Under the blazing voice, the vultures are still hovering high above the Huvalgan River.

They were looking for food, but for a few days, it seemed that there was much less food, but they still did not want to leave, and waited, and their patience was always very strong.

A few hundred meters away from the factory, in a sand dune, there are two people lurking quietly in the sand and thorn bushes.

In the high-powered telescope, every move of the factory in the distance is under their surveillance.

"Unknown Target 9 appears, male, armed."

The two exchanged in a low voice, carefully taking pictures with a large focal length camera, and using PDA to transmit the sorted images.

Not only the two of them, but there are as many as three such monitoring points within a kilometer radius of the factory.

Day and night, there are people monitoring, tracking every car entering and leaving, recording every person entering and leaving, taking pictures, collecting, and summarizing.

All pieces of information were sent out.

……

What happened outside, Yang Tian didn't know, he just couldn't help but be curious, the expected counterattack did not come.

The remnants of the Cindy Free Front fighters were also purged by Pylokov and it was determined that none had survived.

Without the Cindy Freedom Front, Cindy's local area, the only one who can pose a threat to Yang Tian is Cindy's local political axe.

But no one showed up, not even a single patrolling policeman.

Everything was quiet and so quiet that it was confusing.

However, there was no counterattack, and Yang Tian was also happy to be leisurely, seizing this short time to carry out his own gold mining business.

The gold detector is not big.

It resembles a flat rice cooker, with an LCD screen on the front, a plastic case, and a few simple switches.

When things are made, Yang Tian doesn't plan to sell them, naturally everything is simple, and he doesn't think about the appearance or anything at all, put this thing on the wooden cart, and he can push it to work.

When connected to a power source, the gold detector is able to emit a magnetic field directly below at a depth of 10 meters.

Ten meters is an easy area to excavate, and the deeper it is, the more time it takes.

When the magnetic field is released, it will form a conical magnetic field space.

Based on the subtle differences in the magnetic field feedback, the content of various metals in the ground can be accurately distinguished.

There is a circuit board in the instrument, which will feedback a three-dimensional image of space similar to an ultrasonic diagram, a black and white picture, white is the filtered out of the soil, various dissimilar metal polymers, and black, is gold.

Of course, Yang Tian has also adjusted the precision of detection, and he will not be precise to the level of elements, but only to detect gold above a certain particle density.

Such a gold detector can accurately detect the amount of gold content and the distribution range of the underground.

If the gold density in an area is high enough, it can be excavated on a large scale and filtered as a whole.

The range of placer gold will be wide, and the location of the sediment will be different under geological changes.

With large machinery, it is possible to carry out large-scale excavation, but the purpose of the surname is too low, the accuracy of the surname is also poor, and Burgess is not stupid, of course, he knows the convenience of large-scale mechanical excavation.

But in the end, Boggs chose the more rudimentary manual purposeless excavation, the biggest reason being that it could not accurately locate the location of the placer.

The Huvalgan River is very long, digging without purpose, I don't know when it will be dug up, the surname Suo takes a simpler way, by hand, slowly digging.

But now that Yang Tian uses a gold detector, he can select a large area of gold concentration and excavate it purposefully.

Placer gold is different from mineral gold, placer gold is formed gold mixed into the geological layer, deposited, unlike mineral gold, there will be associated ores, but also special treatment, separation of associated ores.

Therefore, gold mining itself is a time-consuming and labor-intensive job, and there is no shortcut.

However, the gold detector greatly optimizes this process and makes the work easier.

Zhou Kai brought a total of 10 gold detectors, all of which are now in operation, with every kilometer of the Huvalgan River as a subdivision.

Ten gold detectors can detect ten kilometers of river channels.

Preliminary exploration work has been carried out for two days, and each dense area will be marked and the approximate extent will be circled.

Yang Tian is also collecting the information of ten gold detectors, collating and summarizing, and estimating the total gold content in the ten kilometers of the river.

