Immortal Sword's Birth, Attacking the Underworld

Leaving the battlefield, Zhang Huan sat alone atop Kunlun, the Nether Treasure in his palm.

"How could you be so powerful? Impossible, no one like this should exist in this world again.

This power, have you become an immortal?!"

The divine being, utterly defenseless, was terrified, thinking Zhang Huan had ascended to immortality, no longer the Emperor or Sovereign it knew.

"No, this is... You're forging a path never before seen, excavating the Origin Source of immortal power."

To it, the thirty Emperors and Sovereigns of all ages had never been in its eyes. Besides Emperor Venerate and the Undying Heavenly Emperor from back then, who else could possibly injure it?

But today, it had a change of heart. The person before him possessed monstrous combat power, even touching upon the Immortal Dao. Though not yet an immortal, he could wield the power of the Immortal Dao, which was astonishing.

A faint Divine Sense emanated from the divine being. Though unwilling to surrender, it had already fallen into Zhang Huan's hands.

Zhang Huan forcefully inscribed endless runes onto the Nether Treasure, leaving a mark deep within its immortal Origin Source.

This would make him its half-master, and it would no longer have to fear it suddenly turning on him.

His gaze fell upon the Immortal Pond, and Zhang Huan murmured to himself.

"Chaos gives birth to all things, its creation is infinite, it can be considered thousands of years' worth of Immortal Materials."

The great medicine refined from a damaged Chaos Body was also a rare treasure in the world. Zhang Huan didn't keep it; he tossed the medicine into the Immortal Pond, where it was immediately absorbed.

The Immortal Sword was still short of its full potential and needed primordial essence. It had been nurtured for thirty thousand years in the Ninety-Nine Dragon Mountain. Its Dao and Dharma were now complete, only needing one final push to break free from its embryonic shell.

Seated on Kunlun, Zhang Huan studied the foundations of the Nether Treasure, quietly awaiting the Immortal Sword's perfect emergence.

Compared to his tranquility, the universe was once again in an uproar after a lapse of ten thousand years.

A figure who had shattered the Imperial Dao in their later years, suppressing an immortal artifact – this was a monumental event, destined to become an enduring topic of discussion, a legend in later historical texts.

The Divine Son, pulling strings from behind the scenes, caused the deeds and experiences of the contemporary Great Emperors to be sung anew, with sages from all races rushing to spread the news.

Zhang Huan had long since detached himself from worldly affairs, ignoring the storm brewing in the universe.

The major Forbidden Zones had fallen silent since he killed the Chaos Monster; Zhang Huan's combat prowess left even the Supreme Beings speechless.

The Underworld was the first to flee, vanishing into the void, fearing retribution.

Ten years later, myriad strands of immortal energy descended upon the mortal realm. Upon its appearance, it startled all Emperor Weapons across the boundless void.

Immortal Light surged upwards, scattering immeasurable divine radiance. Brilliant rules flickered in all directions, visible to all beings in the entire universe. It erupted from Kunlun and lingered for a long time.

Immortal flowers rained from the heavens, golden lotuses sprang from the earth, and vast auspicious phenomena spread like an endless tide, as if heaven and earth were praying for this Immortal Sword.

Zhang Huan grasped the Immortal Sword in his hand. The divine being cooperated, and he instantly felt a connection, capable of unleashing immeasurable power.

"Master."

A tender, childish voice connected with Zhang Huan's consciousness. The divine being was overjoyed, finally able to truly be by its master's side.

This was a true Immortal Weapon, and it belonged to him alone.

By relying on the immortal land left behind by the Ancient Heavenly Court, it had saved hundreds of thousands of years of effort to nurture this Immortal Sword.

Zhang Huan burst into laughter. He felt this was the happiest moment of his life, the joy of harvest bringing a smile to his lips.

The immortal scenery of Kunlun gradually faded, and the Ninety-Nine Dragon Mountain ceased its exhalations. The spiritual energy of heaven and earth plummeted, and the place was no longer as blessed and beautiful as before.

