Lin Qingyue, the chief medical examiner of modern times, once traveled through time and became the concubine of the Yongning Hou Mansion. She possesses modern forensic knowledge, toxicology and trace identification skills, and also hides the identity of a descendant of a remnant of the previous dynasty's bloodline - a saint from an ancient country in the Western Regions. Xiao Jingheng, the eldest son of Duke Zhenguo, looks weak and gentle on the surface, but is actually the commander of the "Xuanlin Guards" in charge of the Imperial City. However, he is poisoned by the "Nine Nether Heart Devouring" poison, which is incompatible with the heroine's bloodline.
Starting from the case of the floating corpse in the lotus pond of the Marquis Mansion, Lin Qingyue relied on his professional skills to peel off key evidence such as broken silver bracelets and lapis lazuli powder, and gradually became involved in disputes between various forces. In the process, key props such as the Pisces jade pendant, the black iron autopsy box, and the shark's silk veil also appeared one after another, connecting a series of cases and conspiracies.
As the plot progresses, she experiences the trap of marrying into the East Palace, deals with various forces in the palace, and solves strange cases such as the corpse case in the dry well in the cold palace and the plague mystery in the imperial kitchen. Later, he went to the Western Regions to explore the truth about the awakening of the saint and the destruction of the country, and encountered crises such as phantom poison mirages in the desert and prophecies from ancient city murals.
Since then, many tribulations such as the Twin Gu chaos, the Imperial City Division's conspiracy, the Yaowang Valley murderous plot, the shark man-made disaster in the East China Sea, the snow country's conspiracy in the northern Xinjiang, the changes in the Nine Layers Palace, the Red Flame Burning Heaven Tribulation, etc. Followed one after another. Faced with complicated situations such as the prince's substitute, the rebellion of the twelve earthly branches, the face-changing miracle doctor, the poison hidden in the pearl, and the emperor's seizure of the body, Lin Qingyue and Xiao Jingheng worked together to resolve the crisis again and again. Can they finally successfully prevent the restoration of the Western Region and the conspiracy to poison the Kyushu, and gain their own peace and happiness?
