Modern supply chain practitioner Chen Mo travels through time to a fictional continent with empty pockets. Starting from improving pickled vegetables, he uses modern concepts such as direct sourcing, pre-storage, cross-regional grain dispatch, and people's workshops to break the hoarding monopoly of merchants like Wang Cai. After enduring rumors, supply disruptions, false accusations, disasters, and blockades by peers, he finally establishes a fair trade network that benefits all people and continues to expand into more distant regions.
