From the outside, attacking and breaching a war city was no simple feat. Even cultivators at the Dao Platform Realm couldn't easily tear through the defenses. Even Innate Spiritual Treasures would struggle to forcefully break in. If such a battle were to occur, the resulting energy fluctuations would be impossible to conceal—any outside observer would immediately detect them.
Thus, the most likely scenario was an attack launched from inside.
This theory was proposed by a renowned Eternal Night strategist.
Naturally, this made the theory all the more credible.
Many top cultivators made deductions of their own and agreed—it made perfect sense.
Soon after, war cities across the Eternal Night battlefield entered a state of high alert. All formations and barrier enchantments were set to a semi-active state, ready to erupt at a moment's notice. The number of guards at the gates increased tenfold, and at every city entrance now hung a mirror called the Night Demon Mirror.
This artifact had one sole purpose: to detect lifeforms not native to Eternal Night.
The native beings of Eternal Night carried a unique aura. The Night Demon Mirror would remain inert in their presence. But if a being from the Eternal World approached, it would emit a bright glow, lighting them up like a beacon in the darkness.
Of course, this was not foolproof—it was only the first line of defense. Within the cities themselves, powerful cultivators were hidden, lying in wait. If an intruder revealed themselves, it would be like walking into a trap—inescapable.
The only reason Yi Tianxing had succeeded before was because of complete surprise. The Eternal Night factions had never even considered the possibility of being attacked themselves.
But now?
Now that they were on guard, no one could simply infiltrate a fortress from within.
Eternal Night's races were not to be casually humiliated.
Meanwhile, in the Eternal World – Divine-Demon Battlefield.
Floating among the stars of the void, one could see mighty figures seated atop massive celestial bodies. These were the prodigies of Eternal Night, each exuding an aura as deep and vast as the abyss. Every one of them was like a divine being—gazing down upon all beings from the heavens.
Yet at this very moment, a piece of news caused the glow from those stars to dim.
"Someone actually invaded our Eternal Night battlefield!?Who has the guts?How did he get past our defenses?"
"Three entire war cities vanished without a trace?That kind of feat... can only be done by a top-tier powerhouse."
"Shameful. Utterly shameful!We've been battling at the frontlines, and someone backdoored our homeland!What a slap in the face!"
"I can't stand this. I'm going back.I'll catch that bastard, skin him alive, and use his soul as a lamp!"
"Find him! Anyone who dares invade Eternal Night must be a supreme genius.Investigate! Who the hell has the nerve to pull this off?"
The Eternal Night prodigies, stationed across the Divine-Demon Battlefield, were all fuming.
While they fought bloody battles at the frontlines, someone had invaded their home.
This news made their blood boil.
But most also believed the culprit likely came from the Eternal World.
So the investigation began on the battlefield.
"The demonic genius Stone Emperor of the Saint Spirit Clan was seen on the Void Battlefield two days ago—it can't be him."
"The Flawless Immortal of the Celestial Spirit Clan made an appearance yesterday and took action. It was definitely him—not someone else."
The Eternal Night prodigies swiftly exchanged thoughts via divine sense, filtering through the possible suspects.
Their intelligence network was extensive. Every major figure on the battlefield had been carefully monitored and recorded.
Until finally…
"Wait. Emperor Yi is missing.Yi Tianxing hasn't appeared in days.He didn't join the nightly assaults, nor was he spotted in daytime skirmishes.It's like… he vanished from the Divine-Demon Battlefield."
"It's him. It has to be him!"
"Damn it! Yi Tianxing actually had the gall to infiltrate our Eternal Night battlefield?Absolutely outrageous!"
"Good. Very good.Since you dared to enter Eternal Night…Then die here!You rejected the road to Heaven, and barged through the gates of Hell."
"Killing Yi Tianxing is worth more than slaying a billion Eternal World cultivators.We cannot let him run rampant on our lands.This time, we'll make him understand:Eternal Night is not to be trifled with."
After eliminating all other suspects, the prodigies immediately locked in on Yi Tianxing.
