On a stormy night, delivery worker Lin Chen is publicly dumped by his girlfriend and his dignity is crushed, but a single kind deed leads him to save business tycoon Gu Zhenshan, changing his life forever. Relying on his memory of community delivery routes covering the whole city and his grassroots empathy, he starts from selling vegetables in the community, successively securing supermarket supply deals and capturing a commercial complex, making a counter-attack to become the leading fresh produce supply chain tycoon, and ultimately marrying the benefactor's granddaughter, slapping the faces of everyone who looked down on him.
