Somewhere in the oceans of the New World, on board a certain ship—

Chu… chu…. Slrrppp… mmwwaahh…

"Aaahnn… Captain… ahhnnn… n-not so rough… hhnnn… hnn…"

Within the closed doors of the Captain's cabin, the sensual moans of multiple women, the erotic sounds of licking and kissing, the wet sounds of flesh slapping against flesh seemed to have been echoing for the past few hours…

"Aaahn… aahhhn… Captain Zechs… please have mercy… I can't take it anymore ahhhnn…" A woman, with no clothes covering her beautiful and trained body, moaned erotically, digging her nails into the muscular back of the naked man while she felt intense pleasure from being railed in her most intimate part with his massive cock.

Her body trembled atop him as she hugged him tightly, burying her beautiful face into his chest, which was slick with sweat and the remnants of hours of relentless passion, her walls clenching desperately around his thick shaft as he drove into her with unyielding force, with a grin.

There were five other women lying scattered across the cabin floor and bed, their beautiful, naked forms limp and unconscious, chests rising and falling in exhausted breaths, pussies and asses leaking thick trails of his white cum from the marathon of ecstasy that had claimed them one by one.

"Damnn… guuhhhh…" Zechs grunted, his muscular frame glistening under the dim light filtering through the curtains. He briefly looked at the rising sun before picking up his speed as his hips snapped forward in a final series of brutal thrusts, stretching her to her limits.

Plap! Plap! Plap!

"Nngh… take it… all of it," he growled low, his voice rough from the night's exertions.

Her eyes widened, body arching as the overwhelming pleasure crashed over her. "C-Captain… I'm… I'm cumming… aaaahhhhh~!"

Spurt! Spurt! Spurt!

With a deep groan, Zechs buried himself to the hilt, his cock pulsing violently as hot, thick ropes of cum flooded her pussy, filling her completely until it overflowed, mixing with her squirting juices in a messy cascade.

Squelch~ Squelch~

Her screams dissolved into shuddering whimpers, her body convulsing in orgasm before going slack, eyes rolling back as consciousness slipped away, joining the other five in blissful oblivion.

Zechs pulled out with a wet pop, a satisfied sigh escaping his lips as he surveyed the scene, six women utterly spent, their bodies marked by his dominance, the air heavy with the scent of sex and satisfaction.

He let them rest where they lay, stepping away to light a cigarette, the flame flickering as he inhaled deeply, exhaling a plume of smoke, with a sigh, "The entire night spent in sex… as you'd expect from a lustful man like me…"

Shrugging, the man grabbed the bottle of rum from the side table. He took a long swig, the burn soothing his throat, before heading to the small basin to draw a bath, sinking into the warm water to wash away the night's indulgences.

And while exhaling the smoke, he also decided to check out the System Panel of his Underworld's Growth System.

[Available Bloodline Points: 6]

[Available Attribute Points: 720]

————————————

"720 Attribute Points and 6 Bloodline Points. It's not so bad, I guess," Zechs murmured as he studied the numbers displayed on the System panel under the Available Bloodline Points and Available Attribute Points counters. He gave a small nod, feeling fairly satisfied with the result.

Women sleeping in his cabin had originally been cargo on a slave ship, destined to be sold at an auction. Each of them was quite beautiful. Zechs had taken them during his raid on the vessel while searching for something rare or valuable. Although he hadn't found anything extraordinary like a Devil Fruit, he had ended up with these six women instead.

There were other slaves as well, but Zechs paid them no attention. Only these six women had drawn his interest because of their beauty. As for the others, the rough-looking men and the rest, he had left them behind on the ship. Whether they lived or died, or whatever fate awaited them, had nothing to do with him.

He was not a benevolent man. He was a pirate who had spent years sailing the seas. During that time, he had seen and done all kinds of things. Mercy for strangers was no longer something he carried lightly.

Anyway, these six women, after being rescued by him, desired to express their gratitude to him, their savior, by offering their bodies to him.

As the hero saving the damsels in distress, accepting the damsel's gratitude and fucking them to the point of leaving them unconscious is only natural, right? It's not as though he was forcing himself upon them; it had been their own choice.

All he had done was guide them toward that decision by relying on his racial traits, his Charm, persuasion, and natural pheromones.

Those women had already held a favorable impression of him. Under the influence of his charm, his persuasive manner, and the subtle effect of his pheromones, their emotions gradually intensified as their bodies felt hot, and they ultimately chose to warm his bed of their own accord.

They didn't seem to mind that they were all sharing him at the same time. Nor did it matter to them that some had families waiting back home, a lover, a husband, or even children. In that moment, their focus was solely on pleasing him, and they willingly devoted themselves to him together in a one vs six orgy.

'Fufu… I really am a scoundrel, aren't I?' he thought.

The thought didn't trouble him at all. After more than five years as a pirate and a life where he spent time with a different set of women almost every week, why would something like that bother him now?

