Underground world, area r.

No matter how many times I imagined what the underground world should look like, when I saw it, I realized that human imagination is still full of limitations and cannot fully outline another civilization.

At least Tang Ling thinks so.

What kind of civilization should this be? In fact, when jumping down from the edge of the uneven crack and shuttled underground, you can give a superficial definition, called the "cave" civilization?

Yes, it seems that this underground race has a persistent pursuit of holes, so the underground is not the kind of deep ravines that imagine that they can directly lead to the R area, but the winding and chaotic caves.

The underground black market should like this place.

Because these underground races not only have persistent pursuit of hole digging, but also should be masters.

The caves they create are neat and ventilated and smooth. I don’t even know what techniques they use. Each cave has a light-transmitting mouth, which brings natural light from the ground in a twists and turns.

Although in Tang Ling's opinion, this is a problem that can be solved by just a luminous body, such as oil lamps, after all, underground races should not lack oil, right? But they are still not afraid of trouble to attract natural light. Can we understand that this is a kind of persistence?

In addition, they may not be able to control their hands and occasionally carve some decorations that are difficult for humans to understand on these caves that serve as passages.

Perhaps it is decoration? It may also be their totems and words, which seem to tell an ancient history.

Because of the existence of the 'sense body', all these caves are strange 'double circle' structures, just a small circle next to a large circle.

You can imagine a scene where when the prosthetic body is removed, they will walk in small caves, and when the prosthetic body is equipped, they will walk in large caves.

However, according to human thinking, you will think that this is a waste of engineering, so wouldn’t it be better to directly build it into large caves?

Therefore, seeing this strange and strange shape of double circles adjacent to each other and intersecting each other, making the road more complicated, Tang Ling could only think that these underground races had special persistence in digging holes.

After a century of exploration, these maze-like roads can no longer become obstacles to progress. According to the special marks left by human beings, they move forward almost without any obstacles.

Tang Ling's accurate instinct was running quickly at this time, and such a complex road was quickly imprinted in his mind, like an accurate 3D model.

After all, the only topographic map is Andrew, and Tang Ling is unwilling to be controlled by others at this point.

The cave is very quiet and there is no underground race. According to Alber's intelligence, after all, the large army is gathering, and the possibility of meeting the underground race here is zero.

Just walking through it makes people hope to see what the civilization of underground races looks like?

"I can't see it. Even if I go to R, it's not their true civilization." Andrew's voice came from the front of the team. He was answering a question from someone in the peak team before. R was clearly the residence of the underground race. Why did Yangkong say that no one knew the real underground civilization?

"Why?" Someone couldn't help asking, his voice was slightly high, echoing back and forth in the quiet cave, and I don't know how far it was.

"Quiet." Andrew scolded in a low voice, but replied simply: "It is said that the true civilizations of underground races gathered in their underground cities. That is the origin of their civilization, and there are secrets about this planet."

"As for the R area, or even larger underground race gathering places, it is impossible to see their civilization. You can understand that it is just a military camp, a military camp that invades the ground. Can you see their civilization from a military camp?"

I have to say that Andrew's knowledge is rich, and these things that cannot be found in the database have further deepened Tang Ling's understanding of this world.

"I'm really curious about their city." Someone couldn't help but whisper.

"It's better not to have such thoughts. Everything is as Master Yangkong said. No one has ever really entered their country, let alone those big cities. There are more powerful humans than you think, so why is this still happening?" Andrew used a rhetorical question to dispel the person's unrealistic curiosity.

And why? Humans have always been creatures with endless desire to explore and full of curiosity. This seems to be an instinct engraved in genetic fragments. However, driven by this instinct, they still know almost nothing about underground civilization, which only shows that the danger there is unimaginable, allowing countless strong people to go but not return.

Even so, it is good to be able to take a look at the R area. Even if a place similar to a military camp cannot see their civilization, at least it can outline some clues.

This is Tang Ling's idea, and it is also the idea of ​​most Crescent Warriors in the First Preparatory Battalion.

Only geniuses have this mood. Before the battle of life and death, they were full of curiosity full of doubts.

But this was a marching after all. After this problem, the team fell into silence again, with only extremely fast footsteps resounding in the cave.

According to the marching speed of the First Preparatory Battalion, the winding cave also allowed them to move forward for 15 minutes before reaching their destination - R.

Tang Ling used precise instinct to calculate all the way. These caves seemed to be parallel, but in fact they were winding down the road. However, the downward angle was very slight, which seemed to be only 50 meters deep from the ground, but in fact they had already penetrated underground to a vertical height of nearly a hundred meters.

Here, you can't feel any difference from the ground. There is still air circulation, not stuffy, and there is still natural light entering. But in addition, the entire R area is filled with strange high temperatures.

Sixty-two degrees.

This is the answer given by precise instinct.

If the humans of the former civilization were in such an environment, they could not last for an hour.

Because this place is not an extremely dry environment, but an underground river is twisting and turns through the center of the entire R area, which is doomed to be filled with humidity, which will cause human sweat to fail to evaporate smoothly.

But in this era, such an environment and high temperature are not unbearable for ordinary people, or the time it can bear is greatly extended, let alone these crescent warriors who have far surpassed ordinary people.

Apart from a little bit of heat, they did not feel any discomfort, and they did not even have the idea of ​​unbuttoning conventional combat uniforms. Now they are shocked by this brand new civilization, even though this is just a so-called military camp.

Tang Ling was also shocked.

He found that it was wrong to define this civilization as ‘cave civilization’ before. If it was really necessary to define it accurately, it should be ‘geothermal civilization’.

