Li Fu nodded with satisfaction when he saw the results of the experiment. The power of "point light" is almost comparable to that of primary energy weapons. This kind of light-speed weapon has a very advantageous advantage in fighting in the void of the universe.

If a war breaks out in the void of the universe, the spacecraft, space warship, etc. of both sides will be very fast, basically at a speed of dozens of kilometers per second. With such a fast speed, traditional weapons will have no effect at all, and even the fastest intercontinental missile on the earth will not be able to catch up.

What's more, in the vacuum environment of the universe, many weapons are simply ineffective, and the aircraft, guns, etc. used in wars on Earth will basically lose their function.

Only weapons like space-based weapons and energy weapons can be used in the universe. First of all, the attack speed of weapons is fast enough to attack at a speed of lightning, and it is truly as fast as lightning. Even if it is your spaceship, the space warship can fly faster, it will definitely not be compared with 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, it can continue to launch attacks. It is completely a weapon born for cosmic warfare.

"Its power is enough. I wonder how far its attack distance is? Is there anything that can affect its attack?"

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

"Because light is diffusive, the farther it propagates, the more it spreads. Even if the light and energy of the laser weapon are highly concentrated, it will still spread. According to the data we tested in theory, the farthest effective attack range of point light can reach about 100,000 kilometers. Of course, if we improve in energy compression technology in the future, further compress more energy and light to a point, and its range can also be continuously improved."

"As for the things that restrict it from attacking, such as heavy rain, fog, snow and other weather, laser weapons can basically be declared invalid because light cannot penetrate areas containing a lot of smoke and water."

"In addition, laser weapons are all very precise instruments and cannot be damaged. Once there is any damage, it will be directly scrapped."

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

"A range of 100,000 kilometers is enough, but it will be affected so much. It seems that it is impossible to fully control the ground by deploying this laser weapon in space. The enemy can attack on rainy days, or artificially create smoke to affect it."

Yu Liang nodded. As long as many things are known to their defects, there is nothing terrible about them. The power of laser weapons is very powerful, but they are affected by the weather.

"This laser weapon itself is more used in cosmic warfare. In the environment of cosmic vacuum, the power of the laser weapon can be fully exerted. If it deals with ground targets, there are still many things that affect it."

Li Fu also nodded slowly. If it were rainy days, laser weapons would not even be as good as fire sticks, and they would have no effect at all, but in space environments, they would be a real sword.

"With the weapon system, our Sky City plan can continue to start, and we need to speed up."

...

At the huge airport of Fuyun Group Space Center in Longling Town, a huge "Hercules" space plane was accompanied by roars, dragging its dazzling white tail flames into the air, and soon disappeared from everyone's sight. In just a few minutes, it had already broken through the earth's atmosphere and came to outer space to move around the earth.

In the space plane, Luo Xiaoyao, Zhan Fei and other astronauts trained by Fuyun Group themselves have already put on space suits that can be formed in space, and are ready to start a tense and dangerous work to build a sky city!

At the ground command center, Li Fu, Chen Bin, Yu Liang and others were all nervous at this time. This was the first time to build a large man-made object in outer space. Although many experiments have been conducted and the assistance of huge space planes, it is technically not difficult at all.

But after all, large-scale man-made objects were built in space, and this time it was laying the foundation for the Sky City, so everyone became nervous at this time.

"Didi! The Climate Eye navigation system tracks and locates, and the space plane is expected to enter the predetermined track in 10 minutes."

Fuyun Group's own global positioning system, Climate Eye System, is now fully activated in space, and dozens of satellites provide extremely accurate positioning services for the space planes.

"Altitude 510 km, speed 10.2 km per second, reaching the predetermined track, requesting instructions!"

The virtual machine worn by Luo Xiaoyao reported all the current status of the aerospace plane. After several changes of orbits, the aerospace plane has reached the predetermined track.

