A jade Buddha weeps blood, and the alliance leader is found dead in a sealed room. The Grain Transport Gang is shaken by a sudden upheaval, and its Dragon Head is trapped in a web of intrigue. The wanderer Shen Yan has a strange constitution: when a Gu poison comes near him, he stiffens, and his blood merges with corpse worms. A cold-moon female constable conceals a broken kite in her sleeve as she investigates the truth behind a massacre. Together, they investigate a series of bizarre cases, from artisans offered as sacrifices to the stripping away of people's traits, while a sinister secret lies hidden in the Buddhist grotto. When a tower of bridal corpses reveals a map of the frontier, the cold-moon blood jade hairpin touches upon the truth. The golden marks on Shen Yan's arm awaken like a dragon, and an ancient Gu cry echoes from the depths of the underground palace! A fateful showdown is about to begin.
