After a month of grueling and silent training, the instructor finally broke her usual reticence and initiated a genuine conversation with Lucifer. "Your progress has been remarkable," she said, her tone a rare blend of approval and authority. "But to truly reach your potential, you must now enter the Void Realm. It's a place where no magical energy can be harnessed externally. There, you will rely solely on your internal mana to strengthen your muscles and enhance your physical prowess. This is where you will begin your journey to becoming a sword master."
Lucifer listened intently, understanding the gravity of her words. He had trained extensively in magic, but the Void Realm offered a different kind of challenge. It was an opportunity to refine his physical abilities and merge them with his magical skills. After considering her advice, he decided to embrace the challenge and become a sword mage, excelling both physically and magically.
