One Piece: The Power System

Author Note: I just wanted to put it out there that I got Hydrogen and Nitrogen Mixed up. What I meant to put was Nitrogen which is naturally cold. Hydrogen needs to be frozen at certain temperatures to get to its chilling temperatures. I will go back and changed that, so don't be confused. He also fused the Balrog fruit and "Nitrogen" Fruit, not the black flame fruit which he still has.

Rein sat in his hotel and ordered his food, which were many dishes that required two waiters to bring in. They used a cart to bring in his food, so it wasn't a problem for them. The waiter bowed and left soon after the delivery. Rein took off his mask and began to chow down with no restraint, the food the best he'd tasted in this world!

After eating all the dishes with a satisfied feeling, he buried and put his mask back on to call the waiters. Once they arrived, they were dumbfounded seeing the empty plates and platters, they looked at Rein again who was rubbing his stomach. They didn't want to stay too long with the starring they were doing, so they immediately left with the carts of empty plates and platters. This man was a noble in their eyes, if they stared too much then it would bring unwanted trouble.

He only booked this hotel room for one day, so after, he would be on his way. Rein was only waiting for the auction and night to fall, he wouldn't be present for the auction during its event. Since he was waiting, he decided to check the system for a couple of things.

☆ Shop ☆

★ Haki & Rokushiki Training

★ Devil Fruits

★ Medicinal & Strengthening Pills

★ Weapons & Armor

★ Miscellaneous Items

Rein brought up the system store and immediately clicked the Miscellaneous Category.

⋆ Offense

⋆ Defense

⋆ Scared Relics & Consumables

⋆ ....

⋆ .....

Rein just clicked the Defense category and many-body defensive abilities popped up. They cost quite the amount. Rein had managed to gain the ability Cold Resistance because of the devil fruit he had consumed, the Nitrogen-Nitrogen Fruit! He had also gained Heat resistance but these abilities still had to be leveled up like all of his. He only had 299,850 System points, he wanted to save up for holy water which would liberate him from the Devil Fruit's Curse of the sea.

"The Holy Water is the main thing I need, Seastone could prove to be troublesome for me if it is used against me." Rein wasn't worried about falling into the water since he could simply freeze it over, but this didn't apply for Sea Stone, as it would still instantly weaken him.

Rein had too many things he wanted from the system but couldn't afford them yet. He closed the system store and went to lay on his bed for a nap. He had gotten up early for Ace's departure so he was still quite tired.

Perfect Auction House!

The man in Red was just walking out of his office with a somewhat depressed face. He had been completely ripped off by Rein not too long ago.

"Raul, get over here this instant!" The man in red roared and a short man in a black suit came over, his features were hard to look at. He had acne all over his face with droopy eyes and a bald head. The man had pus coming out of his baldhead, due to the huge pimple he just popped!

"Yes, sir, what can I do for you?" The in black asked

"The man from earlier, I want you to check his family background!" The man glinted fiercely: "Ask around about the man in the white suit and mask. Make sure you get this done by today and before the auction ends, do you understand!? No slip-ups!

The man bowed slightly: "I will get the job done, can I take some people to ask around with me on this assignment?" The man in black asked his boss, and the man in red agreed that it would be much faster if he had assistance. The man in black left in a hurry after his boss agreed with his request, he was on a time table, so he had to work fast.

"Boy, if I find out that your family isn't worth much, HAHAHA!" The man in Red laughed crazily as he walked back into his office.

Time went by as hours passed. Luffy and Erica were wondering where Rein could have gone and decided to eat without him. Night soon came, at this time, Rein was getting out of his bed. He went downstairs to check out of this place once and for good.

Once he left the luxurious hotel after he paid for his stay and what he had eaten, he walked to a secluded dark alleyway. Rein looked around and used Observation Haki to find that no one was in the area. He took to the sky straight upward, his destination, Sabo's old home where Stelly should be. Sabo had told him how his house looked and even how to get there when they were robbing during that time, so he knew.

The darkness acted as his veil, he had completely changed his clothes in the alleyway as well. He wore an all-black cloak that hid his body and most of his face. Rein flapped his wings and eventually came across the building Sabo described. He also recognized the insignia of Sabo's family from the anime.

Rein silently landed on the mansion-like building, he had to concentrate hard for this. His observation Haki was good but not on such an amazing level. He had to find Stelly first before he could execute him. Rein remembered that Sabo's room was close to a tree from the anime, this room should be owned by Stelly since he took Sabo's place.

Rein saw the tree with ease, the tree sabo used to jump down from to escape his room. He flew towards it silently and opened the window. Someone was indeed in this room, it was one person at this time who appeared to be asleep. Once Rein got closer, he confirmed that it was indeed the Stelly from the show.

Rein grinned with this discovery! Rein was now at the bedside looking at Stelly.

