But King Xia had actually cleaved through his palm strike head-on?

"Could it be…"

The Nightmare Demon God immediately had a suspicion in his heart, "Was he forced to Harmonize? Forced Harmonization, and it's this powerful? The Ultimate Path is this terrifying?"

The Daoist Ancestor remained calm.

Meanwhile, beneath that vast world projection, an aura began to surge at an astonishing speed. Originally, the aura of a Great Cultivator was already extremely strong, but now it had directly broken through that boundary!

In just the blink of an eye, the aura became so terrifying that even the Nightmare Demon God felt a bit of fear.

"The Ultimate Path, and forced Harmonization is this strong?"

The Nightmare Demon God looked incredulously at where Lin Yue stood, filled with disbelief.

No one had ever seen the legendary Ultimate Path.

Even in the Ancient Times, those who succeeded in Harmonization with the Ultimate Path were rare, aside from the Primal Divine Race and the three children of the Primal Era; the Ultimate Saints were exceedingly few.

Only from myths and legends could one find any descriptions.

No one had ever seen the power after Harmonization with the Ultimate Path.

But to deal with a Saint who hadn't even transcended yet, even with the Ultimate Path, he, a dignified Demon God, was at a disadvantage?

"Do not worry."

The Daoist Ancestor transmitted, "He is already at his last gasp. According to the information obtained from the past by the Prison Demon God, those who force Harmonization with the Ultimate Path often have very crude Cultivation Techniques. Thus, most of them collapse with their Divine Souls dispersing at the moment of Harmonization. Lin Yue has no real source for the Inner Heaven and Earth Cultivation Method of the Ultimate Path, relying only on his self-created Cultivation Technique… this is likely his last brilliance."

"Logically, at the moment of Harmonization, his Divine Soul should collapse and disperse." The Nightmare Demon God exclaimed, "Yet he can still manage to attack?"

He was not only surprised by the terrifying power of the Ultimate Path, but also shocked that Lin Yue wasn't instantly dead.

"Isn't our being here precisely to prevent this situation?"

The Daoist Ancestor shook his head slightly.

The Demon Clan was also worried that this King Xia would be overly unfathomable, creating a rather exquisite Inner Heaven and Earth Cultivation Method with no precedent, so they invited the Daoist Ancestor and the Nightmare Demon God to take action together.

To crush any vitality and possibility!

"Boom—"

In just an instant, the starlit saber light sweeps across, shattering the Nightmare Demon God's world projection. The enormous world projection instantly collapses and disperses.

At the same time, a terrifyingly fast streaming light pierced through the void, rushing towards the two!

In the streaming light, it was clearly Lin Yue, whose aura had already surged to its Peak!

"Kill!"

Lin Yue's gaze was cold, carrying a hint of madness. At this moment, his body housed a chaotic and void Inner Heaven and Earth slowly evolving, granting him an unimaginably frightening power.

Although he hadn't formed a truly perfect Ultimate Heaven and Earth, facing a desperate situation, he could only force Harmonization!

His Divine Soul was destined to collapse.

This was almost a path of certain death.

But as the cost, he had gained the true combat power of the Ultimate Path!

"Kill! Fight your way out!"

Lin Yue's mind was now filled only with icy killing intent, forgetting any other consequences, leaving only one thought:

"As long as I kill them, I have a chance of surviving!"

The frightening power of the saber light flashed, erupting suddenly, transforming once more into raging torrents of starry river surging out!

"He can still attack?"

The Nightmare Demon God's expression changed, having to transform into a nightmare form, instantly scattering and floating away.

Among the Demon Gods, he was at best mid-tier.

Even though the current Demon Gods could refine Divine Power, he had only just begun, much lesser compared to those who had perfected Divine Bodies or even mastered Divine Hearts like the Ancestors of the Demon Clan.

Under the terrifying saber light filled with Lin Yue's murderous intent, his world projection collapsed directly, needing time to reconsolidate, so he dared not meet the attack head-on.

He could only avoid the edge with his nightmare avatar's Undying Body temporarily.

At the same time, he transmitted, "Daoist Ancestor, did you not say his Divine Soul would collapse immediately? Block him now!"

The Daoist Ancestor sighed softly and pointed lightly with his fingertip.

Strands of radiant brilliance and shadows converged into swimming fish, instantly rotating to form a massive Tai Chi, attempting to suppress Lin Yue within it.

A world was an endless force furnace; even the simplest Daoism here was a supreme Dao Skill returned to its true form!

"Daoist Ancestor?"

Lin Yue's golden armor was driven to the utmost, with Wind and Thunder Wings crazily channeling wind and thunder behind him, and Flying Spirit Chasing Sun underfoot transforming into flames spinning madly.

