Power System of the 'World'

Shimotsuki Village Dock.

A handsome young man with a straw hat was laying there bathing in the light of the morning sun, as people pass by they would shot him weird glances, most of them was pitying this homeless boy! because this guy was sleeping there from yesterday. there were a lot of people that invited him to their homes, but he kept being unmoved!

"They are late! I hope kuina wasn't affected by Zoro's Misdirection!"

Two hours later, a green-haired young man and dark blue-haired girl made their way towards him while having a weird look too. feeling their arriving, Luffy stand up!

"Let's go" as he said that he kept moving toward the end of the port, Zoro and kuina followed him, while in a distant place, Koushirou was standing there, his eyes kept flashing!

The reason why he didn't want to leave the dojo, was all for the 'wellbeing' of his daughter, now that she took the sea, it seems, he need to leave as well, his little girl seems to grow up without even him noticing it.

"Monkey D heh? hahaha, interesting!" as he said that, he suddenly faded in the crowd.

"Excuse me Captain, where is our ship?" said Zoro while looking around.

"There is none"

"What? hm, we are pirates after all! so it seems we need to steal one, right Captain!" said kuina with a gleam in her eyes. this girl somehow is dangerous.

"No, we don't need one currently, we will steal one later!" said Luffy

Zoro was the only reasonable and upright person here it seems, as he repeatedly showed his disapproval!

"As I was taking my nap, I was examining the nearby islands, and I found that one of our crew seems to be in danger, so we are moving fast! and it happens that I need to teach you something about the sword and the power in this world!"

"What?! nearby islands! how could you do that?!" said Zoro

"He is bragging!" Kuina didn't believe him. but the truth, is that if he concentrate, he could cover 1/4 of the one piece world! he is a cultivator and not a 'Kenbunshoku haki user'

As they were cursing him, he took a step and stopped above the sea, while turning his head towards the duo "hurry up, jump we will be running to the next Island, it will be both a training for you, and I will tell you more about the world, so you could understand how pitifully weak you are!

This time they were shocked! a devil fruit user who isn't afraid of sea water?! that's unheard of!

As they jump from the dock, they were surprised! as under their feet seems to be a space that cut them from seawater.

"Let's hurry!" Luffy started running while the duo followed him.

"Power system of the world are divided to two types:

Type 1 :

Devils fruits : and that's also divided in three types

1 - Paramecia : It give the users a power that can affect their body, manipulate the environment, or produce substances.

2 - Logia : Characterized by giving its user the ability to become, create, and control an element or force of nature, a common trait among Logia Devil Fruit powers is that of intangibility, and the ability to reform one's elemental body if its structure is disrupted in any way, often from physical attacks. if you meet someone with this power in the sea with your current power, you are dead! you can't cut it because you can't cut a nature law or an element. they are unkillable and count as overlords in the first part of Grand line, unless they face a user with a contradicting element or if you use some strategy!

3 - Zoan : It allows the user to transform into another species and inter-species hybrid forms at will, and are especially effective in close combat."

"Gulp! Can't cut?!" Zoro was shocked! if he can't cut him, then he won't stand chance! for the first time Zoro understand how weak he is.

"What about the second type system power, you said they are overlord in the first part of grand line, but what about the second?" Kuina said with a tremor in her voice, but as expected she is a smart one.

Luffy turned his head, while looking at the white faces of his new crew members, and he couldn't help but smirk!

"The second power system is the counterattack of Devil Fruit users, with it you can cut while completely ignore the elemental body, it even increase the power of your attack tenfolds if not hundreds depending on your mastery."

"I can cut it after all!" said Zoro with face full of hope, he now understand that if he wanted to live in the sea, and become stronger! the second system was the most reliable for him. Kuina simply shut her mind while looking towards the back of Luffy while waiting for him to continue.

"The second system of Power called 'Haki' and this is a mysterious power that is found in every living being in the world. It is not that different from the typical senses. However, most people do not notice it or fail to awaken it. Broadly speaking, there are two types of Haki available to everyone, given the proper training; however, there is a third type that only a certain group of "chosen ones" are said to possess, but that's not important for the both of you right now, what you need to grasp is the ability to sense spiritual energy (Kenbunshoku) and use life force (Busoshoku) to coat a part or the entirety of your body.

Kenbunshoku : if mastered could even predict your opponent attacks, sometimes, you can even glimpse at the future and it's very important to a swordsman.

Busoshoku : allows the user to use their spirit to create, in essence, an invisible armor around themselves. Notably, this form of Haki can be used to injure Logia Devil fruit users, also amplified your attacks damage.

Around our journey, we will encounter a lot of strong opponents, so you need to use them as sharpening stone, along with my tutoring, you will awaken this natural powers in no time."

Zoro and Kuina were fascinated! they were really a frog in a well!

Luffy kept tutoring them the way to train 'Haki' the way Garp teached him while they make their way towards 'Organ Islands'

Suddenly Luffy said something that surprised the duo again "Actually there is a third power system, but this one is universal, multiversal and omniversal!"

Even though they didn't understand his words, they could tell that this 'Power system' was more stronger than 'Haki' and 'Devil Fruits', and they couldn't help but show a hopeful expression while watching his back.

"Hehehe, but you need first to master the 'Haki' Zoro! as for Kuina," he stopped here, to continue while smirking with a shameless expression " She may get the benefits sooner! work hard Zoro!"

Sexual cultivation using an Origin Law such as 'Yin-Yang' would change every woman that slept with him! he even started having the thought to visit Amazon Lily and build his Army.

The both of them didn't understand, but as Kuina saw his expression, she know that it was no good!

Slowly but surely, they made their way through the islands region, approaching Orange Town, from far away, they could see that the whole town was destroyed! debris everywhere, and they couldn't spot any human in the town.

As for Luffy, he was smiling happily! it seems Nami didn't listen to his advice, he could clearly saw that buggy was caging her inside a steel cage, while pointing a canon to her! saving her now will make it easy to steal her heart!
