4.6 Billion Year Symphony of Evolution

After blocking the stone, it is still a long cave. Leviathan continues to swim deep in the cave. This cave is quite mixed. When entering at the bottom of the lake, it goes down, and when it stops, it is up. And now it is down, and at the same time add the route to the left and right, this feeling is like...

roller coaster!

... What is a roller coaster?

No matter what, in short, with the deepening of Leviathan, the original still water does not know why it began to slowly become water, and it is getting faster and faster, because it is downstream, so Leviathan becomes easier, but Later, Leviathan was almost pushed by this stream of water, and the slowly flowing water had turned into a rapids.

And now this channel is just down, along with gravity and water flow, Leviathan rushes down!

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

Lin asked Leviathan to prepare to open the cracks on the sides of the body slowly. When it was close to the light, stretched out the wings and opened the jets behind them!

‘Hey! In this short moment, Leviathan rushed out of the water, and while widening the wings, a wide and huge underground world appeared in front of Lin.

Sure enough, it also led to the bottom of the earth. Leviathan turned his body and looked back. The place that had just rushed out was a large hole in the cave wall. The endless stream of water constantly poured out, forming a huge waterfall. Rushing to the ground, the water formed a lake more than 30 meters in diameter on the ground.

It’s an interesting environment. Since it’s here, Lin can let a lot of troops go underground. It is not necessary to pass the desert crater of the Inca insect group.

Leviathan slowly flapped his wings and landed on the ground. Leviathan's wings now have a special compression expansion system. It allows the wings to stretch in an instant, instead of slowly expanding as before, but it also has disadvantages, occasionally pulling the wings, and now Leviathan landed on the ground to repair some of the scars.

There is no fern on the ground here, but a rocky rock made up of many large rocks. It is quite far from the position of the hunter, but I didn’t expect the underground cave to extend here...

It is about one kilometer from the location of Leviathan. Lin saw a huge home tree standing between the rocky terrain, topped by a cave of up to three hundred meters, it seems that the home tree may be distributed throughout the ground.

From the desert to the mountain, the distance is quite far. Lin estimates that the number of home trees from there to there may be hundreds or even thousands. If so many home trees, each one is inhabited by Inca... The number of Inca swarms is huge and difficult to count.

However, is it true that every tree in the home has a distribution, or whether there are so many home trees, and these are still unknown. In short, thorough research is required.

Leviathan has now fixed the wings, when Lin wants to fly. I found several creatures around the body rushing out from behind the rock.

This is a lizard with red scales all over the body, and is a species that is more familiar to Lin - a crystal lizard. Even though the Chibha worm has become extinct, Lynn has found that the scale lizards are still strong. They are scattered all over the twisted jungle, and there are many different types. The difference between the different types lies in their scales. I didn’t expect this in the underground. a lizard, and it is red.

After Lin looked at them, the wings flew up and Leviathan intended to fly to the nearest home tree for research.

Flying through this generation of rocky areas, Lynn saw many lizards living here, occasionally cracks on the ground, and a lot of white mist sprayed in the cracks. These lizards are gathered near these fogs, with small communities. Way to live.

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

In order to observe the surrounding environment, Leviathan maintains a slow flight speed. The number of lizards in this rock is very large. Until now, I have not seen the Inca group. Only the rock and lizards, Lin found some other The arthropods - the cockroaches in this activity, the cockroaches are all red, so Lynn intends to call them fire.

Lin intends to conduct research on the main side of Leviathan. It seems to be the edge of the Inca worm community, and the hunter brain is the central part. Lin lets the stalker stay there for a while, excavating the Inca worms. Behavioral research.

When Leviathan flew near the home tree, the following large stones were getting less and less, and there were some potholes with a diameter of about 5 to 10 meters. The potholes were full of clear water and still The heat is probably the same as the hot springs at the foot of the ground.

There is a kind of fish in the hot springs here. Lin has seen such fish in the sea. In fact, it is not a fish. Their pelvic fins are thick and strong, and they can crawl on land. There is a name that can describe them as 'fishing fish'.

It seems that they are very similar to the transitional species of fish that evolve into terrestrial creatures, but in fact there is no evolutionary relationship between the squid and the terrestrial scorpions and reptiles. They do climb from the sea to the land, but remain there after that. This fish looks the same, I don't know why? They may appear here because they used to be the sea, and they are survivors, or some reason related to the Inca worms...

