"What?! How can it be?!" Thelgrun shouted.
The demons outside might be numerous, but the gate was very durable and its HP recovery was fast. Unless all the demons outside dealt damage to the gate at the same time, their damage shouldn't be able to offset the gate's HP recovery. There was limited space for them to crowd in front of the gate, so they shouldn't have been able to do that. They would need a siege weapon that dealt extra damage to structures to take down the gate.
What the people behind the gate were not aware of was that it was in fact siege weapons that were now firing at the gate. Or more correctly said, siege monsters. The ones dealing the most damage to the gate were three gigantic worm-like monsters. Their skin was reddish black and they had an extremely large oval mouth at the front of their bodies. From these oversized mouths, they shot acid-like giant balls that traveled a great distance.
