Modern special agent Qin Feng unexpectedly transmigrates into a chaotic era of famine, becoming a down-and-out scholar with nothing to eat or wear. At the brink of despair, he awakens a daily bargain-hunting system. He ventures into the mountains to find a frozen deer and bravely fights a ferocious tiger to secure food. He saves Su Wanqing, Mu Yuner, and Li Ying, and together they struggle to survive in the turbulent times. By refining salt, making soap, and forging weapons, he gathers displaced refugees, destroys Black Wind Stronghold, and brings down a corrupt county deputy, gradually taking control of five commanderies. With bandits closing in and rival kingdoms embroiled in conflict, Qin Feng finances his military campaigns through trade, trains his troops, and expands his territory. Rising from a penniless scholar with absolutely nothing, he embarks on the path to becoming a supreme ruler who will conquer the world.
