Four Emperors.
It was the title given by the World Government to the four powerful pirates who had dominated the New World, only one rank lower than the Pirate King.
Yet, frankly, instead of the title to show how dangerous those pirates were, Shinra knew that it was nothing but just a conspiracy, so those four pirates that had dominated the New World would be targeted by the pirates, who entered the New World, having them fight each other, and defeat those strong pirates without doing anything.
Even so, the fact that these four pirates were able to gain such a title meant that their powers couldn't be underestimated, and each of them was really an existence that most people could only look up to in their lives.
Was the World Government helpless towards them?
Shinra didn't think so since if the World Government wished to, they could erase one of the Four Emperors easily, and he knew well the power of the World Government; the ruler of this world for the past 800 years wasn't just a simple Marine.
On the other hand, the Four Emperors hadn't been created for hundreds of years, so naturally, their power was limited, and they could only control the New World.
However, the enemy of the World Government wasn't just the Four Emperors, and with their budgets, instead of using them to defeat one of the Four Emperors, it was better to maintain their status quo, as the benefits that came from defeating those four strongest pirates were minimal.
The essence of the war was about profit.
Whether it was resources, money, lands, or others, as the Four Emperors lacked that compared to the World Government, it was better to just bully those small countries or kingdoms that didn't have powerful fighters and got an easy money, then having to fight powerful opponents and spent a lot of their incomes, budgets, power, and times on those Four Emperors.
Meanwhile, instead of fighting the World Government, the Four Emperors just wanted to maintain the status quo, or tried to aim to become the illusionary goal known as the King of Pirates, which was declared by the Gol D. Roger.
Regardless, everything was in balance, and everyone lived peacefully on their own, so why should they cause trouble and make their lives uncomfortable?
Nevertheless, as Shinra had killed Caesar, he knew that he had made an enemy of one of the Four Emperors known as Big Mom, the strongest female pirate, the leader of the Big Mom Pirates, and also the founder of Totto Land, Charlotte Linlin.
While the reason why Big Mom wanted to turn humans into giants was still unknown, Shinra knew well that she was a formidable opponent.
Still, when he thought of Big Mom, he wondered why the old woman in this world was just too horrendous.
"...even though she was so beautiful when she was young."
When Shinra compared Big Mom's appearance when she was under 40 and when she was above 40, he could only let out a helpless sigh.
"What did you say?"
"Nothing."
"So, are we going to be okay?" Robin asked with a hint of anxiety, feeling worried since their opponent wouldn't be on the same level as they had fought before.
"Well..." Shinra thought for a moment and recalled all the records about the Four Emperors, including their strength, abilities, and everything, then came to a conclusion. "Whether it is a direct battle or assassination, I don't think that I can defeat them."
"..." Carina and Robin.
"However, if I run away from them, then they won't be able to catch me."
"...." Carina and Robin.
Shinra's strength might not be comparable to the Four Emperors, at least, currently, but it was just a matter of time since sooner or later, he wanted to face the Four Emperors, especially after he gained the Batto Batto no Mi, Model: Devil.
Still, before he got that Devil Fruit, he thought for a moment and looked at the record of the laboratory until he discovered what he sought. Frankly, compared to Caesar's research, he was more interested in Vegapunk's research, and fortunately, it was still recorded within this faculty.
As for why Vegapunk didn't erase all the data records of his research on this island, Shinra could only think that it was because this guy was so saintly that he wanted to share his knowledge with the world.
While Shinra didn't understand Vegapunk's thought, since how could one share what they had been working hard to "everyone" without any greed, the only way to explain this was because Vegapunk probably felt that the knowledge that he had learned wasn't worth mentioning, or it was simply the arrogance of a genius like how wealthy people would share their money to those without money like a charity.
Charity.
It was probably the best word to describe Vegapunk's actions.
Still, while Shinra was calm, the others weren't calm.
"You are dreaming! Do you think that you can escape from the Big Mom and Young Master? You are all going to die here!"
While her body was all weak, Monet's mouth was still as strong as ever.
Shinra stared at Monet's fleshy, pink lips for a moment before he stood up, ready to get the last piece for his escapade on this island.
"Where are you going?" Carina asked curiously.
"Well, there is something interesting here that will help me to escape easily."
"Huh?" 2x
Monet, who heard this, was dumbfounded, but Carina and Robin didn't doubt him and followed him to the place that he wanted to go.
While Monet was curious, she couldn't move, and at this moment, she also realized Shinra's weirdness, as she realized that Shinra could control all of the soldiers on this island, yet the problem was... how?
What did Shinra really do?
This young man was an enigma, mysterious, and all of his means were just too weird for her to understand.
Monet might have confidence in her Young Master, Doflamingo, but if he wasn't careful enough, then—
'No, Young Master is the strongest!'
As she thought so, Monet continued to think, imagining Shinra's horrible fate when Doflamingo arrived on this island.
Still, Shinra had never thought much of Doflamingo. Instead, his focus was on the room where he discovered a fruit with the shape of a blue apple with double ring patterns throughout the fruit, the outer rings being darker green than the inner ones, lighter.
"This... is this a Devil Fruit?"
Carina and Robin looked at the Devil Fruit that was held by Shinra curiously.
Yet, Shinra didn't answer their question, but activated his Eye of Usurp, aiming to take away everything on this Devil Fruit before slowly transforming into a different creature before he returned the Devil Fruit in the box again.
"....." 2x
There were many things that the two wanted to say, but before all of that, they had to face the guest who had come to this island first.
