"Because the chemical properties of gold are stable, generally do not react with other substances, so it exists in the sand and gravel in a free state, under the natural weathering, the rock is broken, and finally forms sand and soil, and the granular golden sand is buried in it, under the erosion and transportation of flowing water, the particles of sediment and gold move together with the water, and the speed and state of their movement are different, so in a certain area of the riverbed can form a rich zone of golden sand, which is the gold panning land that people are eager to find, and people set up gold panning equipment here, Dig the river sand into the gold panning bucket, and then pump the river water to flush the sand in the bucket, a large amount of sand will be carried away by the water, and what is left in the bucket is golden gold. For example, the Jinsha River in Sichuan is a famous gold mining zone, and it is said that a gold mining boat is worth a million, and the lucky gold digger can recoup the cost in a month.

Gold panning in ancient times was very difficult. Gold diggers first dig for sand, and then little by little put it into wooden panning tools to wash, using the characteristics of the gold ratio to wash away the sediment and leave the gold shavings. These golds tend to be the size of a needle tip or chaff. ”

Is the tip size okay?!

Fang Wenjing felt ...... It's time to say goodbye.

Like all the opportunities she has missed in ginseng for the past 32 years: all because of "Ah! This road sounds tiring, forget it! And missed. Only the juggling product dog who "understands everything, the door is plagued" and hides in his own safety zone is left.

"I really don't know what's going on in the domestic Internet circle now," she ran to the massage chair and crossed Erlang's legs and thought, "Maybe the awesome product managers are dead." I'll be able to get a job. Maybe the product manager died too much, and the living ones were all in demand. ”

Thinking about it like this, I feel that going back to Earth is not so scary.

"Ah, but the product managers are dying a lot, and the apes who work with them must be dying too...... No one writes code, so why do you want a product manager......"

After thinking about it, I felt that I was still a younger brother when I went back.

Alas, how to solve the worries! Only ...... That printed cannabis seed was left out for a few days to take a look!

Very good! The green shoots are growing well! It's like the grass in Wall-E.

The agricultural trio doesn't have much to do farm work now, practicing songs, practicing balls, and massages.

Fang Wenjing watched Youtube and Mike complained from time to time, almost once every two or three days, and both sides carefully tested each other's cooperation intentions through each other's expressions and tones in the video.

After chatting a little deeper, I found that the three views of the two are very different! It's the kind of big that can't be friends!

For example, he advised Fang Wenjing to keep exercising to avoid muscle atrophy and bone density loss caused by low gravity for a long time. Fang Wenjing retorted that he was going to return to Earth soon, and it didn't exist.

He also advised that it was better to keep exercising, which would help maintain mental health. Fang Wenjing: I have always been very healthy in my heart???

Mike: I think you're a bit aggressive.

Fang Wenjing: I think you have ADHD.

Mike: Hehe, I had it when I was a kid, and I remember when I was 9 years old...

Fang Wenjing: You also like to digress.

Mike:......

The shooter man, Fang Wenjing pouted, he had never been in tune with them (crossed his waist and slapped the table).

Ten weeks later, the first pig came out of the water, and they fed it some bags of milk from the Americans' broken tents, along with some leftovers.

In the eleventh week, the second pig also came out of the water, and both pigs were healthy, happy, safe and happy, and enjoyed themselves with the ducks.

Fang Wenjing showed Mike their videos, and Mike exclaimed, "So cute!" I want to come down and kiss them! Wow, the ducklings are so cute! ”

Two breeding pigs, Fang Wenjing, also gave names, one named Dalong and the other Xiaofeng. Pigweed is planted on the first floor of the greenhouse. She also forced the five and six children to catch one and kneel on the ground, and she consecrated them, wishing them more life and good nourishment.

Even if they're gone, the basement ecosystem will hopefully last for a while. Or simply leave a note for the U.S. military to explain the status of these two breeding pigs.

The only thing that hasn't been done now is to contact the motherland to send a boat to pick them up.

Stupid Li Li, did not give her any high-level contact information in China. Only the computer in the main control room has an internal communication software embedded in it, which can call and send text messages with one click. And now that the spaceship has been emptied, I used to use that computer, and I couldn't speak without oxygen.

In the fifteenth week, the devil knows what day of the week it is, and now she has to ask every time she chats with Mike what month it is, what day of the week it is, and how long the U.S. military will come.

On this day, she arranged a day to go out, and specially took the battery out to the spaceship to contact the organization. Arrange for the little five and six to go out to make some liquid oxygen and hydrogen to come back to replenish the water source.

