He has been reincarnated through countless worlds, adorned with billions of mythological terms!

Just as the palm strike was about to land, that lifeless world suddenly lit up for a moment.

Light seeped out from the densely corroded cracks in the world's walls, lasting for less than a breath, before the entire world's remains suddenly became completely transparent before Yun Yi's palm strike landed.

The palm strike pierced through the void, unleashing a shockwave that stretched for billions of miles, shattering all the floating debris into dust—yet the world's remains itself unharmed.

Yun Yi raised an eyebrow slightly.

Although this palm strike was just a casual blow, the yin energy it contained was enough to turn the true form of an evil god into mincemeat.

This death world, with its laws withered, its energy depleted, and even its spacetime completely frozen, was able to react before his palm strike arrived, and it evaded the attack in a way of switching laws that he had never seen before.

He withdrew his hand, and the Tai Chi diagram in his dark golden pupils began to rotate slowly at an accelerated speed. His divine sense penetrated the transparent shell of the world's ruins and probed into its interior.

Just then, a voice came from deep within the world's ruins.

The voice was extremely weak, each syllable sounding as if squeezed out with the last ounce of strength, its timbre aged and weary, like someone who hadn't spoken in a long time relearning how to speak.

"Lord of the Underworld...please...stop..."

Yunyi's finger stopped in mid-air.

Then it suddenly accelerated.

"You think you can just stop whenever you want? Don't I have any dignity?"

The man, whose name was "Destiny," paused noticeably in his speech.

Before they could react, an even more violent slap landed.

The giant hand crushed down.

The voice of destiny never rang out again, whether it had exhausted all its energy or had resigned itself to fate.

The world's remains crumbled layer by layer from the outside in—the outer world wall turned into countless fine bronze fragments that scattered everywhere, the withered network of laws in the middle layer was washed away by the Yin energy into the most basic law particles, and the completely still spacetime at the core began to flow and operate again under the erosion of the Netherworld Laws, before being completely torn apart.

Finally, what exploded was a mass of darkness.

The black mass surged forth from the center of the wreckage and expanded rapidly in the void.

With each expansion, countless overlapping roars emanated from within, each roar containing a law-based impact powerful enough to instantly shatter ordinary Yin ghosts.

The pitch black began to condense and take shape.

It was an extremely enormous demonic shadow, hundreds of thousands of feet tall, composed entirely of constantly surging, pitch-black demonic energy.

Its outline is similar to that of a human, but the details are completely different—there are no facial features on its head, only countless tightly closed eyes, stretching from its forehead to its chin, with each eyelid trembling slightly, as if they are collectively trapped in a nightmare.

Twelve pairs of jet-black wings unfolded behind it. The wings had no feathers, only a thin layer of jet-black mucus covering the skeleton, and each joint had a barb growing from it.

His arms were extremely long, hanging down past his knees. Each hand had seven fingers, and from each fingertip extended a thin, dark chain, the ends of which disappeared into the void, their destination unknown.

Immortal evil.

It awoke from a slumber that had been sealed away for countless eons, and the first thing it did was burst into laughter.

Laughter exploded in the void, causing the Netherworld Domain that Yun Yi had set up around him to tremble slightly, and the Yin Ghosts unconsciously took several steps back.

The laughter was mixed with countless different sounds—sharp hissing, deep roaring, hysterical laughter, sinister chuckles—all blending together to form a jarring noise that was unsettling from the depths of the soul.

"Hahahaha—it's out! It's finally out!"

The undead demon threw its head back and laughed wildly, its countless tightly closed eyes trembling violently as if collectively experiencing an intensely exhilarating nightmare. "I am the true master of this world! I destroyed the world! I exposed the coordinates! I orchestrated the entire scheme—all to use outsiders to destroy that seal! To allow myself to transcend! To make myself an immortal and indestructible true god!"

The laughter echoed in the void for a long time before gradually fading away.

Then it lowered its head, and countless eyes simultaneously turned to Yun Yi, who was standing in the center of the Netherworld.

Those eyes were not open, but Yun Yi could feel countless gazes peering out from the gaps in his eyelids, scrutinizing him closely.

The undead demon was silent for a couple of breaths, then its voice suddenly became much more serious. The arrogance and madness in its tone subsided somewhat, replaced by a cautious calm tinged with obvious apprehension.

"However, that old thing still tricked me before it died—it used its remaining luck to reinforce the seal, which took me dozens of epochs longer than expected."

It paused for a moment, then continued in that serious tone, "Well, at least we're out."

"You helped me break the seal, and I value gratitude the most. To thank you, I've decided to run away."

As soon as he finished speaking, the twelve pairs of jet-black wings on the back of the Undying Demon unfurled simultaneously, and the enormous demonic shadow fled into the depths of the void at an astonishing speed.

It ran with extreme decisiveness and swiftness, without the slightest hesitation—its previous arrogant and domineering demeanor vanished completely, replaced by an instinctive intuition that was most acute for absolute danger.

Yun Yi stood still, watching the spot where the Undying Demon had disappeared, without giving chase.

His attention was no longer on the undead demon.

The moment he shattered the seal on that world, some kind of change occurred inside his body.

The change was extremely subtle, like a taut string suddenly snapping, breaking silently, yet causing his entire consciousness to tremble slightly.

Now, the change is complete.

A stream of information naturally flooded into my mind.

Double Netherworld Meteor, achieved.

He is the ruler of the underworld, immune to death—death is no longer a possible event for him, but a tool that can be manipulated at will.

He cannot experience death again, and therefore cannot trigger the metamorphosis of the Netherworld through death.

For a long time, he had been puzzled: since he could not die, how could he trigger the remaining Netherworld Meteor?

Now he knows.

The death of the underworld does not mean his actual death.

The first stage of the Netherworld's demise is the death of the physical body—transforming from a living person into a ghost, completing the first metamorphosis.

The double death of the underworld is the death of will—when he no longer cares about the life and death of the living, no longer tries to maintain any sustainable development, and no longer sees himself as the protector of a group of living people;

When he exterminated all living people, destroyed all the vibrant worlds, and completely forgot the old Yunyi who once cared about the word "living people";

When he truly embraced the Netherworld—pure death, pure end, pure nothingness—the Double Netherworld Meteor was achieved.
