The Runic Heartprint loomed between Merlin's brows, and then out flew several mysterious runes, quickly forming a complex Runic Magic Circle which pressed down on the Runic Magic Circles in a distance.
"Crack".
With the help of the Runic Heartprint, the complicated Runic Magic Circles were broken in an instant, revealing a deep valley.
There was a cavernous hole inside the deep valley. Based on Merlin's observation, he discovered that the hole seemed to have been excavated in a deliberate manner. It must have been accidentally discovered by the Mill clan.
The hole must contain certain secrets. Otherwise, the Mill clan would not hide it warily with the Runic Magic Circles.
"Swish".
Merlin did not hesitate and stepped inside.
The passage was very dark, and a little damp, so Merlin extended a finger. A small, pale-white flame flickered to life at the tip of his finger, lighting up the entire passageway.
