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

Over the course of a thousand years, Yun Yi transformed this Netherworld Kingdom from a chaotic post-war ruin into a sophisticated Netherworld machine.

With the world remnant that he had shattered and then reassembled by the laws of the underworld as its core, the underworld kingdom spread out in all directions, transforming into nine layers of underworld dimensions.

The outermost three layers are the dwelling places of ordinary ghosts. Trillions of grayish-white spirits live and multiply here, retaining all their memories and emotions from their previous lives. Apart from being semi-transparent and not needing to eat or sleep, they are almost indistinguishable from when they were alive.

The middle three layers are the domains of the Soul Reaper and the Spirit.

The soul transforms into a spirit through repeated death trials, while the spirit, nourished by the laws of the underworld, strives to reach a higher level of the Soul-Binding rank.

The innermost two layers are the territories of Yi Po and evil god-level Yin ghosts.

Seventeen evil gods and ghosts each occupy an independent space, constantly evolving their power under the blessing of the laws of the underworld.

The ninth dimension is Yun Yi's residence—the Netherworld Temple.

The temple floats in the center of the ninth dimension, its shape is exactly the same as the original Netherworld Temple in Netherworld City, but its scale is many times larger.

The temple was formed from pure Netherworld laws, and its surface was covered with countless fine, dark runes.

Yun Yi stood at the highest point of the temple, with the surging sea of ​​dark mist beneath his feet and the yin-yang sky above him, a tapestry of ghostly green flames and golden holy fire.

A thousand years have passed, but his appearance has not changed at all. He still has the outline of a young man and is still wearing that black robe that constantly emits gray-white mist.

Over the course of a thousand years, he used the "self-evolution of the laws of the underworld" ability granted by the double underworld meteorite to cultivate the underworld kingdom from a simple realm into a complete ecosystem.

New branches of laws have evolved spontaneously within the Netherworld, some of which he did not even design, but rather naturally generated from the collective unconsciousness of billions of Yin ghosts.

For example, the "River Styx" is a gray-white river that runs through nine dimensions. Its water is made of pure liquid yin energy. Any ghost that soaks in it can accelerate its own transformation.

For example, "Netherworld Crystal Ore" is a crystallization of Yin energy that settles at the bottom of the River Styx. It contains highly compressed fragments of laws and can be used to forge Netherworld artifacts.

For example, the "Ghost Fire Forest"—a ghostly green flame plant that grows spontaneously in a large area of ​​the fifth dimension.

They have no physical form, consisting entirely of will-o'-the-wisps, and their shape and color change depending on the concentration of yin energy.

The number of ghosts in the underworld is beyond calculation.

A century after the completion of the Double Netherworld Meteor, one of the branches of the law, the "Law of Yin Ghost Proliferation," naturally evolved: two Yin Ghosts can register in the Netherworld Temple and merge their Yin energy origins to give birth to a brand new Yin Ghost individual in the River Styx.

The newborn ghost has no memories of its past life and grew up entirely in the Netherworld. Its loyalty to Yun Yi is deeply ingrained in the very core of its soul.

They are the true "original species of the underworld".

Yun Yi's strength, through the continuous accumulation of Yin energy and the evolution of laws over a thousand years, has risen to a level that even he himself cannot accurately measure.

But just how strong he is, he himself doesn't know.

Because there is nothing left in this void that warrants his full effort.

In the past thousand years, he has not found any other worlds.

The notification sound for the Paradise of Reincarnation never sounded.

He even wondered at one point whether he had been forgotten by the cycle of reincarnation.

At this moment, his dark silver pupils calmly swept across the nine dimensions beneath his feet.

His divine sense instantly covered the entire Netherworld, penetrating every level of dimension, every ghostly spirit, and the operational trajectory of every branch of law.

Everything was perfect.

so perfect.

It was so perfect that he felt something was off.

It was this "perfection" that made Yun Yi's divine sense pause for a moment.

The rapidly spinning Tai Chi symbol deep within the pupil suddenly slowed down and stopped at an extremely precise angle.

