Raina looked at the barrier that came up before her with curiosity. She knew it was a runic barrier, but she did not know what exactly it could do.
Deciding to test the waters, Raina ordered the cannons to continue their constant bombardment. And the sixty Hell Hammer cannons did not stop their attack as a result.
The interesting thing was that no matter how many cannon shells hit the barrier surrounding the fortress, it did not even falter for a second. The cannon shots currently loaded in had the ability to damage both magical and spiritual protections. Although the effects could be minimal in opposition to its physical destructive capacities, many shots should have added up to great damage.
