As they learned that, they started to do the same as him, even using any war weapons that could explode, even arrays were used!
They spared nothing to take down these monsters and burn the fog supporting them. As they progressed forward, at last, they started to see the results of this.
Monsters stopped growing stronger the deeper they advanced. In fact, they grew weaker, as if they didn't get enough time to evolve or get support from the fog.
As William's adventure was seen by all the high-end masters, they knew about the ground monsters and were pretty prepared for them. Once they appeared, a small team of high-end masters would sprint forward, taking care of them in the shortest possible time.
As they collaborated together, things became much easier and their losses plummeted by a huge margin.
Seeing such a result made everyone hyped for doing this. They started picking up pace and didn't fear the same fate as William.
