When young Gu Changsheng first entered the Taoist temple, he encountered great changes. His master was killed by the mysterious female demon "The Holy Mother", and he was also imprinted with the mark of the black lotus. In order to protect himself, he practiced hard for five years behind closed doors. After he came out, he found that he had been involved in the conspiracy vortex of "The Night Walk of Monsters". He relied on the purple sky thunder that he had cultivated to slay demons and eliminate demons, and discovered the secret that Shangxiang Chengxin could help him achieve enlightenment. With the help of Xia Xinyu, Liu Ruoxue and others, he traced the truth along the way, rapidly improved his strength, and successively foiled the evil plot to cause trouble in Jiangzhou. In the end, he had a decisive battle with the mastermind behind the scenes, the Holy Mother, and broke through to the Nascent Soul realm to seal it, but this also led to a more powerful enemy, the "Holy Lord".
