As soon as Merlin stepped inside the dark cave, he felt a chill straight up his spine.
Although the cave was dark, it was nothing for a Spell Caster like Merlin. They had their Mind Power, so they could see clearly even in the dark.
Merlin was always walking at the front and was always on alert. As soon as he sensed anything, he would halt. After ensuring there was nothing wrong, he would continue his walk.
"Wait. What's that sound in front?"
Merlin suddenly paused and listened closely.
"Screech!"
The sound became nearer and clearer. Merlin's expression changed and alerted the others immediately, "Be careful. It may be the Dark Vampire Bats!"
As soon as he finished his words, they saw a gigantic red light appeared in the dark cave in front of them. Moreover, the light was approaching Merlin at an incredible speed.
"Frost!"
Merlin immediately cast his Frost and almost sealed the narrow pathway in the cave.
"Bang!"
