Modern student Qin Shu was reborn through books and decided to cultivate elixirs on the Xuantianmen selection day. She combines ancient and modern knowledge, diligently studies alchemy, saves money frugally, and accidentally rescues Xie Shiyuan who was seriously injured and turned into a snake, and they have been together since then. In the daily life of the sect, the two encourage each other to progress together, resolve difficulties with wisdom and goodwill, constantly break through their own limits, and finally use actions to reshape the way forward and escape their destined fate.
