Ling Jueying, the empire's top agent, died in the line of duty. When she opened her eyes, she traveled through time and became the third daughter of the Ling family of Yungang Kingdom - the foolish legitimate daughter who was thrown into a deep well by her stepmother Liu Yuru and was stigmatized as a "collaborator and treason".
In a desperate situation at the beginning, she relied on her secret agent instincts to break out of the situation and escape, but she bumped into the reborn Seventh Prince Ye Chenyuan. He was the God of War who was betrayed by "her" in his previous life and lost a hundred thousand soldiers. He had a lot of hatred in his eyes, but he always blocked her murderous attempts in the dark. She used modern medical skills and fighting skills to uncover the collusion conspiracy between Liu Yuru and the second prince, while exploring the truth about the original owner's "betrayal".
The lavender peach blossom sachet hides the tenderness of the previous life's engagement. The secret letter from Mobei Old Station reveals the conspiracy of tampering. She gradually discovers that the "betrayal" of the original owner was actually the fault of the second prince. Ye Chenyuan went from resentment to complete trust, from indifferent spectators to sacrificing his life to protect each other; Ling Jueying also went from fighting alone to working side by side with him - the intrigues in the court were undercurrent, and the birthday banquet was full of murderous intentions. The two of them worked together to break the poisonous scheme, fight against the party, protect the prince, and protect the country.
When the reborn war god sheds his hatred, and when the time-traveling medical concubine releases the shackles of fate, the misunderstandings in the past life finally become the fetters of this life. In the precarious dynasty, they create a legend of "the shadow protects the tomb, the medical concubine stabilizes the country" in the turbulent dynasty.
