Building the Strongest Undead Empire from Scratch

On the northern border of the Skyreach Mountains, nestled within a small town, Alex blended seamlessly into the surroundings, her invisibility skill concealing her presence. This town was the closest settlement to the stronghold of the Angel Holy City.

Werewolves typically preferred the seclusion of forests, making this town a likely strategic outpost built to counter the encroaching Angel race.

Observing the werewolves going about their daily lives, Alex found herself reminiscing about a distant past. All she had to do now was wait for nightfall and then make her way to the Holy City.

With an inside man aiding her infiltration, Alex wondered if the Angel race's methods of detecting extraterrestrial visitors would still be effective against her.

She perched on a rooftop, taking a short nap as she patiently awaited the arrival of darkness.

She had already assessed the werewolves in this town. The strongest among them was only at the Lv1 Emperor level, posing no threat to her concealment.

As night fell, Alex rose and set off towards the Angel race branch.

Moments after her departure, a burly werewolf materialized on the rooftop, gazing intently in the direction she had vanished, its mind seemingly preoccupied with unknown thoughts.

...

The Holy City was impressive in size, but it paled in comparison to the floating Holy City at the heart of the Eldoria continent. The most striking difference was that this city was grounded, its foundations firmly rooted in the earth.

Even under the cloak of night, the city emanated a faint golden glow, radiating an aura of divine sanctity.

The city gates were sealed shut, an invisible barrier seemingly encasing the entire city, rendering its interior impenetrable to prying eyes.

Unable to see the angels within, Alex relied on her invisibility to approach the city's edge.

She suspected that the golden film enveloping the city wasn't a shield but an alarm system. The slightest touch would likely trigger an immediate response from the angels within.

Instead of rushing in, Alex took out a piece of paper, inscribed a coded message on it with magic, and set it ablaze.

Moments later, a figure emerged from a side gate, approaching the city's outskirts. Alex spotted him and walked towards him.

The man showed no surprise at her sudden appearance, bowing respectfully.

"At your service, Leader. I await Wind's instructions."

"You can get me inside the city?"

Alex looked at him questioningly. The man was dressed in white robes, his head bowed like a devout believer.

"Leader, take this. It will shield you from the Holy City's radiance, allowing you to enter undetected."

Alex accepted the badge-like object, its holy light aura repulsive to her senses.

The inside man led her towards the city. As expected, the golden energy parted before them, creating a human-sized tunnel.

"Leader, I can only take you this far. Without this badge, I would be detected if I went any further."

The inside man stopped at the edge of the barrier. Alex nodded, watching him disappear.

Once inside the city, Alex suppressed her aura and reactivated her invisibility.

The city's interior was a stark contrast to its exterior. The buildings were densely packed, the streets narrow, crowded, and filthy.

The outer city was shrouded in darkness, the only light emanating from the towering palace in the center, radiating a holy glow.

Garbage littered the streets, alleys, and corners. Alex sensed countless life forms within the cramped buildings.

Many civilians lived within the Holy City, but Alex sensed no holy light within them. They were essentially no different from humans.

The living conditions of human and Angel race civilians were worlds apart.

"So this is the Angel race? Not as impressive as I imagined." Alex murmured, making her way towards the grand palace in the city center.

Her first objective was to destroy the Sacred Pool that facilitated the teleportation of angels. Then, she would deal with the Sovereign level angel within the city.

As she ventured deeper, the city's appearance changed dramatically. The streets became wider, the ground spotless.

Even the walls seemed to radiate a faint holy light aura, a stark contrast to the outer city.

The grand palace in the center was circular, surrounded by towering structures. The Sacred Pool lay within the inner circle, enclosed by these buildings.

It was this pool that powered the entire Holy City, giving it its holy aura.

Alex didn't know where the Sovereign level angel was, nor did she dare to approach recklessly. Although she was powerful, her actual level was still Emperor level. Even with invisibility, there was a risk of being detected if she entered the angel's perception range.

She decided to wait for Wind's signal, hiding a short distance from the palace.

With her darkness sphere, destroying the Sacred Pool would be child's play.

Time seemed to crawl by. Alex guessed that several hours had passed, but she couldn't be sure. She could only wait for the orb in her hand to glow, signaling the start of the operation.

Suddenly, she felt a warmth in her hand. She looked down and saw the orb emitting a faint yellow light!

Before she could react, the palace before her erupted in a blinding golden light. A thick beam of light shot up from the Sacred Pool, piercing the sky.

The entire palace lit up, and countless angels poured out, preparing to enter the beam of light.

Alex was surprised by the Angel race's swift reaction. It seemed there was some kind of connection between the Sacred Pools.

It was time to act. Alex teleported to the center of the palace complex, appearing at the edge of the Sacred Pool.

She unleashed a wave of black energy, like ink dripping into the pool.

Instantly, the entire pool was tainted, its golden light extinguished.

The angels, who had leaped into the beam of light, fell through empty space, staring at the Sacred Pool in confusion.

A beautiful woman stood at the edge of the pool, smiling at them!

The angels charged towards Alex, and a terrifying power erupted from the city, shaking its very foundations. Buildings in the outer city collapsed.

The Sovereign level angel had arrived!

"Are you courting death?"

Angel's voice, usually devoid of emotion, was laced with rage.

Alex remained calm. A massive gray magic circle materialized behind her.

A colossal Death Dragon emerged from the circle, its aura equally formidable!

But that wasn't all. Several Emperor level beings followed the Death Dragon.

"Undead!"

The surrounding angels gasped. Even the Sovereign level angel was puzzled by the undead's presence.

But his ingrained hatred for the undead left him no time for contemplation. He rallied all the angels in the city, ordering them to attack!

Alex smirked, rising into the air.

"Kill every enemy in sight!"