Some had already sensed that something was off these past few days.
Now the pieces clicked into place.
Yi Tianxing was not absent—he had invaded Eternal Night.
This realization struck a deep chord in every Eternal Night prodigy.
They could not tolerate this.
If Yi Tianxing didn't die, it would be a thorn in their hearts forever.
Their frontlines had been breached. Their homeland violated.
This disgrace was too much to bear.
Shua shua shua!!
In the starry void, one star after another dimmed—some even vanished completely.
"Damn it! Wait for me, you bastards!Trying to hog all the glory?!We've been left behind!"
Roughly half of the Eternal Night stars dimmed—clearly, their prodigies had left.
But not all of them could return.
The Divine-Demon Battlefield still required oversight. Abandoning it entirely would lead to disastrous consequences.
If the war shifted unfavorably because of this, they couldn't bear the wrath of the higher-ups.
So in the end, only the quickest returned to Eternal Night.
"What's going on?So many stars just disappeared.Is Eternal Night plotting something?"
In a war city of the Eternal World, the Stone Emperor raised his eyes toward the void.
He had immediately noticed the change.
Everyone knew those stars were actually gates created by Eternal Night—Night Gates. Their sudden disappearance was suspicious.
"Alert the others.Keep everyone on guard.Something's definitely brewing."
Other alien race cultivators noticed the change too, issuing similar warnings.
High atop a mountain.
The Longevity Daoist and Carefree Wanderer stood side by side, gazing into the skies. Their eyes flickered with a mix of awe, concern, and expectation.
"Fellow Daoist, it seems Emperor Yi has passed through the Well of Gods and Demons and entered the Eternal Night battlefield.And now, he's caused quite a stir.Those Eternal Night prodigies are returning to deal with him," Longevity Daoist said slowly.
"Indeed. I thought he'd fail at the Well's threshold.But he not only made it through—he's stirred up a hornet's nest.If he truly causes upheaval, it might benefit our Eternal World forces.I only pray… that he comes back alive.If not, it would be a huge loss for our side," Carefree Wanderer sighed.
The return of so many Eternal Night prodigies only proved how much they feared Yi Tianxing.
They wanted him dead at any cost.
"Don't worry.With Emperor Yi's capabilities—and the Great Divination Celestial Umbrella—he should still have a chance.No news is the best news," Longevity Daoist said with a smile.
At this point, optimism was all they could hold onto.
At that moment, in the Eternal Night battlefield...
Yi Tianxing was nowhere to be seen on the surface.
Instead, he was inside the Primordial Emperor Tower, standing within one of its inner worlds.
Before him stood three entire war cities.
Each was massive enough to house millions, even tens of millions of inhabitants.
He was currently inside Bloodflame City, standing before its Summoning Pool.
Beside him were Liu Bowen, Zhuge Liang, and other key figures. Even Yao Yue and her companions were present.
All of them were studying the Summoning Pool with deep curiosity.
"Your Majesty, this Summoning Pool is truly extraordinary," Liu Bowen said in awe."Its array formations, its core—the Chaos Demon Stone—they're flawless.Absolutely seamless.It devours the power of desire and uses it to spawn slave soldiers.Unbelievable.Even more mystical than the Divine Bloodline Tree."
Indeed, the Summoning Pool had become a key subject of study.
Even with their formidable intellect, they could only grasp fragments of its inner workings.
Replicating it? Impossible.
Not just due to the Chaos Demon Stone—more so because of the complexity of the formation inscriptions.
Of course, destroying it was easy.
But repairing it after? Practically unthinkable.
"Can we modify the imprint within and make it serve us?" Yi Tianxing asked seriously.
That was the most crucial point.
"Yes," Zhuge Liang nodded."The slave soldiers spawned by the Summoning Pool are infused with desire and bloodlust.The root of this lies in the blood essence used—which contains a soul imprint compelling them to obey Eternal Night and attack Eternal World forces.If we can reverse that imprint, they will serve Da Yi instead."
