Lin Dong's approach is equivalent to rapidly compressing the earth for 4.7 billion years. As we all know, the earth can reach a planet like today, and it is surrounded by a thick aerobic atmosphere.

The Earth itself has gone through about 4.7 billion to 5 billion years. From the core of the fireball at the beginning to the standard space miracle that was formed later.

This should cost at least about 5 billion years. And there are many coincidence factors, such as a large celestial body formed on the inside of the orbit colliding with the earth, knocking the earth's orbit away from the earth.

A perfect circular track.

The current earth has an orbit of about 45 degrees, which forms the irradiation from the earth to the sun, and the distance has been changed from the original direct frontal illumination to radioactive up and down illumination.

In this way, the powerful solar infrared heat source light waves received by the earth from the sun no longer form a complete and uniform coverage on the surface directly opposite the earth, but instead form a relatively thin upper and lower ends and relatively thick middle coverage.

This also forms the two poles of the earth, the Antarctic and the North Pole ice caves. Because the temperature of the horizontal infrared luminosity covered by the sunlight cannot be thawed, the earth's water source is frozen all year round.

These water sources can only be gradually melted and injected into the earth's ocean little by little as the atmospheric temperature rises.

Allowing the Earth's oceans to integrate these huge freshwater systems will ensure the stability of the Earth's oceans' pH.

Of course, these are all methods of heavenly palace manufactured by nature. Lin Dong is now using manual intervention. The earth has formed such a system, and it took at least 4 billion years for the water circulation system.

The life system on Earth began to explode in the Cambrian period. The microbial age appeared in the 200 million years before this.

It took about 700 million years to reach the Earth of Advanced Interstellar Civilization like humans.

It was only about 5 million years after the final high evolution of the earth that the most terrifying creature on earth appeared.

It took only 2 million years of evolution to occupy the top of the highest food chain on the entire earth. It also formed its own complete planetary interstellar wisdom system and civilization.

It has escaped the ethnic group of ordinary creatures and wild animals. Until now, the human expeditionary force has begun to sweep the periphery of the Milky Way.

So it means that the earth spent 4 billion years to complete the early stages of its life-raising, any work. From 4.1 billion years, the earth has gradually become micro-life.

By the Cambrian era, life on Earth exploded, which took about 3400 million years.

And this is completely created by natural phenomena in the interstellar universe, which is simply a magical craft. There are many chances and coincidences here. Without these chances, all kinds of life would not have been born on the earth, and there would not be the final ultimate life.

, humans.

It is because ice-shaped comets and asteroids brought in space that hit the Earth, forming the early oceans of the Earth.

Moreover, in the era when the earth was formed, there were abundant water source structures around the earth, and these asteroid cloud belts were constantly launching towards the earth, making their own ice cubes.

It's like someone has arranged the amount of water and ocean area required by the earth long ago, which is just right. If there are too many, the territorial area on the surface of the earth will be greatly reduced, which is not conducive to the last higher life forms

Birth.

If there is too little water source, it will affect the reproduction of green living organisms on the earth and ordinary organisms. It will play a more arrogant role in the final birth of human beings.

Lin Dong is now at a 300 light-year position in this sagged space. He needs to use the system formed by stars to advance the fifth planet to his livable development stage as quickly as possible.

This requires Lin Dong to shorten the natural evolution of the earth's 4 billion years to hundreds or tens of thousands of years in a short period of time.

Moreover, Lin Dong must find a way to prepare in the distant air for the corresponding conditions for the formation of the earth. Of course, it is necessary to create this future livable planet according to the environment formed by the earth.

However, one feature of this galaxy is that its asteroid isolation belt does not have many cosmic ice fragments like the early days of the earth's formation.

The content of his cosmic ice fragments is obviously insufficient to the solar system, and there are still isolation zones between inner and alien planets.

The abundant ice water source contained in it. The water source on the earth does not come from the earth itself. After the earth forms its inner core and has a large amount of face, there is no water source on the surface. It is all based on ice carried by foreign comets.

After hitting the earth, it evaporates into the atmosphere, and finally the atmosphere recharges the water source on these surfaces to the ground.

Some are pure large and super large ice celestial bodies. These super large ice cubes with various life elements, and the celestial bodies directly hit seas like the Pacific Ocean.

The original Pacific Ocean was also a vast land during its early journey, with mountains, mountains and plains on it.

Like the Mariana Trench explored by humans in the Pacific Ocean, its depth exceeds 30,000 meters.

In other words, this trench used to be a peak with a height of 30,000 meters above the earth's crust. There was a long and narrow crack in the middle, and the canyon was surrounded by high and uplifting mountains.

