Douluo starts with the Pea Shooter

There is no powerful existence on the first floor of the underground world. The one guarding the entrance to the first floor is the fire giant. This is the most ironic thing. The most surviving beings on the first floor are the fire spirits. But because they are too weak, they can only survive as slaves. As for the guards on their own floor, they are not from their clan.

The fire giant is not very strong. It barely reaches the ninth level. In the human world, this strength is indeed very strong, but there are many races in the underground world, and humans only have one race. Obviously, it is impossible to compare with the underground world in terms of the number of strong people.

The fire giant is huge. Standing there, it almost blocks the entrance to the lower level. For these fire-attributed creatures in the underground world, the closer to the center of the earth, the more suitable it is for cultivation. In contrast, although the area closer to the surface 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. There are hollow layers inside, and there is no magma. In a sense, this also makes the interior of this planet relatively fragile. If it is hit by any external force, it is likely to collapse on a large scale.

Before challenging the guards of the first layer, Lan Nuo observed the terrain of this layer. This unscientific planetary structure is not likely to be formed naturally by the planet. Otherwise, such a structure may collapse in a few tens of thousands of years under natural conditions.

In order to verify his conjecture, Lan Nuo caught a red fire spirit on this layer. Although they are weak and can only exist as slaves in the underground world, their IQ is not much of a problem. They have an IQ similar to that of normal humans.

This is also the advantage of the underground race over most monsters. Although they are also suffering, their IQ is much higher than that of ordinary beasts. In this way, they can practice more independently and their strength is also stronger than the existence of monsters at the same level.

"Why do you have to go through the entrance to get to the lower level? Can't you try to dig directly underground?"

The fire spirit he caught thought that his life was in danger. He was too scared to speak at first. He dared to answer after being comforted for a long time.

"It is impossible to dig down. Although the underground world is hollow, there is extremely thick earth between each layer. Even if we spend our lifetime, it is impossible to dig through."

"Has no one tried it? Even if one generation can't dig through, generations will be able to dig a passage sooner or later.

By then, the underground passages will be connected in all directions. Who can guard them all? Even if someone has a hand to the entrance, they can dig a tunnel and go around the entrance to go down. This operation is carried out year after year. After all, there is no way to isolate the different levels.

Has no one among you tried this kind of thing? If the underground world is really so attractive to you, there should be no one who has tried it."

The fire spirit saw that the person he was facing seemed to be a person who was easier to talk to, and his courage gradually grew, so he solved the problem. Shi said: "Legend has it that someone did try to dig through the strata, but they all failed in the end. It is said that if you dig down for dozens of miles, you will encounter an extremely solid structure.

If it is normal soil and rock, we can still dig through it bit by bit, but we can hardly destroy the things in that layer. Even the strongest of the fifth level of our race can only make a small pit on it with the power attack.

And that layer of extremely hard structure seems to cover the entire circle. If you want to break through it, it will probably take hundreds of thousands of years. This is too difficult. Our race has never had such a long time in history. It is almost impossible to penetrate."

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

There should be an extremely solid man-made layer between different levels. This man-made object not only blocks the shuttle between the levels, but also supports the structural skeleton of the planet. If there is no such skeleton, this planet with a lot of hollow inside will probably collapse soon because it cannot bear its own gravity.

The fire spirit just now seemed to be addicted, and continued to talk about the great achievements of his ancestors: "In fact, our predecessors have not only tried to dig through the ground.

Because they could not bear the miserable oppression of being treated as slaves, they also tried to perish with the entire underground world.

At that time, they chose to dig up all the supports on the ground. As long as these pillars supporting the surface were dug up, the earth would fall from the sky and hit our layer. In theory, it would be enough to destroy the supports of the next layer. In this way, layer by layer, gradually destroying, the entire underground world can be destroyed.

However, they failed in the end. When they dug those pillars supporting the sky, they also found that kind of indestructible structure inside. Our most powerful attack could only produce extremely small scars on it. I am afraid that even the real strong men in the underground world would find it difficult to destroy a pillar at one time with their all-out attack."

Lan Nuo nodded and said that he already understood the situation. The situation on this planet was far more complicated than what was described in the original work. Perhaps there were existences like prehistoric civilizations that built extremely large facilities underground on the planet. And because of the long period of time, the facilities they built were buried in the soil, leaving only the original features of the underground world.

As time goes by, it gradually becomes desolate and is occupied by underground creatures. It is even very likely that the energy that releases heat deep in the core of the planet is not the core at all, but some other powerful existence.

