Gu Muran, the former master of metaphysics, woke up and found that he had become the fake daughter of the Gu family.

The Gu family couldn’t bear the thought of their own daughter marrying into the Qian family, so they thought of the adopted daughter they had abandoned before.

The parents put their ideas on her again: “Since you and your sister’s kidneys are well matched, then give her one of yours, and she won’t die anyway.”

Gu Muran: Auntie’s things are not something anyone can touch easily.

In her previous life, her power of metaphysics was unrivaled in the world. She was once appointed as a national teacher to protect the common people of a country, and she was heard by the heavens. Even the emperor had to respect her when seeing her.

People: “Have you heard that there is a magician in Tianqiao?”

Classmate: “Who said that, our school is really good at it.”

Rich circle: “You are talking nonsense, the real magician is here.”

God of Medicine: “Hold on to dissatisfaction, Mrs. Lu is the most powerful.”

A certain woman smiled faintly: “Low-key, low-key, don’t fight, don’t grab, it’s all me.”
