Chu Yu, the daughter of the general, returned to the capital to rescue her lover Gu Chusheng, who was implicated in the rebellion of King Qin. Unexpectedly, he killed Chu Yu for Zhao Yue. Wei Yun, the seventh son of the Zhenguo Marquis, accidentally rescued the dying Chu Yu. Facing the emperor's pressure, in order to protect Chu Yu's reputation, Wei Jun, the eldest son of Wei, came forward to marry Chu Yu and resolve the crisis. On the night of the wedding, Wei Jun presented the letter of separation and Chu Yu regained his freedom. Beidi invaded the Wei family and went on an expedition. The prince and his uncle Yao Yong were greedy for power and ordered 70,000 loyal souls of the Wei family to be buried in Baidi Valley, leaving Wei Yun alone. The two even went to the police to accuse the Wei family of rashly advancing and leading to their defeat. Wei Yun returned to Beijing and was arrested. Chu Yu returned to the Wei family and used her identity as the eldest sister-in-law to do things around in exchange for Wei Yun's life. From then on, the two vowed to find out the truth and revive the Wei family. Chu Yu and Wei Yun successfully resisted Beidi after a narrow escape and defended Fengling City and Tianshou Pass. The two also gradually got closer in the ordeal, but a decree and reward destined them to never meet in this life. Zhao Yue colluded with Beidi and hijacked the young emperor to seek the throne. Wei and Chu also discovered that the real murderer in Baidi Valley was Zhao Yue. They fought bravely and finally killed Zhao Yue to clear their grievances. For the sake of the safety of their family and country, the two blew up the secret road in the snow-capped mountains. From then on, the mountains and rivers became a pillow between heaven and earth.
