Why Is the World Turned Upside Down?

I accidentally traveled through a completely upside-down world. I had a system with me, but it was of no use. It felt like a guide NPC that only explained everything I saw. But why do the top-quality spiritual stones in my eyes look like scrapped spiritual stones in the eyes of others? I am the same forever. The physique he saw was a super waste body. More and more discoveries suddenly made him feel how everything in this world is the opposite. A flash of inspiration occurred, hey, doesn't it mean that you can become an immortal just by lying down? Hey,,,, I have been lying down for two years, why am I getting fatter and weaker???
