The small purple sword skimmed through the air, spinning rapidly, appearing so ethereal as if it were not real.
However, when Chu Yukou and everyone from the Moon Wheel Sect in the distance saw this sword, their souls trembled, and their faces immediately changed.
What kind of treasure was this?
"A Soul Treasure?" Su Yi exclaimed in surprise.
"It seems I can't hide it from your discerning eyes, fellow Daoist. The Purple Imperial Sword is indeed a Soul Cultivation secret treasure, nurtured within my sea of consciousness for the past fifty years."
A hint of a smile appeared at the corner of Autumn Hengkong's mouth. "This sword possesses extraordinary spiritual connection and complements my sword heart. Its power is boundless. When I obtained the sword's recognition at the Golden Rainbow Demon Mountain all those years ago, I couldn't have imagined such good fortune for myself."
His words were filled with emotion.
Evidently, being able to gain the loyalty of the Purple Imperial Sword was a matter of great pride and joy for him.
"To have a Soul Sword recognize you as its master is enough to prove that your Sword Dao is exceptional," Su Yi nodded.
A Soul Treasure referred to a treasure used by harnessing the power of the soul. Due to the extremely demanding materials required for its refinement, such treasures were incredibly rare and scarce in the world.
The secret to refining such treasures was generally held by the Soul Cultivation lineage, and only Spirit Path cultivators who had condensed a "Divine Soul Ling Platform" possessed the ability to refine them.
Even among the top Soul Cultivation sects in the vast wilderness, only core disciples had the opportunity to obtain a "Soul Treasure" from their sect elders.
For Autumn Hengkong to possess such a Soul Cultivation secret sword was truly comparable to obtaining a tremendous stroke of luck.
"Be careful, fellow Daoist!"
From a distance, Autumn Hengkong called out, and the Purple Imperial Sword flashed suddenly, abruptly disappearing.
It vanished without a trace!
Only in the "divine sense" of cultivators like Chu Yukou, who were in the Yuan Dao realm, could they barely perceive the three-inch-long Purple Imperial Sword, which appeared like an illusory light, crossing a hundred feet of empty space and slashing towards Su Yi.
It was unbelievably fast, comparable to teleportation.
Such a sword, if used against a martial cultivator in the fourth realm, would undoubtedly result in an instant kill without any awareness.
Even against a fellow Yuan Dao cultivator, the power of a Soul Cultivation secret treasure was sufficient to deliver a deadly blow when least expected.
However, Su Yi was different from other warriors. Although he was at the Precelestial Martial Ancestor realm, he had already condensed his divine sense when he was in the Grandmaster realm. His soul power was unparalleled, and he possessed mastery of the enigmatic Soul Secret Arts.
In such a situation, he was by no means helpless.
In an instant, a gleam of light flashed in his eyes, and his soul power condensed into a green-colored secret sword, bursting forth from the center of his brow.
The Divine Annihilation Sword!
That green-colored secret sword was the "Annihilation Sword" formed by his soul.
Clang!
An ear-piercing explosion reverberated, tearing through eardrums.
The three-inch-long Purple Imperial Sword was blocked and struck forcefully, causing the sword body to tremble violently before being repelled.
This deadly strike was thus completely neutralized.
It may seem easy, but if it were any other Yuan Dao cultivator, even if they could withstand it, their divine soul would likely suffer damage!
In the distance, Autumn Hengkong, who controlled the Purple Imperial Sword, flickered and emitted a muffled groan, his face turning pale.
When manipulating a Soul Cultivation secret treasure with divine sense, one's own divine sense and soul would be affected when subjected to an impact.
"Fellow Daoist truly possesses remarkable methods. Not only do you master the enigmatic Soul Secret Arts, but the strength of your divine soul is enough to make me, a Yuan Dao cultivator, feel ashamed," Autumn Hengkong sighed.
