The fusion of these Iron Laws has always been a momentous undertaking.

The Three Extremes Unification—this was the lifelong pinnacle achievement of the Sword Son, directly replicated by Lu Yuan. To then incorporate the Yin-Yang Disc was possible because Yin-Yang was the second Iron Law he had mastered, making him intimately familiar with it. Furthermore, the Dao Character Clone played its part, enabling the inclusion of the Yin-Yang Disc, resulting in the Four Extremes Unification form.

This was essentially Lu Yuan’s absolute limit.

To then integrate the incomplete Great Karma Disc and the incomplete Order Iron Law made the difficulty exponentially greater.

The more Iron Laws one attempted to unify, the harder the task became.

Lu Yuan tested for a long time, yet consistently failed to bring the Six Great Iron Laws into unification.

Even pushing his Dao Character Clone to its extreme could not merge the Six Great Iron Laws.

Was he destined to fail?

Although the majority of Lu Yuan’s focus remained within his Sword Space, he noticed that the injuries sustained in the external battle were accumulating rapidly. He was currently relying entirely on the Supreme Rigid-Tender Body to hold out, but even that could not last much longer—perhaps the time equivalent of one stick of incense. If he could not devise the method for the Six Great Iron Laws Unification within that period, he would lose this fight.

Lose!

He absolutely refused to lose.

Some battles one could afford to lose.

But some battles must be won; winning them was imperative.

This battle, for instance, had to be won, because standing behind it was Mount Hua; to protect Mount Hua, he had to prevail here.

A surge of conviction erupted within Lu Yuan’s heart, yet in this moment, even conviction seemed to offer little aid.

What to do?

Lu Yuan fell back into deep contemplation. The Dao Character Clone was useless, the Small Sword Dao Tree yielded nothing, and the Gate of the Sword Dao also offered no solution. These were the Ten Great Iron Laws of the cosmos, not just the ten laws of the Sword Dao. The Laws of Dharma, Martial Arts, Buddhism, and the Desolate Path—they all drew from these ten fundamental principles. How could he proceed?

In an absentminded motion, Lu Yuan summoned forth the Sword of Seven Emotions, Jian Jiu, the Sword of Seven Emotions! This sword differed entirely from the others. Sword Eight possessed no physical form, only manifesting when needed. But Jian Jiu, the Sword of Seven Emotions, always had substance—a sharp longsword shimmering with seven hues of light, poised to strip away the seven core emotions: joy, anger, sorrow, fear, love, hate, and desire.

Lu Yuan casually drew the Sword of Seven Emotions across the Great Karma Disc. He seemed to notice that the Great Karma Disc felt significantly clearer, its nexus points drawing much closer to the convergence points of the other four extremes.

What was this?

Lu Yuan froze, utterly failing to comprehend the phenomenon.

How could passing the Sword of Seven Emotions across it simplify the fusion of the Iron Laws?

Lu Yuan couldn't help but test it again. Upon doing so, he confirmed it worked. He passed the Sword of Seven Emotions over the River of Order, and observed that the River of Order also moved significantly closer to converging with the four extremes. What was happening? Lu Yuan sank back into thought, instantly grasping one possible explanation.

The Ten Great Iron Laws of the cosmos, in their natural state, existed in harmony and should not inherently resist one another, primarily orbiting the Dao Character under its influence.

However, when these ten laws passed into the hands of individuals, they became tainted by each person's unique emotions, causing them to resist each other and become difficult to command.

His Sword of Seven Emotions absorbed the seven sentiments and six desires, effectively cleansing the major Iron Laws of these emotional residues, allowing them to revert to their original, unadulterated states. Once returned to their fundamental nature, they found the Dao Character Clone already present—and not just any clone, but a nascent Dao Character Clone—allowing them to naturally begin coalescing around the Dao Character Clone as their core entity.

Lu Yuan gazed ahead at the emerging spectacle: the Wheel of Reincarnation, the Yin-Yang Disc, and the Great Karma Disc—three vast, unyielding wheels slowly manifesting in the sky, forming a perfect triangle. Simultaneously, the River of Order, the River of Time, and the River of Space converged in that same instant.

It was a scene of ineffable grandeur.

An unbelievably magnificent vista.

It felt as if an epic was being recited, the mysteries of heaven and earth vibrating between the three wheels and the three rivers.

Lu Yuan himself was utterly, profoundly shocked!

When he achieved the Three Extremes Unification Stance, he hadn't felt this level of astonishment.

But now, with the Six Extremes Unification Stance—even in its incomplete form—witnessing what appeared in the sky left him completely stunned. Lu Yuan now realized that his study of the Iron Laws was, in essence, mastering the secrets behind all movements in the cosmos. If he could master all ten, he would grasp the complete essence of every technique and variation in existence.

Heaven, the universe, and all things were contained within.

This was the mystery of the cosmos, ineffable by mere words.

Lu Yuan suddenly felt a sharp pain in his chest and snapped back to awareness. A sword had pierced him, inflicting another serious wound.

