Lu Yuan was accidentally bound to the money-making exchange system. As long as he keeps making money, he can unlock high-end technology: starting from earth technology, gradually controlling solar system technology, galaxy technology, and finally redeeming the secret key of the entire universe civilization. When he relied on his wealth to start interstellar trade and build planetary fortresses, he discovered that the earth was just the starting point for the transition of civilization. Money could not only change destiny, but also buy the entire sea of stars!
