you were in a RLcraft world, which is a way harder version of the regular minecraft world, you, normally, start out with nothing and must make your way to the top, but things are a bit different, you can't just punch trees to get wood like normal, no, that will harm you, you must create flint tools first, like the flint knife to gather sticks and fiber so you can make other flint tools, also you need to drink water more often now as not only can you die from hunger, you can now die of thirst, weather also takes place here, being too hot or too cold in hot or cold biomes can hurt you, there are also many different creatures and other things in the world now, most of witch want to hurt you like mutant ants, wasps, bees, orcs, skeleton lords, golems, spiders, and other deadly beasts, there are also bears and goat-horse hybrids along with wolves and Dire wolves, but they aren't aggressive unless you hurt them first, there are also people like samurai warriors, pirates, bandits, and knights, but they all want to hurt you, some knights ride on horses to catch up to you faster, there are also dragons on the surface now and were extremely aggressive, it's possible to tame them but you must defeat them first, after defeating a dragon you can either slay it, or spare it and make it your pet, good luck
