In the first year of the Western Yuan Dynasty, Queen Yao Ying of Dali was assassinated, and her two children were stolen from each other: the prince Ruan Jinyu stayed in Luojing to survive, while the eldest princess Ruan Yushu, whose surname was Yin Shu, lived in the Yin Mansion of Qi Dynasty. The princes of the Qi Dynasty, Qi Mo and Yin Shu, became friends because of the magpie lantern in the clouds, and their youthful friendship grew secretly. Eight years later, Yao Ying built Yaowang Valley to find her relatives, and Yin Shu's life experience was revealed. Qixia Mountain underwent a bloody transformation, regained her identity as the eldest princess, and embarked on the road to revenge. In the past, Que Ying was separated due to the bloody sea of home and country. Qi Mo became Qi Dynasty and King Mo was deeply involved in a power struggle. Yushu followed her mother to plan for the restoration of the country. The two are enemies across mountains and rivers, and their youthful love is deep in their hearts. The magpie lantern in the clouds finally becomes the tenderest distant thought in the troubled times. In the chess game on the battlefield, they play out their involuntary love, hate and choices.
