Ultimate TNT Raid farm

Raid farm that stacks raids on top of one another, and the fastest one there was when it was built. The overworld side runs the raids, the mobs travel through portals to the nether, and a carpet mod bot kills them with TNT. The creator measures 2.24 million drops an hour, of which 1.19 million are emeralds and 84400 each of the witch drops. This is a technical build rather than a tutorial: you get two litematics and a world download and are expected to work from them. It is also a server load as much as a build, 13 mspt on the creator's own machine with Lithium installed.

The 22.4 million figure shown in the edit is a typo. The creator corrected it to 2.24 million himself, and that is the top comment on the video.
The bot running the TNT is a carpet mod player, confirmed by the creator. There is no version of this farm that runs without one.
