This is what the main world island looks like. There are three trees, a river and a mine on the island. 

There are many minerals under the island. 

This mine is updated this time. 

It's dark in the mine, so have a torch ready. Because there's a good chance there's zombies in the mine.

Going down the mine, you can meet a businessman. Can rest assured that businessmen will die, because they are invincible. 

He has something to sell the photos below.

Zombies, skeletons and spiders. 

But the brush cage doesn't lead directly to the mine.
