After the completion of the pouring of mercury into the magic formation, Xeron appeared at the crater.
He stood at the edge of the magic formation as his hands began to glow, and his mouth changed something softly. After a while, the magic formation started to glimmer.
Xeron suddenly stomped his demon's hoof onto the ground. A loud noise reverberated, and the entire volcano began to shake.
Like a major earthquake, the entire mountain was shaking, and many demons fell to the ground.
The magic formation that Xeron had them fill was actually an amplifying formation. He used the effect of this amplification and cast the Earthquake spell, letting the magic penetrate to the bottom of the volcano.
