How to make shroomite/mushroom armor part 2

Okay,so you will need to go underground to find mushroom biome,destroy mushrooms with anything but pickaxe/drill and after destroying many mushrooms you shall get at least 1 mushroom seed(you may have to wait for mushrooms to regrow many times and destroy mushrooms many times before you get 1 mushroom grass seed) plant the seed in your 200-400 mud block above ground biome and afk it will take hours and hours for it to grow. Then once you have your own mushroom biome make sure all your other npcs have houses,I forgot once and had to make many houses in mushroom biome.

Once you have gotten the npc with a mushroom on his head,you need to get 1 platinum coin.to buys the auto hammer.
