After fresh graduate Meng Yu is abandoned by his money-loving girlfriend, the price depreciation system is accidentally activated. Global prices plummet a billion times, and only his savings are immune. After becoming the richest man in the world overnight, he met Murong Qianyu, the daughter of a wealthy family, and started on the path of slapping his ex-girlfriend in the face, rectifying his workplace, and returning home to benefit his fellow villagers. During this period, he founded "Meng Yu Holdings" to develop super batteries and broke the international technology blockade. Not only did he reach the top in the business world, he also found a home in his emotions and wrote a counterattack legend in which wealth and responsibility coexist.
