Tang Feng, an ordinary game designer, accidentally obtained a "time and space trading system" that can travel through thousands of worlds. Just when he was about to show off his talents, his greedy neighbor Fatty Wang designed to take away his core trading authority and trapped him in the low-level world. But Fatty Wang didn't know that Tang Feng had already buried a backdoor program at the bottom of the system. From the bronze age of the lost civilization to the steel city of steampunk, from the dragon's lair in the magical world to the data torrent in cyberspace, Tang Feng re-emerged as a villain. He uses modern business thinking to break down barriers in all realms, uses information differences to harvest resources from other realms, and uses game design concepts to reorganize the power structure. When Fatty Wang was ruling the high-level world, Tang Feng had quietly made plans to reshuffle the entire trading system.
