I'm at the top of One Piece

"I'm not staying here forever, and neither are you. We'll be leaving in a few days."

Karp stopped laughing and looked at Slab and Ah Ying.

“That’s right. Then I’ll leave Luffy to you. I’ll have someone buy all the medicinal herbs today, and I’ll bring Mather over tomorrow.”

"Okay, then you go ahead and do your thing."

Slab knew that every time Karp came back in recent years, he would go to Mount Colbo behind the mountain, which must be something important.

With a wave of his hand, Garp led Moses away, while Slab and Aying, each holding a baby, watched the two walk away.

"Dad, we owe it all to Uncle Garp this time, otherwise I can't believe Arthur would have been in trouble."

"Yes, I owe that old guy a huge favor again, so we have no choice but to raise little Luffy properly for him."

"Yes, I will raise Luffy as my own son."

……

"Sir, shall we go see Ace now?"

Mercer and Garp were walking down the street. "Where is he?"

Garp scratched his head somewhat awkwardly, "Let's go to the warship first and give the prescription to Bogart, then I'll take you to find Ace."

A short while later, Garp gave the prescription to Bogart on the warship. Bogart was very happy about this, because Garp hadn't punished him for misleading Messe on the way there. He had been a little uneasy, but now he could use this opportunity to "make amends".

Ignoring Bogart's joy, Karp simply smiled and said, "Now that the internal affairs are settled, let bygones be bygones. The expenses will be covered by my commission."

"Let's buy a hundred sets first."

Bogart patted his chest and laughed:

"Don't worry, you can rest assured that I'll handle things well."

Messer smiled, picked up his packed bag, and looked at Garp, saying, "Master, let's go. I also want to see him soon."

Moses was quite curious about his younger brother, whom he hadn't seen since birth, and wondered how old he was now.

I suppose they're just like me.

After all, they were born on the same day.

I wonder what her personality is like now.

Karp smiled and took the luggage from Messer's hands. "Let's go."

Under Bogart's watchful eye, the two disembarked from the warship and followed a small path up the mountain.

……

In the lush jungle, occasional, unidentified roars could be heard.

Capra led Moses through the forest, and seeing Moses looking around curiously, he chuckled and said:

"How is it? Isn't it beautiful? It's a completely different world from Drum Island. It's not cold at all, right?"

As they ventured deeper into the mountains, the surrounding trees grew taller, and the fragrance of grass and trees in the air became even stronger.

Mercer couldn't help but relax, carefully sensing the subtle connection between himself and the natural environment.

His Observation Haki surged around him as he sensed the various auras within the forest.

Breaking free from Garp's grasp, Messer walked with Garp, his breathing rising and falling, his aura gradually changing, as if slowly blending into the surrounding environment.

He exuded an ethereal and tranquil atmosphere.

Garp's eyes widened suddenly, his mouth gaped open as if a balloon could fit inside, and he stared at Mercer as if he were about to disappear from his sight.

The aura emanating from him seemed to assimilate with the surrounding environment, which was extremely eerie.

"Devil Fruit ability?"

"No, no, Moses is not."

Mercer savored the "breathing" of the surrounding trees, controlling his own breathing, constantly approaching and assimilating, imagining himself as a tree, a leaf, freely rooted in the earth, growing wildly and freely.

Relax your body and let nature take its course.

By constantly aligning one's own breathing frequency and breath with the frequency perceived around one's surroundings.

Keep moving forward.

After a long while, Moses broke free from that intimate and natural state of mind, withdrew his Observation Haki, and a smile appeared on his lips.

He looked at Garp beside him.

"What's wrong, sir?"

Garp blinked and looked closely at Mercer, the feeling that he was about to disappear vanished.

"What were you doing just now?"

Mercer chuckled, “A very ordinary way of breathing, a way to regulate one’s body and mind.”

Mercer wasn't lying; this breathing method evolved from breathing itself.

