Soul Exchange, Xuanmen's Legitimate Daughter Fights All the Way to the Capital

[The true legitimate daughter of the Hou Mansion + decisive killing + soul exchange + catching monsters + only killing but not crossing + catching ghosts + fortune-telling + true and false daughters + system] Jiang Yutong: I am short of money. Xiao Qingheng: Love money as much as life. Jiang Yutong did not wear books and was not reborn. Her soul was exchanged before death, and she was bound to the system of killing demons and becoming stronger. Being chased by a wolf demon, she 'accidentally' exchanged souls with the national master Xiao Qingheng. On the way back to Beijing, she relied on the secret skills of Feng Shui to catch demons and exorcise evil spirits, and became famous. The Imperial Master carried her body and fought all the way back to the capital, but was treated unfairly at the Marquis' Mansion. 'Jiang Yutong': "I'm only busy taking care of the evil spirits, but I'm not taking care of you, right?" Brother Shizi: "Concubines are just slaves with a higher status. My only sister is Yuwei." After knowing the truth: "What's wrong with the concubine? Why should we be so clearly separated when we are all members of the same family?" After being beaten violently: "Sister, you are our biological sister!" Jiang Yuwei's identity as a concubine was exposed and she showed her trump card: "I'm going to be the master's disciple soon, what are you going to do to fight me?" Jiang Yutong:… Xiao Qingheng: "Madam Mingjian, I really don't know her!"
