Li Fu did not return to the ground for the time being, because Li Fu already knew from his secretary Ding Xuan that there were dozens of waves of people in the company who wanted to see Li Fu, and each of these people was a representative of a world power, or a representative of the world's top consortiums, and even a person with a background in China, who was very difficult to deal with.

Li Fuzhong also knows very well why they came, Fuyun Group has the only spaceship in its hands that can go to the asteroid belt to mine asteroids, and asteroids are now synonymous with gold and silver mountains, and if you pull an asteroid to the earth, it will also be a huge return of tens of billions or hundreds of billions.

Therefore, Li Fu simply chose to stay in space first, let Fang Zheng, who is good at dealing with these things, deal with it, and simply stay in space to smelt the asteroid that was pulled back.

In the void not far from the Sky City, there is a huge solar space farm, which is also the largest solar space farm in space, with an area of more than 15 million square meters, and the annual power generation is equivalent to almost 2 Three Gorges.

After years of development, the number of employees of Fuyun Group has reached millions, and all kinds of factories, laboratories, etc. are all electricity-swallowing monsters, and the electricity bills paid every day are hundreds of millions.

At this time, the asteroid brought back from the asteroid belt was dragged into the void by the spacecraft, maintaining the same speed as the solar farm, forming a relatively stationary state.

"Units report on the situation."

Yu Liang, who was in charge of directing the asteroid smelting this time, gave the order in a loud voice.

"The farm is ready."

"The metal separation group is ready."

"Security Group Ready,"

“……”

The teams kept reporting on the situation, and everything was ready.

"Start smelting asteroids."

Yu Liang heard the reports of the teams, nodded with satisfaction, and gave the order to smelt the asteroid.

As his order was given, every solar panel in the solar farm began to rotate slowly, and the supercomputer calculated everything, and the angle and direction of each reflector mirror were controlled by the supercomputer, exactly the same!

Rays of sunlight began to gather on the asteroid placed in space, and there was no reaction at first, but as more and more sunlight gathered, the space where the asteroid was located began to become bright and dazzling.

The normal temperature in space is more than minus 100 degrees, and now more and more sunlight is gathering, and the temperature of the asteroid in the void begins to increase sharply, and soon rises from more than minus 100 degrees to hundreds of degrees.

At this time, some of the gas and water on the asteroid began to evaporate and escape, and were collected by the collector that had been prepared for a long time.

As more sunlight is concentrated on the asteroid, the temperature soon rises to more than 1,000 degrees, and at this time the metal on the asteroid has begun to liquefy, and the asteroid is almost all composed of iron, and the melting point of iron is more than 1,000 degrees.

Because all the sunlight is controlled by supercomputing, and the amount of sunlight that is gathered by the computer is determined according to the temperature on the asteroid.

This iron-containing asteroid is always controlled by the sunlight that keeps its temperature controlled by about 2,000 degrees, which can melt the entire asteroid the fastest time, and at the same time will not reach the boiling point of iron due to the high temperature, allowing the molten iron to evaporate.

The outside of the asteroid has melted into molten iron, but the inside is still solid, and it needs to be continuously heated and heated up to make the iron inside melt into molten iron, and the temperature of about 2000 degrees is just right, but it takes a little time.

At the same time, two strange machines use long magnetic pliers to continuously use magnetism to attract the molten iron that has melted out, and shape it at the same time according to the desired shape.

You must know that there is no gravity in space or only affected by microgravity, all the liquid appears in a spherical structure, the huge and red molten iron ball is shaped by strong magnetic attraction and shaped, shaped into a variety of parts, and at the same time uses the ultra-low temperature of more than minus 100 degrees in space for cooling, these parts quickly turn from red to black.

The strength and hardness of the metal smelted in this way are very high, and because it is smelted in space, it is like kneading noodles, you can rub whatever shape you want, and smelt it as much as you want, which is better than the assembled parts.

In less than an hour, the asteroid containing more than 9 million tons of iron was smelted into various parts, and the mechanical arm on the Dumbo spaceship was dragged back to Sky City to be used.

