After Dressing up as a Cannon Fodder Female Supporting Character, I Had Sex with the Big Devil (Through the Book)

Bai Ying transformed into a genius that has never been seen in the world of cultivation for a century. The female supporting character was so madly in love with the male protagonist that she tried her best to please him and gave all her cultivation resources of more than ten years to the male protagonist. When the male protagonist was in danger, she stepped forward, but was chopped into pieces with a knife. Her cultivation was completely destroyed, and she became the laughingstock of the sect, becoming a loser who could be bullied by anyone. And not long after, the entire sect will know that she is a demon, and the male protagonist she longs for will stab her to death, kill the demon, and embark on the path of Long Aotian defeating rookies, completely forgetting that she is a stepping stone, and stay together with the female protagonist. Bai Ying: Whoever tolerates this is stupid, I won't be this cannon fodder anymore! Today I will let you two go to the crematorium to stay and fly together! (╯‵□′)╯┻━┻ So everyone in the sect discovered that Bai Ying, the loser who claimed to be a genius and never practiced, suddenly started to work hard to get better. Not only did he no longer humble himself to please Junior Brother Yu, but he also hung around the brutal and beautiful senior brother all day long, taking advantage of all kinds of training resources. Bai Ying successfully hugged her beautiful senior brother's lap and prepared to lie down comfortably. However, after reading half of the original novel, she didn't know that her senior brother was actually a cruel and pure demon. Until that day when the demon appeared, the righteous bosses suffered countless casualties. Baiying hid in a corner and saw that the legendary and feared young demon king actually had the same face as her senior brother... Baiying:... QAQ? ! ! ! And the sinister and cruel Demon Lord gently caressed her cheek, lowered his eyes and smiled lightly: "If Yingying refuses to love me, I will kill them all." Bai Ying: "......" Mission: Never compromise with fate
