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

Two magical artifacts, one for offense and one for defense.

The Banner of Ten Thousand Demons Annihilation is an unparalleled demon banner conceived by the Crimson Fire Demon Lord and forged by the joint efforts of twenty-one demon lords.

It took the twenty-one demon lords of the Yin Yin Domain over a hundred years to forge this sacred demonic artifact.

Nine of the demon lords lost their lives for various reasons during the forging of the demon banner, and the subsequent demon lords took over the forging process.

Over a century, through the succession of two generations of demon lords, the flesh and souls of three billion humans, the corpses of seven billion intelligent sea creatures, and countless other intelligent beings, all came together to form the raw materials for the Banner of Ten Thousand Demons' Annihilation.

During its forging, the Banner of Ten Thousand Demons Annihilation incorporated the Great Dao of fifteen Demon Lords, making its power even more exaggerated than the Demon Lords had initially envisioned.

This is the most powerful demonic artifact in the history of the Nine Realms, a supreme weapon capable of directly clashing with Liu Yun, and the culmination of the Yin Yin Domain Demon Lord's work.

Even after searching through the entire history of the Nine Realms, the Demonic Path has never produced such a treasure.

The Purgatory Spirit-Slaying Umbrella is a supreme defensive treasure of the demonic path. Although it is slightly inferior to the Myriad Demons Annihilation Banner in terms of killing power, it has one of the best defensive capabilities in the world.

This umbrella was designed by the White Bone Demon Lord, and a total of seventeen demon lords participated in its creation before finally forging this peerless demon umbrella.

In the initial design phase, the demon lords actually wanted to create a peerless demonic artifact that could isolate all the energy in the world.

In the White Bone Demon Lord's original plan, the Purgatory Spirit-Slaying Umbrella would have its own independent small world.

An umbrella is a world unto itself.

The small world within the umbrella exists within the Nine Realms, yet it possesses laws of heaven and earth completely different from those of the Nine Realms.

Once an enemy falls into the world within the Purgatory Spirit-Severing Umbrella, they will be severed from their connection with the Nine Realms and unable to mobilize even a trace of spiritual power.

Even a terrestrial immortal who falls into it will have his strength greatly reduced because his connection with the Great Dao of Heaven and Earth is severed, and he will eventually die and his soul will be destroyed.

It must be said that the White Bone Demon Lord's idea was very beautiful, but in the actual forging process, a series of intractable problems arose.

Even if all the demon lords of the Yin Yin Domain used their best abilities, they still couldn't create such a small world.

The will of heaven and earth in the Nine Realms does not allow such a small world to be born.

Ultimately, the demon lords had no choice but to settle for second best. First, they reduced the size of the small world by several times, and then they abandoned the idea of ​​creating different laws of heaven and earth, instead simulating the laws of the Nine Realms to create the small world.

After nearly a century of effort, the Demon Lord of the Yin Yin Domain used tens of thousands of islands and slaughtered hundreds of billions of living beings to combine nature and spirituality, finally creating a small world connected to the Nine Domains within the Purgatory Spirit Umbrella.

This mysterious little world is regarded by countless cultists as a sacred place of the demonic path, the highest hall for all those who follow the demonic path.

However, this small world has another name according to the twelve demon lords who rule this realm.

The Yin Yin Domain, a sacred place of demonic cultivation—the Purgatory Realm.

The umbrella has two sides, one red and one black. Red represents fire and black represents demons. When the two are combined, they can unleash their full power and drag the enemy into purgatory.

Those who enter this realm will be scorched by tens of thousands of flames; the name "Purgatory" is truly fitting.

Moreover, although the Purgatory Spirit-Severing Umbrella cannot isolate the laws within the Nine Realms, it can sever spiritual energy and primordial energy, rendering most supernatural powers and spells ineffective.

Whether it's Taoist magic, Buddhist supernatural powers, or the righteous spirit of literature and righteousness, they will all lose their effect in the face of this umbrella.

It is precisely this unique effect that makes the Purgatory Spirit-Slaying Umbrella the strongest demonic defensive treasure in the world.

……

It's ironic that the reason why these demon lords, who are usually "as close as brothers," were able to unite so closely, setting aside all their grudges, and work together to create these two peerless demonic treasures is that...

If we really want to get to the bottom of it, the reason is still the calamity of the falling star back then.

On that day, Mu An's great divine power of shattering stars and opening up a new realm terrified all the terrestrial immortals in the world, and even more so the demon lords of the Yin Yin Domain.

In order to deal with the potential "life-or-death threat", the Demon Lord of the Yin Yin Domain united as never before and jointly promoted the forging of two magical artifacts.

I don't ask to fight against Mu'an, I only ask to have a means of escape when disaster strikes.

If that were all, these two demonic artifacts might not have been able to be created smoothly, since they were extremely expensive to produce and their creation was more difficult than ever before.

As for beings like demon lords, they have always been synonymous with betrayal, and intrigue and backstabbing are commonplace for them.

However, not long after the birth of the Starfall Domain, Mu Ling'er took Mu An on a journey around the world.

During his journey, because of Mu Ling'er, Mu An killed five Demon Lords with a flick of his wrist, which scared the remaining Demon Lords away for millions of miles, forcing them to flee the Yin Yin Domain.

After that, the surviving Demon Lord never mentioned any difficulties again, focusing all his attention on the two sacred demonic artifacts, and finally managed to complete these two magical treasures within a hundred years.

Mu Ling'er was unaware of all these things.

The overwhelming resentment and vengeful spirits drew Mu Ling'er's full attention; she had never seen such a massive amount of resentment and vengeful spirits before.

Twisted, painful, angry, cold, desperate...

From Mu Ling'er's perspective, countless negative emotions intertwined, forming a giant net that covered the sky and enveloped the world.

Countless wraiths howled and roared beneath the giant net, uttering piercing wails.

Thick, viscous black blood rained down from the heavens, turning the black soil into a purgatory as it landed. Demonic flames soared into the sky, and endless souls of the dead lingered on the earth.

In the blink of an eye, all life within a radius of a hundred miles vanished completely, replaced by an endless purgatory.

The grass and ancient trees on the ground turned to scorched ash, the birds and beasts were devoured of their life essence and turned into white bones, and even the rushing river turned into black water that devoured all life in an instant.

Seeing this scene made Mu Ling'er's face grow increasingly pale.

She had imagined countless terrible things, and she had thought about the unimaginable suffering that the beings in the Yin Yin Domain must have endured, but she never imagined that these despicable beasts would do such a terrible thing.

The Demon Lord of the Yin Yin Domain always manages to push the boundaries of her understanding time and time again.

Inhale, exhale.

The wailing, so loud it defied description, echoed in Mu Ling'er's ears, constantly stimulating her beating heart.

The moment she raised her head again, Mu Ling'er's eyes turned completely blood red.

"I was so stupid..."

"I can't believe I'm getting so hung up on the life and death of these beasts..."

"That's right... The more I hesitate and struggle, the more unrestrained these beasts will become, doing one unimaginable thing after another when I can't see them..."

As she murmured to herself, Mu Ling'er's expression gradually hardened, and she gave instructions to Qing Xi, Mu Yong, and the others who had rushed over.

"Issue my order: effective immediately, the Great Spirit Empire declares war on the demonic forces of the Yin-Yang Domain. The war will not cease until the demonic forces are eradicated!"
