4.6 Billion Year Symphony of Evolution

The night came.

Lin's spy is still walking on the sea of ​​clouds. Although this is in the sky closer to the starry sky, there is no star here.

Both above and below, there is a thick sea of ​​clouds. At daytime, the endless cloud sea is quite beautiful, and at night, it feels like it is sandwiched between two dark walls, which seems to be a lot of depression.

At least for the silver armored dragon, it seemed less excited than daylight, but obediently followed the spy, occasionally exclaiming some new things that appeared.

The spy is now observing a group of small creatures in front of them. They are small and can jump on the clouds.

The small creatures in front of the spy are not atmospheric creatures, but ... trilobites.

Their shape is similar to that of a common trilobite, which is 20 centimeters long, but the tail becomes flat and long and can be stretched out after being contracted to bounce.

Lin felt that they were crawling on the sea of ​​clouds, and if they met too far, they could jump over.

This ability obviously evolved here, and their legs have become adapted to catch the soft sea of ​​clouds. This trilobite may have had a chance to come here long ago, and then reproduced.

In other words, this sea of ​​clouds has been here a long time ago ...

How long did it last?Lin is not clear and does not know how to resist storms or other conditions here, but what can be confirmed is that it does maintain a perfect environment.

Such multicellular organisms are not common, and the common ones here are basically atmospheric organisms.

The spy raised his head and looked in the other direction. He saw a large creature with a pair of huge wings floating slowly, more than ten meters away.

'Cloud ray', this is the name that Lin gave them. This creature has a wingspan of about eight meters. It looks like an atmospheric slime, but it is a lot more leisurely. They float leisurely in the sea of ​​clouds under the night and eat occasionally Some mist from the sea of ​​clouds.

Among them, there are two sky whales rolling in the clouds. They are all the same. This atmospheric creature ignores the attitude of the spy and the silver armored dragon. They are not as fierce as the light dragon, but leisurely. Filter eater.

The ecology in the air seems to be similar to the ocean, and it feels very interesting.

Lin and Yinjialong walked past this group of creatures. Next to their feeding place was a cloud mountain of more than ten meters. The spy climbed up from the foot of the mountain.

This piece of Yunshan is also composed of the same jelly as Yunhai. It feels soft and soft, and it feels very interesting to climb up.

For these clouds, Lin has some new research. Lin found that the split clouds will not float away, but will gather together to form a new big cloud. They do not necessarily gather together immediately. But it will never drift away.

Some of the microbes inside co-injected gas to achieve this goal, but why they did so is still unknown.

However, their behavior caused this special 'cloud of sea' not to disperse, but to gather together, but it is not known whether they will be dispersed far away in the case of a storm.

Along the soft mountain, the spy climbed to the top, waiting for a group of spherical transparent creatures on the top of the mountain. When they saw the spy appeared, they immediately flew away.

It feels good to have these creatures everywhere.

And the silver armored dragon stayed underneath. The cause of its listlessness was not only because of the night, but it was also very tired. Because it had experienced too many things, it fell asleep directly under Yunshan ...

Here, there is indeed such a lazy feeling that the soft clouds will stimulate the silver armored dragon's sleepiness.

Although it is dark here, you can still see the surrounding environment clearly. Although the clouds will not emit light, the brightness of this space is almost the same as that of the night illuminated by stars.

The spy climbed to the top of Yunshan Mountain and looked around. Lin first saw a plain of clouds, and some creatures were wandering in the plain.

And Lin climbed up not only to observe the surrounding environment, but also to take a look ... where are the leaders.

Before, Lin wanted to use a special method to lead them out, but now Lin feels it's better to detect them directly.

In this case, there is a sense of 'activeness'.

Lin from the top has now kept the spy with the same level of vision as the silver armored dragon, and has no other perception skills, so it will be much more interesting to observe.

But what if it is used?Maybe you can find something different.

Thinking, the spy slowly closed his eyes, and through some structures in the body, it began to detect the surrounding environment.

