Old Wilson found a few knights. They held shields in their hands as they protected Merlin while approaching the gate.
"Let's try it."
With only a thought, Merlin cast a fist-sized fireball instantly. This was only a normal Fireball. Merlin only wanted to test how sturdy this gate really was.
"Go!" Along with Merlin's yell, the fireball immediately flew toward the gate.
"Tsk tsk tsk."
The fireball crashed into the gate. Merlin did not cause the fireball to explode. Facing such a sturdy gate, the little fireball surely could not blast the gate off, so it could only burn a hole in the gate with its high heat.
However, this gate was exceptionally sturdy. Since the city gate was the last barrier to enter the city, its level of sturdiness was top notch.
Therefore, Merlin's Fireball only left a half-inch-deep hole in the gate, unable to burn through the gate.
