Lord: My troops can evolve indefinitely.

A continuous, dark gray wave, composed entirely of undead forces, crashed against the walls of Blackrock Territory.

Low-tier units such as skeletons, rotting corpses, and ghouls launched wave after wave of attacks, constantly eroding Blackrock Territory's defensive strength.

At the very front were the skeleton soldiers, the lowest-ranking cannon fodder. Their pale bones made a sickening "crackling" sound as their bodies were shattered before they even got close to the city walls.

However, with the skeleton soldiers providing cover and drawing fire, the rotting corpses and ghouls that were positioned further back quickly pressed forward.

Countless rotting corpses dragged their festering bodies forward, their foul-smelling bodily fluids dripping from their wounds and staining large swaths of the surrounding land black.

The ghouls, with their terrifying sharp teeth and fangs, were all deep black, and using their skeletons and corrosive bodies as cover, they silently approached the walls of Blackrock Territory.

Then it raises its claws to attack the shield, or simply opens its mouth and bites at the shield.

In an instant, numerous ripples representing an attack spread out across the protective shield.

The shield's energy bar began to drop sharply.

"Defend! Quickly clear those ghouls out!"

The commander standing on the city wall roared, and then countless arrows, stones, and spells followed his command and rained down on the ghouls.

Instantly, blood and flesh flew everywhere at the foot of the city wall, clearing a small clearing in an instant.

However, before the Blackrock Territory's defenders could even catch their breath, more undead troops were already pressing in, giving them no chance to breathe.

This is the most terrifying aspect of the Scourge: its supposedly endless army of undead capable of wearing down almost any territory.

Moreover, small groups of undead forces continued to join the undead army from the surrounding plains.

Looking at the seemingly endless army of undead, Luo Xuan could imagine how desperate and powerless the defenders must feel.

This is just the undead's low-level ground forces; it's clearly still in the probing and attrition phase.

Behind the entire battle line, several enormous skeletal beasts were mixed in with the undead forces; their massive size made them easy to spot at a glance.

They picked up the boulders that the other undead units had specially carried over from the surrounding ground, and then their skeletons swung, hurling the boulders toward Blackrock Territory.

Because of the activated protective shield, the skeletal behemoth didn't even need to aim; it only needed to throw in the general direction.

Luo Xuan even witnessed a skeletal behemoth, having run out of stones and before the replacements arrived, grabbing two nearby rotting corpses and hurling them away.

The two rotting corpses were like miniature figurines in front of the enormous skeletal beast, easily tossed aside.

Luo Xuan used his reconnaissance skills to check the information about the skeletal behemoth and discovered that it was a special undead created by a lich using necromancy.

Slow-moving and with weak defenses, these are special undead created specifically for siege warfare.

Upon seeing the introduction, Luo Xuan felt a chill run down his spine.

At this moment, he remembered the information Zhou Fa had told him before—that each undead stronghold was led by a high-ranking death knight or lich.

Clearly, the undead forces attacking Blackrock Ridge were once part of an undead stronghold commanded by a lich, and gradually grew to their current size.

Thinking of this, Luo Xuan couldn't help but feel a surge of relief. Fortunately, he had cleared out the undead stronghold in the northern wilderness before, otherwise he would have faced the same siege of the undead army as Blackstone Territory.

This also explains why so many undead troops kept emerging from the undead stronghold back then.

Luo Xuan continued looking, and further behind the skeletal behemoth, high-ranking undead knights were arrayed in neat formation, ready to charge at any moment.

Nearby, necromancers stood outside the range of the magic-absorbing tower, waving bone staffs that emitted eerie green flames and chanting obscure necromancy incantations.

Huge, dark green fireballs were continuously hurled at the Blackstone Territory's protective shield, creating massive ripples.

"Quickly supply elemental crystals to provide energy; the protective shield is about to collapse!"

A mournful roar echoed from within Blackrock Territory, and the mage apprentices inside the Magic Absorbing Tower hurriedly carried boxes upon boxes of elemental crystals into the tower.

The magic-absorbing tower, having absorbed a large amount of magical energy, stabilized the previously crumbling protective shield.

"My lord, this can't go on. We'll be worn down by the undead sooner or later."

Upon hearing this, the lord of Blackrock Territory frowned.

Although Blackrock Territory is an old territory, it can be said to be a large and powerful one.

However, even they do not have much reserve of elemental crystals.

At the current rate of energy consumption, the magic tower's protective shield will soon shut down automatically due to lack of energy.

Normally, the Magic Absorbing Tower would automatically absorb the magical energy of the troops on the battlefield.

However, undead units are low-tier units such as skeletons, rotting corpses, and ghouls, which have no magic to absorb, so they can only rely on their internal energy reserves for replenishment.

Luo Xuan was unaware of this; he only witnessed the fierce siege battle between the two sides.

Along the edges of the protective shield and the city walls, undead units have left behind piles of bones.

However, even so, more and more undead forces continued to attack Blackrock Territory.

"Catapult aim, target the mage unit in the distance!"

On the city wall, the commander of the Blackrock Territory was giving loud commands, trying to eliminate the undead's artillery mages.

"Boom!"

With a series of deafening roars, giant catapults standing behind the city walls launched stones the size of millstones.

However, the boulders that were launched by the catapults were quickly intercepted by the gargoyles hovering in the sky.

These gargoyles, fearless of death, deliberately crashed into the flying boulders, using their own bodies to withstand the stones.

Despite being severely injured, the gargoyle quickly recovered after landing and transforming into its stone statue form.

Only a few unlucky souls were struck by multiple boulders in mid-air and died instantly before they could even land.

The boulders intercepted from the air also deviated from their original target, falling into open areas or among groups of low-level undead units.

Upon seeing this, Luo Xuan's eyes narrowed. Clearly, there was a commander among the undead forces, and he was quite intelligent and quick to react.

They even anticipated the attack from Blackrock Territory and prepared countermeasures well in advance.
