Uchiha Puppet Master, Starting from One Piece

"Boy, I heard you're going to cultivate on a remote island in the windless zone?"

Green Pepper's voice was loud and clear, making people's eardrums tingle slightly. He walked up to Bai Yu and looked him up and down.

"The power of Haki isn't something you can master just through training; you also need real combat experience. Those sea kings are the perfect opponents. But remember, the essence of Haki lies in the heart. If your heart isn't strong, your Haki won't solidify. When you encounter danger, don't even think about backing down. If you back down even once, you'll never reach the top in your entire life. Sigh..."

Upon hearing this, Bai Yu's heart stirred slightly. He knew that what Qingjiao said was true. Both Armament Haki and Observation Haki required an extremely firm will as their support.

For example, Gecko Moria lost his willpower, so he couldn't even use Haki anymore.

He bowed slightly to the green pepper and said, "Thank you for your guidance, Dongliang. Bai Yu has learned a lot."

Green Pepper grinned, raised his hand and patted Bai Yu's shoulder with such force that Bai Yu's shoulder slumped slightly: "Good lad, you've got guts! I'm rooting for you. If you manage to come back alive from that island, remember to come see us and let me see how you've grown."

"Next time we come, if we're more assertive, Brother Cai, you'd better prepare some good wine."

Cai Yi chuckled upon hearing this: "Of course, of course. As long as you come, you can choose any wine cellar from the Babao Navy."

Ranju smiled, her eyes crinkling, as she twirled the wine gourd between her fingers before carefully fastening it back to her waist.

As the sun gradually set in the west, it cast long, long shadows of the four people.

Cai Yi and Qingjiao stood at the dock entrance, watching Bai Yu and the other three turn around and step onto the boat docked at the dock. The sails were billowed by the wind, making a rustling sound.

"Bon Voyage!"

"Take care of yourself!"

Bai Yu stood at the bow of the ship, turned around and waved to the two of them, his three-tomoe Sharingan glowing faintly red in the setting sun.

Rangiku leaned against the ship's railing, took another sip of sake, and gestured for the two men at the castle gate to drink. Robin stood beside him, her gaze fixed on the boundless sea in the distance, a searching light gleaming in her eyes.

The small boat gradually sailed away from the dock, heading towards the calm zone. The two figures at the city gate grew smaller and smaller in sight, eventually turning into two blurry black dots.

"Does the old man really think highly of them?"

"I'm paving the way for you, Cai Yi. Let me tell you, your strength is still insufficient to hold onto Dongliang's position. I've already found you Erbao's naval forces, Dongliang's daughter, and you..."

"Grandpa...I..."

After sailing for several days, the sea ahead gradually became calm and still, without even a breath of wind. The color of the seawater also changed from azure to a deep, dark green, exuding a chilling aura.

"We've arrived. We've entered the Calm Belt and are preparing to use Mana to advance."

Bai Yu said in a low voice, his eyes scanning the surrounding sea surface warily.

Just then, the calm sea surface suddenly began to shake violently, and a huge black shadow slowly rose from the water. It was a sea king that was more than tens of meters long. Its head was like a small mountain, its mouth was open, revealing a dense array of sharp teeth, and a foul stench wafted over.

Connor, far from being afraid, jumped up excitedly: "What a big fish! Baiyu caught it! I want to eat a big fish!"

As she spoke, she tried to break free from Bai Yu's hand and lunged at the sea king.

"Don't rush."

Uchiha Hakuha grabbed her, a sharp glint in his eyes.

"Good luck, everyone. This is the first lesson: use your Observation Haki to sense its movements."

He took a deep breath, slowly closed his eyes, and cleared his mind of all distractions. In an instant, everything around him became clear: the sound of the flowing sea, the beating of the sea king's heart, and even the subtle rustling of its scales rubbing together, all flooded his mind like a tide.

"Try to feel it."

Bai Yu's voice was deep and steady.

"Feel its presence, sense its movements, and then anticipate its attack."

Robin and Rangiku followed Shiraha's example and closed their eyes. At first, they could only hear the sound of the waves, but gradually, as their minds settled, the movements hidden beneath the sea began to emerge.

Just then, the sea king suddenly swung its tail and lashed out at the ship!

"Watch out!" Rangiku instinctively drew her sword, but Shiraha raised his hand to stop her.

Without hesitation, Bai Yu turned the rudder, and the ship, powered by Mana Energy, sped off to the left like an arrow.

Almost simultaneously, the sea king's tail lashed out at the spot where they had just been standing, creating a towering wave.

"What an amazing fish!"

Connor clapped his hands excitedly, his little face full of joy.

In the days that followed, the four of them settled down in the Calm Belt.

Bai Yu was responsible for guiding the three in training Haki and Armament Haki, starting with the simplest techniques.

Robin has a very high level of comprehension. Although she is physically weak, she has an extremely strong sense of focus.

She used the patience she had for studying historical texts on cultivating domineering aura.

Rangiku, however, is the most talented, possessing the Soul King's fingernails. With a complete soul, Rangiku took a different path, needing to imbue her Snowfall Blade with Armament Haki.

The training of Observation Haki takes place in the dead of night, when the Sea Kings are most active during the windless nights.

Even at the edge of the cliff, you can feel the presence of sea kings.

The four of them sat on the rocks by the sea, closed their eyes, and sensed the presence of hundreds of sea kings around them.

At first, the chaotic atmosphere flooded their minds like a tide, making them dizzy and even unable to sleep all night.

But gradually, they began to learn to filter, to discard the useless auras, and to focus only on the most dangerous ones.

Days passed by...

On this day, as the sun set, it dyed half of the sea red.

Bai Yu stood on the reef, looking at the three people not far away.

Robin had her eyes closed, sensing the movement of a lurking sea king underwater. The corners of her mouth were slightly upturned, clearly indicating that she had completely pinpointed its location.

Bai Yu nodded in satisfaction.

During this time, all three of them have mastered both Armament Haki and Observation Haki.

Robin's Observation Haki is the most acute, and Rangiku's Armament Haki can adhere to the blade, increasing its power; only Connor's gains are not high, as Armament Haki provides too little enhancement for a dragon.

"Let's go get some barbecue..."

Uchiha Hakuba and his group walked deeper into the dense forest, using their Observation Haki to capture all the movements around them.

However, at first, his Observation Haki was merely a training exercise to develop his instincts, while the ferocious beasts along the way had already fallen haphazardly in front of Bai Yu.

His Conqueror's Haki is exceptionally gifted. The claim that a sixteen-year-old with three tomoe is just an ordinary Uchiha is indeed a joke, since transmigrators usually have the Mangekyou Sharingan before the age of ten...

Just before he stepped out of the forest, a saber-toothed tiger nearly ten meters long suddenly pounced out from behind a tree. Its muscles bulged beneath its tan fur, and its sharp fangs gleamed coldly. The force of the attack caused the leaves to rustle.

This ferocious beast is the overlord of the isolated island forest. It usually dares to hunt down even sea monster cubs that are resting on the shore and ready to go ashore. But now it sees Bai Yu as its prey.

But as soon as it took off, it fainted, fell to the ground, and kicked up a huge cloud of dust.

Excuse me...

Bai Yu's voice was indifferent as he stepped over the unconscious body of the saber-toothed tiger.
