I opened an adventurer's guild in another world.

"Although an incomplete sacrificial array cannot send seventh or eighth-tier undead creatures over, it can still send a spell over without any problem!"

Sixth-tier magic – [Heart of Curse].

Although not very powerful, it can turn that area into a cursed land.

Perhaps we can also cultivate some powerful undead creatures.

Ah~, has it been almost ten years since the last great war with humanity?

The demons have almost recovered their strength, and it won't be long before the Demon King organizes his next attack.

Hehehe..."

A sinister laugh echoed through the Hall of Bones.

Upon hearing the laughter, the undead guards surrounding the main hall had their soul fire flickering a few times.

......

"Anno, you actually dare to come here?"

Just as Selena was about to confront Anno, the heart suddenly ruptured in the distance.

The eerie and sinister atmosphere sent a chill down everyone's spine.

When Tester saw the black shroud rapidly expanding from the location of his heart, he felt a pang of fear and quickly took out the sealing crystal containing the magic from his pocket.

"Selena, come closer!"

The sharp-eyed Anno spotted the crystal in Tester's hand and quickly rushed to their warhorses.

The next second, darkness descended.

The crystal in Tester's hand shattered, and a gigantic, four-winged angel, ten meters tall, wielding a sword, materialized above Tester.

Fifth-tier light magic – [Angel's Protection]!

The four-winged angel radiated a dazzling white light, raising its greatsword as if to cleave through the overwhelming darkness.

Protected below by the four-winged angels, Tester, Anno, and the others were not affected by the darkness at all; on the contrary, their bodies felt warm under the white light.

Anno felt that all the physical strength he had previously expended had been restored.

However, only Tester's forty-odd guards were protected by the four-winged angels.

As for the guards outside, they had been swallowed by darkness, and their condition was not visible.

To Tester's dismay, the four-winged angel above seemed unable to resist the darkness; its lightsaber was gradually being swallowed by the black room, and the area shrouded in white light was rapidly shrinking.

Moreover, the white feathers and armor of the four-winged angel began to be eroded by the darkness.

The entire phantom appeared somewhat fragmented.

After holding on for two minutes, the four-winged angel shattered.

Its body fragments coalesced into a light shield that protected everyone above.

As the light barrier cracked and teetered on the brink of collapse, the darkness that had lasted for almost three minutes finally disappeared.

Anno let out a long breath.

Only then did he realize that his back was soaked with sweat while he was fighting against the four-winged angel and the darkness.

Not only Anno, but even Tester felt like he had survived a disaster.

The heart exploded five seconds after it was transmitted, and the rapidly spreading darkness gave everyone no time to escape.

If Tester hadn't possessed the Demon-Sealing Crystal and activated his protective barrier in time, everyone would have been exposed to the darkness.

It could barely withstand even fifth-tier magic; exposed to the darkness, it would probably die very quickly.

The darkness disappeared, and the light barrier couldn't hold on any longer, flickering three times before vanishing.

Tester looked at the cracked Demon-Sealing Crystal and felt extremely distressed.

The magic sealed inside can only be used once; it was a gift from the king to Tester during his coming-of-age ceremony.

It is also Tester's biggest trump card.

But now that trump card has been used up.

However, the Demon-Sealing Crystal is an extremely precious material.

Even if it cracks, it still has extremely high recycling value.

So Tester didn't discard it, but instead stored it in his storage ring.

Anno witnessed this scene and immediately deduced that it was a storage device.

Anno urgently needs storage equipment due to the need for summoning materials.

However, now is not the time to ask how to obtain storage equipment.

Around the crowd, the hundreds of guards who were not protected by the "Angel's Protection" all looked completely different.

They were pale, with only the whites of their eyes showing, and their movements were rather stiff.

Most importantly, under the [Five Perspectives Omnipotence] assessment, the racial information of these soldiers was changed to that of the undead zombie race.

Even the warhorses have turned into zombie warhorses.

These guards, who served as Tester's protectors, were all level 15 in life, with some even reaching level 16.

After being turned into undead, their level remains the same as when they were alive.

But Anno discovered that their health was ridiculously high.

Race: Undead Zombie

Rating: 15

Occupation: Warrior

Health: 15000/15000 (Enhanced in the Cursed Lands)

Mana: 2500/2500

Skills: [Dead] [Infection] [Basic Swordsmanship] [Sweep] [Vertical Slash] [Continuous Thrust] [Savage Charge] [Sword Aura Shot] [Resistance Boost]

The level 15 soldier still alive next to Anno has only about 10000 health points.

However, these zombie soldiers all have at least 15000 health points!

Besides the nearby zombie soldiers, Anno noticed a large number of figures rushing toward them from a distance.

It wasn't just the prince's guards around Anno who were turned into undead.

The two thousand soldiers who failed to retreat were all turned into undead!

Ninety-nine percent of the monster troops on the other side were within the range of the black shield.

"Oh my god, what happened?"

Selena stared at the ground around her, her eyes filled with fear.

Just now, there were flowers and grass growing on the ground.

At this moment, the ground was devoid of any life, turning into a barren, black earth.

Black smoke continuously drifts out from some of the cracks.

Within the area shrouded in darkness, except for a small patch of land beneath Anno and the others' feet, everything else had become a hellish scene.

This last remaining "pure land" is now being constantly assimilated.

When flowers and plants are tainted by the black aura, they wither rapidly and turn into ashes within seconds.

"This is a cursed land!"

Tester took a deep breath, fear evident in his eyes.

"Retreat immediately! Humans trapped in this cursed land will be corrupted both physically and mentally. Over time, they will lose consciousness and become undead! Retreat!"

Anno was taken aback when he heard Tester's explanation.

Was the purpose of that transmitted heart to turn this place into a cursed land?

"Your Highness... Commander Duke... and the others seem to be acting strangely!"

A soldier, holding a long sword, looked at his former comrades around him, but now he seemed strange, even his reports were somewhat incoherent.

Duke's strength is level 16, which is equivalent to a commander of a thousand men in the army.

He was just on guard duty outside the perimeter of the guard team, but now he has also been turned into an undead zombie.

"Your Highness, these soldiers have all turned into undead zombies; they are dead!"

Anno was explaining this to Tester, but also to the guards around him.

With so many undead and zombies outside, Anno didn't want the surviving guards to foolishly rush forward because of feelings of camaraderie or something similar.

Moreover, the undead's [Infection] skill caught Anno's attention.

If these undead zombies can infect humans, then we're in big trouble.

Even though Tester's guards were all elites, with more than a dozen at level 16 or above, the rest were just level 15 guards.

But if they accidentally get infected, these guards will become enemies!

Surrounded by hundreds of undead zombies, with thousands more on their way in the distance.

Even though Tester was level 20, being caught in the zombie horde meant certain death!

He drew his longsword from his waist and shouted to everyone, "Everyone, protect me! Break through!"

Anno grinned; the current situation was extremely dangerous for someone who was only level 11.

Once he's separated from the breakout group, he's finished.
