The BEST Concrete Converter - 60k / h

Hey! This is a concrete converter that converts around 60k items an hour!  It turns concrete powder into concrete blocks but can also be used for other needs!

You DON'T require much tnt because a single one gets duplicated repeatedly!

It is made as efficient as possible and shouldn't cause much lag!

If you are playing on a server and TNT duplication doesn't work, go to paper.yml and change the "allow-piston-duplication" option!

To use the farm:

1.    Fill all 3 chests with equal amount of blocks
2.    Turn on the farm
3.    Start placing the blocks!
