Lingjian Sect's junior sister Jiang Wan was born with severed meridians and completely lacking spiritual roots. For three years, she has been sickly and weak, unable to even reach the first layer of Qi refinement, and is treated by the entire sect as a useless sickly person. But no one knows that her true form is actually the sword soul of the ancient Guixu Divine Sword, only fallen into slumber and residing within a mortal shell. After being locked in the Sword Tomb, all swords surrender to her; when the demon race invades, she snaps a withered branch and sweeps flat ten thousand demon armies. From then on, her master gives her his private treasury, her senior brothers protect her with all their might, the magic sword acknowledges her as master, and abandoned swords revive upon seeing her. As piece by piece of the sword scales return to their place, her memories slowly awaken.
