Kouchuugun Shikan Boukensha ni Naru - Ch. 51.2

That's what happens when you run out of material to adapt and just make shit up on a chapter by chapter basis.

Sure, there’s probably some teething issues due to running out of pre-written material. But it’s also a callback to earlier in the series when Alan worried about the locals having access to powers that can put up a fight against pulse rifles and artifacts that exceed modern Imperial technology.

We're talking about medieval yokels here not WWI trench soldiers who are familiar with the concepts.

Bro wdym, guns and the likes already existed back in the Medieval times, and it's not hard to explain.
It's literally just, put the funny discs (or whatever shape the ordinance is, I just assume it's either the silliest of putty or mines) wherever you want stuff to stop existing then press the button to make it go boom.
