There's a black hole inside me

No more doubts.

The water drop crystal in Wei Ming's hand is definitely suitable for use as a cutting head (and grinding tool head) for high-end machine tools.

Because when you hold it in your hand, its weight is close to that of a smartphone, probably a little over 200 grams.

The volume is smaller than a water droplet.

Its density can be imagined.

As for the hardness, you can guess how terrifying it is without testing.

After all, this is a stable substance that was born in an environment of tens of millions of degrees of high temperature and millions of standard air pressures. There is no way that anything stronger than this can exist on the Blue Star.

When diamond encounters it, it will be crushed like tofu.

The cutter head problem is solved.

The drop-shaped surface is too rounded and not sharp enough, which is not conducive to cutting, but the solution is also very simple: first close the gravitational radius, and then use Xiao Hei's vision to cut out a 1-nanometer "edge" that is so sharp that the cutting thickness is exactly 1nm.

Just based on this efficiency, Wei Ming can produce a water drop crystal in one day.

The output is simply too low and too mentally draining.

Is there any way to solve this problem?

After consulting several physics experts, Weiming found a solution.

Use the pool to slow down.

The deceleration ability of water is very strong. For example, if a bullet with a muzzle velocity of more than 600 meters/second passes through 1 meter in the water, its lethality will be reduced by 90%, and its speed will drop to zero ten meters away.

Wei Ming had people prepare a pool with a length of 400 meters.

At the end of the pool, a row of steel plates with a thickness of 1 meter is set up.

Physical mathematicians have done simulation calculations. Due to the small size, the speed of a water droplet crystal with a diameter of 3 mm, even if it reaches 0.1 times the speed of light, will decelerate after passing through a 400-meter pool. Its momentum will be left at most about one ten thousandth. What follows? The steel plate can completely block it.

So the next step is very simple.

A large deceleration pool.

Place a row of steel plates.

Prepare 300 tons of pulverized coal.

and a vacuum vessel whose surface can be repaired immediately.

Preparations took a week.

November 16th.

In this day, using Xiao Hei to absorb 300 tons of coal, Wei Ming produced a total of more than 300 water drop crystals.

Like a peashooter, one shot out every two minutes for ten hours.

In fact, the escape speed of water droplet crystals is not as exaggerated as 0.1 times the speed of light, up to 10,000 kilometers per second. However, due to the excessive density and weight of more than 200 grams, the deceleration effect of the pool is not ideal, and a 1-meter-thick steel plate cannot withstand it. live!

As a result, the staff searched for several days and dug tens of meters of soil, but only found a total of 33 water drop crystals.

More than 80 percent were missing.

Wei Ming asked the staff to give up the search. Counting the first one, 34 water drop crystals were enough for the time being. If needed in the future, a deceleration pool with a length of more than a kilometer would be prepared, with a five-meter-thick deceleration steel plate placed behind it. , this will surely bring back most of the water drop crystals.

However, Wei Ming gave up the search, but a certain special department did not give up.

They announced a reward. As long as someone finds a "Crystal Tear" and turns it over to the government, they can get a high bonus of 1 million yuan.

If you find a few coins, you will be given 1 million. There is no upper limit.

"Prodigal son, such a precious thing, a brand-new substance with a Mohs hardness of over 10,000 that is not found on Blue Star, I have only found dozens of it and stopped looking for it. Its value is not exaggerated at five million per piece. ! We must find a lot of them!”

This expert is going crazy. The Mohs hardness exceeds 10,000. The Mohs hardness of the artificial polymeric diamond nanorods, which is the hardest on Blue Star, is only 13. This small water droplet crystal has the hardness of the hardest material on Blue Star. Thousands of times.

Hurry up and issue a reward to find all the missing water drop crystals.

soon.

A lucky person accidentally picked up the "Crystal Tears" and happily received a million-dollar reward.

But not long after, a legend about "Angel Tears" began to circulate in the society. It was rumored that "Angel Tears" were the hardest substance in the world and would never be damaged. As long as you found an "Angel Tears", you would be given a gift. Give it to your beloved, and the love between the two will be like "angel's tears", indestructible and never separated.

"Angel's Tears are just the best industrial processing blades, not a symbol of love. Please sell them to the country for one million."

Experts are a little crazy and want to grab all the 'Angel Tears' that have been reduced to jewelry. But obviously this is not feasible, and there are very few successful repurchases at increased prices. On the contrary, it has strengthened the love of many young men and women. Faith will not be sold no matter how much the price is increased. Experts are crying over this.

…

After the cutter head problem is solved.

How to obtain a high-density substance also troubled Wei Ming for several days.

compression.

To obtain high-density substances, the best way is to compress them.

After Xiao Hei turns on the gravitational radius, the strong attraction generated within the gravitational radius can even easily tear apart the chemical bonds of molecules and quickly swallow up matter.

But now Wei Ming doesn't want Xiao Hei to swallow him up, but only uses Xiao Hei's strong attraction to compress the material.

How should this operation be performed?

Very simple.

Wrap Xiaohei with a hard shell that is not easily torn apart by gravity.

For the water drop crystal created a few days ago, we only need to drill a hole in the center, let Xiao Hei live in the core, and then increase the intensity of the gravitational radius to a suitable size to create a gravity of about 100,000 G.

Let the water drop crystal stand still, and the alloy steel passes from above, and the front, back, and sides are processed.

Finally, a special steel with a density of 15.83g/cm3 was obtained.

The density of this special steel is twice that of ordinary steel. The gaps between atoms are extremely small, the physical structure is stable, and it is not prone to metal fatigue.

Wei Ming named it "Super Iron".

It took two days to process more than a thousand tons of "super iron".

"Such a large amount of super iron is enough to build two or three high-end machine tools. There are almost no gaps in the atoms inside this material. It is not prone to thermal expansion and contraction, and is minimally affected by temperature. In the future, high-end machine tools, Tyrannosaurus EUV Skeletons, shells, and mechanical structures can all be made of this material.”

"The most important thing! After high-end machine tools use this material, no matter how the motor vibrates, it will not change. It only disperses the energy and conducts it to the outside, without affecting the processing accuracy of high-end machine tools."

"Coupled with the extremely hard water drop crystal cutter head, the high-end machine tool Phoenix is ​​about to be born!"

but……

Because during the processing of "super iron", Xiao Hei only provided super strong gravity and did not swallow any matter.

After processing is completed.

Wei Ming made another extremely shocking new discovery.

He didn't know whether it was intuition or an illusion, but Xiao Hei's gravitational radius seemed to be weakened just a little bit.

Although it was only a little bit, he did feel that Xiao Hei had become a little weaker, as if he had experienced a consumption.