He had indeed never expected that Su Yi not only possessed divine sense but also wielded unimaginable Soul Secret Arts. This made his Purple Imperial Sword lose its lethal deterrent power against Su Yi.
Chu Yukou's expression in the distance fluctuated between gloom and anger.
This was already the eighth move executed by Su Yi.
So far, Autumn Hengkong had been at a disadvantage throughout, which made him both astonished and apprehensive.
The atmosphere within the Moon Wheel Sect became heavy.
Everyone could see that the Purple Imperial Sword was the trump card of Elder Autumn Hengkong, but it seemed to have little effect in front of Su Yi.
This gave rise to a sense of unease in everyone's hearts.
Meanwhile, at a distance of three hundred zhang, Tea Jin's tightly strung heartstrings finally relaxed a little. It was then that she realized she had been gripping her hands tightly, her fingernails piercing her palm, causing a faint tingling sensation.
"The Soul Sword is useless against me. Do you have any other means, fellow Daoist?" Su Yi asked.
"Naturally," Autumn Hengkong took a deep breath and flexed his fingers.
Clang! Clang! Clang!
Under his finger force, the Scarlet Plumage Sword, Green Grain Sword, and Purple Imperial Sword all trembled violently, resonating together, creating a surge of sword chants.
The auras of the three swords, in a peculiar manner, merged together.
Autumn Hengkong's own aura was pushed to the utmost, with a hint of sweat appearing on his brow, clearly indicating that he had concentrated all his power on wielding these three swords.
"For fifty years, I honed the Green Grain Sword with my cultivation, tempered the Scarlet Plumage Sword with my qi and blood, and nurtured the Purple Imperial Sword with the power of my divine soul. Now, I have united these three swords with my lifelong Dao, yet their combined might has never been revealed to the world."
With a solemn and calm voice, Autumn Hengkong looked towards Su Yi from afar, revealing a slight smile. "Today, I invite you to witness it, fellow Daoist!"
Then, his hands pressed into the void, and his voice thundered like a spring thunder:
"Go!"
Whoosh!
The Green Grain Sword took the lead, swiftly darting out, its three-foot-long blade resembling a streak of refined metal, accompanied by a vast expanse of green and golden radiance.
Soon after, the Scarlet Plumage Sword and the Purple Imperial Sword followed suit, whistling through the air one after another.
The three swords connected from end to end, forming a straight line. As their auras merged and resonated, their power surged with each passing moment.
The elemental qi of the surrounding heaven and earth surged forth, making the terrifying might of this united trio of spiritual swords even more formidable.
"This..."
The onlookers were all shocked and stunned.
"He truly deserves to be the Grand Elder of my Moon Wheel Sect, the unrivaled giant of the Great Wei's swordsmanship for a hundred years!" Chu Yukou was amazed.
Autumn Hengkong's sword encompassed the culmination of his fifty years of arduous cultivation. His cultivation, divine soul, and vitality merged into the three swords, becoming one entity. It was enough to make ghosts and gods tremble, shocking the heavens and earth!
"What a terrifying sword! I wonder how the young master will deal with it..." Tea Jin's nervous heart felt as if it was about to leap out of her chest.
"Excellent!" Faced with this sword, Su Yi exclaimed, his eyes brimming with a surge of battle intent.
He finally held nothing back.
With a flick of his sleeve, the Xuanwu Sword resounded with a resolute and soaring cry, releasing a three-foot sword aura.
As soon as this sword was unleashed, it instantly became the finishing touch, exuding an indescribable charm. It seemed invincible, capable of tearing the heavens and earth apart.
It was like an unstoppable force that could sever the shackles of the heavens and earth and break through illusion and reality.
This was Su Yi incorporating his profound mastery of swordsmanship and his spiritual essence into a single sword. With just one sword, he fused his cultivation, divine soul, and physical strength, infusing the resonance of the five aggregates, allowing this three-foot sword aura to radiate an unprecedented power.
