Good lord, too much stuff on this game.
i found a cave with lava, diamond, iron, obsidian and water also red stone.
i ended up creating a compass to look around the surrounding.
I was looking for clay, because wood house burn, yes i dropped a bucket of lava by mistake. so i was forced to flood the house (note: an emergency anti-fire water block should be added)
i found that the area i was previously lost...is just behind a big mountain near my house.
