Who Designed This Underworld Dungeon?

Yanor Kingdom, Royal City.

Today is a star-studded day.

For ordinary folks, a star-studded night is considered a rare beauty; for astrologers, it's a sight worth observing; for certain sects, it's considered a divine phenomenon.

But for Ainz III, every star-studded night is...

"Is everything ready?"

Standing at the highest point of the Royal Palace, he faced the night sky with hands behind his back. The chilly evening breeze tousled his hair, turning healthier and browner. He waved off the attendant who tried to drape a cloak over him, asking without looking back.

"Ready, Your Majesty. This time we've gathered dozens of archaeologists and used the oldest known historical language." The attendant replied, handing over a magic tool with a handle-shaped end and a button on top, unsure of its purpose.

"Very good!"

Ainz III revealed a strong sense of anticipation, grabbed the magic tool, and at that moment felt a turbulent sensation in his blood, his body hair twitching as if trying to grow wildly like a beast's fur, but it was suppressed by another unknown force within.

The distant stars glittered brilliantly, as if something was lurking beneath them, watching this place.

"As expected, whenever the stars shine brightly, that son-of-a-dog Evil God starts bothering me again."

Ainz III's words were quite crude, his smile stretching wide.

The attendants beside him broke into a cold sweat hearing his unkingly coarse speech. General Gulimanpo signaled the magicians maintaining the Spiritual Defense Magic Array, and the magic array covering the entire palace instantly intensified, ensnaring the palace within a sapphire-blue "egg shell."

Ainz III then boldly pulled out a... Blood Collection Bottle?

He boldly stabbed two Blood Collection Bottles, sighed long and comfortably, his eyes turned dazed; this item was far more potent than the Blood Healing Potion the Bed Family was about to discontinue.

As the Blood Collection Bottles infused into his body, the beastification tendencies were instantly suppressed. At this moment, he felt the culprit behind his beastification—the Evil God Hidden Dull Star's anger, and without hesitation, he pressed the button on the magic tool!

It lit up! The whole city lit up!

One after another, massive beams of light shot skyward from the gigantic magic array, resembling rockets soaring into the sky, over a hundred of them, supported by the immense magical power of the magicians, flying higher and higher towards the purple gleam in the starlight, seeming to be aimed at the Evil God's face.

And these glimmers intertwine to form ancient words, unused by anyone now; even archaeologists aren't certain of their exact meaning, speculating based on general ideas, and spelling them out according to Ainz III's instructions.

"Daddy, Daddy, what do these words mean?" In Royal City, a child looked at his father with innocent curiosity.

"Well, um, these words are... they are the King's courteous language advising the Evil God to let go of hatred and achieve reconciliation," the father said with a strained smile.

"Oh, oh, I see; the King is really a polite person."

"..."

The father turned away, his expression finally breaking, silently shouting in his heart: King, aren't you afraid of setting a bad example for children with this behavior!

In fact, the residents of Royal City had experienced such events multiple times; this was already the third time. The first time, the language used was the current official language, and the second time, a slightly older one.

The meaning of these scrambled words was simple.

To send regards to the Evil God's entire family.

With quoted regards.

The citizens all knew what Ainz III was up to—he was using profanity to taunt the Evil God, fearing the Evil God wouldn't understand the words, he chose the oldest language!

Their beloved, great King was splendid in every way, except for his habit of holding grudges. Ever since he discovered something in Sain Dungeon, almost completely freeing himself from the Evil God's beastification influence, he started contemplating ways to disgust the Evil God. The current "profanity face-off" was his first move; more sinister tactics might follow.

Some thought Ainz III's actions were inappropriate, appearing too frivolous and petty, but others thought such behavior was incredibly cool. Which other king in the world dares to lead the charge against an active Evil God? None! The King is truly brave and unparalleled!

What, you ask how Ainz III knows his antics truly anger the Evil God instead of just seeing them as a joke?

There's certainly a way to find out.

"Here it comes, here it comes."

When the affectionate greetings flew into the sky, Ainz III immediately felt the beastification suppressed by the Blood Collection Bottles raging intensely, which was the Evil God's response. And facing such a response, what he could do was...

"[Return to Hometown]."

He shook the casting medium in his hand, and his whole body vanished on the spot.

People had grown accustomed to this; General Gulimanpo smoothly directed: "Prepare to welcome His Majesty at Sain Dungeon."

With Sain Dungeon as a backup, Ainz III feared nothing in provoking the Evil God!

As long as he ran into Sain Dungeon, all the Evil God's influences on him would vanish. Though it's unclear why the dungeon can block the Evil God, it is undoubtedly a safe zone!