With his eyes shut inside the Sword Hall, he was still enveloped in absolute darkness. This was a battle waged in shadow, and within that darkness, the Evil Extreme Celestial Venerable slowly retreated. This followed the rule of dark combat: once a significant blow was landed upon the opponent, the attacker would withdraw briefly to reposition before launching the next assault from an unforeseen angle.

Darkness brought silence, movement was untraceable, and prediction was impossible; it was profoundly mysterious.

These were the rules of fighting within the Blindfolded Sword Hall practice. Moreover, such methods were necessary in many unique environments throughout the world. Training in the Blindfolded Sword Hall was supremely practical, unlike the Eyebrow Sword Hall, which possessed not an ounce of practical application. Lu Yuan, the Venerable thought, you will be defeated precisely through this practicality.

The next strike would be Lu Yuan’s undoing.

The Evil Extreme Celestial Venerable schemed inwardly, lamenting, Pity, young man from the outer domain; you are about to perish here. This is the consequence of challenging the majesty of the Evil Sword Civilization.

After waiting a brief interval, the Evil Extreme Celestial Venerable attacked from an inscrutable, erratic angle. At that precise moment, Lu Yuan’s sword met the Evil Extreme Celestial Venerable’s blade. The two swords clashed in the void with a resounding clang, echoing sharply in the darkness.

Oh, it was parried this time? The Evil Extreme Celestial Venerable immediately retreated, planning his next advance. Combat in darkness required patience, accurate judgment, and exquisite swordsmanship. So what if it was blocked this time? Lu Yuan was surely doomed to lose.

At that instant, the Evil Extreme Celestial Venerable heard Lu Yuan speak: “One sword.”

One sword? the Evil Extreme Celestial Venerable pondered internally. What does that mean?

“I will deliver one strike next. If you manage to evade it, I’ll concede you are skilled,” Lu Yuan stated calmly.

“One strike? Can you even reach me?” the Evil Extreme Celestial Venerable retorted. His voice was not fixed in one location but dispersed across countless points. This was also a common tactic in dark combat, but the Evil Extreme Celestial Venerable’s execution was far more masterful; even one employing anti-tracking sound methods would struggle to locate his true position.

“Of course, I can reach you.” In a flash, Lu Yuan unleashed the sword strike he had been preparing for so long.

Almost instantaneously, the Wheel of Reincarnation, the Yin-Yang Disc, and the Great Karma Disc materialized in the void, arranged in a triangle. Simultaneously, the River of Order, the River of Time, and the River of Space also appeared, the Six Great Iron Laws intersecting and converging in the emptiness.

Of course, Lu Yuan could not see this phenomenon, nor could the Evil Extreme Celestial Venerable.

But even without sight, it could be felt.

The Evil Extreme Celestial Venerable could sense that within this single sword strike, time seemed to halt its rotation, and space felt utterly solidified. The void appeared to contain endless cycles of reincarnation, as if any flaw he presented would be observed by a pair of hawk-like eyes fixed upon him in the darkness. Moreover, every past event in his life seemed to resurface in his mind; every old injury throbbed faintly, and he felt the very order governing all things.

The Evil Extreme Celestial Venerable even sensed, vaguely, that he was hearing the voice of the Great Dao, as if this strike were saturated with its ultimate truth.

What in the heavens is this technique!

The Evil Extreme Celestial Venerable was nearly driven mad. He could not see the strike at all, but his instincts screamed of its terrifying power, and he clearly felt it aimed directly at him. The Evil Sword Supreme activated his Evil Extreme Void Immortal Sword, attempting to block the incoming attack, only to discover immediately that his immortal blade was being crushed by the single strike Lu Yuan had delivered.

Too powerful!

This strike was overwhelmingly strong!

The Evil Extreme Celestial Venerable tried desperately to flee, but found that even as he retreated, this sword followed him, moving slowly yet relentlessly fast. The strike had not concluded; it continued its pursuit. In that moment, the Evil Extreme Celestial Venerable felt his very soul scattered, throwing everything he possessed into defending against this attack.

Lu Yuan’s sword-light chased after the Evil Extreme Celestial Venerable.

Lu Yuan knew that this strike was not yet finished.

The essence of this sword-art had not yet been fully expended; he could feel it, knowing this single strike would become the most powerful he had ever wielded in his life.

It was a blade of light, simultaneously dazzling and dignified, developing and extending with the rhythm of the Great Dao, relentlessly pursuing the Evil Extreme Celestial Venerable.

Above or below, there seemed to be no sanctuary left for the Evil Extreme Celestial Venerable to escape to.

As previously mentioned, within the Blindfolded Sword Hall, besides the Evil Extreme Celestial Venerable, there were several hundred others—all masters of the Sword Dao, all accustomed to fighting in the dark. Though none faced the direct brilliance of Lu Yuan’s strike, and none could behold its stunning dignity, they all felt an instinctive terror regarding this sword.

What kind of strike is this! To elicit fear from those seasoned in countless battles—they now desperately wished to clearly see what this sword looked like, but alas, they could not.

They truly could not see, for the entire space remained shrouded in darkness, turning their anticipation into frustration.

They were habitually comfortable with, even fond of, fighting in the dark, but now, because they couldn't witness the light of this sword, the very darkness became a source of regret.

This sword-strike continued its relentless journey.
