Capítulo 270: Black fin city (part 2) 

Besides the guards and a portal, at the other side of the magic array, Daimon could see the real structure of the prison, it was basically an underground structure with different portals and they were inside one of them, meaning this place was just a division of the prison. 

Seeing the guards glaring at them, Daimon landed on the ground followed by the girls, without waiting to be asked for, they showed them their tokens.

Daimon could guess the strength level of this division of the prison was in the middle, judging for the fact that these guards were only peak Lord ranks, that also explained why that merman Archmage was so confident when dealing with them, in this part of the prison he considered himself as the peak of the food chain, which ended up being his downfall.
