A cold surge hits the border between Xin and Cang Plains. Xin Plains Master sends Yin Zheng and Fourth Young Master for disaster relief as a test of their abilities. Fourth Young Master goes to the bigger town, Wuxiang, while Yin Zheng chooses to go to the more remote town, Canghe. The town is bitterly cold, and Yin Zheng physically researches and distributes relief supplies, but he neglects his own health and unfortunately catches a cold. Yet, he still holds on to help the local people solve their problems. (Source: Viu)
