Stockholm

"Young Master, it's so cold."

Charloss, dressed in a bikini, shivered violently from the cold. Even the Special Necklace around her neck had accumulated a layer of snow.

Anna beside her was no better.

Anna was also wearing a Special Necklace, though she had put it on herself.

Because she had discovered that Young Master seemed to have some kind of special fetish.

Nojiko and Makino watched Anna and Charloss from the side, their pretty faces flushed red.

Because according to Lin Yu, they would be next to undergo this Willpower Training.

Lin Yu's training method was actually one the Russians had used in his previous life to train recruits. It could strengthen a recruit's willpower.

So-called willpower was actually Mental Power, one of the three physical attributes.

The higher one's Mental Power, the stronger their control over Devil Fruits and Haki, and the easier it was to unleash greater strength.

Likewise, the easier it was to awaken a Devil Fruit ability.

Both Anna and Charloss had eaten Zoan-type Devil Fruits. Without sufficiently high willpower—that was, Mental Power—they could easily become Jailer Beasts controlled by their Devil Fruits after awakening them.

Naturally, that was not what Lin Yu wanted.

Just like Lucci and Kaku, perfectly awakening their powers and gaining the Zoan-type Flame Cloud was the goal he had set for Anna and Charloss.

Of course, he had read about this method online. Whether it worked or was even real, he had no idea.

It was rare to visit a Winter Island. There was no harm in trying.

In any case, he thought it was quite good.

"Alright, switch."

Lin Yu checked the time and gave the order.

"Yay!"

Anna and Charloss cheered, running over to Lin Yu and each hugging one of his arms.

"Such good girls."

Lin Yu chuckled, pulled them onto his lap, wrapped them tightly in a blanket, then used the fur coat draped over himself to cover both himself and the two women.

Wrapped up warmly, Anna and Charloss leaned against Lin Yu's chest with blissful expressions. Their gazes at him were practically dripping with tenderness.

As long as they carried out Young Master's orders, they would receive his thoughtful care.

Thus, Anna and Charloss did their utmost to fulfill any order Lin Yu gave them.

Even when some of Lin Yu's demands were extremely perverse, they never resisted. They even seemed to enjoy them.

Because that meant they could once again receive Young Master's praise and care.

Seeing their expressions, Lin Yu smiled.

When escape was impossible, after handing out two slaps and then offering a sweet date, that date would seem exceptionally sweet.

Based on Stockholm theory combined with the knowledge from Authority Training, this was Lin Yu's perfect method for training Anna and Charloss.

With the Telepathic Connection talent added to the mix, it was impossible for Anna and Charloss not to fall for him.

Of course, this method worked equally well on Nojiko, Makino, and the others.

Elsewhere.

"Pervert!"

Nojiko and Makino glared at Lin Yu, blushing and gritting their teeth as they began a two-person game of Beach Volleyball in bikinis, following Anna and Charloss's example.

"Tsk, tsk, tsk. He really knows how to have fun."

Doctorine Kureha watched Lin Yu's antics from inside the castle, clicking her tongue in amazement.

Then she glanced at Kaya, who was diligently studying, and immediately beamed.

Kaya was beautiful and exceptionally smart. She studied diligently and attentively, knew how to speak and comfort people, and had a gentle temperament.

If she could have beaten Lin Yu, she would have wanted to snatch Kaya away and make her her own granddaughter.

Two days passed like this.

Kaya then boarded the ship with Doctorine Kureha's medical notes and the Rumble Ball formula.

After returning to the God Slave and setting sail.

Lin Yu finally learned from Reiju about the Munch-Munch Fruit Pie, leaving him both amused and exasperated.

As long as a pirate or Marine was killed by an officially recruited member recognized by the system, Lin Yu would obtain their treasure, Bounty, or Devil Fruit.

Lin Yu had known that long ago.

Just like at Whiskey Peak, when Anna and the others finished off enemies, Lin Yu would receive notifications as well.

What he had not expected was that Wapol would actually set his sights on the God Slave.

"If it can really synthesize Memory Metal, then Battle Suits can be mass-produced."

When Reiju heard Lin Yu say that the Munch-Munch Fruit could synthesize Memory Metal, her eyes lit up. She immediately came to the same conclusion as Lin Yu.

Although Lin Yu had obtained several Battle Suits from her father Gage, there were only a few. There were not even enough for everyone currently aboard the God Slave.

If it was confirmed that the Munch-Munch Fruit could produce Memory Metal, then in the future, everyone could basically have a Battle Suit.

Although those without Lineage Factor modifications could not bring out a Battle Suit's full potential.

Its flight and defensive capabilities were still quite impressive.

"You had the same idea as me." Pinching Reiju's delicate nose, Lin Yu smiled.

Reiju lightly bit the finger that was pinching her nose and looked at him with a smile. "Who do you want to have eat this Devil Fruit?"

As someone with the Poison Powder ability, Reiju did not want to eat a Devil Fruit. It would cause her to lose the ability to swim.

Besides, having an entire ship full of Devil Fruit users could easily lead to accidents.

Of course, if they encountered an extremely rare Devil Fruit, she would naturally not pass it up.

"I don't have a candidate for now."

"Nojiko and Kaya probably wouldn't be willing to eat this Devil Fruit."

Lin Yu shook his head and said with certainty.

As delicate, gorgeous women, Nojiko and Kaya definitely would not want to eat the Munch-Munch Fruit.

Besides, Lin Yu did not want them to eat it either.

To mass-produce Wapol Metal, they would have to continuously eat metal. That was too cruel for Nojiko and the others.

"Perhaps we could let an animal eat it. And Vegapunk has already developed technology that allows objects to eat Devil Fruits."

"If a machine could eat it, that would be the optimal solution."

Reiju had guessed Lin Yu's concerns and voiced her opinion.

"Mm, that's a good idea."

Lin Yu strongly agreed.

"Young Master, Reiju, Sister Makino has finished making dinner."

Charloss came to the captain's quarters and spoke to Lin Yu and Reiju.

Because of her uniquely gentle, older-sister aura, Makino had already become the big sister of the God Slave.

"Let's go. I'm hungry too."

Lin Yu rubbed his stomach and stood up.

Another day passed.

Lin Yu's God Slave finally arrived in the waters near Alabasta.

"Did you bring everything?"

Lin Yu looked at the women who had changed into dancer outfits and grinned.

Alabasta was a desert nation with a hot climate, so Lin Yu had thoughtfully prepared cool dancer outfits for Nojiko, Kaya, and the others.

"Big Brother Lin Yu, do we really have to wear this?"

Kaya wrapped herself tightly in a layer of sheer gauze and looked at Lin Yu with a flushed face.

Like Kaya, Makino also covered herself with sheer gauze, looking somewhat uncomfortable.

Yet this half-hidden style only made the two of them even more alluring.
