Technical backbone Xu Cheng'an led a team to build a robot model warehouse, but the promised 300,000 bonus was squeezed down to 6,000, and he was forced to sign a false handover form. Refusing to take the blame, he resolutely resigned after completing the handover. The new team rushed the acceptance, causing an 8,000,000 final payment to be withheld, and instead shifted the blame onto him. Facing defamation and material temptation, Xu Cheng'an used original records to expose forged sign-offs and procurement corruption, recovering his bonus and innocence. When the boss offered an annual salary of 1,200,000 to beg his return, he chose to start over as an independent consultant, guarding his professional baseline and returning time and promises to his family.