Before heading to the second floor, Lan Nuo first searched for the cave leading to the underground.

Master Cat didn't go with him. Originally, he wanted to go to the underground world and visit this other world. However, the people living in this world are not human beings. Except for the weakest fire spirits, for him This human being is quite repulsive. In addition, the superficial circle is full of strange creatures. It is impossible for beautiful women to appear. Master Mao's mind gradually becomes dull.

But if I have to say it, 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 earth's core. Lotus is a race of flames and a powerful creature deep in 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 beautiful.

Otherwise, it is impossible for the future protagonist to become a couple with Lie Yan. Imagine the Flame Queen deep in 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 underground. Although no one had maintained the cave for a long time, he still kept it. has not been filled in.

After all, it took a lot of effort to dig this cave. If you want to fill it back, it will also consume a lot of resources. In this world of the jungle, no one wants to waste. Now that this is known, there is no way this cave threatens the levels below. Naturally, there is no need to care about him.

A cave leading to the ground. Although it has not been filled in, it has been in disrepair and has been severely damaged. Many sections of the road have completely collapsed and blocked.

It can be seen that this cave was originally built. There is still a certain strategy, the cave is not straight up and down, but a diagonal downwards.

Even if you keep walking down, the angle of inclination remains the same from a somatosensory point of view. This shows that the person who dug this cave has certain mathematical knowledge, or has used a level or other equipment to measure the excavation during the excavation process. Angle.

As we all know, the planet is spherical. If you dig along a straight line, the angle with the horizontal plane will become smaller and smaller. If the calculation error is relatively large, you may even dig higher and higher.

Therefore, if the underground cave in front of you is cut open 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 didn't go very far when he encountered a cave-in. The cave was blocked by the earth and rocks that collapsed from above. However, this was obviously not a problem. Lan Nuo showed his earth attribute ability. Although this ability It is not his strongest attribute, but as one of the six basic attributes, it still barely reaches the level of the ultimate attribute.

Under his control, the rocks were suspended, and then solidified together, as if they were fixed like cement. The surrounding areas of the collapsed cave were re-reinforced, and further down there was another passable cave.

However, at this position, there is very little breathable air. Fortunately, both of them do not need to breathe and can survive for a long time.

Slowly going down and cleaning up, this cave has been abandoned for who knows how many years. After walking for probably thousands of miles, I finally reached the end of this cave.

This place has been buried by soil, but after cleaning it up, you can still barely see the original appearance of the cave. The collapse here and other locations outside are due to disrepair, and it looks more like the situation that appeared after some violent explosion. .

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

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

I guess the people who were blocked from digging here must have been unwilling to do so, so they found explosives to see if they could blow up the hard layer underground. In the end, the cave collapsed, and I also It was buried underneath, and no one in future generations would try this behavior again.

This ending is really disappointing. After collecting these bones and preparing them 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. Not only that, the end of the cave actually covers a large area.

The person who dug here probably thought that he had encountered a hard rock at first, so he planned to bypass the rock. However, he dug in all directions, only to find that there was no room for bypassing, so he finally chose to try violent destruction.

The area of ​​​​this underground space is almost as large as a small town, and the furthest passage extending out is hundreds of miles away. It can be seen how determined the people who dug here are.

Lan Nuo did not clear out all these tunnels. Since someone has already tried to dig them, it can basically be proved that this hard structure that looks like metal underground should be a huge whole. There is no way to get around the obstruction of this thing by taking a detour. It is very likely that you will eventually choose to take a detour and dig all the way to the original entrance to the underground.

There is no point in going around there, after all, the entrance is guarded.

Lan Nuo touched these metal-like substances on the surface, and then sampled some from them. Although this thing is hard, even Titled Douluo-level attacks cannot cause much damage, but in front of the Demon God Pillar and the artifact, they are still not hard enough, and they can relatively easily cancel the sample from it.

Lanno carries a series of mechanical equipment with him that can analyze this layer of metal-like material.

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

"Using this kind of thing to blockade is to restrain the power of the five elements on this planet?" Lan Nuo thought briefly and guessed the possibility of establishing this layer of blockade. The power of the five elements in this world can be easily controlled. Different materials, if it is only blocked by metal, then the strong metal can break the blockade quite easily. If it is blocked by rocks such as concrete, it will be like what Lan Nuo showed before. In that way, an underground tunnel can be easily dug, and there is only a structure like a living thing, and various attributes cannot be controlled.