These Semi-Divine Artifacts, which initially required the Proving Realm to fully unleash, could be driven to the fullest extent by him after Harmonizing with the Ultimate Path!

In an instant, he vanished from the void, leaving the immense power of the Tai Chi Diagram enveloping nothing.

"Boom!"

When Lin Yue appeared again, he sliced out a saber strike towards the seemingly illusory and non-existent nightmare Undying Body in the void!

This time, the saber light didn't transform into the starry river; just with the stars glistening briefly, the horrifying Sword Intent seeped into the illusory black mist, following the infinite intangible connection, starting a mad slaughter!

"No!"

The Nightmare Demon God let out a cry of fear and incredulity as the scattered nightmare Undying Body began to coalesce, turning into a pale-faced, noticeably weakened Nightmare Demon God.

He had thought this nightmare Undying Body was more than sufficient for survival, perfectly countering such pure physical assaults.

But who would have thought this Divine Artifact Battle Saber would be so fearsome, its terrifying Sword Intent directly annihilating his lifeline through the intangible connection following the scattered nightmare Undying Body!

In just one saber strike, over fifty percent of his life force was obliterated!

Even taking a direct blow would not have resulted in such severe damage, startling him back into restoring his True Body immediately.

"Daoist Ancestor, that Divine Artifact Battle Saber completely counters my Undying Body," the Nightmare Demon God transmitted, "I can only resist; make more attacks, or I can't block a few more saber strikes…"

"It matters not; his Divine Soul is about to collapse. He should not be able to unleash many more saber strikes." The Daoist Ancestor transmitted back.

The Nightmare Demon God was somewhat terrified.

Earlier, it was said that his Divine Soul would collapse immediately, yet Lin Yue was still able to fight!

How many strikes does he need to endure before Lin Yue's Divine Soul collapses?

"I can hold on for about thirty breaths…"

Lin Yue's eyes were ice-cold, staring firmly at the Nightmare Demon God, "I can't kill the Daoist Ancestor now… Before I risk my life, I must at least kill the Nightmare Demon God!"

The speed of his Divine Soul's collapse was much slower than the Daoist Ancestor and the Nightmare Demon God had anticipated.

Because after obtaining the Inner Heaven and Earth Cultivation Method from the wish of the bygone days, he immediately created his Inner Heaven and Earth Cultivation Method using the Heavenly Dao Heart.

Though imperfect, it still had seventy to eighty percent of the true Ultimate Heaven and Earth essence.

In the past, indeed, at the moment of Harmonization, he would have perished with his Divine Soul collapsing, possibly without even the opportunity to attack.

And now…

Even if each full-strength activation of the Ultimate Heaven within would increase the collapse of his Divine Soul, he could still sustain it for more than thirty breaths before the collapse occurred!

If he didn't activate the Inner Heaven and Earth, calmly recuperating, the collapse of the Divine Soul would be much slower.

But with the Daoist Ancestor and the Nightmare Demon God present, he couldn't refrain from activating it.

So—

"The only path to survival is to kill them!"

The Inner Heaven and Earth, evolved from the Ultimate Path, operated almost at its limit, as Lin Yue's Divine Soul veered toward collapse, transforming into a terrifying power.

"Die!"

The saber light crisscrossed, the starry river roared.

Being the Daoist Ancestor, his full efforts in obstruction made it much harder for Lin Yue to bypass and kill the Nightmare Demon God.

But the Ultimate Path was, after all, the Ultimate Path, without flaws. In terms of height, it was no less than the Daoist Ancestor's realm of Proving and Transcending, while in terms of breadth, it far surpassed.

Therefore, despite the Nightmare Demon God's evasion, he couldn't avoid being hit by Lin Yue's saber light.

The most crucial factor was—once the Star Temple sealed, all isolation was severed, and any Avatar methods were ineffective; even a nightmare Divided Being left outside the Temple couldn't allow him to revive.

This place was like a cage for trapped beasts; initially, he thought King Xia had his path cut off, but it turned out it included himself too.

"Boom! Boom! Boom!"

The raging saber light continued to erupt within the desolate Star Temple, the soaring killing intent unstoppable, descending like a mad storm.

"No!"

"Why isn't he dead yet?!"

"Daoist Ancestor!"

"This… it can't be! Just a Great Cultivator forced into Harmonization!"

"Why? Why hasn't his Divine Soul collapsed yet!"

"No… am I to die like this?"

"Hahaha… so be it, so be it, you will die too, you will die too… King Xia, I go first!"

In just twelve breaths, the Nightmare Demon God was utterly extinguished, vanishing without a trace, amidst the skyrocketing saber light's slaughter.

An era of Demon God thus fell.
