A century-old distillery passed down through five generations faces a financial crisis. Lin Ye, its heir, is determined to preserve the traditional craft when he unexpectedly discovers that the giant vat in his cellar connects to a border fortress in another time and space. On the other side are soldiers defending the frontier, facing a desperate crisis of food shortages and injuries. Guided by kindness and a sense of responsibility, Lin Ye actively gathers supplies, continuously sending sorghum, sugar, medicine, and materials for logistics and infrastructure. Together, they overcome their desperate circumstances and rebuild their homeland. The rewards that come across time and space also help Lin Ye settle his real-world debts, putting his ancestral distillery on the path to revitalization as a modern industry.
