A diagnosis of bone cancer caused Cheng Wanxing to accidentally travel through time and become an unpopular concubine in the prime minister's palace. She was forced to marry Pei Yan, the bloodthirsty King of Zhenbei. She was falsely accused of having an affair three days after her wedding. She saw through the conspiracy with modern wisdom, but she didn't know that this alleged marriage was a pawn in the struggle for royal power from the beginning.
At the palace banquet, she cleverly used the Western Regions Glazed Lamp to reveal the evidence that the prince had collaborated with the enemy and treason, but this triggered a mutiny in the Eastern Palace. In the shadow of the sword, Pei Yan protected her in his arms and said, "If you want to die, you have to get my consent," making two lonely hearts come closer quietly. As the relationship deepened, she discovered that the cinnabar mole at the end of Pei Yan's left eye hid a mystery. The cold poison that occurred every new moon was actually closely related to the royal secrets of the sudden death of the late emperor and the mysterious death of his mother and concubine twenty years ago.
At the same time, Cheng Mingshu, the sister-in-law of the Cheng Mansion, secretly colludes with the witch, and there is a secret technique that can control people's hearts hidden in the cellar; the dark red tattoo on the sleeves of Prince Li Chengzhao involves a larger conspiracy of rebellion. Cheng Wanxing used modern medical knowledge and ancient Gu magic to develop an antidote, but in the process he discovered that the truth about his time travel was inextricably linked to the ancient seal on Pei Yan and the lost royal treasure.
Machiavellianism and sincerity are intertwined, conspiracy and redemption coexist. In the turbulent court situation, Cheng Wanxing and Pei Yan work together to clear away the fog, and write a love-hate legend that spans time and space in the bloody storm.
