Although the defenders at the Border Pass felt immense pressure.
They had no choice but to stand their ground.
On one of the walls at the Border Pass.
An old man in a hemp robe, with four scars on his face and a cultivation base at the Chaos Dao Venerable Realm.
He was none other than Fourth Master Ba.
Jun Wuhui had once saved his life in passing, and he regarded him as his benefactor.
Now, Fourth Master Ba looked stern and shouted loudly.
"Everyone, we have no way out. Aside from victory, there is only Death."
Although Fourth Master Ba's cultivation Realm was not at its Peak.
His seniority at the Border Pass was quite high, and he held significant influence.
As Fourth Master Ba's words spread, mighty shouts erupted across the Border Pass, filled with the resolve to fight to the Death.
Countless Cultivators at the Border Pass roared, holding their positions, preparing to face the greatest war the Nine Heavens Immortal Domain had ever seen.
The vast Border Wasteland was boundless.
A dense army of creatures from the Foreign Domain, carrying an immense and surging aura, swept toward the Border Pass like a black ocean.
The Immortal Kings of the Foreign Domain had not yet appeared, but this endless army alone brought a terrifying pressure.
The great war began directly, leaving no room for any reprieve.
There was nothing left to say between the two Realms; only by completely crippling or annihilating one side could the war between the two Realms possibly end.
Brilliant lights of Spells, terrifying Divine Abilities and Formations, shouts, and the sounds of slaughter.
Finally spread into boundless waves that shook both Realms!
In every major Immortal Domain, one could feel the massive ripples coming from the Border Pass.
All factions that cared about the Immortal Domain dispatched troops to provide reinforcements.
Otherwise, the Cultivators at the Border Pass alone would never be able to hold back the Foreign Domain army.
At this moment, the Border Pass was a scene of slaughter.
The vast Border Pass was instantly dyed red and soaked in blood.
Countless corpses piled up.
"It's no good, we can't hold them off!"
A great knight at the Border Pass roared.
At that moment, a vast aura emerged from the depths of the Border Pass.
It was a Quasi-Emperor level figure guarding the Border Pass taking action, a great hand of Law covering the firmament.
However, from the side of the Foreign Domain army, a cold and disdainful snort rang out.
"Is the Nine Heavens Immortal Domain really this weak? Send out the Emperor-level figures and see if they can suppress the kings of our Realm!"
Powerful figures from the Foreign Domain attacked simultaneously, their might shaking the Border Pass.
The Foreign Domain was incomparably strong, and it had more Emperor-level existences than the Nine Heavens Immortal Domain.
This was also where the Foreign Domain's advantage lay.
Not to mention that although the various clans of the Foreign Domain had their own disputes on normal days.
When it came to the critical moments of the war between the two Realms, they were united.
In contrast, even now, not all factions in the Nine Heavens Immortal Domain had taken action.
The Cang Clan, the Underworld, and others remained completely motionless.
With one side rising and the other falling, the Foreign Domain naturally had absolute confidence in conquering the Nine Heavens Immortal Domain.
At this moment, brilliant Imperial Dao radiance rose from the depths of the Border Pass.
Finally, an Emperor guarding the Border Pass took action, their might shaking heaven and earth.
The experts from both sides immediately clashed.
However, it was clearly just a probe, or rather, an appetizer.
Never mind those disaster-level Immortals of the Foreign Domain.
Even those well-known Immortal Kings, such as Devil King Pu, An Lan, and others, had not yet taken action.
Under these circumstances, the Border Pass fell into an absolute disadvantage.
Some experts from the Foreign Domain were even on the verge of crossing the walls of the Border Pass.
And just at this moment, the reinforcements from the Nine Heavens Immortal Domain finally arrived.
In the distance, countless warships, flying boats, flying ancient beasts, and more arrived, thick and dense, blotting out the sky.
Great armies from various Immortal Domains gathered and descended.
And the most conspicuous one was naturally the Jun Family's force.
Including the Jun Imperial Court and the forces of the Ancient Immortal Court.
On a war ark of the Jun Family.
Jun Xiaoyao stood with his hands behind his back, looking at the endless, blood-stained battlefield.
His gaze was incomparably calm, cold, and deep.
Jun Xiaoyao had experienced many storms.
Not long ago, he had just experienced the mighty battle against the Black Calamity of the Boundary Sea.
So, at this moment, such a scene could naturally not stir even the slightest ripple in his heart.
