Upon arriving before the edifice, Bayou realized it was far more imposing than she had anticipated.

Rather than a single entrance, there are eight doors, each adorned with a peculiar skull from whose eye sockets emanated a descending dark mist.

As Bayu stepped onto the mist, she advanced towards the entrance.

While Chinua felt a sense of comfort, only Chinfong employed light elements to resist the encroaching darkness.

Fortunately, as by you, subordinate, the darkness posed no harm to Chin Fong, though was undeniably discomforting.

As the trio approached the fortress of the undead, the grand entrance swung open automatically, revealing a shroud of darkness behind it, akin to a barrier of energy.

Even with the doors a jar, the three could not discern the scene beyond.

This scene instilled a sense of trepidation in Chinua, as if some lurking monstrosity awaited just beyond the door.

Bayou, undeterred, approached directly and reached out to touch the dark barrier, her hand astonishingly passing through it.

Without hesitation, she stepped forward, vanishing before the eyes of the siblings.

Exchanging a glance, the two followed suit, stepping into the unknown.

Upon entering, Bayou was astounded to discover an entirely different realm within.

This phenomenon, related only partially to the term necromancer's fortress, bore no resemblance to a fortress at all.

It possessed spatial attributes.

Looking upward, she beheld a void of darkness, devoid of any discernable features.

Glancing down, her feet were shrouded in an expanse of black mist.

Before her stood a colossal black portal, so immense that even a zombie titan could traverse it with ease.

The surroundings were encircled by smooth black walls adorned with peculiar patterns.

Each etched design seemingly missing a fragment, losing its inherent grace.

A black six-faced crystal gradually emerged from the mist at her feet, which Bayu picked up for inspection.

It was profoundly dark, identical to the construction material of the main fortress.

Upon activating the supply function, the crystal core was swiftly enveloped in skeletal remains, forming a palmsized sphere, indicating that it was fully charged.

The method of utilization was remarkably straightforward.

One merely needed to click on a construction option and cast it upon the ground.

This item seemed to serve a singular function, as by you found no other remarkable features.

Nevertheless, its teleportation ability alone would prove invaluable.

Boss, do you think our castle will possess something similar when upgraded to a city? Chunu inquired with curiosity.

Em manure.

It's currently unclear whether this is exclusive or universal.

Bayou replied, unable to discern if this teleporting necromancer's fortress was a special reward from the system or a standard benefit of upgrading to a city.

Perhaps other lords would receive their own unique structures like goblin fortresses or demon fortresses upon upgrading.

Let us move on.

There is nothing more here.

With that, Bayou turned toward the exit, prompting the siblings to hastily follow.

The day was drawing to a close, and Bayou intended to construct the first fortress crystal at Aman City to assess its effects.

She planned to refresh another crystal the following day and then prepare to assault the goblin kingdom.

Bayou speculated that the refresh mechanism for this item was akin to that of barracks, occurring every 24 hours, which explained why it would not be available until the same time the next day rather than at midnight.

Chunf, could you please make a trip to construct it in a suitable location outside Aman city? I've already charged it by you said handing the fortress crystal to Chun Fong who had just returned from that area and was reluctant to make another journey preferring to teleport directly from the main fortress later.

Understood? Chun Foam replied accepting the fortress crystal.

Boss, I want to go too.

I want to see a dwarf, Shinua exclaimed, having never encountered a dwarf or seen a dwarven city.

You two may go together, Bayou said, watching as the siblings entered the portal, heading toward the Bayan mountain range.

Upon arriving at Xiao Liu's castle, the siblings exchanged greetings before embarking towards the northern city of Aman, accompanied by a spectral steed familiar with the route.

The clouds in the sky dissipated completely, revealing the crimson glow of the moon, and darkness enveloped the land.

By you patiently awaited within the palace for the completion of their necroantic fortress.

Chapter 245.

The necropolis fortress time.

2200 hours.

Chunfong and Chinua finally arrived at Aman City.

