However, if the raw materials of the Ming Dynasty and the paper were used to print the grain stamps, it was guaranteed that one kilogram written on them would be exchanged for one kilogram of grain. Zhu Zilong thought about it, and felt that he might lose all his pants!

In all dynasties, there are countless imitations of counterfeit currency.

If there is no strong technology, with the printing technology of the Ming Dynasty, it is extremely easy to have fake food stamps.

When the time comes, people will cheat Zhu Zilong out of a large amount of grain and grass with a fake exchange, who will he cry to?

So, just like the banknotes of later generations, he must be absolutely ahead of the curve, so that outside counterfeiters can't counterfeit at all.

This method of prevention is difficult for others. The treasure banknotes of the Ming Dynasty are about to be broken now!

However, for Zhu Zilong, who can cross, it is not too difficult.

He only needs to go back to the modern 21st century and buy a few, oh no, dozens or hundreds of old-fashioned printing presses after 1900 and even after the founding of New China, or simply use photocopiers to print the grain stamps used by the Ming Dynasty.

Hundreds of years of technology and machinery beyond this plane, no one can imitate his food stamps.

It can be truly 100 percent, and every food stamp is real.

With this idea in mind, Zhu Zilong calculated the time and decided to go back to the modern side of the 21st century again.

In the middle, he secretly entered the Dongsheng Divine Continent once, and secretly observed the survivors in the World Tree, and had a good time.

Without alarming them, he quietly retreated.

After turning around, Zhu Zilong, who already had many flamethrowers in the Dragon Ball space, came to the mountain-like dog-headed gold edge of Dongsheng Divine Continent.

Looking at this dog-headed Jin Xiaoshan, who is known to be worth 300 billion yuan, Zhu Zilong's mood became entangled again.

More than 300 billion yuan of dog-headed Jin Xiaoshan, my mother!

As long as this thing is moved back to the human world, the position of the world's richest man in the 21st century will have to be changed, right?

Well, wait, maybe it can't be changed yet.

Zhu Zilong, who forcibly calmed down, began to recall a lot of information.

According to the "Hurun World Rich List", Biel Gates re-became the richest man in the Hurun world rich list after N years with 410 billion.

Warren Buffett ranked second with 380 billion. ******, the richest man in mainland China, ranked 26th with 150 billion, and Li Jiacheng ranked 12th with 200 billion.

There are a lot of rich people.

If you take Comrade NO1 Gates as an example, his net worth is more than 81 billion US dollars, and people can earn 128 to 200 US dollars per second (nearly 2,000 yuan per second) when they collect interest, which is about 4.1 billion US dollars per year.

Suppose you can throw 4 bills per second, light a cigarette or throw it on the ground, and you can throw more than 81 billion dollars until the end of the world or the day when humanity will end, in short, very rich, very rich!

This is still a new generation of rich people on the surface, and many families who like to make a fortune in a low-key way are more beef than others.

For example, as early as around 1856, the Rothschilds had amassed a total fortune equivalent to $6 billion. $6 billion more than a hundred years ago is definitely worth more than trillions now!

And if calculated at an annual rate of return of 6%, their family's assets today are at least more than 50 trillion US dollars, which is 1,000 times the assets of Gaiji.

Of course, there may be investment mistakes in them, but in short, there are really many people and families who are secretly rich in the human world. Therefore, 300 billion yuan seems to be a lot when you think about it, but in fact, when you look at it all over the world, it is only a small wave.

If you compare it with the wealth of the country, it is even worse than wool.

For example, the annual GDP of Huaxia is nearly 100 billion yuan. Tax revenue alone is 12 trillion a year!

And the GDP of the United States X country is also more than tens of trillion US dollars a year, don't think it is not much, it has to increase by 6 to 7 times when converted into RMB, that is, hundreds of billions of income. And their taxes there go even further, and you only have to contribute a third of your income to taxes every year!

Well, stop. Now it's time to talk about kotou gold!

Can this thing really be shipped back?

Zhu Zilong twitched the corners of his mouth, it is not a question of how many tons of weight, but how to explain the human world transported back to the 21st century?

Said it was picked up? Who believes TM?

The human world has developed to this day, except for the Dragon Triangle and Bermuda, and a few deserts and other places, other people and countries have occupied everywhere. This is the place where there is a Lord!

Where can I pick it up?

