Comments of chapter undefined of Only I Am A Reader

I hope the author will explain the origin of the system in the future, because everything has a cause and effect. There's no way MC has a system without a reason. One more suggestion for the shop within the system, I suggest the system not sell items in its shop because it doesn't make sense for the system to be able to create something out of nothing. Only God can do that. A shop selling knowledge and skills makes more sense in my opinion. Thanks for the chapter, great job author.