"It's Lord Divine Son!"
Fourth Master Ba and the others, seeing that long-awaited figure, could not help but show expressions of excitement.
Although Jun Wuhui had already left the Nine Heavens Immortal Domain.
But as Jun Wuhui's son, Jun Xiaoyao had successfully achieved the Dao and transcended the eternal emperor ranking, shocking the entire Nine Heavens Immortal Domain.
Now, his status in the hearts of all living beings in the Immortal Domain was no less than that of Jun Wuhui.
"Jun Xiaoyao!"
On the other side, an expert from the Foreign Domain saw Jun Xiaoyao appear.
Their eyes were filled with coldness and killing intent.
It could be said that the early start of this war between the two Realms was largely due to Jun Xiaoyao.
At the chaotic tide of the Border Wasteland, he had single-handedly trapped and killed six Immortal Kings and wiped out an entire generation of the Foreign Domain's elite.
Causing a generational gap in the future experts of the Foreign Domain.
It could be said that Jun Xiaoyao was now absolutely the person the Foreign Domain hated the most.
Feeling the murderous gazes cast by the experts of the Foreign Domain.
Jun Xiaoyao turned a blind eye, his expression as calm as water.
"Primordial Imperial Clan, it is time for you to play your part."
Jun Xiaoyao's gaze turned in another direction.
Naturally, it was the allied army of the Primordial Imperial Clan.
Since they had sworn the Heavenly Dao Oath, they naturally had to comply.
So now, they could only take the lead, act as the vanguard, and hold the front line.
And when they saw the Primordial Imperial Clan army charging over.
On the Foreign Domain side, an expert could not help but shout.
"Primordial Imperial Clan, are you truly determined to stand on the side of the Nine Heavens Immortal Domain?"
"When the Border Pass is broken and our Realm sweeps through the Nine Heavens Immortal Domain, we will absolutely not leave you any way to survive!"
Facing the shouts and questioning from the Foreign Domain.
No creature from the Primordial Imperial Clan responded.
They couldn't possibly say that their entire Primordial Imperial Clan had been tricked by Jun Xiaoyao alone, right?
That would be too embarrassing.
The Primordial Imperial Clan allied army charged into the Foreign Domain army.
For a time, the battle was tragic and intense.
On this side, Wu Hu and the others asked Jun Xiaoyao: "My Lord, should we take action directly?"
"No rush. Since the Primordial Imperial Clan is fighting so desperately for the Immortal Domain, we must naturally fulfill their sincere hearts."
Jun Xiaoyao did not let the Jun Imperial Court take action directly.
On the side, the ancestors of the Jun Family looked at each other and sighed deeply.
This move of Jun Xiaoyao's was truly ruthless.
The reason he didn't take action was to let the Foreign Domain consume the power of the Primordial Imperial Clan!
And to prevent the Primordial Imperial Clan from being restless again in the future!
A simple move that dealt with the Foreign Domain while also weakening the power of the Primordial Imperial Clan.
So they wouldn't harbor resentment over this matter in the future and stir up any big trouble.
As long as the power of the Primordial Imperial Clan was weakened, they naturally wouldn't be able to cause any trouble.
Seeing that the Jun Family and the Jun Imperial Court took no action.
The Supreme Immortal Court and other factions also made no moves.
In the forces of the Immortal Court, an Emperor-level figure sighed.
"Jun Xiaoyao is truly ruthless. He wants to grind down the power of the Primordial Imperial Clan so they won't be able to stir up any waves in the future."
Even the Supreme Immortal Court had to admit.
Jun Xiaoyao's methods were truly terrifying.
Every step was calculated, every move was planned.
Step by step, he led the Primordial Imperial Clan into a trap, then completely ground down their power.
It wasn't that Jun Xiaoyao was too cold-blooded or too ruthless.
It was just that the Primordial Imperial Clan was too untrustworthy and had too many past offenses.
If not controlled, they might stir up some trouble in the Nine Heavens Immortal Domain again in the future.
The Primordial Imperial Clan was not stupid either. Seeing that the Jun Family and other forces made no move, their hearts immediately sank, and they understood much.
But they could not do anything about it.
Because they had already sworn the Heavenly Dao Oath and could not go back on their word.
Apart from cursing Jun Xiaoyao's black heart in their hearts, there was no other way.
At this moment, the Immortal King level figures of the Foreign Domain finally took action!
