Facing a Half-Step Overlord who was not inferior to himself, Aoyuan was still quite polite. No one was willing to provoke a Half-Step Overlord, not even a super-powerful Chaos Ancient Universe like the Alien Ancient Universe.
While not afraid, standing on opposite sides would still be troublesome.
Ye Chen revealed a faint smile. "And what if I insist on participating?"
Hearing this, Aoyuan's expression darkened considerably, his voice turning cold. "If Fellow Daoist insists on this course and chooses to become an enemy of my Ancient Universe, I cannot stop you. However, I ask you to consider the consequences of opposing my Ancient Universe before you act. Throughout all ages, my Ancient Universe has roamed invincible, having shattered countless Chaos Ancient Universes. Even the glorious and prosperous Pangu Universe of the Mythical Era was crippled by my Ancient Universe, its Heavenly Emperor trapped, its Giants displaced, its Heavenly Dao incomplete. I wonder if Fellow Daoist is willing to bear such a price?"
His words were now an open threat!
But the Alien Ancient Universe had the confidence to threaten. Throughout the entire Chaos Sea, only the Primordial Immortal Realm, and perhaps the Origin Sacred Clan that once unified the Chaos Sea in the past, could be mentioned in the same breath as the Alien Ancient Universe.
"Threatening me?" Ye Chen chuckled, utterly unfazed. "The tricks of the alien race truly haven't changed much throughout the ages."
Aoyuan's expression sank. It seemed the other party was not swayed by threats and was determined to intervene.
He took a deep breath. Facing a Half-Step Overlord, while not afraid, how could he not be wary? Just as he was about to say something more, his expression suddenly changed.
Boom—
The Chaos Sea erupted. Ye Chen suddenly moved, but not to attack Aoyuan. Instead, he pierced through the void, arriving before the retreating Alien Giants. Without a word, he unleashed the might of a Half-Step Overlord, descending from the sky to launch a fierce assault on that Alien Primordial Giant.
"How dare you!"
Aoyuan roared, charging over at the same instant.
However, he was ultimately a moment too late, forced to watch helplessly as Ye Chen struck at the Alien Primordial Giant.
"No—"
The Alien Primordial Giant panicked and roared, mustering all his power to defend. With a deafening boom, the vast region of the Chaos Sea around that boundary collapsed and sank.
The Primordial Giant's weapon, bearing the brunt of the attack, was struck until its radiance dimmed and cracks appeared. It was then sent flying back, crashing heavily into its wielder.
Blood sprayed. The Alien Primordial Giant's figure was sent hurtling through the air, his blood sprinkling the Chaos Sea. His body cracked, his flesh and Dao bones shattered, suffering an extremely terrifying, grievous wound. He was covered in blood!
With just a single strike, a Primordial Giant was severely wounded!
The residual force, undiminished, transformed into terrifying shockwaves that radiated outwards, knocking aside the other Alien Giants. Each coughed up blood, looking utterly disheveled.
"A pity. He's a clever one, knowing to block with his Dao weapon first. Otherwise, he might have been blasted apart." Ye Chen glanced at the blood-soaked Alien Primordial Giant, shaking his head slightly with regret.
Although a Half-Step Overlord was far stronger than a Primordial Giant, they were not completely invincible. Just as an Ancient Giant found it difficult to kill a Quasi-Giant in one blow despite the vast gap in power, the opportunity was fleeting. By now, Aoyuan had already arrived, and Ye Chen had lost his chance. He sighed softly.
Aoyuan was both shocked and furious but did not press the attack.
It was not appropriate. Besides Ye Chen, there was also Donghuang. Once Donghuang emerged, facing the combined assault of two Half-Step Overlords, even he would be in grave danger, risking suppression or even death at any moment. He could not afford to be careless.
Filled with anger and helplessness, Aoyuan flicked his sleeve, sweeping up the surviving Alien Giants and the immeasurable Alien army, then turned and left.
Watching Aoyuan's retreating figure, Ye Chen felt a hint of admiration. Truly worthy of an old monster who had lived for endless eons, he was indeed wise and understood the balance of advantages and disadvantages.
