Fairy Tail:Celestial Tempest [NaLu]

Training Part 3

Rimuru stood with Lucy in the heart of the dense forest, where the air was thick with magic. "Today, we'll begin your training in the Void Magic," he announced, his voice solemn. "This is a powerful and dangerous form of magic. Use it wisely."

Lucy nodded, her eyes filled with determination. "I'm ready, Rimuru."

Rimuru demonstrated the basics, creating small voids that absorbed light and matter. "Feel the emptiness within you," he instructed. "Let it become a part of you. Channel that emptiness to create a void."

Lucy closed her eyes, focusing on the sensation of emptiness. Slowly, she extended her hand, and a small void appeared, swirling with dark energy. "Like this?" she asked, her voice tinged with awe.

Rimuru smiled. "Exactly. Now, let's practice controlling it."

For months, Lucy trained rigorously, mastering the creation and control of voids. She learned to use them defensively, absorbing attacks, and offensively, unleashing destructive power.

As the seventh year began, Rimuru introduced Lucy to the Black Flame and Black Wind spells. "These are among my most powerful offensive magics," he explained. "The Black Flame can burn anything, and the Black Wind can slice through the toughest defenses."

They practiced for weeks, Rimuru guiding Lucy through the nuances of each spell. "Focus on your intent," he advised during a session. "The Black Flame responds to your will. Let your anger and determination fuel it."

Lucy concentrated, her eyes narrowing as she summoned a searing black flame in her hand. "I can feel it," she murmured, the flame flickering ominously.

"Good," Rimuru said approvingly. "Now, direct it towards your target."

With a fierce cry, Lucy unleashed the Black Flame at a boulder, reducing it to ash in moments. She grinned, exhilarated by her newfound power. "This is incredible, Rimuru!"

"You're doing well," Rimuru replied, a note of pride in his voice. "Now, let's move on to the Black Wind."

The training for the Black Wind was equally intense. Rimuru demonstrated the spell, creating razor-sharp gusts of dark wind that sliced through trees. "The Black Wind is about precision and control," he explained. "Let it flow through you like a blade."

Lucy practiced tirelessly, eventually mastering the art of summoning and directing the Black Wind. "I did it!" she exclaimed one day, watching as her spell carved through a line of targets.

Rimuru nodded, satisfaction in his gaze. "You're becoming a formidable mage, Lucy. But we still have much to learn."

In the eighth year, Rimuru introduced Lucy to even more devastating spells. "Megido is a powerful magic that rains down energy spheres upon your enemies," he explained. "And the Nuclear Cannon is a massive, destructive force. These spells require immense concentration and control."

They trained high in the mountains, where the landscape could withstand the destructive power. "Watch closely," Rimuru instructed, raising his hand to the sky. Energy spheres formed above, raining down with precision. "This is Megido."

Lucy imitated Rimuru, her eyes focused on the sky. "By the power of destruction, I command thee! Megido!" Energy spheres materialized and rained down, obliterating the ground below. She gasped at the sheer power of the spell.

"Impressive," Rimuru commented. "Now, let's work on controlling the spread and impact."

The Nuclear Cannon required even greater effort. Rimuru demonstrated, unleashing a colossal beam of energy that scorched the earth. "This is not a spell to be used lightly," he warned. "It can cause massive destruction."

Lucy practiced diligently, learning to harness and direct the overwhelming power of the Nuclear Cannon. Each attempt brought her closer to mastering it, though the strain was immense. "I won't give up," she vowed, determination shining in her eyes.

As the ninth year began, Rimuru decided it was time to teach Lucy the most complex and powerful ability in his arsenal: Gluttonous King Beelzebub. "This is not just a spell," he explained. "It's a unique skill that allows you to devour and assimilate your enemies' abilities."

They began the training in a secluded cave, where Lucy could focus without distractions. "You must feel the hunger within you," Rimuru said. "Let it consume and transform."

Lucy closed her eyes, focusing on the sensation of hunger. She extended her hand, a dark aura enveloping it. "By the power of the abyss, I call upon thee. Gluttonous King Beelzebub!"

A swirling vortex appeared, drawing in the surrounding energy. Lucy gasped, feeling the immense power of the skill. "This... this is incredible," she whispered.

"Use it wisely," Rimuru cautioned. "Beelzebub can grant you great power, but it can also be dangerous if not controlled."

For months, Lucy practiced using Beelzebub, learning to devour and assimilate various forms of energy and magic. She grew more adept with each passing day, mastering the skill with Rimuru's guidance.
