One Piece: I Reincarnated as Ace with a system

I'm now six years old, so I decided I'm going to learn how to swim. It should be a simple task because, in my original world, I was a pretty good swimmer. I jumped off the edge into the seawater splash.

I've been in the water for about an hour, and something weird has been happening ever since I got here. All the seawater around me is coming my way; it's like I'm a seawater magnet. I wonder what is going on. 

'Congratulations, you have met the requirements to awaken the sea system.' Hang on a minute, the sea system awakened, and what requirements is he talking about? 

If I were a person who usually drinks, I would seriously consider the possibility that I'm currently drunk. What is going on over here? I awakened a system. Why did I awaken it now, and why is it called the sea system?

Oh, I think I get it now, the voice said, The system that I awakened was called the sea system. Maybe I needed to absorb an amount of seawater for it to be awakened. If that's true, talk about bad luck. Imagine if I spent more time in the sea than in the river before. Okay, I have the system, so how do I use it? How do I even open it? Is there a word needed to open it? [Open] 

Gol D. Ace 

possessed Talents/Abilities/Skills: 

None. 

Total Points: 0

Well, it looks like I don't have any talents, well, not yet, at least for some reason. I know this system is powerful. If this system is half as powerful as it is, then I won't need the Mera Mera no Mi(Flame-Flame Fruit) or any other devil fruit, for that matter. For some reason, this system is extremely familiar; it's not like I've been transmigrated and granted a system before. What is going over here? Why is it so familiar to me?

With this system, it should be exponentially easier for me to get stronger. I need to be stronger than the original Ace was before he died because I'll be King of the Pirates if it's the last thing I do. I was born as one of my favorite characters, so I figured I might as well be the greatest pirate the world has ever seen. 

Oh, I remember what this system reminds me of It is as if the all football abilities are mine system and steel-eating player combined I can copy peoples talents by accomplishing a specific task and you can improve said ability by absorbing sea water if my theory is right this is the best system someone in my situation could ever ask for especially in the One Piece world.

Well, I'll be teaming up with Sabo soon because he's already sneaking out of his house. Besides, if I can copy talents, I think I'll be able to get some from Sabo, and we'll be able to build our hideout a little earlier, even before Luffy comes.

Well, knowing how things went in the original storyline, Sabo will start being miserable soon. I can't just leave the guy to sleep in the trash if he's going to leave his house.

Before I go and get him, I have to make sure I know everything about the system. What else can it do? What do I use those points for? Maybe I can use them to improve my ability once I have them?

Unfortunately, right now I have no ability and no points to use, I just have a theory on how the system works and no means to test it, at least not yet, like Shikamaru from Naruto would say, man, what a drag!