I first read the email sent by the organization in the internal software, and the last one was October 1, 2029. The content is to urge her not to go down the wrong path and deviate from the track, and to establish contact with the organization as soon as possible.

She tilted her head and thought about it, and replied to the email:

"Dear Organization:

I am Fang Wenjing, the US military is coming to Mars to arrest me, I am afraid that I will not be able to stand the torture and confess state secrets, so I implore you to send a spacecraft to take me back to China.

I'm ——— now."

How do I write this, I'm on the Martian space station in the United States? Will you suspect that I have collaborated with the enemy and give up on me? How can I get them to pick me up? …………

"I am now on the Mars space station in the United States, and my space coordinates are:"

"Mike! What coordinates do I have our ship come to pick me up? Does your space station have a coordinate information similar to latitude and longitude? ”

"Well, no. Do you have? ”

"I haven't heard of it, I told you I'm not an astronaut, I stole a spaceship."

"I've said it, I'm — don't — believe it, don't believe a word."

"And how did your shuttle position the space station?"

"When you fly over, the radar scans it, and then it just flies in the right place."

“…… Is it so primitive? ”

"Where it's primitive, it's the same as car navigation."

“…… All right. ”

Continue writing:

"I'm now going to flee to the U.S. space station on Mars to escape the U.S. Army. If you don't come and pick me up, I'll starve to death on the space station.

Fang Wenjing.

Urgent.

P.S: Please send a reply to: fangwenjing@, this is the last time I'll use the ship's computer to send a message. ”

After writing the email, she felt satisfied and clicked "Send." ”

"Mike, I've emailed our government to ask them to pick me up!"

"Good," there was a rough gasp from there.

"Mike, are you jerking off?" Since she was sure that Mike couldn't talk to her, she easily classified him as a "friendzone" and a buddy.

"No, I'm lifting a barbell. Whew—"

"Hmph, your gym equipment is quite complete......" The first time she heard that there was a barbell, she couldn't hide the envy and jealousy in her words.

"Yes, whew—"

"Mike—?"

"Huh?" There was the sound of a barbell being put down.

"You—don't you miss home? Do you have family or friends? When are you going back? ”

"Uh, of course I have," came the hearty laugh of a shooter man. "I was supposed to go back this year. I've been in the sky for six years, and it's time for Kobe to take over the space station from me, but — you know that, so I don't know when I'll be able to go back now. ”

"Oh, won't NASA send someone else to replace you?"

"As long as I ask for it, it should be, but now is not the time to mention this, after all, we just lost four colleagues."

"yes, I understand." She stepped out of the ship and walked on the vast expanse leading to the basement.

"Happy? You're going back? The voice over there had a smile on it.

She was tempted to ask, did your mother know that you were always so happy? It's a pity that foreigners definitely don't understand this stalk.

"Well, I don't know."

Am I happy to go back?

She stopped and lay down, and pressed the Mp3 player that Xiao Wu borrowed through the spacesuit, and this outdated little machine was actually very useful in such a place where there was no Internet.

The headset came a folk song downloaded because of homesickness: "

Grew up in the Yinchuan-Suyang band

Lyrics: Su Yang

Composer: Su Yang

My family lives on the side of Tongxin Road

There was my father and mother

The water of the Yellow River

Flowing in the distance

Wind and sand have grown with me

Where did it come from?

Ask my mom and dad

Thousands of miles to the frontier

Life is too simple

Every year

Happiness is always ahead

The weeds on the side of the road kept growing

Greet the sun with me

And that summer was empty

I walked on the path

The weeds on the side of the road kept growing

Greet the sun with me

And that summer was empty

I walked on the path

Spring is here again

Autumn is often the case

The city is different

The girls are pretty

The road is also spacious

Winter is still wild

The wildflowers on the roadside kept growing

Greet the sun with me

And that summer was empty

I was walking down the road

The wildflowers on the roadside kept growing

Greet the sun with me

And that summer was empty

I was walking down the road

I can't see the rain

Look at the hope of this

I'm on the old path

I am in the sand

Birds flying

Fly over the field

I can't see the rain

Look at the hope of this

I'm on the old path

I am in the sand

Birds flying

Fly over the field

I can't see the rain

Look at the hope of this

I'm on the old path

I am in the sand

Birds flying

Fly over the field

I can't see the rain

Look at the hope of this

I'm on the old path

I am in the sand

Birds flying

Fly over the field

My family lives on the side of Tongxin Road

There was my father and mother

The water of the Yellow River

Flowing in the distance

Wind and sand have grown with me

The water of the Yellow River

Flowing in the distance

The wind and sand are growing with me~~~~
