章 148: CXLVIII. The Puddle

As he thought, that was not just water: the liquid was surrounded by a yellowish aura.

Dag said nothing to his companions and lowered himself to the ground, picking up a stone.

Reidar and Karl followed him with their eyes, trusting what he was doing.

Dag threw the stone into the pool of water, which splashed out of it.

After a few seconds, the rock ended up on the bottom, touching the metal ring and the surface of the pool returned flat like a board, continuing to boil.

"Did you see? It's just a puddle. Rather, let's figure out how to open that door" Karl said, stepping forward.

Just then, four of the runes engraved on the large rocky door glowed with intense blue light, activating a spell.

The water began to swirl, rising upwards as if it was a small liquid hurricane.

"Back!" said Dag to his friend, who before he even heard him had already turned back to his comrades, fearful of having activated some sort of defensive spell.
