I opened an adventurer's guild in another world.

Warreng!

Inside a building in the city, Xue Feibai and his companions were resting against a corner of the wall.

As the sun rose, a weary-looking Anno led his men back from the front lines and pushed open the door to enter.

"Anno, are you alright?"

Liu Rongrong and Ning Wen immediately began to examine Anuo's injuries.

"I'm fine!"

Anno waved his hand, then found a chair and sat down.

Anno's return startled everyone in the house.

Besides Xue Feibai and his group, there were also Sun, Jinmu, and Yinmu.

"How's it going up ahead?"

Upon seeing Anuo return, Xue Feibai immediately asked.

"The undead legion has temporarily retreated, but they are expected to resume their attack tonight. The priests suffered heavy losses last night; they will likely need to request reinforcements from the Holy Church!"

Anno briefly explained the situation, then lay down on the straw mat in the corner and fell asleep.

Liz and Ella nestled close to Anno, and soon the sound of their steady breathing filled the air.

Sasser was asleep outside the door.

Yesterday evening, after the remnants of the monster army fled in panic, the undead legion arrived two kilometers outside the city.

An army of 100,000 undead began its attack on Volungol.

Anno immediately focused his consciousness on Asar, only to find that Asar was unconscious.

After controlling Asar's body and opening his eyes, Anno saw himself being held by a pair of huge bone hands, and not far to the side was a dark figure sitting on a bone throne.

The owner of the giant bone hand and the shadowy figure seemed to sense Asar's unusual behavior and turned to look at him.

The moment Anno was about to meet the soul fire flickering in the shadowy figure's eye sockets, he sensed immense danger.

He quickly regained his consciousness and immediately recalled Asa!

The Lich King and the eighth-tier undead overlord were left deep in thought.

Anno, having regained consciousness, prepared to check on Asa's condition.

As soon as it was summoned, it turned into white light and slowly dissipated.

Anno acted swiftly.

However, the Lich King's subordinates, the eighth-tier undead overlords, also possess many tricks up their sleeves.

After realizing he couldn't control Asar, the Undead Overlord put Asar into a coma, intending to study him later and see if he could pinpoint the opposing 'Lich'.

In addition, the Undead Lord also unleashed a skill on Asar.

Even though Anno summoned Asar back, several kilometers away, and the skill was activated, Asar was still dead!

Anno felt a pang of sadness as he watched Asa vanish into white light while unconscious.

This is Anno's first Tier 4 summon as he enters the mid-tier.

He used to be Tester's subordinate!

"Perhaps... I should have freed you long ago!"

Anno picked up the fine steel longsword he had given to Asar and put it into his storage ring.

At this moment, Anuo, Xue Feibai, and the others were at the breach in the city wall, preparing to resist the army of the undead.

But to everyone's surprise, the entire city wall fell in just three hours.

The reason is that the area around the city walls has been transformed into a high-level cursed land.

Human soldiers were unable to fight on the walls and had to abandon them and retreat.

Even high-ranking priests cannot dispel the high-level cursed earth in a short time.

What puzzled the high-ranking priests in the city was that transforming land into high-level cursed land was not something that could be done overnight.

Ordinary land needs to be transformed into low-level cursed land first, then it takes a period of time to become mid-level, and finally high-level!

The undead calamity in the Southern Territory caused by the lich only affected the low-level Curse of the Earth.

Even if the Lich King is an eighth-tier being, it would still require the coordination of the entire undead army and ten to fifteen days to transform the land within the city walls into high-tier cursed land.

But this time, it only took three hours to evolve into a high-level cursed land.

Even high-level professionals must expend a great deal of energy to resist the black energy of the cursed land in the high-level cursed land, and can only exert 70% or 80% of their strength at most.

Lower-level creatures, without special means, will be transformed into zombies within tens of seconds if they stand on high-level cursed land!

In just three hours, the Lich King transformed a vast area around the city walls into a high-level cursed land, leaving the defenders on the walls with almost no time to retreat!

