Artist Shen Muzhen, burdened with a huge contract termination debt of 200 million, relies on a bowl of white porridge to exchange a mysterious glowing food truck of a hundred years for top-grade jade. This food truck connects to an ancient famine-stricken mountain and becomes her trump card to pay off the astronomical penalty. She transports refined salt and compressed biscuits to the other world, and saves dying soldiers with modern antibiotics. On the modern side, with the huge sum obtained from cross-time-and-space transactions, she publicly shatters her former manager's blockade scheme; on the ancient side, with material dimensionality-reduction support, she builds the desperate exiled army into an iron cavalry that sweeps the world. The order of the two worlds is intertwined because of the food truck; Shen Muzhen shuttles through dual-line transactions, building her own unique business empire.
