The castle and surrounding area was compressed into a boulder, so it wasn't exactly the same, but I know the series you're talking about.Reminds me of that isekai manga where MC got that barrier power. Whole castle just poof, gone out of existence.
Dude basically just photoshopped the castle out of existence.
You're right, he's probably using MSpaint instead.Needs some work with the background fill though.
-Are you the castle invaders!?!?That’s…uh…one way to clean up the crime scene…
The dude just fundamentally destroyed the governmental body for the entire civilisation. The civil war that results from this would cause other nations to invade (it's a fantastic opportunity). They are less likely to summon heroes, because the nation's defences are now non-existent… it would be too easy.I feel like this might provoke the opposite response to what they intended, some idiot is going to see a country summoning heros got wiped off the map and think some demon did it, which isnt exactly wrong I guess but i could definitely see more people being summoned because of this
