Poor Guy, I Have One Billion Combat Power in My Card

On the first day after his recovery, delivery rider Lu Yuan only had eight yuan and seventy cents left in his card. Then he discovered that the bank card balance was equal to combat power. One dollar is a little fighting power. Spending money makes you weaker, making money makes you stronger. Others rely on their talent for cultivation, while he relies on making money for cultivation. But the problem is... I don't dare to spend the money I've earned. Buying a bottle of water will drop three combat points, eating a bowl of noodles will drop fifteen points, and staying in a hospital will directly transform you from B level back to trash. The richest poor man in the world and the strongest clown. From eighty-seven to A-level, from takeaway rider to behind-the-scenes trader at Lingshi Market. He has a rule - I won't make money by beating you.
