Crawling the Underground World?

When everyone saw those six big characters, they were all a little dumbfounded. Pen "Fun" Pavilion www.biquge.info

Looking at such a huge underground space in front of them, everyone already roughly understood the meaning of these six words.

Wang Ruyi muttered: "It turns out that I didn't guess wrong, this is really the world of reptiles, but this is too weird, the world of reptiles actually exists in the underground karst cave." ”

Xue Erliu couldn't help but exclaim: "This karst cave is really an underground miracle, I didn't expect its cave to be so huge, the cave will be so magical, if everything in this cave is exposed, I don't know what kind of monstrous waves will be set off?"

The words of the two made many hunters and agents feel the same way.

This underground cave is so big that they have never heard of such a huge underground cave.

It's a few hundred meters high, and you can't see the end at a glance, but how many kilometers long it has to be, right?

Underground karst caves with a height of several hundred meters are common, but almost all of them are so high that it is too rare.

The roof of the cave is dotted with lamps that emit sunlight similar to daylight.

The lamps emitted a soft glow, so much so that people could see almost everything inside the cave without relying on a flashlight.

Perhaps they were the only ones standing near the cave door now, because it was a little sunken inward, so the lights on the roof of the cave didn't shine much on the door.

In addition, the position they were in now was not too high, and there were two high ground in front of them blocking their view.

A track similar to an outer cave winds its way between the two high grounds, so they can only see some of the arrangements at the top of the cave and some of the nearby conditions, but they can't see everything behind the high ground.

But that's enough, and it gives the strange feeling of standing in a dark cave and looking at the grand world outside.

I just feel that the position they are in at the moment is so small, and everything in the outside world is so huge.

But they don't know what kind of world they can see when they climb the hillside in front of them?

The nearby cave ground, including the small plateau in front of you, is obviously artificially arranged and arranged, and it is not a near-natural cave like the outer cave, its surface is covered with a thick layer of soil, and various plants grow on the soil.

Who would have thought that this would be a huge cave in the middle of a mountain without looking up at everything on the top of the cave?

Chen Lingxi looked at everything on the high ground not far away in surprise, and whispered to himself in disbelief: "These are all plants growing on the surface, how can they survive in the cave?"

Xu Qianyun used a telescope to look at the top of the cave three or four hundred meters high, and saw that in addition to the lamps and lanterns that emitted soft light, there were also some pipes and sprinkler arrangements on the top of the cave, and she immediately understood everything.

She explains: "They used special LED tubes, similar to those that emit sunlight, to create artificial sunlight, and then used water pipes and sprinklers to create artificial rainfall to simulate an underground artificial environment, and then planted various plants to use photosynthesis to produce oxygen for the behemoths to breathe." ”

"What kind of LED light can it simulate sunlight?" Wang Ruyi still didn't believe it.

Xu Qianyun nodded: "Of course you can, plants need blue-green light and red-orange light in the spectrum for photosynthesis, and the special LED light can simulate these two kinds of light well." ”

Song Junxing, who was on the side, added: "These LED lights have another function, it can provide enough light and warmth to reptiles." ”

Seeing that most of the people were a little puzzled, Song Junxing explained: "Reptiles are not homeothermic animals, they do not have a perfect heat preservation mechanism and self-regulating body temperature function, and energy is very easy to lose, so they must obtain heat from the outside world to regulate their body temperature."

Since this is an underground crawling world, there must be all kinds of reptiles living there, so they need enough light to illuminate, and the light and heat that an LED tube can provide are relatively low, but the roof of this cave is densely arranged with so many LED tubes, it can provide huge energy, and even create a feeling of small spring in the cave. ”

Then the people understood.

But I was even more amazed by the grand arrangement in front of me.

Xue Qizhen's face became extremely solemn, and he turned his head to look at Li Xun: "Li Xun, I think we have to reposition the strength of our enemy. ”

Song Junxing also nodded and said: "Elder Xue is right, the previous Song Yongzhen and the evil spirit plan seems to be just the tip of the iceberg, and now this giant spirit plan really shows the strength of our enemy."

Not only do they have huge financial support, but they have also experienced a long period of arrangement, and their plans are very careful and huge, otherwise, they would not have been able to build such a huge underground kingdom here in the short term, and it would be impossible to protect the secrets of this underground kingdom so well. ”

Li Xun nodded solemnly.

Xue Qizhen and Song Junxing said it well.

I was still feeling why Yang Jiushan could provide such a high wage, but let some workers only engage in the most basic and simple handling work.

This seemingly high salary is nothing compared to everything you see in the cave now!

How much financial support is needed to keep such a huge cave running?

In addition to financial support, how strong does the power behind it have to be?

Unthinkable, unimaginable!

Thinking so in his heart, Li Xun waved his hand and said, "Let's go, let's go to the front slope to find a vantage point and carefully observe everything in the cave, but now there are many dangers around, everyone should be careful." ”

So everyone extinguished the powerful flashlight one after another, cautiously followed Li Xun and the others, and walked towards the small slope not far ahead.

Li Xun didn't walk along the track anymore, and the track passed through the middle of the two small slopes, which always made people feel unusually deep and uneasy.

Here, everything needs to be done with care.

Slowly bent down, everyone went up the hill.

And when they saw everything in front of them completely, a low exclamation came out of the mouths of the people around them again.

This time, instead of being amazed by the magical plant world at the bottom of the cave, they were amazed by the animals they saw, large and small, of all kinds.

Sure enough, they are all reptiles.

Lizards, snakes, crocodiles, and even some turtles.

Although it is large and small, it is also relative.

For example, the smallest one should be a group of four or five meters long, lizard-like animals not far away, which are slightly smaller than the big geckos that Li Xun and the others encountered before.

But even these four or five meters long little lizards are already terrifying existences.

As for the larger creatures.

All eyes fell on the middle of the cavern, around a large circular fortress made of concrete.

On that fortress, a giant serpent hovered.

How big does it have to be?

Although it was not as huge as the dragon python that Li Xun and the others had encountered before, it was at least about forty meters.

The snake was grayish-black, its head was raised high and flattened, and it opened its mouth and spat out letters.

Through the binoculars, everyone could clearly see that the mouth of the giant serpent was as if it had been stained with ink, and it was pitch black.

Song Junxing saw this scene clearly, and couldn't help but shout: "Black Mamba snake, the deadliest poisonous cobra in the world, oh my God, it's so big!"

A calm person like Song Junxing finally changed color this time. (To be continued.) )
