When the Iceman space warship will be out, a metal sky curtain is slowly rising from the star-studded buildings on the plain, and soon the space inside the entire bubble will be covered.

Inside, the metal skylight is rising, with 12 trails, reducing the entire bubble space to a height of 20 meters.

At the same time, there are also huge new material-built pillars inside, rising further from some giant platforms.

These giant pillars total a total of 108, after calculation, can perfectly support the huge metal sky.With the characteristics of new supermagnetic building materials, there is no need to worry about the collapse of the event.

In order to be beautiful, around these giant pillars, there will also be various buildings built, so that people on the ground will not be affected by the giant pillars, resulting in a certain sense of repression.

Originally, when Li Chunfeng formulated the plan for excavating alien warships, he thought that he would build an underwater city and a city covered in a metal screen.

Between each layer of metal cover, there are many repulsive output points, which is equivalent to 12 invisible repulsion barriers in the subsea city to ensure that the seawater will never be inverted.

At the same time, this metal screen cover has a strong protective effect, each one has a thickness of one meter, 12 superimposed, and even a million tons of nuclear weapons explosion, as long as it is not a positive hit, just a shock wave, it can not destroy it.

Moreover, Li Chunfeng, who has various means of offensive defense, will not let people drop nuclear bombs here.In space alone, a number of space-based supermagnetic particle guns and electromagnetic rail guns have been arranged.

For more than a month, Li Chunfeng has not only deployed a satellite network in Earth's orbit, but also deployed some space-based weapons to ensure that his base will not be hit by long-range ballistic missiles, especially missiles with nuclear warheads.

After more than a month of complete ecological circle experiments in Hai'an Town, a complete ecological circle will also be built in this new submarine city.

Humans can live here freely.

With the close of the metal shield, outside the 12 metal shields, a new electromagnetic shield was excited again, which was learned from the ice man's space warship technology.

With it, the effectiveness of nuclear weapons attacks is once again greatly reduced, and in order to break through its protection, it is necessary to exhaust its energy first.

However, at the Tianfeng II underground base, the newly built cold fusion reactor tower provides a steady stream of energy for this shield, and will add a new cold fusion reactor to ensure the energy supply of the entire metal shield.

On the metal shield of the entire submarine city, there are multiple entrances and exits for "high wind" flying saucers to enter, at this time, Li Chunfeng controls the "high wind" flying in from an entrance.

Just entered the seafloor urban space, the sky curtain of the metal shield is gradually brightening up, and a round of artificial sun follows a certain orbit and slowly rises into mid-air.

The whole space suddenly brightly, and at this moment, a behemoth slowly rises in the huge black hole.

The rugged figure, blocking a large part of the area of artificial sunlight, the ice man's warships have no anti-gravity device, their warships are built in the space factory.

Battleships that can take off directly from the surface of the planet are generally small and medium-sized space warships at the destroyer level, relying entirely on a powerful power engine to get rid of the planet's gravity.

Large warships generally do not fall on the surface of the planet, because when they take off again, it is too waste of energy, and usually there is no need.

Li Chunfeng has carried out a major transformation of the warship, not only equipped with the anti-gravity Serre engine, but also added the holographic visual stealth system.

Of course, the warship's main control computer has been replaced by a super-magnetic quantum server group, and No. 5 has also been upgraded to super artificial intelligence, because of the information of space warfare in the ice-mandated computer, No. 5 has naturally become Li Chunfeng's military director.

To this end, after Li Chunfeng himself digested and absorbed the military knowledge of the earth, he also passed it on to No. 5, so that he also had the most complete military knowledge base on the earth.

On the plains of the undersea city, a place was planned in advance for temporary berthing of warships.

At present, some of the modification work of space warships has not been completed, the most important is that when the space warship made the last space jump, the energy circuit of the battleship was damaged due to the one-time injection of the energy of the cold fusion reactor tower.

Although part of the restoration, and with the help of the modified Serl engine, the warship can fly out of the ground, because there is no base in space to repair it further, it can only be completed in the subsea city, and after comprehensive testing can fly back to space.

So after the Iceman warship flies, it will be moored here, waiting for a complete repair before taking off again and flying into space.

Looking at the space warship in space, Li Chunfeng was still a little excited, although he had seen it many times.

At this time, it is slowly landing to the mooring field, flying up the space warship and buried in the rock formation, it looks different.

Overlooking the space of the entire underwater city, at a height of 1000 meters, there is not much depression, "Heist" and the four-legged robot of the Iceman are grasping and filling the distant boulders into the huge black hole.

After all, the original place where the warship was located, there was hot lava about 100 meters below it.

Li Chunfeng does not want to cause the lava to spew out from here because of the lack of pressure here, so it is necessary to complete the backfilling work as soon as possible, and increase a certain weight to suppress the lava.

