4.6 Billion Year Symphony of Evolution

During the next few days and nights, Lin summoned many troops from the base on the coast and asked them to start investigating these lairs. From her research, Lin discovered a lot of information.

Lin was able to confirm in the investigation that these bone piles were inhabited by a reptile that was about one meter long, but of course they are not alive.

Lin found the complete skeletons of many of these reptiles in the pile of bones. Lin speculates that they should be starved or thirsty. In addition to them, most of the biological skeletons, carapace, and wood chips are corroded by fungi. Traces, that is to say, this kind of crawling class may be the role of the 'last survivor'.

When the fungus destroyed the whole area, they gathered together and started to build the nest with the bones of some dead creatures, etc., but why use the bones to build?

Lynn believes that they may have discovered the weakness of the plague fungus.

Lin studied and judged from the plague fungus obtained on the road and found that the dust of the plague fungus is more like the seed of the plant than the dust of the general fungus, they are larger, and the internal structure is more complicated, which itself reserves a small amount of Nutrients, but also has a special recognition ability, they generally only stick to the surface of the nutrient-capable objects, including the skeleton, wood, etc., as long as they adhere, they begin to grow,

When encountering ordinary rocks, the sand particles will not stick to them, but continue to drift until they find nutrients. This is a fairly advanced ability that ordinary fungi do not have, but there are some problems.

They cannot identify whether water is contained in the adhered object.

These reptiles have discovered this weakness of fungi. They use dried skeletons to build nests and wear them on their bodies, so that they can adsorb a large amount of dust, and these bacteria will start to grow after adsorption, but they will not be able to obtain it. Moisture causes the small amount of nutrients originally stored in the bacterial dust to be quickly exhausted, and then die.

If they are only covered with rocks or other things, they will not stop the bacteria dust from drilling through the gaps above and enter their respiratory system, but if using skeleton or wood, the bacteria dust will stick to the outside before drilling. .

But even if these reptiles have a way to protect themselves, they can't protect other creatures. They can only watch the entire jungle and various creatures destroyed by the plague. They also die because of lack of food and water.

Lynn found that this should be a smarter creature, they should not understand the structure of the plague fungus, but just stumbled upon the thing that "it will not be infected with bones", but found this and know how to use the already Awesome.

But they are extinct ...?

Perhaps, Lin can still find their traces.

These bone piles have a relatively complete skull at the top, and they are all facing in one direction. Why should they be placed like this?

Maybe it means ... they went somewhere.

Leviathan is now in that place.

The nests of bone piles are basically concentrated more than two hundred kilometers south of the coast, and now Leviathan is located two hundred and thirty kilometers away from the coast. Here, Lin saw a huge ... canyon.

The canyon is quite huge, just like the rift that appears on the ground. Under the vertical cliff is a dark abyss. The whole canyon is filled with dense fog, and it is impossible to see how wide it is. Lin ca n’t confirm it yet. It may or may not be bigger than the canyon that twists the jungle.

At the edge of the canyon, Lin can also see a lot of bone pile nests. The end of these reptiles is at this position. The skulls at the top of their nests all point in the direction of the canyon. On the rock walls of the canyon, Lin Found some traces of them climbing.

Does this mean they entered the canyon?Facing the plague fungus and hunger, these creatures can only hide in this place, which is indeed normal.

So, of course, it is necessary to explore it.

Leviathan flew over the canyon. At this time, Leviathan entered the dense fog all over his body. Lin found that the fog was not water mist, but another gas. The mist formed by the gas enveloped Along the entire canyon, there may be some special structure in the canyon that releases these gases.

However, because it is harmless gas, Lin did not study much.

Leviathan flew down the rock walls of the gorge. The further down, the darker the surrounding vision became, Lin had a general feeling of entering the trench. The rock walls of the gorge went down vertically, and there was no creature on it. , But there are many cracks on it, and it seems that the strange gas forming dense fog is floating out of the cracks.

The traces of reptiles disappeared to a depth of about one hundred meters. Lin felt that they might have fallen, otherwise she climbed back, but Lin did not end her exploration. Leviathan flew all the way to the bottom of the canyon. With a depth of more than two thousand meters, under the canyon, it is a dark world.

The temperature here feels much higher than above, and there has always been a strange quack sound.

This seemed to be a biological cry, and Lynn let Leviathan stretch out glowing tentacles to continue exploring the surrounding environment.

Leviathan is slowly floating, the ground that the light shines on is all rocks, and there seems to be no trace of living things here.

'Boom.'

Leviathan in the search seemed to hit something. Lynn lifted up her tentacles and saw that it was a big sharp stone. The stone was covered with cracks. The sound just now came from this stone.

Feeling suspicious ...

Leviathan suddenly stretched out another tentacle and slammed onto the rock. The stone burst suddenly. The rock was hollow inside, and some skeletons were spread on the ground.

These are the skeletons of those reptiles, they all seem to have died here, and Lin found that one of the reptiles' skulls was making that kind of sound.

Leviathan used his tentacles to take the skull away. Underneath was ... a tiny creature.

This creature Lin has n’t seen it. It ’s a bit like a flying lizard. It is only a few centimeters long. It can be hidden in the skull. Its forelimbs have two wing membranes. The head and hind limbs are stronger than the lizard ’s. It is much thicker, it seems to be a cub, the sound just now is what it sounds like, it should be a creature that is not the same kind as the reptile.

Leviathan poked it with his tentacles, and the little creature screamed, then spread its wings and fluttered as if it wanted to fly, but because it was too young to fly, it could only keep on the ground Shouted.

But Lin felt that there was something else in the little call.
