The Strongest Lunarian in One Piece

Three Days Later

Totto Land Kingdom

Deep beneath the Totto Land Sea, in an enormous underground laboratory…

"El-sama!"

Led by Ryan, the scientists saluted El and his entourage. Among them were Dr. Kureha—who had spent the past two years mastering lineage factor technology after its discovery by Dr. Vegapunk and others—and several elderly, bespectacled female scholars. These scholars, once top experts in their fields, had been coerced—partly through force, partly through persuasion—into joining the project.

After a series of thorough checks using specialized equipment to analyze the mothers and their unborn children, the scientists confirmed the parameters and prepared for the next phase of the lineage factor modification process.

The procedure itself was led by Dr. Kureha, who had personally overseen the technology's development, supported by her team of female scholars and doctors.

After all, these were El's women. He spared neither expense nor caution when it came to their safety.

"Mamamamama! Please take care of everything from here!" Linlin exclaimed, brimming with excitement. She couldn't wait to see the potential her children would gain after the modifications.

Though both she and El were natural-born "monsters," not every child they bore could reach such heights. With lineage factor technology, however, they could ensure optimal conditions for their offspring.

"This is our duty," Ryan replied with a smile.

Never one for formalities, Dr. Kureha gestured for the group to follow her. "Kukurururu, come with me!"

She and her assistants led Linlin, Lily, Gerd, and the other women—including Abyss, wife of Afar the Fire Calamity—into the laboratory.

Meanwhile, El and Afar stayed outside, conversing with Dr. Vegapunk and his team.

"Tsk, tsk, Vegapunk! Your head just keeps getting bigger, doesn't it?" Afar commented, eyeing the young scientist's disproportionately large head with mingled curiosity and amazement.

"Indeed! It's a testament to knowledge," Vegapunk replied with a quirky laugh, patting his enormous, bulbous head.

Despite being only twenty-one years old, Vegapunk already had the look of an eccentric genius. His head, larger than his entire body, resembled a glowing lightbulb, and his demeanor carried the weight of someone far older.

"In history, there have been others who ate the Brain-Brain Fruit," remarked Dr. Tsukimi, a white-haired senior scientist with a calm smile. "Some of them became renowned scholars, but none of their heads grew like yours. Perhaps their knowledge capacity was limited."

Dr. Tsukimi greatly admired Vegapunk's talent. Although he had once been Vegapunk's teacher, the young scientist had already surpassed him in many respects.

Ryan—another of Dr. Tsukimi's students and an exceptional scientist with the powers of the Munch-Munch Fruit—was also incredibly gifted. However, in comparison to Vegapunk's unparalleled genius, even Ryan fell short.

"It's true," Tsukimi continued. "Your mastery of knowledge is exceptional, Vegapunk, but the sheer growth of your brain still fascinates me."

Vegapunk chuckled modestly, brushing off the praise. "There's always more to learn, and with more knowledge come more possibilities."

El observed their conversation with a smile, confident that the fruits of their research would lead to unparalleled advancements—not only for his children but for the strength and future of the Totto Land Kingdom.

"By the way, how is the Pacifista Project progressing?" El asked, as though recalling something. "Roughly how long will it take to complete?"

"Ah, El-sama, please follow us…" Ryan said with a mischievous grin. "I promise you won't be disappointed!"

"Oh?" El raised an eyebrow, glancing at Vegapunk and Dr. Tsukimi. Their confident expressions suggested they had good news.

With Dr. Kureha and her team overseeing the lineage factor modification procedures, El, Ryan, Afar, Vegapunk, and the others proceeded down a wide corridor. Passing through multiple checkpoints, they arrived at a massive laboratory.

Rows of towering glass containers, each several meters high, lined the room, all filled with green cultivation fluid. Inside were tall, expressionless beings whose silhouettes closely resembled Cyril Oka—the "Thunder Calamity"—famed for his scarred visage after a fateful battle with Iron Claw Hark.

"Every time I see these guys, it feels unbelievable," Afar remarked, his tone both awed and composed. As one of the Fallen Angel Pirates' core officers, he was privy to these secrets.

Two years earlier, after the scientific team officially discovered the lineage factor, El had ordered the launch of the Pacifista Project. With Cyril Oka's consent, his robust Buccaneers body was used as a sample to extract his lineage factor, cultivating numerous clones. The goal was to transform these clones into true war machines equipped with cutting-edge laser systems.

However, what truly caught their attention wasn't inside the containers. Outside, connected to a network of massive and intricate circuitry, stood a tall figure undergoing "charging."

It looked identical to the clones in the cultivation fluid but wore a black combat suit. Standing motionless, it exuded a suffocating sense of menace.

"This is…" Afar's pupils contracted.

"Oh, has it been fully completed?" El asked, raising an eyebrow with interest.

"Yes, this is the first prototype—PX-1," Ryan said proudly, his grin widening. "Thanks to enhancements from the Munch-Munch Fruit, its body is tougher than steel. It follows orders precisely and can autonomously identify hostile targets based on pre-loaded data.

"However," Ryan continued, "it hasn't undergone live combat trials yet. Its performance and any potential flaws must be tested further and optimized."

"We've unanimously agreed," Dr. Vegapunk interjected, his brilliance evident in his voice, "that the next step is to deploy it secretly in real battlefield conditions to gather essential data."

"I have no objections," El said with a smile, approaching the fully upgraded Pacifista. "Since it's modeled after Cyril Oka of the Buccaneers Tribe, let him oversee its deployment. The Pacifista project exists largely thanks to his contributions."

Not everyone was willing to donate their genes to create clones-turned-war machines. As the leader, El hadn't forced Cyril Oka's hand; initially, he planned to use other Bakanea tribe members. But Vegapunk and the scientists insisted on Oka, given his extraordinary strength. Convincing him wasn't easy—it required emotional appeals, lucrative incentives, and talk of the greater good. In the end, they even promised to restore his disfigured face and remove his scars, finally securing his agreement.