No matter where it is named, it is estimated that there will be a country or organization that will jump out and say that it is their thing. They are the masters!

It would be even worse if you said that you picked it up in China or on some Chinese island. The five-hundred-dollar prize and the small medal may be on the way, rushing towards him. Sweat!

Said it was picked up abroad? That may be barely said in the past, for example, in X or third world countries.

However, according to international practice, I only have to fight a lawsuit for a long time, and I have to pay about half of the dog's head gold or about half of the income as the tax of the original owner (Western countries).

That is, it will be reduced by half out of thin air, and more than 150 billion yuan of money will go to others.

Either way, it's going to feel super uncomfortable.

Moreover, if you don't have the support of strong force on the surface, you don't want to expose yourself.

It is conceivable that even if half of the tax is paid, I still have about 150 billion left, and I am afraid that this day will not be easy.

You have to hire hundreds of bodyguards alone, and going out is like Galeries Lafayette going to the street, and being at home is like going to prison, and you have completely lost your freedom.

Then it's still a joke, no matter how rich it is, it's a fart?

Chinese people who win the five million welfare lottery will wear a mask or pretend to be a gray wolf before going to receive the prize. If Zhu Zilong is on the news and says that he will go home with 150 billion, it is really unimaginable. There will never be peace in the future!

Strong wealth must be legal, time, power, and protection, and it must not be too eye-catching to the point of getting out of control.

Otherwise, there will be endless troubles and endless troubles!

This is the truth and lesson that countless predecessors have exchanged for with their blood!

I felt that I still couldn't carry this thing back to the modern Zhu Zilong, so I had to focus on the underground gold mine.

He quietly walked away, searched around the mining area, and finally found a small piece of exposed ore in an open area.

At this time, Zhu Zilong also took some equipment in his hands. Even if it can't be as accurate as a professional factory in the modern human world, it can also check 70% of the general ore structure composition.

Soon, the data came out.

If all the gold ore below were of this standard, then each ton of gold ore would yield nearly 100 or more than 100 grams of pure gold.

In the 21st century, a ton of raw ore can extract a few grams of pure gold, which can be called gold ore. Now this gold ore ingredient can be regarded as the best ore in the human world!

Judging from the situation in the future in 2020, gold is less than one billionth of a billion in the earth's crustal rocks, and looking for gold is to find rocks with a content of one part per million, that is, one gram of gold in one ton of rock, which is basically considered a mine.

The appearance of ordinary gold ore is not much different from ordinary granite, in fact, its "gold grade" (referring to the gold content per 100 grams of gold ore) is more than 2,000 times that of ordinary stone. It's qualified!

Most of the average grade of domestic gold mines is below 5 grams or even 2 grams (grams per ton), which used to be relatively high, but now there are few rich ores. The average grade of gold ore abroad, especially in Africa, is generally between 2-15 grams, but some ores can even reach tens or even hundreds of grams.

Generally, manual excavation of placer gold ore only exists in some small profitable ore bodies, and the ore body grade is more than 0.02 g/m3 can be profitable.

Wait, in the old American gold rush era, many people were looking for gold and golden sand in the riverbed.

There's also a river nearby, could it?

So, not long after, Zhu Zilong, who thought of this, appeared by the nearby river.

After searching carefully for a few minutes, I found many grains like gold sand, but the gold and a lot of sand were mixed together, and it was necessary to dig for gold seriously.

Gold panning refers to the fact that gold diggers have recovered the silt from the river or lake, and then washed the silt in the pan in order to find the natural golden sand in the silt. Gold panning was once a means of getting rich in the eyes of many adventurers, and there have been several gold rushes in history.

For example, in the early nineteenth century, the United States embarked on a westward expansion campaign, and groups of adventurers advanced to the west coast of the Pacific Ocean. When news of the discovery of gold in California was confirmed, another wave of immigration was triggered, and people flocked to San Francisco to put aside their jobs and try to make their dreams of gold come true.

Because the golden sand is on the riverbed, gold can be washed out of the sand with just an ordinary washbasin. At that time, the average person earned twenty dollars a day, which was twenty times the daily wage of workers in the eastern United States. In a bonanza area, the per capita daily income is $2,000.

Zhu Zilong walked into the river, the more he looked at it, the more frightened he became, there was too much sand gold in the riverbed and sand, as long as he could dig them all out in time, it was even more crazy than the Jinsha River in the United States-
