In the "Xuanhuang Realm", it is the end of a cultivation civilization where the cultural context is declining and the tools are prevalent. The protagonist, Yu Zhizhi, is sixty-five years old. He is an old Confucian scholar who has studied ancient books all his life but failed to find the right method. When he was sorting out the broken slips passed down from his ancestors, he accidentally touched the fragments of the "Record of Cultural Heritage" and "enlightened" a broken jade slip named "Shen Yan" in a mortal body, and was forced to embark on the path of cultivating immortality. In the process of training, he met Yan Ling'er, a girl who was convicted of a crime and was turned into a "living puppet", and the mysterious monk Observer from a higher civilization. Faced with the shackles of thinking imposed by the "language cage", the questioning of the past by the "incarnation of choice", and the coveting of inheritance by "traditional contenders", Yu Zhizhi gradually became involved in a "contextual war" that spanned civilization levels. He must use what he has learned throughout his life to reinterpret Taoism in the dilemma of "unspeakable words" and fight against powerful enemies that can trigger the forbidden magic of Jiuyou Huangquan and the destruction of all phenomena. In the end, he did not prove the Tao through force, but used the method of "deconstructing language and pointing to the true nature" to refine himself into a "living Taoist code". He found the anchor point of "the unity of knowledge and action" in the fog of moral relativism, and used his own cultural context as a bridge to connect the chain of civilization that was about to be broken.