Completing an Immortal Weapon had exhausted Kunlun's foundation. Even though it was a place of ascension, it now had thin spiritual energy.

Zhang Huan took out the Dragon Treasure that had reformed in the Dragon Mountain and, drawing upon the grand forces of heaven and earth from the myriad Dragon Veins, used Origin Arts to nourish the spirit. In the future, Kunlun would once again become an immortal land.

Perhaps it would even become closer to immortality. The Dragon Mountain had been destroyed by the Ruthless Emperor in the past; after his repairs, the immortal essence it exhaled would eventually undergo a qualitative change.

The Emperor Formation encompassing Kunlun was not removed. It layered over the Ancient Heavenly Court's Emperor Formation within, capable of concealing all movements in this area.

"The Immortal Sword has emerged. I'll kill a few Supreme Beings to hone its peerless edge."

Zhang Huan's fighting spirit surged. He threatened the Nether Treasure, demanding the Underworld's whereabouts, intending to storm their domain and exact his vengeance.

According to its confession, three more Supreme Beings were supposed to have intervened, with the Chaos Monster as the main force, while they provided support.

But upon witnessing Zhang Huan's strength, they had all retreated back into slumber, none daring to harbor any further ambitions against him.

The so-called turmoil was resolved invisibly, with only the Chaos Monster, who had acted first, perishing.

With the Nether Treasure as a guide, coupled with Zhang Huan's deductions, the Underworld's deepest hiding places were rendered useless.

The fair white sword body exuded Immortal Light, displaying its divine might. Zhang Huan once again broke through the gates of the Underworld, stepping into that Wasteland and unleashing his slaughter.

"Kid, you're going too far. Do you really want to fight a Forbidden Zone to the death?"

Deep within the Wasteland, a Supreme Being awoke and roared, reprimanding Zhang Huan for being too relentless, unwilling to let things go even when he had the upper hand.

Taking one more step forward would mean declaring war on the Underworld, at which point several Supreme Beings would emerge, and even a contemporary Great Emperor could not retreat unscathed.

Zhang Huan's eyes saw through everything, reaching directly to the Supreme Being's hiding place.

Zhang Huan saw a humanoid monster with red hair, like a vengeful spirit, covered in fur.

"What are you, to dare lecture me?!"

Zhang Huan sneered and slashed down with his sword. The entire Wasteland cracked open, forming a bottomless chasm that pointed directly into its depths.

"Boom!"

The sound of an explosion echoed through the Underworld, blasting open a surge of energy as the red-haired ghost emerged and confronted Zhang Huan.

Another supreme being's aura erupted. Two monsters, their hair and fur covering their bodies, appeared.

Origin God, Origin Ghost!

They attacked simultaneously, their Origin Arts reaching the pinnacle of mastery. They utilized the terrain, forming a natural grand formation with the dense death energy that had accumulated in the Wasteland over countless years, the death energy reaching the heavens.

Dao and Dharma clashed and scoured, rumbling sounds spreading throughout the Underworld, forming an unparalleled killing tribulation with the grand formation.

"It's the two of you among the three, isn't it?"

Zhang Huan sneered. These two monsters were of the same kind as that Chaos Monster, and their relationship was already extraordinary. Now, they were so eager to jump out, likely out of fear, wanting to drag the entire Underworld to bolster its courage.

He showed no mercy, holding a Heaven-Piercing Nether Treasure in one hand, forming a barrier to resist the Underworld's death energy. Sword lights rained down, striking the two ghosts so hard they couldn't catch their breath.

In this Underworld, he had no fear of accidentally harming any living beings, so he unleashed his full power in the battle.

The two ghosts retreated together, their auras diminishing by half with each strike of the sword light. Within a few breaths, they could barely maintain their Imperial Dao domain and could no longer contend with Zhang Huan.

"We surrender! Spare us!"

The Origin God roared, his voice hoarse. He had a premonition that if this continued, he would truly lose his life.

The Dao of this contemporary Great Emperor was too profound and terrifyingly evil, capable of even cutting away lifespan, completely suppressing him. He no longer had any intention of continuing the fight.

