Traveling Between Two Worlds to Become a Traitor

Lin Feng, a poor boy, was betrayed, but unexpectedly got a space ring that could open a portal to another world. The blue light door connects the modern and resource worlds. Here is the hard work of 996, and over there is wealth everywhere! Modern cheap salt, cold medicine, and small items have become luxuries that princes and nobles compete for in other worlds. Things that can be seen everywhere in other worlds are priceless on earth. By mobilizing resources from both worlds, Lin Feng made a lot of money and quietly became the richest man in the world. In other worlds, he was even more wealthy than any country in the world, stirring up troubles!
