The Dragon Bone Mystery of the Sapphire Case

Late at night, Zhong Dingwen, the former director of the Museum's Epigraphy Department, was killed at home. The corpse was placed in the posture of the Warring States period silk painting "Characters Controlling the Dragon" - facing up to the sky, with arms spread out like a dragon ascending to the sky, with eight words written in cinnabar on the chest: "The dragon hides in the abyss, the jade breaks in the tripod." A broken jade cong from the Warring States Period was scattered around him. The cong was engraved with a line of unidentifiable oracle bone inscriptions.
