A series of explosions continued to sound on the ground under the blood moon and the bright moon.

Click!

The magic sword in Osiris's hand broke, and the soul fire in his eyes gradually went out.

After its huge body fell to the ground, it looked up at the black-armored knight in front of it and begged for mercy: "I have already told you about the mines of Ghost Bluestone, why don't you let me go? As long as you don't kill me, I can give you this city of the dead!"

Being in the domain of the Evil King, Osiris had no chance of escape.

Anno heard Osiris's plea for mercy and shook his head silently.

Then he swung the dragon scorpion tail cannon sword in his hand and chopped it down heavily.

Osiris' skull was smashed in an instant.

The soul fire in the eye sockets jumped twice and then completely dissipated.

Anno picked out a part of the body and sacrificed Oslis's soul.

"Master, what do you want?"

Looking at the huge skeleton more than five meters tall leaning down in front of him, An Nuo thought to himself: It would be great if the summoned creature could retain its memories before it died.

"When you go out later, pretend to be hostile to us. For the next period of time, don't meet other people and slowly get familiar with your identity!"

"clear!"

Osiris nodded.

Anno's intention was to let Osiris pretend to be the original city lord and then stay here to serve as Anno's spy.

Moreover, according to the information provided by Osiris before his death, there is a ghost bluestone mine less than fifty kilometers away from his city of the dead.

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

But unfortunately, after entering the City Lord's Mansion before Annuo and discovering that Osiris had set an ambush, Osiris was doomed to die.

…

outside world!

A group of skeletons of all sizes were about to rush towards the lich and its servant, the black-armored knight.

As a result, in the blink of an eye, the two men and their city lord disappeared from the hall.

The skeletons searched for about five minutes before the three men reappeared in the hall.

However, the city lord seemed to be seriously injured, with several ribs broken, and the lich's clothes were tattered - before coming out, the two summons were slightly disguised.

Although I am curious about what happened during the time when the three people disappeared.

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

"stop!"

Osiris' voice echoed in the hall.

All the surrounding skeletons turned around and looked at their city lord.

“Let them go!”

Osiris' tone was as if he had found a tough bone to chew and had no choice but to let the other party leave.

Skeletons, you look at me, I look at you.

Before the lich came in, he used magic to destroy the forbidden magic circle in the hall, obviously seeing through Osiris's thoughts.

And the fact that the lich could injure Osiris into this state shows that he is indeed very powerful.

"I hope you can be calmer next time and don't attack a lich so rashly!"

The lich pretended to be very angry and left a few words, then turned around and left with An Nuo.

"Lord City Lord, what happened?"

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

Osiris did not answer, but said: "I was seriously injured this time and need to adjust. Don't call me if you have nothing to do!"

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

An Nuo, who had returned to Liz and the others, looked back at the City of the Dead behind him and murmured, "It looks like there are no flaws!"

It’s not that he doesn’t have the ability to directly capture the City of the Dead.

But there are too many troubles to deal with afterwards.

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

It won’t be long before a large number of undead come to conquer us.

The underworld is not some other plane.

This place is slightly more dangerous for humans.

If it weren't for Gui Qingshi, Annuo really wouldn't have set up the first stop here.

For this reason, when Annuo sent out invitations to other worlds, he only invited sixth-level adventurers and adventure teams.

According to Annuo's next plan, Osiris will stay in the City of the Dead before being exposed, providing Annuo with intelligence and certain cover.

And Annuo will establish a secret base in the mine where the ghost bluestone is located, build a plane teleportation array, and guide the adventurers from Angomlos.

…

"Is this the place you were talking about?"

Philomena looked at the barren mountain in front of her that was covered with strange plants and nodded, "The concealment is pretty good. Several mountains are over 500 meters high. It's easy to find an inconspicuous place to build a plane teleportation array!"

"The mountain in the center has ghost bluestone in the mountain."

An Nuo explained: "We built the teleportation array nearby so that it will be easier to mine when the time comes."

As long as we can mine the ghost bluestone, this trip will not be in vain.

"Master, do we need to clear out all the zombies and skeletons in the mountains?"

Sasir asked, sticking out his tongue.

"I don't think it's necessary."

Before Anno could answer, Philomena replied, "Leaving these low- and mid-level undead behind is just right for the adventurers to practice with."

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

"plant?"

Philomena pointed at the white tree and said, "This is the giant bone tree from the underworld. Next to it are the blood corpse flower, the corrosive vine, and the soul-bewitching grass. They are all monsters from the underworld!

Ordinary undead creatures don't dare to mess with it."

"Philomena is right, but there is no threat to us!"

The panel data of those monsters were already displayed in Annuo's eyes, and then he walked over with Liz and Sasier.

Seeing this, Philomena wrinkled her nose at Anno's back and followed him.

Those underworld plants are extremely troublesome at the mid-level, but for the high-level ones, the danger level is not that great.

After the group found a suitable area, Annuo asked Philomena to start building an inter-dimensional teleportation array and left behind a large number of summoned creatures to assist.

And Annuo himself rode Sasir to the mountain with the ghost bluestone.

"Master, there is a cave there."

Sasier walked around the mine for a while and suddenly found a hidden small cave in front of him. He ran over excitedly.

Anno searched around the mine and found a little white sticking out from a pile of sand.

Swoosh~!

Anno drew out the magic sword and poked the white area with the tip of the sword.

Crash!

The white area suddenly moved to avoid the magic sword, and the sand covering it scattered, revealing a skeleton hand.

"Sir, don't kill me, don't kill me! I just found this ghost bluestone mine and haven't started digging yet, haven't started digging yet!"

As if knowing that it had been exposed, a skeleton only about 1.5 meters tall stood up from the broken soil, and knelt in front of Anno with a "bang".
