Chapter 542: Earth's Last Line of Defense

"Xu Lao, if you have any words, just say it! I don't know how to say this, it looks quite ..." Zhu Lan looked at Xu Dezheng with amusement.
Xu Dezheng froze and shook his head helplessly.
"Zhu Lan, I just want to know a question, you say, we really will face that?"
Zhu Lan sighed, "Did we already face it?"
Xu Dezheng was silent.
What Zhu Lan said was the war of the Yunhe civilization that occurred in the South Pacific. At that time, if it wasn't for the blue shot to destroy the wormhole, the earth may now be a colony of the Yunhe civilization. Was destroyed.
Xu De sighed deeply.
The earth is changing now, too fast! So many people can't get used to it.
"Actually, in the current situation, it is a good thing for the earth and human beings, isn't it?"
Xu Dezheng was silent.
Zhu Lan is right, because external threats, no matter what attitude they are in, the earth must guarantee the highest combat effectiveness, and absolutely must not consume any combat effectiveness again in the internal struggle.
The establishment of the Pale Blue Agreement is precisely to reach such a tacit understanding.
All the major countries in the world are all united. Although everyone does not want such a union, in the sense of humanity, even if you don't want it, you must also unite.
If there was a state resistance, others would not mind erasing the state ’s power and replacing it with a new one. Even the most powerful United States in this opposing country may implement it.
Although the United States is strong, the United States is not enough if it faces mainstream countries around the world.
The pale blue agreement made the current situation.
Environment changes, governance comes into being, human liberation is officially released, and virtual games have turned the world's turmoil from reality to the virtual world.
Robots have released all the productivity of the world.
With the development of the space industry, the whole world has set its sights from the shallows of the earth to space.
The formal development of lunar resources has enabled all countries to increase the development of space.
Especially now that the detection of the earth and the moon within 500,000 kilometers has directly enriched many of the earth's resources.
The Blue Colony Star project, which began last month, no longer places humans on the moon alone.
The completion of the orbital elevators in the Atlantic Ocean, sharing the traffic volume of the South China Sea orbital elevators, the western countries began to formally exert their forces.
In addition, after the transfer of fantasy manufacturing to the moon, the construction progress of the Tamron-class transport spacecraft was very fast.
It took half a month from the beginning to take off a ship, and now it is almost three ships a day off the line Hello.
.
The earth includes blue, the number of Tamron-class transport spacecraft has exceeded 700, and the huge transportation volume has directly made the moon bases, space ports, etc. of all countries progress rapidly.
"I have now started planning for the expansion of the Great Wall Space Port. As you know, I have rejected the construction of space ports around the world by other countries!"
Xu Dezheng nodded silently. "We know this and they understand it, so they don't say anything!"

Yeah! Too many spaceports around the earth are not a good thing. There is an alien force on the earth that will be able to swell organically. The earth only needs one spaceport. It is enough. At present I have started to plan the earth Finally the cordon exists! "
Xu Dezhen frowned. "Is it too fast?"
What is the last cordon of the earth? Xu Dezheng understands that many countries understand that because this concept was proposed after the Pale Blue Agreement, but at that time, the concept was shelved for various reasons, and now, Zhu Lan raised it again, and Xu Dezheng was condensed. .
The last line of defense, that is, the earth's last line of defense.
It is estimated that within 100,000 kilometers, there must be no space station, that is to say, in addition to satellites, within 100,000 kilometers of the earth's center, there can only be the Great Wall Space Port, and in the future, The Great Wall Space Port will be a huge ring that surrounds the entire earth.
Four orbital elevators connecting the earth.
Once this construction is completed, within 100,000 kilometers, no other spacecraft except the United Earth Fleet can approach this area. This is the existence of the Earth ’s last cordon.
In the future, all warships must be 100,000 kilometers away from the earth.
And more are 500,000 kilometers away.
The last line of defense of the earth is half a million kilometers.
And this includes the moon.
This is the existence of the defensive line of the solar system that Zhulan established early.
The defensive front of the solar system has planned a total of nine lines, and now, it is planning the deepest, which is the last line of defense of the earth, and the second line of defense will be above Mars.
This is why Zhulan began the mission to Mars.
"The emergence of the Glorious Freedom Confederation represents that we have begun to formally come into contact with alien civilizations. Except for the previous Yunhe civilization, the earth must have enough power to defend itself. Some things must also be planned!"
