Old Dreams of the Republic of China: the Covenant of Reincarnation

By chance, two history college students traveled to a parallel world during the Republic of China. At a time when the country was in crisis, they each served the motherland in their own way, trusting each other and supporting each other. After experiencing countless wars, they finally reunited with Su Ze and Shi Huaijin, sharing the love of a big country and the love of a small family. After decades and war-torn times, they thought they could stay together forever, but they were separated by yin and yang and made a promise in the next life.
