4.6 Billion Year Symphony of Evolution

The winter is still going on ... the sky is full of snow, the sea is frozen, the blue moonlight is scattered all over the earth, and countless light spots penetrate the branches and leaves of the twisted jungle, adding a silvery luster to all silver and white objects. It feels pretty wonderful ...

But the creatures here don't think so, no creatures will appreciate these beauty, not only because they are sleeping, but because they are 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 serious. The oxygen content of the air has continued to decrease a lot. Although the current organisms are sleeping, the demand for oxygen is not very large, and some organisms do not even need Oxygen, but it will be different when spring comes ...

Biological recovery in spring needs to absorb a lot of oxygen to restore vitality. If the oxygen content is still at that time, it will cause a large number of biological deaths.

I wonder if the vine fern that surged in the desert in spring can restore oxygen?

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

And there is no way to find out the reason ... It seems that there is no way. Although Lin can make a lot of green carpets to release oxygen, it is estimated that it has no effect. After all, there was no problem in the previous winter, and the Inca insect swarm was not recorded. After this kind of thing, they even recorded the situation when the previous few months came, which means that this kind of thing happened for the first time in history, and it has nothing to do with the month.

So what now?

There seems to be no way at all, only to wait, maybe it will get better?

However, Lin must transform the body structure of most arms to adapt to the low oxygen environment, especially the large arms. Now they are accustomed to the situation of high oxygen, and it will be difficult to move when there is a lack of oxygen.

No ... You shouldn't just reform the arms.

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

Lin did n’t know why the oxygen became less. The air was composed of multiple gases. In Lin ’s observation, the overall gas level in the air also became a little strange. Among them, the rate of oxygen reduction was the fastest, and other gas components in the air also had Changes, some increased to fill the vacancy of oxygen, and some have decreased, but there is little change.

However, since the air flow is flowing, it is possible that oxygen leaked from it, or was consumed for some reason, and the possibility of being consumed is quite large.

Although it is just a guess, Lin can do an experiment to see.

This may protect some creatures.

Taking advantage of this winter ...

Lin began to dispatch a large number of troops, all of which were of the same type, called 'shellers'. Lin used shellers to make various shells, and Lin let the shellers spread out in the twisted jungle At a location around 300 meters in diameter.

Lin wants to create a safe area that can maintain the original oxygen level, so that some of the creatures here will not die due to lack of oxygen.

Lin ’s shell painters are not many, because they are usually not very useful, and they are basically left when they are pioneers, so they ca n’t make too much space, and 300 meters is already quite large. This work is not. Difficult, it is very time-consuming. It is manufactured in winter, and the efficiency is relatively low. The cold always slows down the biological activities.

But Lin also carried out at the fastest speed, mainly to create a semi-circular 'hood', completely cover the large jungle, and then inject a large amount of oxygen to maintain the oxygen content at the level before the reduction, so this Creatures can live normally.

Of course, there are a lot of creatures that are not covered in. Lin does not think that hypoxia can kill all creatures. It should produce some special evolutions. Lin wants to see how the creatures inside the hood are different from those outside the hood. .

In the future, Lin may consider increasing the range of the hood, or building it at sea or even in the air.

It feels good.

In this way, Lin's shell coaters began to work quickly. They piled up shells layer by layer like a statue, while adding spider silk to increase stability.

Speaking of which, Lin found that the spider silk is really easy to use, and it can greatly stabilize the object. What was originally knocked down can also not be exploded even after the spider silk is mixed.

Lin also had to prepare some supplies. There was no food in winter, so she had to use the reserve in the base. However, the reserve is quite large, but it feels troublesome to transport it under the cold sky.

In this way, during the rapid manufacturing process, the day and night in winter slowly passed ...

The snowball floats in the sky day and night with the snow and snow. They observe, detect, and look around this frozen world. Lin found that the moon is indeed not getting bigger. It stops at a certain point and never again. Moved.

