Walk on a mountain path

Bathed in the dazzling sunshine, everyone shuttled through the mottled mountain forest, singing cheerful songs and striding towards the destination.

Looking at the familiar flowers and grasses, stones and trees in the mountains, these are the places where the friends used to play, and every time he sees the flowers and plants here, Zhang Feng will recall his beautiful childhood.

"Madman, look at this flower so beautiful......"

"Ahh......h

Liu Yiyi has lived in the city since she was a child, and rarely has such an opportunity to get close to nature, and she is very happy to see the flowers and trees in the mountains and forests.

Every time Zhang Feng smiled and patiently introduced to her, there are many kinds of flowers and trees in the mountains and forests, but this is difficult to help Zhang Feng is a native of the country, plus Zhang Feng liked biology the most when he was in middle school, and he also participated in biology competitions, and learned a lot of common animals and plants, so almost every animal and plant is like a treasure, just like a big encyclopedia, which makes the group admire.

"Is this an osmanthus tree??" Liu Yiyi once again carried forward the spirit of 'diligent study and inquisitive', and asked Zhang Feng.

"No! it's a wild eucommia ......."

"Oh, I know, grandpa often uses eucommia peel to cook and make soup......" Liu Yiyi immediately remembered when she heard the name.

"That's right, the skin and leaves of Eucommia are precious medicinal materials, and they are also the tonic that everyone usually uses when cooking, and even Eucommia can be made into tea!" Zhang Feng smiled and introduced to everyone.

"Hehe, Xiaofeng knows a lot, Eucommia is indeed a nourishing medicinal material, mainly has the effect of nourishing the lungs and kidneys, filling in the lean marrow............" Then the old man smiled and introduced several dishes that use Eucommia, such as Eucommia loincloth, Eucommia stewed chicken and so on.

The closer to the deep mountains, the more rugged and difficult the mountain road became, overgrown with weeds, and the dew was wet, so Zhang Feng had to walk in the forefront, using a firewood knife to cut through thorns and thorns, and cutting off the branches and leaves of trees that stretched too long, so that the looming mountain road was more smooth.

After walking for about ten minutes, the sound of spring water suddenly appeared in the mountains, and when we heard this sound, everyone suddenly became happy.

"Ah, the spring, there's a mountain spring over there......"

"Slow down, slow down, it's going to take a minute or two......

This is the case in the mountains, the empty mountains do not see people, but when you hear people's voices, even if you look at each other across the mountains, you can not reach them, this is what people often say that you can run dead horses in the mountains, and you don't see people when you hear the sound.

About a minute or two,

A clear mountain spring appeared in front of everyone's eyes, and the spring water flowed in the mountains, and the dense water vapor shrouded in the mountains, like a dream, it was as beautiful as a fairyland.

"Wow! What a beautiful mountain spring......" Seeing such a beautiful scenery, everyone couldn't help but sigh, it was really as beautiful as in the painting, and it was incomprehensible.

"Ahh......h

"Where, where let's see......" As soon as the little ones heard that there were small fish in the water, they ran over to watch, as if they were looking at some Western scenery, which was very rare.

"Crazy, can you drink the water here?" Liu Yiyi picked up a handful of water and asked Zhang Feng with an expectant face.

"It's okay to drink, the spring water here is sweet!" Zhang Feng smiled slightly, and he also drank the spring water with both hands.

After seeing it, everyone followed suit and drank happily.

"Ahh

"It's a rare and good mountain spring......"

"Yes, it's much better than the mineral water sold outside!"

Drinking the spring water in the mountains, everyone applauded, such a clear and natural sweet thirst-quenching mineral water is really very rare, the entire Guizhou Province is estimated to be in addition to Qinglong Mountain such a remote place, there is no second such a high-quality mountain spring.

"Ah, crystal, madman, do you want to see if this piece of mine is crystal?" Suddenly, the monkey exclaimed, as if he had found a guarantee, and excitedly asked Zhang Feng with a white stone the size of an egg.

"Hehe, what's so strange about this, crystals are very common in the mountains, and everyone can find them if you look carefully. Zhang Feng smiled, this thing is also called the star stone in the local area, and the legend is that the meteorite in the sky waved the meteor and fell to the ground to form a treasure.

"Xiao Feng brought it to me to take a look......" At this time, the old man was also interested, took this crystal and observed it carefully.

"Hehe, this is not a crystal, this should be calcite. The old man looked at it for a while and said with a smile.

"What?calcite??" Zhang Feng didn't expect that the crystal in his cognition had become calcite.

"Yes, crystal is a crystal of silica, and calcite is composed of calcium carbonate, and there is an essential difference between the two. ”

The old man smiled and continued to explain to everyone: "Look at this piece, whether it is a diamond-shaped crystal, as long as you knock hard, it will break down into square pieces, which is the origin of the name calcite." ”

"So that's ......" After listening to the old man's explanation, everyone suddenly realized, Zhang Feng felt that he was really knowledgeable, but he didn't expect that the star stone he knew since he was a child was not crystal but calcite.

"Is calcite worth much?" the monkey asked, a little apprehensive.

"Hahahaha...... You kid still want to make a fortune with this??" Hearing the monkey's words, the old man suddenly laughed, and suddenly the monkey felt that he had asked a very stupid question, this thing is not uncommon, if it was really valuable, it would have been picked up by the villagers a long time ago, how could it be his turn.

The old man smiled and continued: "Hehe, just pick this thing up and play with it, as far as I know, ordinary calcite ore is only about a hundred yuan a ton." ”

"One hundred pieces a ton ???" The monkey blinked in disbelief, calcite could be so cheap, isn't this just like ordinary stone?

Zhang Feng also felt incredible, he didn't expect this thing to be so cheap, it was simply the price of stones, not even the price of cabbage.

"Of course, calcite is not a gemstone, just an ordinary industrial raw material, and some of the toothpaste, floor tiles, cables, rubber and other things we usually use are added with calcite, which should play a role as a lubricant or something. The old man smiled and continued to explain.

"But to say that calcite is not worth much is not entirely correct, as long as the appearance is good and transparent, the price must be good, take our usual common strange stones, such as Taihu Lake Stone Yuhua Stone, these are just ordinary stones, but they have a peculiar appearance, in line with everyone's aesthetics, so the price is very high, so you can also look to see if there is a good-looking calcite, take it back and play is not bad!" The old man said with a smile.

Hearing the old man's explanation, everyone immediately understood, and they were looking for beautiful stones in the spring water.
