After being a cosmic scavenger for more than half a month, Xiao Yu realized a truth: comets are all strong guys.

In terms of volume alone, a comet close to a star can be considered the largest star in the universe. The tail of the comet stretches out, and the maximum length can reach more than 100 million kilometers, like a huge broom, majestically sweeping through the universe. But when you get closer, you can realize how weak this guy is comet.

After traveling through the comet tail for more than half a month, Xiao Yu collected less than five kilograms of water, and the thinness of the material in the comet tail can be imagined. This collection efficiency made Xiao Yu extremely depressed. If Xiao Yu still had hair now, Xiao Yu would definitely be depressed and grab his hair one by one.

Xiao Yu is now 30,000 kilometers above or below the ecliptic plane. Anyway, it doesn't matter up and down in interstellar space, you can talk about it up and down.

The so-called ecliptic plane is an imaginary plane, which can be simply understood as the orbit of all the planets in the star system is mostly on a plane, and this plane is the ecliptic plane.

It's already quite close to the original Earth orbit. Through the optical telescope, Xiao Yu could already see countless small black meteorites above, exuding a palpitating light.

Xiao Yu has already made the orbit adjustment, and he plans to follow the earth's meteorite group around the sun for a period of time, after all, collecting materials is the right thing, although this speed is really slow.

The lens of the optical telescope slowly swept over, and an inconspicuous figure entered Xiao Yu's field of vision.

It is an irregularly shaped meteorite, about ten meters long, seven or eight meters wide, and five or six meters high. The diffuse reflection of light from the neighboring stars illuminated it, and then the light was collected by Xiao Yu again.

Xiao Yu's heart moved, and he immediately made some simple analysis of this meteorite. The results of the analysis immediately made Xiao Yu lift his spirits.

Analysis shows that the meteorite is composed of about 30% water, 69% iron, and trace amounts of nitrogen, silicon, hydrogen, oxygen, potassium and other elements. Among these trace elements, hydrogen and oxygen are the majority.

"It's ...... Is this a gift from heaven? Xiao Yu's heart immediately cheered up.

This meteorite has a volume of about four hundred cubic meters and a mass of more than three thousand tons! Even if hydrogen and oxygen each make up 0.1 percent of their mass, the total is six tons! With so much fuel, you can do so many things.

In particular, there are more than 900 tons of water on it! This water, when brought close to the sun, can also be ionized into hydrogen and oxygen with the help of the sun's ionization, which is another huge income. There are also more than 2,000 tons of iron, which is enough for Xiao Yu to repair the spaceship.

"Catch it! Be sure to catch it! Xiao Yu instantly made up his mind.

At this time, the star that stood in front of the meteorite moved away, and the sun's light shone directly on it.

Under the heat of the sun, the solid water, solid hydrogen and oxygen on the surface of this meteorite immediately began to volatilize rapidly, and fountains began to appear on the fluffy surface, countless gaseous substances spewed out, and the entire core was shrouded in a layer of vast white mist, dragging a long tail backwards.

Xiao Yu was anxious when he saw it: "These are all my treasures, they can't be volatilized in vain." ”

Xiao Yu immediately manipulated the spacecraft to block between the meteorite and the sun, and used his own solar panels to withstand the sun's heat. Without the sun's rays, the temperature of only a few kilometres in interstellar space immediately cooled it, and the long white tail dissipated at a speed visible to the naked eye.

Xiao Yu breathed a sigh of relief in his heart, and began to think about how to truly take this gift from God into his pocket.

When a large sweet cake is placed in front of you, there is plenty of motivation to make cutlery such as knives and forks. Xiao Yu no longer cares about energy consumption, controls the robot, searches the material storage room, and even dismantles some less important equipment, planning to use it.

The equipment manufacturing room is the most tightly protected place for Xiao Yu except for the main control room. Here, Xiao Yu collected a variety of the most basic and important machinery to ensure that he had sufficient manufacturing power after obtaining raw materials. Fortunately, the equipment manufacturing room was not too damaged during the previous collision.

As the robot worked without sleep or food, a mechanical claw with a high-strength cable of about 300 meters behind it was quickly manufactured.

Xiao Yu is now only about a few kilometers away from this meteorite. This distance, on an astronomical scale, is already close together, but compared to Xiao Yu's capture power, it is still a little longer. Xiao Yu had no choice but to carefully manipulate the small spaceship, adjust the power of the engine to the minimum, and slowly approach the meteorite block little by little, a few meters and a few meters.

It's actually risky. The distance of several kilometers is the shortest distance for Xiao Yu to manipulate the spaceship to dodge. After crossing this bottom line, if another meteorite collided with this meteorite at this time, causing it to collide towards Xiao Yu, Xiao Yu would not have time to dodge at all, and could only be destroyed by it.

