The Richest Man Started by Stealing Future Technology

Yu Xiao traveled through time and space into a gangster and gained the ability to talk to future celebrities. Therefore, he talked to future medical scientists and obtained a pharmaceutical formula to prevent hair loss and obtain a method to inhibit the spread of cancer... He talked to physicists and obtained the breakthrough technology of solid-state batteries and the key technology of nuclear fusion... This archipelago world is undergoing rapid changes under his promotion, but Yu Xiao himself doesn't care much about it. He just uses it to accumulate wealth and enjoy life, occasionally solve some minor troubles, and add some fun to the monotonous life, that's all. A few years later, the world discovered that the world's leading technology companies had a common controller, and that was a lazy guy.