It was at that time that the high priests in the city vaguely realized that all of this might be related to the Lich King's previous order for the monsters to attack the city and die.

But there is only one Lich King in the world, and he is an enemy.

No one knows what methods it has or how it managed to do this.

In fact, the Lich King sent scattered demonic forces to attack cities for two reasons: first, to deplete the city's power reserves; and second, to accumulate the resentment and souls of the dead.

Monster troops are different from undead legions.

The former are the living, while the latter are the undead.

The cursed earth absorbs resentment and souls, evolving dozens of times faster than it absorbs death energy!

Undead that are transformed by the cursed land will instinctively kill living beings to provide 'nutrients' for the evolution of the cursed land.

Moreover, the higher the level of the cursed land, the greater the chance it is of giving birth to high-level undead over time.

Warrenger would collect and burn most of the corpses left behind by the monster army after each attack.

While this would prevent the Lich King from using the corpses again, it would not solve the problem of the resentment generated by the dead.

The siege lasted for nearly a month, and the number of monsters that died near the city walls was at least 80,000 to 100,000.

This doesn't even include the number of human deaths!

The resentment left behind by the deaths of nearly 100,000 people, plus the souls who didn't have time to go to the underworld in the last war.

According to the Lich King's plan, a large area of ​​land could be transformed into a high-level cursed land in half an hour.

But when it came to actually implementing it, the Lich King discovered that there were very few souls on the battlefield!

Theoretically speaking, the soul will remain for at least an hour before dissipating.

There's no reason for them to be sucked away by the underworld so quickly!

Due to the limited number of souls, the conversion time has increased to three hours.

The Lich King kept the matter of the missing soul to himself for the time being, planning to go to the Underworld to check on the situation later.

The main objective now is still to break through Vörenger.

Because the high-level cursed earth had taken shape, the undead army captured the city walls without any hindrance.

Furthermore, the undead have a power boost on the cursed land, and the priest's holy light magic is greatly reduced in power when it falls on the cursed land.

The soldiers defending the city didn't even dare to retake the city walls and could only retreat inside the city.

Without the city walls and facing a fierce attack from the undead legion in the middle of the night, the city's defenders suffered heavy casualties. The spread of the cursed land was not too fast, and the undead legion's offensive was launched outside the range of the cursed land.

Especially pastors.

Once the undead spotted the priest on the battlefield, they all rushed towards him in a frenzy.

Anno saw several mid-level heavy armor priests from the Holy Church being surrounded and killed by skeletons, zombies, and liches on the battlefield, which is why Xue Feibai and the others, who were exhausted, took Liu Rongrong and Ning Wen and retreated first.

The soldiers and adventurers who participated in the defense of the city during the day almost all retreated to the rear to rest in the latter half of the night.

The troops that had not been deployed earlier were the main force that fought the undead legion in the latter half of the night.

Because Anno mainly relies on summoned creatures to fight, his own stamina consumption is not high.

However, Shadow was killed by a fifth-tier skeleton knight with a bone spear!

Fortunately, Anno was nearby and used his storage ring to retrieve the magic set.

[Poisonous Fungus] is useless against undead, otherwise Anno could quickly clear out low-level minions.

With 100,000 dead, Anno alone cannot turn the tide.

However, every soldier fought with all their might to defend the rear.

Anno didn't have many mana potions left, and he barely drank any during the battle in the latter half of the night.

They all use the fourth-tier [Clarity] and [Devour Rebirth] spells to slowly recover mana, and then summon skeletons and zombies to fight for them.

When the reserves of [Devouring Reincarnation] ran out, he had to take on several lich necromancy spells head-on.

Throughout the entire night, Anno lost count of how many skeletons he killed and how many zombie souls he absorbed.

All he knew was that he had broken through to the fifth rank in the early hours of the morning, before the undead army retreated!

Moreover, after reaching the fifth rank, Anno discovered that he had more than five hundred fifth-rank souls.

There were more than two hundred sets of fifth-tier sacrificial materials piled up.

The number of summoned creatures for [Spirit Offering] has increased from eighty to one hundred and sixty!
