This is the longest useless machine in Minecraft (almost)
Now you may say: But someone will build or already build a longer useless machine than me. Here is the thing: I will not stop, I will continue to add new things to the machine to make it longer and longer by looking for a new way to continue the chain reaction or even replace a part of a machine with something newer. My project is currently in 1.15.2 and this will also work in 1.16 so don't worry about my map is outdated. If you have new thing that you want me to add or find things that I can improved, just tell in the comments
(Update 7/13/2020: Sorry for not including the map. I am so stupid)
(Update 7/15/2020: A new version of my map has been released! Here is the link: https://www.planetminecraft.com/project/the-longest-useless-machine-in-minecraft-version-1-1/)
