Opening: Devil Fruit can be upgraded

"Gion? Peach Rabbit?"

After so many years, Roger was a little vague about some things.

"Yes, it's the peach rabbit sister who is as famous as you." Kuina smiled softly

"That's right, Sister Gion will definitely beat you."Why did Tina say that?

Roger looked at Tina and didn't refute her. She already knew Tina's character.

""Let me see your slash." Roger said to Kuina.

Kuina nodded, then moved closer to the stern and swung her sword towards the sea.

Shimokatsuki Style. Sakura Dance!

Kuina's unique silver moon-shaped slash was slashed out, the slash was five meters high, and there was an illusion of cherry blossoms falling beside the slash, just like Vista, the flower swordsman of the Whitebeard Pirates.

Kuina was not as lucky as Roger, who could quickly increase her strength and physique, so her slashing ability could only reach this level, and there was still a big gap from the great swordsman.

"This time I must get the upgrade points and help Kuina get the devil fruit."Rogge thought to himself.

"How is it? Rogge?"Guina looked at Rogge who was in a daze with admiring eyes and asked, as if waiting for Rogge's praise.

"Very good, you are very strong, but there is still a big gap compared to Hawkeye. To become the number one swordsman, you still need to work hard."

"Well, I also know what Hawkeye is like from Grandma Crane, so I naturally don’t want to challenge him so soon."

"Are you really going to challenge Hawkeye? Kuina."Tina asked in surprise

"Of course, this is my dream!" Kuina nodded seriously.

"……Okay, I thought you were just kidding."

……

In the swimming pool on the deck, Kimi enviously watched Rogge and the other two chatting happily.

Papagu noticed Kimi's envy, so he put his hands on his hips and said,"Kami, even if Rogge has fallen in love with someone else, as a master, I

, Papagu, will never let you be alone." Kimi blushed, then returned to normal:"What do you mean by falling in love with someone else? It's just that my brother wants to teach my two sisters how to fight. I'm a mermaid and I can't fight, so of course I can't fit in with them."

Kimi said it as a matter of course, but she couldn't hide the desire in her heart. She also wanted to fight, wanted to discuss with sisters Kuina and Tina, and wanted Rogge to teach her how to fight.

"Humph, I think Roger has forgotten you, and Kuina is the same. When they were at the Navy Headquarters, they said they wanted to get close to you, but they were actually worried that you would snatch Roger away."Papagu said, feeling dissatisfied on behalf of Kemi.

"No way, Sister Kuina has been very good to me during this period, it's not like what Master said."

Kami is still a natural idiot. Even Roger noticed that Kuina was jealous that day, but Kemi in Kuina's arms didn't feel anything.

""Kami!"

Papagu was about to say something else, but Roger came over at this time.

"Brother." Kami shouted excitedly.

Roger squatted beside the swimming pool, then touched Kami's head and said with a smile:"I found a lot of books about fashion design in the human world for you, I will show them to you later."

Kami was about to nod happily, but Papagu said first:"How can the human fashion design concept be the same as the fishman's design concept? As the top designer of Fishman Island, I seriously doubt your motives for your behavior."

"……Starfish, are you drifting?" Roger had the urge to hit Starfish again.

"What starfish? My name is Papagu, the designer and president of the Fishman Island fashion brand"Prisoner Brand" Mr. Papagu!"

Rogge's forehead veins popped up, and then he grabbed Papagu and threw him into the cabin.——"Ah~ You will regret it, Roger!"

"Regret? I regret your head!"I thought to myself, and then turned to look at Kemi.

"Kami, I'll move the books to your room so you don't have to move them back later."

"Well, thank you brother... Is Master Papagu okay?" Kemi asked worriedly.

"It's okay. That starfish has been eaten by sea beasts so many times and is still alive and well. What's there to be afraid of if it falls?"

Rogge's words made Kimi feel embarrassed. She also knew that she was a fool, so she was often eaten by sea beasts, and Papagu was implicated by her.

"I hate my brother." Kami said with a blush on his face.

"Hahaha, what does it matter? With me by Kami's side, I will never let sea beasts eat you again. From now on, only Kami will eat sea beasts."

Kami was stunned for a moment, then said like a peach:"Oh, eat sea beasts, eat sea beasts~"

Rogge touched Kami's head again, then walked into the cabin and threw Papagu back——"Damn you, Roger, you will regret this!"

""Same words again, boring starfish." Roger spread his hands and walked to his room.

Kuina and Tina did not mean to alienate Kemi, but as Kemi said, they lacked an important 'common language'.’——So when Kuina and Tina were training, they had no way to bring Kemi along.

He went back to the cabin and sorted out the books he had put in place earlier.

《Fashion Design Basics》

《A must-buy series for beginners of fashion design》

《Advanced clothing design》

《Karl Lagerfeld's Fashion Design Experience》

……

After sorting, there are dozens of books in total. If they are held together, they can cover Roger's entire head.

"Hmm? This book is……"Roger found a familiar face among a pile of books he had never read before.——《One hundred etiquettes of being an apprentice》！

"Haha~ This is Nami's favorite book. I haven't seen her for so long, and I don't know how she is doing. Has she become a swordsman?"

Roger said with a smile as he picked up the book and flipped through it.

Chapter 1: Ten Skills of Apprenticeship

Chapter 2: Get to Know the Teacher's Heart and Win the Teacher's Stomach

Chapter 3: Learn to Flatter

……

"What kind of perverse logic is this? The best way to learn skills is to use money? Hmm~ I think I accepted Nami as my apprentice because of her money... Let's see if he is right about one thing, and the second method is - the beauty (good-looking man) trap? It seems... That's right, I accepted Nami because she is pretty.……"

"Forget it, just read what he wrote in the last chapter.

Curious, Roger turned to the last page of the book. The title of this chapter is - How to make the teacher teach you the most profound skills.

At first glance at the title, Roger thought it was interesting, but after reading the first method, Roger was overwhelmed.

Method 1: If you love his (her) ability, marry him (her). If you get her (him), are you afraid of not getting his (her) greatest ability?
