A betrayal in a laboratory unleashed a deadly red mist that devoured an entire city and left researcher Ling Feng on the brink of death. At the edge of life and death, he fell into a bizarre, high-martial-arts dreamscape built from the red mist. Bearing the supernatural abilities of "Space" and "Devour," he struggles to survive on the path through the Nine Realms, yet whenever he teeters on the brink of death, the mysterious woman Lu Qingyi saves him. She carries the scent of gardenias, like the only light in his despair. The Poison Dragon Gang's thugs and the Scavengers' relentless pursuit close in at every turn, reflecting the cold malice of the mastermind behind the scenes in reality. As Ling Feng tears through layers of conspiracy and draws closer to the truth, a horrifying fact comes to light: this world of the Nine Realms is nothing but a hallucination born of his dying mind, Lu Qingyi is a split personality bearing the agony that gnaws at him, and the "Heavenly Dao," which watches everything with indifference, is none other than the Grim Reaper closing in on him in reality! At the end of the red-mist-shrouded road, he must crush the thugs and confront the mastermind. More than that, in this illusory dream, he must wield his final sword as his "true self," striking back at merciless fate, for redemption, for the struggle, and for that wisp of gardenia fragrance that burns through the abyss.
