Chapter 86 The Border of the Underground World

After the blocked stones, there was still a long cave. Leviathan continued to swim down the cave. And now it is going down again, and at the same time, it has also added routes such as left to right, etc., this feeling is like...

roller coaster!

...what is a roller coaster?

No matter, in short, with the deepening of Leviathan, the water that was originally still began to flow slowly for some reason, and it became faster and faster. Because it was downstream, Leviathan became easier, but when At the back, Leviathan was almost pushed away by this current, and the slow current had turned into a rapid current.

And now this passage is just down, following the gravity and water flow, Leviathan rushes down quickly!

Slowly, Lin could see a dazzling light appeared below, and there was a very loud roar.

Lin asked Leviathan to get ready, and slowly opened the cracks in the wings on both sides of the body. When it was close to the light, she suddenly stretched her wings and opened the jets behind her!

'Boom! ' In this short moment, Leviathan rushed out of the water, and while suddenly spreading his wings, a vast and huge underground world unfolded in front of Lin's eyes.

Sure enough, this place also leads to the underground. Leviathan turned his body and looked back. The place he rushed out just now was a large hole in the cave wall. The endless stream of water in the hole continued to pour out, forming a huge waterfall. Rushing to the ground, the water formed a lake with a diameter of more than 30 meters on the ground.

It's an interesting environment. Now that it's open, Lin can let a large number of troops go underground without having to go through the desert giant pit of the Inca swarm.

Leviathan slowly flapped its wings and landed on the ground. Leviathan's wings are now specially constructed with a compression-expansion system, which allows the wings to expand in an instant, instead of slowly expanding as before, but this also has disadvantages. , occasionally straining the wings. Now the Leviathan has to drop to the ground to repair some of the scars.

There is no fern on the ground here, but a rocky area composed of many large rocks. It is quite far from the location of the brain hunter, but I didn't expect the underground cave to extend here...

About a kilometer away from where Leviathan was located, Lin saw a huge home tree standing between the rocks, against the top of the cave as high as 300 meters. It seems that the home tree may be distributed throughout the ground.

The distance from the desert to the mountain is quite a distance. Lin estimates that the number of home trees from there to here may be hundreds or even thousands. If so many home trees are inhabited by Inca swarms... Then the number of Inca swarms is huge and uncountable. .

But whether every home tree is distributed, or whether there are so many home trees, these are still unknown, in short, it must be thoroughly researched.

Leviathan has now repaired wings. When Lin wanted to fly, she found that there were several creatures with fiery red bodies running out from behind the rock.

This is a lizard with red scales all over its body, and it is a species that Lin is more familiar with-the crystal-scale lizard. Even though the Chibcha worm has become extinct, Lin has found that the crystal-scale lizard is still prosperous, and they are all over the twisted jungle. places, and there are many varieties. The difference between the different species is the color of their scales. I didn't expect that there are also such lizards underground, and they are red.

After Lin looked at them, she flapped her wings, and Leviathan planned to fly to the nearest home tree for research.

Flying through the rocky area of ​​this generation, Lin saw many lizards living here. The ground here occasionally cracks, and a large amount of white mist will be ejected from the cracks. The lizards all gather near these mists and live in small groups.

Lin has not done much research on the environment of this underground world. It is indeed necessary to study the environment. This can allow Lin to learn a lot, so that she can also create an environment.

In order to observe the surrounding environment, Leviathan maintains a slower flight speed. There are a lot of lizards in this rocky land. So far, the Inca swarm has not been seen, only the rocky land and the lizards. Lin also found some other arthropods - cockroaches moving here. This kind of cockroach is red all over, so Lin plans to call them fire cockroaches.

Lin intends to focus on Leviathan's research, which seems to be the edge of the Inca swarm's territory, while the brain hunter is the center. Lin asked the brain hunter to stay there temporarily to excavate the Inca swarm. behavioral research.

When Leviathan flew close to the home tree, the large stones below became less and less, and some potholes with a diameter of about five to ten meters appeared. The potholes were full of clean water, and still Steaming hot, it is likely the same as those hot springs at the foot of the ground.

There is a kind of fish in the hot spring here. Lin has seen such fish in the sea, but it is not really a fish. Their pelvic fins are thick and powerful, and they can crawl on land. There is a name to describe them as 'mudskipper'.