Looking at the scenes of this underground world, Lin regretted it and didn't find it in the winter. If it is winter, I don't know what it would be like here.

Leviathan is close to the home tree, because Leviathan's goal is too large, so Lin stopped at a distance of 100 meters, but released some flying people to observe the tree near the home.

The pilot first flew around the home tree and found no Inca insects nearby. There are many other species living under the tree, such as some terrestrial shellless snails, which can also be called '蛞蝓'.

These scorpions are huge, up to three meters long, because Lynn has seen and twisted in the twisted jungle, so Lin knows that they are not a kind of Inca.

The crickets feed on the dead leaves that fall from the trees. Lin found that they are many in number, and Lynn recently observed the Inca worms. They all found that they like to prey on the creatures beside the home tree. But there are so many cockroaches here... I don’t have Inca insects here?

The pilot carefully examined the bark and roots of the home tree below 20 meters. It did not find any wooden hole passages.

Is there really no Inca insects here? Lin even thought that the home tree was planted by the Inca genus...

The doubtful Lin asked Leviathan to get close to the home tree, and Leviathan released the chews, small arms used to excavate the wood, and they quickly dug a passage in the tree.

Unlike the home tree and the twisted tree, the bark has to be hardened many times. After Lin has dug a small hole, it stops and starts to use another detection method.

Leviathan has been waiting in the lake in the mountains and is constantly studying. Lin mainly studies current. Reading brains and the like, but this method of exploration was discovered by chance.

It comes from a fish that is not visibly adapted to the environment in the turbid waters of the mountain lakes, but they can use a powerful method to detect the surrounding environment.

They can emit a very high-frequency ‘嗒嗒’ sound that will be transmitted throughout the environment in an instant, and will be judged by a variety of objects by receiving the reflected hum.

Lin's auditory cells can accept this kind of sound, and Lin can imitate it, but how to classify the sounds reflected by various objects is the most troublesome place. In contrast, this fish can clearly distinguish the types of objects and creatures. While Lin has been studying for a long time, Lin also knows whether the various sounds reflected separately represent biological or non-living.

The chews who dig the tree hole have the organ that sends and receives the sound. Although Lin does not know whether he can completely penetrate such a thick home tree, at least he can know the nearer range.

‘嗒嗒...’

The sound made by the chews spread slowly in the body of the tree, and Lin waited for the reflection of the sound.

... no response, the second test... the third time...

There is no activity of Inca insects here. From the sound of reflection, I can feel that there is not even a hole in this tree!

Well, this is the first stop for Lynn.

In places where other intellectual high creatures occupy, Lin does not want to choose a base to slowly develop, but directly let the large forces come in and occupy a larger place.

There are Lin's bases and many troops in the lake of the mountain, but most of the troops in the lake are used for hunting. There are basically only two types of snipers and hunters. The rest is the base body, a huge one. The breeding cabin and some of the 'defense towers' used by the guards, Lin intends to dissolve some of the troops, transform them into pure nutrients, and then carry them with some arms, and then build new units after reaching the underground.

Lin let the troops in the flash woodland also move in the direction of the mountain, but because of the distance, it will take some time for them to arrive.

In the process of waiting, Lin intends to strengthen the shape of Leviathan, because Behemoth can't get in, so a new 'flagship' is needed in this place and Leviathan can play this role well.

So, Lin began to let Leviathan prey on the cockroaches under the tree. Although these creatures abandoned the shell, they secreted a layer of toxin to cover the skin, but for Lin, who had strong filtering ability, they were good prey, and they climbed. Climbing is very slow.

Leviathan swallowed a lot of cockroaches, and Lin began to increase its size.

The original Leviathan is more than 4 meters, and Lin intends to add it to the first ten meters. The flight method is changed to three kinds of gas plus wings and jets.

Generally, the limbs are grown by shelling, but all the branches of Leviathan, or Lin, need to make a capsule to wrap themselves up. Then the capsule expands as the body grows and grows. When the capsule is finished, the capsule will split and a new unit will appear.

When Leviathan slowly changed, Lin’s lake troops were ready to start.

But why are you so anxious to occupy an area here?

Lynn felt vaguely.

‘threaten’. (To be continued, please search for astronomical literature, the novel is better updated faster!
