Deep in the imperial city where imperial power and conspiracy are intertwined, the sound of banging at midnight tore through the thick fog and revealed an imperial secret that had been sealed for twenty years. Xuanyuan Ge, a mysterious young master lurking in the shadow of the imperial mausoleum, accidentally got involved in the series of puzzles involving the sudden death of the late emperor and the assassination of his father because of a piece of blood-stained jade.
The dragon pattern on the mutton-fat white jade is the remnant of the late emperor's Yunlong Pei, and it is also the key to the shocking truth. Mo Yuan, the secret guard under his command, has laid a dragnet, and the soft sound of the black iron wrist guard hitting the hilt of the sword involves the terrifying night of his father's assassination three years ago. When the red-glazed porcelain tiles from the royal kiln emerge from the cracks in the bricks, and when the screams of the night owls in the Imperial Ancestral Temple echo over the imperial city, Xuanyuan Ge must walk on the edge of the imperial power game and explore in the shadows: the truth behind the sudden death of the late emperor, the mastermind behind his father's assassination, and behind this piece of residual jade, the ultimate secret related to the fate of the dynasty.
This is a work that combines ancient-style machinations and suspenseful detective work. In the bizarre scenes of the imperial mausoleum, the Ancestral Temple, and the deep palace, Xuanyuan Ge will use his wits to break the situation, pursue the murderer with courage, and uncover the layers of fog shrouding the empire.
