Kendo: I Have an Exchange Shop

A system without tasks, a Mutian that may come from the future. Mutian believed that there could be no free lunch in the world, so he set out to find a "hidden mission!" In order to find a hidden mission, I met a man with the same luck as the protagonist of the novel - Ye Chen. If you follow or protect this guy, you might be able to find a hidden mission. During this period, he entered the mysterious underground and through the mysterious "stickman mural", he learned about a long-standing stone man senior. Suspicions arose for a while, making the search for the "hidden mission" more complicated. This senior stone man seemed to be deliberately guiding Mutian to follow his plan. How could a person who might have traveled from the future be predicted? All this was obviously unreasonable. Ps: It belongs to the world creation category. You don't know anything in the early stage, but in the later stage you become a god and control everything behind the scenes.
