A person is immersed in the world of novels, and fails to follow a certain plot. She is transported to a world of immortal cultivation by the "portal from another world". Yes, it is the novel she is reading, and she suddenly becomes the heroine's early villain, the Master Demon! Bound to a special system, she only needs to complete the plot of the original owner before she can go back.
But when she is done, can she really go back?
Intention: Maybe there are too many misses in the world, but this time I will hold you tightly and never let go!
