[ 1.14+] 240K/H 6gt Sand duper & Concrete Factory

The duper is built at the end with the exit portal and the concrete factory in the overworld in spawnchunks Both the duper and the concrete factory are dustless 99.9% efficiency in TNT The recommended way to use it is to first activate the concrete factory lever and then go to the end to turn on the duper Credits: Markus and Bluecore, who made the 192k/h duper for overworld and used it as a reference to make the 240k one, which is basically the same If there is any problem or doubt, you can tell me :)
