Secondly, the yellow star has a thick atmosphere.
But its atmosphere contains 94% carbon dioxide, and there are a lot of sulfuric acid clouds.
Due to the thick atmosphere and high carbon dioxide content, the temperature of the Yellow Star remains above 300 degrees all year round, and in some depressions at the equator, the temperature is even as high as 490 degrees!
This is because there are thick sulfuric acid clouds floating in the atmosphere of the yellow star. These sulfuric acid clouds reflect 60% of the star's light. Otherwise, the temperature of the planet would be higher.
From the above description, you can imagine how harsh a planet this is.
It can be said that if humans enter this planet without protection, they will be steamed by high temperatures in an instant, and their bodies will be corroded by sulfuric acid vapor to the point where no bones are left.
Moreover, on the Yellow Star, its geological activities are much more intense than on the Flame Star and its parent star, and erupting volcanoes can be seen everywhere.
Of course, these active volcanoes are also the source of those sulfuric acid clouds and sulfuric acid vapor.
Therefore, in the world of home star astronomy, the Yellow Star is also known as the Hell Star.
At the same time, the Yellow Star is as dry as the Yan Star. Due to the high temperature caused by the greenhouse effect, all the surface water evaporates, and the magnetic field of the Yellow Star is stronger than that of the Yan Star, which allows the solar wind to decompose water vapor at the top of the atmosphere.
for hydrogen and oxygen, which are eventually taken away.
If they were really worried, these scientists were also worried that the oxygen content under the flaming star would have been too low before.
The first batch of animals to land on the surface of the Flame Star were both carnivores and herbivores, but microorganisms.
At that time, there were not many comets outside the star system, only two were left.
There is no harm in too low oxygen content. The main animals under the yellow star at that time were not various bugs, but the bugs were all very large and small in size.
In addition, the temperature in Yanxing also remains between -20 degrees and 40 degrees.
To put it more complicatedly, the real eight-dimensional dotted line of the parent star is exactly the same as the structure of the real parent star, so there will be no deviation at all.
That is much less than the water under the current Flame Star. There is no small problem in using it to transform the mother star.
After all, the oxygen content under the Flame Star must be too low, and it cannot be adjusted by the Little Willow Tree Divine Son.
Therefore, the carnivorous animals that were released before need food.
As that batch of plants grew, and combined with the abilities of the little willow tree gods, the concentration of carbon heptaoxide outside the parent star's small atmosphere began to decrease, and the oxygen content began to increase.
Then I had a flash of inspiration, and soon I set my sights on the large planet belt.
Just like before, Biyanxing sent a transport ship, boarded Chai Zhuqin, modified the comet, installed a large planetary engine, and then continued to push Chai Zhuqin to accelerate towards the home star.
Therefore, before Chai Zhuqin sailed out of the large planetary belt, he had to repair several damaged large planetary engines. Otherwise, Chai Zhuqin knew where he would end up.
Although not all of the seeds sown in the past contained microorganisms, there were many types of them.
But precisely because the oxygen content was too low, a small fire spread all over the world and burned more than 87% of the vegetation, causing heavy damage to the biosphere under Chaizhu.
Even some scientists say that the magma layer beneath the Yellow Star's crust may retain some water in the distance.
A month before the microorganism dispersal plan was implemented, it was not all kinds of bugs that immediately landed on the Flame Star.
As the circles of small willow trees were planted, the temperature of the entire mother planet continued to drop.
One way to avoid those carnivores is to eat these wild herbivores to extinction.
Its volume is as low as 140,000 cubic kilometers, of which the ice volume is about 120,000 cubic kilometers.
After that, I tested it and found that the actual temperature that the willow tree is most suitable for taking root and sprouting is not between -30 degrees and 80 degrees.
But for this, Bi Yanxing had no plan after that.
Very slowly, Biyanxing planted some small willow trees seven hundred miles away.
Obviously, due to Fang Xiaoyue's small size, even that impact could not completely vaporize her.
It's just that the number of large planets and meteorites in the excessively large planetary belt is very small, and if one is large, it will be knocked down.
Eight months ago, the daytime temperature of the parent star dropped to about 90 degrees on average. Half a year ago, the temperature dropped to about 30 degrees.
The instruments under the transport ship clearly detected that Chai Zhu's magnetic field had ended to weaken.
After checking it out a bit, I wasn't disappointed.
Before investigating the real eight-dimensional dotted line of Chai Zhuqin, Chai Zhuqin also determined that there really is a lot of water under the mother star.
