Faced with the sudden situation, when Lu Fei wanted to pull the calf of the nail, it was too late, there was a turn in the hole, and the flashlight could not shine at the bottom, so he didn't know whether he was dead or alive.

Just when Lu Fei was weighing whether to jump into the hole to save the nail, the fat man didn't hesitate at all, and used the rope to wrap around his waist and said: "Brother bayonet, you are on it, I will go down to save people!"

After saying that, the fat man pulled out his saber and jumped into the hole, and in an instant he slipped without a shadow. At the moment of life and death, the fat man is not ambiguous at all!

The weight of the fat man's body seemed to roll faster in the hole, and after about half a minute, the rope suddenly stopped, and there was a vibration at the end of the rope, and then the fat man suddenly shouted deep below: "Pull the rope!"

With the holy dagger in his hand, Lu Fei's strength seemed to be much greater, he grabbed the rope and pulled it up hard, and soon the fat man appeared dragging the nail, and the nail was still kicking, obviously the corpse still didn't let go.

Lu Fei immediately took out his pistol and fired a few shots at the big head of the corpse fetus, and the corpse fetus screamed and let go, but after relenting, he immediately wanted to rush up again!

Lu Fei naturally wouldn't give such a monster a chance again, and fired a few shots in a row, and this time he rolled the freak into the hole!

Lu Fei took this opportunity to pull the fat man and the nail out of the hole!

The fat man's face was pale, and he gasped and said to the nail: "Did you see the nail, it seems that this ghost daughter-in-law still likes you a little more." ”

"Like a ghost, anyway, you saved me this time, let's settle it!"

Nail still had a lingering heart, because in the short minute he had been dragged into the hole, Nail thought it was about to hang up!

"I'm wondering if this fucking hole is the nest of the corpse, if so, let's just blow up these monsters with explosives so that they can be reincarnated as soon as possible. ”

The fat man asked.

"There shouldn't be any old nests that aren't old nests, and the corpses are not animals, where did the old nests come from, but this hole is really a little strange, let's go to Xia Lao and them first, and then discuss and see when everyone is together!"

After all, for the study of this mausoleum, Xia Mingyuan is obviously more professional!

After turning back, the team of nine people met again, got together, and told Xia Mingyuan about the corpse and the cave entrance!

Then the group rushed to the entrance of the cave, and pondered and studied for a while, during this period, the corpse fetus never appeared again, it seemed that Lu Fei and the others were already outnumbered, and then fled!

"Old Xia, if there is no other exit, or let's go into the cave and have a look, this cave should lead to something else!"

Zhou Xiongjian said.

Xia Mingyuan looked at the entrance of the cave and thought for a moment, then nodded and said, "There is only this way, but when you enter the cave, you must be careful, nails, or you come first, do you have the guts?"

"Old Xia, I'm fine, I'm not scared!"

Because the cave is ventilated, there is no need to worry about the problem of oxygen, but because there is a corpse, this time into the cave, it is natural to prepare weapons to prevent accidents!

He took out the rope and tied it to the fat man's waist while throwing it down the hole, and the nail climbed down first, and after a few minutes, he heard the sound of the nail responding, proving that the cave was safe!

When it was safe to do so, the others also slid down the cave one after another, and the tunnel was very rough and the stones went in and out, and these were all basalt rocks gushing out during volcanic eruptions, and there were a lot of bubbles on them, and the density of these stones was very unstable, some were hard like iron, and some were soft like tofu.

Lu Fei and the others went down one by one, and the fat man was the last to come down, and suddenly a bunch of people crowded at the end of the slope of the stone road above!

This narrow hole under the ice is inclined down, to the place where the turn below, it becomes erected and narrow, and then inside, the height of the cave seems to continue to increase, suddenly open, the space seems to become very large, but it is dark, with a flashlight, the group found that this row has reached the end here, to the front of the rapid contraction and narrowing, and finally there is only a stone gap in front of which can only be entered sideways, like an irregular sword mark, but also deeply pierced into the mountain rock.

"It's strange, it stands to reason that this cave should be a secret passage used by craftsmen to escape? Why did it suddenly become a crack for people?

Zhou Xiong was a little puzzled.

"If I'm not mistaken, I think this corridor may be using natural volcanic caves, volcanic caves are very common in the rock formations of volcanic areas, extending in all directions, the longest volcanic cave can reach thousands of kilometers in length, like a spider web dense underground, maybe this volcanic gap can lead all the way to the opposite mountain range, because of this, they can dig such a long secret passage, it turns out to use the passage set up in advance by nature. ”

"Isn't that why we have to get into this crack too? You're all right, I'm big enough to choke. ”

The fat man is very self-aware, and at the same time, the fat dragon also looked at his body and said that he was worried!

"There shouldn't be any need to worry about this, this kind of volcanic karst caves are all dendritic structures, and these holes should lead to larger crevices, which are called underground corridors in geology, and some underground corridors are very large, and they will even form their own unique ecosystems inside, and I believe that the gaps will definitely widen soon after entering, because this kind of geological destruction starts from the inside." ”

There is no way to retreat, there is only to move forward, along the way, it has always been the nail in front of the road, so the first to encounter danger is often the nail, this time, Lu Fei mainly said: "Then let's enter the crack first, I'll open the way!"

For Lu Fei's skills, everyone in the group is very clear, although they didn't see it with their own eyes, but judging from the table at the critical moment, everyone also knows that Lu Fei is very strong, so this time Lu Fei opened the way, and others also thought it was appropriate!

Feilong and Zhang Zhen expressed some worries, but in the end, Lu Fei still insisted on being at the forefront!

After resting for a while, reorganizing his equipment, Lu Fei took the lead and began to enter the seam.

It was pitch black inside, and the flashlight was useless, because the darkness was all-encompassing.

After entering the gap one by one, the group walked sideways like crabs, and there were no artificial traces of the cave wall of this place, and it was almost impossible to turn their heads inside, looking ahead, their eyes were full of traces of glazed flowers, and a large number of karst dropdrops of various colors covered all the rocks, and they were covered with crystalline transparent frost, evenly arranged like condensed water columns.

However, the beginning of the seam is very narrow, and as I walk, the seam gradually widens, and finally I can turn around and move forward.

It was pitch black inside the gap, but the surrounding glass and melted mica reflected the light of the flashlight, making the surrounding light produce a magical effect, and the large area of lava thorns, rope-like crust lava, and lava stalactites covered with volcanic debris made it dizzying, very beautiful.

As they continued to walk deeper, Lu Fei and the others gradually discovered some signs of human activity, some tools that had obvious patina, all of which were made of bronze!

After walking for nearly three hours, when I came to the underground corridor that Xia Mingyuan said, the passage was very wide!

Here, there are a lot of signs of artificial construction, and on the crack wall on one side, many simple steps have been hewn out, all the way up, this step is said to be a step, but in fact it is just some protruding stones!
