Hello, is this a letter addressed to Demon Fortress?

Bill walked out of the temple.

The moonlight slanted across the ruins, casting his shadow as a thin, dark streak.

The death scouts are already waiting outside the door.

It was the shriveled corpse of a scout, with sunken cheeks and two clusters of eerie green light flickering in his eye sockets, like cold phosphorus buried in ashes.

Bill glanced at it.

"lead the way."

The scout turned and silently drifted into the depths of the ruins.

Bill followed behind, walking at a leisurely pace.

The hem of the dress brushed against the pebbles without stirring up a speck of dust.

The city of Mirror Shadows was as silent as a tomb in the night.

The wind howled as it passed through the broken windowpane.

Bill thought of Bounty City.

That day, he and Jesse brushed past the black-haired mage.

Jesse, unusually, after that person left...

There was a long silence.

"Be careful of this person."

She spoke calmly, but unusually used the word "be careful."

"His concealment magic..."

She paused.

Even my father couldn't see through it.

Bill raised an eyebrow.

Jesse's father, Carl.

That man whom even the vampire elders were wary of.

Even he couldn't see through it?

A high-level mage's stealth spell?

At the time, Bill just found it absurd, and even wanted to laugh.

At this moment, he walked through this desolate ruin.

That thought resurfaced.

The opponent possesses stealth techniques that even legendary assassins cannot detect.

But he deliberately allowed the Death Knight, whose senses permeated the entire Mirror City, to discover his whereabouts?

He paused for a moment.

This is too deliberate.

Like a hunter deliberately revealing his scent to lure a wild beast into a trap.

Bill frowned slightly.

But Jesse made it clear that the other party was not a chosen one of God.

There is no divine power.

So, how did he do it?

High-level magic, spanning two levels, achieving a legendary level of stealth effect.

As a mage, Bill knew all too well what this meant.

impossible.

Totally impossible.

He had read extensively from the vampire clan's millennia-old collection of books and consulted countless lost ancient texts, yet he had never heard of any high-level magic capable of achieving such a feat.

Therefore, there is only one answer.

Jesse and Carl, you've got it wrong.

That mage was probably just there when they sensed him...

A legendary stealth scroll has been activated.

The more Bill thought about it, the more reasonable it seemed.

He didn't believe that such magic existed in the world.

It was created by a high-ranking mage.

His steps became light again.

A smug smile curled at the corner of his lips.

"Modo."

He casually asked the scout beside him.

"Where is that mage now?"

Each Death Knight has established a connection with Mordo, through which he can communicate with Mordo several kilometers away.

The scouts stopped.

silence.

The withered body remained frozen in place, like a puppet whose signal had been interrupted.

A few seconds later, it turned its head.

The eerie fire in his eyes flickered for a rare moment.

The movement carried a strange sluggishness.

"...disappeared."

Bill was taken aback.

"Disappeared?"

He thought he had misheard.

The scout's tone remained dry and flat:

"Yes, it's gone."

"I sent assassins and mages to keep an eye on their location."

"And then—"

It paused.

"It just disappeared."

"An assassin's secret detection techniques, a mage's sensory magic..."

"We couldn't detect their presence."

Bill's smile froze on his face.

disappear?

He opened his mouth, but for a moment he didn't know what to say.

From the edge of the nearest Wailing Wall to Mirror City.

There were no supply points along the way; they were all dead cities.

Even for them, it would take at least four days.

The longest a legendary scroll can last is no more than one day.

This is an unwritten rule in the magical world.

If the other party really did use a scroll to hide.

It should have been obsolete long ago.

Bill was silent for a few seconds.

The arrogance on his face finally faded somewhat.

He frowned, his voice low:

"Have they lost any hair or anything like that?"

The scout shook his head.

"No. In the places they stayed..."

It paused.

"No skin flakes, hair, or bloodstains were found."

Bill's eyes darkened slightly.

The tracking of Modo's soul requires a medium.

