I opened an adventurer's guild in another world.

A series of explosions rang out across the land beneath the blood moon and the bright moon.

Click!

The magical longsword in Osiris's hand snapped, and the flame of his soul in his eyes gradually died out.

After its massive body collapsed to the ground, it looked up at the black-armored knight before it and let out a soft plea for mercy: "I've already told you about the Ghoststone mine, why won't you let me go? If you don't kill me, I can offer you this city of the dead!"

Being inside the Evil King's domain, Osiris had no chance of escape.

Hearing Osiris's pleas for mercy, Anno silently shook his head.

Then he brought down the Dragon Scorpion Tail Cannon Sword with a heavy slash.

Osiris's skull was smashed instantly.

The flame of his soul flickered twice in his eye sockets before completely dissipating.

Anno casually picked out a part of the corpse and then sacrificed it to Oslis's soul.

"Master, what are your orders?"

As the giant skeleton, over five meters tall, bent down in front of him, Anno thought to himself: If only the summoned creatures could retain their memories from their previous lives.

"After you leave, pretend to be hostile towards us. For the next while, don't see anyone else; slowly familiarize yourself with your identity!"

"clear!"

Osiris nodded.

Anno's idea was to have Osiris impersonate the original city lord and stay there as Anno's informant.

Moreover, according to information provided by Osiris before his death, there was a Ghoststone Mine less than fifty kilometers away from his city of the dead.

In order to survive, it even revealed the specific location.

Unfortunately, once Anno entered the city lord's mansion and discovered that Osiris had laid an ambush, Osiris's death was inevitable.

......

outside world!

A group of skeletons of all sizes were about to charge at the lich and his black-armored servants.

In the blink of an eye, the two of them, along with their city lord, disappeared from the main hall.

After the skeletons searched for about five minutes, the three reappeared in the hall.

However, the city lord seemed to be seriously injured, with several of his ribs broken, while the lich's clothes were tattered—the two summoned creatures had disguised themselves slightly before coming out.

I'm curious about what happened during the time the three of them disappeared.

But at this point, the skeletons knew to deal with the lich and the black-armored knight first.

"stop!"

Osiris's voice echoed throughout the hall.

The surrounding skeletons all turned to look at their city lord.

"Make them leave!"

Osiris's tone suggested that he had found a tough nut to crack and was forced to let the other party leave.

The skeletons looked at each other.

Before the lich even entered, he used magic to destroy the magic-blocking array in the hall, clearly having seen through Osiris's intentions.

Furthermore, the fact that the lich was able to injure Osiris to this extent demonstrates that the lich is indeed very powerful.

"Next time, I hope you'll be more composed and not attack a lich so casually!"

The lich pretended to be very angry, left a sentence, and then turned and left with Anno.

"Lord City Lord, what has happened?"

After the lich left, a skeleton soldier turned and questioned Osiris.

Osiris didn't answer, but said, "I'm badly injured this time and need to recover. Don't call me unless it's absolutely necessary!"

After saying this, Osiris ordered all the skeleton soldiers to leave the hall.

Having returned to Liz and the others, Anno glanced back at the City of the Dead and murmured, "Looks like they didn't give anything away!"

He wasn't lacking the strength to directly seize the City of the Dead.

However, there are too many troubles to deal with afterward.

Once other passing undead discover that the city has been occupied by humans.

Before long, a large number of undead will come to conquer them.

The underworld is not another dimension.

This place is slightly more dangerous for humans.

If it weren't for the Ghost Blue Stone, Anno wouldn't have chosen this place as the first stop.

That is why Anno only invited sixth-tier adventurers and adventurer groups when sending out invitations to other worlds.

According to Anno's next plan, Osiris will stay in the City of the Dead until he is exposed, providing Anno with intelligence and some cover.

Anno will establish a secret base in the mine where the Ghoststone is located, build a dimensional teleportation array, and bring in adventurers from Ungomulos.

......

"Is this the place you were talking about?"

Philomena looked at the desolate mountain in front of her, covered with strange and eerie plants, and nodded, saying, "The concealment is decent. Several mountains are over 500 meters high, making it easy to find an inconspicuous spot to build a dimensional teleportation array!"

"The mountain in the very center contains the Ghost Blue Stone."

Anno explained, "We'll build the teleportation array nearby so it'll be easier to mine later."

If we can mine the Ghost Bluestone, this trip will not have been in vain.

"Master, should we clear out all the zombies and skeletons in the mountains?"

Sassi asked, sticking out her tongue.

I don't think it's necessary.

Before Anno could answer, Philomena replied, "Leaving these low- and mid-level undead is perfect for adventurers to practice on."

Liz nodded, then pointed in a direction and said, "There are more plants in that area; hide the portal there."

"plant?"

Philomena pointed to the large, white tree and said, "This is the giant bone tree of the underworld. There are also blood corpse flowers, corrosive vines, and bewitching grass next to it. They are all monsters of the underworld!"

Ordinary undead creatures wouldn't dare to mess with them.

"Philomena is right, but they pose no threat to us!"

Anno had already seen the data panel of those monsters in his eyes, and then he led Liz and Sassi over.

Seeing this, Philomena wrinkled her nose at Anno's retreating figure and then followed him.

Those underworld plants are extremely troublesome for mid-level players, but they are not that dangerous for high-level players.

After the group found a suitable area, Anno had Philomena begin setting up an interdimensional teleportation array, leaving behind a large number of summoned creatures to assist.

Anno himself rode Sasser to the mountain with the ghostly bluestone.

"Master, there's a cave over there."

Sasser walked around half of the mine and suddenly discovered a hidden little hole in front of her. She ran over excitedly.

Anno searched around the mine and then found a small white spot peeking out from a pile of sand.

Whoosh!

Anno drew his magic sword and poked the tip into the white area.

Whoosh!

The white area suddenly shifted to avoid the demonic sword, and the sand covering it scattered, revealing a skeletal hand.

"My lord, please don't kill me! Please don't kill me! I just found this Ghost Bluestone mine, I haven't even started digging yet!"

As if realizing that he had been exposed, a skeleton that was only about 1.5 meters tall stood up from the rubble and knelt down in front of Anno with a "thud".
