This deduction was made by Ye Chen based on past experience.
Since Divine Kings could possess Divine King Great Dao Origins, intents, and even heaven-defying Great Dao powers like the God King Spirit that surpassed Great Powers, wouldn't Ancient Monarchs, who stood above Divine Kings, also possess such heaven-defying Great Dao powers?
Perhaps Divine Kings were not yet qualified to comprehend them, but Quasi-Monarchs certainly were.
Just as half-step Divine Kings, Emperor Sons and Daughters, Immortal Dao descendants, and the strongest young supremes had been able to comprehend Divine King Great Dao Origins and intents back then, wasn't it the same principle?
Similarly, Quasi-Monarchs were also qualified to comprehend them.
The two Quasi-Monarchs were startled, clearly not expecting the Battle Saint King to be so astute as to have thought of this point.
Indeed, as Quasi-Monarchs, they had naturally comprehended some special powers unique to Ancient Monarchs. Though not much, it was enough to be heaven-defying and served as one of the trump cards that made Quasi-Monarchs far stronger than Divine Kings.
Hongwei Quasi-Monarch suddenly sighed. "Battle Saint King, I must say you are truly clever."
"Thank you for the praise," Ye Chen accepted the compliment without a hint of embarrassment.
In fact, if the two Quasi-Monarchs hadn't mentioned it, Ye Chen would have asked the Nigu Quasi-Monarch. Even if he was only at the early-stage Quasi-Monarch level, as an Immortal Clan Quasi-Monarch, he would naturally know quite a bit.
"Let the battle continue. I will let you experience another ultimate method of a Quasi-Monarch during the fight."
At this point, Hongwei Quasi-Monarch had no other choice but to demand a battle.
"Good!"
The great battle erupted once more, with Ye Chen facing off against Hongwei Quasi-Monarch.
The battle was fierce, and three thousand exchanges passed quickly, with blood light splattering from both sides.
Boom—
Another close-quarters collision.
Suddenly, Ye Chen felt his hair stand on end as a terrifying crisis surged from the depths of his heart.
Swish—
In a fleeting instant, the corner of Ye Chen's eye caught a flash of immortal light appearing in a split second, moving with extreme speed straight toward the Mud Ball Palace between his eyebrows. His Chaos Saint Soul avatar sensed a dreadful crisis, nearly on the verge of collapse.
At the critical moment, he instantly dodged sideways.
Pfft—
But even so, a streak of chaotic blood light shot into the sky.
Ye Chen was nearly beheaded. A deep wound, visible to the bone, was carved into his neck, and it was difficult to heal. An extremely fearsome power was grinding away the vitality of his flesh, preventing recovery.
This sent a chill down Ye Chen's spine. Was this the means of a Quasi-Monarch?
Just a fleeting instant had nearly caused him to meet his end.
It was only him; otherwise, at such close range, even if another Quasi-Monarch were in his place, they might not have been able to avoid it.
At the same time, Hongwei Quasi-Monarch closed in once more, and that terrifying immortal light flickered again.
Without a word, Ye Chen immediately retreated. The Tree of Life rooted within his body erupted with boundless life radiance, further assisted by the Life God King Spirit. Combined with the Saint Body Regeneration Technique, it forcefully eradicated the annihilating aura on the wound, reattached his head to his body, and restored his true form.
Swish—
At this moment, the Primordial Demon Giant God Soldier's war weapon, the blood-colored heavy sword, flew out and landed in Ye Chen's hand, replacing the Chaos Great Cauldron. Spirit Sword Radiance erupted, billions of sword rays soaring into the sky, carrying a torrential killing intent that swept over, engulfing Hongwei Quasi-Monarch.
However, the moment that mysterious immortal light flickered, the layers of killing sword rays were shattered, restoring clarity as Hongwei Quasi-Monarch charged forth.
Ye Chen was deeply wary and did not close in. Instead, he employed numerous divine abilities and Emperor techniques from a distance, bombarding Hongwei Quasi-Monarch to prevent his approach while also observing that mysterious immortal light.
Even his formidable Chaos Saint Body had been easily breached. Clearly, this immortal light was extraordinary and also involved the Sovereign level; otherwise, it wouldn't be so terrifying.
Whoosh—
At this moment, Ye Chen keenly sensed danger and instinctively dodged sideways the instant he felt it.
Yet his shoulder was still pierced through, blood light spurting forth.
The wound could still only be healed with great difficulty through various means.
Ye Chen was extremely wary. He stared at Hongwei Quasi-Monarch. "Is this one of the powers of an Ancient Monarch?"
He was puzzled. Why hadn't they used it when he suppressed the two Quasi-Monarchs before? Why hadn't the Sky Roc Demon Monarch, Ice Monarch, Primordial Demon Blood Monarch, or Nigu Quasi-Monarch employed it? Otherwise, the outcome could very likely have been rewritten.
But suddenly, he noticed Hongwei Quasi-Monarch's complexion pale slightly and immediately understood.
Such supreme power at the Ancient Monarch level could not be used without cost. Each use required significant expenditure of power, and there might even be some dreadful price that even Quasi-Monarchs found difficult to bear, hence it could not be used lightly.
Ye Chen also recalled that the Sky Roc Demon Monarch had only fled, while the Ice Monarch and Primordial Demon Blood Monarch had been swiftly defeated under the power of an Ancient Monarch. The Nigu Quasi-Monarch was only at the early-stage Quasi-Monarch level and knew that using it would bring more harm than good, so he refrained.
As for when he suppressed the two Quasi-Monarchs, he had employed three Giant God Soldiers along with himself, resulting in overwhelming suppression that ended too quickly, leaving no time for them to use it.
Through these various reasons, he finally understood.
Whoosh— Whoosh—
Whoosh— …
The mysterious immortal light continued to appear, not just one or two streaks, but as many as five. Each was swift as lightning, surpassing the speed of a Quasi-Monarch, making Ye Chen feel somewhat outmatched.
As time passed, Ye Chen gradually adapted and began to dodge these mysterious immortal light forces repeatedly, avoiding injury.
Seeing this, Hongwei Quasi-Monarch could only sigh silently. This Battle Saint King was truly heaven-defying beyond words.
Prolonged use of such immortal light power was also a considerable drain on Hongwei Quasi-Monarch, his complexion growing noticeably paler.
In the end, Hongwei Quasi-Monarch even voluntarily ceased his attacks.
Ye Chen stood opposite him, looking at him deeply. "What is this power?"
"Monarch Rule power!"
"Monarch Rule power?"
"That's right. At the Divine King realm, one can comprehend Divine King Great Dao Origins and intents, even fusing them into a God King Spirit. Similarly, Ancient Monarchs can also comprehend power at another level—this is Rule, which surpasses Laws," Hongwei Quasi-Monarch said solemnly, not hiding anything.
"Battle Saint King, behold the Monarch Rule I have comprehended!"
Hongwei Quasi-Monarch shouted. From his body, eight Great Dao Rules resembling brilliant immortal light surged forth—these were Monarch Rules.
Each Monarch Rule was imprinted with dense, intricate Great Dao runes, forming a special kind of rule that carried an immortal aura.
Monarch Rules belonged to the Great Dao of the Monarch level. In a sense, they were like the God King Spirit that Divine Kings could employ, but an advanced version that had become a form of Rule.
So-called Rule surpassed Laws.
Monarch Rules represented one of the most powerful forces between heaven and earth.
Laws could be altered, but Rules could not be broken!
The emergence of the eight Monarch Rules immediately emitted a powerful Sovereign heavenly might, making even Ye Chen sense a strong crisis.
