Northrend Continent, Icecrown Glacier Region, Icecrown Fortress.

With a roar, the heavy iron gate of the Icecrown Fortress was slowly opened.

That's right, it's the kind of goblin engineering product called "Gate Ripper" that pulls it apart.

The Gate Ripper is a machine that is simply a large arcane crystal and steam-powered engine, which violently pulls open the tightly closed gates through two levers with strong suction and the power generated by the engine.

Then it was time for the elite advance team to show their skills, and they skillfully fought their way through the army of mid- and high-level undead that poured out of the Icecrown Fortress as they had rehearsed countless times in the Silver and White League camps, and went straight to the inside of the fortress.

As the lair of the Lich King, the undead calamity in the Icecrown Fortress is naturally different from the outside, and the lowest is also a mid-level undead, not the kind of expendable cannon fodder that directly resurrects and then immediately pulls onto the battlefield outside.

The main forces of the Silver Northern Expeditionary Army and the Scarlet Vanguard Army firmly captured the attention of the fortress's elite undead forces to ensure that the advance squad faced as few enemies as possible.

The commander of the advance team was Princess Kalia, and Gianna volunteered to serve as her deputy.

At this moment, these two fierce girls led the elite soldiers and adventurers selected from various ethnic groups and forces all the way to the depths of the fortress.

Where they were now was in a long corridor behind the Icecrown Fortress, and a few dozen meters away, a wide hall filled with cold air could be faintly seen.

The task of the advance team was to establish a front-line stronghold and defense line in that hall, and to advance the main battlefield into the interior of the fortress, so that the undead could not be defended.

Princess Kalia held aloft the golden artifact sword "Dawn Morning Light", and the restored princess rushed to the front, slashing left and right at the undead around her. With the amplitude of the continuous swing, the golden sword body also continued to exude sharp energy sword qi, shooting towards the enemy that the long sword could not slash at farther away.

Gianna, the mage, followed closely in the advance team, waving her staff to control the violent blizzard in front of the team to move forward.

The closer you got to the hall in front of you, the more enemies poured out from all directions, as if the undead forces that were fighting the Northern Expedition outside the fortress at the moment were just a partial division.

The advance party finally stepped into the vast hall, but the high-ranking undead here put them in a bitter battle.

Seven or eight lichs floated in mid-air, directing a large number of undead guards and crypt spider demon charges, while unleashing various shadow and frost spells with high-ranking skeleton mages.

"Hold them off, or I won't have time to place the crystals!" Princess Kalia unleashed a dawn sentence again, and a huge dark golden sword qi roared out from the Excalibur, and then moved towards the undead in front of her like a steamroller.

"Doing ... Gianna gritted her teeth and joined forces with the mages of the advance team to unleash a sturdy wall of ice, constantly pumping mana at the litigants within, keeping the wall from being shattered by the lichs.

A flesh giant staggered over to the ice wall, roared and raised his rotting fists and began slamming into the ice wall.

At that moment, a scarlet lightning bolt rushed down the hallway, and the slender figure in the lightning jumped lightly onto the shoulder of a mage, and then kicked hard over the towering ice wall.

The demon knife girl fiercely swung out the long-stored scarlet demon knife, and slashed at the waist of the flesh giant with a surging demon aura.

The giant had been cut in half as if it had been cut into tofu, and its upper body fell heavily to the ground, still letting out an inexplicable roar.

The girl jumped on the flesh giant's head and slammed the two-meter-long demon knife into the back of the giant's head.

The soul fire was immediately sucked out along the blade of the demon knife, strengthening the demonic energy in the girl's body.

The dark clouds composed of scarlet demonic qi filled the hall, and as the girl followed closely with the successive slashes, the demonic qi clouds turned into sharp tentacles, overwhelmingly attacking the surrounding undead.

Some of the demonic energy that was not absorbed by the demon sword Ji condensed into demonic resentful spirits, screaming and pounced on former undead colleagues, or unleashed one after another resentful spirit arrows.

"Quick, put that crystal of yours!" the girl shouted to Princess Kalia, and then continued to ride a thousand, summoning demonic wraiths while using combo slashes to shuttle between the high-level undead.

Princess Kalia didn't hesitate, quickly found a suitable platform, and began to install the "artificial small Naru essence" produced by the Night Empire's Sleeping Tower. ”

The scholars of the Holy Cult Army have now come up with a lot of information and breakthroughs about the Naru core by studying the two Naru who were captured and imprisoned.

While there is still no clue as to how Naru managed to make light and darkness coexist, at least progress has been made on the light.

This small crystal is simply a crude artificial Naru core, and it only has the single function of generating holy light, and its strength is also unchangeable, and its durability is not long, let alone evolving into a Naru.

Although the experiment failed, the Night Empire began selling the artificial Naru essence in the spirit of waste utilization, and it was immediately welcomed by paladins around the world.

It's a good thing for them! Buy one and put it in your church or camp, and it's so nice to have as much light as you want!

Moreover, this thing is also a nuclear bomb-level killing weapon for the undead, as long as the crystal has not been scrapped, the fierce holy light radiance emitted from it can burn any undead to ashes.

Of course, this artificial light purification does not have the effect of healing allies.

This is not surprising, after all, the makers are a group of people who do not believe in the Holy Light at all, and with the mentality of purposefulness and war machine, they have created one Holy Light Crystal after another. Therefore, the holy light in it is sharp and merciless, and the light of punishment is the essence of all.

Naru and the Vereon Padraenei had always wondered how the Night Empire could have created such a holy light crystal that should not exist in the world, and that defied the common sense of nature.

Can the Light still be mechanized?

Heaven and earth can be learned, it is impossible for those Holy Cult soldiers to believe in the Holy Light! Since they do not believe in the Holy Light, how did they create such a crystal that can produce the Holy Light?

Following the step-by-step instructions, Kalia quickly completed the crystal installation.

The Artificial Naru Essence immediately floated from the base, rotating clockwise in mid-air.

Forthwith...

A circle of holy light spread out from the crystal like a tsunami, and enveloped the entire hall precisely according to the range set by Princess Kalia in advance.

The lichs immediately retreated in horror, the ice shields around their bodies burning violently with the light of punishment.

The lichs are clever and quick to withdraw. But the other undead who are still in the hall aren't so smart.

They didn't take it seriously at first, and continued to attack Gianna's ice wall and the demon knife girl who wielded a scarlet knife and shuttled between them.

Soon, however, their bodies began to smoke, followed by golden flames.

The flames of punishment burned their bodies.

A moment later, there was not even a single undead in the entire hall, and even the small undead insects in the corners and crevices were burned into a puddle of ashes by the retributive light that permeated the hall.

On the battlefield, only the Demon Sword Maiden was left walking around, absorbing the remaining soul fire.

Gianna withdrew the ice wall and gasped heavily.

The elites of the advance team were stunned for a moment, and then let out excited cheers.

They had completed their mission, and the entrance hall of Icecrown Fortress was now theirs.
