"project?"

"Well, yes, they are some rich people from the Dragon Kingdom. They have a unique hobby for their own yards."

"For example, the trails in the yard must be paved with regular cobblestones, so..."

Neil smiled: "I understand."

"Okay, how long you want to use it will be calculated as one hundred and fifty days."

"One week!"

Chen Rui thought for a while and said.

In fact, what Chen Rui wants to do is to collect all the dust in those rollers and then try to make alchemy.

So there is no need to rent for too long.

But he was afraid that people would not rent it to him if he only rented it for a day or two, so he just gritted his teeth and rented it for a week.

Neil thought for a while: "No problem, 1,050 yuan, but you have to pay an extra 500 deposit."

"Deal, by the way, that Dodge pickup truck of yours, do you want to rent it..."

Chen Rui spent a total of 2,000 not only to rent the gravel crusher, but also an old pickup truck.

After spending 2,000 yuan, he only had 1,000 yuan left.

Due to problems with his family's business, he sent all his savings back to China.

In addition, he was laid off by the company some time ago and he had a car accident, so his current situation is extremely tight.

Whether he can turn over or not depends on this shot.

Now that his home is gone, he can't afford to stay in a hotel, not even the cheapest motel.

That place costs more than 100 yuan a night, and the security and environment are not very good.

So for him, the most important issue now is to find a place to stay.

After all, Chen Rui has lived in the United States for more than ten years, so he still has this life experience.

He drove the pickup truck and towed the gravel crusher and headed straight to Bonita Ranch.

Bonita Ranch is not a real ranch, but an RV campground in the small town of Fontana.

Not only are there many tourists towing RVs here, there are also RVs for rent...

Arriving at the campground, Chen Rui quickly found an Anita RV rental company.

"Single rental is 75 yuan a day, long-term rental is 350 yuan a week, water and electricity are not included..."

The boss of the company is a fat aunt who smokes constantly and has a waistline of four feet.

After learning about Chen Rui's purpose, he took him to see a trailer-type RV.

The RV can be about eight square meters, but it is a bit shabby due to its age.

Fortunately, although the house is small, it is fully equipped with a large bed, dining table and kitchen.

There is even a separate bathroom in the southeast corner of the RV.

Chen Rui was very satisfied with the price of the RV and immediately decided to rent it.

“Let’s rent it for a week first.”

Chen Rui paid the rent, and his aunt happily issued him a receipt.

After the aunt left, Chen Rui went straight to the stone crusher and got into the stone crusher.

There is a thick layer of mud at the bottom of the roller and a thick layer of scale.

Chen Rui knew that this was the result of flooding.

In the early years, the Yukon River Delta in Alaska was a famous gold-producing area.

It is said that when you were panning for gold two hundred years ago, you could see the glittering golden sand at the bottom of the river bed just by standing by the river.

But after being plundered by people for two hundred years, it is naturally impossible to mine gold as easily as before.

But what if you still want to try your luck?

Then you can only go to technology!

Among these technological activities, the simplest is this kind of stone crusher.

Just throw all the stones by the river that are suspected of containing gold into a gravel machine and crush them.

Then rinse it with water continuously. If you are lucky, you can get golden sand...

What Chen Rui is betting on now is the remaining sand in the roller.

And the soil in the inner wall and outer cylinder is high-grade gold ore soil.

After banging on the roller all afternoon, Chen Rui finally cleaned out the dirt between the inner wall of the roller and the interlayer.

The soil weighed more than ten kilograms, and Chen Rui carefully transported the soil back to his RV.

Then he locked the door and drove straight to the nearby building materials supermarket, regardless of how late it was.

Once inside, I directly purchased various alchemical equipment such as spray guns and crucibles.

Not caring about being hungry, he rushed back and started refining.

First, throw all the soil impurities into the acidic solution he prepared.

These solutions can dissolve all the metal minerals in the soil.

While sprinkling the soil into the solution, Chen Rui also used a glass rod to stir continuously.

Wait until the solution is completely turbid, then adjust the pH value of the solution according to a certain proportion.

In this way, the different minerals contained in it will be stratified.

Afterwards, Chen Rui put zinc wire into the acidic solution.

A large number of bubbles are quickly generated in the glass container, and the zinc will displace the gold in the solution.

When he saw that the zinc wire had completely turned black, Chen Rui couldn't help but look up to the sky and laugh wildly.

After taking a look at the bag of sand under my feet, where is the red light shining?

That is clearly the legendary jewel!

But at this time, he wanted to sincerely thank his high school chemistry teacher, if he hadn't forced him so hard back then.

I am afraid that I have long forgotten these basic chemical knowledge.

Take out those zinc wires, put them into another glass beaker, and add the electrolyte.

The blackened zinc wire quickly undergoes an ionization reaction, and the gold attached to the zinc wire precipitates.

However, the gold at this time was not as golden as everyone thought, but instead was completely black.

At this time, because the gold still has many impurities, its purity is not high.

The next step is to remove impurities. This process is simple, just burn it in the crucible...

After a busy night, Master Chen finally finished refining all the 'gold soil' at dawn.

He got a total of 9 ounces of gold!

How much gold can be obtained from more than ten kilograms of soil shows how high-grade the gold mines found by gold diggers were.

Of course, there is another reason, and that is that the gold diggers have helped him complete the work of scouring the sand in the big waves before.

Maybe dozens of tons of sediment have been washed away before...

I took out my mobile phone and checked today's gold price. Because the Bank of the United States has been hit hard recently, the price of gold has now rocketed.

Chen Rui's eyes lit up when he saw that one ounce of gold had exceeded the $2,000 mark last night.

He took off his gas mask and sat down on the bed. Unable to hold himself up any longer, he fell on the bed and fell into a deep sleep.

When I opened my eyes again, it was already past two o'clock in the afternoon.

He still woke up from hunger, and then he remembered that he hadn't eaten much all day and night.

Carrying a few small goldfish that he had made on his body, Chen Rui got out of the RV.

Passing by a convenience store, he bought a bottle of milk and drove straight to Beverly without even bothering to eat.

When he was checking the news just now, he saw that there had been runs on many banks in recent days.

Also, various gold coins and gold are now the most popular commodities in the United States.

Americans are not stupid. Everyone knows that cryptocurrencies are not safe now, and those digital currencies are also castles in the air.

Anyone with some wealth began to hoard gold crazily.
