What to Do? Dressed as a Vicious Cannon Fodder Female Supporting Role!

(There is no CP, but there is some smoking. The supporting characters will not be brainless. The intersection with the two original protagonists is mainly in the later stages. The early and late stages are more about the heroine cultivating immortality, constantly fighting monsters and upgrading and making friends. The plot is more relaxed and passionate, and it is occasionally mixed with slap-in-the-face plots. I hope you will like it!) Li Qu'er once passed through the book and became a vicious female supporting character with good talent but a bad mind. All day long, she not only antagonized the heroine but also followed the male protagonist to seduce her. In the end, she was killed by the male protagonist with a sword for framing the heroine... Recalling the contents of the book, Li Quer vowed never to embark on the same path as his original self again! He has the original talent and a normal brain, but also has some mutations due to the book... With these things here, why worry about not becoming an immortal? What kind of hero and heroine? Get out of here, everyone! She just wants to become an immortal!
