In the autumn of 1979, a giant skeleton suspected to be a "real dragon" appeared in the hinterland of the Kunlun Mountains, breaking the tranquility of the geological exploration team. This is not only a subversion of biology, but also a shocking game about the destiny of the Chinese dragon vein. Bureau 749 intervened, where the secrets of Feng Shui and modern science collided fiercely. Bureau 749, a top-secret agency that really existed (or still exists), is responsible for investigating supernatural phenomena, special functions of the human body, and national secrets that cannot be explained by common sense. It has no name to the outside world, only a code name.
