Gu Jinlai became one with his sword, like a supreme divine weapon descended from the sky, thundering down towards the Horned Dragon Demon King with unbelievable speed.
The Horned Dragon clearly sensed a life-and-death crisis. However, having just unleashed its Demon Flame and hurled three sharp horns at Lan Yuhua, it was in the throes of exhaustion. There was no time to dodge the sword light coming from the sky, and it could only roar, pushing the Demon Flame inside it to the extreme.
The Demon Flame seemed to contain a power that burned the spirit, annihilating rationality, enough to cause any Martial King who had not yet condensed the Martial Arts Will to run amok, even to the point of losing control.
By nature, Gu Jinlai was already a Heavenly Monarch.
Martial Arts Will, the power equivalent to the fusion of a martial artist’s essence, Qi, and spirit, although primarily of spiritual will, mixed with the power of Qi and blood, could still slightly impact Gu Jinlai.
But as for the demon...
Even a Demon King with a Perfect Demon Body, bursting with boiling Demon Flame, still couldn’t harm Gu Jinlai in the slightest.
The dazzling thunder light mixed with the brilliant sword aura directly shattered the boiling Demon Flame and fiercely slashed into the body of the Demon King.
The ferocious power, like a meteor falling from the sky, instantly shattered the twenty-meter-tall body of the Demon King.
Flesh flew everywhere.
The scattered power mixed with blood mist formed a visible shockwave, spreading indiscriminately in all directions.
The Demon King with a Perfect Demon Body let out a painful scream as its huge body hit the ground hard, driven by the inertia formed by Gu Jinlai in the Man and Sword as One.
Stray hurricanes cut sword marks into the ground within a hundred meters, even severing large trees that were ten to several tens of meters tall.
Wood chips flew everywhere, tearing a nearly inhabitable zone out of an area with a hundred-meter radius.
This terrifying destructive power was even comparable to a small-yield nuclear bomb.
The massive form of the Horned Dragon tumbled to the ground, stirring up dust and air waves.
Despite suffering such a heavy blow, the strong life force allowed it to struggle, seemingly trying to get back on its feet.
However, although the Divine Power of the Thunder Sword somewhat lacked in killing power, its accompanying paralysis effect was not something that could dissipate in a short amount of time.
Seizing the opportunity, the figure of Gu Jinlai, who was bombarding downwards, suddenly swelled, transforming into a ten-meter-tall giant.
Subsequently, he slashed out with his Quasi-Dao Artifact Level War Sword...
Electricity propelled!
The sword strike, accelerated to two strokes, three strokes, and further escalated to ten strokes, twenty strokes, thirty strokes...
The Sword Gang roared.
Sword Qi crisscrossed.
The Demon King, just struggling to stand, was caught in a storm of Sword Qi, instantly torn to shreds under the violent barrage of sword lights.
In a scream of agony, the huge body of the Horned Dragon was split into dozens of sections, literally scattering flesh and blood.
The entire process barely saw any substantial counterattack from the Demon King; struck by the Thunder Sword and paralyzed, it was torn to pieces with irresistible force.
Seconds later, when Lan Yuhua, the accompanying Primordial Spirit Monarch, and other Martial Kings recovered their senses, the Demon King was left without even a complete corpse.
Lan Yuhua gasped in shock.
"Is... Is this the power that we Martial Kings can possess?"
Yuan Cuo, possessing the power of a Peak Martial King, felt a shudder in his heart, his face filled with uncontrollable astonishment.
And the Primordial Spirit Monarch holding the Quasi-Dao Artifact flying sword felt his heart tremble even more.
If every Martial King were as powerful as Gu Jinlai, what standing would they, the most top-ranked Monarchs of the Primordial Spirit Realm, have to be equals with Martial Kings?
At that moment, a series of deafening roars came from the distance.
These were other Demon Marshals and even Demon Kings, who had reacted and were roaring to gather demons to encircle and kill Gu Jinlai and the others.
Seeing this, Gu Jinlai wasted no more time.
Sixty thousand demons...
Even though his combat strength surpassed that of Peak Heavenly Beings, if he were trapped, he could still be worn down to death by these demons with their terrifying numbers.
He immediately decapitated the Demon King, leaped up, and, in a flash, landed on the back of the Marching Bird.
Then, he shouted to Lan Yuhua and the others, who had yet to recover their senses from his lightning-fast beheading move: "What are you dazing for? Go!"
Startled by his shout, Lan Yuhua and the others jerked awake.
Seeing the demons rushing toward them like a tidal wave, he hastily said, "Go, go, go! Let’s go!"
"Hit and run, truly thrilling!"
"Fly up, fly up, the number of Demon Marshals among these devils is already few in number. As long as we reach an altitude of a kilometer, we can be at ease," said one.
The group exclaimed and controlled the Marching Birds to soar straight into the clouds.
During this, Lan Yuhua harnessed the power of Heaven and Earth to create fierce winds, enabling the Marching Birds to ride the wind and increase their speed even further.
Below, Devils continued to roar incessantly, and the group could even discern the anger in those roars.
But as they gradually distanced themselves, their tense emotions also gradually eased.
By the time they completely flew out of the mountain range, Lan Yuhua and several Martial Kings looked at each other and couldn’t help but burst into laughter.
"Hahaha, I never thought that slaying a Demon King would be so easy! It’s like... taking the enemy general’s head in the midst of an army!"
"Decapitating a Demon King is most difficult for two reasons, first, finding where the Demon King is, and second, being able to slay the Demon King amid a circle of devils. Yet these two challenges seem trivial in the presence of Ancient Martial King."
"Indeed, those devils never expected us to come so swiftly that they had yet to gather other devils or even the Demon King by their side before we beheaded him. If other Demon Kings or even Demon Marshals had surrounded him, our difficulty in decapitating him would have increased significantly!"
"Today, Ancient Martial King has truly taught us a lesson, inflaming in us the principle of the importance of divine speed in warfare!"
Several Martial Kings, including Lan Yuhua, spoke out, expressing the joy brought about by their thrilling operation.
Even Yuan Cuo, who had previously been somewhat hostile to Gu Jinlai, now looked at him with a hint of admiration.
As a Martial King himself, he had now reached the pinnacle of what it meant to be a Martial King.
What he needed to do next was to allow his Martial Arts Will to guide his Martial Arts Divine Power to transform his body, even reconstructing it, and thereby evolving to Martial Saint.
As for further enhancement...
At this point, essentially no further enhancement was possible.
Even if he possessed a body of Dao Artifacts, without the ability to harness the power of Heaven and Earth, he couldn’t unleash the true power of the Dao Artifacts.
