In a world of immortal cultivation, the righteous and demonic paths stand opposed, while independent cultivators are treated like ants. Lu Chen was once an outer disciple of the Guiyuan Sect. After the demonic Blood Fiend Sect wiped out his sect, he narrowly escaped and obtained a mysterious bone talisman that can devour others’ spiritual power, cultivation techniques, and spiritual roots—but every use shortens his life. Hunted by the Blood Fiend Sect, met with indifference by the righteous path, and facing brutal competition in hidden realms, he must grow stronger at a frantic pace as his time runs out, struggling to survive between powerful factions.