It is likely that the impact of large ice celestial bodies caused this entire land to be submerged by the entire ocean.

Because the temperature on the earth was very high at that time, it could even reach more than 100 degrees Celsius.

These large ice cubes reach the ground and at their original location in the Pacific Ocean, a plain that is itself lower than the land.

In fact, judging from the Earth's satellite images, the angle of this plain is lower than the altitude of the existing land, at least more than 500 meters.

Perhaps the large ice celestial bodies at that time first collided with this large open area, forming a strolling ocean here.

Moreover, during the most primitive ocean itinerary, a large amount of steam rose into space, that is, the Earth's low-Earth orbit space, forming an additional 20 kilometers of space inside the 100-kilometer atmosphere.

Coupled with the sun's illumination movement and the journey of surface temperature, these water molecules in the sky form huge clouds, constantly ejecting downwards, and a large amount of water sources.

In the end, a large amount of water will flood the original Pacific Ocean, a large area of ​​plain with low latitude and low altitude angle.

The two huge mountains are a gully themselves, and it is very likely that this gully is the crack that hit the large ice celestial body back then.

Just like the Great East African Rift Valley on Africa, the vast Pacific Ocean finally formed. According to the flow of liquid molecules, the Pacific Ocean will continue to expand to four sides of southeast, west and north.

At this stage, the earth is still falling, ice and comets flying from the asteroids.

They bring a large amount of fresh water models, and there are many substances that form life, including amino acids.

Eventually, these ice cubes landed on the ground, making other areas with lower lyings become oceans.

The initial land on Earth was just a large area of ​​land that was combined together. It was called the Mu Continent at that time. From the itinerary of the Mu Continent, it can be seen that the ocean on Earth did not come from the Earth itself, nor did it rely on it.

The only water circulation system is irrigation.

This is entirely the accumulation of water surface caused by various comet ice meteorites in outer space. It then submerged all the low-altitude plains on the earth and sank these plains deep into the sea bottom.

The M continent that can be exposed on the ground later caused the complete plate division of the M continent due to the movement of the earth's crust.

With the continuous push of ocean currents, these split roads scattered to all sides of the earth's surface.

This is formed, today we see the land on the surface of the earth surrounded by the ocean.

The oceans on Earth are also an important way for the Earth's oxygen and water circulation system. There are also some ice cubes in outer space that are not exposed to the plains. Liu Xing and others hit the high and high M continents.

This forms rivers and lakes above the M continent, and then attacks glaciers based on the drift movement of the continental plates.

Various branches of freshwater sources were formed on the entire continent of the earth. Since there was not too much vegetation covering the earth at that time, these sources of water penetrated into the earth's underground along the surface of the earth.

A large amount of groundwater sources were formed, and the soil on the surface of the earth was very thin at that time, so it was easy for these frozen water sources to penetrate into it.

In this way, the earth creates various living environments suitable for the activities of human living bodies.

The most important environment is fresh water on the earth's land. There are also some sayings that some fresh water is caused by the infiltration of the ocean, filtering the toxic and harmful salts inside into the deep soil of the earth, and finally reverse osmosis.

Lin Dong is now performing the work of the birth of the earth's environment on the fifth planet. He will definitely not wait until this planet will take another 4 billion years to form the earth's water and oxygen cycles.

Now Lin Dong is using manual interference. In addition to his super engineering mothership of the Third Academy, Lin Dong has transferred all the 20,000 super-large engineering motherships carried by his fleet.

According to the 41-year environmental simulation of the earth, this environment is analyzed using a central system for data. The generation of this environment is formed into a data system, allowing one's 20,000 engineering motherships to complete these tasks.

It is expected that the peripheral formation environment that the earth has reached in 41 years is initially formed in about 100 years.

This requires many steps, including mixing liquid gas under the crust of the fifth planet into water vapor. In particular, some ice cubes need to be allocated from other regions.

The meteorite crashes into this planet, allowing it to fall naturally. It is born according to the birth mode of the earth's water source, the water source here.

So soon Lin Dong established a system here that completely simulated the environment formed by the earth for 4 billion years.

Since this planet is a true teenager planet, its crust is very frequent. It is like children's cells develop and reproduce several times faster than adults during their growth.

As the crust of this planet continues to move, the crust is also rotating on its own, forming its own unique earth porcelain environment.

This is the most standard method of forming a habitable planet. Without a circulating geomagnetic environment, it cannot firmly generate gravity and gravity, and it cannot absorb the ocean and the atmosphere.
