Excuse my language, but F#CKING FINALLY! That an author points out this exact scenario.
It's always bothered me when they summon people right in front of their monarchs/heads of state/important people. What if they summon an armed lunatic (exactly the MC in this story) or someone with ANOTHER WORLD PATHOGENS that the locals have NO IMMUNITY for?! Or three dozens of other deadly scenarios.
This is what would happen you stupid idiots, who were created 5 min ago along with your entire universe.
Pardon my language!
