In a world where turning eighteen mandates entry into the Lord World or face a fatal curse, Lu Cang faces imminent death. As a transmigrator, his awakening of an 'evil-type' territory gets him blacklisted by the authorities, leaving him to rot while others proceed. Desperate and running out of time, he joins the underground Curse Society to smuggle himself into the game through a forbidden corridor.

Upon arrival, his transmigration status triggers a hidden upgrade, transforming his lowly Hero-rank seed into a Supreme-rank 'Source Flesh and Blood Mother Nest.' Now protected by a seven-day invincibility shield, Lu Cang establishes his domain atop a rare Secret Steel Stone Mountain in a monster-infested rainforest. While the establishment hunts down those who helped him, Lu Cang begins his journey of infinite evolution, commanding a terrifying hive of flesh and blood to survive and dominate a realm where only the strong devour the weak.
