The Acacia Sect’s Supporting Actress Switches to the Path of Ruthlessness

I transmigrated into a book as a supporting female character in the Hehuan Sect. According to the plot, the male lead from the Immortal Sect would kill me with a single sword strike.

But the male lead from the Immortal Sect cornered me against a wall, his eyes red. “Why... won't you look at me anymore?” Meanwhile, the original story's great villain, whose cultivation manual I had stolen, calmly wiped his sword. “You cultivated my Dao, so you belong to me.”
