She transmigrates into a cannon-fodder female character who doesn't survive three chapters.
The System tells her to follow the plot and frame the heroine, so she turns around and takes in as disciples the three male leads who will kill her in the future.
Her eldest disciple, Lin Jingzhou, is a cold, aloof sword cultivator in the original story. He killed her in his past life, but now he falls into demonic cultivation for her and thinks about defying his master day and night.
Her second disciple, Gu Changyuan, is the Demon Emperor in the original story. He killed her in his past life, but now he puts a soul-binding ring on her and can't stand anyone getting close to his master.
Her third disciple, Yun Yin, is a Buddhist saint in the original story. He killed her in his past life, but now he breaks his vows and kills for her, growing mad with obsession.
Jiang Xuanling: ???
I only wanted to raise a few kids. Why do you all want to do that sort of thing to your master?
Even more outrageous, she discovers that all three disciples are hiding the very same secret...
