After the real daughter of the Jiang family fell sick, she became stupid and insisted on marrying the cold-blooded, cruel, and crippled Fu Jiu. Mother Jiang said, "So be it. She's a good-for-nothing anyway. I only asked her to marry in place of my sister." Father Jiang: "After you marry him, remember to ask 9th master to help your sister find a better marriage." The fake heiress said, "Sob, I feel so sorry for Sister, but… if you get beaten to death by the 9th master, the Fu family will compensate us a lot of money, right? I'm looking forward to it."

Fu Jiuxiao said, "With me around, no one will dare to laugh at you. Moreover, I will make them pay back tenfold for the pain that the Jiang family has caused you!"
