Just because you are turning the globe does not mean that you know the world. The fact is that human beings have explored only 1 percent of the ocean world and set foot on 50 percent of the land surface world, and if you include the underground part, then human exploration of land is the same as the ocean, less than 1 percent. And in this hundredth mile, there are mysterious areas that nature hides and does not want people to set foot in, which may be nearby, but they are not allowed to enter. There are also hidden secrets in the world, which are secrets that only those at the top of the pyramid know, such as Antarctica. And those spaces that are not visible to the world and are hidden by nature have a unified name - Yin Ruins.
