Qin Shu joined the Dan Sect and was disliked by her senior brothers and had low spiritual skills. However, she excelled in the examination with her knowledge reserves. In order to win the "marrow-cleansing gold", she practiced hard day and night, and unexpectedly discovered that she had a special physique. During the trial in the mine, she encountered a tide of beasts, and the little black snake turned into a human form—the inner elixir was swallowed, and the demon king depended on her. Faced with competition from fellow sects and dangers in secret realms, Qin Shu's path to immortality is filled with crises and adventures.