Although the spy has no brain, it can receive and feel some brain waves of surrounding organisms, including the radio waves emitted by inanimate bodies, and the pheromones produced by the in vivo activities of atmospheric organisms.

… There seems to be no reaction.

The spy found many creatures within hundreds of meters nearby, but there were no suspicious signals mixed in.

Could it be said that the group of leaders observes further away?This possibility is very small, because there are too many obstacles ... There are too many huge mountains, so they are difficult to observe in the distance. The only reliable way is to use radio waves to detect detailed information.

Next, let's see if there are any subtle detection methods.

Subtle detection means that the leader may observe small things in the cloud or somewhere. Such things can be easily found by sound detection.

……what is this?

The spy found a thick metallic thing in the thick fog not far from here.

The spy jumped from Yunshan and ran before this thing.

Is this ... a metal rod?

The spy pulled this thing out of the cloud. It was more than a meter long and had a diameter of thirty centimeters, although it was silver on the outside and hollow on the inside.

Lin found that the hollow rods were also lined with small, neatly arranged crystals.

This kind of crystallization ... is a relatively rare species, but maybe many here are not necessarily, I do n’t know what it means to set on it ...

This metal rod is part of an object. Lin found that it has interfaces on both sides, and the alloy composition inside is more complicated. Obviously it is not something made by Silver Armor Dragon.

If you can find all of them, you should be able to know what this thing is for ... There is another one here.

The spy saw a similar metal rod nearby, and the spy walked over to pick it up and put the two metal rods together.

Completely agree, they really are together.

And ... there seems to be a lot of things here.

Here, the spies found many metal rods one after another, most of them were hidden in the thick fog of the sea of ​​clouds, and all were put together.

Lin already knows what this is, and this stick can actually receive ... the metal plate that came up before.

'Ka!'Lin ran to the place where he saw that the metal plate had two interfaces facing the sea of ​​clouds, which just matched the metal rod.

... maybe this is ... orbit.

It should look like this, but this track is completely different from the previous one, this one is thinner, and the distance between the two gangs is too far, the ship ’s wheels cannot move right on it, but it can put the ship in two tracks intermediate.

It turned out that, if you came in the normal way, after the silver armored dragon's ship took the metal plate to this position, you could continue to follow the track to a certain place.

However, what method do they use to move?

Because the silver armored dragon's ship is too heavy, it has no way to move across the sea of ​​clouds. It is estimated that it will only sink into the sea and then fall from the sky.

And the usual track is too heavy to be laid on the sea of ​​clouds, and there are many other problems.

In this way, they need another way to move on the sea of ​​clouds, that is, use a lighter track, and then ... let the boat float ...

There are many ways to float, but if it is a metal boat, that method is the best.

That is-magnetic force.

This track may release the magnetic force to make the ship float, and then use the magnetic force to move it, because the crystal inside is just the right thing to do.

But this may have a more complicated structure, and there may be other devices in the hollow stick, in short, it can be confirmed that it is the track structure of the ship.

What makes Lin feel strange is why is it scattered everywhere?Was the orbit attacked by any creature?

Or are they trying to get rid of the track in order to prevent spies from coming in?But in this case, it is impossible for them to throw these metal rods everywhere. Besides, there is no stopping effect.

What happened ... This is more likely.

Maybe there was no surveillance from the beginning?Is it just that the track is just destroyed?

Indeed, this possibility is relatively high, because the spy did not find anything to detect in the vicinity.

Although this orbit can be combined stably, it will still disperse when hit by a large creature.

I don't know if this will happen often, or it happens by accident, but from the track on the road there are some places, Lin can see that this leader does not seem to care about the silver armor from time to time ...

They may not take silver armored dragons as important things, so they are less likely to monitor and do not manage orbit estimates.

Although the track of the cave is very stable, it is only in the upper half, and the part leading to the house has been broken.

In short, find the destination to see what it looks like, and now Lin can calculate the direction of the track paving, and then go along here.
