Don't be afraid, the store has desert-specific vegetation. I don't know magic? It doesn't matter, if you take one magic pill, you will be the strongest master. The immortal dragon is arrogant? Hahaha, I'll just use an instant death suit and go invisibly to get an A! I will kill you after you are resurrected, hey, just for fun! Is my territory information too backward? What kind of scientific research are you doing? You can buy it directly on the Internet. What, the orcs are too ugly? You deserve the Painted Skin Professional Certificate!
