Lu Ze partnered with Tang Yao to operate an agricultural machinery fleet, contributing his technical expertise as his investment. With his exceptional skills, he revived a fleet on the verge of bankruptcy and secured a major 30-million-yuan contract to harvest wheat fields before the deadline. However, Tang Yao became greedy, withholding tens of millions of yuan in profit shares before ruthlessly firing him. At the same time, Lu Ze's daughter suddenly fell seriously ill, requiring an enormous amount of money for medical treatment. When Lu Ze sought help, he was met with nothing but endless obstacles and humiliation. After Tang Yao's improper operation caused three precision agricultural machines to break down, he faced an approaching torrential rainstorm and massive compensation claims, leaving him no choice but to swallow his pride and beg Lu Ze for help. Lu Ze recovers his rightful share of the profits, repairs the machines, completes the harvest in time, and eventually establishes his own business.