No wonder the Chaos Monster died so quickly. If it were him, he would likely suffer the same fate!

"You surrender just because you say so? Wouldn't I have just beaten you for nothing?"

Zhang Huan's face was cold, and he had no intention of stopping.

"I am proficient in Origin Arts and have found many rare treasures that appear once in tens of thousands of years. I am willing to offer them all in exchange for the Great Emperor ceasing hostilities."

A look of pain flashed across the Origin God's face. As he spoke, he reached into the depths of the Underworld, and a massive amount of divine artifacts was drawn out, flying before Zhang Huan. They shimmered with radiance, displaying all sorts of treasures.

The light emitted by the divine artifacts outshone the sun, shining as brightly as stars, a dazzling spectacle of colors.

"Your life seems too cheap. Besides, if I kill you, won't these things still be mine?"

Zhang Huan wasn't interested in these items. Although they were rare and unique, having been collected by the Origin God one by one, he wasn't interested. They weren't even as precious as Supreme Being blood.

"This..."

The Origin God was troubled. As he hesitated, the Origin Ghost spoke again, "We can offer an Immortal Medicine, along with Emperor-grade divine materials, hoping to appease the Great Emperor's wrath."

He was decisive, emptying the entire hoard of the two ghosts in exchange for their lives, which pained the Origin God immensely.

This time, they were truly sacrificing their flesh and blood. Every item offered had a grand origin, the accumulation of the two ghosts over countless years, now being given away for free.

At this moment, several other Supreme Beings stepped forward to support the two ghosts, speaking words of mediation and promising various conditions, begging Zhang Huan to spare them. After all, they were all from the same nest and could not stand by and watch them die.

"They attempted to assassinate me before. Although they failed, they had the thought."

Zhang Huan still had no intention of letting them go. If they had the guts, they should let all the Supreme Beings of the Underworld come out. He wanted to bathe in Imperial blood.

The two ghosts trembled all over, shocked. With the strength Zhang Huan had displayed, he was not exaggerating. If he truly intended to go on a killing spree, the Underworld would be in peril.

Thinking of this, they couldn't help but regret it. If only they hadn't been so impulsive with that old Chaos Monster. Now, they were in a desperate situation, like trapped beasts.

The Prison Suppressing Emperor pondered for a moment and slowly spoke.

"This matter is the Underworld's fault. Not only will we compensate you, but we will also join forces to create a supreme law for your descendants.

All beings in the Underworld, regardless of their cultivation level or seniority, shall jointly honor your lineage.

All your direct disciples will be on par with the various Imperial Dao figures, able to command a hundred ghosts, enjoy the immeasurable fortune of the Underworld, and be titled Nether Imperial Lords."

"With this, are you satisfied?"

The Prison Suppressing Emperor said, attempting to appeal to Zhang Huan's emotions. Most Great Emperors in their later years were concerned with securing benefits and blessings for their descendants, and he assumed Zhang Huan was no different.

After all, he had experienced it himself, bringing many people to the Underworld, and Zhang Huan also had his own forces, the Demonic Court.

They were making a significant sacrifice; no one in history had ever received such an honor. No matter who Zhang Huan's descendants were, they would be on par with Emperors and co-rule the Underworld.

This could ensure the eternal peace of his lineage. As long as the Underworld existed, this lineage would endure forever.

The resources and treatment they would receive were even higher than those enjoyed by the Imperial Sons of Supreme Dao forces.

"Do the decrees you issue hold true for yourselves? What if they are revoked in the future? Do you dare to make a solemn oath and willingly accept the constraints?"

Zhang Huan was somewhat moved. The conditions offered by the Underworld were indeed generous. The Myriad Things Soil, Chaos Divine Materials, and Immortal Medicine—they were giving their all.

"Supreme Beings will establish covenants. We will not interfere with your lineage. If we violate it, the Imperial Dao laws will backfire."

"I am not at ease. I want to participate to ensure you have sufficient power to enforce the covenants, and the Origin God and Origin Ghost must have restrictions inscribed upon them.