Boggs's office has been cleared out, and Yang Tian looked at the information sorted out and calculated.

This kind of work can only be done by Yang Tian, and there is no large-scale computer on site for calculation, but Yang Tian has a brain that is more powerful than a computer.

"How's it going, it's gone?" Zhou Kai wiped a smelted gold brick, and it was gentle, as if his subordinates were touching a beautiful woman.

Yang Tian's arithmetic work is completely incredible in the eyes of outsiders.

I don't need a pen, I just keep looking at all kinds of detection images, and then I am in a daze, if it weren't for Yang Tian himself saying that he was estimating, the people who saw it would still think that he was dreaming in vain.

This estimation is extremely inaccurate, the placer gold particles are very small, the distribution is very scattered, and the surname of the dense ones may not be high, Yang Tian can only give a rough estimate, and then add them all together to determine a total value.

When he came back to his senses, Yang Tian scolded with a smile before he said in a low voice: "It's roughly estimated." ”

Zhou Kai immediately came to the spirit: "How many?" ”

Yang Tian would not hide Zhou Kai, stretched out a slap and shook it at Zhou Kai.

"Five tons?" Zhou Kai's eyes were violent, and a scream came out of his throat.

Yang Tian nodded, this number also exceeded his expectations.

The day after the capture of the factory, Yang Tian went to the Huvalgan River to check.

This channel, because of the change of topography, has a turn, and at the turn, a sedimentary area will be formed.

Boggs' main construction site is also in this turning area.

Yang Tian chose a detection area of seven kilometers upstream and three kilometers downstream and ten kilometers based on the turning area, which can basically include all the placer gold in this sedimentary area.

Because of geological changes, there will be relatively dense sedimentary areas in some parts of the river, which are difficult to find by aimless excavation, and only gold detectors can easily find them.

"So what are you waiting for, start, start! The more than 100 workers were already hungry and thirsty! Zhou Kai slapped the table excitedly and shouted first.

……

Cindy somewhere in a house.

A piece of information, intelligence, has been placed in front of Boggs.

In the room outside, there are notebooks, five or six people are controlling the computers, and the walls next to them are plastered with all kinds of printed data documents.

Satellite communicators have been set up and connected to headquarters.

With the authority of Boggs, a lot of information can be found.

And all this information is gathered in front of Boggs.

"Lizova, a Ukrainian national, majored in law at the University of St. Peter's Fort, joined the KGB in 2002, was sent on assignment in Western Europe, in '06, on a mission in Germany, failed in the mission, was accused of treason, and was confirmed dead."

Obviously, this death is going to be discounted, and it is fake.

"Pellokov, a former Alpha special forces, a native of Grozny, defected in 2004 and joined Chechen, and his situation is unknown."

"Andrew, German nationality, free mercenary, unknown information."

……

There is really not much useful information, in this group of people, except for Lizova, because she has an intelligence agent record, there is more information, and the rest of the people are all small people, who can find out their nationality and name, which is already good.

But Boggs wasn't satisfied.

Summing up, Boggs already has a rough understanding that it is Lizzova's mercenary army that attacks him.

Lizova's mercenary army is not well-known in Darfur Province, and there are many mercenaries of the same size, which are not under the supervision of their intelligence officers.

It is already rare to find out that Lizova escaped from El Fasher and went to Khartoum.

These people were obviously hired as mercenaries, and Boggs wanted revenge, and he would not look for them, he needed to know who was behind them.

And this person, obviously, has been determined.

Boggs picked up the top photo.

In the picture, there is a back, black hair, and it doesn't look tall, but Boggs speculates that it should be an Asian.

Because there is another Asian with a positive photo in the factory, there is no information, and I don't know what the origin is. In Khartoum, no useful information about this person could be found, and all the information about staying in the hotel was fake.

"Who the hell are you!"

Boggs said to himself, he knew that the owner of this back was the mastermind behind the theft of his own factory.
