Crimsonflame Demon Lord was consumed by despair.
He couldn't even get close to the Nine-Dragon War Chariot.
The sky was ablaze with Heavenfire, and the entire demon city had turned into a furnace. Having been ambushed within its walls, and without the protection of its defensive formation, Bloodflame City had become a death trap—a pot waiting to boil.
Even domain powers were useless before the Heavenfire. Not even teleportation could escape the spatial suppression of the gate.
But perhaps the most devastating truth was this:
No one in Eternal Night had ever imagined that someone would invade them.
Not in this era, at least.
The last time something like this happened... was in the previous epoch.
Now, it was happening again.
It was a premeditated strike against unprepared foes. There was no room for accidents.
The Blood Demons' domains usually manifested as blood seas, but those were naturally countered by fire. Even if they could manifest it now, the Heavenfire would vaporize it instantly.
The million-strong Divine Crow Legion had condensed the Heavenfire Tree, and the fire it rained down was so overwhelming that even a True Spirit Realm expert like the Crimsonflame Demon Lord couldn't resist it.
He was trapped in a sea of fire—his Blood Sea Domain shrinking rapidly, evaporating under the flames. The moment the fire touched his body would be the moment of his death.
"What you Eternal Night fiends have done in my Eternal World—this... this is merely the interest.Worry not. There will be more of you joining them in the afterlife.No—your very souls shall belong to me.All your souls shall be my nourishment."
Yi Tianxing smiled faintly, his voice calm.
With a single thought, his Innate Yin-Yang Eyes began to operate.
His pupils gave rise to black and white spirals, twisting in constant rotation.
Invisible devouring power surged forth—enveloping all of Bloodflame City in an instant.
"Ahhhhhh!!"
Screams echoed as countless demonic souls were forcibly drawn from the void—ensnared by black-and-white rings and sucked into his eyes.
They streamed endlessly into his Yin-Yang Domain.
Tens of thousands, then hundreds of thousands, even over a million blood demon souls were devoured.
Once inside the Yin-Yang Domain, they were dragged into the Innate Yin-Yang Divine Diagram and reduced to pure soul essence.
Inside the diagram, the four divine abilities—Yin-Yang Lock, Yin-Yang Shears, Yin-Yang Mirror, and Yin-Yang Bottle—were glowing intensely, bathing in divine light. Intricate patterns began to shift and evolve on them.
Law and Dao resonance rippled in all directions.
Suddenly—
Shing!
A new wave of black-and-white divine light surged, and within the diagram, the compressed soul essence began to mutate.
The change came swiftly—natural, yet earthshaking.
Rune after rune flickered. Principles shifted. The entire space began to resonate.
"This... The Innate Yin-Yang Life Aperture is about to birth a new innate divine ability!"
Yi Tianxing's eyes flickered in surprise and anticipation.
He hadn't expected the Life Aperture to evolve now, though it made sense—the years of effort refining the Yin-Yang Eye, absorbing not only Yin and Yang energy but also countless soul essences, had built an immense foundation.
More recently, during the war in the Divine-Demon Battlefield, he had fed many demon souls to the Bone Crow Clan, but still reserved a great share for tempering the Yin-Yang Eye.
Now, the devouring of Blood Demon souls within Bloodflame City had pushed the aperture to a critical threshold.
It was time for evolution.
"What kind of divine ability will it produce this time?"
Even with his stoic heart, Yi Tianxing couldn't help but feel excited.
The Innate Yin-Yang Eye was an unparalleled pupil technique, an Aperture with nearly limitless potential. The stronger it became, the greater its role on the battlefield.
He focused entirely inward.
The Yin-Yang Divine Diagram surged with power.
When the divine light reached its climax, the runes merged—forming a single primordial source.
Then—
It materialized as a massive black-and-white grindstone.
Black rotated counterclockwise, white spun clockwise. They turned in unison, Yin and Yang interweaving into chaotic destruction.
A force that could grind all things into dust.
"This is the divine ability—Yin-Yang Grindstone!!"
