Xu Xingchen took his wife and children to the cafeteria for dinner, and in the afternoon we visited the environmental renovation site here.

After the ship girl arrived at Planet 4, she continued to maintain and increase the original environmental transformation range and began to implement a new environmental transformation plan - direct deicing.

The core direction of Planet IV’s environmental transformation is always to increase the overall temperature of the planet.

However, increasing the temperature will cause the ice sheet to melt. When the ice sheet melts, it absorbs heat from the air, which will cause the surrounding environment to cool down.

A large part of the heat provided by the original plan to the planet's atmosphere is absorbed by the ice cap, causing the planet to heat up slowly.

At the same time, the melting of massive ice will also cause the sea level to continue to rise.

After the end of the last ice age of the earth, a large number of glaciers melted, directly causing sea levels to rise by more than 100 meters and the coastline to retreat significantly.

The volume of the ice cap covering the world is at least one order of magnitude higher than the volume of glaciers during the Earth's ice age.

If all the ice sheets melt, the sea level of Planet IV could rise by 300 to 500 meters.

Under normal circumstances, the ship girls' military ports, bases, and cities will be built in coastal areas.

If sea levels are allowed to rise, either build the military port on a mountain top several hundred meters high, or give up the coastline and build a city inland...

In response to this situation, the ship girls planned and prepared two plans to prevent the ice from continuing to absorb heat and reduce the ice to directly melt into seawater.

The first is to build more resource conversion equipment, directly convert ice into resources, and store them in warehouses in military ports and space bases.

Then, find a way to get the ice cubes out of the planet and into space, and it is best to pile them up in space and turn them into ice satellites.

Slightly plan the arrangement and angle of the ice satellites, use the ice surface to reflect more sunlight to the planet's surface, and in turn heat the planet.

This plan can be said to kill two birds with one stone, but when the question arises, how can we send a large amount of ice into space?

The scientific research ship girls designed two plans.

First, throw it out.

Build a large movable energy projection device to continuously chop and collect ice cubes, and directly accelerate to project into space.

After these devices are built, they can basically be automatically moved and worked. The ship girls only need to plan the ice-picking route.

However, this device is mainly used in plain areas on land. In mountainous areas with complex terrain, a large number of ship girls need to cooperate to work, and it is not suitable for the ocean with thin ice.

In response to the ice in these areas, the ship girls built a large number of lakes or reservoirs based on the surrounding terrain in advance, so that the melt water can gather into the inner lake and sea, rather than flowing directly into the sea.

Then ship it out.

A group of ship girls were organized to replace specially designed semi-submersible flat-panel transport ship hulls and ship ice to space for abandonment.

This method can only be used at sea or coastal areas, because the ship girl cannot unfold the hull on land.

The volume of ice on the planet 4 ocean is about 9.18 million cubic kilometers, or 9180 trillion cubic meters.

A part of the two poles ice sea areas can be left, but it is relatively limited, and most of them have to be thrown out.

The specially designed transportation hull has a capacity of about 640,000 cubic meters, which theoretically requires more than 14 billion times to be transported.

However, the hull of the transport ship is actually a semi-submersible floating dock, and the structure is a square box that is almost cube-shaped. The surrounding panels can be disassembled, so there is no need to cut the ice cap and then slowly load it onto the ship.

After the transport ship unfolds the hull, the tail of the hull can sink directly under the water and then penetrate under the ice.

At this time, the ship girl who was helping around used a machine to cut off the ice cube on the ship girl's hull from the surrounding large ice caps, and the transport ship controlled the hull and then floated up.

A whole piece of ice that is hundreds of thousands of cubic meters was shipped directly, and the whole process took less than two hours.

After the transport ship is shipped, it will return to its status as a ship girl. It will take a space transport plane together and push the ice on the booked orbit and return to the ground.

In this way, the entire shipping process is less than three hours, and a transport ship girl can run two to three trips a day.

There are 50,000 transport ship girls, who can transport more than 100,000 times a day, and can be transported in about thirty-five years.

The number of subsequent transport girls will continue to increase. If 500,000 girls are transferred, they will be able to complete the transportation in more than three years.

In the days that followed, Xu Xingchen stayed on Planet 4 most of the time, returning to his parent planet every six months, but he would leave after only half a month.

Then go to Planet 2 to express condolences, and then go back to Planet 4 again. This cycle takes about a year.

The parent planet continues to transform the remaining deep seas, accelerates the construction and transformation of more space transport ships, and continuously delivers ships, materials, and population to planets 2 and 4.

Five years have passed in a blink of an eye. When the spring of the new year comes, Xu Xingchen sat in the office of Planet IV Capital and checked the entire alliance again.

The alliance's deep sea has been completely transformed, and the ocean of the parent star has not been born for more than two years. At this time, the total number of deep seas in the alliance is 1.28 million.

The total number of the head of the ship girl also slightly increased to 1.32 million, mainly the soul core reserved by the original ship girl organization, and it became a native ship girl through construction.

Xu Xingchen himself continued to build and finally built all the native Chinese ships, including the Type 003 aircraft carrier, Type 075 amphibious assault ship, etc.

