章 302: 302 Art on reality

[El's POV: ]

The illusion magic cast here, the one with the highest rank a mortal could achieve, is intricate and very complex since it is practically a picture that one materializes through magic on the very fabric of this world.

It is not just some simple illusion that one could create with elemental magic or something that one could just get past with some trickery.

It's not just some magical illusion that Lucy could cut through or something I could dispel. It's not even something that one could force break with a powerful energy attack or something that has anything like a start or an end for reverse calculation.

This was not a door so the key wasn't going to work in it, and it was a place where not just anyone could stay for a long time to figure out its functions and structure.
