Technical engineer Cheng Yuanzhou worked hard for three years with a monthly salary of only 3,800, relying on his mother for financial support. When he resigned, Chairman Song Qingman stopped him. As a result, the pay stub exposed the truth: his approved monthly salary was 38,000, but supervisor Zhao Hengxun withheld the difference, embezzling over 1.8 million in three years. After being suspended, Zhao Hengxun stole the project plan and defected to Jinhua, threatening the company. Entrusted with a critical task during a crisis, Cheng Yuanzhou completed the system upgrade in twelve days. Can he save the multi-million order?
