I Make Money in the World by Being a Profiteer

When I woke up, the system asked me to sell items to make money. I decided to be a profiteer and vowed to make money that I would never spend all my life. Although the names of my products were unreliable, the quality was definitely good. I wanted to drain everyone's money in every space and place, so that everyone would be willing to spend money on my products, and squeeze out all the last value.
