In the sky, a red planet is getting bigger and brighter.

This planet is the red giant that is only 49 million kilometers away from Blue Mercury.

In half a month, the red giant will reach the closest point in its orbit to Blue Mercury, a scenario astronomers say will occur once in 70 years.

The distance between the barren star and Blue Mercury has also shrunk to less than 2.8 million kilometers.

"After a while, the barren star, the blue mercury, the red giant, and the star will be in a straight line, and the tidal forces will increase, and there may be unpredictable changes, and even the wave height of the recent waves will increase a lot," the astronomer stressed. ”

"Blue Mercury is now the end of the world, and the unpredictable situation is just a little more complete in the end, rest assured, no matter what happens, I will rush back to deal with it as soon as possible."

After the successful test flight of Starlight, Tianming plans to take a group of people to the Red Giant Star to investigate again, where to stay for a period of time, build a fixed large-scale alien base, and send a team of 500-1000 scientists to stay in the Red Giant for a long time.

Tianming is going to develop the red giant.

It's not because he likes the resources of the red giant, but because Blue Mercury is all seawater, which is not very convenient.

When it comes to Blue Mercury experts, some people still have a strong seasickness reaction even if they live in the largest and most stable sea city, and they can't adapt to it.

In addition, after a while, the fleet will have a great migration from north to south, trouble, he considered, if he can, build a huge base in the red giant, transfer some ships and people there, and live there for a long time, which can save some migration work.

But before that. He also needs to go to the red superstar.

……

April 15th.

Two days after the successful test flight of the Starlight, Tianming took the original team from a few days ago, replenished a large number of supplies, took two space gates, and set off for Red Giant.

With a straight-line distance of 49 million kilometers, even if the Starlight ran at a speed of 100 km/s, it would take six days and six nights to arrive, and in order to save time, Tianming increased the speed of the Starlight to 200 km/s, which took only three days. He rushed from Blue Mercury to Red Giant.

The Starlight landing area was a flat col, and everyone walked out of the starship hatch wearing thick spacesuits.

The surface of the planet was barren, and the dark red dust reached the surface of the feet. The air is thin and the gravitational coefficient is about the same as that of Blue Mercury, but slightly smaller, with a look of 10.18.

Tianming and Lan Luo are not here for the first time, and they are not particularly curious about the red giant. "Oh, oh, oh" Cheng Dong was very excited. Running around with a step, smoke and dust billowed up. The Blue Star people in small spacesuits huddled into a pile and turned their heads to each other. Sometimes he looked at the red giant star at his feet in surprise, and sometimes pointed to the blue planet in the distance and gestured excitedly: "That's our home, where we came!" ”

"Okay Cheng Dong, stop playing. Come with me to the base. ”

It is not very convenient to speak in a spacesuit, and the atmospheric pressure of a red giant star is only 30% of that of the Earth, and the effect of conducting sound is weak. shouted several words before calling back Cheng Dong, who had run a distance.

The place where the Starlight docked, not far from the place where Tianming came to investigate last time, he also built a base, called "Red Bay Base", this base is still there, walk 500 meters forward to arrive.

On the surface of the red giant, there are quite a few topographical structures that resemble lunar craters – all the result of space meteorite impacts, some craters are more than hundreds of kilometers in diameter. This kind of impact is very frequent, if you enter the night of the red giant, you can see that there are at least thousands of meteors in a night, and the movement of individual meteorites hitting the star table can be sensed if you are nearby.

The Red Bay base is still well preserved, and there are no traces of meteorite impact, and Tianming breathes a sigh of relief.

The Hongwan base is actually a large tempered glass enclosure, which is covered with a number of sealed panel houses, with solar power generation devices on top of the board houses, as well as air supply systems and some living facilities.

Tianming evacuated all the air in the base, replenished the fresh air compressed in the abnormal space, and after reaching the standard air pressure, he took off his spacesuit, opened the door of the board room, and beckoned the earthlings and blue stars to enter the board room.

"Brother Ming, this base is so small, are we going to spend a while in this base?" Cheng Dong sat on a stool and said.

The standard of the Hongwan base was built according to the standard of accommodating 2 or 30 people, and suddenly more than 300 people came in, which naturally seemed very crowded, and some people did not even have a place to sit.

"No, you guys will rest here for a while, and then I'll open a new base, which will be much bigger."

Tianming found that less than 50 kilometers away from Hongwan, there was a tall mountain range, and the altitude of the mountain range should be more than 3,000 meters, stretching for more than 1,000 kilometers.

The mountain range is not very steep, the slope is gentle, and from the air, the mountain looks like a straight "".

Tianming plans to hollow out the mountain and build a huge underground base in this embankment.

There are many meteorites around the red giant, and it is not safe to establish a research base on the ground, and if it is hit by a high-speed meteorite, it will be a very dangerous consequence.