"Pss! Stelly~~~!" Rein's eerie voice came over Stelly, he felt a chill run down his spine. Stelly turned around and opened his eye to see Rein next to his bed.

"Gasp!" Stelly was about to scream but Rein put his hands over his mouth to silence him. Stelly looked at Rein in horror, he was naturally a scared person anyway.

"You've doomed Sabo to be destroyed by the celestial, if you had shut your mouth, none of this would have happened." Rein wanted Stelly to understand why he was here. Stelly's eyes dilated as his mouth started to freeze slowly.

"Shhh! It'll be over quick, there will be another king of this Kingdom and you're not it, bye-bye." Soon, Stelly was frozen solid, not just him, the whole room turned into an icebox!

Ding! Congratulations Rein, you've Killed future King of Goa Kingdom Stelly, you've received: 2 Skill Points

After that was done, Rein immediately left the mansion through the window he came from. At this time, the auction was taking place and he was heading there. Rein wasn't going there to participate in it, but to rob it. He needed every bit of money he could get, he needed to buy Adams wood and needed to pay to have the ship built. You could only imagine how much that would cost for him later, so he wanted to prepare now.

Rein arrived at the auction and snuck in from the top. The Perfect Auction House had sent news that there was a special item being auctioned tonight. Rein cloaked himself in the shadows with his devil fruit ability as he went unnoticed in the darkness. This ability was limited so it wouldn't work on decently strong people. If he could awaken his devil fruit then he would be able to hide in another person's shadow which would be amazing for assassinations and sneak attacks.

Rein made his way deeper into the auction house, he soon came to a vault that was being loaded with money from the auction. It already had many valuables in it, this seemed to be where they stored all their treasures.

This vault was usually locked down so no one could get into it, there were several strong-looking men around it. They were watching the people who were loading the money and valuables into the vault closely, they had threatening expressions on their faces that seemed to be saying, 'I dare you to steal!

Rein could hear a conversation between two of the big men that seemed to be the leaders of the other strong-looking men. "The boss is amazing, he is selling a power fruit at the auction today. The nobles won't be able to resist when they see it and that'll spend a lot of money just to get it!" The man laughed as saliva splashed everywhere.

"Yeah, the man who gave it to him for auction hasn't appeared yet, but for his sake, I hope he doesn't haha! Oh, wait, I hope he does, haha!"

The man gave a knowing laugh.

"Huh! Why is that? Did something happen?" The saliva boss watcher asked confusingly.

"You didn't hear, Raul couldn't find anything on that guy, no noble family knows such a man, he was more than likely a fraud!" The man suddenly put on a cold expression.

"Haha, what an idiot, he basically gave us a power fruit for free!" The man couldn't stop laughing and spitting! "I heard they give you abilities, what can this fruit do?" The spitting leader stopped laughing suddenly and asked.

"Hmm, from what I heard, this fruit gives you the ability to change into an animal. The animal from what I heard was a Komodo Dragon, it was dark green and scaley fruit from what I could see." The man had seen the fruit but only a glimpse of it but that was enough.

"Damn, how come you know so much? I don't know any of this and we have the same ranks!" The man was spitting like a water hose which caused the man to back away quickly.

"Connections!" That's all he said before turning away.

Rein sighed, he had been found out less than a day, these people didn't play about their money. His choice to rob this place was a good one indeed. After waiting in the shadows for about an hour, he heard the news.

"The Power Fruit was just sold, it was sold for 305 Million Berries! Put the money into the vault, immediately! The boss wants to set a trap for that man in white when he comes back tomorrow so have your weapons ready first thing tomorrow!" The man that walked in looked far more intimidating than the two leaders before.

The two fearfully replied and called the workers over to load the money up. The man from before left soon after to handle other business. "That man from today is a dead man for sure, how dare he trick us by acting like a noble!?" Two other men were furious, these were the two bodyguards from earlier that stopped Rein at the door.

They really wish to crush Rein into bone powder right about now, they couldn't wait to get their hands on him when the time came. They were working for the two leaders, the spitter and the know it all.

"What the...A..H!" The man leader tried to scream but was suddenly turned into an ice sculpture!

"We're under atta~~!" Within 10 seconds, everyone was turned into a block of ice. Rein didn't use any crazy ice force on them, so no one died. Some might end up losing a limb or so but not the workers, he used really weak stuff on them.

Rein rushed the vault and started to rob it clean, Diamond, Pearls, Gold bars, you name it, it was all here! Rein eyes turned into dollar signs and stuffed everything into his storage before leaving. "Hahaha, I might be able to buy a small island with this fortune!" Rein couldn't stop laughing as he left the auction house. It was time to immediately leave this city, he assassinated Stelly and robbed an auction clean,

"The marines might come to investigate with a dead noble on their hands." This would definitely be so with the way Stelly was killed. It could also trace back to the auction house since they were also frozen by the same force.

"It was worth it, haha!" Rein laughed as he flew away back to Mt. Corvo.