Generally, large artificial objects like the International Space Station and the Heavenly Palace in space will not be too high in height because they need to use the gravity of the earth to operate, so that they can orbit the earth without consuming energy.

For example, the height of the International Space Station is only between 390 kilometers and 405 kilometers, and the original orbit of the Tiangong was only between 330 and 350 kilometers. Later, after the aerospace plane appeared, Huaxia then changed the orbit of the Tiangong, increasing its height to 430-450 kilometers. The main reason is that the mass of the Tiangong is constantly increasing.

If the orbit is too close to the earth, it will continue to decline every year due to the influence of the earth's gravity, and will eventually be completely absorbed on the ground by the earth's gravity, causing devastating disasters. Therefore, the larger 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 drifting into space, so the higher the requirements for a powerful propulsion system.

Huaxia, who has mastered powerful plasma engines, naturally doesn’t have to be afraid of this. There are multiple powerful plasma engines installed on the Tiangong, which is enough to ensure the safety of the Tiangong, and the same is true for Li Fu.

The planning of Sky City is very large, the mass is also very large, and the orbital height is naturally higher. As for power propulsion, there is no worry, and plasma engines are also indispensable.

"start!"

After receiving the news, Chen Bin, who was responsible for the construction of the Sky City at the ground command center, did not hesitate. At this time, the orbit and speed of the spacecraft were located, etc. had completely met the requirements.

In space, the side of the huge Hercules space plane slowly opened, revealing its huge belly. The first one to stretch out were several flexible mechanical arms. Then Luo Xiaoyao, Zhan Fei and several other astronauts also floated out of the space plane in space suits. There was a long rope connected behind each person's space suit.

Originally, with the technological strength of Fuyun Group, it was possible to develop a spacewalk space suit that did not require rope connection. However, for safety reasons, this ancient method was adopted, and the astronauts felt more at ease.

Within the huge belly of the aerospace plane, large parts began to be brought out by mechanical forces. Because only microgravity is received in space, it does not require much force to push an object of huge mass to move.

The mechanical arms flexibly transported these parts that had been strictly calculated in the order that had been set long ago, while Luo Xiaoyao and others began to get busy.

Fuyun Group did not adopt the method of building the International Space Station and the Heavenly Palace. The construction methods of the National Space Station and the Heavenly Palace are actually very simple. They first launch a main cabin into space, then launch one by one, dock the main cabin, and slowly expand it in turn, and finally slowly form the current huge scale.

The advantage of this operation is that it is very simple to build. The space capsule can be launched into space with rockets, and it is easier to connect. One capsule and another capsule slowly dock.

The disadvantage is that astronauts can only live in one cabin, with very limited space and cannot conduct large-scale scientific experiments. The future development has also been affected, because there can only be one space capsule, and one space capsule is constantly added. No matter how many space capsules are added, its own space is quite limited, and there is no way to say that large factories, laboratories, etc. are built in space.

The construction of Sky City is completely different. The technical difficulty is very high at the beginning. It is necessary to build the main skeleton of Space City Space Port, slowly build the space port, and then slowly build living areas, factory areas, agricultural areas, scientific research areas, etc. based on the space port.

Its advantage is that the development and expansion of Sky City will not be limited in the future. It can have a very large space, which is enough to build large space factories, space agricultural areas, living areas, etc. At the same time, because of its advanced space port, the parking of aerospace planes is more convenient and fast.

Of course, its disadvantage is that it is difficult to build and has high technical requirements. The construction of the skeleton is very troublesome at the beginning. It cannot be as simple as the International Space Station to dock a space capsule or a space capsule.

However, this is not a problem for Li Fu. The scientists of Fuyun Group have the largest "Hercules" aerospace plane in the world. With Li Fu and the guidance of civilization seeds, 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 materials transported by one takeoff has exceeded the quality of the International Space Station. If traditional technology is used to build the Sky City, it will be no difficulty at all.
