Lu Linglong was originally the legitimate daughter of the Hou family, but due to an accident, she grew up in the countryside and became a little pepper that people from all over the country did not dare to mess with. After being found back at the Hou Mansion, she discovered that her parents did not love her, but wanted her to be a "substitute secret guard" for the sick and fake daughter, and even marry a living dead on her behalf. Lu Linglong overturned the table on the spot, relying on her market wisdom and brute strength to fight against her hypocritical parents and abuse the green tea and white lotus in the courtyard of the deep house. During this period, she met Yan Xiao, a scheming male protagonist who seemed to be just a low-level agent, but in fact held the court's intelligence network. The two reached an agreement with their own purposes: she would help him investigate serious cases involving the Hou Mansion, and he would help her gain a foothold in the capital and eliminate her enemies. From a stand-in to a chess player, Lu Linglong has made great progress all the way, making those who owe her repay a hundredfold.
