The world of cultivation has fallen into decline, and spiritual energy is scarce. Li Qingfeng, once a genius of the sword, has become a menial outer disciple after his spiritual meridians were damaged. He now watches over an abandoned library pavilion. By chance, he discovers an ancient text describing the path of ancient body cultivation: one needs no spiritual roots, for the body itself can serve as a vessel. By tempering one's bones, muscles, and flesh, one can still attain the Great Dao. He decides to embark on this arduous path of cultivation, forgotten by the times, determined to return to the immortal path through the most painstaking means.