Xu Dezheng naturally understood the meaning of Zhu Lan, but this plan is simple to say, but how difficult it is to do, I am afraid no one knows.
After all, the earth has more than 200 countries.
Ding ~~
The train arrived in Azure City, and Xu De was looking out.
Huge dome, transparent to see the earth in the distance.
A large number of engineering robots and engineering equipment, with human assistance, began to do the final cleanup.
Zhu Lan went out.
Xu Dezheng followed.
The arrival of Zhu Lan, no one was notified of the loss, naturally no one knew the arrival of Zhu Lan.
Standing in front of the blue city station, looking at the blue city, Zhu Lan suppressed the excitement in his heart.
"If you do n’t see it with your own eyes, it ’s really hard to believe that an urbanization was built in less than half a year.
!! "
Xu Dezheng is also impressed. Although he has been here many times, every time it is very shocking.
All the construction of the Azure City is modular, and it is directly taken from the moon itself. By manufacturing some building modules, it is transported here and built directly.
As long as all the modules are in place, a 30-story building can be built in only five to eight hours, and the speed of the building is simply terrible.
Because all the construction is a robot, there is no safety precaution. One module has not yet been fixed, and the second module is directly installed.
Then the robot enters the module and uses a huge steel frame to fix it all.
The azure city has 1.67 million construction robots, which complete the construction, decoration, road construction, forest greening and so on of the building.
After the Pale Blue Agreement, Pale Blue no longer needs to be hidden, and a lot of plants suitable for the growth of the moon have been transported directly in many virgin forests. Through gene cultivation, a large number of plants have been planted on the earth, and the soil in which the plants are planted is genetically modified. Optimized, transported to the moon, all the plants on the moon are transported directly from the earth.
Wei Lancheng has several small parks. These parks can be regarded as the existence of a community in any city on the earth, but on the moon, it is a very shocking feat.
The biggest scenery of the Azure City is a 3,400-meter-wide lake in the middle of the Azure City. The King Kong transported a large amount of ice directly from the Antarctica into this lake, causing the existence of the first artificial lake on the moon, and in the lake The existence of a circular park on the side will be a star embellishment in Azure City!
Azure City is a semi-inlaid city, which is a pit in itself. Canglan penetrates it here through engineering machines to form a huge pit with a diameter of 12 kilometers. This is the main body of Azure City.
Construction started directly in the pit, and a huge protective cover was built around the large pit to protect the city's existence, and there is a five-kilometer-long solar conversion device on the side of the protective cover, they will Convert solar energy into electricity for use in Azure City.
Azure City's protective cover is transparent. It looks like there is only one layer. In fact, it consists of five different protective layers ~ EbookFREE.me ~ The innermost is to prevent the diarrhea of ​​oxygen, and the outer three Water chestnut insulation layer, they can cut off the ultraviolet rays of the sun, and it becomes a tolerable level, and because of the water chestnut, the light of the sun can shine to 80% of the blue city. In this way, even the blue Many of the cities are underground and can be shone by the sun.
Zhu Lan has more advanced technologies, such as the atmospheric simulation technology in Bliss Space.
If you use such technology, you can build the city directly, without the need for a protective cover. You only need to build an atmosphere manufacturing device around the city, which will create an atmosphere directly above the city and cut off the oxygen. And can eliminate the sun's ultraviolet rays.
But such a technology is too scary, Zhu Lan did not dare to come up with it.
There is this construction on the Colonial Star Project No. 188 of the Blue Colonial Star. It will be the headquarters of the future Blue. It will be built 490,000 kilometers away from the moon, where it is completely off the earth ’s last line of defense. Existing. The project of the blue colony star has not been carried out until the 7th colony star. It is still far away from 188, and the problems now facing, Zhu Lan is not in the mood to build the blue headquarters.
"The Blue City has six urban areas, and the construction of two urban areas has been completed. Theoretically, the Blue City is ready for use!"
Xu Dezheng nodded. Many countries have purchased a piece of land from the blue to build a blue city. After all, there is only a city in the blue city. After all, there is no way to build a consulate to the base. So, If other countries want to go, the situation of that base may not be fully exposed. For this reason, choosing the blue city is the best choice! (To be continued.)
