The dark masters were confident that no one would be able to guess what this formation was, and so they didn't feel that much threatened by William's existence.
They sent another small group of high-end monsters, aiming to slow down William until the monsters they sent before would catch up to him.
William didn't know the danger that was rapidly approaching him, yet he could guess part of it. "These dark masters must have noticed my presence and sent those scary monsters before… That means they are watching me right now and will send more to stop me…"
He didn't have much choice if that happened. If he got surrounded, then it was the time to use his two monstrous weapons, buying himself a little time and creating a safe path for him to escape again.
As he was burdened by such disturbing worries, Sloth and other masters finally approached his location from a different route.
