The Eyebrow Sword Style was derived from the Jiang family swordsman's Million Sword Great Art. Later generations, unable to control millions of swords, thus created the Eyebrow Sword Style.

This Eyebrow Sword Style was passable in the hands of its founder, the Old Man with Long Brows. But it grew weaker and weaker afterward, with fewer and fewer practitioners, until now, only the Old Man with White Brows practices this Eyebrow Sword Style, and he is the sole guardian of the Eyebrow Sword Hall; those who pass this challenge are considered to have cleared the Eyebrow Sword Hall.

Among the Five Great Sword Halls, the Eyebrow Sword Hall ranks fifth. However, do not assume the fifth-ranked Eyebrow Sword Hall is easily overcome.

Lu Yuan channeled his magical power to stimulate the growth of his eyebrows. In an instant, his eyebrows, which normally grew from their natural position, cascaded down to his shoulders, appearing utterly demonic.

Having reached the World Realm, life itself trends toward perfection, granting complete mastery over one's own genes; thus, stimulating eyebrow growth was no difficult feat. After Lu Yuan familiarized himself with inducing eyebrow growth, Gu Qiushui, the Flying Sword Master, and Yan Fei, the other three, also completed this step.

The Old Man with White Brows looked at the four: "Since you four are ready, let us begin. First, Lu Yuan." Almost instantaneously, he exerted his power, and countless white eyebrows detached from his own brows, shooting toward Lu Yuan.

His white eyebrows were like innumerable flying swords, momentarily giving the impression of several thousand swords piercing the void. The power of each of these eyebrow-swords was not particularly strong; if one used a true flying sword or sword energy, they could be shattered with a single strike.

The Eyebrow Sword Hall was, by nature, a declining hall; its past supreme techniques had long since vanished into the depths of history. Yet, in this battle, neither flying swords nor sword energy could be used; only eyebrows were permitted.

Lu Yuan also began to command his eyebrows. It was not difficult to command one or two eyebrows to act as swords, but instantly commanding hundreds was arduous.

Lu Yuan discovered this required continuously segmenting his divine sense, thinning it into fine threads to maintain control, equivalent to simultaneously controlling several hundred flying swords—a truly formidable task. Lu Yuan had never truly experienced this kind of combat!

He had always relied on one sword to break ten thousand arts, facing every situation with a single blade; he had never encountered such a style of fighting. For a moment, the eyebrow-swords before Lu Yuan wavered precariously.

At this juncture, the Old Man with White Brows’ Eyebrow Sword Style arrived. His technique would not waver; his swordsmanship was exquisite.

In no time, he had forced Lu Yuan’s countless eyebrow-swords into instability. Within moments, despite Lu Yuan dodging and weaving left and right, he was struck nine times.

Indeed, he was struck nine times with the very first move. The disparity in eyebrow-swordsmanship between the two sides was vast.

The Old Man with White Brows’ assault was not yet finished; several hundred white eyebrow-swords spun ceaselessly around Lu Yuan. Lu Yuan commanded his own black eyebrow-swords to clash with the Old Man’s white ones, but no matter what, he could not contend with the superior white eyebrow-swords, truly unable to adapt to this method of dividing his spirit to control hundreds of flying swords simultaneously.

In the second wave of attacks, Lu Yuan was struck eight more times, bringing the total to seventeen; this meant that with just thirteen more hits, Lu Yuan would have to concede. This was truly an intensely arduous environment.

And then, within his mind, something seemed to faintly blossom. No!

It was not in his mind, but within the space of the Sword Dao. The Small Sword Dao Tree.

It was blooming! That was right!

The Small Sword Dao Tree possessed three inherent iron laws; only one had previously manifested, leaving two great iron laws unrevealed. One of those unmanifested laws was the Law of Adaptation.

Indeed, the Small Sword Dao Tree had recently lacked the necessary nourishment to grow as furiously as before, but the tree possessed its own life and did not rely solely on sustenance for growth. When Zhou Qingxuan spoke of the Law of Adaptation, Lu Yuan had a faint understanding, realizing then that the Law of Adaptation was divided into two: adaptation to the heavens and adaptation to warfare.

The seed of the Law of Adaptation had been sown then, and this seed was combining and reacting with the Small Sword Dao Tree, though due to the fierce battle, Lu Yuan had no time to pay heed. Now, Lu Yuan was under the sustained assault of the Old Man with White Brows.

In the blink of an eye, he was struck seventeen times, on the verge of defeat. What to do?

Only thirteen strikes left. What should he do now?

Right, he still had one final move: the Myriad Manifestations Sword Dao. His Myriad Manifestations Sword Dao could replicate any technique; if it was a sword move, he only needed to see it once to copy it, while other moves required several viewings.

He had been enjoying the Ancient Sword Dao battles so much lately that he nearly forgot his own Myriad Manifestations Sword Dao—a ferocious technique that could once directly copy even the Three Extremes Return to Unity Style of the Son of the Sword. Lu Yuan instantly activated the Myriad Manifestations Sword Dao.

The Old Man with White Brows' white hairs, transformed into flying swords, were, at their core, a form of sword technique. Lu Yuan began simulating it instantly.

