The winter is still going on... the heavy snow in the sky, the frozen ocean, the blue moonlight shining over the earth, the countless spots penetrating the branches and leaves of the jungle, adding a layer of pale blue luster to all the silver objects. It feels quite wonderful...

But the creatures here don't think so, no creatures will appreciate these beauty, not only because they are in a state of sleep, but also because they are about to face – the threat of death.

Lin found that the lack of oxygen has reached the middle of winter. The problem is quite serious now. The oxygen content of the air has been continuously reduced. Although the living creatures are sleeping, the demand for oxygen is not very large. Some creatures do not even need it. Oxygen, but it will be different when the spring arrives...

Spring creatures need to absorb a lot of oxygen to rejuvenate when they wake up. If they still have such oxygen content at that time, it will cause a lot of biological death.

I don't know if the vines that thrive in the desert in spring can restore oxygen?

However, they only grow for a while, and then there will be problems, and the problem may not be solved by a jungle.

And now there is no way to find out the reasons... It seems that there is no way. Although Lin can make a large number of green carpets to release oxygen, it is estimated that it has no effect. After all, there is no such problem in the previous winter, and the Inca population is not recorded. After this kind of thing, they even recorded the situation when the previous months arrived, which means that this kind of thing happened for the first time in history, and it has nothing to do with the moon.

So what do you do now?

It seems that there is currently no way, only waiting, maybe it will get better?

However, Lynn must transform the body structure of most arms. In order to adapt to the environment of low oxygen. Especially large arms. Nowadays, when you are used to oxygen, it will be difficult to move in the absence of oxygen.

No... No, you should only transform the arms.

This may be an opportunity, and it is not necessarily a chance for Lin to create an environment!

Lin doesn't know why oxygen is less. The air is made up of a variety of gases. In Lin's observation, the overall gas level in the air has become a bit strange. The oxygen is the fastest, and the other gas components in the air are also available. change. Some have increased to fill the gap in oxygen, and some have also decreased, but there has been little change.

However, since the airflow is flowing, the oxygen may leak out from it, or it may be consumed for some reason, and the possibility of being consumed is quite large.

Although it's just a guess, Lynn can do an experiment.

This may protect some of the creatures.

Taking advantage of this winter...

Lin began to dispatch a large number of arms, all of which are of a type, known as the 'sheller', and Lin used shellers to make a variety of shells. Lin let the shellers disperse and form a circle in a position in the twisted jungle. It is about three hundred meters in diameter.

Lynn wants to create a safe area that maintains the original oxygen level and keeps some of the creatures from dying due to lack of oxygen.

Lin's shells are not too many, because the usual use is not very big, basically it is left when the pioneers are made, so it can't make too big a place, and the three hundred meters is quite big, this work is not Difficult, it is very time consuming, it is made in winter, and the efficiency is relatively low. The cold always makes the biological activity slow down.

But Lin is also doing the fastest speed, mainly to make a semi-circular 'cover', completely cover the large jungle, and then inject a lot of oxygen, so that the oxygen content is maintained at the level before the reduction, so that inside The creature can live normally.

Of course, there are a lot of creatures that are not covered. Lin doesn't think that hypoxia can kill all creatures. It should produce some special evolution. Lin wants to see what the difference between the creature inside the cover and the outside of the cover. .

Later, Lin can consider increasing the scope of the hood, or building it on the sea or even in the air.

It feels good.

In this way, Lin's shellers began to work quickly, they are like building a statue, pile up the shells layer by layer, while adding spider silk to increase stability.

Speaking of Lin, I found that the spider silk is really easy to use, and it can greatly stabilize the object. The original thing that was poured down can also be blown up after the spider silk is mixed.

Lin has to prepare some resuppliers. There is no food in winter. I have to use the reserves in the base, but the reserves are quite large, but it is very troublesome to transport them under the cold sky.

In this way, the shellers are in the process of rapid manufacturing, and the winter nights and nights are slowly passing...

Snowballs float around the sky with the wind and snow around the clock. They observe, detect, and look at this frozen world. Lin finds that the moon is not getting bigger. It stops at a certain point and never again. Moved over.

