression on his face: "Sign it, or I will report you for illegal construction." He turned around and hid in a corner, holding the tail of his fellow ghosts and muttering in a low voice: "It's so scary... You have to stick to it..." When the villains from all walks of life were gearing up to destroy this arrogant human being, they found that standing behind him was the entire underworld order that was on the verge of collapse.
