Wu Xu has lived for twenty-two years and has always been an honest craftsman in the eyes of his neighbors who runs a small repair shop. No one knows that this dull and taciturn young man not only has a golden finger that can accurately see through lies and people's hearts, but he is also very good at cheating and psychological games. It wasn't until his biological parents came to visit that he realized that he was the wrong true young master of a top wealthy family. Upon entering the Jiang family, Wu Xu discovered that the fake young master Jiang Hao, whom he had fostered for more than 20 years, had recruited various charlatans to pretend to be masters and set up scams in order to secure his position, coax his adoptive parents into draining their family property, and also wanted to evict him as a "country bumpkin". Wu Xu continued to pretend to be a timid and honest person, and played tricks on all kinds of swindlers until they doubted his life. He exposed the scams one after another. Not only did he secure his position as the real young master, but he also became the nemesis of the charlatans.
