Qin Feng, a young man from the bottom, lent 500 yuan to his brother, but the brother was unable to repay the debt, so he cruelly abandoned his fiancée Su Qingxue, forcing Qin Feng to take her in to pay off his debt. When Qin Feng took her in, he accidentally bound her to a god-level treasure appraisal system and learned that Su Qingxue was the billionaire heir to the Su family and was poisoned. He relied on the system's treasure appraisal to counterattack and fight against the villains of the Su family who were seizing power. Qin Feng cured Su Qingxue, worked together to expose the conspiracy, and finally defeated the ultimate BOSS, helping her return to a wealthy family. Qin Feng also counterattacked from the bottom and became an urban strongman with wealth, strength and beauty. Adapted from the Tomato novel "I lent my brother five hundred yuan, and he used his wife to pay off the debt" [Please call me Laojiu].
