After two days of familiarization, Zhao Guangming and the lack of a door went to the place of outdoor equipment to learn outdoor knowledge.

Fan Yang, on the other hand, soaked in the library to check the information.

But the more you learn, the less timid you become, and only then do you know how reckless the three of them were to enter the valley to pan for gold.

I don't even have a bottle of anti-bear spray, so it's really bold and lucky to think about a few people.

This time, he completed all the necessary equipment, bought a few German-made sapper shovels, outdoor knives, Fan Yang soaked in the library for a few days, and finally bought a lot of books back, all about geography and geology.

On the third day, we set off again.

The compass in the car was too simple, this time I bought three more, one person was equipped with one, the appearance was very exquisite, and there was a lack of one to play with in my hand, and asked, "How do you use this thing?"

"Finding the way. Fan Yang replied.

"I said don't laugh, how do you divide the southeast, northwest?" asked the lack of a stupid question.

"Up north, down south, left west, right east, the compass does this, otherwise when you turn around, how can you tell the direction?

Fan Yang studied geography for a few days, and he still understood some of it, so he explained the lack of a subject.

"Oh, that's the truth, I see, this thing is fun. "Missing a toss and turn in the hand.

"Be careful, don't break it, it's best to put the compass horizontally, in case it breaks, it's troublesome. ”

The lack of one still doesn't attract attention.

Fan Yang snatched the compass: "Don't fool around, let's go in this time, there is no road in it at all, once you deviate from the river valley, encounter ice and snow areas, or forests, it is easy to get lost, if you can't determine the direction, you can't turn out for a few days, it's fun?"

"Well, what the hell is this thing for? If you get lost, you can find your way out with a compass?"

"Ever heard the story of Polaris?"

"Polaris? ”

"Yes, if you get lost in the forest, especially the desert, or the ocean, in the absence of a compass, you can rely on the North Star to determine the direction, it is the brightest star in the sky, you just have to face it, it is the north, let's put it this way, in the case of getting lost, what is the most fearful, do you know?"

"What is it?"

"It's a circle, people's perception behavior, is not guaranteed that you walk out of a straight line, you are obviously going north, but walking and walking, the southeast and northwest are not clear, especially the desert, and the ocean, you can't find the direction, you can be sure, you can't go out for the rest of your life, and then to put it another way, as long as you find the north, look for a direction to go, you walk out of a straight line, not a circle, then one day you can still go out, right?"

"Oh, that's what it means, I see. ”

Fan Yang said: "In the absence of a compass, relying on the North Star is one way, but maybe you can wait until the evening? What if there is no starless night? There is another way, which is simpler and more practical. ”

"What method?" asked Missing a Method.

"By the sun, the sun rises from the east and sets in the west, find a branch about one meter long, stick it vertically in the ground, and a shadow will appear, and the middle position of the shadow is the original coordinates, and the two ends of the straight line of the shadow point to the north and south, but which side is the south? Which side is the north? You can't tell the difference? You also need to make sure that something is there, and the method is very simple, first at the top of the shadow, mark it, after 15 minutes, because the sun's trajectory is moving westward, so the apex of the first shadow is west, and the second vertex after 15 minutes is east, understand?"

"Hehe, it's amazing, is this what you found in the library?"

"It's just common sense, you have to know more, otherwise a small direction is likely to kill you. Learn more about the outdoors, and in the event of an accident, you can greatly improve your chances of survival. Fan Yang said.

"Wouldn't you just do it? ”

"What if you get lost alone? I've thought about it, the first thing I do when I go in is to determine the location and direction of our gold mining shed, and then every time we go deep into a section of the road, we must set up action coordinates, this knowledge must be mastered by each of us, in case you get lost, relying on the direction, you can ensure that you are getting closer and closer to the base camp. ”

Zhao Guangming also said: "If you are told to learn, why are young people not motivated at all, you learn more from Fan Yang, do you hear? ”

"Hmm. "The lack of a door puts away the banter.

But the interest in chatting was aroused, and he asked again: "Fan Yang, tell us about it, what other interesting things have you learned these days?"

"Fun, fun, you go, my eyes are about to roll my short-sightedness, haven't you seen me buy so many books? Go in and read slowly, I can only learn slowly." ”

"Then where do you think it's better to find gold?" asked the lack of a subject.

"Where do I know, you have to ask my brother about this. ”

Missing a door to look at Zhao Guangming.

Zhao Guangming said: "Follow the Zakin Mountain and touch it, there must be it." ”

The two were entangled there for a long time, Zhao Guangming's knowledge was too general after all, it was all some experience passed down from generation to generation, and if you want to say that the scientific basis is pitiful.

According to Zhao Guangming, where there is water, there is gold.

Other than that, I can't say one, two, three.

I used to hear people in the coal mine say that coal is a tree, leaves, rotten and buried in the ground, and over time it will become coal, so how did you say gold?"

Zhao Guangming said: "Coal is a tree that rots and becomes a fart, coal is a rock, it is a kind of stone, and it doesn't make a draft if you brag about it, do you know jade?"

"Jade, how come I don't know. One was missing.

"Then why don't you say that jade grows on the ground?"

"Really, I, I may not lie to you, they really told me this, others are coal digging workers, maybe they don't know?"

Fan Yang smiled: "Brother, the lack of a door is right, as far as I know, coal is really formed by humus, the scientific truth is very complicated, at the same time, brother, the jade you said, is a stone, it is also right, jade itself is also a mineral, mainly the deposition of carbonate, resulting in a certain qualitative change in the stone, both of them make sense, don't argue." ”

The two of them gave up.

At the end, they asked in unison, "How was the gold formed?"

Fan Yang smiled again, to be honest, he was also an out-and-out illiterate, he didn't study for a few years, he ran away from society, plus his life in his previous life, Fan Yang didn't know how gold was formed.

After checking the information, I found out that the gold element was not actually formed on the earth, so I said according to the script: " You are all wrong, gold is not formed on the earth, it can't be changed, it is a meteorite from the sky brought to the earth, it is not like iron, it is not the original material of the earth, it is a meteorite in the universe, it falls to the earth, integrates into the core of the earth, and there is no more after digging, the gold we are mining now is the movement of the earth's crust, squeezing the gold in the center of the earth to the ground, so the distribution of gold, on the surface, is actually very extensive, but there is no trace, he is not like jade, he can judge the geography and geological conditions, whether it is possible to form jade under this rock, so the search for gold ore, compared with other mines, must be much more difficult, didn't dig it out, no one knows if there is gold underneath. ”

Zhao Guangming and the two of them seemed to understand whether they understood or not, and pondered for a long time: "Then you mean that those who are engaged in geology are not easy to find gold mines?"
