The daughter of a sinner who is proficient in medical skills marries the King of Zhenbei. From a contracted couple to a life and death partner, amidst the wars at the border and the undercurrent of the palace, they work together to uncover a bloody mystery that spans ten years.
"Xiao Yu, if the road ahead is a mountain of swords and a sea of fire, I will accompany you."
"Zhiyi, as long as you are here, this world is worth it."
This is not a traditional house fight, but a confrontation between medical skills and political intrigue; this is not a one-way rescue, but two lone stars illuminating each other; when the silver needle meets the sword, face the conspiracy head-on with kindness, and see how they fight their way out of this cannibalistic world, and keep the beautiful spring in their hearts.
"If your husband is the powerful King of Zhenbei, and you are his nominal princess - then you may have to know a little bit about everything."
