Armadillo pit slime farm

A slime farm for 26.2 that needs no slime chunk and no swamp. You dig an 8x8 hole three blocks deep, replace every stone block around it with dirt so the silverfish have nothing to hide in, and cover the bottom with two rows of hoppers and campfires over a double chest. About 20 armadillos go on a separate campfire behind a wall, with one nametagged zombie trapped next to them so they stay curled up in their shells. To run a cycle you light the campfire and throw a splash potion of infestation, wait about two minutes while the silverfish pile up, splash them with oozing and open the fence gate. The silverfish die into slimes, the slimes burn on the campfires, and the slimeballs drop through the hoppers into the chest. There is no redstone in the build, every cycle is thrown by hand.

Ghionee would rather build a killing chamber and use a looting 3 sword than let the campfires kill the slimes.
