Fein sat at his desk, deep in thought as he reviewed the previous events that had just taken place. Suddenly, his mind was flooded with a rush of information - massive experience points and three S-rank demon spells appeared before him.
A smirk crossed Fein's lips as he realized that his shadow army had succeeded in their mission. The power of these spells was immense, and he knew that they would give him a significant advantage in any future battles.
Fein closed his eyes and let out a deep breath, savoring the thrill of victory. The Rain Meteorite, Hellfire, and Mighty Explosion spells were among the most powerful he had ever encountered, capable of leveling entire cities and leaving nothing but ash in their wake.
He could already feel the rush of power coursing through his veins, as though the very essence of the demons he had slain had infused his being. Fein knew that with this newfound strength, he could conquer any foe that dared stand in his way.
