In late 1980s America, a boy named Louis awakens in a sinister manor where children are being experimented on by a cultish aristocratic family. As he navigates the terrifying rituals and psychological horrors surrounding him, he discovers a mysterious ancient Chinese text—the Left Way Folk Codex—that grants him access to forgotten, unorthodox occult arts rooted in folk superstition, corpse rituals, and taboo spiritual practices. With no allies but two other kidnapped children, Louis uses his sharp mind and the Codex’s esoteric techniques to survive, manipulate, and uncover the dark secrets of the manor.

As he begins to master side-path sorcery—using urine as a ward, cursing with filth, and binding spirits with borrowed death energy—he realizes these forbidden arts are not mere tricks, but the forgotten roots of divine power. The line between victim and predator blurs as Louis walks the Left Way, not to escape… but to ascend.
