An entomologist’s soul transmigrates into a cultivation world, inhabiting the body of a small, obscure cultivator who specializes in insect manipulation. Reborn, he desires only to avoid conflict and quietly develop in a mortal village.Inspired by the “Sun-Moon Heart Sutra,” he creates his own “Ten Absolute Scripture.” Inspired by the “Nine Deaths Divine Art,” he devises the “Purgatory True Demon Technique.” Moved by the “Eternal Life Sutra.” he extrapolates it into a hundred layers.With boundless creativity, extraordinary insight, and unlimited time, he pioneers new techniques, pill formulas, artifact designs, array formations, gu recipes, poison concoctions, and brewing methods—all entirely of his own invention.While others cultivate paths of slaughter, he alone forges and cultivates the path of self creation.