It seems that the moon is nearing the limit, and then it may retreat, so that the floating force of the stone may slowly disappear, and then... the jungle will be bombarded by a huge stone.

This is normal, but the brain worm may be a bit dangerous. If you see the floating height of the sapling, Lin may get it back before he wakes up.

The same is true for the amount of oxygen. When Lin found that oxygen seemed to be reduced to a certain extent, it began to slow down the rate of reduction.

But to this extent, many creatures have already died, but how many are hard to say, still have to wait... the arrival of spring.

In the snow-filled world, Lynn constantly shaped the 'Oxygen Fortress' of a few creatures. After spending a hundred or more nights, Lin finally completed this special work.

It is a huge cover, the top of the top of the cover is more than 50 meters higher than the largest twisted tree. The whole is a transparent shell, which does not affect the sunlight, and Lin adds a lot on it. The 'window' that can be opened and closed can be used to put rainwater or allow air to circulate.

Of course, it is usually locked up, so as to avoid the loss of oxygen inside, and the edge of the cover is buried deep in the depth of about ten meters, which can prevent the general digging creatures from leaving.

The cover is about ten centimeters thick and completely sealed. Even if the virus can't float out, after the spider silk is mixed, the creatures are impossible to knock open, unless it is a large creature of the deep sand bus, but there is really such a creature to hit. Then, Lin will solve it before then.

The next step is to start making oxygen.

This is quite simple, just need to get a pile of green carpet, constantly absorb the light to release oxygen, of course, Lin does not need to make a green carpet in the cover, can be spread outside the wider place, and then collect the oxygen, inject Inside the cover.

Lin started this work very early. A large amount of collected oxygen was mixed with other small amounts of gas. It was sent into the hood by a whole body that was inflated like a ball. After continuously injecting oxygen, Lin discovered the oxygen in the hood. The level begins to recover. At the same time as the injection, Lin also releases the air with low oxygen content in the original cover, so that the air inside the cover is not excessive.

Next, it is the stage of biological selection.

Lin needs to choose some species that have a small range of activities and don't like to run around. Otherwise, if those species with a large range of activities are forced into it, it doesn't mean anything.

But what species do you want to choose?

Inside the hood is an environment that maintains the original degree of oxygen, which can be called 'isolated'. If you want to create an ecological environment, you must choose a very rich species, and also ensure that they are between The relationship will not be unbalanced.

Lin does not provide anything except oxygen. They must be in an environment.

This is hard to think about... It is necessary to take into account all the habits of many kinds of creatures. Although Lin is the most indispensable is the computational power, but it also contains many problems beyond calculation.

Anyway, let's get it first.

There is only one purpose for Lynn to do this. Observing the evolution and change of living things, the creatures have integrated many small changes into evolution, and this part is quite interesting.

Because it is winter, it is easy for Lin to dig up the sleeping ones under the snow, and then dig the caves in the hood to put these creatures in. You need to pay attention to not have much influence on the way.

Lynn has picked up many species of cockroaches, beetles, and bees, which are strictly in accordance with the proportion of predators and prey in the jungle, and are also divided into large, medium and small scales, each of which is an environment, a plant aspect. It doesn't matter how much it is, because this band only has a twisted tree...

Although there are many kinds of animals, Lin found that there are fewer plant species. There may be more than one thousand species of animals, and there may be thousands of small ones. However, there are only a few dozen plants, such as large trees such as twisted trees or home trees. Several.

Plant growth seems to be more restrictive, mainly due to insufficient seed transmission ability, and may evolve if they have new modes of transmission.

After the placement is completed... there is nothing to do,

Just wait for them to wake up after the spring and see how their lives differ from the creatures outside.

In this cold and boring day, Lynn made a large display in the base to show and simulate the state of life in various creatures, as well as some wartime situations.

Lynn imagined a new species that showed them on the display and then let them fight with some of their arms.

This seems to be very interesting. It can simulate many kinds of situations, which is very helpful to improve the control, tactics and so on.

Just as Lynn did this kind of 'game', the winter slowly passed...

Until the arrival of spring, the day when everything wakes up.

But this may be a new... species extinction. (To be continued, please search for astronomical literature, the novel is better updated faster!
