Zhang Tao, a modern grain administrator, transmigrates to China's most turbulent ancient era: the Five Dynasties period. Using his golden finger, a grain-storage technique that prevents insect damage, he saves a local small-time grain merchant's warehouse of moldy grain, seizes the chance to buy low and sell high as the Jin and Liang armies clash and grain prices soar, befriends low-ranking military leaders and minor officials to build an information network, and helps Li Cunxu's army resolve a crisis caused by moldy military provisions, gaining access to the upper echelons of Later Tang... Step by step, he rises to dominate the chaotic age.
