Fourteen years old Su Bei almost died when she had a high fever, got transmigrated into another world and finally knew a shocking truth–it turned out that the world she was originally in was just a novel and her whole family were villains.

The woman who gave birth to them was the cannon fodder in the novel. She and Su Xiaobao were written like this in the extra chapter. One was a little bastard who tried to bully the male lead’s daughter and eventually got thrown into prison and the other one became an escort, who after having failed to seduce the male lead, was killed by an evil director. They also have a dad whom they never met and was the biggest villain in the book.

Back to her original world, the first thing Su Bei did was to take Su Xiaobao and find their father.

Su Bei: Su Xiaobao, quick, call him.

Su Xiaobao: Call him what?

Su Bei: Call dad.

Su Xiaobao: I don’t want to, do it yourself.

Su Bei: Dad!

Looking at these two dirty children in front of him, Mr. Qin’s eyes showed disgust.
