In the middle of the night, the mine seemed to be particularly cold, and there was an inexplicable cold wind that blew out of the ground, making people shudder.

Xu Ping'an and the rescue adventurers who formed a long queue followed Li Fei, constantly passing through the complex and winding mines, getting deeper and deeper, and leaving fewer and fewer traces of adventurers along the way.

Are you already familiar with the terrain of the mines?But is your purpose really just to explore the boss's lair? Are the disappeared and missing adventurers related to you?

Xu Ping'an looked at Li Fei's back and couldn't help but think so.

As mentioned earlier, the underground space of this black iron ore cave is extremely complex and huge, more extensive than the island on the ground, and there are countless tunnels, up and down, if you want to be like Li Fei is leading the way now, move forward quickly, and not take the wrong path, it is definitely not something that can be remembered by exploring a few times, at least it takes a few months, more than a dozen times a day, or even dozens of times of back and forth exploration to be possible.

And spending months and exploring such a huge and complex underground cave at any cost requires an astronomical amount of manpower and material resources.

It is impossible for the general contracting company to directly determine that there is a BOSS lair in the other world in which they are located, after all, this is a fairly small probability event, and at the moment, even if the new star company finds the BOSS lair, it seems that the gains outweigh the losses, if you count the rescue fee of 200,000 yuan per person to be paid for this rescue, it is even more of a loss that there are no underwear.

···

Li Fei led the way in front of him quickly, and he ran for nearly half an hour, and indeed he didn't meet a single zombie on the way - not only that, but not even the bats, maggots, spiders and other creatures that would wander in the cave day and night could not be seen, which was very evil.

The rescue team, which was quite neat when it first set off, was also turned into a sparse evacuation queue by nearly half an hour of rushing through the cave, and the air in the cave became more and more stuffy.

Now there are only a few dozen people who can still keep up with Li Fei and not fall behind, these people are almost all evolutionaries with a certain level foundation, and the equipment on their bodies is quite sophisticated, Xu Ping'an looked at it slightly, there is no figure of Ding Zhaohui among them - Ding Zhaohui is a warrior with a good physique, and it must be no problem to follow the front, if he doesn't appear, nine times out of ten he will be by Lin Quan's side.

"How far is it? It's hundreds of meters underground..."

Xu Ping'an felt that his snort was getting heavier and heavier, and his naked upper body was also covered with sweat - the deeper he went underground, the hotter the temperature became, and now the line was getting longer and longer, which was really a dangerous behavior.

"Wait, be careful ahead. ”

At this time, Li Fei, who had been anxious and had not slowed down at all on the road, suddenly began to slow down, and said to Xu Ping'an and the other adventurers who were following him.

Now those who can still be in the first echelon are not idiots, so they naturally slow down with Li Fei.

"Is this the smell of zombies?"

Xu Ping'an smelled the hot air, and wisps of rotting and fishy smell seemed to begin to appear, just like the smell when the zombie tide appeared, and the further he went, the stronger the smell became.

Li Fei, who led the way, changed his speed from running to walking.

"Dididi-"

After walking a few steps forward, suddenly, Xu Ping'an heard a subtle prompt sound in his ears, and on the lens in front of him, a bright spot and azimuth distance prompt were suddenly refreshed.

"Detective tracker detected?!"

Xu Ping'an frowned slightly, and the data on the lens showed that the prisoner tracker was 30 meters ahead!

Xu Ping'an's gaze crossed Li Fei's figure and looked at the ground in front of him, only to see a few pieces of armor fragments and torn bloody cloth scattered on the ground, as well as the remains of several zombies.

"There are traces of battles here!"

Xu Ping'an suddenly quickened his pace, overtook Li Fei, rushed to the front, bent down and picked up a palm-sized blood-stained rag from the ground, and pointed at a zombie body on the ground with a knife and said.

"Be careful, a little further ahead, it's the Corpse King's Palace! The traces of the battle here were left behind when I rushed out..."

Li Fei saw Xu Ping'an rushing past him, and he also hurriedly shouted, and saw that Xu Ping'an just picked up a rag from the ground and did not continue to rush forward, so he breathed a sigh of relief.

"It had to be a tough battle. ”

Xu Ping'an moved his fingers slightly, retrieved his "prisoner tracker" from the rags, and pretended to investigate Li Fei's final battle scene, nodded and said.

This is not a lie, although Xu Ping'an's "Prisoner Tracking Glasses" and "Prisoner Tracker" are from another world, they are also "technological side equipment" that are incompatible with the other world of Luoxia Island, and they can still maintain a contact range of hundreds of meters on the ground before, but now when they are approaching the boss's lair, the contact range is compressed to thirty meters, which can be regarded as proving the strength of the supernatural elements here, indicating that there is a more deadly danger.

"Let's just wait here, let the evolutionaries equipped with flamethrowers and the ability to damage a large area gather first, the passage in front of you will go to the end, and then turn a corner, it will lead to the cave of the Corpse King's Palace, but it will be a little difficult to enter..."

Li Fei had always looked anxious when he led the way, but now that he was really approaching the destination of the rescue, he began to calm down - or began to feel a little scared?

After stopping, the extremely long scattered team finally began to rearrange and gather, taking advantage of the whole team, Xu Ping'an and a few other adventurers who had been rushing to the front cautiously groped in front of the tunnel, wanting to see what the situation of the boss lair "Corpse King Palace" in this different world was.

What is this sound?

After walking a distance, Xu Ping'an could already hear some sounds in front of him, and there was indeed the sound of battle - but this sound was still relatively far away, and the clearest and loudest was a strange "rustling" sound.

Xu Ping'an turned his head slightly and looked at the expressions of several evolutionaries around him, they obviously heard it too, and their faces were a little strange.

Soon, Xu Ping'an and the others touched the end of the passage, looked out carefully, and couldn't help but widen their eyes.

At the end of this passage is an underground karst cave that resembles a huge basin, covering an area of several football fields, and the bottom of the cave is full of huge black stalagmites that can only be hugged by several people, and the surface of these black stalagmites seems to have a faint layer of metal reflection.

"Black iron ore!"

Xu Ping'an just glanced at it, and he could see that the material of these huge stalagmites was very similar to the hottest "black iron ore" in the other world of Luoxia Island, and it was also a higher purity kind!

If you measure it according to the value of a gram of black iron ore more expensive than gold on the current blue star, then the wealth brought by a huge black iron stalagmite is enough to make people crazy, not to mention that this cave is full of such huge black iron stalagmites...

But that's not the point, the point is... The entire underground cave is full of dense, thousands of zombies, almost rubbing shoulders!

The clear and loud "rustling sound" that Xu Ping'an heard before was the sound of countless zombies on the field moving step by step!

"This, this is the Corpse King Palace?!"
