System at One End and Harem at the Other End

As they left the Adventurers Guild, David\'s mind was already occupied with thoughts of preparation. He knew the dangers that awaited him in the high-ranking dungeon, and he didn\'t want to venture into it unprepared.

As they continued moving forward, David\'s mind wandered, drawing upon his countless years of reading stories from various genres and platforms. He understood the patterns that often unfolded in such dungeons.

There would invariably be a powerful monster lurking within, carefully crafted by the author to heighten the plot\'s tension. Despite being the main character of his own story, David knew that safety wasn\'t guaranteed.

The author would find a way to save him, but there might be sacrifices along the way. With this realization, a sense of urgency filled his thoughts.

He understood that even the strongest individuals could fall victim to a single mistake, and he was determined to avoid such a fate.

Walking along the streets toward his inn, David\'s eyes caught sight of a weapon shop. It was the perfect opportunity to acquire an additional sword for tomorrow\'s expedition. With a sense of purpose, he steered their path toward the shop.

Amidst the bustling sounds of the street, David turned to Luna, his tone firm and authoritative.

"Luna, you will not come with me tomorrow," he stated, his voice carrying a sense of responsibility.

Luna, with her adorable cat-like features, looked up at David, her eyes brimming with sympathy. She desperately wanted to accompany him on his journey.

"But Master, even I want to come, Nya," she pleaded, her voice filled with longing.

David\'s expression remained stern as he held his ground.

"No, you will stay here," he insisted.

He knew the risks involved and wanted to ensure Luna\'s safety. He couldn\'t afford any distractions or additional burdens on his mission.

Disappointment flashed across Luna\'s face, but she ultimately conceded to David\'s decision.

"Alright, Master," she replied with a hint of sadness, accepting his authority.

David softened his tone, wanting to lift Luna\'s spirits.

"If you do as I say and become stronger while I\'m away, I promise to take you to a different city when I return," he offered, hoping to motivate her.

Luna\'s eyes sparkled with excitement as she leaped with joy.

"Nyahoooo!" 

She exclaimed, her sadness quickly replaced by the anticipation of future adventures.

With their conversation settled, David entered the weapon shop, ready to select a suitable sword for the challenges that awaited him in the formidable dungeon.

Inside the weapon shop, David scanned the assortment of swords displayed on the walls. His gaze settled on a simple, yet sturdy, sword. It exuded a sense of reliability, and David believed it would serve him well in the upcoming dungeon.

"I\'ll take this one," he informed the shopkeeper, his voice filled with conviction. He exchanged the appropriate amount of gold, securing the sword at his side.

Leaving the shop, sword now in hand, David made his way back to the inn. The bustling streets slowly faded away as he entered the familiar haven that had been his temporary home. The innkeeper greeted him warmly, recognizing him as a regular customer.

Next day, David bid Luna farewell and set off from the town towards the direction of the dungeon that had recently opened across the border. The weight of the key nestled in his pocket reminded him of his plan to return to Earth momentarily.

He needed to check on things back home, as he had already spent several days in this captivating fantasy world. The fear of his prolonged absence being noticed on Earth gnawed at his mind, prompting him to venture alone and leave Luna behind.

Previously, before receiving the system, disappearing for days wouldn\'t have raised any eyebrows. David led a solitary existence, confined to his tiny apartment without any meaningful connections or obligations.

But ever since acquiring the system, everything had changed. He had forged friendships, found himself surrounded by a harem, and even landed a job in the modeling industry. Ignoring calls from his agency now could have unforeseen consequences, and he couldn\'t risk losing the life he had built.

As David walked towards the dungeon, his thoughts raced with the possibilities and dangers that lay ahead. He knew from countless stories he had read that dungeons like this often housed powerful monsters, carefully crafted by authors to heighten tension and excitement.

An hour passed as David ventured further, finally arriving at the entrance of the dungeon. It was a desolate place, guarded by a few security personnel who were stationed there to prevent unsuspecting individuals from meeting their demise.

The bodies of those who had entered were found lifeless, their vitality drained by an unseen force. David absorbed the information the vice guild master had shared the previous day.

The notion that those who perished in the dungeon became nourishment for its very existence sent a shiver down his spine. 

"Hello I have come here for S-Rank assessment, and here is my permit" David spoke

Approaching one of the guards, David presented his permit for the S-rank assessment. The guard\'s eyes widened with admiration, acknowledging the bravery and determination required to face such a formidable challenge alone.

"Alright, sir," the guard responded, a mix of respect and curiosity in his voice.

David\'s arrival to clear this high-ranking dungeon left an indelible impression on the guard, who couldn\'t help but wonder about the adventurer\'s skills and what awaited him within the dungeon\'s treacherous depths.

Before David could enter a sudden system notification popped up in front of his eyes with a new quest.

╚══════════════════════════════════════════════╝

After reading the quest, David stepped into the dungeon, the air grew dense and the temperature dropped. The walls were rough and jagged, covered in ancient moss and signs of erosion. The ceiling stretched high above him, lost in darkness, while narrow pathways wound through the labyrinthine corridors. Water dripped from the stalactites, creating a constant echoing rhythm.

"Fwiss"

In the dimly lit surroundings, David ignited a flame in the palm of his hand, casting flickering shadows on the uneven floor.

The eerie silence was interrupted only by the fluttering of bat wings and their faint screeches.

With each step, David\'s anticipation grew, fueled by the unknown that awaited him. The absence of any encounters besides the bats heightened his excitement, but he remained vigilant, ready to face whatever challenges lay ahead.

After effortlessly dispatching the bats that swooped down upon him in the dungeon, David made his way towards the entrance to the boss chamber. The bats, with their remarkable agility and sonic attacks, would have posed a significant challenge to anyone below A rank. However, David\'s formidable strength and skill allowed him to eliminate them without breaking a sweat.

As David approached the entrance, a mysterious and alluring laughter resonated through the air. Intrigued by the source of the laughter, he cautiously opened the door. What he discovered inside sent a shiver down his spine.

Before him stood a peculiar woman, her presence both captivating and unsettling. She was in the midst of draining the life force from a fallen adventurer who had bravely ventured into the dungeon before him. The adventurer lay motionless, his vitality cruelly consumed by the woman.

Peering closer, David noticed the woman\'s bat-like wings, adding to her otherworldly allure. Her attire, barely covering her posterior, accentuated her seductive yet dangerous nature.

"God\'s Eyes,"

David murmured under his breath, driven by the need to uncover the creature\'s true identity and understand her unique traits. Instantly, a mysterious status window materialized above the monster\'s head, offering insights into her capabilities and characteristics.

╚══════════════════════════════════════════╝

As David read through the message about the monster, his eyes widened in realization. It was a Succubus, a creature he had only encountered in stories and now stood before him in the flesh. This was his first time facing such a formidable opponent, especially considering she was an S rank monster.

He observed the Succubus as she finished draining the life force of her prey, leaving them lifeless on the ground. With a sinister smile on her face, she turned her attention towards David, her eyes filled with hunger.

"Ke Ke ke keke kekekeke"

Emitting an eerie laughter, she taunted him, proclaiming another fool had arrived to be her next meal. Slowly and menacingly, she advanced toward David, ready to strike.

As the Succubus approached, David\'s attention was momentarily diverted by another system quest that materialized before his eyes. With a mixture of surprise and frustration, he read through the quest details, muttering under his breath,

"What the fuck is this?"

The quest presented a daunting challenge for him which he had never thought would appear.
