INVASIVE CRACK.
It was the worst type of dungeon known to humankind yet.
Invasive Cracks were deceptive. They would appear as a normal dungeon, then it would trap the Hunters inside before it released the monsters to the surface.
More often than not, those monsters were man-eating monsters.
Invasive Cracks were currently the most dangerous type of dungeon to exist because the gate itself was pretty much "alive." It could think, so it could also hide itself from the Hunters. And Invasive Cracks would only disappear if the gate was destroyed.
Unfortunately, that was the type of dungeon that greeted Semi as soon as she arrived at the destination where the System dropped her off.
As expected, it was a pandemonium there.
Everything was burning, and a few monsters were sighted.
Fortunately, the Special Forces was already there.