Garp was speechless. "Do you think Grandpa's stupid? If I could breathe like that, why couldn't I?"

Mercer chuckled and said, "That's because you're too stupid, sir."

Kap was so angry that he glared and his beard bristled, feeling his fists harden.

Just as they were about to make a move.

But then he heard what Moses said.

"Grandpa, do you want to learn? If you do, I'll teach you."

Karp's eyes widened, he opened his mouth and sighed: "If you don't want to learn, it's probably not something you did all by yourself. That woman, Doriel, must have played a part in it."

As Garp continued walking forward, Moses looked at him in surprise:

“Indeed, this is a special breathing method that Doctor Doriel discovered from my breathing.”

Karp's eyes revealed his understanding.

This breathing technique, which can be described as a special inheritance, must have taken a lot of blood and sweat to learn. I can't just steal it from Messer. If I did that, it would be a taboo.

Obviously, Garp is not that kind of person.

Seeing Garp's expression, Moses understood and said with a smile:

"Although the breathing technique was compiled by Physician Doriel, I am the first in line and have the right to teach it to others."

"Dolly the doctor won't interfere in this matter, nor will she care. I asked her, and she said it's up to me."

"As long as you can promise not to tell anyone, Grandpa, I'll teach you."

Garp looked at Mercer suspiciously. "Really? You're not lying to me?"

"Believe it or not, learn it or not, I didn't lie. If you don't learn it, it's your loss, not mine. I'll just consider myself a good Samaritan."

Garp's eye twitched, and his teeth clenched so tightly they made a grinding sound.

"You little brat, how dare you call me a stupid donkey?"

“I didn’t say that, I didn’t, you found out yourself.”

"Aaaaah, you brat, you still say you didn't say it."

Seeing Garp jumping up and down in anger, Messer knew he couldn't say anything more, or he'd get beaten up, which wouldn't be good.

then.

"Sir, do you want to learn?"

Moses asked again.

Garp sighed sullenly, "Go ahead and learn it. I promise you, I will never tell anyone without your permission."

"Well!"

The two walked and talked, with Moses talking and Karp asking questions.

To make it easier to teach him, Messer also had Karp use his Observation Haki to carefully observe his breathing rate.

As Karp came to his senses, his breathing began to change.

From shallow to deep.

The instinct to breathe, which used to be natural, is slowly changing.

Messer was also using Observation Haki to observe the changes inside Garp's body. At first, it seemed like something was blocking the way, making it difficult to observe. However, after Messer suggested it, Garp cooperated, and everything became easier.

After a while,

Seeing that Garp had already mastered the basics of breathing, Moses laughed and said, "Not bad, not bad, you're really smart."

Karp immediately beamed with joy, patting his chest with hearty laughter:

"Of course! Don't you know who I am? If I can be your master, how could I be anything less?"

Mercer looked at Garp with a strange expression and said indifferently, "Shameless."

Relying on his supposed control over his body after regaining his life, he arrogantly claimed to be smart, saying he was just talking and he actually agreed. How shameless.

Garp twitched his face.

Just pretend you didn't hear it.

At this moment, Moses asked, "Master, why was it so difficult for my Observation Haki to penetrate your body just now? Something was resisting it. What was that?"

Sure enough, the next moment Garp said:

"Hey ha~, want to know? Well, I'll tell you then. It's also a kind of Haki, called Armament Haki. It can be used as an invisible armor and can also resist the invasion of foreign objects."

"Impressive, right?"

Moses nodded.

"Hmm, that's impressive, but how do we unleash its full potential?"

Garp glanced at Messer, rubbing his chin. "You're still a bit too young. Pushing it too hard too early won't do your body any good. Wait a few years."

"It's not good for your health?" Mercer asked curiously. "Is it related to vitality? Or perhaps your own energy, blood and qi?"

Karp's expression stiffened, and he glanced helplessly at Messer. "Did Doriel tell you? That woman tells you everything."
