Heaven's Secret 2: The Abyss of Dian

Lu Mingyuan (Aye), a twenty-eight-year-old low-level hustler, is drawn into a civilization-spanning conflict spanning 42,000 years by a mysterious jade token left by his father. His father, Lu Chen, disappeared three years ago at the Kunlun Mountain node, leaving only a cryptic message: "Go to southern Yunnan, find the book beneath the water." As Aye investigates, he uncovers the existence of three major families—the Lu, Duan, and Ailao clans—who have guarded three core nodes left by the ancestors (the Sowers): the Book of Perception, the Book of Rewriting, and the Book of Creation. His father, it turns out, discovered the "Fourth Power" that bridges them. With the help of the aloof Duan family head, Duan Qingyi; the mysterious Ailao priest, Elder Tianshu; and Victor, a guardian created from his father's consciousness, Aye gradually awakens his source core and becomes the "Bridge" between humanity and the ancestors. — Description from novelcodex.org
