Xu Mo worked at a factory for seven years as a handyman whose only job was supposedly fixing printers. He was casually insulted and had his pay docked by the director before being publicly fired by the chairman. But when HR checked the system, there was no record of him! As it turned out, he was a top on-site expert dispatched by the Sihai Group, earning an annual salary of three million. He could repair million-dollar E7 equipment in just three seconds. Tianqi had exploited him as free labor for seven years. When the equipment finally shut down, the entire company ground to a halt. They offered millions to beg him to return, but he gave them just one reply: "I'm not here to fix your machines. I'm a technical expert." In the end, Tianqi went bankrupt and was acquired, while Xu Mo became the general manager of the new base.