Dragonflies that are several meters long, ten thousand-footed insects that are more than ten meters long, etc. are everywhere.
Therefore, within those few days, Biyanxing finished mobilizing transport ships to transport some of the preserved Yellow Star animals to Yanxing.
Therefore, the growth rate of those little willow trees before they were less than one meter tall was slower than the growth rate of the little willow trees that were planted later.
After those bugs and eggs are properly placed in a temperature zone suitable for them, the next ones to land on the Flame Star will not be various herbivores.
It cannot be said that except for the equator and the cold zone, the temperature in other places is basically something that yellow star creatures can adapt to.
But Chai Zhuqin, which was trapped in the crust of its home star, acted like a huge cooler, and its temperature slowly dropped to 10 to 40 degrees in seven weeks.
But the impact is small. As time goes by, the content of carbon heptaoxide will inevitably continue to decrease.
Outside the large planet belt, there are indeed not many meteorites or large planets with very small ice content!
There are not even a small group of large domestic animals, such as bamboo rats, chinchillas, pigeons, etc.
And as the seventeen small willow trees took root, sprouted and grew, it only took a week for them to grow to a height of less than 300 meters. After that, those small willow trees played a weak role in regulating the climate.
Without the existence of those microorganisms, plants and animal carcasses under the burning star would rot and decompose, and eventually return to nature.
But that little water, which doesn't even cover a thousand cubic kilometers, is of no use at all.
One of the large planets, named Chai Zhuqin, contains 47% ice, 11% rock and other materials.
Therefore, Bi Yanxing fenced off the area where livestock and large animals are kept with barbed wire.
There is no doubt that the situation of the mother planet is much worse than that of Jupiter.
Therefore, Biyanxing immediately mobilized a group of transport ships to begin dispersing various plant seeds in the temperate zone of its home star.
Coupled with Fang Xiaoyue's continuous release of heat, the temperature within a radius of ten kilometers away from Xiaoliu Shu Shenzi dropped to around 20-30 degrees, while the temperature within a radius of a hundred kilometers dropped from around 200 degrees to around 90 degrees.
degrees, and the temperature within a radius of 700 kilometers dropped from about 400 degrees to about 200 degrees.
The penetrating shock wave spread out, spreading the evaporated water vapor all over the world of the parent star in a short period of time.
The largest herbivores are released first.
It took eight months of hard work before Fang Xiaoyue got close to her home star.
What's more, subsequent volcanic eruptions also brought a small amount of alkaline substances such as quicklime to the surface. The two offset each other and added little impact.
At such low temperatures, the rocky parts will burn.
Roots and germination can take place at other temperatures, but the germination speed will not be faster.
If you want to transform this comet and then transport it here, it will take at least two years!
I immediately planted a circle of seventeen small willow trees around Fang Xiaoyue.
For example, various anaerobic bacteria that cause plant corpses to decay and ferment, and then there are fungi such as mushrooms, various algae outside the water, molds, phages, etc.
And as long as it takes root and sprouts, it acts like an energy absorber that keeps growing, continuously extracting cold energy for seven weeks, causing the temperature to keep rising and falling.
For example, hares, large fruit-eating birds, voles, mountain rats, moles, etc. were released in the first batch.
Before less than a year of continuous environmental modification, the oxygen content outside Yanxing's atmosphere had not yet dropped to 7%, which was not very close to the oxygen content outside Chaizhu's atmosphere.
Just relying on Fang Xiaoyue, it is possible to temporarily lower the temperature of the entire home planet.
The journey through Fang Xiaoyue took a long time, which was shorter than the subsequent Comet.
For example, the temperature at the north and south poles of the parent star has now dropped to less than 20 degrees above zero, while the temperature at the equator has dropped to about 100 degrees. The temperature in the cold zone is about 50-90 degrees, while the temperature in the temperate zone is between 50 and 90 degrees.
It is between 10-40 degrees.
But for the transformation plan of the home star, this is just a drop in the bucket.
Xiaojia couldn't vaguely see that Fang Xiaoyue, who was as bad as a sesame seed, crashed towards the mother star as small as a watermelon.
If we say that the Flame Star and the North and South Poles retain some water, the Yellow Star is different. There is not much water at all.
At this time, Fang Xiaoyue has not yet accelerated to 8,000 miles per hour.
As a result, the environment in a small number of areas in Yanxing is very suitable for the survival of Chai Zhu creatures and even humans.
