'Those are certainly powerful barriers.' 

As I stood in line to enter the city and do a check again, I noticed that the barriers were especially powerful and varied, which I expected from a fixed city. 

I had already felt it, but the standard of these realms is superior to that of the Avaloria realm, and their technology in protective barriers was a reflection of this. 

No one wanted infiltration or internal attacks from their enemies, especially in a city, so they put a lot of effort into it. Just by me glancing over it, I realized that there were many barriers that detected humans in different ways. 

From the more standard ones, which check for pure mana from humans, to rarer ones that register human heartbeats, something most demons don't have, as cores replace it. 

The good news is that these detection barriers only work when you walk through them. Once inside, I didn't have to worry.
