Su Qingyun, a descendant of tomb guardians, competes with an overseas tomb-raiding syndicate and independent folk feng shui masters for the Heavenly Book of Guicang inside a mysterious coffin. Drawing on the Guicang Yi, inherited from the Grand Diviner of the Shang Dynasty, and combining it with the Xiangxi Nuo shamanic tradition and the Guanzhong art of dragon seeking, the protagonist creates magical implements such as the Nine Luminaries Dragon-Locking Formation and the Blood-Soaked Bagua Mirror.