The previous preparations were also sufficient, and a large amount of rock had been dug up in the mountains from far away, and at this time it was just to landfill it.

As for the large copper mines and affiliated gold mines seen before, it is natural to take this opportunity to build a good collection hole and turn a large number of ores into raw materials.

Li Chunfeng did not expect that the high-grade gold reserves in this place actually reached 5,400 tons, if their own mining is completed, and smelted well, it is also a huge wealth.

It just doesn’t seem to be much use to yourself.

After the warship was stabilized, a hatch in the upper part was opened, and six ice man's space fighters flew out, surrounding Li Chunfeng's "high wind" flying saucer.

Iceman's space fighter compared to the "strong wind", can be described as their own advantages and disadvantages, ice man space fighter is a manned fighter, some of which are life-saviation equipment and anti-load equipment.

This is Li Chunfeng need to learn to use, because his "strong wind" currently has no such equipment, which is controlled by the brain, and is a robot variant.

Although the life-saving equipment of the Iceman is not suitable for human use on Earth, some design concepts are still useful, and the most useful is the load-resistant equipment.

As a nitrogen-based life, its load resistance is 1.5 times that of the Earth's human, and after using the load-resistant equipment, it can fully adapt to the requirements of interstellar combat.

The ice man's space fighter originally also had a drone version, but because the Iceman has not developed a real artificial intelligence, the intelligence level of its computer is almost worse than Li Chunfeng's weak artificial intelligence.

After many practical verifications, the drone has no advantage in the face of manned fighters, so it was abandoned by the Iceman.

In the ice man space fighter's main control computer, there is no reserve of too complete information, some ice man historical data, but also later in the ice living area of the personal computer obtained, but are either vague, or a piece of tape.

In general, I can only get a little understanding of the ice society and their technology system.

Their scientific and technological system is relatively single compared to the earth, and basically has the characteristics of low temperature.(Compared to Earthlings)

The overall scientific and technological progress is very slow, but in the field of electromagnetic progress is faster, followed by a qualitative leap, the ice man has early on low-temperature nuclear fusion technology, so earlier than the earth people to the starry sky.

In order to break away from the parent galaxy that is entering the period of decline, the ice man has a strong desire to expand outward, spreading for nearly 20 light years in just a few thousand years.

How can ice people without space-jumping technology expand to such a huge area of 20 light-years?

The answer is, wormholes!

In the records of the Iceman, there are multiple natural wormholes near their galaxies, through which they go to other galaxies.

The requirements and instructions for flying in the wormhole are detailed in the master computer, after all, for space cruisers, this is a compulsory course.

During thousands of years of starry skies, the Iceman also gained some of the technology of other civilizations, such as quantum communication technology and quantum theory.

These records are also the most confusing places for Li Chunfeng, after all, the scientific and technological development of the Ice Man and the scientific and technological development of some civilizations encountered are not as good as the earth.

It is necessary to know that the recorded history of human beings on Earth is only thousands of years, and the real scientific development is only more than 300 years, but the speed of scientific and technological development of human beings on Earth is simply equivalent to the speed of the universe for ice people and other alien civilizations.

Is there a special place for humans on Earth?Or are we encouraged by the more advanced alien civilizations?

Li Chunfeng, who did not understand, simply did not want to, but sent most of the four-legged robots on the space warship to work.

This underwater city should be completed as soon as possible, with this steel fortress-like city, Li Chunfeng at least do not have to worry about being M-country mushrooms.

For the old M will carry out the "defender" military exercises, Li Chunfeng has learned from his military network, is a combat operation against the so-called aliens.

However, the old M's movement is not fast, and it is still in the gathering before the exercise in country A.

Just Li Chunfeng is also busy to enhance his own strength, did not pay attention to them.

In any case, the research vessel they sent was still in the last combat area to carry out investigations, and did not enter the scope of the base defense circle, and they only sent a "strong wind" to harass them in a specific way and drag them there completely.

Now that you have a real space warship in your hands, you don’t have to worry about any country on Earth that threatens itself.

In fact, with its own foothold in the space station, it will be a joke that M-country wants to launch a nuclear strike on its own base.

All intercontinental ballistic missiles have to fly out of the atmosphere, and in the space beyond the atmosphere, with space-based weapons and space warships themselves, will let it fall to Earth again?

As for medium-range missiles, let alone the signing of the INF Treaty between M and E that year, and even if it is rebuilt, will they still let them launch?

Without worries, you will be able to move into space better.

After all, Li Chunfeng could not judge whether the mother of the ice man received the previous call for help signal, and could only take precautions to accelerate his own strength growth in order to cope with the crisis that may come in the future.

Therefore, the development of space is not only imperative, but also stepping up, and more talents are needed to help themselves.

These are some ideas derived from the study of some scattered social data in the Iceman warship.
