Traditional cultivation of immortality requires spiritual roots, spiritual energy, and techniques. In the world where the protagonist lives, the aura is being polluted by a slowly spreading and irreversible "bone-eroding nether energy". Once the contaminated spiritual energy is inhaled, it will corrode the Taoist foundation, corrupt the body, distort the soul, and eventually turn the monk into a "eclipse demon" who only knows destruction. The orthodox path to immortality has almost been cut off. The protagonist accidentally discovers a piece of jade that can directly swallow and digest the "bone-eroding ghost energy" and transform it into a unique and more domineering "eclipse element" for cultivation. He is the beginning of "eclipse repair".
