In the meantime, amidst the bustle of the town's activities, the Dragon in the human form was savoring a meal that was served to him.

He was indeed Aersus, who had just recently arrived in the Human Realm. After learning more about the castle where the Shadow Immortal was, he realized that it would be very difficult for him to fulfill his vengeance.

There were four True Immortals and even Demon Saints in the castle. Lastly, he heard about the two Dragons there

"It's impossible to fight the Shadow Immortal. I should just enjoy this world." Aersus muttered as he knew when to advance or retreat.

He doesn't plan to kill or injure his soul after arriving in this place with difficulty.

'Well, he probably forgot about me already It should be fine if we all forgot about that matter in the Mystic Soul Tower.' Aersus thought as he continued to eat

"Mhmm Human delicacy isn't too bad"

As he thought of this, a frown crossed his features, prompting him to rise from his seat.

He paid for his meal, a money he had stolen somewhere, and calmly followed the aura that was guiding him. It led him to a shadowed alley, where a broken mirror awaited.

Its fractured surface reflected a distorted image of the enigmatic figure that had captured his attention.

'Interesting I didn't think someone could see through my disguise.' He thought.

In a voice tinged with curiosity and suspicion, the Aersus confronted the mirrored apparition.

"Who are you? Why are you following me?" The echo of his query lingered in the alley, setting the stage for a convergence of destinies intertwined by threads of fate and intrigue in the mystical realm surrounding Vale's Castle.

"I am Mennena, an ArchFey," she declared with an air of mystique around her. Her ethereal presence, however, seemed to have weakened a lot in front of this powerful dragon

"Are you harboring intentions towards the Shadow Immortal's Castle?" Mennena's voice resonated with a subtle curiosity, prompting Aersus, the Dragon cloaked in human guise, to pause in contemplation.

"Mhmm? And why, pray tell, do you inquire of my intentions?" Aersus responded, his gaze meeting hers with a glint of amusement dancing in his eyes.

With a knowing smile gracing her lips, Mennena extended another offer veiled in intrigue, "I possess the means to aid you in your infiltration. Within the depths of the castle lies an object of great significance to me, yet the arrangements of Dragon Arts and Formation Arts encircling the fortress stops my entry."

Aersus chuckled softly, a rumble of amusement reverberating through the alley.

"Attacking the Shadow Immortal's stronghold would be an exercise in futility," he remarked, his tone tinged with a hint of respect for the formidable defenders within.

"The castle harbors not only the enigmatic Shadow Immortal but also four True Immortals, four Demon Saints, and two elusive Dragons. It is a world of insanity to dare to confront such a stronghold of strength."

Simultaneously, as their conversation unfolded, Aersus invoked the keen insight of his Dragon's True Sight, peering beyond the mystical veil to discern the true nature of the enigmatic presence conversing with him through the fractured mirror.

"Indeed, a formidable lineup," Mennena acknowledged, but her gaze remained calm.

"What if our roles were to intertwine harmoniously? You can help me break barriers, and I, the adept infiltrator will take something from the Immortal's domain. Does this arrangement pique your interest?"

Aersus, intrigued by the proposition, raised an eyebrow in silent contemplation.

"An intriguing proposal, but what incentive do I have to participate in this risky venture?" he inquired, his eyes betraying a glint of interest in the promise of a reward.

With a graceful gesture, Mennena unveiled a tantalizing offer, "Should you aid me in breaching the castle's defenses, the Golden Key, a medium used to enter the Prison Realm, shall be yours to wield once my purpose is fulfilled."

The mention of the Golden Key, a mystical artifact shrouded in ancient power, piqued Aersus's interest, kindling a spark of ambition within him.

"I trust you can deliver on this promise," he mused, his gaze meeting hers with a newfound sense of partnership.

***

After two days of meticulous planning and preparation, the fateful moment arrived for Mennena and Aersus to embark on their daring mission.

As the moon cast its silvery glow over the landscape owned by the Shadow Immortal, the duo were ready.

Mennena was still in her mirror, but this time, there were already hundreds of broken mirrors in the forest. They were going to challenge the formidable defenses of the Shadow Immortal's Castle.

"I will start now" Aersus said.

Soon, his form started shimmering with draconic power and underwent a breathtaking transformation, shedding his human guise to reveal the majestic visage of a blue dragon!

Roaaarrr~

With a resounding roar that echoed through the night, he unleashed the primal essence of his draconic aura, channeling ancient energies to invoke a devastating Dragon Spell!

The atmosphere was soon filled with Fire and Wind Elemental Force as Aersus unleashed a torrent of searing flames and a tornado imbued with the might of a true Dragon!

He aimed at the first of the seven-layered barrier that shielded the castle's inner sanctum.

Boom!

However, instead of just hitting the first layer of Formation Arts or Barrier, something unexpected happened.

Each layer of the protective shield had started quivering and buckling under the powerful assault!

It seemed that the castle's defenses were no match for the sheer force of the Dragon's wrath.

This attack lasted for five more minutes, and as the final layer of the barrier shattered in a dazzling display of light and sound, Mennena seized the opportunity to weave her own enchantments, cloaking herself in a veil of invisibility that rendered her unseen by mortal eyes.

With each activation of her spell, she crossed through all the mirrors and entered the castle in the blink of an eye!

Within the hallowed halls of the castle, Mennena's Spiritual Sense was activated, and soon, she was guided by an unseen force and created a spiritual form!

Mennena's Spiritual Form then navigated the corridors with the deftness of a seasoned thief, and it didn't take that long before he finally found the location of the Golden Key!

"You're mine!"
