The entire Boundary Sea and all its living beings had never felt such a stifling and oppressive atmosphere.
There were not many living beings left who had experienced the ancient Black Calamity, also known as the Second Black Calamity.
Therefore, most living beings in the Boundary Sea had never truly experienced the World-Annihilating Black Calamity.
Facing it now, they naturally felt anxious and gripped by a heavy sense of oppression.
In such a situation, the panicked masses naturally wanted to find a center, a pillar of support.
"Where is Young Lord Yun Xiao? Where is he?"
"It seems he is still in seclusion to Cultivate at the World Core."
Many people's first thought was not some supreme powerhouse or a Pass Guardian.
It was Jun Xiaoyao!
Indeed, this young junior, without anyone realizing it, had gained significant weight in the hearts of the living beings of the Boundary Sea.
They knew clearly that although Jun Xiaoyao's strength was Heaven-Defying and he was a Prodigy.
His age of Cultivation was limited, after all.
No matter how much of a Prodigy he was, he could not possibly have too great an impact on a Black Calamity war of this scale.
Because his strength was limited.
However, Jun Xiaoyao now seemed to have become a pillar of support in the hearts of the Boundary Sea's living beings.
Jun Xiaoyao's Cultivation level was far inferior to those top-tier supreme existences.
Yet, for some reason, whenever they thought of Jun Xiaoyao's calm and composed Heart-Nature, unperturbed even if Mount Tai were to collapse before him.
All living beings felt an inexplicable sense of stability in their hearts.
From this, one could see what level of prestige Jun Xiaoyao had reached in the Boundary Sea.
It could be said that he was deeply rooted in people's hearts.
It could be said that, setting aside his Cultivation Realm and so on.
Jun Xiaoyao's prestige in the Boundary Sea was now almost on par with the Three Emperors.
Mainly because the things Jun Xiaoyao had done and his achievements were so great that they did not match his age and Cultivation level at all.
Many people subconsciously felt that Jun Xiaoyao was born to create miracles.
As time passed.
Someone discovered that, over in No Mans Land, the Black Calamity Tribes seemed to have started moving again.
There was a vast, dark mass of living beings gathering like a black tide.
"It is the Devourer Clan! Is the Devourer Clan about to make a move?"
Some people became alert.
The destruction caused by the Devourer Clan to the Boundary Sea was terrifying.
They were like a swarm of tireless locusts, endlessly eroding the worlds and Universes of the Boundary Sea.
Everywhere they passed, there was only ruin.
At this, the entire Boundary Sea was thrown into complete turmoil.
Every faction knew that the final decisive battle was likely approaching.
The Black Calamity Tribes seemed to be launching a full-scale assault.
The various factions of the Boundary Sea, the Three Teachings, the Imperial Clans, and other immortal forces, etc.
All rushed to the Three Emperors Barrier to prepare for battle.
Not everyone had the courage to fight to the death.
However...
Where could they run to?
With the World-Annihilating Black Calamity, the entire Boundary Sea would be destroyed, leaving no place to survive.
Did they expect to cross the dam and head to the Nine Heavens Immortal Domain or other worlds?
Not to mention whether they had that ability.
Even if they did, it would only be a temporary escape.
If the Black Calamity was not completely eradicated, it would sooner or later spread to the Nine Heavens Immortal Domain.
Therefore, it was not that these Cultivators and living beings of the Boundary Sea did not fear death.
But rather, they truly had no way out.
The only way was to fight to the bloody end!
The Three Emperors Barrier became unprecedentedly bustling as countless factions arrived.
Factions from the Origin Universe also joined in.
The Xuanyuan Clan, the Yun Sheng Imperial Palace, and other sub-ultimate factions also dispatched their teams, bringing out all their elites.
At this moment, there was no longer any distinction between the Boundary Sea and the Origin Universe.
The Origin Universe was also a part of the Boundary Sea.
