If youre familiar with CubicMetres Orbital Strike Cannon, then. you probably already know the concept of this one.

BUT if you arent and want to know the concept of this cannon then, it can send a block of anvil. at ANY coordinate you put in your own world.

this cannon requires a spreadsheet to give you the count and trims you have to put in the cannon settings. (NOTE! The cannon is a little inaccurate, as it launches the anvil 5-20 blocks away from your wanted target, which for me is good enough.)
