Shen Lang, a passionate young man who was born into a family of silkworm farmers, inherited the unique secret technique of cultivating the legendary "spiritual silkworms". At the beginning, the family business was suppressed by the "Yunjin League", a century-old chamber of commerce. The fiancée broke off the engagement and the family business was on the verge of bankruptcy. Relying on silk-raising technology that was far ahead of the times and the wisdom of "pretending to be a pig and eating a tiger", Shen Lang repeatedly made strange moves to survive. On the way to survive, he met Su Zhijin, a time-traveling woman and owner of an embroidery workshop who possesses modern knowledge. The two hit it off. Shen Lang used the peerless "spiritual silk" as the basis, and Su Zhijin used the subversive design and business philosophy as a tool to jointly create "the best silk in the world" and challenge the old business order. They launched thrilling business wars with the hypocritical and cunning chamber of commerce presidents and ambitious princes and nobles, from price wars, public opinion wars to supply chain competition, to court layout. In the end, Shen Lang not only established a huge silk empire, but also influenced the destiny of the country as a businessman and assisted the wise emperor when the country was in crisis, realizing the grand cause of "rejuvenating the country through business" and achieving a legend from a commoner boy to a business giant.
