Prison tech is a prison server where your goal is to get to freedom, by paying to move up through ranks, it requires a lot of time doing the same thing over and over. There is a few different routes you can take to get to freedom but they all have 1 finish line which is freedom.
Once you are in the server you can teleport to your first default block which is the D block. D block has no pvp expect in the maze, pig/chicken spawners, 2 Iron/Coal Mines and 2 birch wood mines.
To Make some basic money or to get started off with is to go to the pig/chicken spawners and get a reasonable amount of food which can sustain you, then you should go to the second birch wood mine and get approximately 5-10 wood logs which you can use to make a wood pickaxe with. Head over to the iron/coal mine and gather 9 stone to make your self a set of stone tools which can help you in the your future journey.