Along the long battle line of the Three Emperors Barrier, countless Cultivators and living beings from the Boundary Sea gathered, packed densely together.
It could be said that this was an unprecedented sight.
It was also the most united moment for the Boundary Sea.
Everyone knew that not to fight was to die!
And in this waiting.
Finally, on this day, someone saw.
On the opposite side of the Three Emperors Barrier, over in No Mans Land.
A clamorous sound arose.
Rolling black mist surged over like a tide.
If one looked closely, one could see.
Within that black mist were countless shadowy figures.
They were all Zombie Demons, fallen Cultivators, and strange creatures from No Mans Land that had been tainted by the eerie aura.
These creatures that had fallen into darkness, dense and numerous, charged toward the Three Emperors Barrier.
The entire Three Emperors Barrier had a very long battle line, spanning both ends of No Mans Land.
And those dark creatures surged over like a tide, present in every area.
One could see how terrifying their numbers were.
And what was even more terrifying was yet to come.
Behind these creatures from No Mans Land, a dense army of the Devourer Clan appeared.
These dark creatures, similar to an insectoid race, were even more terrifying in number.
The Devourer Clan was known for its numbers; now that they had swarmed out in full force, one could imagine the scale.
No Mans Land was clearly vast and boundless.
But at this moment, it looked as if it had been forcefully filled up by these creatures!
The horror of their numbers was evident!
"Raise the Formations, quickly!"
A commander of the Boundary-Suppressing Army on the side of the Three Emperors Barrier couldn't help but shout.
Signals were sent out from every pass.
The Three Emperors Barrier was inscribed with the most powerful offensive and defensive Formations, which would only be used in the most critical moments.
Because once activated, the resource consumption was too great.
"Has it finally begun?"
At various passes along the Three Emperors Barrier, towering figures appeared.
They were all Pass Guardians of the Three Emperors Barrier.
"Then let it begin."
These Pass Guardians held the control authority over the supreme Formations of the Nine Great Passes.
And at Yanggu Pass, after the Huangfu Imperial Clan was wiped out, a supreme powerhouse had temporarily taken the position of Pass Guardian.
Immediately, across the Nine Great Passes of the Three Emperors Barrier, terrifying Formation fluctuations appeared.
In the Void Realm, complex and endless Formation patterns were branded, and terrifying fluctuations emerged.
Offensive Formations, defensive Formations, augmentation Formations, suppression Formations.
The divine radiance of various Formations surged between heaven and earth.
Those offensive Formations turned into brilliant torrents, falling upon the incoming creatures of No Mans Land.
In an instant, the world shook, and countless living beings were wiped out in a flash.
However, no living beings retreated.
Whether it was the Zombie Demons, fallen Cultivators, or strange creatures from No Mans Land.
Or the army of the Devourer Clan, none retreated.
They seemed to lack the concept of fear, still charging forward without fear of death.
A great war unfolded, with no room for anything else.
And with the charge of those creatures from No Mans Land and the army of the Devourer Clan.
The battle line was constantly pushed forward, getting closer and closer to the Three Emperors Barrier.
Although for every step forward, the number of living beings lost was uncountable.
The Black Calamity side did not care at all.
Of course, among these living beings, there were also extremely powerful existences that could resist the Formation attacks and get closer and closer to the Three Emperors Barrier.
"Boundary-Suppressing Army, take orders, attack!"
Voices came from every pass.
Some quasi-Emperor level commanders shouted, leading their troops into battle.
The Three Emperors Barrier was the most solid defense line of the Boundary Sea.
If it were breached, the trouble would be immense, and it would be even more difficult to stop them.
Therefore, the most urgent thing now was not to let the Black Calamity Tribes breach the defense line of the Three Emperors Barrier.
The Boundary-Suppressing Army made their move, engaging in slaughter with those dark creatures and Devourer Clan creatures that had broken through the encirclement.
This was not the small skirmish of before, but a true full-scale war!
