Black Blade Yoru let out a mournful cry.
The tremors on the blade stopped instantly.
That proud resistance was crushed by the power of the Body of the Extreme Path.
Just one second.
This unparalleled Black Blade thus completely submitted to the hands of Uchiha Xin.
It was as docile as a piece of ordinary scrap metal.
The Hawk Eyes floating on the sea was deeply shocked by what it saw.
He gasped, a chill running down his spine.
That's Black Blade Yoru!
It took him several years to subdue this sword, nurturing it day and night with his sword intent before he could barely control it.
The man before me simply uttered a cold rebuke and clenched his fist with one hand.
I was instantly captivated by this Supreme Grade Sword!
This overwhelming power has exceeded Hawk Eyes's cognitive limits.
Uchiha Xin weighed the Black Blade Yoru in his hand, then casually hung it on his waist.
He looked down at the Hawk Eyes on the sea.
This man has an extreme dedication to the way of the sword.
Even when facing an invincible opponent, they dare to wield their swords.
He was even willing to hand over his sword, which he considered his life, as an apology.
This pure warrior's spirit earned Uchiha Xin's admiration.
"I'll spare your life for now."
Uchiha Xin spared Hawk Eyes's life.
"Your dedication to the way of the sword is quite admirable."
"I'll make a promise with you."
Uchiha Xin's tone was domineering and left no room for argument.
"If you can withstand three of my moves and survive in the future..."
"Then I will take you under my command and have you work for me."
Hawk Eyes floated on the sea and, upon hearing the agreement, offered no objection.
He willingly accepted this opportunity.
Because he knew very well that the man before him had reached a supreme level that he could not reach.
Being able to follow such a powerful figure is definitely an unparalleled opportunity to glimpse a higher realm.
I accept this agreement!
Hawk Eyes responded loudly.
"One day, I will withstand three of your moves and reclaim Black Blade Yoru!"
Uchiha Xin didn't waste any more words.
He put his hands in his pockets, turned around, and started walking.
The power of the Body of the Extreme Path circulated beneath his feet.
He strode through the air, his figure quickly disappearing into the vast sea.
Hawk Eyes was left alone on the sea, gazing in the direction he had gone, unable to come to his senses for a long time.
Not long after Uchiha Xin left that sea area.
A crisp notification sound suddenly rang in his mind.
"Bite!"
The long-dormant system suddenly popped up a notification panel.
Lines of text appeared in Uchiha Xin's vision.
[Host detected defeating a key plot character: Dracule Mihawk.]
[Skill successfully unlocked: Observation Haki!]
[This skill can be socketed. Socket it now?]
The sudden notification took Uchiha Xin completely by surprise.
He stopped and stood on the sea, carefully examining the system panel.
During the previous interdimensional teleportation, the system core had clearly entered a deep slumber.
There was no intelligent response.
But now, a completely new feature has suddenly been unlocked.
Uchiha Xin's brain worked at lightning speed, and he quickly noticed the pattern.
Although the system does not provide intelligent solutions, its basic mechanisms are still functioning.
From this, he deduced the system's new function.
The system has added a mechanism where defeating an opponent will randomly grant the user their abilities or skills.
Uchiha Xin stood steadily on the undulating sea, his hands in his pockets.
His innate ability Body of the Extreme Path allowed him to walk as if on flat ground, without even getting his shoes wet.
His attention was now completely focused on the system panel in his mind.
Right in the center of your vision, a skill icon emitting a faint golden light is quietly floating.
[ Observation Haki ( Dracule Mihawk's Exclusive Version): The world's top-tier sensory ability in Pirate King.]
Uchiha Xin looked at the skill that had just been unleashed by Hawk Eyes, his eyes revealing a hint of scrutiny and weighing.
" Observation Haki..."
He pondered to himself.
In terms of sheer range and absolute insight, his twelve- Tomoe Eye of God could even see through multi-dimensional space and the essence of the soul.
His own innate perception had long surpassed the basic abilities of this so-called Observation Haki.
This kind of native skill from the pirate world should have been useless to someone of his caliber.
"However, the special effects of this thing —Future Sight and reading minds to hear the Voice of All Things— are quite interesting; it does have some value."
Uchiha Xin stroked his chin.
However, he ultimately decided to embed it into his skill slot, his core purpose not being to covet this meager boost to combat power.
"System, the repulsive force of the laws governing this world is far too strong."
Uchiha Xin frowned slightly as he felt the Power of the Extreme Path within his body being suppressed, as if it were in a deep slumber.
The cross-dimensional teleportation, coupled with the rejection from the Deva Path of another world, rendered his proud Law of the Extreme Path temporarily unusable.
It would take an extremely long time to adapt if one were to forcibly break through this suppression.
However, if one gains control of the local power structure, the situation becomes entirely different.
" Devil Fruit are not only rare, but eating them also incurs a curse from the sea; they're practically counterproductive."
Uchiha Xin scoffed at the Devil Fruit.
"But the Haki is different."
" Haki is the innate potential possessed by everyone in this world; it is a native power born from the physical body and spirit."
"Once I cultivate domineering Haki, it's like giving myself a legitimate identity in this world."
"With this identity as a cover, I can gain the recognition of the laws of the Pirate King World Law more quickly and unseal the dormant Power of the Extreme Path within me sooner!"
Having figured this out, Uchiha Xin no longer hesitated.
"System, immediately infuse Observation Haki!"
[Ding! Command confirmed!]
[Integrating Observation Haki into the host...]
[Inlay successful!]
As the system's cold, mechanical voice faded, Uchiha Xin felt a sudden clarity in his mind.
A peculiar wave of perception emanated from him and instantly spread outwards to all directions of the sea.
Fish swimming hundreds of meters below the surface, the trails of the sea breeze in the distance, and even the movement of water molecules in the air were all clearly reflected in his mind at this moment.
This feeling is different from the absolute insight of the Eye of God; it is a wonderful experience of being completely integrated into nature and listening to the breath of all things.
However, before Uchiha Xin could fully savor this novel feeling, he glanced at the system panel and his face immediately darkened.
"System, what's going on?"
Uchiha Xin pointed to the progress bar behind the Observation Haki skill bar, his tone clearly showing displeasure.
Why is the proficiency level for this skill locked?
On the system panel, the level of Observation Haki was fixed at a specific value.
The following text was clearly marked in large letters: [Unable to upgrade using system proficiency].
