The Weird Gate

In the next hour, loud noises started to echo from the direction of the base, meaning the battle already started. William spread his spirit sense and could see parts of what the king and others did.

They took this base as a fort and started hunting all the enemies coming from the upper surface.

He spotted monsters and dark masters flooding from up there, passing through the holes, and ending up falling into the deadly traps the masters laid already. They couldn't get past the traps, as there were tons of masters waiting around, killing everyone and everything falling from up there.

The enemies poured forces like endless rain, and it was clear if they persisted like this, nothing would change. 

"They have dark masters, and that means they'll find another way to come here," William slowly muttered, moving his senses towards the king and other high-end masters out there.
