Lin Chuan, a college student, was publicly humiliated by his ex-girlfriend and a rich second generation. In despair, he activated the "strongest dog-licking system" and received tens of billions in dog-licking money. He relied on the system to buy luxury cars, hotels, and donate huge sums of money, step by step to defeat his enemies and clear his reputation. He also thwarted the conspiracy of Lu Xingye and the Japanese forces at auctions, hospitals, casinos, and other occasions. As his strength continued to increase, Lin Chuan established his own business empire and eventually became the overlord that no one dared to mess with in Xinghai City.
