Doubt it anymore.

The water drop crystal in Wei Ming's hand is definitely suitable as a cutting bit for high-end machine tools.

Because in the hand, it is close to a smartphone, and it may weigh more than 200 grams.

It's smaller than a drop of water.

Its density can be imagined.

As for the hardness, it doesn't need to be tested to guess how terrifying it is.

After all, this is a stable substance born in an environment of tens of millions of degrees of heat and hundreds of thousands of standard air pressures, and there is no more robust item on the Blue Star.

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

The bit problem is solved.

The teardrop-shaped surface is too rounded and not sharp enough to be conducive to cutting, but the solution is simple: first close the gravitational radius, and then use Xiao Hei's horizon to sharpen a 1-nanometer "knife edge", sharp enough to cut a thinness of exactly 1 nanometer.

It's just that according to this efficiency, Wei Ming can only make a drop crystal in a day.

The yield is simply too low and too draining.

Is there any way to fix this?

After consulting several physics experts, Wei Ming found a solution.

Use pools to slow down.

Water has a very strong ability to slow down, for example, a bullet with an initial velocity of more than 600 m/s will reduce its lethality by 90% after passing 1 meter in water, and the speed will be reduced to zero at a distance of 10 meters.

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

At the end of the pool, a row of steel plates with a thickness of up to 1 meter was prepared.

Physical mathematicians have done simulation calculations, due to the small size, the speed of the 0.3 mm diameter water drop crystal, even if it reaches 0.1 times the speed of light, after the deceleration of the 400-meter pool, its momentum is at most about 1/10,000, and the steel plate behind it can be completely blocked.

So the rest is pretty straightforward.

A large deceleration pool.

Place a row of steel plates.

Prepare 300 tons of crushed coal.

and a vacuum vessel with an immediate repairable surface.

Preparations took a week.

November 16th.

In this day, using Xiaohei, absorbing 300 tons of coal, Wei Ming produced a total of more than 300 drop crystals.

Like a pea shooter, it squirts one every two minutes for ten hours.

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

As a result, the staff searched for several days, digging dozens of meters of soil, and found only 33 droplet crystals in total.

More than 80 percent of the others are missing.

Wei Ming asked the staff to give up the search, counting the previous one, 34 water drop crystals are enough for the time being, if there is still a need in the future, prepare a deceleration pool of more than a kilometer, and place a five-meter-thick deceleration steel plate behind it, which will definitely be able to find most of the water drop crystals.

However, Wei Ming's side gave up the search, and a special department did not give up.

They issued a bounty revelation that as long as someone finds a "crystal tear" and hands it over to the government, they can get a high prize of 1 million yuan.

If you find a few, you will give a few 1 million, and there is no upper limit.

"Loser, such a precious thing, a substance with a hardness of more than 10,000 on the Mohs scale that is not found on the brand-new blue star, I won't look for dozens of them, and its value is not too much for five million a piece! A lot of them must be recovered! ”

This expert is about to go crazy, the Mohs hardness is more than 10,000, the hardest artificial polymeric diamond nanorod on the Blue Star, the Mohs hardness is also 13, this small drop crystal, the hardness is thousands of times that of the highest hardness material in the Blue Star.

Hurry up and issue a bounty to find all the scattered droplet crystals.

Soon.

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

But it didn't take long for a legend about "Angel's Tears" to gradually circulate in society, rumors that "Angel's Tears" are the hardest substance in the world and will never be damaged, as long as you find a "Angel's Tears" and give it to your beloved lover, then the love between the two will be like "Angel's Tears", indestructible, and never separated.

"Angel tears are just the best industrial processing cutter heads, not a symbol of love, please sell them to the state for a million."

The expert is a little crazy, eager to grab all the 'angel's tears' that have been reduced to jewelry use, but obviously this is not feasible, and there are very few successful repurchase increases, but it has strengthened the love belief of many young men and women, and no matter how much money is added, the expert wants to cry without tears.

……

After the bit problem is resolved.

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

Compress.

The best way to get a high-density substance is compression.

After Xiao Hei turns on the gravitational radius, within the gravitational radius, a strong attraction is generated, and even the molecular chemical bonds can be easily torn apart, and the matter can be quickly swallowed clean.

But Wei Ming didn't want Xiao Hei to devour it now, but used Xiao Hei's strong attraction to compress the substance.

How to do this.

Very simple.

Wrap the outside of Xiao Hei with a hard shell that is not easy to be torn by gravity.

The water drop crystal made a few days ago, as long as you drill a hole in the center, let Xiao Hei live in the core, and then turn the gravitational radius strength to the appropriate size, you can create a gravity of more than 100,000 G.

Let the water droplet crystal stand still, and the alloy steel passes through the top, and the front, back, and sides are processed.

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

This special steel is twice as dense as ordinary steel, has very small gaps between atoms, and is a stable material with a stable physical structure that is not prone to metal fatigue.

Wei Ming named it "Super Iron".

It took two days to process more than 1,000 tons of "super iron".

"So much superiron, enough to build two to three high-end machine tools, the inside of this material, the atoms have almost no gaps, not easy to thermal expansion and contraction, and are very little affected by temperature, and this material can be used in the skeleton, shell and mechanical structure of high-end machine tools and Tyrannosaurus EUV in the future."

"The most important! After the high-end machine tool uses this material, no matter how the motor vibrates, it will not change the silk, but the energy will be dispersed and transmitted to the outside, which will not affect the machining accuracy of the high-end machine tool. ”

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

But......

Due to the process of processing "super iron", Xiao Hei only provides super gravitational force, and does not swallow any substance.

After the end of processing.

Wei Ming made another shocking new discovery.

He didn't know if it was intuition or illusion, Xiao Hei's gravitational radius seemed to be weakened a little.

Although it was only a little bit, he really felt that Xiao Hei had weakened a little, as if he had experienced a consumption.
