The cold winter is still going on...... The snow, the frozen sea, the blue moonlight sprinkled all over the land, and countless frecks of light pierced through the branches and leaves of the twisted jungle, adding a pale blue sheen to all the silvery and white things, which was quite a wonderful feeling......

But the creatures here don't think so, and no creature appreciates the beauty, not only because they're asleep, but also because they're about to face the threat of death.

Lin found that the lack of oxygen has now reached the middle of winter, and the problem is quite severe now, the oxygen content of the air continues to decrease a lot, although the current organisms are sleeping, the demand for oxygen is not very large, some organisms do not even need oxygen, but when spring comes, it will be different......

When organisms wake up in the spring, they need to absorb a lot of oxygen to rejuvenate themselves, and if the oxygen level is still at this level by then, it will cause a large number of organisms to die.

I wonder if the vine ferns, which swell in the desert in the spring, can recover their oxygen?

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

And there is no way to find out why...... It seems that there is nothing to be done, although Lin can make a large amount of green carpet to release oxygen, but it is estimated that it has no effect, after all, there was no problem in the previous winter, and the Inca swarm has not recorded this kind of thing, they have even recorded the situation when the first few months arrived, which means that this kind of thing has happened for the first time in history, and it has nothing to do with the month.

So what now?

It seems that there is nothing to do at the moment, only wait, maybe it will get better?

However, Lynn must modify the body structure of most of her classes. in order to adapt to an oxygen-low environment. Especially large arms. Now I am used to a situation where there is a lot of oxygen, and it is difficult to move when there is a lack of oxygen.

Wrong...... It shouldn't just be a class.

This may be an opportunity, but it may not be an opportunity for Linchuang's environment!

Lynn didn't know why there was less oxygen, the air was made up of a variety of gases, and in Lynn's observations, the overall gas levels in the air also became a little strange, with oxygen decreasing the fastest, and the composition of other gases in the air also changing. Some have increased to fill the oxygen gap, while others have decreased, but little has changed.

However, since the air flow is flowing, it is possible that the oxygen is leaking out of somewhere, or it is consumed for some reason, and it is quite likely to be consumed.

Although it is just a guess, Lin can make a real yàn to see.

This might protect some of the creatures.

Take advantage of this winter ......

Lynn began to dispatch a large number of troops, all of them of the same type, known as the 'Shell Painters', which Lynn used to create various chitins. Lynn had the Shell Painters scatter in a circle at a location in the twisted jungle. It is about 300 meters in diameter.

What Lin wanted to create was a safe area where the original oxygen range could be maintained, so that some of the creatures here would not die due to lack of oxygen.

There are not many people who paint the shell of Lin, because it is usually not very useful, and it is basically left over from the manufacture of pioneers, so it can't be built too big, and three hundred meters is already quite large, this job is not difficult, but it is very time-consuming, and it is made in winter, and the efficiency is relatively low, and the cold always slows down biological activities.

Dan Lin also proceeded as fast as she could, mainly to create a semi-circular 'cover' to completely envelop the large jungle, and then inject a large amount of oxygen to maintain the oxygen level at the level before it was lowered, so that the creatures in it could live normally.

Of course, there are many creatures that are not enclosed, and Lynn does not think that lack of oxygen can kill all living things, and there should be some special evolution, so Lynn wants to see how the creatures inside the hood will differ from those outside the hood.

At a later date, Lynn could consider increasing the range of the hood, or building it at sea or even in the air.

It feels good.

In this way, Lynn's shell applicators began to work quickly, piling up the chitins layer by layer like a statue, and adding spider silk to increase stability.

Speaking of which, Lin found that spider silk is really easy to use, and it can greatly stabilize objects, and things that were originally knocked down at the touch can also become unable to explode even after being mixed with spider silk.

Lin also had to prepare some supplies, there was no food in the winter, so she had to use the base to stockpile, but there were quite a lot of reserves, but it felt like a hassle to transport them around under the cold sky.

In this way, the shell painters are rapidly manufacturing, and the winter days and nights are slowly passing......

The snowballs floated in the air day and night, observing, detecting, and looking around the frozen world, and Lynn found that the moon was indeed not getting bigger, it stopped at a certain point and never moved again.

