Zhang Yang, who runs a grain depot, is burdened with enormous debts. By chance, he uses an ancestral bronze ding to open a space-time passage to ancient Great Ning. At that time, Great Ning is plagued by recurring droughts, its people are suffering, and foreign threats abound. Zhang Yang transports modern grain, farming tools, medicine, and other supplies to their aid, helping the local people survive famine and repel foreign enemies. Empress Qin Wanyun presents him with antique treasures in return, and the two gradually develop feelings for each other. When an accident causes the passage to become disconnected, Qin Wanyun rushes to his rescue. Bound by their mutual concern, the two promise to stay together and create a heartwarming love story.
