The story takes place in the "purification layer" of the spiral of disaster. The protagonist Fan Sheng is a 98-year-old swordsman who is burdened with the "Yuetong Curse" due to the backlash of his early vows. Every full moon, he returns to his old age and regains his youth, temporarily losing his cultivation. He lived in seclusion in the city, made a living by carving "memory puppets", practiced "The Web Sutra of Destiny", and tried to weave the cause and effect of his own brokenness. Due to a rescue, he got involved in the "Climbing the Spiral" movement launched by the "dirty people" at the bottom to fight for the upward path, and got acquainted with its leader - Mo Lin, an orphan with the bloodline of the "Nine Nether Mysterious Kirin". At the same time, the chief judge of the "Eternal Temple" regarded all unorthodox practices as heresy and began a campaign of suppression. Fan Sheng swayed between protection and escape. When the moon was full as a child, he accidentally touched the forgotten root of the "Tree of Memory" and got a glimpse of the truth about the reincarnation of the world. He gradually realized that the true "enlightenment" is not to climb to the top of the spiral, but to weave good relationships and reconcile conflicts in the fireworks of life. In the end, he used the "Eternal Moment Sword" to cut off the causal line of his own curse, but chose to use his power to heal the class rifts, open up a "natural dojo" in the new layer, teach the method of "life is practice" in the "Xuanhuang Creation Alchemy Record", and become a bridge connecting all levels.
