After Completing the Tea Art, the Fake Daughter Returned to Her 70S

Yu Yin thought that her life would be smooth sailing, until one day, a girl came to her family who claimed to be the real daughter of the Yu family. Being kicked back to his biological parents who are the "Black Category 5" that everyone calls for beating? My childhood sweetheart's fiancé turned against me and refused to recognize him? Is the real daughter actually a book-wearing girl with a God's perspective? And she is a vicious female supporting character who will be slapped in the face by the real daughter of the heroine no matter what she does? Why don't you go so far? Yu Yin chooses to drown himself in the original book and get rid of the porcelain once and for all. As a result, after jumping into the river, she was inexplicably bound to the quick travel system. When she finished the task and then opened her eyes, oh, why did she go back to the day she jumped into the river? And this benefactor, please, you are the villain boss in the original book, why are you staring at me without blinking?
