When it returned, the Moonlight adopted the ultra-high-speed mode, and the sailing speed once exceeded 3000km/s, so it took less than thirteen days for the Moonlight interstellar cruise ship to land at the anchoring airport of the red giant.

Combined with the time consumed by departure, the entire interstellar travel plan took a total of 37 days, which was a week longer than the expected 30 days.

However, the harvest is still huge, the use value of the Earth Yellow Star and the Silver Light Star is very large, and all the frozen stars are included in the ability space, and Tianming also gets enough water resources.

Back after Red Giant.

Tianming first brought the family back to the small space, and then came to Blue Mercury.

Beneath the pitch-black ocean floor of Blue Mercury's North Pole, there are thirty space portals that act as interstellar pumping machines, and they are still in operation.

"The current land size of Blue Mercury is estimated to be more than 60 million square kilometers, which is more than expected, and the height of the sea level has only dropped by about 65 meters, and if it really drops by more than 600 meters, the area of the land that has surfaced may be more than 150 million square kilometers......

"But 60 million square kilometers of land is definitely enough."

"And, for the sake of Blue Mercury's eco-environment, pumping work must also be stopped."

Tianming dived to the bottom of the sea, closed these spatial doors one by one, and collected them into the ability space.

I went to the cold seabed of the South Pole of Blue Mercury again, and the thirty space gates that were placed on the bottom of the Antarctic Sea also recovered the ability space.

Then close the space gate and the nuclear-powered pumping machine at the other end of the red giant and put it into the ability space...... In this way, Tianming suspended the work of pumping water from Blue Mercury to Red Giant.

Red giant.

On the east side of Hong'an Mountain, the waves are finally smaller.

The area of this sea is now more than 120 million square kilometers, with an average depth of more than 800 meters.

About 1.2 billion tonnes of water, minus the naturally volatile part. The water pumped from Blue Mercury is basically in this ocean.

Tianming decides to take out a large amount of ice from the ability space and drop it into the ocean to replenish water.

But there are still some problems.

Han Lei said: "This marine area was originally formed in a large crater, the crater area is 30 million square kilometers, the maximum depth is 11,000 meters, the average depth is 2,800 meters, and it can only hold less than 900 million tons of water at most, but with the increasing amount of seawater, the previous crater. It has been filled with seawater, and the excess sea water overflows, increasing the area of the ocean to 120 million square kilometers......"

"So, this sea, at best, is a shallow sea."

"If we replenish water resources to this shallow sea, the rising sea level will cross the Hong'an Mountains and submerge the plains of the New Shenzhou District 1...... It is very dangerous. ”

"You mean to say. Can't rehydrate this ocean anymore? Tianming's brows furrowed, "Then where do I put the water?" ”

"There are two ways."

"The first is to dig the trough deep and expand the volume of this ocean...... That's where you come in, Commander. The crust of the red giant is so thick that it doesn't matter if you dig a trough 100,000 meters deep, you just need to increase the average depth of this ocean to 10,000 meters, and you can cover an area of 120 million square kilometers. Hold all the seawater you need. ”

"The second, in the 35th region southwest of the red giant, also has a large crater that has been hit by a super-large meteorite. The area is larger than this crater, and it can hold about 3 times the amount of water in this ocean, so I asked you to put a lot of water in that crater to create a second ocean. ”

"The straight-line distance between these two oceans is more than 10,000 kilometers, one mostly in the northern hemisphere and the other mostly in the southern hemisphere, forming an approximately symmetrical distribution. In this way, the water vapor evaporated from the two seas every year can keep the entire red giant in a relatively humid environment, which can ensure abundant rainfall in most areas and reduce the storage of deserts. ”

"Commander, I will use the two methods at the same time, because the red giant still needs a lot of water resources, more than 10 billion tons of fresh water, and it must be accommodated by two seas with sufficient depth."

After listening to Han Lei, Tianming nodded: "Okay, just do as you say." ”

……

According to the planning plan formulated by the experts, Tianming began to work on the marine transformation of the red giant.

The sea on the eastern side of Hong'an Mountain, known as the "East China Sea", covers an area of 120 million square kilometers, has an average depth of 800 meters, and currently has a water storage capacity of 960 million cubic meters.

Tianming first wants to expand the capacity of the East China Sea.

Standing above the East China Sea, Tianming extended a divine consciousness force field and began to sense movement within a radius of 600 kilometers...... Of course, the main thing to perceive is the movement of the earth's crust on the seabed of the East China Sea.

Red giant is a rare semi-cold planet, the thickness of the earth's crust is more than 2,000 kilometers, the geological structure is very stable, earthquakes and volcanic eruptions rarely occur (at least not seen so far), this geological structure, determines that no matter how Tianming digs, as long as the crust is not dug through, the trough of the East China Sea is not a big problem of 30,000 meters, 50,000 meters, 100,000 meters.

However, experts from the Ministry of Planning have given the idea of digging a cone-shaped sea pit with an area of 50 million square kilometers and an average depth of about 10,000 meters in the central core area to hold enough water.