It seems that they are very similar to the transitional species that fish evolved into terrestrial creatures, but in fact mudskippers have no evolutionary relationship with terrestrial salamanders and reptiles. They do climb from the sea to the land, but after that they maintain This fish looks the same, I don't know why? Maybe they're here because it used to be the sea, and they're survivors, or something to do with the Inca swarm...

Looking at the various scenes in this underground world, Lin regretted that she didn't find it in winter. If it was winter, what kind of scene would it be like?

The Leviathan was approaching the home tree. Because the Leviathan's target was too large, Lin stopped at a distance of 100 meters, and released some pilots to approach the home tree to observe.

The flyer first flew around the home tree, and did not find any Inca swarms nearby. There were many other species of creatures living under the tree, such as some terrestrial shellless snails, which can also be called 'slugs'. '.

These slugs are huge and more than three meters long. Because Lin has seen them in the Twisted Jungle and killed them, Lin knows that they are not a type of Inca swarm.

The slugs feed on the dead leaves that fall from the trees. Lin found that there are many of them. When Lin observed the Inca swarm recently, she found that they all like to prey on the creatures next to the home tree, but there are so many slugs here, which means that there are no Inca insects here. group?

The pilot carefully checked the bark and roots of the home tree 20 meters below, and indeed did not find any wooden holes.

Are there really no Inca swarms here? Lin even thought that the home tree was planted by the Inca swarm...

Confused, Lin asked Leviathan to get close to the home tree, and Leviathan released the chewers, which are small units used to dig wood, and they quickly dug a passage in the tree.

Home trees are different from twisted trees. The bark was many times harder, and Lin stopped after digging a small hole and started using another detection method.

Leviathan has been staying in the lake in the mountain peak and researching non-stop. Lin mainly studies electricity, reading brains, etc., but this exploration method was discovered by accident.

It comes from a fish in the murky water at the bottom of mountain lakes. The fish have no vision because they are adapted to their environment, but they use a powerful method to detect their surroundings.

They can emit a very high-frequency 'click' sound, which is transmitted to the surrounding environment in an instant, and by receiving the reflected click sound, various objects can be judged.

Lin's auditory cells can receive this sound, and Lin can imitate it. But how to classify the sound reflected from various objects is the most troublesome place. On the contrary, this kind of fish can clearly distinguish the types of various objects and creatures, and Lin has experienced long-term research, and Lin also knows the difference Whether the various sounds reflected back represent living things or non-living things.

The chewer who digs the tree hole has this organ to send and receive sound. Although Lin doesn't know if it can completely penetrate such a thick home tree, at least she can know the situation in a closer range.

'tattoo...'

The sound made by the chewer slowly spread through the tree's body. Lin waited for the reflection of the voice.

...no response, second trial...third...

Sure enough, there is no Inca swarm activity here. From the reflected sound, Lin can feel that there is not even a hole in this home tree!

So this is Lin's first stop.

In the place occupied by other high-intelligence creatures, Lin didn't want to choose a base seed to develop slowly, but directly let the large troops come in and occupy a larger place.

There is Lin's base and a lot of troops in the mountain lake. But most of the arms in the lake are used for hunting, basically there are only two types of snipers and hunters. The rest is the base body, a huge breeding cabin and some 'defense towers' for escorts. I intend to dissolve some of the troops, convert them into pure nutrients, and carry them over with some troops. After reaching the underground, create new units.

Lin let the troops in the air of the Glittering Woodland also advance in the direction of the mountain, but because of the long distance, it will take some time for them to arrive.

While waiting, Lynn plans to strengthen Leviathan's size. Since Behemoth can't get in, a new 'flagship' is needed in this place and the Leviathan can fill that role well.

So Lin began to let Leviathan prey on the slugs under the tree. Although these creatures abandoned their carapaces, they could secrete a layer of toxins to cover their skin, but for Lin, who had strong filtering ability, they were good prey, and they could also climb. Climb very slowly.

Leviathan devoured a lot of slugs, and Lynn began to increase its size.

The original Leviathan is more than 4 meters, and Lin plans to increase it to ten meters first, and change the way of flying to use gas plus wings and jets.

Ordinary arthropods grow by shedding their shells, but Leviathan, or all of Lin's arms, want to increase their size by first creating a capsule to wrap themselves, and then the capsule will continue to expand as the body grows, growing. When it's done, the sac will burst open, and a whole new class will appear.

When the Leviathan was slowly changing, Lin's troops in the lake were also ready and started to move here.

But why the rush to capture an area here?

Lin vaguely felt it.

'threaten'. (To be continued...)
