To ensure the Giant-Level Domain War could continue, this vast Domain War battlefield also contained multiple Supreme-level Great Dao imprints for stabilization and a certain degree of suppression.
This was to prevent the war from becoming too intense, especially since Ancient Monarchs could shatter Great Worlds with their might.
To avoid the collapse of the Domain War battlefield, Supreme Ones from both sides would leave Supreme imprints to maintain stability.
By the time Ye Chen arrived, many powerhouses from the Flame Emperor Domain had already gathered in the Domain War battlefield, densely packed, numbering no less than hundreds of millions, ranging from the most basic Demi-Gods to Ancient Monarchs.
However, on the distant other side of the Domain War battlefield, the opposing force engaged in the Giant-Level Domain War with the Flame Emperor Domain likely had similar numbers, perhaps even stronger.
In a Giant-Level Domain War, once one entered the Domain War battlefield, combat could commence at any time.
A typical Supreme-Level Domain War would last a hundred years.
A Giant-Level Domain War, however, would last a thousand years.
Of course, one could also leave midway.
It was also worth mentioning that any location chosen as a Domain War battlefield was typically a shattered Great World containing numerous ruins.
For instance, this Domain War battlefield, based on understanding, was originally a Primordial Chaos Great World named the Sacred Prison Great World.
The Sacred Prison Great World had once given birth to an Ancient Emperor, known as the Sacred Prison Great Emperor, who perished here along with the Sacred Prison Great World, leaving behind the corresponding Ancient Emperor inheritance.
Furthermore, the Sacred Prison Great World was once a renowned Primordial Chaos Great World in the Chaos Sea. Because the Sacred Prison Great Emperor had obtained a certain peerless treasure in the Chaos Sea, coveted even by Supreme Ones, three Supreme Ones eventually came for that treasure alone. This led to the outbreak of a Supreme battle, ultimately causing the Sacred Prison Great World to disintegrate and shatter, becoming a ruin in the Chaos Sea.
The three Supreme Ones from that time perished as a result, once shaking the entire Chaos Sea.
Therefore, within the Sacred Prison Great World, there were at least the traces of four Supreme Emperors.
As for the followers of those four Supreme Ones who participated in the battle back then, countless also perished within, which for many represented a tremendous opportunity.
Similarly, many also wondered what exactly that peerless treasure was, for which the four Supreme Ones were willing to fight to the death.
Ye Chen's heart stirred. Could this peerless treasure be the very treasure Flame Emperor had mentioned?
Before the Domain War commenced, the Flame Emperor Domain's army, led by multiple Ancient Monarchs, held an exceptionally large oath-taking assembly, greatly boosting the morale of the Flame Emperor Domain's powerhouses. Everyone was filled with hope.
The younger generation of geniuses were even more fervent, eager to join the battle immediately.
After the oath-taking assembly, Ye Chen did not immediately venture deep into the Domain War battlefield to kill enemies for corresponding points or search for the Supreme Emperor traces within. Instead, he entered seclusion once more.
Through the events in the Drunken Immortal Pavilion's starry space, he felt that although his own strength was already formidable, there was no guarantee that the alien race wouldn't send even more terrifying opponents to target him this time. Therefore, before participating in the Giant-Level Domain War, he chose to enhance his strength once again.
He began refining and devouring the World Origins of the five Ancient Monarchs, along with those of the three Monarchs.
It could be said that this time, Ye Chen intended to completely refine the World Origins of the five Sovereigns successfully before truly emerging from seclusion.
...
The Sacred Emperor Domain, ruled by the strongest Emperor, Sheng, was also the opposing side in this Giant-Level Domain War against the Flame Emperor Domain.
Sheng, the strongest Emperor of the alien race.
Originally located in the alien race's Ancient Universe, he had chosen to descend upon the Primordial Path of Origins this time.
The failure of the assassination attempt on the Battle Saint King had caused heavy losses for the alien race, forcing them to change their plans.
However, the assassination of the Battle Saint King must proceed no matter what.
At this moment, the Supreme Ones under Sheng exchanged Divine Thoughts.
"Everyone, this Emperor has heard that the Battle Saint King is participating in this Giant-Level Domain War."
"Good. The failed assassination in Flame Emperor City last time caused us heavy losses. No matter what, we must ensure that Battle Saint King remains forever on the Domain War battlefield."
"Although the news was suppressed, it is understood that in the Drunken Immortal Pavilion's starry space, the Battle Saint King initially fought five Ancient Monarchs alone. Although they were merely First and Second Heaven Ancient Monarchs, it is enough to prove that in the short span of a year, the Battle Saint King's strength has increased significantly—from originally needing to exert full force to suppress a First Heaven Sovereign to now being capable of suppressing multiple Sovereigns, including Second Heaven Sovereigns."
"This youth's potential is too terrifying. He seems to still be in the Quasi-Sovereign realm. Once he becomes an Ancient Monarch, it would be unthinkable."
"We must nip this youth in the bud early. Otherwise, once he grows up, the consequences would be unimaginable!"
"But ordinary Supreme Ones might not necessarily be able to kill the Battle Saint King, and would Flame Emperor simply stand by and watch us deal with him?"
"Take advantage of the Giant-Level Domain War battlefield. Although Supreme Ones cannot act, Monarchs are not restricted. Let a Monarch take action."
"A Monarch? Isn't that too risky? If discovered by Flame Emperor, he would likely spare no effort to kill the Monarch. The loss to our side would be too great."
A Supreme One frowned. Monarchs were Quasi-Supreme, Quasi-Emperor existences. Although not guaranteed to prove the Dao and become Supreme, they at least represented such potential, their importance far exceeding that of Ancient Monarchs.
Although the Battle Saint King's potential was immense, even comparable to the Primordial Ancestor and Heavenly Emperor in their youth, he had not yet grown to their level.
If sacrificing a Monarch's life to kill this Battle Saint King, the cost would be far too great.
Many Supreme Ones frowned.
Finally, the strongest Emperor, Sheng, spoke: "Approved!"
A Monarch might hold great importance, but compared to a Battle Saint King with infinite potential to grow to the level of the Primordial Ancestor and Heavenly Emperor, it might not necessarily be comparable.
Anyone could see that as long as the Battle Saint King did not die, he would at least reach the Monarch level in the future.
Perhaps he could not prove the Dao and become Emperor through the Chaos Great Dao, but who said one could not rival a Supreme One without proving the Dao and becoming Emperor?
The Formless Monarch was still a Monarch, yet he was no weaker than a true Supreme One.
Back then, to kill the Formless Monarch, sacrificing two Monarchs and seven peerless Sovereigns was deemed acceptable.
Now, to kill a potential enemy with even more terrifying potential than the Formless Monarch, what was sacrificing one Monarch?
With the strongest Emperor, Sheng, speaking, no one dared to oppose. The decision was unanimously passed.
During the Giant-Level Domain War, a Monarch would take action to assassinate the Battle Saint King.
...
In the Sacred Prison Domain War battlefield, on the Flame Emperor Domain's side, Ye Chen was unaware that the Sacred Emperor Domain was willing to sacrifice a Monarch to deal with him.
At this moment, he was in seclusion.
The Giant-Level Domain War had long since begun, but he had not participated, choosing instead to enter seclusion to devour and refine the World Origins of the five Ancient Monarchs.
With his cultivation reaching this level, his strength no less than a Second Heaven Sovereign, his speed of devouring and refining naturally far surpassed the past.
In just five months, he successfully emerged from seclusion.
His strength had increased by another significant margin.
