Ten thousand fathoms of Lingshan, wind and snow do not return. How can a mortal youth without spiritual roots defy the heavens and ask the Dao? Shen Qingci, son of a medical family in Qinghe Town, whose parents were harmed by the demonic path, enters Lingshan alone under the immortal master Si Jinxuan. The master bestows upon him three generous gifts: the ancient divine sword "Jingshui Liushen", the void magical artifact "Qiankun Yunshuinao", and the wordless pharmacopoeia tailored specifically for him, "Baicao Nilin Lu". Without spiritual power, he uses medicine to enter his body, refining his pulse with cold. From the wall-breaking of the frost-vein grass, to the cold-marrow flower entering the marrow, and then to the snow-dragon vine torturing the bones—seven layers of medicine sources and seven transformations, each reshaping tendons and bones in ultimate pain.