Anyway, after spending the night filled with lust with the six women, he had accumulated a total of 720 Attribute Points, and the System also awarded him with 6 Bloodline points.

Bloodline Points and Attribute Points are points Zechs earns whenever he engages in a sexual encounter.

As these two have different names… naturally, they have different roles.

Attribute points are for improving his physical attributes. They can be allocated to various physical attributes available on the panel, like Strength, Agility, Endurance, Resilience, and Vitality.

The number of Attribute points gained from each encounter is not fixed. Different women yield different amounts, and strength plays a key role; the stronger the woman, the greater the amount of attribute points obtained.

Going by this piece of information, the most obvious thing is to fuck the strongest women on the seas regardless of their physical appearance, but Zechs has his own standards. Regardless of the points involved, he has no interest in women he does not find physically attractive.

People often talk about looking for inner beauty, but Zechs had no interest in that. It's not as though he is looking for a marriage and desires to settle down… Inner beauty only matters in that scenario; otherwise, physical beauty matters more.

Afterall, he was here to enjoy himself, and to him, enjoyment meant one thing: the women had to be attractive.

Otherwise, where was the fun in that?

Setting the Attribute Points aside, there were also Bloodline Points to consider.

As the name suggests, Bloodline Points are related to the Bloodline that he has.

Unlike Attribute Points, Bloodline Points were more restrictive. The system did not award them for every ejaculation. At most, Zechs could obtain only one Bloodline Point from one woman each day. No matter how many times he ejaculates inside the same woman or how many different women he is fucking at the same time, he can earn only one bloodline point per day per woman.

Earning Bloodline Points was difficult, but they were extremely important. They were required to upgrade his Incubus bloodline and unlock new racial traits.

Each time his bloodline levelled up, a new racial ability awakened. So far, he had gained traits such as Charm, Endless Virility, Pheromone Secretion, Physique Alteration, Persuasion, Life Drain, Attachment, and Obsession. And as his bloodline continued to evolve, he expected even more abilities to emerge.

'Hmm… but if the Incubus bloodline reaches level 50 or 60… are there even that many racial traits for an Incubus?'

The thought left him slightly puzzled, but there was no way to know the answer. In the end, he simply shrugged.

'Whatever, I'll find out eventually… so, let's just allocate the points I have available at the moment.'

With that, he invested the Bloodline Points into his bloodline and distributed the Attribute Points across his physical stats.

The moment he finished allocating the points, a warm current surged through Zechs' body, nourishing every part of him. The sensation spread from head to toe, briefly making his muscles tense before gradually settling down.

Immediately, he looked at the System Panel again.

Zechs looked at the System panel and gave a command.

"Run a strength assessment."

The System processed multiple parameters before displaying its conclusion:

[Elite Rear Admiral of Marine Headquarters]

Zechs wasn't a Marine, but the System evaluated strength using Marine ranking standards.

'Well… It's probably because the structure is clear and systematic,' he thought.

However, there was an issue with the assessment.

"System, reassess my strength. This time, include all three types of Haki, Swordsmanship, and Physical Skills."

The System's default evaluation did not account for Haki, Swordsmanship, and Physical Skills unless specifically instructed.

Haki, Swordsmanship, and Physical Skills are always treated differently, in the same manner as a Devil Fruit ability. Possessing a Devil Fruit didn't necessarily define a person's overall strength, which is why the System generally bases its judgment only on the five physical attributes.

And according to that assessment, Zechs is at the level of an elite Rear Admiral of Marine HQ.

But was that his true strength? Obviously not.

After several years at sea, Zechs had acquired a variety of additional skills. He had learned techniques such as Shave and Moonwalk from the Marine Six Styles, abilities that were both practical and highly useful in combat. Swordsmanship was something he had trained in even before setting sail, and he had also devoted considerable effort to developing his Haki. After all, in this world, survival without Haki was nearly impossible.

That said, he was not yet a master of all three types.

His Observation Haki was relatively well developed, but his Armament Haki was still in its early stages. Only recently had he made enough progress to coat his fists or sword with it.

Even so, considering that Haki mastery was typically associated with Vice Admirals, Zechs was confident that his overall strength had already surpassed that of a Marine Headquarters Rear Admiral.

And once the System took his Haki and combat skills into account, his overall evaluation would undoubtedly rise.

"After all… I carry a bounty of 600 million Berries. That kind of bounty isn't given without reason."

Just as he expected, when the System reassessed him, this time factoring in his Haki, swordsmanship, and physical abilities, the result changed.

[Newly Promoted Vice Admiral of Marine Headquarters]

'With this… I'm one step closer to becoming the Harem King,' Zechs thought, a faint, pleased smile forming on his lips.

As for why he wanted to become the Harem King? Well… he didn't really have anything better to do. Besides, the System he had awakened after transmigrating into this world seems to revolve entirely around Lust.