These parts need to be further processed before they can be used, for example, the internal stresses of the metal can also be eliminated by placing them in space.

The method and speed of smelting metal in the interstellar era far surpassed that of the terrestrial era, and nearly 10 million tons of steel were smelted in 1 hour, and they were also processed into parts at the same time, and the power of science and technology is so great!

"It seems that the number of asteroids we have mined is still too small, it's only been 1 hour, and an asteroid has been smelted cleanly, and it doesn't feel like it's enjoyable enough."

Yu Liang saw the empty void, the whole person pursed his lips slightly, the efficiency of using space solar energy to smelt metals is too high, nearly 10 million tons of metal are not only easily smelted, but also processed into the parts he wants, this speed is definitely not comparable to the smelting furnace on the ground.

"In the future, there will be asteroids for you to smelt, and the key now is to build more spaceships."

Li Fu on the side smiled slightly, almost all of the steel smelted this time was used to make new spaceships, and Li Fu was now in urgent need of a large number of spaceships to mine asteroids in the asteroid belt.

"Hehe, this time with nearly 5 million tons of steel, we can build a larger spaceship, and when the time comes, bringing back hundreds of millions of tons of asteroids at a time will be enough for us to use for a while."

As soon as he heard about the construction of a new spaceship, Yu Liang's eyes lit up, the Dumbo spaceship was just a spaceship larger than the aerospace plane, and it could only drag an asteroid of 10 million tons at most, which was already its limit.

In the planning, Fuyun Group actually wants to build a larger spaceship, the "Giant Spirit God" spaceship, the "Giant Spirit God" spaceship will be ten times the current Dumbo spaceship, the engine alone is enough to be comparable to an aerospace aircraft, and its thrust will be enough to pull a massive asteroid with a mass of hundreds of millions of tons.

It's just that to build such a huge spaceship, the steel resources consumed will be very large, and because of its large mass and strong thrust, the core keel must be a whole piece of forging at one time, if it is split into multiple parts and then assembled, it will not be able to withstand its huge thrust.

With such a huge part, there is naturally no problem in processing it on the ground, but there are no tools that can be transported into space at all, and the aerospace plane is only a few tens of meters in length.

Therefore, if you want to make such a huge number of parts, and then make the "Giant Spirit God" space plane, you must smelt metal in space, forge parts, and complete the core keel and parts directly in space.

This is also why Li Fu built a space solar farm first, because this is used to smelt asteroids, mine asteroids, smelt them directly in space, and forge super-large parts at one time, in preparation for the next step to build a larger spaceship.

In the future, if you want to build space warships and so on, it is inevitable to do it step by step, and it is absolutely impossible to say that you want to build large spaceships and space warships just on the ground.

"I'm depressed when I say this, originally this time we just could build 20 'Giant Spirit God' spaceships, but we just let the country share half of it, I guess they will definitely waste these steel resources, their eyes are now staring at the moon, blooming everywhere on the moon, grabbing resources, and needing a lot of steel."

Chen Bin on the side also shook his head helplessly, the steel that has just been smelted, the country requires that it be made into a whole and a whole steel plate according to the standard specifications, and at a glance you know that it is used on the moon, not for building spaceships.

"What's so depressing about this, now all countries in the world are fighting fiercely on the moon, and the far side of the moon has almost been carved up, I heard that the foot basin chicken and the south stick are fighting each other for a piece of territory on the far side of the moon, and they are really almost staged a moon version of the world war."

"Our country now occupies more resources on the moon is also a good thing for our China, 8% of the resources of the moon are occupied by us, and we don't have to worry about resources for a long time in the future, after all, the moon is the closest planet to our earth, and the various resources on the moon are very rich."

"Even if we mine 10 million asteroids in the asteroid belt, we can't be the moon, and we have to travel hundreds of millions of kilometers for thousands of miles, and they can see much more clearly than us."

Li Fu on the side smiled and shook his head, Fuyun Group also occupies a huge territory on the moon, and it is very clear how rich the resources on the moon are.
