In the 23rd year of the Republic of China, Feng Shui master Chen Qingshan went deep into the Black Ridge of western Hunan to search for the hanging coffin of the Black Bird Division and disappeared mysteriously. In order to find his grandfather's whereabouts, his grandson Chen Yanqiu, together with veteran Zhao Hu and ancient calligrapher Lin Wanqing, took half of the bronze token left by his grandfather into the dangerous and unpredictable Black Ridge forbidden area. Weird omens in Luoma Village, the resurrected corpses of the Black Bird Division, the hanging coffins on the cliffs, and the secret tomb mechanisms followed one after another. The three people supported each other in a desperate situation. They not only had to deal with strange evil spirits and deadly traps, but also faced third-party forces that coveted the tomb treasures. They gradually uncovered the truth about the collapse of the Black Bird Division and the secret of Chen Qingshan's disappearance, and finally faced the ultimate mystery behind the hanging coffins.