It seems that the moon is close to its limit, and it may retreat next, so that the floating power of the stone may slowly disappear, and then ...... The jungle will be bombarded with boulders.

This is normal, but the head bug can be a little dangerous, and if she sees Narutoshi's levitation decreased, Rin might get it back before it wakes up.

The same goes for the amount of oxygen, which Lin found seemed to slow down after a certain amount of dù.

But by this time, many creatures have already died, but it is difficult to say how many there are, and we still have to wait...... Spring is coming.

In a snowy world, Lynn has been shaping the 'oxygen fortress' of a few creatures, and after more than a hundred days and nights, Lynn has finally completed this special work.

It was a huge cover, the top of the cover was more than fifty meters high, much higher than the largest twisted tree, the whole was made of transparent chitin, which did not affect the exposure of sunlight, and Lin added a lot of 'windows' on it that could be opened and closed, which could put rainwater in and allow air to circulate.

Of course, it is usually locked up to prevent the oxygen inside from being lost, and the edge of the hood is buried to a depth of about ten meters below the ground, which can prevent ordinary digging creatures from leaving.

The cover is about ten centimeters thick, completely sealed, even if it is a virus, it can't float out, and after mixing in the spider silk, it is impossible for ordinary creatures to crash open, unless it is a large creature like the deep sand bus, but if there is really such a creature to collide, Lin will solve it before then.

Next, it's time to start making oxygen.

This is quite simple, you only need to make a bunch of green blankets, constantly absorb light and release oxygen, of course, Lin does not need to make a green blanket in the hood, you can spread it in a wider area outside, and then collect the oxygen and inject it into the hood.

Lin started to do this job very early, a large amount of collected oxygen was mixed with a small amount of gas, and was sent into the hood by a kind of class whose whole body was as inflated as a ball, and after continuously injecting oxygen, Lin found that the oxygen level in the hood began to recover, and at the same time, Lin also released the air with low oxygen content in the original hood, so that the air in the hood would not be too much.

Next, it's time for the biological selection phase.

Lynn needs to choose species that have a small range of activities and don't like to run around, otherwise it would be meaningless to cram those species with a large range of activities into them.

But what species to choose?

In order to create an ecological environment in which the original oxygen range is maintained, it is necessary to select a large number of species, and to ensure that there is no imbalance in the relationship between them.

Lynn provided nothing but oxygen, and they had to be an environment of their own.

It's hard to think about...... All the habits of various creatures must be taken into account, and although the most important thing that Lynn lacks is computing power, this also contains a variety of problems beyond calculation.

Anyway, let's get it first.

Lynn did this with only one purpose, to observe the evolution and change of living things, and the part of living things that gathered a variety of small changes into evolution was quite interesting.

Since it was winter, it was easy for Lynn to dig out the sleeping creatures under the snow, and then dig a burrow inside the hood to put the creatures in, taking care not to have too much impact on the way.

Lin picked many species such as cockroaches, beetles, and bees, and put them in strictly according to the ratio of predators and prey in the jungle, and also divided into large, medium, small and multiple levels, each level is an environment, and the plant aspect is not much to worry about, because there are only twisted trees in this area......

Although there are many kinds of animals, Lin found that there are relatively few plant species, there may be more than a thousand species of large animals, there may be ten thousand species of small animals, but there are only a few dozen species of plants, such as the twisted tree or the home tree.

The growth of plants seems to be more restrictive, mainly because the seeds do not have the ability to disperse, and if they have new ways of spreading, they may evolve

After the placement is completed...... There's not much to do,

Just wait for them to wake up after spring and see how their lives will be different from those outside.

During these cold and boring days, Lynn created a large display in the base to show and simulate the life of various creatures, as well as some wartime situations.

Lynn imagined a new species, had them show up on the displayer, and then had them go to war with some of her own troops.

This seems to be a lot of fun, and it can simulate a lot of situations, which is very helpful for improving the control of the class, tactics, and so on.

While Lynn was playing this 'game', the winter was slowly passing......

Until the arrival of spring, the day when all things wake up.

But this could be a new ...... Mass extinctions. (To be continued......)