The entire Netherworld Kingdom came to a standstill—all sounds in the nine dimensions vanished simultaneously, the surface of the River Styx solidified into a gray-white mirror, the flames of the Ghost Fire Forest all stopped, and the seventeen evil gods and ghosts simultaneously looked up towards the direction of the temple.

After a moment, everything returned to normal.

The River Styx continued to flow, the Will-o'-the-Wisps Forest continued to burn, and the little ghosts continued to frolic and play on the riverbank.

Yun Yi withdrew his divine sense, raised his right hand, and slightly spread his five fingers.

Mu Baiwei and Shen Ye, who were in seclusion cultivating behind him, were summoned to the Netherworld Temple at the same time.

Mu Baiwei still looked like a little girl in a black dress; a thousand years had left no trace on her.

Her Yi Po form has made another breakthrough in the past thousand years. Although she is still quite far from the next form, she is already the closest one in the Netherworld.

Shen Ye's changes became even more obvious.

He has died countless times over the millennia, and each death has been a transformation.

His Yin Ghost rank has reached the Yi Po level, second only to Mu Baiwei.

This is naturally inseparable from his tireless hard work and dedication over the years.

The shadow of that golden-haired saint from back then has completely disappeared from him, replaced by a calm and abyssal aura of the underworld.

"You two, use the Return Crystal."

Yun Yi's voice was completely flat, "Return to the Paradise of Reincarnation immediately."

Mu Baiwei was stunned, and Shen Ye was also stunned.

"Now?" Mu Baiwei tilted her head. "My lord, once the Return Crystal is used, there's no going back. Are you sure?"

The two exchanged a glance and said nothing more.

For them, Yun Yi's orders were absolutely not to be questioned.

Mu Baiwei was the first to take out the Return Crystal.

It was a transparent crystal the size of a fist.

As energy was injected, the patterns glowed with a soft white light, enveloping her figure.

A moment later, she disappeared along with the crystal.

Shen Ye followed closely behind.

However, after a short while, nothing changed around him.

He looked up at Yun Yi:

"Sorry, I can't use it."

Yun Yi nodded, confirming one thing at the same time: his Yin Ghost was indeed still considered a "surviving reincarnator" by the Paradise of Reincarnation.

The fact that Shen Ye cannot use the return crystal also proves that the number of surviving reincarnators in this world still exceeds the return limit.

As Yun Yi was thinking, he suddenly grabbed something.

A sinister-looking man was instantly captured by him.

Before the other party could react, thinking they had been ambushed, they were about to open their mouths when they looked up and saw Yun Yi. They immediately put on a fawning expression.

But before he could even speak, his consciousness was sealed by Yun Yi.

Yun Yi then granted Shen Ye the ability to devour Yin ghosts, and threw the man in front of Shen Ye:

"Use the power I just gave you to devour him."

Shen Ye was taken aback, and a hint of excitement even flashed in his eyes.

But obedience to Yun Yi had become instinctive, so he immediately took action and devoured the man.

After doing all this, Shen Ye himself found it hard to believe—he had actually killed a person with authority.

"Now that we've finished swallowing it, let's use the Return Crystal again."

Upon hearing this, Shen Ye first knelt on the ground and kowtowed heavily to express his gratitude to Yun Yi for his great kindness. Then, without delay, he immediately activated the return crystal.

Yun Yi stood there, and after confirming that Shen Ye had disappeared, he waited for a long time, but the notification sound from the Paradise of Reincarnation still did not sound.

He remained silent for a long time.

One authorized user died, and another authorized user and a reincarnator returned to the fold.

No matter how you calculate it, it shouldn't still exceed the upper limit.

Surely... all the remaining reincarnators are still alive?

Yun Yi remained silent until finally letting out a soft sigh.

That's it.

In the Netherworld, there are no longer any samples that need to be preserved.

It's time for him to start his own plans.

He closed his eyes.

Although his dark silver pupils were covered by his eyelids, the light from the Tai Chi diagram deep within them shone through, casting the entire Netherworld Temple in a chaotic, flickering light.

Then he spoke.

The sound resounded in every corner of the nine dimensions, piercing the River Styx, the Forest of Ghost Fire, every Netherworld City, and the core of every Yin Ghost's spirit, like a brand etched deep into the soul:

"All citizens of the underworld, return to your places."
