"Hurry up and transfer all the books!"
"Get your money! More is needed!"
"The Fish-Man Karate and The Fish-Men Jujitsu are like this..."
Robin wanted books, Carina wanted wealth, and Shinra got all the martial arts and everything that took their interests.
As for everyone's impression of him—
"Damn that Hody Jones!"
"Why should he provoke a disaster?!"
"Die, Hody Jones!"
"....." Hody Jones.
As everyone saw the sand filled with the Fish-Man Island, no one dared to become an enemy of Shinra or provoke him. Because of this, they became angry at Hody Jones, who had brought the disaster to their home.
Shinra and his group had only come to visit Fish-Man Island for a while, then decided to leave. However, they were unexpectedly provoked, so was it wrong of them to fight back?
As for Jimbei, although he was hurt, he still forced himself to teach Shinra everything he knew. Frankly, he didn't have many expectations, thinking that a human would have a hard time learning the martial arts created especially for the fish-men.
"Jimbei, you should rest for a bit!"
"No!"
No matter what, everything was his fault, and Jimbei couldn't raise his head since he knew that if he was careful enough and talked with Shinra peacefully, Shinra would get angry and destroy the Fish-Man Island.
Only—
"Fish-Man Karate: Five Thousand Tile True Punch!"
Shinra sent a powerful punch that generated a shockwave and moisture in the surrounding area.
BOOOOOOOOOOOOOOOMMM!
"It's simpler than I thought."
The martial arts in the world of One Piece were simple, and what made it frightening was the physical ability of all the people in this world, since some were born as monsters.
"....." Jimbei and everyone.
"Teach me Jujitsu, too."
"Y-Yes!"
As Shinra mastered the Fish-Man Karate and the Fish-Man Jujutsu easily, all the fish-men and mermaids, who saw all of this, had a complicated mood as they trained for so many years to master those two martial arts, yet they were mastered by him in just a single glance. While his mastery wasn't perfect, it was almost perfect, making them hopeless and frightened by the full potential of this human.
Meanwhile, Shinra, who had mastered the Fish Man Jujutsu, felt like this martial art was more or less similar to the water ninjutsu, but without hand signs.
While it was convenient, it wasn't that powerful, Shinra thought.
Moreover, water was a simple element, and what made it dangerous was its volume; the more water, the better, but it took a lot of energy.
As Shinra thought of energy, he somehow thought of the Batto Batto no Mi, Model: Vampire as soon as possible, as it could help him to get energy from blood or the life force of people.
Meanwhile, the king, the nobles, and the ministers of the Ryugu Kingdom were in despair as they couldn't contact the Whitebeard Pirate or anyone!
At this moment, as Shinra used his Camouflage Space, no one could contact this island, and this place was completely isolated.
"Tell your king that if they do something stupid, I will kill him and everyone first."
"Right away."
When the king and those who wanted to contact the reinforcements to help deter Shinra all bowed and apologized directly.
"We're sorry!"
No matter what their status was, whether they were kings, nobles, wealthy, ministers, or even if they were above many, in front of overwhelming power, they could only beg.
Shinra smiled and asked, "Shouldn't you do your best to fight me, and would rather die than apologize and beg like this? Come on! Show some fighting spirit!"
"..." Everyone.
"We were too stupid before, but let us apologize for our mistake. If it isn't enough, then you can kill me."
"Father!"
Three princes looked at their father in shock.
"Don't stop me. It's my fault for being blind, thinking that I can contact Whitebeard! Tell Shirahoshi that I am sorry! I am such a failure as a father—"
Slap!
Shinra slapped the king of the Ryugu Kingdom and said, "Shut up."
"Ah, yes."
Neptune was so submissive.
"....."
Everyone was humiliated, yet what could they do?
"By the way, what is this?"
Shinra took out a pill from his pocket and showed it to everyone.
"T-That's... Energy Steroids! How did you get that?!"
"I got them from the soldier who wanted to kill me before."
"....." Everyone.
Was Shinra lying?
Yet, what was the point?
So, they knew well that Hody Jones, the cause of all of this trouble, also stole the Energy Steroids!
Still, the Energy Steroids are special pills that can greatly enhance the physical strength of the consumer, as well as increase their muscle mass, but the pills will shave some time off the user's remaining lifespan.
"Hmm...."
"Will you drink it, Shinra?" Carina asked as she laid her chin on his shoulder, staring at the pill curiously.
"Let's see how it goes later."
Would Shinra eat the steroids?
Frankly, he planned to take them since the effect was amazing. One pill enhanced the user's strength two-fold, and its impact was cumulative, so taking more would further enhance his strength.
The only problem was that as he took more, the medicines would lose their effect and shave away at his life.
Yes, this improvement might not last forever, but as he took more, as he took more till the overdose, it would give him a great improvement.
Yet, he knew well that as he had done to the Fish-Man Island, he had become the enemy of the Whitebeard Pirate, as this island was Whitebeard's turf, so he knew that he had to prepare himself, if the situation really called for it.
As for the side effect of having his remaining lifespan taken, frankly, he felt that it was nothing since many ways existed to increase his lifespan in this world, including by using the Batto Batto no Mi, Model: Vampire.
"I think that you had better not consume it." Robin folded her arms and looked at Shinra strictly, taking the pills away from him.
"Still, let's keep them, then. Hopefully, I won't use them."
Anyway, it wouldn't hurt to keep the energy steroids.
"..."
Robin hesitated, but in the end, she followed his words, keeping them in a secret place as she let out a helpless sigh. Still, she looked at Neptune, who was still submissive, and asked, "By the way, can I ask something?"
"Ah, me?"
"Yes."
"W-What is it? Is it a treasure?"
"Do you know who Joy Boy is?"
"....."
Neptune blinked his eyes and showed a dumbfounded expression. "Y-You..."
"Do you want to say more than let him destroy your kingdom?"
"Ah, I am sorry."
Neptune quickly shut his mouth, then asked with a forced smile. "W-What do you want to know?"
After reading the Poneglyphs, instead of a piece of history, what was written was only an apology from Joy Boy to the princess of the mermaid, Poseidon.
Poseidon aside, who was Joy Boy?
Robin was curious, and facing her question, what could Neptune do except give an answer?
Yet, hearing Neptune's answer, Robin and Carina looked at Shinra with a strange gaze.
