Opening: Devil Fruit can be upgraded

In the dojo, Kuina, wearing a cherry blossom kimono (Wano Country culture), gracefully poured a cup of tea for Roger.

"I didn't expect you to have such a beautiful side." Roger said with some admiration as he looked at the beautiful Kuina in her cherry blossom kimono.

"Drink." Kuina ignored Rogge's appreciation and replied coldly

"Oh, okay." Roger didn't care, he picked up the small teacup with both hands and took a sip.~

"Do you usually drink tea like this?" Guina sat opposite Rogge with amusement, then picked up the teacup in a ladylike manner and took a sip.

"This is the right way to drink it"

"……"

Rogge couldn't learn Kuina's tricks. Even if he tried to learn them, he would still look weird. Either he looked too feminine, or he would just take a sip of it. He wouldn't look like Kuina, who is so attractive to both the elite and the masses.

"This is your look, so don't embarrass me. I'm a rough guy."Rogge held his cheek with one hand and pouted.

"All right." Kuina didn't care about Rogge's rudeness,"Then let's get straight to the point. What is a devil fruit?"

"Zoro has already answered this question, but I would like to add that the fruit that is commonly circulated on the sea is the fruit that is cursed by the sea."

"Fruit cursed by the sea?"

"Yes, as Zoro said, people who eat devil fruits will become afraid of sea water, and the specific feeling is physical weakness and inability to use abilities."Rogge explained

"Are all devil fruits the same?"

"No, there are three types of devil fruits: animal, psychic, and natural."

"Animal type, psychic type and natural type?"

"Yes, among the three fruits, the natural fruit is recognized as the strongest fruit, but this only means that the natural fruit has a low lower limit and is relatively easy to develop.……"

"What is development? Isn't it possible to acquire abilities after eating a devil fruit?"

"I will explain this to you later. Don't interrupt me now, let me finish what I am saying."

Kuina also felt that she was being rude, so she nodded in response, indicating that she would not interrupt Rogge again.

"Among the three types of fruits, the natural type is the strongest, and there is no specific ranking for the other two types of fruits, because the lower limits of the two are not much different.

After eating the animal-type devil fruit, the ability user will have the ability to transform into an animal, and it will also enhance the physical fitness of the ability user. This type of fruit is also the most suitable for you. The psychic-type devil fruit is full of fantasy. It can give people the ability to master and change elements. My cold fruit belongs to the psychic type.

Finally, there is the strongest natural devil fruit. The power of this fruit lies in that everyone who eats this fruit can be immune to physical attacks!"

"Immune to physical attacks!" Kuina finally couldn't help but exclaim in surprise.

Rogge glanced at Kuina indifferently, and Kuina turned her head away embarrassedly.

"Not only that."Rogge continued,"Even most elemental attacks cannot cause harm to the user of the Nature Fruit ability, and this ability is passive. No matter if it is a sneak attack or anything else, as long as the user's body is broken, the body will automatically transform into an element.……"

At this point, Kuina's face was already red, and she seemed to have a lot of questions in her mind, and she couldn't help asking them.

But it was understandable that no one could suppress their curiosity about such a magical thing that suddenly appeared in their world.

"Just say whatever you want to say."Rogge said helplessly.

"Uh-huh~" Kuina shook her head to indicate that she was fine.

"……"

""Speak, it's okay." Rogge stretched out his hand and pinched Kuina's face, breaking Kuina's attack.

""Ah! What are you doing?" Kuina scolded with some embarrassment.

"Seeing that you are feeling uncomfortable, I am just trying to help you. Go ahead." Roger did not behave like a gentleman at all and urged

"……"Kuina rolled her eyes at Rogge, and then said:"If the natural devil fruit ability users are invincible as you said, then how can we swordsmen defeat such guys? Even the world's number one swordsman can't do it, right?" Obviously, facing the temptation of the devil fruit, Kuina still did not lose her nature and stuck to the sword.

"It's not invincible. As I said, the devil fruit is cursed by the sea, and so are the people who eat it. As long as they are touched by more sea water, they will lose their ability to fight. In addition, there is something called seastone in the world. This thing also has the power of the sea and can suppress the devil fruit."

"Seastone? So apart from these two methods of using external objects, is there no other way to defeat the natural devil fruit ability user?" Kuina looked at Rogge seriously and asked. She was eager to know the upper limit of the swordsman.

"Of course there is, it is a kind of ability, and its name is - domineering!"

"Domineering?"

"Ahem.

Before Rogge could continue, Koshiro suddenly appeared and interrupted Rogge's answer.

"Father. Seeing Koshiro coming, Kuina immediately stood up and saluted her father solemnly.

"Well, you go down first, I have something to say to Roger. Koshiro nodded and ordered

"But……"Kuina looked at Rogge with hesitation, obviously unable to suppress her curiosity about 'Haki' and Devil Fruits.

"It's too late, let's talk tomorrow."The usually gentle Koshiro rarely showed a serious expression.

"This... is, father." Kuina finally did not dare to resist her father's will.

After a while, when Kuina walked away, Rogge said lightly:"Master, what are you afraid of?"

"Afraid?"Koushirou regained his gentle side, seemingly puzzled by Rogge's words.

He ignored Rogge's impoliteness and sat down elegantly opposite Rogge, pouring himself a cup of tea while saying

"I have nothing to be afraid of. I just don't want Kuina to do the impossible."

"Impossible? Do you mean the greatest swordsman?"Rogge asked curiously. In Rogge's opinion, although there is no so-called female greatest swordsman, there are also women who have become swordsmen, such as Tashigi, Taotu, and Oni (Big Mom's subordinate).

Taotu, in particular, may be a great swordsman, after all, she is a candidate for admiral.

So it is too arbitrary to simply say that women cannot become the greatest swordsman because of their physical condition.

"Of course, there has never been a female swordsman who became the greatest swordsman in history, and it is even more difficult for women to become a swordsman."Koshiro said with a smile.
