Capítulo 1010: Tournament 3, Facing Soaring Heights (2)

"Since barriers are external, and cover a large area to boot, they aren't directly connected to the magic item creating them. Which means the devices can only handle what it was 'coded' to."

"But what if there is a method stopping external forces from interrupting the flow?" Ilmadia asked. 

"That would still cost mana, and weaken the barrier as a result. I think it's unlikely the barriers are advanced enough to actually stop my tampering, though."

'For them to be capable of that, they had to have something on the level of a Magic Crystal as their core. But that wasn't likely to be the case.' Eldrian thought. 

Eldrian highly doubted Soaring Height could get their hands on Magic Crystals so easily. This wasn't a case of money, but also of influence. Magic Crystals were too valuable to be sold to random players. 

Even he had trouble getting his hand on Magic Crystals. Even with all his connections in Taurus.
