Before Wizards Ernie and Watson could even exit the cave, the entire cave was shaken by a huge bombardment, like the entire structure was quaking.
Flames, ice crystals, tornados… Almost every spell conceivable had been concentrated to full power and aimed straight at the mouth of the cave. The power levels of the spells were also vastly different. There were Fifth-, Sixth-, and even Seventh-level spells.

"Master, there's really no way to go out!"
Wizards Ernie and Watson hung their heads bitterly. They really dared not dash out again. If the horrible wave of attack resumed and landed on their bodies, no matter no how many layers of Defensive spells they wore, the impenetrable barrage of spells would kill both of them in an instant.