However, being alone, it wasn't wise to give chase.
If he truly provoked other Alien Half-Step Overlords, his identity might very well be exposed. For now, it wasn't the besttiming.
With a light laugh, he turned and left, entering through the Taiyu Pass.
The Immortal World soldiers who had witnessed Ye Chen's battle with the Alien Giants naturally did not dare to stop him. Instead, they looked at him with reverence as if he were a deity. Without a doubt, this was a peerless existence.
Although the Taiyu Pass had been shattered, Ye Chen had the Immortal Great Celestial Venerate stay behind to temporarily guard it.
With the Immortal Great Celestial Venerate's capabilities, unless a Half-Step Overlord attacked, even an ordinary Primordial Giant was no match for him. He alone was enough to hold the fort.
Arriving at the Donghuang Sacred City, he saw that due to Donghuang's return, all beings within the sacred city were exhilarated.
The three Immortal Kings were also immensely excited. Donghuang, who had been gone for multiple epochs, had finally returned, reversing the crisis and proving his invincible might.
"Fellow Daoist Ye," Donghuang said.
"Senior!" The three Immortal Kings—Taiyu, Haozun, and Jiuyou—though covered in blood, still bowed in respect.
By now, they naturally understood that Donghuang's return was entirely due to this mysterious senior, hence their deep respect.
"Are you all alright?" Ye Chen inquired.
The three Immortal Kings shook their heads. "Some injuries, but nothing serious."
Ye Chen nodded, then swept his gaze over the Donghuang Domain, frowning slightly. "The Donghuang Domain has been sealed and shielded."
"There is a traitor within the Immortal World who used an Immortal Venerable-level Great Formation to seal the entire Donghuang Domain." Donghuang's calm tone carried an endless chill.
"Who is it?" Ye Chen wasn't particularly surprised, because even during the Great Cataclysm of the Pangu Universe's Mythical Era, a supreme existence from the Primordial Immortal Realm had intervened.
Clearly, some within the Primordial Immortal Realm had always maintained connections with the Alien Ancient Universe.
"We'll know soon." Donghuang gazed in a certain direction, speaking lightly. "After all, this Sovereign's Dao weapon is not something just anyone can obtain."
Boom—
The Immortal Venerable-level Great Formation enveloping the Donghuang Domain suddenly trembled violently, materializing from invisibility and unleashing Immortal Venerable-level might that shook the entire Primordial Immortal Realm.
At this moment, other regions of the Primordial Immortal Realm could finally sense the Immortal Venerable-level Great Formation shrouding the Donghuang Domain. Supreme Immortals were startled, especially the Immortal Kings, who gazed into the distance towards the Donghuang Domain with expressions of shock and surprise.
When had the Donghuang Domain been enveloped by an Immortal Venerable-level Great Formation? None of the various powers were aware.
"Hmm?" The blurry figure was startled. "Why would the Immortal Venerable-level Great Formation activate inexplicably? It should have remained hidden."
But soon, his expression changed, because the Immortal Venerable-level Great Formation was crumbling, its formation patterns rapidly disappearing, revealing the entirety of the Donghuang Domain.
The world saw it and their expressions changed one after another.
The borderland Taiyu Pass had collapsed, with heavy casualties. There were terrifying remnants of Immortal King-level battles that had sunk vast stretches of the Immortal World's land spanning tens of millions of miles, annihilated countless star rivers. Immortal King blood still lingered between heaven and earth, and the will of Ancient Giants remained.
Without a doubt, a world-shaking battle had occurred in the Donghuang Domain—an Immortal King-level one, and not just in one location.
They had been completely unaware of all this, and their faces paled.
However, when their gazes looked towards the distant Donghuang Sacred City, they saw the three Immortal Kings appearing together. Even more shocking was a familiar, invincible figure standing at the center of the three Immortal Kings, radiating boundless immortal light, suppressing the Immortal Venerable-level Great Formation!
"Donghuang!"
