Black Nether Demon Domain.

Numerous forces from the Black Nether Demon Domain had assembled their armies and once again invaded the Azure Nether Dao Domain.

At the same time, beyond the domain, the Crimson Peak Star Domain had opened a passage into the Azure Nether Dao Domain.

The Crimson Peak Star Domain's supreme power, the Crimson Peak Alliance, joined forces with the Black Nether Demon Domain. Using overwhelming force, they shattered the defensive barrier of the Azure Nether Dao Domain and launched a full-scale invasion, determined to carve up the territory.

The various powers of the Azure Nether Dao Domain had no choice but to form another alliance to face the crisis.

War raged across the lands.

Many disciples of Falling Emperor Mountain descended the mountain and headed to the border passes to resist the invasion of the Crimson Peak Alliance and the Black Nether Demon Domain.

On Falling Emperor Mountain.

Su Chen felt utterly helpless. A full century had passed, yet he had not produced a single heir. At his level of cultivation, conceiving offspring was extraordinarily difficult.

However, the more difficult it was to conceive a descendant, the greater their innate talent would be. The child of two saints would enter the world already standing at the pinnacle for countless others.

"Bad news, Mountain Lord! This is terrible!"

Outside the grand hall.

An elder rushed in, panic written all over his face.

Su Chen couldn't help but feel that those words sounded strangely familiar.

Once the Falling Emperor Mountain elder had caught his breath, Su Chen asked, "What happened? Why are you so flustered?"

The elder hurriedly replied, "Mountain Lord, Senior Dragon Saint has fallen into an ambush set by experts from the Crimson Peak Star Domain. He has been suppressed by the Nine Nethers Great Saint of the Crimson Peak Star Domain, who intends to take Senior Dragon Saint as his mount!"

Su Chen's expression turned grave.

Long Qiu had actually been ambushed by the Crimson Peak Alliance. And now someone wanted to subdue him as a mount.

Su Chen left Falling Emperor Mountain. A Great Saint-level expert could cross an entire domain with ease. It would not take him long to reach the battlefield.

Beyond the starry sky, above the boundless sea of stars.

A holy spirit clad from head to toe in silver battle armor sat cross-legged atop a massive seal. Beneath the array's suppression lay a blazing fire domain capable of incinerating everything. Long Qiu was trapped deep within that sea of flames.

"So you are Nangong Chen? The number one genius of the Azure Nether Dao Domain in ten thousand years? Someone with the potential to become a Great Emperor?"

The holy spirit in the silver armor watched the white-robed man intrude upon the scene with great interest and fired off three questions in quick succession.

You might be reading a stolen copy. Visit Royal Road for the authentic version.

Unfortunately, Su Chen offered no reply.

The aura of the sword tore through the sea of stars, sending countless holy spirits into a state of terror.

From the direction of the Azure Nether Dao Domain came waves of excited voices.

"It's that person from Falling Emperor Mountain… He has taken action. After so many years, his strength has grown even more terrifying."

"I didn't expect the Crimson Peak Alliance to provoke this man. They're going to be in serious trouble now."

"A bunch of fools. They're being used as pawns and don't even realize it. Do they really think they can afford to offend the Sword Saint Nangong?"

"..."

Su Chen's personal intervention undoubtedly gave the forces of the Azure Nether Dao Domain a tremendous boost in morale.

The Nine Nethers Great Saint, however, paid no attention to any of this. A light chuckle rang out from within the silver armor. "It seems the natives have great faith in your strength. Unfortunately for them, you've met me. Losing to me is no disgrace. It will be your honor!"

Su Chen gripped the Profound Jade Ancient Sword in his hand.

With tens of thousands of years of experience, Su Chen considered himself well-acquainted with countless prodigies, yet he had never encountered anyone so shameless.

The Nine Nethers Great Saint continued, "I was born in the Crimson Peak Star Domain. From the moment I began cultivating the martial path, my cultivation surpassed all my peers. I became a sage in five hundred years, breaking the Crimson Peak Federation's cultivation record. I have also refined the highest-grade battle armor of the Crimson Peak Alliance and visited countless star domains, facing innumerable prodigies. Unfortunately, none of them were worthy of even a single strike from me!"

Sword qi surged forth. In an instant, countless stars and seas of stars turned to dust.

Behind Su Chen, an ancient giant sword hovered, illuminating the starry sky. Its extreme and razor-sharp destructive killing intent sent countless living beings in the cosmos trembling with fear.

"This is the sign that the Innate Supreme Sword Body is about to reach great completion… Has Nangong Chen really reached this stage?"

The Innate Supreme Sword Body was one of the pinnacle physiques in the sword dao. The word "supreme" said everything. Once this terrifying physique reached great completion, it would grasp the origin power of the sword dao and step into the legendary taboo realm. Even as a Quasi-Emperor, its destructive power would rival that of the supremes who had sealed themselves in forbidden zones.

Although Su Chen had not yet entered that taboo realm, he was still incomparably terrifying. In the current era, no one could compare. Even among the countless prodigies of the golden great era, very few had reached this level.

A conspicuous scar appeared on the Nine Nethers Great Saint's silver battle armor, leaving him in disbelief.

"How is this possible? This is the legendary Silver Dragon Battle Armor. You actually managed to injure me?"

Su Chen replied calmly, "Why not? If you were wearing the legendary Emperor Armor, I might have shown some restraint. But a pirated inferior copy dares to test the edge of the sword in my hand? How ridiculous."

The Innate Supreme Sword Body was the ultimate killing physique. Otherwise, the old Mountain Lord of Falling Emperor Mountain would never have valued Su Chen so highly.

Seeing that the situation had turned against him, the Nine Nethers Great Saint immediately fled toward the Crimson Peak Star Domain.

Su Chen slashed open the seal with a single sword strike and rescued Long Qiu.

Looking at the gravely wounded and dying Long Qiu, Su Chen handed him over to a powerhouse from the Azure Nether Dao Domain. Then, with a cold gaze, he pursued the fleeing Nine Nethers Great Saint alone.

The two of them crossed layer after layer of star domains. All living beings in the places their powerful auras passed trembled in fear.

The moment Su Chen stepped into the Crimson Peak Star Domain, terrifying killing arrays descended from all directions, completely enveloping the entire star domain.

Countless fearsome starships floated behind the Nine Nethers Great Saint within the Crimson Peak Star Domain. From the four cardinal directions, four terrifying Great Saint-level experts emerged out of thin air.

"Nangong Chen… Today is the day of your death. Your corpse will contribute greatly to our Crimson Peak Federation. We will use every means possible to research and create a new Innate Supreme Sword Body!"

A damaged Emperor Array sealed the star domain. Five Great Saints unleashed their full power together, and countless starships capable of threatening sages rose into the sky.

Faced with such a terrifying encirclement, a bronze oil lamp appeared in Su Chen's hand. It burned eerily in the starry sky, emitting an icy chill.

Su Chen smiled. His smile was extremely cold. If he destroyed an entire star domain. His lifespan would once again be extended by several thousand years.

"Now I can finally… let loose!"
