Chapter 219: The Peak of Armament Haki! The Resonance of the Sharingan and Ryuo
Tatsuya reached out and pushed open the incredibly heavy steel door in front of him.
Accompanied by the dull grinding sound of the door hinges, he followed a steep flight of stone stairs leading downwards, arriving at a vast and empty training ground deep beneath Baltigo.
As soon as he stepped inside, an aura of murderous intent and wildness rushed towards him.
With the help of the torches burning on the surrounding walls, one could clearly see that the hard rock walls were covered with various terrifying claw marks and bottomless slash marks.
Those marks crisscrossed, as if silently displaying the formidable strength of the owner of this place.
In the center of the training ground, Sabo, bare-chested, was currently supporting himself with one hand on the ground, performing high-intensity one-finger push-ups that were unimaginable to ordinary people.
Sweat slid down his sturdy, well-proportioned, and scar-covered muscle lines, dripping onto the dry stone floor.
Hearing the sound of the door opening, Sabo immediately stopped his movements and stood up with a nimble flip.
He casually grabbed a towel draped nearby and wiped the sweat from his face.
When he saw that the person who arrived was Tatsuya, his azure eyes instantly ignited with fanatical fighting intent.
"You've come, Crimson Lotus."
Sabo grinned at Tatsuya, revealing two rows of white teeth.
While loosening his wrists, he said with a serious tone:
"Although you used that incredible ability to help me recover the memories most important to me, and counting it up, I owe you my life."
Sabo changed the subject, his eyes becoming incredibly sharp:
"However, in the upcoming Haki special training, as the Chief of Staff of the Revolutionary Army, I will absolutely not hold back in the slightest!
"If you, Vice Captain, only have the level boasted about in the newspapers, you might really get killed by me!"
Facing this pre-battle declaration that was half warning and half provocation, Tatsuya curled his lips into a calm smile and responded indifferently:
"Wanting to kill me, even for you, might be a bit difficult."
The tension between the two was on the verge of breaking out, but they did not immediately make a move.
"Follow me."
Sabo turned around and led Tatsuya to a huge piece of specially made refined steel rock at the edge of the training ground.
This rock's hardness far exceeded ordinary steel and was specifically used to test destructive power.
"To master internal destruction, first you must understand its essence."
Sabo took a deep breath and began to explain the core principle of high-level Armament Haki to Tatsuya:
"The vast majority of people's understanding of Armament Haki stops at simply 'hardening' their bodies or weapons."
"Or 'coating' Haki on attacks to increase power and defense."
"But that is only the most basic application."
Sabo extended his right hand, his five fingers slightly curled:
"True high-level Armament Haki is called 'Ryuo' in Wano Country.
"As the name implies, it requires you to no longer confine Haki tightly to the surface of your body.
"Instead, you must let Haki flow freely inside and outside your body like a stream of water!"
To help Tatsuya understand more intuitively, Sabo's right hand instantly transformed into his signature "Dragon Claw" stance.
A layer of pitch-black, deep Armament Haki, like tangible ink, lingered at his fingertips.
He did not explode with storm-like power to strike the rock as he usually did.
Instead, with very gentle movements, he lightly pressed the hand covered in Haki onto the surface of the huge refined steel rock.
"Watch closely."
Accompanied by Sabo's low shout.
"Bang!"
An extremely dull explosion sounded from inside the rock.
Incredibly, the surface of that huge refined steel rock was completely intact, not even a tiny crack appeared.
However, after a breeze blew by.
That huge rock, which seemed indestructible, instantly turned into countless tiny powders and dust!
Those powders, like a sandcastle that had lost its support, collapsed all over the ground and drifted away with the wind.
Witnessing this terrifying destructive power that completely ignored external defense with his own eyes.
Tatsuya's deep black eyes suddenly narrowed, and a trace of shock flashed in them.
"Did you understand?"
Sabo withdrew his hand and turned to look at Tatsuya:
"High-level techniques like Ryuo cannot be learned just by relying on verbal instruction and rote memorization.
"To master it, you can only personally feel the 'flow' of Haki in extreme actual combat on the edge of life and death!"
"Come on!"
Before his voice fell, Sabo suddenly stepped out with "Soru" from the Rokushiki.
His figure instantly turned into a blurred afterimage and disappeared from the spot.
The next second, he had already appeared above Tatsuya's head.
Sabo swung the high-density steel pipe, also wrapped in Ryuo, with both hands, bringing a violent whistling sound that tore through the air as he smashed it down!
Facing this sudden sense of oppression.
Tatsuya not only did not choose to retreat to avoid the edge, but instead exerted force in his legs and met it head-on instead of retreating!
"Clang!"
At the moment of the sprint, Tatsuya's eyes underwent an earth-shattering change.
The originally pure black pupils turned into a sea of scarlet, and three pitch-black tomoe spun crazily in the blood-colored eyes, emitting a chilling mental fluctuation.
Three-Tomoe Sharingan, activate!
