Demon Slaying, Gaining 60 Years of Cultivation From the Start

"How is it?"

At this moment, Gu Chen turned his gaze toward the Ancestor of Shadows, his eyes gradually turning cold and indifferent.

The battle between the two forces was fierce, though the Wan Gu Royal Court had suffered some losses as well. Compared to the Yin World, their condition was incomparably better.

In fact, it could be said that Gu Chen's Wan Gu Royal Court was utterly suppressing the Yin World's army.

To the point where even the fifteen Demon Monarchs could not lift their heads in the fight—several of them had already been resurrected multiple times within mere moments.

The Ancestor of Shadows remained silent, his expression cold. Although the Yin World's army could endlessly regenerate, heal from various wounds, and even resurrect, this process was not without limits.

As previously mentioned, whether it was a spectral demon, an evil fiend, a celestial demon, or beings of the Demon King or Demon Monarch level, each resurrection consumed the Yin World's source energy.

Of course, weaker entities caused negligible consumption of the source energy and could be replenished within a fraction of a moment.

However, the continual resurrection of beings at the Demon Monarch level greatly drained the Yin World's core essence.

Short battles were still manageable, but if it turned into a protracted war, this was the last scenario the Ancestor of Shadows wanted to see.

"Useless trash!" he said coldly.

As these words landed, the bodies of the fifteen Demon Monarchs trembled on the battlefield. They, too, were baffled as to why the Wan Gu Royal Court's forces were so overwhelmingly strong. Such power could easily be described as surpassing all levels of supremacy in history!

"So this is why you merged the source of Yang into the celestial order?" The Ancestor of Shadows glared at Gu Chen.

"Indeed. At this rate, without even needing me to intervene, how much longer can you hold out?" Gu Chen's gaze remained icy cold as he looked at the Ancestor of Shadows.

The reason was simple: the Ancestor of Shadows himself embodied the Yin World's source. Each successive downfall of a Demon Monarch drained him significantly.

He could either abandon the Demon Monarchs altogether or continue this stalemate with Gu Chen. Either way, the scale was undoubtedly tipped in favor of the Wan Gu Royal Court.

Yet, at this moment, the Ancestor of Shadows suddenly laughed. He said, "Do you think I truly have no means beyond watching this unfold?"

Gu Chen remained silent, calmly observing his opponent.

"Enough. It seems a mere junior like you has indeed underestimated me. With the endless accumulation of my years, I have manifested my true form today—to show you my real power!" As the Ancestor of Shadows spoke, his face grew ever colder.

Boom!

In the next moment, this ancient being finally made his move. A black iron halberd tore through the void, erupting like billions of dark suns detonating simultaneously. The magnitude of its energy was overwhelming!

Even those engaged in battle from afar felt their hearts tighten, as though they were on the brink of annihilation.

Gu Chen, seeing this, knotted his sword-like brows. With a wave of his sleeve, he isolated himself and the Ancestor of Shadows from the outside world, neutralizing the devastation emanating from the attack.

At that moment, Bi Yu and the others heaved a sigh of relief and refocused on their skirmishes against the Demon Monarchs.

Soon, the Ancestor of Shadows launched his assault. This time, compared to the battle three thousand years ago between the two, his true form far outstripped the strength he had wielded back then.

Clang!

A deafening collision reverberated—its tremors synchronized with the grand fabric of the cosmos. Were it not for Gu Chen sealing off their battlefield, merely the sound of their strikes could have obliterated the Wan Gu Royal Court and the entire Yin World army.

Such was the disparity between them!

At this moment, Gu Chen wielded the Disorder Calming Sword and blocked the Ancestor of Shadows' attack.

The Ancestor of Shadows frowned slightly—he hadn't expected that Gu Chen, having forsaken the Yang source, would grow even stronger compared to three thousand years ago. He now almost stood as an equal to the Ancestor's peak state form.

Boom! Boom! Boom!

Following this, the Ancestor unleashed a series of devastating strikes. The pitch-black iron halberd in his grasp transformed into something akin to a world-ending demonic dragon, its immense power accompanied by supreme, dark chains attacking Gu Chen relentlessly, intending to disintegrate him entirely.

Gu Chen, with the Disorder Calming Sword in hand, unleashed billions of sword beams in an instant—each ray more brilliant than the starry seas. Within each beam lay the profound mysteries of the highest order of swordsmanship, knowledge beyond the reach of even the most supreme cultivators.

Countless sparks erupted between them, and each spark held the capability to annihilate an entire world!

This was a battle of transcendence—an apocalyptic confrontation poised to destroy the cosmos, a duel that could be dubbed the ultimate battle since the dawn of all worlds!

Their fight would decide the future trajectory of the unified cosmos, once the forces of Yin and Yang merged.

If Gu Chen triumphed, the heavens would retain hope. Should the Ancestor of Shadows prevail, the universe would be plunged into an everlasting purgatory.

Clang, clang, clang, clang!

The two exchanged countless blows—Disorder Calming Sword versus the iron halberd—old adversaries in a sense.

Gu Chen casually wielded various supreme swordsman techniques, each of them divine and unparalleled. Even the Ancestor of Shadows found himself dazzled by their sheer magnificence.

"Hmph!"

Seeing the stalemate persist, the Ancestor let out a snort and shattered the barrier Gu Chen had erected, intending to annihilate everything in this cosmos.

Gu Chen, upon noticing this, would naturally not let it succeed. With a wave of his sleeve, the Battle Shifts Stars, worlds turned to seas and seas turned to worlds!

They vanished from sight!

"The Lord of the Royal Court has gone to the beyond to slay the enemy leader. We cannot lag behind—kill these wretched fiends!"

Bi Yu roared, unleashing his supreme cultivation, facing two Demon Monarchs simultaneously and shattering them repeatedly.

"Kill!"

The Wan Gu Royal Court's army was now brimming with momentum. Their killing intent filled the universe as they clashed relentlessly with the celestial demons of the Yin World.
