Metropolitan Supremacy System

In the aftermath of a car accident, Yang Ning has inexplicably gotten a set of abilities. He seems to have entered a game-like system. In the real world, there are attributes and tasks, warehouses and shops, and the ability to identify and view information on antiques. He used this ability to get into the antiques market and gain dominance in it.

What else will he do? Oh, pretty girl, come and buy my wares! I promise i won't cheat you! Maybe? Shut up, system! Don't you dare cheat me too!
