Who wants to survival, mine, in a cave... With no Monsters! It is not that adventurous, but a good idea for the faint-hearted! And if you are not a fool, there are also a lot of raw materials! It is not a super-mod, but I have done a lot of work!
How to make The portal:
The portal frame is maked from stone. For the ingniter you have to use this crafting recipe:
air. air. stone_block.
air. redstone_torch. air.
stick. air. air.
Here is the mod, have lots of fun!
