Zhou Xian, the young sect master of the Flaming Sword Sect, had a weak constitution and made slow progress after ten years of bitter cultivation, only to be backstabbed by his fiancée Liu Ruyan and her father, who crippled his dantian and discarded him. On the verge of death, he awakened the Heaven-Swallowing Body, capable of absorbing spiritual energy, analyzing techniques, and breaking through rapidly, reaching Foundation Establishment in just a few days. Fearing his growing strength, the Liu family colluded with outsiders to frame him as a demonic cultivator. Zhou Xian openly walked the Path of Heart Inquiry to prove his innocence. Facing suppression from a Sword Venerable at the half-step ascension realm, he devoured the origin of the Ruthless Sword Canon, comprehended the Great Dao of righteousness, broke through to the Deity Transformation realm, and used his own strength to wash away his stigma, proving that growth has no fixed formula and holding fast to one's original heart is the true Dao.
