Shen Pingsheng is born with a death vein, and fails every attempt to awaken his spirit. Cast aside by his sect, he is exiled to a mine in the deadly Southern Wilds, where he becomes a slave at the mercy of others. Amid endless darkness and the brink of death, an ancient stone tomb sealed away for countless ages awakens deep within his sea of consciousness. Its eerie demonic power rewrites his ruined meridians, setting him on a mad path of devouring Yin marrow and cultivating against the Dao. He learns that the Heavenly Dao shackles all cultivators, while the upper realm's Spirit Ruins use all living beings as provisions and reincarnation as a harvesting tool, manipulating the world's false order. With nowhere left to turn, Shen Pingsheng enters the Underworld in the flesh, uncovers the secrets of the eras, and discovers that he is the fated variable destined to oppose the Spirit Ruins.
From then on, he abandons ascension, shatters the Heavenly Dao, and defies the cosmos. With karmic fire, he burns away illusion, overturns a thousand-year-old order by his own strength, and breaks the prison of a world built by the Spirit Ruins. This so-called mad demon seeks not to destroy the world, but to escape fate and set all living beings free. At last, the old Heavenly Dao collapses and its shackles shatter, while Shen Pingsheng proves the Dao with his own body.
