Li Fu nodded with satisfaction when he saw the results of the experiment, the power of the "point light" was almost comparable to that of the primary energy weapon, and this light-speed weapon was very advantageous when fighting in the cosmic void.

If there is a war in the cosmic void, the speed of the spaceships, space warships, etc. on both sides is very fast, basically casually tens of kilometers per second, such a fast speed, traditional weapons have no effect at all, even the fastest intercontinental missiles on the earth can not catch up.

What's more, in the environment of the cosmic vacuum, many weapons cannot be used at all, and the planes, guns, etc. used in the war on the earth are basically useless.

Only weapons like space-based weapons and energy weapons can be used in the universe, first of all, the attack speed of the weapon is fast enough, and the attack speed of light is really as fast as lightning, even if your spaceship and space battleship fly fast, it will definitely not be comparable to the speed of light.

Secondly, the power of energy weapons is theoretically unlimited, and there is also the attack method of energy weapons, as long as there is energy, you can continue to attack, and it is completely a weapon born for space warfare.

"It's powerful enough, I wonder how far it can attack? Are there any attacks that can affect it? ”

After listening to Bai Cai's words, Chen Bin asked thoughtfully.

"Because light is diffusive, the farther it travels, the more it spreads, even if the light and energy of the laser weapon are highly concentrated, but it will still diffuse, according to our theoretical test data, the farthest effective attack range of the point light can reach about 100,000 kilometers, of course, if we improve the energy compression technology in the future, further compress more energy and light to a point, its range can also be continuously improved."

"As for the things that limit its attacks, such as heavy rain, fog, heavy snow, etc., laser weapons can basically be declared invalid, because light simply cannot penetrate areas containing a lot of smoke and water vapor."

"In addition, the instruments of laser weapons are very sophisticated instruments, which cannot be damaged in any way, and once there is any damage, it will be scrapped directly."

Bai Cai nodded and told the flaws of the laser weapon.

"With a range of 100,000 kilometers, this attack distance is enough, but it will be affected so much, it seems that it is impossible to completely control the ground by arranging this laser weapon in space, and the enemy can attack on a rainy day, or artificially create smoke to affect it."

Yu Liang nodded, as long as you know its flaws, there is nothing to be afraid of, the power of laser weapons is very powerful, but it is affected by the weather.

"The laser weapon itself is more used in space warfare, in the environment of the cosmic vacuum, the power of the laser weapon can be fully deployed, and there are still many things that affect it when dealing with ground targets."

Li Fu also nodded slowly, if it was on a rainy day, the laser weapon was not as good as a burning stick, and it would have no effect at all, but in the environment of space, it was a real sword.

"With the weapon system in hand, our Sky City project can continue to begin, and we have to speed up the pace."

……

At the Fuyun Group Space Center in Longling Town, on the huge airfield, a huge "Hercules" aerospace plane accompanied by bursts of roar, dragging a blazing white and dazzling tail flame into the air, and soon disappeared from everyone's field of vision, and in just a few minutes, it had already broken through the earth's atmosphere and came to outer space to begin to orbit the earth.

In the aerospace plane, Luo Xiaoyao, Zhanfei and other astronauts cultivated by Fuyun Group have already put on spacesuits that can be formed in space at this time, ready to start the tense and dangerous work to build a city in the sky!

Here in the ground command center, Li Fu, Chen Bin, Yu Liang and others are also nervous at this time, after all, this is the first time to build a large man-made object in outer space, although many experiments have been carried out between them, coupled with the assistance of a huge aerospace aircraft, technically speaking, there is no difficulty at all.

But after all, it was a large-scale man-made object in space, and this time it was to lay the foundation for the castle in the sky, so everyone was nervous one by one at this time.

"Didi! The clairvoyant navigation system tracks and locates, and the aerospace aircraft is expected to enter the predetermined orbit in 10 minutes. ”

Fuyun Group's own global positioning system, the clairvoyance system, is in full swing in space at this time, and dozens of satellites provide extremely accurate positioning services for aerospace aircraft.

"Altitude 510 km, speed 10.2 km/s, reach the predetermined orbit, ask for instructions!"

