Sangyue is a gifted young girl from Miaojiang, known as a genius in raising Gu. In her previous life, she devoted herself to cultivating countless rare and powerful Gu, only to have everything stolen by the fake Saintess Caihe. Framed as a thief, Sangyue was thrown into the Snake Pit and died a tragic death.
When she awakens and returns to the past, Sangyue believes she has been given a second chance to change her fate. However, she soon discovers a horrifying truth: Caihe and the High Priestess Wuma secretly exchanged her and Caihe’s destinies through a forbidden ritual. Because of this changed fate, every Gu that Sangyue personally raises will recognize Caihe as its true master. No matter how much effort she puts in, even the rarest Gu she nurtures with her own blood and heart will betray her at the most critical moment.
Facing repeated betrayal from the Gu she created, Sangyue falls into despair. She begins to question whether she can ever escape the fate that has been forced upon her. In her darkest moment, she accidentally enters the hidden cave of the previous Saintess and discovers a long-lost forbidden technique.
Standing before the endless Snake Pit where she once met her death, Sangyue looks back at the blood and hatred connecting her past and present lives. This time, she refuses to remain a victim of fate. With the forbidden technique, she begins a new path where she will no longer rely on others’ recognition but will become the true master of her own destiny.
The fake Saintess who stole everything from her will eventually face the consequences of her deception, while Sangyue will reclaim the power and identity that were taken from her.