They already harbored murderous intent towards me. After this battle, they will inevitably bear grudges. I need to place restrictions on their souls to prevent any unforeseen events."

"Agreed, but they cannot be restrictions like enslavement. They can only affect their actions, at most preventing them from resisting."

Zhang Huan was satisfied. Such restrictions were sufficient. He approached the two ghosts and reached out to grab their souls.

Even though the two ghosts were indignant, they endured it silently without resistance. Their strength was inferior, and they didn't even have the right to decide their own fate, only able to obey the arrangements of the Prison Suppressing Emperor and Zhang Huan.

At least their lives were saved. The two ghosts breathed a sigh of relief in their hearts.

Subsequently, all the Supreme Beings of the Underworld awakened and, with Zhang Huan, condensed an imperial decree using Imperial Dao laws. It emitted golden light, jointly stipulating the contents, and under Zhang Huan's supervision, the enfeoffment was completed.

This was no mere set of rules written on paper; it possessed true Imperial authority and couldn't be trifled with.

Using the Dao as a medium, it connected to the depths of everyone's soul. Zhang Huan had personally participated, leaving behind contingencies and taking the decree directly.

If any Supreme Being broke the contract, Zhang Huan had a way to ensure they would at least be severely injured by the backlash.

He asked the two ghosts who else had been involved in the failed rebellion, and they pointed their accusations at the Divine Ruins.

That person's lifespan was running out. They needed to stir up chaos to replenish their vital essence, or they would die in the Forbidden Zone within a few thousand years.

They were well-behaved, having been beaten into submission and their souls controlled. They immediately revealed everything about that person's background.

"So that's how it is. Their lifespan is running out, no wonder they were so impatient, plotting Demonic Cultivation Methods and scheming for Emperor's Blood."

Zhang Huan nodded, his gaze flickered, signaling to spare them. The two ghosts repeatedly expressed their gratitude and immediately vanished without a trace.

He spared the two ghosts not because he was truly swayed by the Underworld, but because he planned to harvest them sustainably in the future.

He still remembered the red-haired figures he saw when he was cutting Origin in the past. An Immortal Treasure that displayed scenes of Flying Immortals had been stolen by them without anyone noticing.

The two ghosts had profound attainments in Origin Arts and enjoyed seeking treasures hidden in the world; they were the best treasure hunters.

Keeping them to work for Zhang Huan meant future harvests would bring pleasant surprises.

The brand he had placed on them was not easily removed. As long as the restriction remained, those two ghosts could not escape his control.

Zhang Huan put away the Immortal Sword.

The various Supreme Beings, seeing this, peacefully fell into slumber, and the Origin Gods and Origin Ghosts also sealed themselves. Zhang Huan was the only Emperor left awake in the Underworld.

They had promised Zhang Huan many benefits and handed over more than one supreme scripture related to Great Emperors, all hidden deep within the Underworld for Zhang Huan to comprehend himself.

At this moment, he also held a title in the Underworld, co-ruling it with the Ancient Emperors, allowing him to roam the depths of the Wasteland legitimately.

The Supreme Beings' plan was quite shrewd: they wanted to pull Zhang Huan's lineage into the Underworld and turn enemies into friends.

But they would never have dreamed that Zhang Huan's "descendant" was none other than Zhang Huan himself.

Now, enjoying the sweet offerings from the Underworld, and in the future, seizing the Underworld's assets. The cannonball, after its sugar coating was removed, would be returned in full. Such a development would undoubtedly make the Underworld's Supreme Beings spit blood, having suffered a silent, devastating loss.

Ordering the Underworld Lord to lead the way, Zhang Huan moved among the ancient steles, examining them one by one.

He had long wanted to explore the secrets of this place.

The ancient steles contained not only the legacies and insights of many ancient sages but also various secrets from ancient history. Only a place like the Underworld, which had endured through the ages, could preserve these completely.

"Harmony Flower, it appeared in the Primeval Era! It helped an unknown figure become an Emperor!"
