I Can Upgrade My Talent In Everything

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.

As he opened his eyes, Fein\'s gaze fell upon a map of the North. His mind began to race with possibilities, strategizing how he could use his new spells and experience to further his ambitions.

Fein knew that the battle had only just begun, and he was ready to lead his shadow army to victory once more.

Rain Meteorite: This spell summons a barrage of meteorites that rain down from the sky, causing massive destruction to everything in the area. The meteorites are made of a special material that is highly explosive upon impact, creating a fiery explosion upon contact with the ground. However, the spell requires a large amount of mana to cast, and Fein can only use it once before needing to rest and recover his strength.

Hellfire: This spell conjures a powerful flame that burns everything in its path. The flames are black and purple in color and burn much hotter than ordinary fire, making them difficult to extinguish. The spell can be cast from a distance, and Fein can control the direction and intensity of the flames with his thoughts. However, the spell also requires a great deal of concentration to maintain, and Fein must remain focused in order to control the flames.

Mighty Explosion: This spell creates a massive explosion of dark energy that engulfs everything in its path. The explosion is powerful enough to destroy entire buildings and cause significant damage to the surrounding landscape. However, the spell is extremely draining on Fein\'s mana reserves, and he can only use it once before needing to rest and recover his strength. Additionally, the spell takes several seconds to cast, during which time Fein is vulnerable to attack.

"Didn\'t expect I could also obtain spell killing demons." Fein smirked. But when he thought of it, Demons have no other abilities than their magic power and spells.

"Rain Meteorite," he whispered to himself. "A spell that calls down a meteor shower from the heavens. Imagine the devastation it could cause in a crowded city, or an enemy stronghold. Oh, the screams of agony and fear would be music to my ears."

He opened his eyes and his smirk widened. \'But it has its limitations. The range is limited, and it can only be cast once every month. I must use it wisely.\'

He then turned his attention to the second spell, \'Hellfire.\'

\'Ah, a spell that conjures flames of the underworld. The mere thought of it sends shivers down my spine. It could burn down an entire army, or a castle. Imagine the power I hold in my hands.\'

He chuckled darkly. \'But it also has its limitations. It drains a significant amount of mana, and it can only be cast once every two months. I must be careful not to waste it.\'

Finally, he contemplated the last spell, \'Mighty Explosion.\'

\'A spell that creates a massive explosion, enough to obliterate anything in its radius. Just the thought of it sends my heart racing with excitement. It could take down entire cities, or decimate a fleet of ships. Oh, the possibilities are endless.\'

He took a deep breath and exhaled slowly. \'But it too has its limitations. The range is short, and it can only be cast once every three months. I must choose my moment carefully.\'

Fein leaned back in his chair, his mind racing with ideas on how to use these new spells to his advantage. He couldn\'t wait to see the fear and panic they would cause in his enemies.

\'Probe!\'

Memories of his weaker days flooded his mind, the days when he would struggle to defeat even the weakest of demons. He couldn\'t help but marvel at how far he had come.

As he looked back, he remembered the countless battles he had fought, the sacrifices he had made, and the training that had transformed him into the powerful abomination he was today. It was a long and arduous journey, but it was worth it.

Fein couldn\'t help but feel a sense of pride as he thought about all the battles he had won, and all the demons he had defeated. But at the same time, he knew that he couldn\'t afford to let his guard down. There were still many more powerful enemies out there, and he needed to be prepared.

Despite his nostalgia, Fein knew that he couldn\'t let his guard down. He had to stay focused and keep pushing himself to become even stronger. With these new spells at his disposal, he knew that he had the power to defeat any enemy that came his way.

Fein smiled as he closed his eyes and allowed himself to bask in the memories of his journey. It was a journey that had led him to become one of the most powerful degu user in the land, and he knew that there was no turning back now.

Suddenly, shadows enveloped Fein\'s room, engulfing everything in their dark embrace. The three shadow lords knelt before him, their faces awestruck and filled with reverence. It was as if they were in the presence of a deity.

Fein sat on his throne, his eyes scanning the shadows around him. He had been waiting for this moment, ever since he sent the shadow army to aid the humans. He knew that the battle had been won, but he wanted to hear it from the mouths of his most trusted servants.
