Reborn: Back to 1980 to Become a Tycoon

Author, are you here to make a joke? You buy it for thousands and sell it for millions. Do you think everyone else is a fool? Generally, people who do this kind of business will not investigate you. You can accept it, but others won't accept it. There are some fools in business. If someone buys it for a few thousand yuan, why spend millions?

I just read Chapter 2. The author has never experienced that era.
