Chen Ya's words made Pi Changshan stunned, and said with surprise on his face:

"How do you know?"

"Hehe, you don't care how I know. ”

The corners of Chen Ya's mouth twitched, and he couldn't help but look at him and said:

"Lao Pi is a big fool, don't listen to him. ”

Because the ancestor was a landlord, his grandfather left a few pieces of Yuan Datou, which are still kept at home, so Chen Ya has also studied it.

Ordinary 1 double Yuan Datou, although it has a wide range of circulation, in terms of the price of silver alone, it is indeed worth only about 300 yuan, but after all, it still has collection value.

It's worth more than a thousand dollars.

The silver dollar found by Jiu Jiu is a boutique version of the 'Flying Dragon' commemorative coin, which has a small circulation range and a price of about 10,000 yuan.

Even, some silver dollars, which are issued in smaller quantities, are worth hundreds of thousands or millions.

For example, in the late Qing Dynasty, the 'Great Dragon' silver dollar had a starting price of 100,000 RMB.

For another example, a 'Chinese Empire' commemorative coin in the collection of the Palace Museum is priced at 2.8 million.

Scarcity is expensive.

This is also the reason why Chen Ya and Lao Pi rushed up to check it out for the first time.

"Wow, so I picked up at least 10,000 dollars?"

Chirp happily, although ten thousand is not a lot, but it is worth making her happy, Chen Ya nodded and smiled:

"Luckily, you can look for it again, maybe there's more. ”

Hearing this, Jiu Jiu immediately ran to the water's edge and continued to search, while Lao Pi said with a depressed face:

"Xiaoqiang, if you see through it, do you understand?"

"I don't understand. ”

Chen Ya smiled, and the netizens in the live broadcast room were all excited, and they all shouted to look for it.

So, all three of them came to the river, rummaging for mud and sand, but unfortunately they didn't find anything afterwards, but the cold river water was really a little frozen.

It is located in the upper reaches of the Jinsha River, with an altitude of nearly 3,000 meters, and further up is the snow-capped mountains of the Qinghai-Tibet Plateau.

After looking for five or six minutes, and finding nothing, Jiu Jiu said with a regretful face:

"It's a pity to find some silver dollars. ”

"Let's go, go see the gold diggers. ”

Chen Ya said, first walked to a bend in the riverbed, and Jiu Jiu and Lao Pi naturally followed.

......

At this moment, Bandulin led five of his subordinates, who were hiding behind a hill on the bank of the river, staring at Chen Ya and the others.

Seeing Chen Ya on the riverbed, after walking into the distance, alopecia areata immediately ordered:

"Bring the rope and follow!"

Since both sides of the Jinsha River are hilly, except for the embankment next to the bridge, other places must use ropes to descend to the bottom of the riverbed.

In other words, the bald areata plan follows Chen Ya all the way, and when the other party is far away, he will go down to the bottom of the riverbed to kill this chiva kid!

After all, there are Huaxia police nearby, and no matter how bold they are, they don't dare to chase and kill Huaxia people under the noses of the police.

But as soon as the five of them left, a beggar with mud quickly ran over.

"Uncle Mei?"

Alopecia areata was a little surprised, and when Wu Daomei caught up, she said directly:

"Your father, let me help. ”

Hearing this, alopecia areata was overjoyed and said:

"Haha, that kid is dead!"

......

Returning to Chen Ya's side, the three of them came to the bend of the riverbed and immediately saw many Tibetan and Qiang gold diggers.

They were very focused on washing the sand and mud, and these gold diggers, some of them were men, women, and even children, and they were obviously locals in the vicinity.

Regarding Jinsha, Lao Pi briefly said a few words.

1. Natural golden sands are precipitated at the bottom of the riverbed, and usually the bend of the river is the most dense area of the golden sand, so the place where the river bends is often the most attractive to gold diggers.

Second, where there is a gold mine, you can find white quartz stone, which is an associated mine of gold, although it does not mean that where there is quartz, there must be gold.

But at least it shows that gold and quartz stone still have a certain connection.

......

Lao Pi's words made Chen Ya and Jiu Jiu look at the riverbed covered with pebbles, and sure enough, they found a lot of white stones.

Immediately after, the eyes of the three turned to the gold diggers who were working.

However, in addition to the traditional shovels and shovels, the most attractive thing is the gold panning.

It was a dark green plastic disc that looked a bit like a large saucer with ring-shaped threads all over the plate to serve as a sifting effect.

And at this moment, for Chen Ya's three people's viewing, those Tibetan and Qiang men didn't care, they were holding their trouser legs, standing in the cold river water, shaking the gold panning plate repeatedly.

The sediment in the tray is washed away, and the larger stones are discarded, and after repeated washing, some small stones with a large proportion and a small amount of sand are gradually left behind.

The small stones, about the size of soybeans, are brownish-yellow in appearance, reflecting a metallic luster, and obviously contain metallic components, or they are gravel with low gold content.

But these gravels are almost useless.

