Chu Qin was injured and unconscious for three years. Not long after she woke up, she was faced with three difficult missions:
Her original body's righteous sect: Go undercover in the demonic Bliss Sect. Take advantage of their leader's illness and kill him.
System: Reform the villain, redeem the villain, clear the villain's name, and prevent the end-of-the-world finale.
Bliss Sect: We hear we have a mole. Find them, then kill them.
Chu Qin: Looking at the book that appeared in her mind palace, which clearly stated that she was the mole the Bliss Sect had sent to infiltrate the righteous sect.
...She fell into deep thought.
Who's the mole?
Who am I supposed to kill? Who wants to kill me?
Am I supposed to kill myself?
Everyone in the Bliss Sect was a villain, terrifyingly powerful and utterly extreme in temperament. She decided to keep her head down for now.
She'd expected to become the sect's punching bag, but somehow she became its darling instead.

She didn't know that from the day she returned to the Bliss Sect, they had already seen through her identity.
The Bliss Sect was in a land of extreme cold, and life there was incredibly dull. It was so dull that even the bloodthirsty killers couldn't be bothered to do anything to her. They just wanted to see what she would do.
She didn't know, either, that her System's voice wasn't a secret.
When faced with the fake friendliness of a yandere young master of the demon clan:
System: Hurry! Reform him! Teach him to be a sincere, friendly person!
Chu Qin: Nonsense. His yandere side is part of his charm. Don't you think he's cute like this?
A beautiful saintess had turned traitor against the righteous sect after her childhood sweetheart and fiancé fell for a delicate white-flower replacement. In her rage, she killed the scumbag and his replacement.
System: Hurry! Redeem her! Help her heal from her heartbreak!
Chu Qin: That's enough. Making things up is shameful. The pretty older sister and the white-flower girl are real sisters. The fiancé tricked the white-flower girl into killing the saintess to steal her golden core. She was just avenging her sister. What's there to redeem?
As for the other villains, no matter how much the System tried to brainwash the female lead, she could always refuse, slack off, and take her keep-a-low-profile policy to the extreme.
The demons who had initially been hostile toward Chu Qin: ...She really gets me.
Then she noticed them becoming gentler by the day, all smiling benevolently and competing to eat with her and train with her. They'd even give her head pats for no reason.
Chu Qin: ? Don't do that. You're scaring me.

System: Fine, fine. You may have a point about the others, but what about the big boss? If he doesn't reform, the world will end, and everyone will die together.
Chu Qin looked at the sickly, handsome man unconscious in bed.
The book said that although this big shot was frail, he was incredibly powerful. He'd arranged everything in advance and fused a weapon of mass destruction into his soul. Once he died, the weapon would automatically destroy the world. Then it would really be over.
After waking up, he heard Chu Qin sighing anxiously beside his bed every day.
"Big shot, please don't die."
"What will I do if you die?"
"Don't let them reform you. Reforming villains makes them three parts weaker, and if you're weaker, you'll die. I don't want you to die, boohoo."
The big boss being talked about: "..."
He could sense other people's emotions, and discovered that she wasn't pretending.
She was genuinely sad for him.
Born with an evil bone, he had borne everyone's hatred. Yet someone was crying for him.
