Chapter 257: The theory of gold

"What's Xu Lang? Leave him a sigh of relief. I think he won't be able to attend this party anymore. Let's not wait for him!"

Yixue rolled her eyes in Xu Lang's direction, as if he had picked up the bargain.

"Yes, who told him to be speechless, he deserves it!" Li Yarou said with added jealousy.

"This..."

After all, this happened on his turf, and Yu Qing was a little embarrassed.

But he gritted his teeth and said, "Well, this is Xu Lang's provocation first, even if Uncle Xu asks about it, there is nothing to say. Let's still follow the original plan."

After Yu Qing decided not to be muddled, he greeted other people in the car and arranged for someone to send Xu Lang to the clinic.

Then he waited for a while for the few people who had just come out and didn't see the excitement, then set up the suspension vehicle and drove away.

...

Resplendent!

When Hanyu Xiaotian followed everyone into this super club, he couldn't help being shocked by its luxury.

As the name suggests, the clubhouse, from the inside to the outside, from the floor to the wall, is actually decorated with expensive objects such as gold, diamonds and various gems.

Gold has been one of the most valuable precious metals in human society since ancient times. As early as the Paleolithic age between 35,000 and 60,000 BC, there were remnants of gold mining in South Africa, located in Johannesburg. nearby.

And with the mining of gold, an ancient metropolis that existed 160,000 years ago was discovered!

These records can now be found in African Zulu legends.

However, the outside world is still puzzled that gold cannot be used as food, and because pure gold is too soft to be used as a tool, why mining gold was so important to the ancients?

In particular, the shafts dug by these ancients are as deep as 50 feet, which is highly technical.

There is also an interesting legend from the Sumerians: the creation of modern humans is not from God, but from some creatures from alien planets, out of the need of slave labor, that is, in ancient times, the ancients mining gold, is it possible to help foreigners? Star people mine, the ancients are just their slaves? This also triggered a lot of human thinking.

...

As we all know, gold is only the product of the explosion of dead stars in the universe.

When human beings left the solar system and stepped into the starry sky, gold appeared in human vision almost like Chinese cabbage, and it was once depreciated to a terrible level.

However, with the rapid development of human science and technology, people have discovered that some of the unique chemical properties of the gold element have been extremely widely used even today after humans entered the cosmic era.

For example, the chemical properties of gold are very stable, have excellent resistance to chemical corrosion and discoloration, can resist high temperatures, and are particularly stable in alkalis and various acids.

The density of gold element is also very large, it can easily compress a ton of gold into a fist-sized cube; gold is also the most malleable kind of metal, and 1 gram of gold can even be drawn into gold wires up to four kilometers long. It can also be hammered into gold leaf much thinner than paper...

Gold's various attributes have made it the darling of today's many high-tech industries and high-end manufacturing industries.

It can be made into superconductors, organic gold, and is widely used in high-tech industries, such as electronics, communications, chemical, medical and other fields.

So this result has led to the fact that although a large amount of gold exists in the universe, with the development and explosion of mankind, the amount of gold is still not enough for human consumption.

This makes the price of gold become tight and expensive again, and has also triggered people's gold rush in the vast universe. Even at the moment, there are many space companies operating gold rushes and making huge profits.
