Computer City Profiteer, Customers Begging Me Not to Go Bankrupt?

Jiang Li traveled through the parallel world and bound to the [Computer City Profiteer System]. As long as you install the machine for customers and earn the price difference, you can get points to exchange for future technology! But he found that the world's technology was backward, and computer technology was still at the beginning of the century. Optical drives and floppy disks are still mainstream, mechanical hard drives are ridiculously expensive, and independent graphics cards are unheard of. So... "Boss, a computer with 1G of memory only sells for 2,999? Are you sure you're not losing money?" "A 128G hard drive only costs 1280, and there is a 50% discount event? Are you doing charity?" "Please raise the price! If you sell like this, we are afraid that you will go bankrupt!" Facing the moved eyes of the customers, Jiang Li fell into deep thought. What I sell is junk configuration that has been out of use for more than ten years! Why do you think I have a conscience? "Sorry, everyone, I've already made money." "You're begging me on your knees not to go bankrupt?" "Then I can only continue to be a conscientious profiteer!"