Standing in the middle of the planning area, Tianming extended the ability space, reached the rock crust, measured the thickness of the delineated rock, used the space barrier to close, and after breaking a large number of molecular chemical bonds, a giant stone with a volume of 3 million cubic kilometers entered the ability space.

Under the seabed, a large hole with a volume of 3 million cubic kilometers instantly appeared.

3 million cubic kilometers, equivalent to 3,000 trillion cubic meters of space, such a large hole space is enough to hold 3,000 trillion tons of seawater, which is about 1/30 of the total water storage in the East China Sea.

Thundered~~~

The sudden appearance of the large hole in Tongguò, a large amount of seawater poured in from all sides, making a deafening roar, and the huge whirlpool in the center was like a bottomless and terrifying cliff.

In the time that followed, more than a hundred such terrifying holes appeared, and finally joined together. A "deep-water lake" with an area of 50 million square kilometers has been formed.

The East China Sea, which previously covered an area of 120 million square kilometers, has now experienced widespread low tides, and the sea water has disappeared, and the previously submerged area is now exposed to everyone in the form of a dry seabed.

The staff stationed at Red Bank Mountain were taken aback.

"What's going on? The sea is gone? ”

"Impossible, the water level of the sea was high two or three hours ago, why are there only a few small puddles left now?"

"Am I dazzled?"

"No, we have to make a big phone call and report to our superiors!"

……

Therefore, all the flowing sea water is concentrated behind this central trough, and I stand in the sky above and look down. The huge amount of seawater, which only fills less than a fifth of this trough, looks like a little water in a large bowl at the bottom of the bowl, and it is pitiful.

"Now that you've got the capacity, let's start putting ice cubes."

Tianming took out the ice cube taken from the frozen star in the ability space, in the four-dimensional space, and threw it into the "big bowl" under his feet.

Table tennis table tennis ...... Bang!

Rectangular cylinders of transparent ice. Like a piece of fries, it was thrown into the trough, making a sound similar to adding ice to a water glass.

The volume of this ice cube is 3 million cubic kilometers. Equivalent to 3,000 trillion tons of seawater. Tianming only threw more than a hundred of these ice cubes into the trough, and the entire central trough overflowed with seawater.

The temperature of this ice is very low, almost more than minus 200 degrees, after being thrown into the trough. The temperature around him plummeted by more than 50 degrees in an instant, and a large amount of white mist came out, and even Tianming, who threw ice cubes in the sky, could intuitively feel the coldness...... The sea was frozen. A layer of fine ice crystals also appeared on the outside of his protective suit.

"At present, the average daily temperature of the red giant is still relatively high, around 50 degrees, if the red giant is replenished with enough water, it can have a good cooling effect...... Moreover, if a large amount of ice is put into the red giant, this cooling effect will be more obvious, which can reduce the average temperature of the surface of the red giant by about 5-10 degrees in the short term and maintain it for a period of time. A climatologist said.

Therefore, after Tianming threw more than 100 ice cubes in the central trough, he dug more than 100 rectangular holes on the seabed with an area of more than 70 million square kilometers outside, and then laid more than 100 ice cubes into these large holes......

In this way, in total, there are nearly 7 billion tons of seawater stored in the East China Sea.

……

After getting rid of the East China Sea, Tianming went to the southwest, more than 10,000 kilometers away from the East China Sea, in another area - near a large meteorite crater.

The crater in front of me is indeed very large, or it can be said that it is the largest crater on the red giant, and it is dark and you can't see the low ...... It is estimated that it was smashed out by a super meteorite.

However, as a red giant star is about to become the second ocean, the West Sea, even though this meteorite has a diameter of more than 5,000 kilometers and an area of more than 30 million square kilometers, it is still a little unsightly...... The crater cannot hold more than five billion tons of seawater.

As in the case of the East China Sea, Tianming first excavated the foundation of this large crater downward and expanded outward, forming a central trough with an area of 50 million square kilometers and an average depth of 10,000 meters...... Then, within this central trough, thirty huge blocks of ice were dropped.

Of course, because there is no guarantee that the ice will melt at the bottom of the trough, Tianming did not put too much ice into the trough, but dug nearly 200 large pits around the trough, and then put 200 ice cubes in these large pits, and after the heat melts, the sea water will flow into the central trough.

…… In order to speed up the transformation of the planet and facilitate the water intake work of the development team, Tianming dug three large pits with an area of 90,000 square kilometers in the middle of each of the 32 districts of the New Shenzhou Continent, which has been divided in detail now, in the middle of each area, in an equilateral triangle distribution, with an average depth of 10,000 meters for each pit, so that each lake can accommodate 900,000 cubic kilometers of ice.

Thirty-two districts consumed nearly thirty pieces of ice.

Combined with the ice and seawater pumped in the East and West Seas, the total amount of water is close to 15 billion tons, which is more than the entire earth. The problem of water shortage of red giants has been completely solved.
