Moon Mountain Mysteries tells the story of young archaeologist Cheng Lei, who is drawn into a crisis spanning heaven and earth and hundreds of years, thanks to his family's inherited Big Dipper birthmark and Seven Star Yin-Sealing Disc. The story begins with a paranormal incident at the Rare Selenium Hotel in a hot spring town in northern China. Cheng Lei discovers that the site is one of the nodes of the Seven Star Yin-Sealing Formation laid by Li Qian, a geomancer of the Ming Dynasty. As the investigation deepens, he joins forces with geologist Shen Qingwu and streamer Lin Xiaotang to oppose the mysterious organization Netherworld, which seeks to destroy the earth-vein network and awaken the "Source of Annihilation."
Following clues left by their ancestors, the three gather three key magical artifacts at the ice fields of Moon Mountain, the Qingqiu witch village, and the site of the Yin ruins, haunted by the baleful spirits of fallen soldiers. At last, they face off against Netherworld at the Eye of the South Sea's Guixu. Cheng Lei fuses the artifacts at the cost of his life, becoming a constellation that forever anchors the seal and protects the peace of the world. Blending folk legends, feng shui arts, and science-fiction imagination, the novel presents an epic adventure about protection and sacrifice.