If the base is built in the interior of a mountain hundreds of meters or thousands of meters deep, the threat is much smaller, it is very safe, and it can also save a lot of construction work.

"You guys have a good rest here, I'll go back as soon as I go." After saying hello to everyone, Tianming changed into a spacesuit, and a teleportation flashed to the foot of the mountain range.

Looking at the tall mountain range in front of you, in addition to the surface covered with a light layer of dark red soil, the interior is all hard rock, light brown granite, the structure is dense, the texture is hard, and it should be very strong to carve out a base inside this rock.

Work begins.

Tianming first chose a relatively gentle hillside, extended the ability space, framed an area of about 100,000 square meters, a height of about 20 meters, and a volume of 2 million cubic meters.

The base of 100,000 square meters is almost the limit of the elevated volume of a mountain, and if it is excavated again, it is difficult to ensure that the mountain in the upper part of the inner space will not collapse, and Tianming will not expand.

But. A base of 100,000 square meters cannot satisfy Tianming's appetite, and the base he needs must be large and magnificent enough!

The direction of the mountain range is north-south, so he began to expand north-south, using the first base space as the base point, advancing 1 kilometer north along the interior of the mountain range, digging a tunnel, and then opening up a second base space - one at intervals like building a subway and a subway platform. After a while, Tianming excavated 10 base spaces with an area of 100,000 cubic meters.

"10 base spaces, with a total area of 1 square kilometer, are enough to accommodate tens of thousands of people to work in them at the same time, which is enough for the time being." Tianming muttered to himself.

The base is closed, there is no light, nothing can be seen, Tianming came out with a set of lighting equipment, and 2kw of industrial electric lights illuminated the space within 500 meters.

There is no air inside the base yet. The only outlet, Tianming had blocked in order to prevent external gases from escaping, and Tianming began to replenish the air again.

Ability space stored compressed air. There are 10 million cubic meters, all in a liquid state, and Tianming replenishes the base space, after reaching the standard air pressure state. Less than 500,000 cubic meters of compressed air were used.

Moreover, Tianming brought the door to the earth's space, and there were not enough resources such as air and water. You can go to the earth at any time to replenish, which is very convenient.

Looking at the time, two hours had passed, clapping his hands, flashing out of the base.

Stand at the top of the mountain.

Tianming glanced at the mountain range under his feet, and suddenly saw the star rising from the west, a strong red light swept by, and the piercing Tianming narrowed his eyes, and his heart was shocked, the sun hit the west and came out?

The sunlight shone on the earth and mountains, although it was desolate, but the special cosmic landscape still made Tianming stop and look at it for a long time.

"To the west is an endless plain, to the east is a low-lying basin, and the mountain range is like a bank in between. And this base at my feet might as well be called 'Red Bank'? ”

Red Bank Base, this is the name of an image that Tianming gave to the base in this mountain.

……

Back at the Red Bay base, Tianming brought everyone and equipment, including the Starlight starship, to the Red Bank base.

"This base is so dark, there's only one light."

"The ground is so flat, it's like a mirror, and it's a little slippery to walk on it."

"It's not good, I'm going to the toilet, Brother Ming, I just ate too much and want to go to the toilet now." Cheng Dong clutched his stomach that kept gurgling.

"Give you a flashlight, give you a box, and you go to a place where no one else can see to solve it." Tianming took out two things from the ability space.

"It's too dark, I'm a little scared alone."

Tianming called an expert to accompany him.

It took three days, everyone worked hard, and the space of Base 1 was completely transformed.

Tianming painted a layer of white lime on the inner wall of this base space, and hung more than 2,000 electric bars on the top, and after the power was connected, Space 1 was filled with light.

The place where they live is a glass room with curtains, with a cover on the top, everyone sleeps on a single bed with a silver steel frame, and most of the time they eat ready-to-eat convenience food, except for the occasional fire-making stir-fry and cooking.

An absolutely closed environment is not suitable for long-term survival, first of all, the air quality is easy to become bad, even when you go to the toilet, the ammonia produced will become an air component, and the concentration will be unbearable over time. The other is the temperature, the temperature will rise slowly, and if no cooling measures are taken, it will be like living in a steamer, dry and hot.

Add to that all sorts of problems, and it's sure to become difficult to survive.

Expert Ren Chao said to Tianming: "Commander, we should bring in a set of ecosphere systems from the outside, plant some plants that can purify the air, including water circulation system, oxygen circulation system, energy system, and use computers to control the balance, so that people can work and live in this base for a long time." ”

Tianming frowned: "So, you still have to find a country to cooperate?" ”

"It's also possible to develop it yourself, but it will take a while...... And the state has something ready-made in its hands, and it can be used when it is used. ”

"Okay, I see."

Tianming went back to the base of the National Defense Six Shields.
