Really fun chapter!! I guess I'm curious about how exactly the fortifications would work digitally and how much work/effort is put into that since it's not exactly clear to met, and we're still early into the story, with the Black Box probably not making an invasion just yet. And what do the troops do? At this point, I can't imagine them being typical of any sort, so are they technicians/engineers of sorts? LOL

The Messenger Pigeon QR Code part was really funny, and I'm personally hoping we get Bian Jin witnessing her shimei being hit on via this in the future.
