"Gunshots?" Fan Yang raised his head and looked at the sky.

Zhao Guangming distinguished: "It seems to be a shotgun, right? Could it be that someone is hunting? No, it must be a foreigner, is it poaching?" Hey, let's be careful and hide first." ”

Zhao Guangming was a little flustered.

I was just thinking about it, but I heard a gunshot from Pia, Pia, Pia in the valley.

Even Fan Yang hesitated.

I heard two shots in a row, and it was sure that it was a gunshot.

One pulled a missing door and hurriedly squatted down.

Several people pricked up their ears and listened for a while, but there was no movement.

"What should I do?" Zhao Guangming asked.

Deep in the mountains and valleys, two gunshots were heard.

You must know that this river valley is inaccessible, and this place is quite remote, in front of the Tagong grassland, the Tagong grassland is rich in water and grass, the herdsmen do not come here at all, behind the bare snow mountain, this forest valley, is also red pine spruce, overgrown with rocks, deserted, except for rabbits, marmots, even wolves do not want to come.

It's like a barren mountain.

What can be picked inside is a little fungus, and there is only occasional sparse turf on the hillside.

They had been digging for gold for two months, and they didn't even see a ghost.

This time, I walked in the river valley for three days, and there was no one in sight.

These two gunshots were too alarming.

"Why don't we go back?" Zhao Guangming said again.

"How is it possible?" Fan Yang immediately refused.

They have worked so hard to get to the foot of the mountain, how can they go back?

Fan Yang pondered for a while and asked, "You just said that you are definitely a foreigner? What is going on? Could it be a herdsman?"

Zhao Guangming shook his head: "No, you don't know the habits of herdsmen, the herdsmen in Tibetan areas don't hunt, in this ravine, in addition to poaching, who else will there be?"

"Poaching, what are they stealing?" asked Missing.

"I don't know, it could be a wild yak, it could be a goat, it's dangerous. ”

"Wild yaks? We didn't see any along the way. Fan Yang asked.

"What do you know, these wild yaks, all walking on the top of the mountain, the herdsmen also have to kowtow when they see it, just like Dapeng, they are all the mounts of the Bodhisattva, and the hair on their stomachs can be dragged to the ground, and they can manage thousands at a time. ”

Fan Yang recalled his previous life, as if he had heard this kind of statement.

"Then you mean that there may be wild yaks on Zakin Mountain?"

Zhao Guangming's eyes glared: "How do I know, what should I do?"

"How could it be. Fan Yang refused.

He also said: "What does it matter to us that they beat his yak? Let's just walk around, in case we run into it, if you are afraid, I will go up and negotiate." ”

"You negotiate a fart, aren't you afraid that others will kill people?" Zhao Guangming scolded.

"Hehe, you've really watched too many movies, it's not that serious, let's go, you've come here, you may not be able to go back?

Fan Yang looked at the Zakin Mountain not far away, the main peak was clearly visible, and there were still a few kilometers at most, and he could reach the foot of the mountain, and there was no reason to turn back at this time.

In the past three days, they have advanced more than 10 kilometers along the winding river channel.

Along the way, Zhao Guangming gradually explained the secret of finding gold.

It turns out that looking for gold along the river is simple, but in fact it is also very simple, first of all, look for the river beach.

The rivers are all meandering, because of the trend of the mountains, the topography, the impact of the water and so on, the rivers are destined to meander forward.

And how is the sediment deposited?

It's like the alluvial bed and sedimentary bed that Zhao Guangming said.

An alluvial bed is a sediment that is pushed by water to both banks, and when it encounters a flat terrain, it will form a piled sandy beach, or stone beach.

This is called a river beach.

In order to form a river beach, first of all, the terrain must be gentle enough, and the water surface must be wide enough, and there must be a process of rising water and falling into the water.

And what is a sedimentary bed?

It can be simply seen as the place where the river bends.

When the river bends, the force of the water will cause a large amount of pebbles and sediment to be deposited, and it will only be deposited on one bank, so the amount is much larger than the alluvial beds on both banks.

One bend sinks to the left bank, then another bend sinks to the right bank, and so on.

These twists and turns, the so-called nine bends and eight bends into gold pits, whether it is gold panning, or sand mining, the more gulf streams in the river, the better.

For example, in the course of three days, they found a total of five beaches on this more than 10-kilometer-long stretch of river.

Like the tidal flat I found on the first day, there are 5 river beaches, and after a trial wash, all of them are gold.

However, the difficulty of mining is higher than the other.

How much gold is there? But each one is lower than the other.

There is a simple truth, the sand downstream must be washed down from the upstream.

Fan Yanghe lacks a door, two laymen, and it is natural to think that there must be more Jinsha in the upstream than in the downstream.

was splashed with cold water by Zhao Guangming.

The opposite is true.

The gold content downstream is usually higher than that upstream, and much higher.

Why?

First of all, it has to do with the amount of river sand.

Because of the large pebbles, the first few Gulf Streams are stopped, and the front Gulf Stream is not large, and it is surrounded by wavy rings, a total of 5 Gulf Streams, to form a natural pure sand bed.

And in the last Gulf Stream, that is, the old pit that Fan Yang and they had scoured all over again, the place where the river bends, has an angle of 110 degrees, almost a right-angle bend.

The sand only stood up until it was here.

The pile was as deep as 6 meters.

The deeper the pile, the more the sand will be deposited.

For gold panning or sand mining, this terrain is undoubtedly the best.

There are too few Gulf Streams in front, so this kind of place is not a pure sand bed, but a pebble beach.

If there are only two or three Gulf Streams, the pebbles in front of you are not blocked clean enough, and the sand and gravel are mined.

The meandering of the river is also a natural washing process.

And the higher you go, the shallower the accumulation of the sand layer, although there is gold in the several river beaches found behind, but the sedimentation is not deep enough, at most two or three meters, and a shovel down, most of them are even sand and gravel.

Relying on manual excavation, the difficulty has increased by more than a little bit.

It is almost impossible to dig a pit up to 6 meters deep like that old pit again.

The mood of the three of them was both excited and apprehensive.

I found 5 river beaches in a row, and there was gold.

Although it is difficult to mine, as long as you are willing to endure hardships, the big deal is that the harvest is a little worse, and it will be possible to dry for two or three months next year, and it will still be possible to ensure the harvest in drought and flood.

Another point is that there must be a golden vein in this whole section of the river, it is certain.

However, it is impossible to determine where the deposit is in the more than 10-kilometer-long section of the river.

It's the same very simple truth, the sand downstream must be washed down from the upstream.

Wherever you go, the sand in the river is no longer gold, but it is easy to judge.

Pinching the head and removing the tail can somewhat reduce some of the judgment range.

At that time, Zhao Guangming still has the ability to watch the mountains and look at the shape, and there is a high probability that he can determine the approximate location of the deposit.

Unexpectedly, I walked to the foot of the mountain quickly, and found 5 river beaches in a row, all of which still had gold.

That means that the original deposit has to go up.

Do you really want to go deep into the interior of Zakin Mountain?

So the three of them were both excited and apprehensive.

At this time, Zhao Guangming actually shouted to go back?

How can it be?
