Gu Hengjia, the fourth young lady of Yongchang House, was falsely accused by her mother-in-law of being a witch. She was so tired of winning that she drank poisoned wine and threw her into a dry well. She faked her death and escaped, and returned to the capital three years later as the adopted daughter of the richest man in Jiangnan. On the first day of rebirth, the system "Tiangong Linglong Pavilion" awakens - as long as you change the fate of others and earn karma points, you can exchange them for business, medical skills, strategizing and other heaven-defying skills. She bought the house next door to the Hou Mansion and opened a rouge shop to make a fortune every day; she set up a grain store to keep prices down, so that the Hou Mansion farm could not make ends meet; she took advantage of the palace's taboo to kill her, and made her mother-in-law kneel in front of the palace gate to plead guilty. Her former husband, Xiao Yanzhi, stopped her with red eyes: "Hengjia, I know you're not dead. I'll carry you as my wife when I get home." Gu Hengjia shook off his hand, tore up the letter in public and said: "My wife? I want everyone in your house to kneel down and beg me to accept this letter of divorce." Tonight, she wants everyone to know that a merchant girl cannot kneel on her knees.