Yi Tianxing immediately understood its origin.
This was a supreme killing technique—a manifestation of Yin-Yang laws.
Once activated, the rotating grindstone would form a swirling Yin-Yang vortex, sucking in everything around it and reducing it to powder. Nothing could withstand it.
It was terrifyingly brutal, overwhelmingly tyrannical—a divine art that could destroy entire worlds.
BOOM!!
Suddenly, the entire Yin-Yang Domain transformed.
Within it rose a law pillar—a towering structure that connected heaven and earth.
It was none other than the Yin-Yang Law Pillar, supporting the domain itself.
Yi Tianxing saw that 60% of the pillar had already solidified, with the remaining 40% still in flux.
At its base was the Yin-Yang Divine Diagram, spinning endlessly, sending ripples of Yin-Yang law into the pillar.
Around the pillar:
Yin-Yang Locks slithered like serpents,
Yin-Yang Shears danced like dragons,
Yin-Yang Bottles shimmered with divine brilliance,
Yin-Yang Mirrors reflected everything.
Now, the newly formed Yin-Yang Grindstone joined them, absorbing Dao essence and refining itself in the light of laws.
As it fused with the Law Pillar, strands of black-and-white Yin-Yang Dao Rhythms emerged from the void, flowing into the pillar.
The illusory parts began to solidify at an astonishing rate.
In the blink of an eye, the pillar's solidified portion reached 70%.
"Seventy percent..."
Yi Tianxing's spirit surged.
His consciousness merged with the pillar, bathing in the sea of Yin-Yang principles. Endless comprehension flooded his mind.
Words couldn't capture the profundity of it.
Each of the five Life Aperture divine abilities was evolving—becoming almost tangible, their power greatly enhanced.
Divine abilities were ultimately manifestations of laws, and the stronger the Law Pillar, the stronger the divine power.
"With the Law Pillar at seventy percent, I now match True Spirit Realm experts.And with the Yin-Yang grindstone, I can even surpass them. I might truly be able to fight above my level now."
Yi Tianxing's heart was elated.
This was nothing less than a heaven-sent opportunity, a divine transformation.
Even the Yin-Yang Domain had expanded more than tenfold.
The Yin-Yang Eye continued absorbing Blood Demon souls, refining them into divine nourishment.
And the Yin-Yang Eye itself still harbored other powers:
See through Yin and Yang,
Pierce through Heaven and Earth,
Its vision could scan Nine Heavens and Nine Hells.
Once perfected, it would even outclass legendary Fiery Golden Eyes.
By now, the Crimsonflame Demon Lord had been reduced to ashes.
Even his soul couldn't escape—swallowed, refined, and utterly erased by the Yin-Yang Eye.
"Emperor, the Blood Demons in the city have been completely exterminated."
Mu Guiying's report cut through the silence.
"Good. Return to base."
Yi Tianxing nodded calmly.
Their base was the inner world of the Primordial Emperor Tower—a realm known only to him. The safest place during this Eternal Night campaign.
The Divine Crow Legion stepped back through the Spatial Gate.
No casualties.
They had annihilated a demon city without a single loss.
Of course, this was an unrepeatable miracle—made possible by catching the enemy off guard.
"Now... devour it!"
After retrieving his forces, Yi Tianxing turned to the now-silent Bloodflame City.
With a flash of light, the Primordial Emperor Tower appeared in his hand.
From its peak, a purple divine ray spread outward, blanketing the entire city.
BOOM!!!
In the next instant, the divine light retracted—pulling everything into the tower.
The entire process took less than a breath.
Bloodflame City vanished without a trace.
Only a giant crater remained.
All buildings—gone.
The city had been absorbed into a tower world, becoming one with it.
With a casual wave, Yi Tianxing retrieved the Heaven-Sealing Umbrella that had cloaked the battlefield.
"This... is only the beginning—not the end."
He whispered, turning without hesitation and heading toward the next demon city.
He had no time to lose.
Before word of this spread—
—he would destroy as many cities as he could.
