4.6 Billion Year Symphony of Evolution

The air in the world ... has become sparse since then.

I don't know what the reason is, the manufacturing device no longer uses common houses and similar things to make models, but instead uses ... air.

And the place where the manufacturing model is placed is also not in this world. Although it is not known where, but the world has also become thinner rapidly since then.

The "flying brick" entire civilization was completely destroyed from that time.

After all, they can still live without a house, but without air ... they can hardly do anything.

They tried their best to store air in the end, but the air eventually disappeared little by little, and the world ushered in an era without air.

Finally, only a few flying bricks survived.

Rescuing the last small batch of flying bricks is a disease.

At least until the end of the age they were treated as a disease, and this disease was called 'Petrochemical Disease'.

In fact, it is a kind of microbial infection, which will live on the skin of the organism and slowly shape a large number of ... solid substances.

Their habit is a bit like coral. From the appearance, the infected organism is like a solid shell of rock growing from the epidermis, and the thicker the longer ...

At the beginning of this disease, flying bricks will be treated quickly so there will be no danger, but in the end times ... there are not so good treatment conditions, there are many flying bricks that cannot be treated after lying sick and can only lie on the ground dead.

They didn't die.

To be precise ... part of it was dead, but some of the flying bricks survived. At this time, the flying bricks were completely wrapped by the rock-like shell, but they noticed something special.

Microbes do not wrap their limbs, that is, the pair of wings-like structures, which allows them to move.

Although the whole body seems to be covered with a layer of rock, the material secreted by this layer of microorganisms is actually very light.

This allows them to move quickly, although it will be more difficult than before.

But more importantly, these microorganisms have made a big change in their lives.

Microbes can absorb food on the rock shell to obtain nutrients, which is why some of them survive.

Because these sick flying bricks all lie together and wait to die, and the weaker ones first starve to death, but there are still many hungry individuals who ca n’t move, but still have n’t died.

These hungry flying bricks originally thought that the death period was coming, but they felt less and less hungry.

This is because the rock crust on them is covered with microorganisms, so when they come into contact with similar corpses, these microorganisms begin to absorb the corpses as nutrients.

In the end, the microorganisms also transported the nutrients to the body of the flying brick in the shell, so that they regained the nutrients and survived.

Therefore, they feel hungry and active when lying on their bodies, of course, they do not know that this comes from the same kind ... caused by the supply of nutrients from the body.

The microbes have even made many changes to their bodies. These microbes can produce the air nutrients they need ... This makes them do not need to breathe. The microbes have done another thing, that is, they have adapted their bodies to thin air or even There is no low-pressure environment.

In short, the microorganisms that were originally considered to be diseases have made wonderful changes to the flying bricks, allowing them to live in the end times again.

Although the flying brick civilization had been destroyed at this time, all that remained was a small group of individuals with rocky shells and difficult activities, but they survived because they soon discovered that they had put various nutrients ... When corpses and expired food are placed on the body, these foods will be quickly absorbed by the shell, and the microorganisms will share the absorbed nutrients with their bodies.

This saves them from having to eat corpses or expired food directly. Microbes also filter out the damage of these spoiled things, which makes the flying bricks survive and try to rebuild the population.

Because their sensing and reproductive organs are on the only 'wings' exposed outside the shell, they can still move and reproduce.

At the time, they could not have the name "flying bricks". First, they could not fly, and second, they were not like bricks.

The outer shells made by microorganisms are obviously irregular in shape. At first, their shape is like a stone with long wings.

In fact, the wing is not a real wing, it can't be used to fly but can only be used to crawl.

And they become bricks and fly ... that's another thing.

The manufacturing device stopped the movement after making the end of the flying brick civilization and pumping out the air.

It doesn't use anything to make models, to be precise ... there is no direct model making.

Prior to this, it seemed that the manufacturing devices directly manufactured the models themselves, that is, the buildings were transferred a little bit and the models were thrown back. Only in a few cases were the collection devices used.

And after the air is gone, they no longer make models directly, but rely entirely on ... collection devices.

When the remaining flying bricks lived with the microorganisms and tried to dig out some of their past recovery techniques ... they noticed the emergence of collection devices.

These collection devices appeared in the remains of the city, and they did what they did before.

It is to collect and pile up some things in one place, and the accumulation in this place will disappear soon.

The reappearance of the collection devices caused great fear of flying bricks, so they immediately tried to fight these devices.

At first they had no choice but to watch the collection device moving.

Generally speaking, no matter whether it is a collection device or a manufacturing device, they will not harm living things, but now it is different.

Flying bricks found that they would be collected by the collection device.

This may be because they have a rock-like shell, and after they are collected, they are usually thrown in places where they cannot escape. For example, in a pit, the finally collected flying bricks will also be with other collections. disappear.

Where are they?Was it also made into a model?No one knows, and no one wants to try.

But the flying brick found a very special place, that is, the collection device ... it does not collect square things by itself.

I don't know why the collection device will avoid square objects.

So they began to try to make everything square.

This is mainly because they found some large-scale factories in the underground, which can still be started.

Use these factories ... to make yourself and many things square.
