Su Mianmian traveled back to the 1990s and became a temporary female social worker in a street office who not only received low wages but was also looked down upon by others. Although she looks slow to react, cute and easy to bully on the outside, in fact she has awakened the "Tianshi Daoyun" system, which can determine good and bad luck with one glance, and determine the outcome with one talisman. In this era when the market economy had just taken off and people were mixed, she worked in the neighborhood committee during the day to mediate neighborhood disputes (catching ghosts and exorcising evil spirits by the way), and at night she sold a peace charm on the black market for a sky-high price.
The male protagonist Gu Zixiao is a futures master who has returned from overseas. He believes in data and money and hates feudal superstition. When they first met, he regarded Su Mianmian as a charlatan. He not only ridiculed her but also tried to expose her. However, as Su Mianmian accurately predicted and resolved crises time and time again, Gu Zixiao's worldview collapsed.
The main theme of the book is that Su Mianmian "pretends to be a pig and eats the tiger", using the most innocent expression to slap the loudest face. In the later period, in order to recover Su Mianmian, Gu Zixiao not only had to fight his way out of his love rivals (all the big guys who had been saved by Su Mianmian), but also had to supplement his knowledge of metaphysics and start a long road to pursue his wife.