The Old Man’s assault arrived again, striking Lu Yuan four times this time. Lu Yuan had now been struck twenty-one times, just nine shy of defeat, but instead of being alarmed, Lu Yuan was delighted.

As expected, his Myriad Manifestations Sword Dao could indeed replicate the Old Man with White Brows' white eyebrow-swords. The next wave of white eyebrow-swords approached.

Lu Yuan’s eyebrows grew wildly, instantly transforming into countless black eyebrow-swords that shot out. The execution of this maneuver was no less skillful than the Old Man’s.

Both sides deployed over two hundred eyebrow-swords, and instantly, over four hundred black and white eyebrow-swords collided in the void. The result of their clash was that all these flying swords tumbled to the ground.

In truth, this multi-control method, managing hundreds of filaments simultaneously, could never be executed with perfect finesse, especially given the delicacy of the eyebrows; thus, a full collision leading to their breakage was perfectly normal. The Old Man with White Brows let out an "Yi." He had expected victory, but Lu Yuan had counterattacked.

Using the same multi-control method, he summoned over four hundred white eyebrow-swords. Lu Yuan, utilizing the Myriad Manifestations Sword Dao, absorbed his summoning method in that instant, raising over four hundred black eyebrow-swords.

Eight hundred black and white eyebrow-swords clashed in the void, ultimately shattering entirely. The fight ended in a draw again.

The Old Man with White Brows paused in surprise. He summoned a thousand white eyebrow-swords; Lu Yuan summoned a thousand black eyebrow-swords.

The two sets of flying swords collided and struck one another in the void, eventually all breaking apart. The Old Man with White Brows grew determined.

He refused to believe it. He was the legitimate heir of the Eyebrow Sword Style; how could Lu Yuan, using the same style, surpass him?

The Old Man with White Brows unleashed his ultimate move: fifteen hundred white eyebrow-swords, his maximum controllable limit. He didn't believe Lu Yuan could control fifteen hundred eyebrow-swords.

To his astonishment, Lu Yuan's eyebrows grew, and fifteen hundred black eyebrow-swords shot out to meet the attack. Instantly, three thousand eyebrow-swords clashed in the air, black and white streaks flying chaotically.

When the three thousand black and white eyebrows finally fell to the ground, the Old Man with White Brows was truly shocked: "You... how could you know the Eyebrow Sword Style, and your mastery is equal to mine?" He was genuinely perplexed.

Lu Yuan merely shrugged, not explaining his use of the Myriad Manifestations Sword Dao: "I can be stronger." With a shift in his technique, two thousand black eyebrow-swords pierced forward. Lu Yuan had grasped the very essence of the Eyebrow Sword Style, which was a method for cleaving the spirit, simultaneously splintering the controlling soul into thousands of pieces.

Lu Yuan’s soul was already incredibly powerful, roughly equivalent to the peak of the tenth level of the World Realm. Coupled with his grasp of the technique’s core essence, he could naturally manifest two thousand black eyebrow-swords.

Seeing this, the Old Man with White Brows was even more stunned. He had practiced the flying eyebrow-sword technique for so long, with a limit of fifteen hundred, yet Lu Yuan had directly expanded the limit to two thousand—how was this possible?

He was the most legitimate successor of the Eyebrow Sword Style; how could he lose to an outsider? The Old Man with White Brows’ mind was unsettled.

This move exceeded his limit, and the sword speed was extreme. Before he could react, the Old Man was struck by even more black eyebrow-swords, hit thirty times, losing the engagement.

"I lose. You have successfully passed the Eyebrow Sword Hall." The Old Man with White Brows sighed with loss: "Did you also learn the Eyebrow Sword Style?

Did you inherit some other lineage of it?" He was truly curious. Lu Yuan shrugged: "I won't be explaining that." The onlookers from the Evil Sword Civilization were all taken aback when they saw Lu Yuan defeat the Old Man with White Brows.

The Old Man with White Brows was not considered a powerhouse within the Evil Sword Civilization. The Eyebrow Sword Hall was the weakest of the Five Great Sword Halls, but it still possessed peculiar skills; many people from the Evil Sword Civilization would struggle to clear it.

Now, Lu Yuan had won. Lu Yuan’s swordsmanship, they thought privately, possessed some level of skill.

However, the vast majority of the Evil Sword Civilization believed Lu Yuan must have practiced some aspect of the Eyebrow Sword Style before, otherwise, he could never wield it as fluently, even more skillfully, than the true successor, the Old Man with White Brows. This clearance of the Eyebrow Sword Hall was attributed to Lu Yuan’s good fortune in miraculously obtaining some inheritance of the style, but the next challenge would not be so easy; this was merely the simplest of the Five Great Sword Halls.

As for Lu Yuan himself, he was immensely exhilarated and excited. Lu Yuan was, at his core, a fervent lover of the sword, always craving novel sword techniques.

It had been a long time since he had encountered anything fresh; the sword styles of the Hidden Sword Sect of the Revealed Sword Gate had become dull, lacking excitement. But upon entering the Evil Sword Civilization, he immediately encountered a thrilling technique: turning eyebrows into swords—truly fascinating.
