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

Without knowing why, the manufacturing device no longer uses the common house and the like to make the model, but instead uses...air.

Moreover, the place where the manufacturing model is placed is not in this world. Although it is not known where it is, the world is also rapidly thinning from that time.

The entire civilization of ‘flying bricks’ also began to be completely destroyed from that time.

After all, they can still live without houses, but there is no air... they have almost no way.

At the end they tried to store the air, but the air finally disappeared little by little, and the world ushered in an era of no air.

In the end, only a small amount of flying bricks survived.

It is a disease... to save the last remaining small batch of flying bricks.

They are considered to be a disease at least until the end of the world. This disease is called ‘Petrogeneous Disease’.

It is actually a microbial infection that colonizes the epidermis of the organism and slowly shapes a large amount of ... solid material.

Their habits are a bit like corals. In appearance, infected creatures are like a rock-like solid shell that grows from the epidermis, and the longer it grows thicker...

At the beginning of this disease, flying bricks will be treated quickly, so there is no danger, but in the last days... there are not so good treatment conditions, there are many flying bricks that can not be treated after being sick and can only be kneeling on the ground, etc. dead.

As a result they are not dead.

To be precise... it’s a part of the dead, but some of the flying bricks have survived. At this time, the flying bricks have been completely wrapped by the rock-like outer shell, but they have noticed some special things.

Microorganisms don't wrap their limbs, the wings-like structure, which keeps them moving.

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

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

But more importantly, these microbes have made a big difference in their lives.

Microorganisms can absorb nutrients from food on the rock's outer shell, which is why some of them survive.

Because these sick fly bricks are all waiting to die, and the weaker ones are starving to death, but there are still many people who are hungry, but the dead individuals are squatting in the body.

These starving bricks originally thought that the death season was coming, but they felt more and more hungry.

This is because the rocky shells on them are covered with microbes, so when they come into contact with similar corpses, these microbes begin to absorb the bodies as nutrients.

Finally, the microbes also transport nutrients to the body of the flying bricks in the shell, allowing them to regain nutrients and survive.

Therefore, they felt unhungry and able to move in the corpse, and of course they did not know that this came from the same kind of ... corpse nutrient supply.

Microorganisms have even made many changes to their bodies that produce the air nutrients they need... this makes them not need to breathe, and the microbes do another thing, that is, let their bodies adapt to the thin air even No low pressure environment.

In short, this microbe, which was originally thought to be a disease, has made a wonderful transformation of flying bricks, allowing them to live again in the last days.

Although the flying brick civilization has been destroyed at this time, the rest is only a small group of individuals wrapped in rocky shells and difficult to move, but they survived because they soon discovered various nutrients... When the body and expired food are placed on the body, the food is quickly absorbed by the outer shell, and the microbes share the absorbed nutrients to their bodies.

This makes them not have to go directly to eat corpses or expired foods. Microorganisms also filter out the dangers of these deteriorating things, which makes the flying bricks survive and try to rebuild the population.

Because their sensory and reproductive organs are the only 'wings' that are exposed outside the outer shell, they are still active and proliferating.

At the time, they couldn't have the name "flying bricks". First, they wouldn't fly. Second, they were not like bricks.

The shells that microbes make for them are obviously not shaped, and initially they are shaped like a long-winged stone.

In fact, the wing is not a true wing. It cannot be used for flying.

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

The manufacturing device stopped moving after the end of the construction of the flying brick civilization and drained the air.

It doesn't use anything to make a model. To be precise... there is no direct manufacturing model.

Prior to this, the manufacturing devices seemed to be manufacturing the models directly, that is, to transfer the buildings a little bit and throw them back into the model, using the collection device in only a few cases.

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

The remaining flying bricks lived together with the microbes and tried to dig back some of their techniques in the past... I noticed the emergence of collection devices.

These collections appeared in the ruins of the city, and they did what they did before.

It's just collecting and stacking things in one place, and soon the deposits in this place will disappear.

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

At first they were nothing to do, they only looked at the collection device activity.

In general, neither the collection device nor the manufacturing device will harm the living thing, but it is different now.

Flying bricks are found to be collected by the collection device.

This may be because they have a rocky outer shell, and after being collected they are usually thrown in places that cannot escape, such as a pit, and the last collected flying bricks will also be along with other collections. disappear.

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

But flying bricks found a very special place, that is, the collection device... 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 have discovered some of the previous large factories in the ground, and these factories can also be started.

Using these factories, they... made themselves and many things square.