What is the entire R area? It is a huge cave, but in this cave, in addition to an underground river, there is also a lava cave with a diameter of no more than 10 meters and is constantly boiling with magma, just like the entrance of a crater.

The hole is not exposed, but a translucent cover like an impure diamond covering it.

There are extremely complex patterns on this cover, just like patterns on a gene chain calculator, but it may be much rougher than that. After all, the patterns on a gene chain calculator are so fine that you look like an ordinary line, but there are countless lines in the lines.

But even so, Tang Ling used precise instinct observation and found that its fineness was no less than that of the most advanced chips of human beings, but the circuit composition was a completely different structure, with red fine gems inlaid on key points, just like the high-end mechanical watches of humans using artificial rubies as mechanical bearings.

But Tang Ling had no idea whether these fine rubies were bearings.

I only know that this diamond cover is also perfectly qualified for the use of exquisite abstract artwork.

But no one could take it away because it was obviously a large instrument with a solid pipe on it, with a diameter of about twenty centimeters and three meters long.

These three-meter solid pipes were polished very brightly and neatly, and multiple tiles were carved from different angles, just like humans carved diamonds.

I don’t know what principle this cover uses to gather heat energy from the magma, making the entire solid pipeline red, like a pillar of fire.

The fire pillar is connected to a diamond cover at one end and a machine hanging from a height of three meters at the other end.

The whole body of this machine is also covered by diamonds, but you can blur the various parts inside, just like gears and bearings running constantly.

On this machine, there are countless pipes connecting it. These pipes are firmly fixed to the top of the hole, and then they spread out countless branches, leading to various small holes on the hole wall.

These small caves are obviously caves inhabited by underground races. Even if they stand in the center of the hall, they can feel the circulating air and wind, the constant temperature, and... Some ferocious essays are hung outside the small cave, directly connecting to a pipe, flashing brightly and extinguishingly.

So? These pipes have the function of "air conditioning" to keep the temperature here at 62 degrees that underground races like? At least after Tang Ling entered the R area, he found that the temperature here was almost constant.

These pipes also have the function of a ‘fresh air system’ that exchanges air and allows air to flow?

The biggest function of these pipes is to recharge the prosthesis?

Tang Ling can't guess specifically what he has. After all, he is not a technician, but in general, Tang Ling knows where the energy support of underground civilization comes from, from these magma! Or various geothermal heat.

There is no doubt that as long as there is sustainable energy, a civilization will have a foundation for development.

Even Tang Ling is a little a little sour. After all, their energy seems to be more environmentally friendly and more environmentally friendly than the oil energy used by humans in the previous civilizations...

They even used their racial advantages to mine diamonds in large quantities... The previous civilization had speculated that the planet's diamond energy was actually very rich, but the previous civilization's technology could not mine these deep-buried diamonds.

Therefore, according to the hardness of diamond, it is indeed long-lasting, but its value is probably not enough to be passed down forever.

In short, it is such a power equipment that uses geothermal heat that has refreshed Tang Ling's understanding of underground races, but this does not represent the entire underground race.

Because it is full of a very strange sense of contradiction.

There is clearly such advanced geothermal technology, but there are fires everywhere here, and there are all kinds of gnawed bones piled up next to the fire, and there are even bones in them.

This is a very angering thing. It is not the same race, and the underground race will not have any psychological burden to eat people, but humans can never accept this fact when they see it.

Such a primitive and rude way, coupled with the pottery, bone utensils, and even stone tools that were excavated from ancient civilizations, which were even rougher than those of ancient civilizations, make people suddenly feel that they have seen the primitive society.

What kind of collision is this? Tang Ling's eyes couldn't help but fall on the small caves that seemed a little densely packed on the walls of this huge cave.

These caves are not as rough as they think. They have different shapes and although their lines are weird, they seem very rich. Each cave thinks of an abstract sculpture, where you can find a little shadow of human civilization.

For example, when Tang Ling saw one of the caves, he was full of the atmosphere of ancient China, and tried hard to express the ancient style of tiles, bricks and stones, and the quiet and elegant feeling surrounded by green bamboos.

Although you are not learning well, it seems a bit inappropriate when combined.

Is this the "spiritual world" of underground races? Everyone is a carving and hole-punching master. Perhaps life without sunshine is too depressing, forcing them into this way? After all, there are also people playing with mud and stones underground.

Tang Ling had no sympathy in her heart. Why did she sympathize with these cannibal guys? She didn’t even have the interest to use civilization to integrate them!

The only thing that can be done is to maintain proper humility and respect for a brand new civilization.

After standing here for only two minutes, Tang Ling got this information and finally had a shallow understanding of the underground race.

But the mission here is to fight.

Andrew also coughed appropriately, and then said, "Standing here to satisfy your curiosity is the most failed thing for me as a commander. Fortunately, no battle happened."

"Now, let's disperse each other and start the task according to the previous arrangement."

**

The area where the Raptors are located is at an interlaced point in the second and third strategic roads.

The radius of this place is about one mile and close to the underground river. Because the shape of the large caves in the entire R area is not only irregular, but also very distorted, there is a rock wall extending from the north and south sides of the place that covers it, like a semi-confined small area.

Apart from that, nothing special here.

After the Raptors came here, they each began to rest on the spot. After all, it seems quiet now, but the battle may happen at any time, so keeping the physical strength in the best condition is something that a qualified warrior cannot forget at any time.

But Tang Ling did not choose to rest at this time, but walked around this radius of one mile.

He was observing everything here and gradually frowned.

These two rock walls look very secure. In addition to receiving support signals, it is a bit troublesome to bypass the rock wall and go out to fight.