When this sword was unleashed, the twilight sky scattered, and the void became dim and lightless, with only a trace of purity becoming the sole glimmer.
How swift was this sword, descending upon the mortal realm!
Boom!
In the world, the Green Grain, Scarlet Plumage, and Purple Imperial Swords stood unparalleled, like white rainbows piercing through the sun, comets attacking the moon, carrying an overwhelming momentum.
And the sword unleashed by Su Yi appeared in the sky.
A three-foot sword aura against the three spiritual swords!
Clang!
The heavens and earth quivered and boomed like thunder.
First, the Green Grain Sword couldn't withstand it and was forced back.
Immediately after, the Scarlet Plumage Sword was also shattered, staggering and retreating.
Just as it seemed that Su Yi's three-foot sword aura was about to clash with the Purple Imperial Sword, an incredible scene occurred.
The defeated Green Grain Sword and Scarlet Plumage Sword spun around and came behind the Purple Imperial Sword, connecting end to end, and then fiercely merged together.
Clang!
The three spiritual swords merged once again, and their power became even more terrifying than before.
In the distance, Autumn Hengkong revealed a smile.
This was the sword he had honed during his fifty years of seclusion, utilizing the power of his cultivation, divine soul, and physical body. He concealed all variables and killing intent within it, far from being as simple as a head-on collision.
But in the next moment, Autumn Hengkong's smile froze abruptly.
On Su Yi's three-foot sword aura, five sword mountains suddenly surged, resembling ancient towering divine mountains, carrying a majestic might that suppressed everything.
Undoubtedly, his strongest sword held hidden variables, but Su Yi's three-foot sword aura also contained the essence of the great Dao!
Boom!
In the eyes of the crowd, the three-foot sword aura and the three spiritual swords collided violently, unleashing a terrifying destructive torrent that seemed to shatter the heavens and earth.
In that void, only a blaze of light remained, and the vision of the onlookers turned into a vast expanse of whiteness. Their ears went deaf, and all senses were subjected to the impact.
Only Chu Yukou could clearly see that a vast and terrifying destructive force spread in all directions from the point of contact between the two, like a hurricane ravaging the sky.
When those destructive auras spread to the ground, the courtyard in front of the entrance of Mount Lomo, spanning hundreds of feet, was crushed and ruthlessly torn apart, leaving behind countless visible cracks on the earth.
Three hundred zhang away, Tea Jin immediately dodged to a safe distance.
The destructive aura was too terrifying, possessing the power to crush mountains with just a wisp of it!
"Who will win and who will lose?"
In the eyes of most people, the sword unleashed by Autumn Hengkong after fifty years of arduous training would be the doom of even a Yuanfu Realm cultivator. Su Yi, no matter how strong, should not be able to withstand it. Even if he didn't perish, he would at least suffer severe injuries.
Even Chu Yukou had such speculation in his mind.
But when the dust settled and everything returned to silence, an astonishing scene unfolded, leaving everyone dumbfounded.
Above the void, the chaotic energy gradually dissipated, the radiance scattered, and a three-foot sword aura pressed against Autumn Hengkong's throat, three inches away.
The sword aura was clear and ethereal, causing goosebumps to rise on Autumn Hengkong's skin at the point where it touched his throat.
His face turned pale, his eyebrows filled with astonishment. His body stiffened in place, not daring to make the slightest movement. Deep inside, an unstoppable wave of shock and fear surged.
Su Yi's sword had broken through his strongest attack. In that instant when the sword's edge met his throat, Autumn Hengkong even thought that he was undoubtedly dead.
Because in that moment, he had no chance to resist at all!
"Why... didn't you strike to kill, fellow Daoist?"
After a moment, Autumn Hengkong's eyes slightly lifted as he looked into the distance, his expression complex and remnants of fear still lingering in his eyebrows.
In the distance, Su Yi held the sword's hilt behind his back, his green robe fluttering in the void, standing proudly like an immortal.