"Wealth is in danger, damn, I did this ticket, and I will eat and drink spicy food in the future!" Xiao Yu was ruthless in his heart, but his actions were more cautious.

Gradually, the distance has been reduced to two thousand meters...... 1,000 ...... 500 meters......

Just when victory was in sight, suddenly, a dark and inconspicuous figure broke into Xiao Yu's sight. Xiao Yu was shocked, and saw that the figure hit the target meteorite at a relative speed of several hundred meters per second, and the target meteorite exploded into a burst of fire, and then rolled up, because of the heat of the impact, the solid water, carbon dioxide, hydrogen and oxygen on it began to volatilize violently, turning into a large cloud of mist.

Not only that, but the target meteorite was changed by this impact, and began to fly away in other directions, disappearing in a blink of an eye.

Xiao Yu was angry and anxious, and cursed the troubled meteorite a thousand times, and when the curse was over, he began to cheer up again, turning the astronomical telescope, looking around for the traces of the target meteorite.

Xiao Yu knew that because of the recoil force of the volatile gas and the original inertia, it would not be able to run far. Sure enough, after Xiao Yu searched for two hours, he finally found it in the direction of the ecliptic, about 600 kilometers away from him.

Xiao Yu's speed didn't dare to increase too fast, he only dared to maintain the relative speed of himself and this meteorite at a speed of fifty meters per second, that is, one hundred and eighty miles, and slowly approached it.

The speed of one hundred and eighty miles can be regarded as a lightning speed on the earth, and here, it is a compliment to say that it is a snail crawling. Xiao Yu ran for more than three hours before he regained access to the distance within three thousand meters.

"Damn, no matter how blind a guy dares to spoil Lao Tzu's good deeds, Lao Tzu will use a laser gun to kill you if he is desperate to consume energy." Secretly made up his mind, Xiao Yu cautiously began to approach.

The distance is getting closer and closer, and Xiao Yu's mind is getting closer and closer. Finally, the distance was reduced to 280 meters!

This distance is already within the range of the flying claw captured by Xiao Yu.

Xiao Yu aimed the muzzle of the gun at the target meteorite and decisively gave the order to launch.

The recoil force of the firing claw caused Xiao Yu's spacecraft to shake, which affected the accuracy of the claw, and the claw flew out like a sharp arrow, but did not hit the target meteorite, but passed by about fifty meters away from the target meteorite.

Xiao Yu was not discouraged, and controlled the machine to retract the flying claw, re-modify the recoil force parameters, and launch again.

Keep failing. The Flying Claw flew twenty meters next to the meteorite.

Continue to modify the recoil force parameters and continue firing.

Finally, this time Xiao Yu succeeded! The claw accurately hit the middle of the target meteorite, and the sharp claw pierced the fluffy outer layer of the target meteorite, and then opened and jammed inside the meteorite, firmly connecting it to Xiao Yu's spaceship.

The meteorite is struck by an external force and immediately flies in the opposite direction. The high-strength cable was stretched straight, and under the pull of the meteorite, Xiao Yu's spaceship flew out with it.

It's so wonderful in a weightless environment, and there are many things that go against common sense. If you are on Earth and you shoot a claw at a rock, the claw will never escape even if it catches the rock. This is because of the gravitational pull of the earth.

But this is in space, and there is no gravitational attraction on Earth. When a meteorite is stressed, it will inevitably react. When it is hit by the claws, it will flee in the opposite direction. This situation is like Xiao Yu tying himself to the tail of an arrow with a rope, and then shooting the arrow out with a bow, and then he was also carried up by the arrow.

This situation has long been considered by Xiao Yu, so Xiao Yu is not panicked at all. Xiao Yu didn't dare to force it to stop, because that kind of force would exceed the bearing capacity of the cable, and the cable would break. Xiao Yu only kept exerting force little by little, slowly reducing the kinetic energy of the target meteorite.

It took three hours and almost a thousand kilometers to fly before Xiao Yu finally subdued the meteorite. Then, Xiao Yu dragged the meteorite and slowly flew away from the ecliptic plane.

Just like a lion who quietly caught a calf in the herd, but did not dare to devour it surrounded by the cows, but moved the calf to a place far away from the herd before starting to eat, Xiao Yu did not dare to start his own meal here. Because it's too dangerous here.

It took three days for Xiao Yu to drag the target meteorite to a distance of 40,000 kilometers from the ecliptic. There was no trace of any other meteorite in sight. Looking at the delicious meal in front of him, Xiao Yu roared excitedly: "Open the meal!" ”
