Tutorial/High Effiency Nether Mine

First tutorial plse comment below srry for no pics

The first step is to get at least 6 diamonds 14 iron 1 chest 1 redstone dust 1 glass pane and 7 smoothstone.Next you use the glass smoothstone redstone to make a computer. Then you use that computer to make a turtle, you use 3 of your diamonds to make a diamond pick to make a mining turtle.Then you use your other three diamonds to make another diamond pick or drill(I prefer the drill because it makes the mining cheaper). Use your new drill to mine at least 20 obsidian(10 for singleplayer). Then go to the nether and got to your co-ords(expect divided by 8) to set up your nether portal to be a two way with the one at your home. Dig down to apx. 13. Set your turtle tunnel x( bieng how long you want your tunnel) as your terdy is tunneling you dig holes on both sides of the wall in this pattern wher h is hole and b is block HbbHbbhH and so on this covers a lot of blocks with very little digging, combined with each nether ore being worth 2 reg, ores if macerated it is very effective

Downsides

Dangerous, it pisses off the pigmen even if there are none near you now later some will get angry at you for no reason. Also nether ore blows up constantly to block this use a black hole ring to suck in the items or notice when the ores are smoking and break them or run!!!! Though, surprisingly, there is no lava down ther and zombiepigmen dont spawn that low combined with it lighting itself.
