The story takes place in the Middle-earth China, where the alchemy civilization is at its peak but its ideas are divided. The protagonist You Yaxin, as the only survivor of the taboo genetic experiment "Hundred Beasts Project", has the genetic origins of 108 mythical beasts sealed in her body. After escaping from the laboratory, she became anonymous in the border town "Qinglin Town" and became an herb collector. She started with the most basic "Hundred Herbs Illustrated Book" and embarked on a unique path of collecting herbs to build a foundation. During her practice, she unexpectedly awakened the spiritual wisdom of the "Bai Ze" gene in her body, and was able to glimpse the fragments of the Sutra of Cause and Effect. She also met the alchemist Mo Chen who adhered to the concept of "joining the world" and the mysterious guqin master Xian Wuyin.
As her cultivation level increased, the mythical beast genes in You Yaxin's body gradually awakened, which attracted the pursuit of the "Lingxiao Dan Pavilion" of the "Ascension Sect" and the competition of the "Ji Shi Fang" of the "Ji Shi Fang" organization. It also alarmed the ancient consciousness lurking at the "non-existence" level. She was forced to get involved in the dispute between the two factions over the ownership of the "Law Resonance Clock". During the natural disaster that broke out in the "Zhoutian Star Miasma", she used herself as "medicine" to reconcile the miasma and save all people. However, some of the rescued people became "sinners" because they received favors that transcended their own cause and effect. In the end, You Yaxin experienced calamity in the "Case of Creation of Heaven and Earth". She did not choose either extreme of ascension or joining the world. Instead, she used the realm of "Alchemy Origin Taichu" to embody the law of "simplicity", bridge the gaps in the levels of existence, let all laws return to the natural flow, and turn herself into a silent rhythm that nourishes the world.