It seems that the moon has reached the limit position, and then it may retreat, so that the floating force of Naruto may slowly disappear, and then ... the jungle will be bombarded by some boulders.

This is a normal thing, but head worms may be a little dangerous. If she sees the floating height of Naruto decrease, Lynn may get it back before it wakes up.

The same is true for the amount of oxygen. After Lin found that the oxygen seemed to decrease to a certain level, she began to slow down the rate of decrease.

But at this level, it has already caused many creatures to die, but how many are difficult to say, still have to wait ... the arrival of spring.

In the world of heavy snow, Lin kept shaping the "oxygen fortress" of a few creatures. After using more than 100 days and nights, Lin finally completed this special work.

It is a huge hood. The top of the hood is more than fifty meters high, which is much higher than the largest twisted tree. The whole is made of transparent shell, which does not affect the sunlight, and Lin added a lot on it. A 'window' that can be opened and closed, where rainwater can be put in, and air can be circulated.

Of course, it is usually closed to avoid the loss of oxygen inside. In addition, the edge of the cover is buried in the depth of about ten meters underground, which can prevent the general ground-digging creatures from leaving.

The cover is about ten centimeters thick and is completely sealed. Even if the virus cannot float out, it is impossible for ordinary creatures to break apart after mixing in the spider silk, unless it is a large creature like the deep sand bus, but there is really such a creature to strike If so, Lynn will solve it before then.

Next, it is time to make oxygen.

This is quite simple, just need to get a pile of green blankets, constantly absorbing light to release oxygen, of course, Lin does not need to get a green blanket inside the cover, it can be spread on a wider area outside, and then collect and inject oxygen Within the hood.

Lin began to do this work very early. A large amount of collected oxygen was mixed with other small amounts of gas, and was sent into the hood by a swollen body that was like a ball. After continuously injecting oxygen, Lin found that the oxygen in the hood The level began to recover. While injecting, 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 is the stage of biological selection.

Lin needs to choose some species with a small range of activities and doesn't like to run around, otherwise it wouldn't make any sense to force those with a large range of activities into it.

But, what species to choose?

The inside of the hood is an environment that maintains the original oxygen level, that is, an environment that can be called 'isolated from the world'. If you want to create an ecological environment inside, you must choose a very rich species, and also ensure that they are between Problems, such as imbalances.

Lin provided nothing but oxygen, they had to form their own environment.

It's hard to think about it ... it is necessary to take into account all the habits of various creatures. Although Lin's most important thing is computing power, it also contains many problems beyond calculation.

Anyway, get it first.

Lynn has only one purpose to do this. Observe the evolution and changes of creatures. Organisms gather many small changes into evolution. This part feels quite interesting.

Because it is winter now, it is easy for Lin to dig out the sleeping ones under the snow, and then dig a cave in the hood to put these creatures in. You need to pay attention to the way there must not be too much impact.

Lin picked many species of cockroaches, beetles, bees and other species, strictly according to the proportion of jungle predators and prey, and also divided into large, medium and small levels, each level is an environment, plant aspects It doesn't matter how, because there are only twisted trees in this area ...

Although there are many types of animals, Lin found that there are relatively few types of plants. There may be more than a thousand species of large animals and tens of thousands of small ones. Several.

The growth of plants seems to be more restrictive, mainly due to the lack of seed transmission ability. If they have new transmission methods, they may evolve

After placement, there is nothing to do,

Only wait for them to wake up after the spring to see how their lives will be different from the creatures outside.

During this cold and boring day, Lin made a large display at the base to display and simulate the state of life of various creatures on it, as well as some situations during war.

Lynn imagined a new species, let them be displayed on the display, and then let them fight some of his arms.

This seems very interesting, because it can simulate many kinds of situations, which is very helpful to improve the control of arms, tactics, etc.

While Lin was playing this kind of 'game', the winter also slowly passed ...

Until the arrival of spring, the day when everything awakens.

But this may be a new ... species extinction.
