[Suspense + Supernatural + Secret Technique + Tomb Robbery]] There has been heavy rain in the southwest mountains for months, and a strange "borrowed bone burial" has revealed its clues in the landslide. Qin Zheng, a folk caveman, was forced to step into the place of living burial that he least wanted to touch because his master Shen Laizi died outside the tomb and half of the mysterious Sinan appeared in the world. As he goes deep into the mountains, cracks down on mechanisms, and traces the truth behind his father Qin Beidou's disappearance, he gradually discovers that the so-called ancient tombs do not exist in isolation, but some kind of huge underground network covering mountains, rivers, and dragons.
A network called the "Sky Coffin" involves Jiu Mojin Vein, Feng Shui Masters, descendants of Qianjiying, Jiuju Remnant Veins, Lingnan Five Poison Sect, archaeologists and overseas consortiums. Every tomb, every door, every hanging coffin, and every deep well is not only a place to bury the dead, but also a node for suppression, borrowing, sealing, and transportation. Every time Qin Zheng opens a tomb door, he will get closer to the deeper truth, and greater disasters will awaken from the darkness.
From "Borrowed Bone Burial" to "Black Lantern Gorge", from "Sea Eye Coffin" to "Snow Mountain Bone City", and finally to the core area of "Sky Coffin", the story will gradually unfold a huge adventure spanning hundreds of years, involving earth veins, dynasty secrets, ancient engineering, the mystery of immortality and human greed.