Indeed, as many might have already guessed, Zechs… or Zechs Asmodeus, is not a being from this world.

'Ahh… but considering the naming customs of this world, it's probably better to go with Asmodeus Zechs… Hmm… maybe I should add a 'D' as well… but forget it. That would just be troublesome… and I'm not really a 'D' anyway,' he thought, shaking his head as he slowly exhaled a stream of smoke.

Although 'D' was something that could easily be added, as it's not something one necessarily inherits, Zechs decided not to add it to his name, as it might cause him trouble that he isn't interested in dealing with.

In any case, Asmodeus Zechs, the name he had chosen for himself, was not someone born in this world. He was a transmigrator who had suddenly found himself in a world of pirates, marines, and endless seas.

Like most transmigrators, Zechs had grown up as an orphan. It's almost a curse, and he wasn't spared from it either.

He would have liked to have parents in this life… since he didn't have decent parents in his previous one… It's really a pity.

In his early years, he survived by relying on himself and the occasional kindness of others.

Fortunately, the village he grew up in had a small school of swordsmanship, which allowed him to learn some swordsmanship skills that he could also use to hunt down wild animals and live as a hunter. Without that, his situation might have been far more difficult.

It's just that while he had his livelihood secured, and he was slowly gaining the strength to protect himself, he still didn't know what he wanted to do in this world. He had no clear goal, no real motivation.

People often say a man should have ambitions as lofty as Mount Tai. But Zechs, who had grown up in the modern world on Earth, had felt burned out…

At that point, he simply didn't know what he wanted from this new life… he was purposeless.

Of course, he could have gone out to sea and become a pirate, a marine, a bounty hunter, a mercenary, an adventurer; there were endless possibilities in this vast new world that he used to read about a lot in the stories.

The idea of setting out on grand adventures, creating his own legend that would inspire future generations, was certainly exciting. But his practical nature had kept him grounded for a long time.

Being a pirate or a sailor wasn't nearly as exciting as manga and anime made it seem, especially for someone like him who was used to having a phone, a laptop, the internet, and online food delivery with him all the time.

How was he supposed to endure a life without all that? He was already having a lot of difficulty without all that.

In his previous life, he had been a hikikomori who preferred the safety of his room. Even stepping outside to learn swordsmanship had already felt like pushing his limits.

So the thought of adventuring wasn't nearly as exciting as it seemed.

Moreover, the sea was also filled with all kinds of dangers. There were powerful enemies, unpredictable weather, and the exhausting monotony of life aboard a ship, endless days surrounded by sweat, salt, and grime.

Did people really think sailing across the ocean was easy? Especially in this era, when there were no cruises, powerful ships, or modern navigation systems, and ships relied entirely on the wind as well as sea currents to move their sails. Traveling from one island to another could take weeks if not months. And the weather was so unpredictable that even a fleet led by a great pirate like Shiki the Golden Lion could be wiped out in an instant.

And there were other dangers as well. What if the Marines captured him and threw him into prison? What if pirates attacked and killed him? Worse, given his above-average appearance, he might even be captured and kept as a slave by a fat, ugly bitch like Alvida (before she ate the Devil Fruit).

Zechs didn't want to be Coby… who could only live a life of misery.

There was no guarantee that a figure like Monkey D. Luffy would come one day to save him. Even if someone like him may come and save him… why would he want to endure those many years in misery? He ain't no masochist, you know…

This was not a world of laws and rights. It was a brutal world where strength decided everything, a place where only the strongest had the power to speak.

Not to mention, he wasn't Monkey D. Luffy, blessed with a protagonist's fortune.

He didn't have a grandfather who was a Marine hero willing to overlook his crimes, even after incidents like the destruction of Enies Lobby and the burning of the World Government's flag. He didn't have a father who led the Revolutionary Army and could appear at a critical moment to save him from someone like Smoker in Logue town.

He didn't have a brother like Portgas D. Ace, a division commander of the Whitebeard Pirates. Nor did he have another brother who served as the Chief of Staff of the Revolutionary Army.

He also lacked a figure like Shanks, a Yonko who would protect him, give him the legendary Straw Hat, and indirectly place one of the world's most powerful Devil Fruits in his hands. And there was certainly no former First Mate of the Pirate King to personally train him in Haki.

He was just an ordinary man from an ordinary village, with ordinary deceased parents, living an ordinary life

The only thing even slightly noteworthy about him was his somewhat above-average appearance, enough to attract the attention of a few women in his village.

And that was all.

For several years, he hesitated, feeling that risking his life like that simply wasn't worth it. He wasn't the protagonist Monkey D. Luffy… what did it matter whether he didn't sail and continued to live in his village? Instead of venturing out to sea, wasn't it better to continue to live a quiet, slow life as an ordinary villager?

But then one particular day, to Zechs' surprise, everything changed.

It was the day he had heard a mechanical sound in his mind, [Ding! The Host has awakened the Underworld Growth System.]
