In an age when spiritual energy is waning, evil spirits wreak havoc across the world.
Hong Lian is an ordinary high school student. After accidentally entering an evil spirit's domain on her way home from school, she gains a sacrificial spirit from five thousand years ago. Forced by circumstance to become a spirit medium, she joins the Central First Academy, where the great clans gather, and draws the attention of every faction.
At the academy, she meets Shen Yan, who claims to be a transmigrator. To her surprise, she learns that she is a member of the villainous organization in the novel Sacred Light, from another world. Yet to protect her family, Hong Lian still chooses to join the villainous organization, Emperor-Slayer.
Hong Lian finds the whole situation exasperating. She's just an ordinary person, yet she has the protagonist-like trait of possessing a five-thousand-year-old sacrificial spirit, and she's also joined a villainous organization. She wants to give up and laze around, but fate won't let her.
As she battles the Human Emperor and maneuvers against the righteous factions, the truth from five thousand years ago gradually comes to light.
She doesn't yet know that the age of waning spiritual energy began because of her, and that the course of fate has already changed.
