Chapter 451 Prehistoric Cave
There are no powerful existences on the first floor of the underground world. The entrance to the first floor of the handle is the flame giant. This is also the most ironic. The existence with the largest number of survivors on the first floor is the fire spirit.But because they are too weak, they can only survive as slaves.As for the guards at my level, none of them belonged to their clan.

The flame giant is not very strong, and barely reached the ninth level. In the human world, this strength is indeed very strong, but there are many races in the underground world, but humans have only one race. Obviously, it is impossible to increase the number of strong people. compared to the underground world.

The size of the fire giant is huge, and standing there almost blocks the entrance to the lower floor. For these fire-attribute creatures in the underground world, the closer to the center of the earth, the more suitable for cultivation. In contrast, those closer to the surface Although the area has a larger area, it is not precious. All underground creatures prefer to live closer to the center of the earth.

The temperature there is higher, and they can practice faster. The structure of this planet is obviously quite different from other rocky planets. The interior is one hollow layer after another, and there is no magma. In a sense, this also makes the interior of the planet relatively fragile, and if it is hit by any external force, it is likely to collapse on a large scale.

Before challenging the guards on the first floor, Lan Nuo observed the topography of this floor. This unscientific planetary structure does not seem to be a natural formation of the planet. Otherwise, such a structure may last tens of thousands of years in a natural environment. It collapsed.

In order to verify his conjecture, Lan Nuo caught a red fire spirit on this floor. Although they are weak and can only exist as slaves in the underground world, there is actually no big problem with their IQ. They are different from normal human beings. have similar IQs.

This is also the advantage of the underground race compared to most monsters. Although they are also affected, their IQ is much higher than that of ordinary beasts. The presence of classes is much more powerful.

"You go to the lower level, why do you have to go through the entrance? Can't you try to dig directly into the ground?"

The Huo Jing who was caught by him thought that his life was in danger. At first, he was too scared to speak, but he dared to answer after being comforted for a long time.

"Digging down is absolutely impossible. Although the underground world is hollow, there is an extremely thick ground between each layer. The distance is hundreds of miles. Even if it takes us all our lives, it is impossible to dig It works."

"Has no one tried it? Even if it is a generation of people, if they can't dig it, they will be able to dig a tunnel sooner or later.

At that time, the underground passages will extend in all directions, who can guard them all?Even if someone says that the entrance can also dig a tunnel, bypass the entrance and go down, and carry out this kind of operation year after year, after all, there is no way to carry out such isolation between different levels.

Hasn't any of you tried this kind of thing?If the underground world is really so attractive to you, no one should have tried it. "

Huo Jing saw that the person he was facing seemed to be a relatively easy-to-talk existence, and gradually became more courageous, so he explained: "It is said that some people did try to dig through the ground, but they all failed in the end. Digging for dozens of miles, you will come across an extremely solid structure.

If it is normal soil and rocks, we can still dig through a little bit, but we can hardly destroy the things on that layer. Even the strongest of the five levels of our race can only use power attacks on it. A small pit.

And that layer of extremely hard structure seems to cover the entire circle, if you want to break through him, it may take 10 years.It's just so tough, it's been so long in the history of our race, it's almost impossible to penetrate. "

Lan Nuo couldn't help showing a strange look on his face when he heard the words. He had always been curious about why there were only a few people guarding the entrance between the various circles, so there was no way to penetrate each other. Now it seems that the reason has been found.

Between different levels, there should be a layer of extremely strong artificial objects. This artificial object not only blocks the shuttle between the layers, but also supports the structural skeleton of the planet. If there is no such layer of skeleton, the interior A large number of hollow planets may collapse because their own gravity cannot bear it in a short time.

And the Huo Jing just now seemed to be addicted, and continued to talk about the great achievements of his ancestors: "Actually, our predecessors have not only tried to dig through the ground.

Because they couldn't bear the miserable oppression of being treated like slaves, they even tried to die with the entire underground world.

At that time, they chose to support the ground and cut off all the pillars. As long as these pillars supporting the ground are broken, the earth will fall from the sky and hit our layer, which is theoretically enough to wipe out the ground. The support of one layer is also destroyed, so that layer by layer, gradually destroyed, can destroy the entire underground world.

However, they also failed in the end. When they excavated the pillars supporting the sky, they also found that kind of indestructible structure inside. Our most powerful attack can only produce extremely small scars on it, I'm afraid Even for those real strong men in the underground world, it is difficult to destroy one pillar at a time with an all-out attack. "

Lan Nuo nodded, indicating that he already understood the situation, and the situation on this planet was far more complicated than described in the original book.Perhaps there are prehistoric civilizations that built extremely large facilities underground on the planet, and because of the long time, the facilities they built were buried in the mud, leaving only the original features of the underground world.

With the passage of time, it gradually became deserted and was occupied by underground creatures. It is even very possible that the energy source of heat released from the depths of the planet's core is not the core at all, but some other powerful existence.

Before going to the second floor, Lan Nuo searched for the cave leading to the ground.

Master Cat didn’t go with him either. Originally, he wanted to go to the underground world to wander around this other world. However, the people living in this world are not human beings. The human beings are quite repulsive, plus the shallow circles are all weird-shaped creatures, there is no possibility of beautiful women or anything, and Master Cat's thoughts gradually fade away.