The virtual machine worn by Luo Xiaoyao reported all the current status of the aerospace aircraft, and after several orbit changes, the aerospace aircraft had reached the predetermined orbit.

Generally, large man-made objects such as the International Space Station and Tiangong in space are not too high, because they need to use the gravitational pull of the earth to orbit, so that they can orbit around the earth with almost no energy consumption.

For example, the altitude of the International Space Station is only between 390 kilometers and 405 kilometers, and the original orbit of Tiangong is only between 330 and 350 kilometers.

If the orbit is too close to the earth, it will be affected by the earth's gravity every year, and will eventually be completely absorbed by the earth's gravity to the ground, causing a devastating disaster, so the greater the mass, the higher the orbit will be.

Of course, the higher the orbit, the weaker the binding force of the Earth's gravity, and the greater the risk of escaping the Earth's gravity and drifting into space, so the higher the requirements for a powerful propulsion system.

Huaxia, who has a powerful plasma engine, naturally does not need to be afraid of this, there are many powerful plasma engines installed on Tiangong, which is enough to ensure the safety of Tiangong, and the same is true for Li Fu.

The planning of Sky City is very large, the quality is also very large, the orbit height is naturally higher, and there is no worry about power propulsion, and plasma engines are also indispensable.

"Let's go!"

After receiving the news, here in the ground command center, Chen Bin, who was in charge of the construction of Sky City, did not hesitate, and at this time, the orbit and speed of the aerospace aircraft had fully met the requirements.

In space, the side of the huge "Hercules" aerospace plane slowly opened, revealing its huge belly, and the first thing that stretched out was a few flexible mechanical arms, and then Luo Xiaoyao, Zhanfei and other astronauts also wore spacewalking spacesuits and floated out of the aerospace plane, and there was a long rope behind each person's spacesuit.

Originally, with the scientific and technological strength of Fuyun Group, it was possible to develop a spacewalking spacesuit that did not require a rope connection, but for the sake of safety, this ancient method was still adopted, and the astronauts were more at ease.

Inside the huge belly of the aerospace plane, driven by the machine, large parts began to be brought out by the force of the machine, because space is only subject to microgravity, so it does not need a lot of force to push a huge object to move.

One by one, the robotic arms flexibly carried out these parts that had been rigorously calculated in the order that had been set long ago, and Luo Xiaoyao and others began to get busy.

Fuyun Group did not adopt the method of building the International Space Station and Tiangong, the construction method of the National Space Station and Tiangong is actually very simple, first launch a main module into space, and then launch a space capsule to connect to the main module, and slowly expand in turn, and finally slowly form the current huge scale.

The advantage of this operation is that it is very simple to build, the capsule can be launched into space with a rocket, and it is easier to dock, one cabin after another.

The disadvantage is that astronauts can only live in one capsule, the space is very limited, there is no way to carry out large-scale scientific experiments, and the future development has also been affected, because only one capsule, one capsule is constantly added, no matter how many capsules are added, its own space is also quite limited, and there is no way to build large-scale factories, laboratories and so on in space.

The construction of the city in the sky is completely different, the technical difficulty is very high at the beginning, it is necessary to build the main skeleton of the space port of the space city first, slowly build the space port first, and then slowly build the living area, factory area, agricultural area, scientific research area and so on based on the space port.

Its advantage is that the development and expansion of Sky City will not be limited in the future, and it can have a very large space, enough to build a large space factory, space agricultural area, living area, etc., and because of the advanced space port, the parking of aerospace aircraft is more convenient and fast.

Of course, its disadvantage is that it is difficult to build, the technical requirements are high, and the construction of the skeleton is very troublesome at the beginning, and it cannot be docked as simply as a space capsule and a space capsule like the International Space Station.

However, this is difficult for Li Fu, it is difficult for the scientists of Fuyun Group, with the world's largest "Hercules" aerospace aircraft, coupled with the guidance of Li Fu and the seeds of civilization, it is definitely not a problem to build a space city.

The huge aerospace plane can transport thousands of tons of materials at a time, and the quality of the materials transported by a single take-off has already exceeded the quality of the International Space Station.
