"What? Not worth it? Liu Biao was shocked.

"Sister Snow Lotus, this is the ore of the Night Pearl! Is it impossible not to put it worthlessly? Zhang Yun is also anxious, he has an indicator of fifty cars, if it is not worth it, then the loss will be big.

"Yes, hehe, Sister Xuelian, why is it worthless? The pearl of the night is priceless, it is said. The value of a night pearl smaller than an egg in the mouth of the Empress Dowager Cixi is unlimited, the ore here looks very large, and it is not difficult to polish a night pearl larger than a basketball with an ore, it is impossible not to be valuable, right? ”

Wang Feng also looked puzzled, in fact, not only he was puzzled, but he was a little puzzled, because, according to historical records, the Night Pearl was a valuable treasure, and in ancient times, there were countless troops who fought for a Night Pearl.

"The Night Pearl is an ore called 'glowstone', which is not a rare industrial raw material, and its value can only be determined by the market, and some newspaper hype is a bit exaggerated. In terms of the constituent elements of the Night Pearl, it is just an ordinary ore composed of calcium fluoride, and the amount of its storage should be measured in 100 million tons, whether in terms of industrial use or storage value, the Night Pearl cannot be compared with gold...... "Speaking of at least about ore, the girl's face was confident, as if she had changed a person.

"100 million tons!"

Liu Biao has an urge to vomit blood and die, no matter what it is, if it is more than enough to be calculated in the unit of "100 million tons", it will definitely not be valuable, if the gold and gems are also calculated in the unit of "100 million tons", it is estimated that it will not be worth much, and it is not possible that the bowl of a farmer's family for dinner may be made of gold......

"In fact, 100 million tons to calculate may be a conservative estimate, this kind of ore is too ordinary, just because there is no mining value, many people ignore it, did not attract the attention of the public, in fact, the night pearl is fluorstone, because it contains a variety of rare elements and often purple red, emerald green, light blue, colorless transparent fluorite is rare. When you put the glowstone under an ultraviolet fluorescent lamp, it will fluoresce beautifully. ”

According to modern data, there are more than 20 kinds of minerals in nature, such as crystal, diamond, glowstone, etc. They are able to emit visible light in response to the emission of foreign energy, which is caused by the formation of so-called 'luminescent centers' when the rare earth elements from these minerals enter the crystal lattice during crystallization. This glowing surname is clearly manifested in the weak day and strong night, which is commonly referred to as 'night light'...... "The girl talks eloquently, completely without the tension at the beginning."

"Little rabbit cub, forget it, these hundreds of millions of tons of night pearl Uncle Biao will be given to you, hey......" Liu Biao looked sad, and with a wave of his hand, he gave Zhang Yun the ore in the entire karst cave.

"Brother Biao, you are so generous! Thank you Uncle Biao for your kindness, I can pull ten carts and eight carts and throw them into my fish pond. Zhang Yun scoffed at Liu Biao's generosity.

"By the way, these glowstones are supposed to be colorless and transparent?" Zhang Yang approached the wall and observed the road from several angles.

"Well, the quality of these glowstones is relatively high, and the demand for this raw material in handicrafts is very large......" The girl nodded in affirmation after carefully observing it with a magnifying glass.

"Hah...... In high demand? Liu Biao's eyes immediately burst into golden light, this guy has been thinking about getting something for nothing for a long time, and he dreams that the gold will fall on the bed.

"Well, if there is enough money to develop it, the value of these glowstones is still considerable."

"Hahaha...... I'm rich......" Zhang Yun suddenly jumped up on one leg and screamed on the wall.

"Hey...... What do you get rich? Liu Biao ran over and pulled Zhang Yun away, preventing him from touching his precious glowstone.

"I remember, you just said, little rabbit cub, forget it, these hundreds of millions of tons of night pearl Uncle Biao will be given to you......" Zhang Yun looked at Liu Biao with wide eyes.

"Damn, I'll just say that you are serious, and besides, you also said, you only need to throw ten carts and eight carts in your fish pond." Liu Biao slapped Zhang Yun to the ground.

"Count you ruthless! It's not ten cars or eight cars, it's fifty cars! Zhang Yun covered his head with one hand and touched his injured leg with the other, hurting his teeth.

"Fifty cars is about the same, hehe......" Liu Biao smiled, the current Zhang Yun is a small bowl of food for him, and he can be bullied whenever he wants.