Blood has the best effect, but it only lasts for a few hours.

The hair effect is poor, but it can last for several days or even longer.

But the prerequisite is that you must have hair.

Bill took a deep breath.

The voice turned cold.

"If the other side truly possesses a concealment magic that we cannot see through."

He paused.

"And then there's that priest replenishing his magic power from behind..."

"He can remain hidden indefinitely."

His tone was calm, yet it subtly suppressed some emotion he had never felt before.

"...so that we'll never find it."

The scout did not answer.

It just stood there quietly, like a real corpse.

Bill suddenly raised his hand.

A blood whip swept out!

boom--!

Half of the remaining wall beside him collapsed with a crash.

Pebbles flew everywhere, and dust filled the air.

The moonlight was churned into a murky white.

His chest heaved violently.

original.

He planned to easily catch the mage and bring him to Jesse.

Look at the surprise that will show on her usually calm face.

"Look, this is the person you wanted me to pay attention to."

"I caught it like a chick and brought it back."

How interesting.

How delightful!

But now?

He couldn't even find the other person, let alone catch them.

Bill unleashed another bloody blade.

The wrought iron sign on the street was cut in two and fell to the ground with a thud.

In the smoke and dust, his face was terribly gloomy.

The scout stood silently to the side, watching Bill's outburst.

Bill was panting heavily.

His gaze swept aimlessly across the ruins.

then.

He saw it.

A beam of moonlight slanted across the street corner.

There was a coffee shop that had mostly collapsed.

On the broken door frame, at some unknown time.

A wooden board was nailed to it.

On the wooden board, a line of words was written crookedly with charcoal pencil.

The handwriting is neat and even has a touch of deliberate playfulness.

Bill squinted at the words above and slowly read them aloud:

"What you're looking for—"

He paused.

"Being warned by Jesse's companion—"

He paused again.

"The concealment magic is powerful—"

His voice grew slower and slower.

The last few characters were larger, drawn with heavy charcoal, until the edges of the paper were worn rough.

"Handsome, invincible, and incredibly kind—"

"The Mage Messenger—"

"Over there."

below.

It has a big arrow drawn on it.

The arrow is pointing northeast.

The direction of the silent crack.

Bill stared at the plank.

long time.

Not moving at all.

Bill's expression under the moonlight...

It's hard to describe.

"..."

He opened his mouth.

No sound was made.

He opened his mouth again.

Finally, a strange syllable was squeezed out of his throat:

"……ha?"

The night wind swept through the ruins.

The wooden board swayed slightly.

The charcoal writing was so clear it was almost blinding in the moonlight.

The arrow was even drawn twice.

I was afraid he would look in the wrong direction.

But in a corner that Bill couldn't see.

A densely packed array of glass beads were squeezed into the gaps between a pile of miscellaneous items.

A faint blue light flowed within the bead's surface, like swarms of plankton in the deep sea.

They huddled together, their soul lights flashing rapidly.

It's like exchanging some kind of silent language.

After confirming that they had not been detected, they began to move.

One.

Two.

Five.

Ten.

They rolled along the base of the wall, hiding in the shadows of the broken tiles, and passing through the half-collapsed door frame.

One by one, they arrived at the corner at the edge of the coffee shop.

It flashed at another shimmering bead in the ruins not far away.

After the other party responded, they quietly rolled into the deeper shadows.

And near each Death Knight in Mirror City.

Street corners, rooftops, behind broken walls, and even piles of rubble three zhang behind the knight.

There are a few inconspicuous glass beads in each one.

They lay there quietly, their soul light dimmed to its lowest point.

They watched the knights' every move.

The Death Knights of Mordor watch over the entire city-state.

They control this transit city, a necessary passage to the Silent Abyss.

Every intersection, every street, every possible hiding place.

There are silent dead people patrolling and sensing.

They thought they were the sole masters of this dead city.

But don't know.

In this seemingly lifeless city-state.

There is also a group of "people" who are everywhere.

They were spying on them.
