I had stupidly kept all of the iron and coal that I had in my inventory. With my sword, i traveled deeper and deeper. i finally reached the cave with the monster spawner. With my sword, went deeper into the cave but the world was lagging at the worst time. out of nowhere, i was hit by an arrow and a skeleton came out. he was nothing compared to the creeper coming. The creeper came right up to me and blew up. I spawned back up on the surface with nothing in my inventory. i knew my stuff was still down in the cave but i wasn't going risk it.
