Chen Yue, a high school dropout, was expelled for offending his boss. He had no choice but to work as a cleaner in a technology company. While mopping the floor, he wrote down the business logic on the whiteboard in the conference room, and used his spare time to teach himself Excel and data analysis. Fang Xu, the airborne vice president, discovered that this cleaner could sort out the loopholes in the department's process within ten minutes, and transferred him to the project team as an exception. In half a year, Chen Yue went from being a downtrodden cleaner to acting director, and by the way, he sent Zhao Ming, the veteran of the company who was secretly hollowing out the company, into the police. But Fang Xu's real enemy is still in the dark - once the USB flash drive in Chen Yue's hand is made public, it will blow up half the industry.
