Down on his luck, young Lu Wei suffers a romantic setback and loses his job. By chance, he unlocks a time-travel passage hidden inside his family's ancestral wardrobe. Taking advantage of price differences between goods from two different eras, he starts a street-stall business and gradually builds his enterprise. Along the way, he fights foreign capital's attempts to block his progress and independently develops the rare-earth and semiconductor industries. When his special advantage stops working, he leads his team in pursuing independent research and development, expands into global markets, and achieves an extraordinary rise from humble beginnings, using industrial development to strengthen his country.
