Lu Yang, a roadside construction worker, unexpectedly acquires a strange tablet computer, which is then recognized as his master. From then on, he frequently receives bizarre missions from this strange computer, and is even thrown into extremely dangerous ghost realms. Successfully completing these strange missions earns him "Ghost Points," which can be exchanged for anything he desires, such as strength, intelligence, health, handsomeness, money, and beautiful women. Besides Ghost Points, the computer also contains various ghost cards, such as invisibility cards, healing cards, and name-removal cards… From then on, the life of the humble construction worker becomes anything but ordinary.