Contrary to Chun's expectations of grandeur, the city, long under noble dominion, lay in muted silence.

The night enveloped Aman city with only a few scattered houses a glow.

With the departure of Mace and Gray, leading their army of dwarves, the city appeared even more desolate, the siblings chose not to enter the city, but instead sought a suitable location to construct the necropolis fortress.

"It's all grassland around here.

It feels like any spot would suffice," Chenu murmured.

"Let us build it to the south of Aman City within sight.

That way, we want TB2 close yet can provide swift assistance.

" Chunfong suggested thoughtfully.

Agreed.

That was my thought as well.

They continued southward until Aman City shrank to the size of a mere egg in their view before halting.

Shinfong produced the fortress core, accessed the system panel, initiated construction, and casually tossed the core onto the ground.

The siblings then ascended into the sky, distancing themselves from the core's location.

The bones enveloping the core shattered, revealing an interior that radiated an eerie green luminescence.

A colossal magic circle materialized and a white bone fortress began to rise from within it.

The structure was a hexagonal edifice composed of six bone walls with both the walls and the entire fortress crafted from bone.

These bones differed subtly from those forming regular skeletons exuding a peculiar black aura.

The size of the Necropolis fortress exceeded the siblings expectations in comparison to the dwarven guard fortresses.

This one was even larger, spanning a fifth of Aman city area.

The six walls bore no gates.

Instead, at the junctions of the walls stood six round corner towers, each equipped with battlements and strange cannon-like protrusions connected to the towers.

The interior of the fortress was stark, dominated by a towering necromancer spire, suspended at the pinnacle of this tower was the fortress core, forming a transparent, somewhat dark barrier.

This core not only served a defensive purpose but also acted as a sentry tower, automatically targeting and attacking nearby foes.

The siblings landed at top the bone walls which measured 3 m in width.

Though they appeared on the verge of collapse, they were remarkably sturdy.

Each of the corner towers adorned with a black triangular flag.

The siblings pondered the significance of these flags.

Were they functional or merely decorative? The base of the necromancer's tower, situated within the fortress, was also a hexagonal structure.

Five of its six walls were black teleportation arrays, with only one side seemingly accessible for entry.

The five teleportation arrays were angled to enhance their throughput.

The ground inside the fortress was entirely covered in bone, and a staircase ascended from the six walls.

This fortress is rather enigmatic.

Why is there such a vast empty space inside? Chinua questioned perplexed.

Isn't it strange that there are no other facilities? The undead do not require such extravagant embellishments.

Do you expect them to construct homes within? Seizing the opportunity to retort against Chinua.

Chinfong also reached out to Bayou.

Upon receiving the message, Bayou entered the main fortress where she noticed that among the lackluster runes adorning the walls, one had been restored, emanating a vibrant green glow.

Thus, it became evident that constructing a necropolis illuminated a rune.

At that moment, the colossal portal began to radiate light, and Bayou stepped directly into it.

As the portal activated, five other portals within the fortress exuded a dark mist, revealing Bayou's figure before the siblings.

She commenced her examination of the fortress.

Aside from its other functionalities, its size alone could easily accommodate 30,000 dimminionive undead.

Bayou possessed more information than the siblings and first ventured to the corner tower to inspect the undead cannons.

These cannons were integrated with the tower, immmobile and capable of attacking only from fixed embraasers, albeit adjustable in angle.

Curiously, how could they attack without ammunition? Surely they would not expect her to fabricate projectiles.

If so, these cannons might as well be disregarded.

Upon closer inspection, Bayou discovered a hole at the back of the cannon.

Could it be intended for the undead to enter and serve as projectiles? Such a notion was utterly absurd.

Within this corner tower, there were six undead cannons, which Bayu temporarily dubbed scatter cannon ports, as the opposite tower housed only one enormous cannon.

Significantly larger than any she had ever encountered.

This time the opening was not at the back but rather above.