Then came the screening, and the gold diggers picked out all the gravel, either throwing them away or throwing them into the cloth bag, and when the old leather saw this, he couldn't help but say:

"Those stone gravel, the gold content is too low, the purity is mixed, and the significance of refining is not great, but there are also people who accept it. ”

It has been said before that some tourist attractions, in order to create gimmicks, will buy a large number of golden sands, which is the kind of gold-containing residue bought.

These residues, although golden, are not valuable.

For a few hundred dollars, you can buy several catties.

After all, there are several processes in the process of refining gold, and chemicals are also used, if this gold-containing residue is refined, although gold can also be purified, but I am afraid that the cost will not be earned.

Therefore, it can only be sold.

But in any case, this is also an extra income.

Of course!

If you're lucky, you'll be able to find gold in the gravel.

"Haha, gold!"

However, a Tibetan man smiled, but found a grain of gold the size of a grain of rice from the gold panning plate, although it was small, but for the gold diggers, it was an unexpected joy.

The weight of gold, which is the size of a grain of rice and weighs about half a gram, is not in vain.

And at this time, the gold panning work is also the time to see the real chapter.

After sifting out the gravel, continue to wash until a fine layer of sand remains in the pan.

The color of the sand was generally grayish-black, and most of the gold diggers were disappointed, apparently finding nothing.

But some of the gold diggers smiled, because in their gold panning plates, there were some small grains of sand, but they were golden colors.

Obviously, this is the higher purity of the golden sand.

Although in the end, the golden sand is pitiful, but everyone understands the truth that a little adds up.

After repeated washing, the gold panning plate was finally left with dots of golden sand, and those sweaty Tibetan and Qiang men immediately collected it in a glass bottle.

Under the sunlight, a light layer of gold appeared in the transparent glass bottle, which was really dazzling.

"It's itchy to watch. ”

Chirp with envy, Chen Ya couldn't help but smile and said:

"We're still looking around, maybe we really found a dog's head. ”

Chen Ya is not envious of the gold diggers, after all, it is normal for people to pay for their labor and be rewarded, and this work is too time-consuming.

Using these simple tools, it is estimated that you can find more than a dozen grams of golden sands after a busy day, which is good!

Of course, what really caught Chen Ya's attention was that these gold diggers would use shovels to fill in the excavated area when they needed to change the location after digging the riverbed.

This is the rule that gold diggers abide by each other.

Destruction of the riverbed is not allowed!

Before changing the location, the excavated riverbed must be filled in to protect the Jinsha River from potholes.

Immediately afterward, the three of them continued on foot and began to search the riverbed, hoping to find the dog's head gold.

Among them, Lao Pi walked up to the gold diggers and started talking in Tibetan, as if asking for something.

Chen Ya glanced at it and didn't care, but the tweeter beside him suddenly looked up into the distance and found that there were three small black spots on the riverbed more than ten kilometers away, so he said curiously:

"What's that?"

Due to the high altitude, the pure air, and the surrounding area is extremely empty, the naked eye of human beings can still see the scene more than ten kilometers away.

Hearing this, Chen Ya raised his eyes and found that the distance was too far, so he turned on the Super Eagle Eye.

In the next second, Chen Ya's sharp gaze saw the picture more than ten kilometers away.

However, I saw that the three wooden boats, each parked in a different position, had a conveyor belt on the boat, constantly transporting the sand and mud in the river, and there were rocks like hills piled up around them.

"It's ...... Illegal gold mining vessels?"

Chen Ya frowned, he didn't have to think about it to know that compared with the gold diggers, these three gold mining ships and cliffs were illegal.

Indeed, the riverbed where the gold mining ship is located has long been destroyed beyond recognition.

On the river channel more than 600 meters wide, there are potholes everywhere, and stone mountains are piled up, such a messy picture is really unsightly.

It was as if Jinshajiang was wailing, silently accusing the lawbreakers of their behavior.

"It's a gold mining ship?"

Jiu Jiu's face changed, and he immediately picked up his mobile phone and said:

"Call the police!"

However, as soon as he finished speaking, Lao Pi walked back, shook his head and said:

"Is there a fart for calling the police? By the time the police pass, those gold mining boats would have run away a long time ago!"

As he spoke, Lao Pi looked at the three black dots in the distance, and could only sigh:

"We can't control this!"

Indeed, since people dare to blatantly mine gold, there is obviously a way, and they are not afraid of the police.

Chen Ya felt a little unhappy in his heart, but he didn't seem to be able to control it, until he was in the state of Eagle Eye, his eyes swept away, and he suddenly saw that on the hills on the bank of the river, there were actually a few people quietly poking their heads out.

Hey, mud monkeys?

Seeing the alopecia areata in it, staring at him viciously, Chen Ya couldn't help but show a smile, it seemed that this guy was here to seek revenge.

In the next second, Chen Ya glanced at the three illegal gold mining ships in the distance, so he couldn't help but laugh:

"Don't call the police, I have a way to get rid of the gold mining ship at once. ”

......
