The Cannon Fodder Female Protagonist in the Book, I Joined the Villain Sect Overnight

[Villain + Unforgiveness + No CP] Yunyi accidentally traveled to a dog-blood group pet novel due to her "big luck", and became the cannon fodder female supporting character in it with the same name as herself. As a stepping stone to the group-favorite heroine in the original novel, Yun Yi is fully aware of her own fate and its misery. In order to change her fate as cannon fodder, Yunyi ran away with a bucket overnight, but accidentally joined the villain sect in the book. Everyone in the sect was either crazy or a villain. In order to prevent his villain brothers from meeting their originally planned tragic ending, Yunyi had no choice but to prevent them from going dark, and used the attribute points rewarded by the system to continuously improve his understanding, qualifications, and luck, and ultimately led the sect to prosperity.
