After Being Transformed into Cannon Fodder, I Lost the Plot Line

[No female competition + no group favor + female protagonist and male protagonist + growth-oriented female protagonist + female protagonist who is greedy for money and lust VS male protagonist who is as beautiful as a flower] It wasn't until she was bound by the system that she was asked to change the villain's fate against the will of heaven. Lin Shuangbai was shocked to realize that the world she was reincarnated in was a book. System: What about the vigilance of the time travellers? What a classic male channel breaking off an engagement? Lin Shuangbai: Do you blame me? Whose family breaks off their engagement? The male protagonist and the villain share a fiancée! The system pouted: Who is to blame? If you weren't greedy for money and lustful, could you step on two minefields at once? What happened to being greedy for money and lustful? Lin Shuangbai refused to accept: My grandma is greedy for money and my mother is lustful. I am greedy for money and lustful, which shows that I have pure blood! System: Bah! Your Lin family has such a good family tradition! The system doesn't talk nonsense to her: in short, the world will collapse if the plot is not changed!

System: Your full text is less than 3,000 words long, why should you change it? Ha? Very good! Lin Shuangbai drew her knife and smiled: She is the young master of a dignified family, a rising star in the world of cultivation, and the future true immortal of the human race (self-proclaimed) who will overcome the tribulation!

From then on, Lin Shuangbai started her journey of protecting flowers by blocking gods from killing gods and Buddhas from killing Buddhas! Later, the decisive battle at the top of Shouyang Mountain The male protagonist was the first to collapse: Why does everyone want to stop me? ! Lin Shuangbai: Don't talk nonsense, it's just the two of us After the plot line collapsed and my mother didn't recognize it Demon Lord (Jiaohua) looked down at the messenger: Will you wait for me? Lin Shuangbai lay on the delicate flower's lap and touched the leaves (but she didn't dare to touch the petals): Of course, otherwise, wouldn't a person be lonely if he were immortal for eternity?
