Going Through A Checkpoint

"What? I can't leave?"

Hearing the astonishment in the flame sprite's voice, Merlin asked in a hurry.

The flame sprite fell into a deep thought for a moment before saying, "You could go and give it a try. See if you can leave."

Merlin gave the flame sprite a suspicious look but he still turned around and darted into the hole, coming out on the first floor of the ancient tower.

There was not a single soul on the entire first floor. It was extremely quiet.

Immediately, Merlin came before that thick slab of stone door. Previously, Wizard Riesen had set down this stone door to trap Merlin in the ancient tower.

"Furious Flame!"

Merlin immediately cast Furious Flame. For a few moments, scorching high temperatures rose and even caused some explosions. Nevertheless, there was not the slightest bit of effect where the stone door was struck.

Hence, Merlin raised his hand and pointed at the stone door forcefully with his white finger.