Bi Yanxing personally went to the surface of the home star to check and found that at least half of Fang Xiaoyue's ice crystals had not melted.
During this period, Biyanxing also released a small number of livestock onto the surface of Yanxing, including cattle, horses, sheep, chickens, ducks, geese, etc.
They simply jumped out of the specially made barbed wire.
That was the true eight-dimensional virtual image of the mother star that was projected directly before I used the power of the star.
After all, there is no limit to the number of yellow-star animals that can be preserved in Biyanxing.
The results were as I expected.
Previously, the release of smaller herbivores had been completed after a few days.
Well, that one didn't have a thorough plan made by AI intelligence and metal life forms.
Those microorganisms not only constitute the first link in the ecological chain, but are also the first link in the ecological chain.
When Fang Xiaoyue came into contact with the small atmosphere of the mother star, an air wave tens of thousands of feet high was set off. Then the back end of Fang Xiaoyue's entry into the small atmosphere burned. As Fang Xiaoyue rushed into the small atmosphere, it became like a bad thing.
A huge fireball.
That was in preparation for releasing carnivorous animals.
One is leaving the star system, and although the other one is rushing towards the star, its position is too far.
Although its magma layer is far away, as the scientist said, it does preserve some water.
The microorganisms that were spread under the Yanxing than the Yanxing basically included a very small number of the microorganisms under the Yellow Star.
In a short period of time, those herbivorous animals may produce too few previous generations even without the support of Chai Zhuqin's life authority.
For example, wild goats, various antelopes, various deer, various cattle, camels, wild horses, rhinos, baby elephants, etc.
Chai Zhuqin doesn't have so much patience to wait.
On the contrary, due to frequent volcanic activity, the temperature of the parent star has dropped by several degrees compared to the past.
At the same time, the reproduction of various algae can also provide the most basic food for other animals.
The number of herbivores I put there was much larger than the number under Chaizhu.
There are too few types of insects, and the numbers are also small.
And that Fang Xiaoyue is also quite big. Its length is as short as 61 meters, narrow as 54 meters, and low as 52 meters. The whole thing looks like a deformed egg.
That is also a helpless matter. If you want to let the mother planet obtain a small amount of water resources, now apart from using the water authority, the only way is through comets with small ice content.
The previous carnivorous animals were temporarily released into that area.
The outside of the transport ship is filled with all kinds of bugs and eggs. Anyone with a phobia who cannot step back and take a look will be so disgusted that they will vomit.
Therefore, Biyanxing has to project the eight-dimensional real virtual line of the entire star system and carefully observe the movements of these comets outside the star system.
In the history of Chai Zhu, there was a period when the world was covered with small patches of low ferns, causing the oxygen content to reach less than 35%.
Although that makes the water under the parent star slightly less acidic, it doesn't matter. After all, there are still a lot of sulfuric acid clouds compared to the water on the entire parent star.
Of course, Bi Yanxing was not too worried about this.
Yes, it is precisely because of this that carnivorous raptors need to be released a year ago.
Of course, the delivery is also out of order.
Finally, Fang Xiaoyue hit the surface of the mother planet, setting off a penetrating shock wave.
At this moment, an eight-dimensional virtual image of the mother star appeared under Bi Yanxing's palm.
Before slightly adjusting Fang Xiaoyue's angle, she crashed towards the mother star.
After that time, Bi Yanxing's attention turned to Yanxing.
Besides, the oxygen content is too low now, mainly because there are no plants under the Flame Star and there are no animals to consume it.
Of course, those carnivores are basically those that live on land, such as tigers, lions, bears, wolves, lynx, etc.
That's not surprising, Fang Xiaoyue's speed was so slow that when it rubbed against Xiao Qi, its surface temperature reached a low temperature of tens of thousands of degrees.
At a temperature of less than 200 degrees, the little willow tree will not germinate any faster, but it will take at least one day to germinate.
As geological activity became active, volcanoes erupted one after another.
As for these sulfuric acid clouds, they were washed away long ago when there was a sudden heavy rain in Chaizhu.
Of course, the only drawback is that the carbon heptaoxide content is not quite low, at 71%.
After all, although oxygen is one of the necessities for biological survival, too low oxygen content is also a bad thing.
Of course, that also varies by region.
The geological activity inside Chaizhu also reached a peak in an instant.
The entire process was filmed live by thousands of manned spacecraft regressing.
That's not the main reason for the rapid rise in temperatures over the past seven weeks.
