Dark clouds filled the sky as if a rainstorm was about to happen.
Merlin sat in a quiet room. He had already let Darknight and Lady Phillie guard the surroundings to notify him if anything happened. After all, in this unfamiliar Dara City, Merlin still had to be careful.
"Swoosh."
A Thunder Stone appeared in Merlin's hand. It was the treasure that he had obtained during the auction. Perhaps to others, it was only an alchemy material but if Merlin wanted to cultivate Thunder Fury fused with a Pandora Demon Ability, he needed the Thunder Stone.
Merlin was already very familiar with cultivating Pandora Demon Abilities. Since he did not have any Thunder-type Pandora Demon Abilities, he could cultivate it smoothly. Merlin first followed the procedures of the new spell and drew some patterns on his arm. When these mysterious patterns were drawn, they faintly modeled with the Thunder-type spells in his body, establishing an extraordinary connection.