With the deep sea transformation and the native ship girl, the total number of ship girls in the entire alliance reached 2.6 million.

Among them, the number of ship girls left behind by the parent planet is 1.2 million, the lunar base is 100,000, the second planet, and the fourth planet is 800,000.

The human population under the notice from the alliance also completed an accurate statistics, totaling about 105 million.

Most of them are in the parent planet, with planet 2 immigrating 1.6 million and planet 4 immigrating 3.2 million.

The ship girl and human race of the two planets have been greatly improved, which has also accelerated the speed of planetary environment transformation.

The regional scale of the renovation in the last two years is far greater than the scale of the renovation in the past five years.

So much so that the planet IV, which has a larger surface area and a more complete start, but has a larger population, is basically the same as the planet II's transformation progress at the end.

After nearly ten years of transformation, the environmental transformation of the two planets 2 and 4 has entered the final stage.

The adjustment of atmospheric composition has been completed, and the greenhouse effect intensity and atmospheric pressure intensity have been adjusted to the standards similar to the Earth and the ship's mother star, and the oxygen content of the air is slightly higher than that of the mother star.

In the tropical areas around the equator, the temperature has approached 30 degrees in summer and 20 degrees in winter.

Such temperatures no longer require special insulation, so the environmental heating device here began to be gradually shut down and removed two years ago.

In temperate areas in the mid-latitude, the temperature in most areas has exceeded 20 degrees in summer and around minus 20 degrees in winter.

The heating devices in the mid-latitude areas will be gradually shut down this summer, but will be retained for winter heating.

In the cold zones of high latitudes, the temperature in summer is around minus 10 degrees Celsius and in winter is minus 50 degrees Celsius.

This overall climate is already suitable for human survival. Although the temperature in the cold zone is harsh, it is originally planned to retain glaciers.

The marine ice sheets in the middle and low latitude areas and the ice sheets in the plains and plateaus have all been removed and sent to space, forming two giant ice arrays in space.

Their reflected sunlight makes Planet 4 as bright as the nights during the day, and they can live without turning on the lights.

These ice array satellites have effectively increased the temperature of Planet 4 and are now slightly adjusting the angle to heat the temperate areas of the hemisphere in winter.

Next year, the winter temperature in the central temperate zone will increase to around minus 10 degrees Celsius.

In the next three to five years, the ambient temperature will continue to rise until it basically ties the Earth and the ship's mother planet.

In this continuous heating process, many glaciers naturally melted, and the ocean finally received a large amount of water replenishment.

So in order to maintain sea level, the ship girls not only sent ice to space but also sent a lot of water to space after the ship girls were abundant...

Now, in the space orbit of Planet 4, the water resources of the two ice arrays have exceeded 100 million cubic kilometers, which is about one-thirteenth of the total water volume of the earth.

At the same time, the ice sheet covering the entire planet melted rapidly, which would have formed a large number of ice and snow melting rivers and lakes.

With the planned cooperation of the ship girls, the number and scale of these rivers and lakes have soared many times compared to normal.

The rivers on the plain gather in melt water and flow naturally along the terrain. They are originally very shallow, with very wide water surfaces and crisscrossing.

Lakes of all sizes are scattered among them, perfectly blending with the wide and dense river network. Many areas cannot tell which rivers are and which lakes are.

The deep inland and mountainous areas have formed more giant inland lakes between mountains and valleys, with their absolute geographical advantages.

Inside the large-scale mountains, a large number of deep and rapid rivers formed, connecting these large households to form an extremely rich inland water system.

The extremely abundant water resources in the inland areas make it moist enough inland where it is difficult to obtain marine water vapor, making it easier to deploy vegetation plants that can grow rapidly.

In the end, the formation of large-scale desert Gobi climate was basically avoided.

Compared with the "immediate results" of Planet IV, the environmental transformation of Planet II is a bit "ink mark", mainly because the cooling is not as fast as the temperature rises.

The atmospheric composition adjustment has been completed, but the average temperature on the planet's surface is just below the 40-degree line, and then it will continue to drop below 30-degree in the next two or three years.

In the next ten to twenty years, it will gradually decrease to below 20 degrees, and finally basically stabilize in the range of 16 to 18 degrees, still slightly higher than the 15 degrees of the earth.

At this time, the summer temperature in the Arctic region has dropped to 20 degrees, and the winter temperature has dropped to around minus 10 degrees.

Therefore, the ship girls no longer need to cool down specifically in summer in the dome base of the Arctic, but instead start heating in winter.

As for the mid-latitude temperate areas of Planet II, the current climate is basically the same as the tropical areas of the earth.

The low-latitude tropical region of Planet II has now become the last natural hot spring world.

The air pressure around the world has been basically even, and vegetation coverage has been basically completed.

In the past decade, Planet II has undergone gradual environmental transformation, resulting in frequent air pressure differences at different latitudes around the world.

This has caused super-strong global air convection and formed a persistent and extremely strong global storm.

When the global air pressure is uniform, this persistent catastrophic storm is rapidly regressing to normal levels.
