There's a black hole inside me

Wei Ming immediately adopted this plan.

It's just that the ring pipe has extremely high requirements on materials, and ordinary materials will only be broken down instantly.

Even super-titanium alloys are difficult to withstand. After firing a few missiles, they will wear out severely and become scrapped quickly.

Even the tens of thousands of degrees of high temperature generated by friction can melt many materials.

Cao Jun slightly adjusted his plan, that is, in the linear incident section of the ρ pipeline, a 10-kilometer-long straight pipe, filled with water, and rushed out at a certain flow rate, just like a high-pressure water pipe, using the ten-kilometer flow of water to weaken the More than half of the kinetic energy of a water droplet crystal.

The Ring Wind Tunnel will take care of the rest.

So it took Wei Ming half a month to build the pipeline.

A seamless pipe with a length of 110 kilometers, a diameter of 80 centimeters, and a wall thickness of 50 centimeters. It is made of high-temperature-resistant supertungsten alloy material - such a pipe can be directly used as a gun barrel, firing at a rate of one round per second. A five-times-sonic artillery shell can be fired a hundred thousand times without being scrapped.

But it's still not quite enough.

Wei Ming also covered the main friction area of ​​the wind tunnel pipe with a thin layer of water drop crystal material - Wei Ming collected a circle and collected barely enough water droplets at the expense of scrapping the 'Water Drop 1' spacecraft. crystalline materials.

Because except for the water drop crystal itself, no material can withstand such severe friction.

Finally, the installation of pipelines and equipment took up to a week, and the location was still located at the Qiandao Reservoir.

Because of the need for heat dissipation, the ρ pipes must all be immersed in a cold water environment to obtain sufficient cooling. Otherwise, after a while, the temperature of the wind tunnel pipes will rise to more than 5,000 degrees, close to the temperature of the surface of the sun, even the rocks. It can be melted. How can it be done without a cooling environment?

…

March 10th.

Qiandao Reservoir.

The subsonic blower is in place and ready to go.

Wei Ming entered the underground space dug out of a hill on the shore.

There is a raw coal input conveyor belt in front of him.

In front is a pipe with a diameter of 30 centimeters (smaller) and a length of 300 meters. The air is continuously and rapidly extracted in a near-vacuum environment. Beyond it is a high-pressure water pipe that is ten kilometers long.

There is no need for a vacuum environment device now, because 99.9% of the air in the underground space where Wei Ming is located has been removed, forming a near-vacuum working environment.

Wei Ming had to put on a bulky sealed protective suit, dragging a tail-like gas pipe behind it, and enter the underground space to work.

There is no other reason than safety.

Without proper protection, water droplets traveling at tens of thousands of kilometers per second would hit the water flow directly, and the splash could kill Wei Ming.

The sonic boom produced by friction with the air can instantly deafen the ears.

Evacuating the working environment is also to reduce the destructive power of noise.

Of course, since absolute sealing cannot be achieved, a small amount of air molecules will still remain in the working environment. However, in a high-speed rotation environment, materials with different densities will be significantly stratified, but only carbon elements will be polymerized and compressed, and eventually synthesized into water droplet crystals.

Other elements may also be able to synthesize new crystals, but they have not yet been discovered.

The little black inside the body has been released in advance.

It begins to create a gravitational vortex, absorbs coal, and continues to accelerate.

Wei Ming was highly focused and operated carefully.

Pay attention to how far the latest water drop crystal can grow.

If it was too big beyond imagination, he would rather reduce the synthesis efficiency and shoot it in advance.

Soybeans are big.

Broad beans are big.

The glass beads are large.

Winter jujube is big.

Close to the size of a table tennis ball... Enough, enough, this size is completely big enough, why is it still tending to increase slightly.

emission!

Before it reached its 'mature' state, Wei Ming launched it like a hot potato.

Boom~!

There was a loud noise.

A slight but noticeable vibration can be felt underfoot.

Wei Ming did not rush to launch the second one, but after a while, he asked through the earphone: "How is it? Can the pipeline withstand it?"

"Can."

The other end of the headset said: "You can continue if it is within the tolerance range."

"Okay! I'm going to increase the transmission frequency."

Wei Ming nodded and immediately sped up the operation.

Boom boom boom!

One every ten seconds.

One every five seconds.

One every three seconds... The efficiency is at its maximum, because launching 'immature' water drop crystals in advance will delay about two seconds.

This frequency is already quite fast. Experts suggest that just keep this efficiency. If it is faster, the pipeline may not be able to withstand it.

In this state, synthesis continued for up to five hours.

The recycling team reported that they had successfully collected 5,978 steaming Type 5 water drop crystals that had just come out of the oven.

Diameter is 38mm.

The average mass of each piece is as high as 11687.4 grams.

Multiplied by the number of nearly six thousand.

The total weight exceeds seventy tons.

Wei Ming began to feel that this efficiency was too slow!

And there is always a feeling that I can’t have enough fun.

Because the water droplet crystal in the 'mature' state, after accelerating to the maximum state, only needs to reach a critical point, and then push it outward with a little force, it will be launched easily as if the water comes naturally, simple and efficient.

Unlike this, constantly 'pressing the brakes' and always paying attention to the size can cause internal injuries.

"Forget it, the frequency is maintained at three seconds, but the size is no longer controlled. Let's see how big it is in its mature state."

A few seconds later.

Mature type five water droplet crystals appeared.

An ellipsoid with a diameter of about 45 mm.

Slightly larger than a table tennis ball.

Slightly smaller than an egg.

Then with some anxiety, he shot the water drop crystal into the pipe.

boom!

Wei Ming heard a loud noise.

There was a violent vibration under my feet.

"Expert Liang, can the pipeline still bear the burden?" Wei Ming quickly asked the person in charge.

"I'm in a state of tinnitus here, and I can't hear for the time being!"

"I increased the volume of the water droplet crystal. Did the wind tunnel pipe collapse?"

Wei Ming asked louder.

"It can't be increased any more. It has clearly exceeded the upper limit of endurance. If it continues like this, the pipeline will collapse." The other party said with some horror.

"As long as it doesn't collapse, I don't care. The frequency of one every three seconds is no problem, but the volume must be kept to the maximum... I'm going to continue."

"Please do not!"

But Wei Ming ignored it. Since the first one was completely carried, he should be able to bear the rest.

boom!

boom!

boom! !

Until two hours later.

A loud bang of BOOM.

"Stop immediately! The ring pipe has collapsed and is completely damaged. Please stop launching immediately!" Expert Liang said in shock.

Wei Ming had no choice but to stop the synthesis and let Xiao Hei swallow a few of the growing ones.

"Mr. Wei, please come out and take a look. The entire Qiandao Reservoir lake water has been heated to 34 degrees, and many fish are almost cooked."

"How can this be?"

Wei Ming looked disbelieving and immediately left the work space, took off his protective clothing, and went to the lake to take a look.

The lake surface of Qiandao Reservoir, which covers thousands of square kilometers, is like a natural hot spring, filled with white mist that blocks the sky and the sun.

I put my hand in the lake water and felt it. It was indeed 34 or 5 degrees Celsius. Where the pipe was placed, I could see thick fog rolling in and the sound of gurgling water boiling could be heard.

"this……"

He was also stunned with surprise.
