In an imaginary world of chaos, dust is everywhere, the northern cavalry breaks through the wind and sand, and the undercurrent in the court is surging. A young man who was born as a general joined the army and guarded the frontier when he was still young. With his iron-blooded pride, he went through various battles such as the Battle of Yanmen Pass and the counterinsurgency in the Hexi Corridor. He was tempered and grown up in the shadow of swords and swords, vowing to protect the safety of the mountains and rivers and the peace of the people. The medical woman who cares about the common people travels through borders in troubled times, treating the wounded with golden needles and jade dew, and adhering to the benevolence of a doctor.
An encounter on the battlefield closely linked the fates of the iron-blooded general and the gentle medical woman. When there was an emergency at the border, he charged with blood, and she was at the rear collecting medicinal materials and treating wounded soldiers; when the court fell into trouble, she resolved the crisis with wisdom, and he dispelled the rumors with loyalty. Their love does not have the lingering love before flowers and under the moon, but only the concern of the beacon fire in March and the sincerity of Yan Shu's love.
In the troubled times that merged with the real historical context, the two worked hand in hand to write the righteousness of their family and country on the iron-blooded battlefield, and stick to their original aspirations amidst the ups and downs. From guarding the border to quelling civil strife, from court games to the stability of people's livelihood, they used their lives and blood to interpret the promise of "holding the son's hand and growing old together with him", witnessing the magnificent journey of a dynasty from division to reunification, and leaving a legend of iron blood and tenderness intertwined in the long river of history.
