A whole family of villains and cannon fodder, with the lucky junior sister leading the way in surviv

Wen Lingyu transmigrated into a book and became the protagonist of a beloved novel. With her lucky charm attributes, she only needed to wait to win without lifting a finger.
But the plot suddenly took a turn. The future senior brother who treated her better than his own father suddenly pierced her chest with a sword and took away her spiritual root.
The body was abandoned in the wilderness.
......
She was rescued and taken back to the new sect, but the situation was dire; her senior brother was very handsome.
Wait, isn't the eldest brother the demon lord who later became the ruler of a region in the book?
After meeting the senior brother.
Song Qi'an said, "Junior sister, you're so cute. Come here and let your senior brother pat your head."
*
The second senior brother is a half-baked medical practitioner, but he has unusual hobbies.
"Junior sister, come and try the dishes your second senior brother made."
Wen Lingyu held a dark, mushy mound of food and looked at her fourth senior brother, who was engrossed in eating, with a sense of existential dread.
*
The third senior brother didn't like cultivating.
One day, he suddenly saw Wen Lingyu do a set of radio calisthenics and stared at her with shining eyes.
"Odd changes to even."
Wen Lingyu: "The sign indicates the quadrant."
The third senior brother lifted up his junior sister, who wasn't even as tall as his own leg, and exclaimed, "My dear!"
*
The fourth senior brother was the most normal; he cultivated diligently, but lost his sect because he got lost.

Faced with the sect's dead end, Wen Lingyu sighed to the sky. She was, after all, the protagonist who had transmigrated into the body of a protagonist. Shouldn't she be a natural-born cheat?
She went to find the cultivation technique mentioned in the novel, but it was nowhere to be found.
The spirit beast mentioned in the novel—she went to find it, but it disappeared again.
Who stole her cheat code?
......
If you've lost the top-grade cultivation technique, no problem, there's still the heavenly-grade one.
The high-level spirit beasts are gone, but that's alright, there are still ancient divine beasts.
