Desolate Island.
Lucien remained silent, gazing at the magnificent form before him: his upgraded Siren Martial Spirit.
Hovering above the ground was a colossal figure, easily tens of meters tall. Its upper body resembled that of an ethereal human woman, while the lower half extended into a massive fish tail covered in shimmering pink scales.
There was no doubt—this was a gigantic mermaid!
But why had Lucien inherited a Siren spirit instead of the Swan spirit traditionally passed down through the Heaven Dou Imperial Family?
The reason lay with his mother.
Although a princess of the Heaven Dou Empire, she had not inherited the Swan Martial Spirit like the rest of her lineage. Instead, her spirit was something far rarer: a Siren.
Thus, as her son, it was only natural for Lucien to inherit her spirit rather than the martial spirit of his Star Luo father.
Originally, the Siren spirit would manifest at a normal, human-like size—nothing overwhelming like this. But after using the Martial Spirit Upgrade Card, everything changed.
Now... it had mutated.
Lucien narrowed his eyes as he studied the awe-inspiring Siren before him.
She had long, cascading pink hair, styled in an elegant, ancient fairy-like bun. Her head was adorned with taiyaki-shaped hairpins, her earlobes sparkled with shell-shaped earrings, and her ocean-blue eyes gleamed with serene wisdom. Her beauty was otherworldly, an enchanting sight that seemed divine and untouchable.
Her upper body was gracefully curved, of almost unreal proportions, while the lower half flowed into a pale-pink fishtail that shimmered in the sunlight like mother-of-pearl.
Lucien's lips parted as he recognized her silhouette—a familiar image from another world.
"Princess Shirahoshi... the Mermaid Princess," he murmured softly.
In One Piece, Shirahoshi was a key character—a mermaid princess who was also Poseidon, capable of commanding all the mighty Sea Kings across the oceans.
Now, Lucien finally understood the deeper meaning behind the system's cryptic message: his Martial Spirit had the chance to inherit abilities from other worlds.
After evolving, his Siren Spirit had taken the form of Princess Shirahoshi. And with it came her incomparable ability: to control not only the Sea Kings—but all sea creatures.
The violent outburst of marine soul beasts earlier had been triggered by the unique pulse of Poseidon's energy released during the initial summoning of his newly evolved spirit. The beasts, sensing a divine presence, had mistaken Lucien's awakening for the arrival of the Sea God himself. Fortunately, such chaos wouldn't recur once his spirit stabilized.
"The Martial Spirit Upgrade Card from the system is insanely powerful," Lucien whispered, his gaze fixed on the towering Siren. Even without considering her sea-dominating abilities, her sheer size spoke for itself. With tens of meters in height, the destructive force she could unleash was unimaginable.
"But… what about my other Martial Spirit?"
With that thought, the massive Mermaid Princess dissolved into a glimmering light.
In her place, another colossal figure began to form.
"RROOOAAAR!!!"
A fierce, earth-shaking roar rang out across the surrounding waters!
A colossal white tiger soared through the sky on outstretched wings. Its fur sparkled in crystalline white, starkly contrasted with deep-black stripes. Its blood-red eyes burned with ominous power, radiating a chilling aura of death and domination.
Its presence was terrifying.
Lucien stared wide-eyed at the towering beast. "It… grew wings? And… its body—"
The once proud King of the Land had evolved into something far greater: a Nether White Tiger, capable of flying.
This wasn't just a transformation. It was transcendence.
Clenching his fists with excitement, he exclaimed, "This is insane!"
Quickly, he summoned the system panel mentally:

Lucien's eyes lit up. "Both spirits evolved beyond their original forms… and both are way stronger than before!"
He could barely wait to test their potential.
Especially... his Siren Spirit's power to control sea soul beasts. Could he even force one to willingly offer itself as a sacrifice?
"Only one way to find out."
---
The ocean breeze brushed his face as Lucien walked barefoot in the sand, letting the waves lap at his ankles.
The moment his skin touched the sea, he felt an odd comfort—like he had returned home.
This was one of Mermaid Princess's new abilities: Ocean Sense.
With his eyes closed, his consciousness instantly expanded, connecting with the vast ocean—feeling every current, every motion… every lifeform. His perception extended like a god's—a 360-degree omniscient vision beneath the sea spanning thousands of kilometers.
He gasped.
"Terrifying…"
But fitting. His spirit was essentially the Sovereign of the Sea. This kind of omniscient marine awareness made perfect sense.
Soon, he detected hundreds of soul beasts, mostly between 100 and 1,000 years old—perfect for a first hunt.
His gaze locked onto a 1,000-year-old shark.
"You. Come."
Without hesitation, the shark swam toward the shore, beaching itself at his feet.
Lucien stared at the enormous creature, watching it struggle internally—its mind resisting, while its body obeyed.
He shivered.
This power... Is this what it means to be a Sea God?
He whispered, "Martial Spirit… Release."
Behind him, the colossal Mermaid Princess reappeared, ethereal and divine. She lifted a delicate hand like jade—
BOOM!
The shark was crushed instantly. A purple soul ring floated upward.
Lucien watched solemnly. The ocean must obey—but its souls still resisted. True voluntary sacrifice was still impossible. Otherwise, his first soul ring would have exceeded 10,000 years instead of a mere thousand.
"Come."
The purple ring drifted toward him, merging with his Mermaid Princess Martial Spirit.
Instantly, a surge of energy flooded his body. Strength surged through him. His senses sharpened. His physique rapidly strengthened under the fierce nourishment of the soul ring.
Normally, a first ring for any soul master would only be a 100-year yellow ring. But with Lucien's system and upgraded spirits, his physique far surpassed the norm.
In fact, he estimated his body was now on par with a Rank 30 or 40 Soul Master!
And as everyone knew, the key to absorbing stronger soul rings wasn't just soul power—it was whether your body could withstand it.
So… absorbing a thousand-year ring as his first ring? Not even a problem.
Closing his eyes, he felt inward.
"Let's see what ability I got…"
Moments later, he opened his eyes wide.
His right arm glowed golden.
"Is this…!"
Golden energy wrapped around his arm like an indestructible armor.
Armament Haki!
From the world of One Piece, Haki was a mysterious force, divided into three types:
Observation Haki
Armament Haki
Conqueror's Haki—the supreme form!
And now... Lucien had just unlocked one of them.