The Sharingan's most acclaimed powerful insight not only could easily see through the enemy's taijutsu movements and subtle flaws.
In this pirate world full of Haki, it was developed by Tatsuya's body into a brand-new function that was almost abnormal.
See through "Haki flow"!
In Tatsuya's field of vision covered by the scarlet filter.
Inside Sabo's body and on that steel pipe.
The originally invisible and intangible flow trajectory of high-level Armament Haki was now like the brightest star trails in the night sky, fully captured by Tatsuya.
How that Haki gathered from the dantian, how it flowed along the meridians to the arm, and finally how it wrapped around the surface of the weapon and maintained a "flowing" state...
All of this, under the insight of the Sharingan, was displayed before him without reservation!
"So that's how it is..." Tatsuya realized in his heart.
However, although the Sharingan allowed him to clearly understand the trajectory and principle of Ryuo.
But "understanding" and "the body being able to learn to guide it" were two completely different things.
"Clang! Clang! Clang!"
In the first few hundred rounds of fierce confrontation.
Tatsuya could still only use the most basic Armament Haki hardening for defense and attack.
This rigid hardening, in front of Sabo's nimble and destructive Ryuo, was completely in a passive situation of being unilaterally suppressed.
Amidst the splashing sparks, the black blade shusui in Tatsuya's hand was repeatedly shaken away by the hidden force erupting from within, making his hand numb.
The powerful counter-shock force even transmitted through the blade into his body, causing a few wisps of blood to overflow from the corner of Tatsuya's mouth.
But as the battle continued, what made Sabo, who was attacking wildly, feel a chill of horror was...
This Vice Captain of the Straw Hat Pirates, known to the world as the "Worst Generation".
His learning ability was simply like a terrifying abyss that was never tired!
Every time he was knocked back by the steel pipe containing Ryuo, Tatsuya's eyes would become a little brighter.
When he swung his blade to meet the attack next time, the Armament Haki attached to the black blade shusui would undergo a tiny but fatal subtle change.
That originally dead Haki was becoming more and more active at an astonishing speed visible to the naked eye.
Getting closer and closer to the "flowing" state that Sabo displayed!
"This guy... could he be directly copying my Haki usage method in battle?!"
Sabo was shocked, and his offensive became even more fierce.
After a fierce collision, Tatsuya was forced by Sabo into a desperate situation in a corner of the underground training ground.
There was no way to retreat!
Facing the fatal blow from Sabo that struck again, a trace of madness flashed in Tatsuya's eyes.
He did not choose to use the Body Flicker Technique to dodge.
Instead, he took a deep breath and forcibly injected the violent Lightning Release Chakra in his body and the Ryuo Haki he had just caught a glimpse of in actual combat into the black blade shusui in his hand without reservation!
"Crackle—!"
Accompanied by a violent thunderous sound like a thousand birds chirping.
A shocking scene occurred.
On the dark red blade of the black blade shusui, not only was it wrapped in deep blue high-voltage lightning.
But also on the periphery of the blade, a layer of dark red Haki coating that constantly flowed like cherry blossom petals emerged!
"Ah!!!"
Tatsuya shouted, gripping the hilt with both hands.
"Boom————!!!"
Two terrifying forces, both reaching the top level of this sea, erupted in this enclosed underground space!
The deafening loud noise seemed to want to tear a black hole in the underground.
Black-red Haki lightning accompanied by deep blue thunder, like countless furious poisonous snakes, raged and traveled wildly in the vast underground hall, blowing the surrounding rock walls to pieces.
Even this underground training ground, specially reinforced by the Revolutionary Army, its sturdy ceiling began to be unable to withstand this terrifying shockwave, and began to drop large pieces of rubble crazily.
This strong vibration even penetrated the thick strata and was clearly transmitted to the desolate ground of Baltigo.
For a long time, the sky-filling smoke and dust finally dispersed slowly under the blowing of the strong wind.
In the center of the training ground, Tatsuya and Sabo each slid back dozens of steps before barely stabilizing their figures.
Sabo's chest heaved violently.
He lowered his head and took a look at his right arm, which was trembling slightly and even somewhat charred by the lightning.
Subsequently, he raised his head and looked at the opposite side with a complex gaze as if looking at a monster.
Dozens of meters away on the opposite side, Tatsuya was leaning on the black blade shusui with one hand, also panting heavily.
The black shirt on his body was already tattered, and he was injured in many places.
But the scarlet Sharingan had already faded, and in his eyes, which had returned to pure black, they were full of joyful and confident smiles.
Looking at this man who had undergone a transformation in just one battle.
A turbulent wave that could not be calmed surged in Sabo's heart:
"Actually... in just a few hours of high-intensity actual combat, he forcibly touched the threshold of internal destruction..."
Sabo swallowed a mouthful of saliva and muttered to himself in his heart:
"Luffy, that idiot little brother... what kind of terrifying monster did you find on this sea to be your Vice Captain!"
