Passing through the spatial film of the portal, Chen Yu stepped on the irregular surface of the asteroid, and the gravity disappeared in vain.

"This is the Bell asteroid. In general, the shape is oval, and the surface is mostly composed of a mixture of iron and nickel, and there seems to be calcium oxide, so it looks a little whitish in color. ”

"The diameter of the asteroid, you should have heard it just now, six kilometers, is not small. As for the quality and speed, there is nothing to say, let's work first, and strive to finish it as soon as possible. ”

Whether Bell's interception plan can succeed is not certain, Chen Yu restrained himself and did not say much.

Powered by the plasma engine to assist his standing, he lifted the fluttering oil barrel and stuck it in the empty tube at the end of the brush, then pressed the button.

"Buzz ......"

The vibrations of several motors were swirling, and the large brushes began to spray pure black paint, sticking to the planet's surface. Drops of ink that were bounced off by the impact force were not bound by gravity, and they were condensed into round spheres and floated in all directions.

Yes, the so-called "brush" is actually a dense network of soft pipes. As long as the paint is sufficient, the paint will be pumped by the special oil pump inside the brush, and the pressure and spray will be completed, which will greatly improve the efficiency of "brushing paint".

"Great device, huh?"

Looking at the camera, Chen Yu shrugged his shoulders, and under the impetus of the engine, he began the great cause of "saving the world": "The gravitational force provided by the asteroid is negligible, and if you want to smear it densely, you still have to stick to the surface of the planet and brush it slowly." ”

In the lecture room, buckets of paint passed through the portal and were thrown in by the staff of the Purple Mountain Observatory.

The big brush has a lot of horsepower, but it empties a 20-liter oil drum in just half a minute.

Pulling out the empty barrel, Chen Yu waved his right hand and smashed it directly, then grabbed the new oil barrel floating in the air and inserted it neatly into the tailpipe.

"Destroying empty barrels speeds up work. Otherwise, it won't be long before the oil drums are floating all over the sky, and you can't tell which one has oil and which one doesn't......"

【Professional!】

[Maybe the UP master's job is to paint the wall.] (funny)]

[Shocked! An anchor paints online and earns millions a day!]

[Wouldn't it cause space junk if it was littered like this?]

[When is it?Do you care about garbage?]

[You don't understand, this is the anchor adding drama to himself. It's a rare opportunity to save the world, even if it's just painting, you have to be domineering!]

【23333。 】

[I'm more concerned about the next official live broadcast of the up master, it seems that the authority has been improved......, right?

[Hope is a cosmic colony ship......]

On the surface of a lone asteroid, you can feel the emptiness and depth of the universe more and more.

The spin rock mass with a diameter of six kilometers is like a flat boat in the deep sea, with no end in sight. At this distance, the Earth, the Moon, Mars, Jupiter...... As small as mosquitoes and flies, you can't see them all.

Except for the blazing fireball in the distance, the whole world is only the starlight of the Milky Way

Learning improves grades, and work increases skills.

As Chen Yu brushed more and more, experience points accumulated, he brushed faster and faster, and he also discovered a trick. That is to clamp the brush to the crotch with both legs, riding the brush like Harry Potter riding a magic broomstick.

With an oil drum in the left hand and an oil drum in the right hand, the muscles of both legs control the direction of the brush and the engine pushes the ......

"Aha??? ！”

Waving the oil drum with both hands, Chen Yu jumped and flew around, like Li Yuanba, a double hammer on the battlefield, turning the boring painting operation into a human bewilderment.

[Hahaha......]

[Anchor, you're really a talent. 】

[I'm really looking forward to what future historians will say about this "magnificent" journey of salvation.] 】

[If they are seen by aliens, they may sigh at the abundance of species in the universe......]

[I'd like to call this a unique job!]

[I want to play too.] 】

[Child, this is saving the world, not playing.] 】

[Full of disobedience, I don't know where to start spitting ......]

【xswl……】

Forty-seven minutes later.

Chen Yu finally finished brushing the last deep concave crack, and shook the brush and oil drum hard: "Made, it's finally finished!"

Stretching, he controlled the plasma engine through the portal, flew back to the Observatory Square of Purple Mountain, took off his hand armor and looked at the barrage and time, put it on again, and said, "What should I do next?"

"This solar reflector is erected on the asteroid's axis of rotation. The person in charge beckoned the staff and came to Chen Yu with a piece of equipment nearly thirty meters away: "It's a little heavy, do you need astronaut help?"

"No, just find a few people to help me carry the other end. Chen Yu waved his hand, lifted the lighter tail of the device, and asked as he stepped back, "How to install this thing?"

"You need to weld, and the whole set of space welding tools is in the equipment. You arrive at the asteroid with the solar panel, and the observatory headquarters will send a deployment command, and you can just weld a few brackets to the surface of the asteroid. ”

"I'm not good at welding. Chen Yu frowned.

"It's very simple, find a hard enough surface of the iron structure and weld it tightly. There are high-power suction cups at the bottom of the support columns of the solar panel, which is the fixed body. ”

"Oh, that's understood. ”

Chen Yu nodded and exited the portal with the device.

He understood, just a few welds......

Entering space, the weight of the sun's reflector suddenly disappears. Waving his hand to the staff inside the portal, signaling them to leave, Chen Yu pulled hard, and all the equipment was dragged into space.

Without interacting with the audience, he flew to the asteroid axis with a thirty-meter-long device, landed, and planted it upright and stuck it in the ground.

"It's ready to be expanded. ”

After a full minute, the sun reflector began to unfold slowly like an umbrella.

This is the greatness of the universe.

A simple command, even at such a "close" distance, the light has to go for tens of seconds.

Without sophisticated quantum communication technology, spaceflight would be a catastrophic journey.

"Buzz ......"

The vibration of the large propeller shaft passed through the asteroid rock mass and reached Chen Yu's feet.

The umbrella-like structure extends the height while spreading the umbrella pages. In a short time, a huge solar reflector with a diameter of 50 meters and a height of 200 meters was erected.

Stretching out his hand and shaking the support rod, Chen Yu found that the suction cup at the bottom was unexpectedly explained, so he didn't delay any longer, opened the big toolbox, took out the welding equipment and began to weld the thick wire rope floating in space.

"Polishing the atomic bomb, tiling the Great Wall, welding the space station...... I don't have to be the third kind of technical content, right?"

[Among the many heroes who save the world, you are the most heroic. 】

[Tears.] 】

[Don't say it, leave the group.] 】

[Huh, what is the anchor doing? Is the crew filming? Big production!]

[it!There's a new one here!Come and bully her!]

[The pot has been set. 】

【Water is boiling.】 】

【Seasoning preparation ......】

"Zizi!"

"Zizi Zi ......"

After welding the first steel bar, Chen Yu tentatively pulled it hard, but he didn't move: "It looks relatively strong." Some people, no matter what they do, look like ......"
