The female widower traces the truth about the family injustice in the corpse case and the mystery of the ancient tomb, and gradually uncovers a larger conspiracy. The Shen family, the number one treasure appraiser in the capital, was brutally wiped out. The legitimate daughter Shen Qingwu was reduced to a low-level widower, making a living by examining corpses and secretly seeking revenge. The dragon scale pattern on a floating corpse accidentally involved her in the secret talisman in her father's relics. She was even coerced by the mysterious man Lu Jiuzhang to go deep into the ancient tombs of Mobei to find the dragon scale coffin. The tomb is densely covered with traps and murderous intent. Shen Qingwu uses his autopsy skills to solve the problem and discovers the bones of his missing brother and family tokens in the coffin. All clues point to the murder of the Shen family not as an unjust case, but as a shocking conspiracy involving the secret treasures of the previous dynasty and the secrets of the royal family. Xiao Yi, wearing a mysterious mask, came to the rescue several times, but his identity remained a mystery. The birthmark on his body and the mark of the Black Bird Guard were actually closely related to the bloodline of the Shen family. As the blood jade, star map, and secret scrolls emerge one by one, Shen Qingwu is shocked to realize that what the Shen family has guarded for generations is not the treasure, but the secret of the dragon vein and the mystery of the twin bloodlines that can overturn the government; Xiao Yi's identity, the cause of his brother's death, his father's injustice, and Lu Jiuyuan's conspiracy all revolve around the Shen family's secret technique of "listening to bones for treasures" and a dragon-scale jade pendant. Using bones as the key and blood as the guide, she breaks through the ancient tombs, underground palaces, and imperial cities step by step, uncovering the truth about the twins' bones, the secret history of the Black Bird Guards, and the royal family's parricide and power seizure.
