They were worried that the alien race's subsequent assassination attempts would become even more frenzied.
Just learning that the Battle Saint King could defeat a First Heaven Sovereign had already prompted them to dispatch such a terrifying lineup. If they knew he could single-handedly battle five Ancient Monarchs, including three Second Heaven Sovereigns, even a Supreme One would likely take action at all costs.
In less than a year, the Battle Saint King had grown so much. Even the Strongest Emperors would probably be shocked upon learning this, and might also be willing to act without restraint.
Because alien spies had infiltrated silently, even into the Flame Emperor City—the most important place in the Flame Emperor Domain, right under the emperor's nose—and nearly succeeded in assassinating the Battle Saint King, the security of Flame Emperor City was tightened countless times over.
Any powerhouse arriving from outside, no matter who, had to undergo rigorous inspection.
The Emperor personally took charge, his divine sense constantly enveloping Flame Emperor City, not relaxing for a single moment.
A day later, the Flame Emperor returned from deploying the Domain War battlefield and instantly learned of Ye Chen's attack, which had occurred right within Flame Emperor City.
This Giant, who had recently become a Strongest Emperor, was enraged. Infinite phenomena soared into the heavens, illuminating half of the Origin Ancient Path.
The next moment, the Flame Emperor directly charged into one of the alien race's Supreme One Domains and attacked in fury.
On this day, the seemingly calm Origin Ancient Path experienced a massive tremor.
The Flame Emperor invaded the alien race's Supreme One Domain, descended upon the imperial cities of several Supreme One Domains, and without a word, forcefully attacked the resident alien Supreme Ones.
Boom— Boom—
Boundless blood radiance boiled, sweeping across the entire Origin Ancient Path, drawing the attention of the entire world!
Two alien Ancient Great Emperors were utterly shattered, their emperor souls torn apart, their emperor dao origins fractured, suffering terrible damage at their very core.
The Supreme Ones of the Origin Ancient Path were greatly shaken, watching the Flame Emperor's forceful attack in astonishment, unclear why the Flame Emperor, who had risen so powerfully in the past two years, had suddenly taken action.
Even knowing the Flame Emperor was absolutely hostile to the alien race, he had never acted so recklessly before, tearing through the surface and directly invading the alien race's Supreme One Domains.
"Flame Emperor!"
On the alien race's side, the Strongest Emperors who had endured for countless ages were also alerted and appeared.
Such Giants usually spent their time comprehending the greater Dao, attempting to advance into the elusive realm of eternity, but at this moment, they were thoroughly roused.
Beside them, the manifestations of multiple alien Supreme Ones appeared, standing tall on the Origin Ancient Path, confronting the Flame Emperor, watched by the entire world.
The world was puzzled as to why such a major event had suddenly occurred.
The Flame Emperor showed no fear, his aura as a Strongest Emperor suppressing all heavens and realms.
Behind him, the eight Supreme Ones of the Flame Emperor Domain stood imposingly, their Supreme One manifestations piercing the heavens, reaching beyond the sky, causing the myriad stars to tremble and sway.
All ages watched!
Was a Giant-Level Domain War about to begin even before the official start?
Boom— Boom—
Two other Giants from the alien race's side also emerged, displaying boundless manifestations. The River of Time manifested, swirling around them, ready to be drawn into the Supreme One domain at any moment.
"Flame Emperor, you have quite the nerve daring to enter my domain. Do you truly think this Emperor dares not deal with you?" an alien Strongest Emperor spoke, clad in emperor armor that had endured countless battles without decay, a crimson-scaled tail behind him, boundless aura radiating.
If not for the River of Time encircling this place, the vast lands of the Origin Ancient Path Domain would have long been shattered.
"Hah, do you dare?" the Flame Emperor sneered coldly, utterly unafraid.
A Giant-level battle nearly erupted.
But in the end, it did not. With the strenuous dissuasion of other Giants, it ultimately did not happen.
After all, the consequences of a Giant-level war would be far too severe, unimaginably destructive for the entire Origin Ancient Path.
Only before leaving did the Flame Emperor throw down a harsh warning: "Alien race, if you dare to sneak into my Flame Emperor Domain for any more ambushes, next time I will directly exterminate several of your Great Emperors. If you don't believe me, just wait and see."
The alien race's Strongest Emperors looked grim. This Flame Emperor was simply a tough nut, lacking much of the dignity of a Strongest Emperor, directly tearing off all pretense and speaking so bluntly, making them look bad.
However, with the Flame Emperor's fury, the alien race's hands had to be restrained, genuinely wary of this Flame Emperor.
Generally, even if such an incident occurred, with the steadiness of a Strongest Emperor, though enraged, they would not act so recklessly.
But the Flame Emperor clearly wouldn't consider too much; he would kill if he wished.
The alien race could only swallow their shattered teeth, unable to do much for now.
It wasn't that they were unwilling to act, but that they couldn't for the moment, as it wasn't the right time for all-out war.
Otherwise, given the alien race's historical dominance, they wouldn't have stopped at this.
To prevent alien infiltrators from sneaking in again, this time, the Flame Emperor personally took charge, his emperor sense covering the entire Flame Emperor Domain, and he forcefully declared that anyone from the alien race's Supreme One Domains was forbidden from entering the Flame Emperor Domain, on pain of death!
The Origin Ancient Path trembled greatly, gaining a deeper understanding of the Flame Emperor's forcefulness.
Ye Chen was moved. The Flame Emperor truly had no words for how he treated him.
Upon returning, the Flame Emperor immediately said to Ye Chen upon meeting him: "Little Chen, if a Supreme One Emperor's trace appears at the center of this Domain War battlefield, you'd best participate. The treasures inside will make your heart stir."
Ye Chen was astonished. Even the Flame Emperor spoke this way—what kind of supreme treasure could it be?
Given the Flame Emperor's status, ordinary emperor dao treasures might not even catch his eye.
Of course, the Flame Emperor seemed to say this treasure would be of great use to Ye Chen.
Although the Flame Emperor didn't explicitly state what exactly it was, Ye Chen took it to heart. If there was a chance, he must obtain it.
Two days later, with all preparations complete, the domain gate of Flame Emperor City opened. The powerhouses participating in the Giant-Level Domain War entered the domain gate, heading for the Domain War battlefield.
Ye Chen also vanished into it.
...
The Domain War battlefield was not located on the vast lands of the Origin Ancient Path, but in another world.
To be precise, it was a shattered world transferred by a Strongest Emperor using heaven-defying means from the Chaos Sea—either a shattered origin emperor world, immortal world, or chaotic primitive great world, all moved into the Origin Ancient Path and opened as a Domain War battlefield.
Generally, Supreme One-level Domain Wars used Sovereign great world-level realms as battlefields; even the more powerful ones used shattered emperor worlds or immortal worlds.
As for Giant-Level Domain Wars, they basically used chaotic primitive great worlds comparable to the Ten Heavens Ancient Domain, though also shattered.
Within the Domain War battlefield, the Flame Emperor Domain's side had long since constructed multiple ancient cities where Flame Emperor Domain powerhouses could rest and recuperate, or enter the battlefield to slay enemies.
Slaying enemies also earned corresponding points, which could be exchanged for treasures from the corresponding treasury.
Ye Chen descended upon the Domain War battlefield, gazing into the distance and sensing it was a rather shattered chaotic primitive great world. Even its world origin was nearly depleted, barely maintaining the world's stability. This was precisely why it was chosen as the Giant-Level Domain War location.
It was sufficiently large, yet devoid of any living beings, allowing for a battle without restraint.
