Immortality: Starting with a grave, I'm invincible when burying corpses.

As the nine true demons held a meeting, their demonic blood boiling and they wished they could devour several worlds on the spot, a colorful portal quietly appeared above the Nine Nether Demon Abyss.

The first level of the Demon Abyss, the Blooming Spirit Demon Realm.

Mu An and the Old Celestial Master stepped out of the spatial passage one after the other, their gazes falling upon the demonic land below.

More than three hundred years have passed, and the once peaceful and stable Zhanling Realm, with its brilliant cultivation civilization, has disappeared.

Instead, a scorched earth covered by boundless demonic energy was created.

A black sun hangs in the sky, beneath which stretches an endless, mottled earth.

Towering, jet-black mountains undulate across the land, like terrifying beasts crawling upon the demonic soil.

Each of their breaths causes the demonic energy to surge, unleashing a terrifying storm on the scorched earth.

The spiritual veins between heaven and earth have disappeared, and one after another, the immortal mountains have turned into demonic caves. All the human cities within sight are covered by black miasma, and strange plants resembling moss are thriving in the black miasma.

The vast majority of buildings have disappeared, swallowed up by the black miasma over the long years, turning into resources for the birth of demons.

Only a very few buildings constructed with special spiritual materials still retain some ruins, allowing people to imagine their former glory through these relics.

However, with a little observation, it is not difficult to find that these remaining relics are becoming more and more dilapidated every moment, and may fall into the black miasma below at any time.

If you look closely, you can see several broken and damaged magical artifacts.

Most of these magical artifacts are hidden deep within the ruins, and it is their existence that has allowed these ruins to survive to this day.

However, judging from the dim spiritual light and surface cracks of the magical artifacts, it is likely that in a few decades at most, these magical artifacts will completely lose their effectiveness and sink into the abyss below along with the ruins.

……

Stepping out of the colorful portal shrouded in dark clouds, Mu An's gaze swept across the world below.

In less than two breaths, Mu An seemed to have discovered something. Suddenly, he took a step forward and his figure appeared above a broken mountain peak.

Half of the mountain peak had fallen into the black miasma, swallowed by the extremely dense demonic energy, while the other half remained standing, diagonally embedded in the earth.

A hurricane composed of malevolent energy howled past, constantly eroding the remaining mountainside.

Under the puzzled gaze of the old celestial master, Mu An walked all the way to the highest point of this half-mountain peak.

There stands a dilapidated palace crafted from sunset clouds and white jade. Despite its ruins, the palace retains its original form and has not been corrupted by the black miasma.

At first glance, the old Celestial Master did not notice anything special about the palace, assuming it was the former site of a sect in a sacred place in the Spirit Realm.

He had also spent some time in the Spirit Blossom Realm and had some understanding of it.

The Blooming Spirit Realm has a long history and profound heritage, and has developed the immortal civilization to an extremely high level.

Although their number of strong individuals is not large, they have made significant achievements in formations, puppets, and mechanisms.

It's not surprising that their sacred sect grounds, built without any specific targeting from the Demon Abyss, could withstand hundreds of years of erosion.

It's not surprising that there are one or two palaces that are relatively well-preserved.

That being said, what could possibly catch Mu An's attention must not be any ordinary place.

Filled with curiosity, the old celestial master fully unleashed his divine sense, carefully observing the entire palace from top to bottom.

After checking it carefully again, he finally discovered the problem.

"This is... the Five Elements Spiritual Light?"

A faint layer of five-elemental spiritual light surrounded the surface of the palace, not in the form of an array or a protective shield, but rather seeped into the surface of the building.

It is precisely this faint spiritual light of the five elements that has allowed the palace below to withstand the erosion of the demonic abyss until today.

With a hint of confusion, the old master stepped forward and came to stand behind Mu An.

Following Mu An's gaze, a broken plaque came into the Old Celestial Master's view.

"Today's Illusion Palace"

"This is..." the old master murmured. He remembered clearly that when Mu An visited the Blooming Spirit Realm, his first stop was the Illusion Palace.

Could the five elements of spiritual light here be a work left by Mu An back then?

But if that's really the case, why haven't I returned here all these years?

For Mu An, who had long since become a Golden Immortal, the Nine Netherworld Abyss posed no threat whatsoever; he could come and go as he pleased.

If you're in a bad mood, catching a few real demons to make soup or barbecue is no problem.

If Mu An had really had designs on the Nine Nether Demon Abyss back then, the Nine Nether Demon Abyss would probably have disappeared long ago, and wouldn't have survived until now.

Though he harbored doubts, the old master did not show them.

He followed Mu An, step by step, into the depths of the palace.

As they walked along the road, Mu An's voice suddenly rang out.

"More than three hundred years ago, I visited the Spirit Blossom Realm with Fellow Daoist Li. In order to maximize our benefits, we chose to split up. The Illusionary Palace we are in now was my first stop back then."

"The moment I saw the Illusionary Palace, this thought came to me."

"This place is more like a cultivation world than our Nine Domains. Even Fellow Daoist Li's Four Symbols Mountain doesn't have this atmosphere."

"But fellow Daoist, look now. All you see is black earth. Apart from the evil energy, there is nothing else in the world. All traces of human civilization have been completely erased..."

"In just over three hundred years, this once-glorious sect has become what it is today..."

Perhaps because the main body of the Illusionary Palace had long since sunk into the black miasma and the abyss of demons, the remaining palace was not very large. In just a few words, the two had already covered most of the distance and arrived at the center of the palace.

The old master listened quietly without uttering a word.

He knew perfectly well that Mu An was not talking about these things, after all, when they came to the Spirit Blossom Realm, Mu An was on the verge of Dao transformation.

From an outsider's perspective, Mu An back then was even less humane than he is today. His mind was devoid of anything but his obsessions, and he would never have been interested in these things.

No matter how wonderful the Spirit Realm was, it couldn't possibly move Mu An at that time.

As for Mu An now, even the Old Celestial Master dared not make a definitive statement.

Over the years, Mu An has become increasingly incomprehensible to him, both because of the difference in their cultivation levels and because of the changes in Mu An's attitude and personality.

The old celestial master couldn't understand at all what state Mu An was in now.

But no matter what, everything in the Spirit Blossom Realm is in the past. There must be other reasons for bringing it up now.

Just as the old master had predicted, Mu An's calm narration did not stop. After a simple remark, the topic suddenly changed.

"The mountain we are standing on is called Jin Huan Peak. It has eighteen levels. And this palace, which is made of sunset and white jade, was the residence of the palace master of Jin Huan Palace at that time."
