Fishman Island

Izan was alone on the deck as the rest went inside. Izan gazed at the sea in front of him. They had been diving downwards for a couple of hours already and it was starting to get darker as the sun couldn't shine this far down.

Yet Izan was able to watch the fishes easily, he could see the ripples in the water as the fishes swam around. A small smile appeared on his face as he gazed at the peaceful description of a sea-life.

"…" Izan didn't say anything, but he felt something appearing behind him. He did already know who it was, his lips opened up as a soothing voice escaped his mouth. "Jiutian, will it take us long time to arrive at Fishman Island? From what Robin told us, it is 10 000 meters below the surface."

The person that arrived behind Izan was of course Jiutian. She gazed at the fishes in front of her as she answered Izan with a calming voice. "We are already beyond 6 000 meters below the surface. If nothing major happens, it will take four hours to arrive, and less if we manage to catch a stream that is heading downwards." Jiutian was able to use her Haki and own sensation powers to map out her surrounding ten kilometres.

Jiutian was able to sense strong sea-beasts, people above them and even the Fishman Island below them. As she was using her senses, Jiutian was able to sense a stream which was going downwards in a fast speed. "I found a stream…" She spoke the directions and Defying seemed to listen and it turned towards where Jiutian had spoken of.

"Jiutian…" Izan was speaking slowly as he continued gazing at the sea. "I have set a goal to archive during our stay on this world. At what time did you intend for us to leave?" Izan knew that this was barely a training ground for them, but this world had made Izan become interested in its mysteries.

Jiutian raised an eyebrow before replying. "We came here for the Haki practice, we would have finished this world after being decent in it. It would have been at the level of fighting the Emperor of the Seas with your Haki alone, at that time I would have told you that we had reached our goals and travel to the next world." Jiutian's small goal of becoming decent in Haki was of matter of fact, she had already been able to progress her Haki to become stronger than everyone on this world.

But, it was only because that Jiutian's body and soul was already strong enough to handle it. Compared to her body right now which is weakened, her real strength could decimate this world with a flicker of her wrist. But what Jiutian could do now was to destroy an island easily. A sigh sounded out from her mouth, but she didn't care that much about it for now, as she was happy that she could stay with Izan.

Izan nodded, he stayed silent for a whole minute before speaking once again. "Jiutian, this world has shown me much more than what I had thought it could. The Navy, the World Government, Revolutionary Army and the Emperors… Justice, Chaos and Evil… The four factions have a share of their own Justice, Chaos and Evil in them." Izan's eyes squinted slightly as he continued speaking. "There must be a reason that can explain things in more details, I simply can't believe that it's only just this. The Celestial Dragons are hiding something, the Void Century. Yet, I have a guess that it is because of someone else that they are hiding it…"

"… You mean the one I sensed during the war?" Jiutian asked as she stared at Izan's back. She had only told Izan only once that there was a strong being near the Celestial Dragons, yet Izan was able to speculate that it had something to do with the Void Century and the Celestial Dragons are merely acting as a cover for that being.

This was one of the reasons that Jiutian loved Izan, he could create hypothesis on the basis of minimal information. And at most times, Izan's assumptions would be correct. Izan was able to do this because of his strong soul, he was able to perceive everything in short amount of time and think much faster than normal humans.

"Yes." Izan nodded before a smirk appeared on his face. "There is no way that a strong powerhouse would be submissive. But there is one thing that doesn't make sense in my thinking right now. Because I want to guess that the powerhouse has been alive since the Void Century, but it contradicts against the Laws of this world, there shouldn't be anyone being able to live for this long." Izan's eyes narrowed slightly as he continued with a cold voice. "Unless…"

"Unless he or she was able to understand the Laws of this world." Jiutian finished off after Izan, she couldn't sense much of that being, as it was very far away from her. "It shouldn't be impossible, just very hard. If that being did understand some certain Law, then living for a few centuries should not be a problem."

"If I would speculate further ahead, I can guess that, that the powerhouse is the ancestor of the Celestial Dragons. It would make sense for why the Celestial Dragons are ruling the world, and even more so as they are wanting to hide the past for the rest of the world." Izan chuckled as he thought that he would have to fight a being almost a thousand years old in the near future. Izan wasn't afraid at all, a smile crept on his face as he thought of how fun it would be to destroy the Celestial Dragons, including the powerhouse behind them.

"Hehehehe…!" Izan started laughing out loud as his eyes squinted and turned sharp. "I will kill that person and show him for trying to mess with me…!" A sharp and chaotic pressure surrounded Izan, it made even Defying heavier as it sailed downwards much faster.

Luckily Defying was pretty strong too as Izan's pressure didn't manage to damage a single piece of it. Defying was able to even sense Izan's intent, a much heavier pressure surrounded the whole ship as it merged with Izan's pressure.

Izan wasn't able to notice this, but Jiutian did. She furrowed her eyebrows slightly as Jiutian was rather surprised by how fast Defying was able to gain a conscious, even being able to create its own intent and understand those on board of it. Yet, Jiutian's expression turned soft and she smiled as usual, she was indeed surprised, but she was in the end happy that Izan was able to gain such a companion as Defying.

The time passed by and hours went by as Defying was sailing through the stream and it neared closer to Fishman Island.

When Izan was able to see Fishman Island in the horizon, he called out for everyone to see. Perona, Hancock, Nojiko and Robin went to the deck and stared at the island in a large bubble. As they had not arrived yet, the six of them sat around a round table as they drank and ate happily while talking.

At one point, Robin had been daring enough to sit on Izan's lap with a slight blush on her face. When she sat on Izan's lap, she felt calm and Robin was dozing off as she was feeling Izan's hand stroking her hair.

Izan didn't mind that his wives would act like this, he was rather happy that his wives would seek for his attention at times.

But this calming atmosphere didn't last long as they were nearing the island. As Defying went through the bubble wrapped around it, dozens of fishmen surrounded Defying with different weapons in their hands.

Izan turned his gaze at them before shaking his head.

The reason Izan was shaking his head was because Perona stood up with a sharp glint in her eyes. She turned towards the pirates and walked to the edge of the deck. Half a dozen ghosts appeared around Perona, her lips opened up and a beautiful voice sounded out from her mouth. "Who the heck are you scums!?" Despite her beautiful appearance and voice, Perona's wording were simply crude…