But if I have to say, the underground world is not without beauties. Although the races here are not born in human form, there are some who can transform into humans when they grow to a certain stage, that is, the flame red deep in the center of the earth. Lian, that is the race of flames, and a powerful creature deep in the heart of the earth. They are usually in the form of lotus flowers. After they grow to a certain stage, they will transform into humans, and all the girls are online.

Otherwise, it is impossible for the future protagonist to become a couple with Lie Yan. Imagine the Flame Queen deep in the heart of the earth. If she looks like the Goblin Queen, is it possible for the protagonist to fall in love with her?
……

Under the guidance of the world's weakest fire spirit, the two successfully found the cave leading to the ground. Although no one has maintained this cave for a long time, he still keeps it.is not filled.

After all, it took a lot of effort to dig this cave.Wanting to fill it back also consumes a lot of resources.In this world of the jungle, no one wants to waste.Now that it is known, it is impossible for this cave to threaten the layers below.Naturally, there is no need to worry about him.

Cave leading to the ground.Although it has not been filled, it has been in disrepair for a long time and has been damaged quite seriously. Many road sections have completely collapsed and blocked.

It can be seen that the cave was built in the first place.There is still a certain strategy, the cave is not straight up and down, but a slanted downward.

Even walking down continuously, the angle of inclination remains the same in terms of somatosensory, which shows that the person who excavated this cave has certain mathematical knowledge, or used equipment such as a level to measure the depth of the excavation during the excavation process. Angle.

As we all know, the planet is spherical. If a straight line is excavated, the angle between the horizontal plane and the horizontal plane will become smaller and smaller. If the calculation error is relatively large, it may even appear that the digging becomes higher and higher.

Therefore, if the underground cave in front of you is cut and viewed from the side, it is actually closer to a spiral downward structure than an oblique downward structure.

Lan Nuo walked into it, and within a short distance, he encountered a collapse. The cave was blocked by earth and rocks that had collapsed from above, but this was obviously not a problem. Lan Nuo showed his earth attribute ability, although this ability It wasn't his strongest attribute, but as one of the six basic attributes, it barely reached the level of the ultimate attribute.

Under his control, the rocks were suspended, and then hardened together, fixed like cement. Around the collapsed cave, the cave was re-reinforced, and the cave was accessible again downwards.

But at this position, there is very little air to breathe. Fortunately, both of them don't need to breathe, and they can survive for a long time.

Slowly clearing down a little bit, this cave has been abandoned for an unknown number of years. After walking thousands of miles, it finally came to the end of this cave.

This place has been buried by mud, but after cleaning it out, you can still barely see the original appearance of the cave. The other places outside the collapse here are due to disrepair for a long time, and it looks more like it appeared after a violent explosion. .

In the process of cleaning up these wreckages, Lan Nuo found some white bones buried here. Judging from the shape of these bones, they should be the fire spirits above.

From the residue of the soil, some explosives that once existed here can still be barely distinguished.

Thinking back, the people who were blocked when they dug here must have been very unwilling, so they found explosives and wanted to see if they could explode the hard layer of the ground, which eventually caused the cave to collapse, and they themselves After being buried below, no one in future generations will try this behavior again.

Such an ending is really embarrassing. After collecting these bones again and preparing to take them out for burial, Lan Nuo finally cleared the final tunnel.

A metallic structure can be seen at the end of the tunnel.There are many scratches on the surface of this structure, and more than that, the end of the cave actually occupies a large area.

The people who dug here probably thought they had encountered a hard rock at first, so they planned to bypass the rock, but they dug in all directions, but found that there was no room for bypassing, so they finally chose to try violent destruction.

And the area of ​​this underground space is almost as big as a small town, and the furthest passage stretches over hundreds of miles. It can be seen how determined the people who dug here are.

Lan Nuo didn't clear out all these tunnels. Since someone has already tried to dig them out, it can basically prove that the underground hard structure that looks like metal should be a huge whole.It is not possible to bypass the barrier of this thing through a detour. It is very likely that you will choose a detour in the end and will dig all the way to the original entrance to the ground.

And it doesn't make any sense to go around there, after all, that entrance is guarded.

Lan Nuo touched these metal-like substances on the surface, and then took a sample from above.Although this thing is hard, even a Title Douluo level attack can't cause much damage, but they are still not hard enough in front of the Demon God Pillar and the artifact, and the samples can be removed from it relatively easily.

Lan Nuo carried a series of mechanical equipment with him, which could analyze this layer of metal-like substance.

The conclusion drawn after the analysis is a bit weird. This thing is not a metal, but a special high-strength compound. The most important thing is that this thing is alive, and it is a kind of metal-like life form. Maybe they They used to be nanomachines, but now they are an independent species that can survive without external interference, but their own movement ability is very poor, and they may not be able to move a distance of one millimeter for thousands of years.

"Blocking with this kind of thing is to restrain the power of the five elements on this planet?" After a short thought, Lan Nuo guessed the possibility of establishing this layer of blockade. The power of the five elements in this world can be easily manipulated Different substances, if only metal is used to block, then the strong metal can break the block quite easily. If concrete and other rocks are used to block, it is just like what Lan Nuo showed before. In that way, an underground tunnel can be easily dug, and there is only a structure like a creature, and various attributes cannot be manipulated.
