Shen Qingyuan, a single mother, runs a maternal and infant store by herself and has her eight-year-old daughter Su Xiaoguai. Her life is difficult. One day, the daughter suddenly awakened to the divination system and calculated with her fingers that her biological father, who had been missing for three years, was actually Lu Chen, a billionaire. But Lu Chen has already been cursed by the Xie family's century-old blood contract. He has been trapped in the underground vault printing money day and night all year round. The money around him sucks his blood and becomes a human cash machine for the Xie family to continue their lives.
The old lady of the Xie family, Mr. Xie, relied on blood contracts to rob the fortunes of the three major families. Her granddaughter, Xie Yun, made things difficult for her at every turn. She set up a vicious plan to annex the Lu family's property, and even lured Lu Chen's fake fiancée Song Qingwan into the trap. Su Xiaoguai holds a full set of secret talismans and can see through conspiracies and deduce business opportunities. The mother and daughter join forces to fight back. Rely on the hexagrams to buy stocks at the bottom, find the Xie family's money-laundering shell companies, and gradually dismantle the other party's business layout.
In order to rescue Lu Chen who was trapped in the vault, they broke into the Xie family's ancestral temple and visited the ancestral tomb altar at night, fighting against formations and thugs. On the way, they met Zhou Mo, a technological upstart who was also persecuted by the Xie family, and formed an alliance. Su Xiaoguai continues to unlock the curse-breaking talismans, break the chains of the blood contract, uncover all the truth left behind by Lu Chen's mother, and uncover the shocking secret of Mr. Xie's ability to survive through the blood of living people.
While protecting her daughter, Shen Qingyuan assisted Lu Zhong in taking charge of the Hundred Billion Group and liquidating all the sins of the Xie family. After going through multiple dangers such as death in the ancestral hall, siege and pursuit, and secret clan battles, the century-old blood contract curse was completely shattered. In the end, all the Xie family's influence was wiped out, Lu Chen got rid of the treasury prison, and the family of three stayed together in peace and control of the business territory. The mother and daughter no longer had to worry about their livelihood.
