It could be said that even a peerless Sovereign like the Kunxu Ruler could do nothing against him.
One-on-one, Ye Chen was invincible under heaven.
It was precisely because of his extreme fearsomeness that the Five Forbidden Zone Masters had united from the very beginning.
At this moment, the other three Forbidden Zone Masters also desperately attacked Ye Chen, attempting to kill him.
Another one among them was also a peerless Sovereign like the Kunxu Ruler.
Of course, also like the Kunxu Ruler, he had suffered the most terrifying injuries from the Dominator-level battle thirty years ago, wounds that remained unhealed to this day, allowing him to exert less than sixty or seventy percent of his peak strength.
*Splat*—
In the end, even someone as powerful as Ye Chen could not be completely invincible. After all, his dao techniques were completely sealed. What he could mobilize was essentially only the power of his Chaos Saint Body; he could not be truly invincible in the absolute sense.
Multiple wounds appeared on his body, and Chaos Saint Blood dripped down, containing unimaginable power.
Yet Ye Chen's expression never changed. These injuries were simply not worth mentioning compared to those from thirty years ago.
He let out a slight sigh and said, "Is this all the strength you have?"
Ye Chen's exposure was precisely because he wanted to use their power to shatter the Great Dao Heavenly Diagram within him. But now it seemed that wouldn't work either. Even if they wanted to severely wound him, it was difficult, let alone shatter the Great Dao Heavenly Diagram, which required the power of a Ninth Heaven Sovereign with over ten million Monarch Rules.
The power currently attacking him was still far from enough.
Deeply questioned by their enemy, the Five Forbidden Zone Masters were utterly enraged. This was clearly not taking them seriously.
One by one, they unleashed terrifying offensive techniques again, continuously and forcefully assaulting Ye Chen, even attempting to inflict fatal wounds upon him.
However, they soon discovered a shocking fact.
Not only was Ye Chen's fleshly body indestructible, but the speed of his injury recovery was also terrifyingly fast beyond imagination. His wounds healed rapidly, to the point that, despite expending who knows how much power, they still could not inflict any effective damage on him.
It was as if a cat was toying with mice. From beginning to end, they were being played with by the Heavenly Kingdom Ruler.
"Ah—"
One of the Forbidden Zone Masters finally could bear it no longer. With a roar, he risked the possibility of his injuries erupting, pushing himself to the limit to temporarily restore his peak state by suppressing his wounds.
A world-shaking aura erupted. A million Monarch Rules manifested—this was the strike of this Forbidden Zone Master at his peak, a thunderbolt-like assault on Ye Chen.
At the same time, the other Forbidden Zone Masters did the same. Even the Kunxu Ruler and the other peerless Sovereign-level Master acted similarly. Their imposing might rose level by level, surpassing everything. The combined number of Monarch Rules they unleashed actually reached a full eight million, all striking Ye Chen together with immense force.
*Boom*—
Ye Chen's figure was sent flying, crashing into the borderlands of the Mythical Ruins Land, but he was not shattered to pieces.
While part of the reason was that his Chaos Saint Body was superior to before, the more important factor was that, at the critical moment, the Great Dao Heavenly Diagram manifested, neutralizing the vast majority of the attack power.
It could be said that when external force reached a certain level, while sealing his dao techniques, the Great Dao Heavenly Diagram would also manifest, transforming into a heavenly diagram armor to protect him.
In a sense, this was equivalent to a Ninth Heaven Sovereign's battle armor. To break through this layer of armor required the power of a Ninth Heaven Sovereign.
"Hahahaha—"
Ye Chen threw his head back and laughed uproariously, soaring into the sky and charging back into the fray. He continuously unleashed Chaos Saint Fists, roaring with laughter, "Thank you! The endless stream of Monarch Rules you poured into me back then, along with the Great Dao Heavenly Sun of the Ancient Heaven Realm, may have sealed my cultivation, but they have also become my immortal battle armor. As long as this armor remains unbroken, killing me will be countless times more difficult for you."
The faces of the Five Forbidden Zone Masters all changed, and regret also surfaced. Their attacks from back then had now become their enemy's greatest protective armor. It was utterly ironic, a blatant slap to the face, leaving them feeling utterly helpless.
Now, to truly kill the Heavenly Kingdom Ruler, they would first have to break the seal of his Great Dao Heavenly Diagram.
The Five Forbidden Zone Masters exchanged glances, deeply frustrated. While dealing with the Heavenly Kingdom Ruler's assaults, they had no choice but to think of a solution.
To kill their opponent, the first thing they had to do was break the seal of the Great Dao Heavenly Diagram, allowing him to fully return to his peak.
But at the same time, this would also present an opportunity to kill him.
However, the risk of doing so was also extremely great. They had witnessed the awe-inspiring power of the Heavenly Kingdom Ruler thirty years ago. Facing the attacks of over a dozen Dominator-level powerhouses, he had still managed to counter-kill several and severely wound the rest, even returning from death thirty years later.
All of this proved his severe threat.
Now that they had finally managed to seal him, they absolutely could not undo the seal of the Great Dao Heavenly Diagram.
Of course, if they didn't undo it, the Great Dao Heavenly Diagram would remain his best protective armor, making killing him an extremely difficult task.
It was precisely because of this that they had to deliberate carefully.
While dealing with Ye Chen's attacks, they agonized over whether to undo the seal of the Great Dao Heavenly Diagram or not.
*Boom*—
Silently and without warning, Ye Chen appeared before one of the Forbidden Zone Masters. His imposing might was at its zenith, comparable to ten thousand thunderbolts. In this vast world, what could possibly block him? He swept through everything.
In an instant, a forbidden ancient weapon was utterly shattered, and countless fragments were sent flying, embedding themselves into the bodies of several Forbidden Zone Masters, splattering large amounts of blood.
"Since you're considering it, let me help you out first by killing you."
A leg swept out. With a thunderous crash, another Forbidden Zone Master was sent flying toward the horizon.
Then, with his left hand executing Heaven-Shaking Palm and his right hand Heaven-Severing Finger, he clashed with the two peerless Sovereign-level Forbidden Zone Masters.
*Boom boom boom*—
His figure was sent flying hundreds of millions of li, but the two Forbidden Zone Masters were also blasted back millions of li.
"Sky-Overturning Seal!"
A furious shout echoed. It was Ye Chen, seizing the advantage to pursue, actively charging back. Appearing in mid-air, he overlapped his left and right hands, transforming them into a vast, sky-propping giant seal. It overturned heaven and earth, its power immeasurable, crashing down as if intending to utterly shatter the entire Mythical Ruins Land.
The several Forbidden Zone Masters were horrified. It seemed they hadn't expected that, even at this point and with his dao techniques sealed, the Heavenly Kingdom Ruler still possessed such unimaginable combat power.
The Five Forbidden Zone Masters resisted together, forcefully blocking the Sky-Overturning Seal. Then, all five of them reached the same decision.
Kill!
Even if it meant undoing the seal of the Heavenly Kingdom Ruler's Great Dao Heavenly Diagram, they had to kill him.
Otherwise, with that Great Dao Heavenly Diagram protecting him, he would be innately invincible. Over time, they would be the ones killed.
Furthermore, the vast Ancient Heaven Realm wasn't just them targeting the Heavenly Kingdom Ruler. There were others who targeted him even more intensely, harboring an irreconcilable life-and-death enmity.
