Begin with the Wandering Merchant and Conquer the Entire Map

The gray fog that polluted vitality appeared, and all places it reached became restricted areas, and humans were trapped in a narrow space. When humans huddle in safe zones and fight for power and profit, Ke Chen has already become a wandering businessman in the gray fog. Deep forests echoing with the chirping of weeping birds, deep-sea labyrinths with strange bones floating around, underground ancient cities engraved with mysterious words, cliff caves hidden in narrow secret passages... Elves who are isolated from the world, goblins who long for communication, goblins who hate foreigners... The boundless gray fog hides alluring opportunities and traps. In the depths of the gray fog where no one survived, Ke Chen lit up a new transmission point: "I exchanged the worthless things for good ones elsewhere. Being a wandering businessman is really a huge profit." … Safe zone, people praise: "Kechen, he is the pioneer who freed mankind from the birdcage." I'm just a businessman, just buy me defective products... Treasures!