Zhang Yun is in pain now, regretting that he began to offend Uncle Biao's tiger power, he knew that he couldn't beat it, it should be said that Brother Biao's limbs are developed, and if his mind is more flattering, maybe he can get a few hundred more cars of night pearls......

……

Everyone watched the two guys fighting for ore without knowing whether they were alive or dead when their lives were not guaranteed, and they couldn't help but feel embarrassed.

"Gone!"

Wang Feng picked up the unconscious Maimaiti on his back and strode forward.

Everyone also followed closely, this underground karst cave is huge, below the cave is a river channel, it may be that the water flow is not as big as before, the river gradually becomes smaller, and in the middle of the river is washed out of a river channel with a width of about 20 meters, both sides of the river channel expose two flat planes with a width of more than 20 meters, just like a deliberate road, let everyone rest assured that although the road is smooth, it is not slippery, it is estimated that it is the cause of ore, and there is no growth of plants such as moss......

Along the way, everyone made an exclamatory sound from time to time, this karst cave because the limestone layer of each part contains different amounts of limestone, the degree of erosion is different, it is gradually dissolved and divided into a cave that is not dependent on each other, a thousand postures, steep and beautiful peaks and strange landscapes, what is even more amazing is that these reluctant scenery is mixed with some luminous ore, which is more and more intoxicating.

Especially the girl, she let out a cry of surprise all the way, everyone didn't know anything about geology, so naturally they didn't know what the girl had discovered, but everyone knew that this road was very, very slow......

Time passed slowly, and slowly, the joy of being shocked by the spectacle vanished, replaced by anxiety and inexplicable irritability.

It was Liu Biao and Zhang Yun, who had been arguing about the ownership of this cave, that were quiet.

It seems that this cave will never end, and there will always be a hazy light in front of it, and when you shine it with a lighter, it will immediately be brilliantly lit, and at this time, you will lose interest in the beautiful scenery of a thousand forms.

An hour!

Two hours!

Five hours!

……

It has been a full seven hours, the cave still has not the slightest sign of reaching the end, but the river below the river is becoming more and more fierce and agitated, encountering a large arc, the water splashes on both sides of the bank, to everyone's relief, there is always a wide road on both sides of the river, if it is the cold and biting water for seven hours, it is estimated that no one can support it.

The girl lost the interest she had at first, and began to become silent, except to encounter different rocks, and occasionally stop to observe with a magnifying glass.

However, Zhang Yang still admired this girl's perseverance very much, and she walked for seven hours without the slightest fatigue.

Zhang Yang didn't know that for a geologist, living in the barren mountains and mountains for a long time has trained a good pair of foot strength, although Xuelian is still just a student, she usually goes to the field for internships, and her endurance and willpower are much stronger than her soft appearance.

The atmosphere inside the cave became oppressive, except for the sound of water flowing in the river, only the breath of everyone could be heard.

"Stop! Stop! Stop! Liu Biao let go of his hand and threw Zhang Yun to the ground.

"Brother Biao, you don't have to throw me like this if you have an opinion about me, I'm a wounded, do you know what a wounded is? The wounded are the injured and need to be taken care of......" Zhang Yun's eyes were fast, and the moment Liu Biao let go, he stood on the ground with an uninjured foot, jumped to the wall and stood.

"Damn, I've been carrying you for seven hours, people are iron, rice is steel, you have to eat something!" Liu Biao scolded and scolded.

……

Liu Biao said this, everyone couldn't help but look at each other for a while, in fact, everyone's stomach was hungry, but, intentionally or unintentionally, they were ignoring this problem, and now, this most fundamental problem was raised by Liu Biao.

"I still have some food here." Aze unfastened his backpack.

When everyone heard this, they were immediately overjoyed, even Snow Lotus couldn't care about being shy, and squeezed to Aze's side.

However, when everyone saw the food in Aze's backpack, they were all disappointed, where is the food, all of them are some snacks, including beef jerky, spicy radish, dried shredded squid, although there are also a few bags of non-staple food, but looking at the biscuits that are not much bigger than their fingers, everyone feels even more hungry......

"That's the food you brought?" Zhang Yang looked at Aze and Liu Biao with a depressed face, remembering that the jeep they rented had a lot of food on it.

"That...... Ahem...... This is my ......" Liu Biao looked embarrassed, when he went up the mountain to pay tribute to Aze and his brother, he especially cleaned up some things in his backpack and brought a lot of snacks.
