The Zhang family has lived a quiet life in Yunjiang Town for generations, providing medicines to the commonfolk in the family-run apothecary. Using texts passed down through the family, they create potent medicines through the exotic techniques that their ancestor had termed 'alchemy'. Once a year, they provide pills and elixirs through the teachings inscribed within their family scrolls, journeying up Mount Qingliu for the initiation of new junior members of the Yangjian Sect at the end of their training.

These arrangements have held for generations. Now, however, the young Zhang Huoyun begins to question whether more secrets lie within his ancestor's cryptic words. What is the nature of the soul, and why did his ancestor speak of discovering the immortality that cultivators have long been searching for?

A single event will drive him to seek answers for the questions that have plagued him all his life, and along the way, perhaps enter the realm of cultivators himself.
