One Piece: Becoming Stronger and Bigger by Becoming a Seven Warlord of the Sea

"Really?"

"Of course, after all, what reason do I have to stop a man from going to sea for his dream?" Xia Tian raised the corner of his mouth slightly, revealing a smile.

"Luffy, come here," Xia Tian then waved his hand, and Luffy came over with a curious look on his face. He just heard that Xia Tian was going to teach Ace a very powerful move.

"Pop!" Xia Tian flicked Luffy's head.

"Ah, it hurts! Xia Tian, ​​what are you doing! Why do I feel pain even though I'm rubber?"

Luffy covered his head and looked at Xia Tian in confusion and anger.

"Hahaha, this is a testimony of my love as a brother, Luffy!"

Luffy: "(*￣rǒ￣)(ー_ー)!!" I don't believe you!

"Let's get back to the point, Ace, as you just saw, I flicked Luffy's head, and the means of causing him pain is called domineering by the people in the New World."

"The so-called domineering is a kind of power hidden in the human body, momentum, pressure, deterrence, which is something that everyone is born with. However, many people have never noticed it in their lives or cannot use it even if they know it. They end their lives in a hurry and believe it firmly. This is a kind of strength."

As soon as the voice fell, Xia Tian took out a black eye mask from his pocket and put it on, and then said.

"Ace, come on, attack me hard!"

"Are you sure?!"

"Of course! Next, watch carefully and learn well."

"Swish!"

Ace waved the water pipe in his hand and swung it down vigorously. At this time, Xia Tian's body sank slightly by ten centimeters and then moved to the right to avoid the attack in advance. At the same time, he opened his lips and said: "Ace, you swing the water pipe to attack my head from the upper right to the lower left."

"Swish! Swish! Swish!"

Seeing Xia Tian dodging in advance and saying the attack method, Ace continued to swing his weapon quickly, again and again, and finally stopped after swinging more than 20 times in a row. Ace didn't hit once, and looked at Xia Tian with eager eyes.

Ace and Luffy's eyes were full of the desire to learn the word °˖✧︎◝︎(⁰▿︎⁰)◜︎✧︎˖°.

"There are two types of Haki, Observation Haki and Armament Haki. This ability to feel the strong breath of the opponent is Observation Haki. If you improve this ability, you can sense the number and position of enemies that are not in your sight, and even predict the opponent's attack in advance, just like just now. When Observation Haki is raised to the extreme, it is said that you can see short future events."

"The other is Armament Haki, which is like putting on an invisible hard armor for us to improve our own attack methods. Another function of Armament Haki is to deal with Devil Fruit users like Luffy. In addition to relying on weak points to attack, Armament Haki is the only means to deal with Devil Fruit abilities. Whether it is animal-type, superhuman-type or even natural-type Devil Fruit, it can attack entities."

"The three admirals with the highest combat power in the Navy Headquarters are natural-type Devil Fruit users. If they don't have Armament Haki, they will become lambs to be slaughtered and have no resistance."

"In addition to these two common Haki, there is also a special Haki that is one in a million, the Domineering Haki. Now the top strong men on the sea in the New World have this Haki, and Pirate King Roger also has this ability."

Xia Tian paused for a moment when he said this. Sure enough, Ace looked a little angry and unwilling. His little hand was clenched tightly, and his nails were embedded in the flesh without knowing it.

"Sure enough, Pirate King Roger also has Domineering Haki, Si Guy, I don't know if I will have it in the future."

When Luffy heard Xia Tian talking about Roger, his face was very excited, just like when Bartolomeo met Luffy later. This is the idol that Luffy has always wanted to be.

"Hahaha, maybe both of you have Conqueror Haki."

Xia Tian said when he heard Luffy muttering to himself.

"Then, the Haki teaching begins! First of all, the first step is to calm down and feel the power in your body..."

"Inhale, exhale, inhale, exhale~"

Learning about the power of Haki, Luffy and Ace began to learn very seriously, especially after learning that there are so many powerful monsters in the New World, the two worked even harder.

As for whether teaching Haki in advance will affect the development of the plot later and cause a butterfly effect, Xia Tian doesn't care, because compared with these two people, Xia Tian is the biggest variable.

After all, what is the point of being a traverser if the traverser doesn't change the world? ¯\_(ツ)_/¯

Time flies, like a white horse passing by. In a blink of an eye, Xia Tian has been here for half a month. Luffy and Ace are indeed geniuses. They have mastered and can use Haki in such a short time.

Then, after mastering Haki,Ace beat Luffy again, and the "fist of love" hit Luffy's head, and Luffy immediately roared with his teeth bared.

"Damn Ace, I will definitely beat you next time!"

"Hehe, Luffy, you couldn't beat me before, but now I have mastered the domineering, and I will not lose, hahaha!"

The two brothers lay on the grass, not forgetting to bicker, and then happy laughter came, resounding throughout the forest.

"Ah~"

"What's wrong, Luffy?"

Hearing Luffy sigh, Xia Tian asked puzzledly.

"It's a pity that Sabo is gone, otherwise...ᵟຶᴖ ᵟຶ"

"Don't be sad, Luffy, maybe Sabo is still alive, after all, you didn't see the body at the beginning, right? When you go out to sea to travel around the world for a week, you may meet him on your journey to become the Pirate King." Xia Tian persuaded, but did not tell him about Sabo's affairs in the Revolutionary Army. The meeting of the three brothers needed a better opportunity and time.

"Hehe, I will definitely travel around the world and find the great treasure. I want to be the man of the Pirate King. ૧(●´৺`●)૭".

When it comes to the Pirate King, Luffy is very excited. He jumps up from the ground with a carp jump, looks at the boundless sea with a smile, and declares loudly. Just as in response to Luffy's bold words, the sea in front of him is turbulent, and the waves suddenly roll up, one wave higher than the other.

"Tsk! Boring dream", Ace said with a complicated look on his face. He didn't understand what's good about the Pirate King.

"Humph, ╭(╯^╰)╮The Pirate King is the freest man in the world, very handsome, okay", Luffy pouted and retorted unconvincedly.

"Hahahahaha!"

The familiar scene appeared in front of him, and Xia Tian laughed happily.

Three minutes later, Luffy was lying on the ground sleeping soundly, with his snot bubbles expanding and contracting wantonly.

"Ace, don't care about other people's evaluation, Pirate King! Maybe you are not as evil as people say. When you go out to sea, experience it yourself. Maybe, after experiencing more things, many knots will be untied."

On the hillside, the breeze blows on the face, Xia Tian and Ace stand side by side. During this period of time, Luffy accidentally revealed Ace's identity. Although Xia Tian already knew it, he still pretended to be surprised.

Now, the two of them had a simple exchange about Pirate King Roger.

Regarding the evaluation of Pirate King Roger, there are mixed good and bad. He opened the Age of Discovery with one sentence. Countless young people became pirate pupae to obtain the great secret treasure and entered the new world. They burned, killed, plundered, and committed all kinds of evil along the way, which caused headaches for the navy. Ordinary people were displaced. This is the bad thing.

On the other hand, Roger achieved unprecedented success, reaching the final island of Raftel, obtaining the great secret treasure and knowing that the world government tried hard to hide the blank history of a hundred years. The arrival of the Age of Discovery promoted the pace of the new era. A group of young people who dared to resist stood up and exposed the darkness of the Celestial Dragons, making a huge foreshadowing and beginning for the final peace and equality of the new world, which was a milestone. Therefore, Xia Tian did not make a single judgment, but explained his views to Ace from the perspective of God. The rest was Ace's own decision, and others could not interfere.
