Surprises came and went faster, Su Jin quickly scratched his scalp and set up camp on a high place, Su Jin wandered around the sand pit and thought about it so that his eyes straightened.

Although his second uncle, who worked in a petroleum refinery, once took him to take a group photo in front of the tall distillation and fractionation tower, Su Jin thought that it was the most stupid background he had ever photographed, and he was not interested in those tall iron vessels and winding pipes at all.

And when he really wanted to do these things at this moment, Su Jin was completely blind; That night, Su Jin drew one sketch after another under the candlelight, trying to recall the poor little memories of later generations, but Su Jin quickly denied each picture designed; Because although there are some eyebrows, these devices have not been able to be made in this year.

Li Ahri was very excited, she was chattering blindly on the side, one time she would take a towel to wipe Su Jin's sweat, and then she would come to Su Jin's ear and sigh, so that Su Jin could not be quiet, Su Jin was annoyed, and threw down the drawings and the device full of brains to push Li Ahri down on the blanket and bombarded it, poor Li Ahri was made to death, and finally fell asleep tiredly.

Su Jin, who was lying on the side, still couldn't sleep, I don't know how long it took, he suddenly jumped up, scolded himself for being stupid, he was always imprisoned by the thoughts of later generations, and delusionally wanted to fractionate different ingredients such as gasoline and diesel, but what was the use of dividing it in this year? Needless to say, the result is the word 'burn', in which case there is no need for any complicated device, only the oil needs to be divided into two parts, one is a combustible mixture, and the other is the residual dregs.

In this way, it is much simpler, use a thick iron sheet to make a sealed still, the top connecting pipe is cooled through the pool, and finally the outlet drips out of the mixture of cooled diesel gasoline and other oils, this device is very simple, with the current level of technology is definitely not a problem.

Su Jin hurriedly drew the figure on the paper, and then fell asleep satisfied.

Early the next morning, Su Jin summoned more than a dozen craftsmen who brought with him, and ordered them to make a small experimental device according to their own design.

Su Jin couldn't wait, and couldn't wait for the next day, so he collected half a barrel of oil and poured it into it that night, and after checking its tightness, he began to burn it violently with firewood.

All the people gathered at the exit of the cooled iron pipe, looking at whether there was fire oil evaporated as Su Jin said, their eyes were sour, and they didn't see half a drop falling.

Di Qing looked at Su Jin with some pity, it seems that Master Su is not omnipotent, this thing is weird, it is obviously oil, how can it turn into water vapor and run out, Lord Su was a little whimsical, and was about to comfort Su Jin for a few words, when he suddenly heard Ma Han's ear drums exploding: "There is, look, it is dripping out." ”

Wang Chao held the torch and leaned forward, Su Jin pulled him away and reprimanded: "That's fire oil, sticky fire ignites instantly, don't be careless." ”

Everyone took a closer look, only to see that there were clear and yellowish transparent oil dripping out of the exit, at first one drop or two, and then faster and faster, and finally most of the oil in half a barrel actually dripped half a teacup of fire oil, Su Jin distilled the oil dipped in a strip of cloth and lit the fire, but saw that the flame was bright and dazzling, and the sound of peeling was loud, but there was very little black smoke.

Everyone cheered and thundered, it was really feasible, and it was really possible to refine the pure fire oil, but when everyone used the fire oil on weekdays, they didn't feel it, they only knew that they were on fire and threw it around, and this time they personally participated in the refining, and they were happy.

"Congratulations to Lord Su, congratulations to Lord Su, it's really a wonderful idea, in this way, this is a treasure." Di Qing laughed and congratulated again and again.

Su Jin was stunned with a bitter face, and everyone looked with his eyes, only to see that a large pile of firewood had disappeared, so he refined this small cup of fire oil, and actually consumed a lot of firewood, which was too uneconomical; If you want to refine more fire oil, it is useless to cut down all the trees all over the mountains and burn them for firewood.

Moreover, Su Jin also understood why there was no fire oil dripping out at the beginning, in fact, the temperature was not enough, the temperature of the firewood was not powerful enough, and if you want to steam more fire oil, you must solve the problem of combustibles, first, to save money, and second, to be powerful enough; But where to find such fuel?

Thinking that he couldn't use the oil sent for nothing, Su Jin was in pain, could he really only burn the smoke to make ink? That's a tyrannical thing.

Su Jin sat on a stone in a daze, and everyone's excitement passed, understanding that although this method was feasible, the gains outweighed the losses, a small cup of hot oil required a large amount of firewood, this was obviously not a cost-effective thing, and Lord Su's whimsy this time was afraid that he was going to touch the south wall.

The footsteps rustled closer, and someone whispered: "Master Su, the villain has something I want to talk to the adults." ”

Su Jin looked up and saw that it was Dan Muji who was wrapped in a cloth towel, so he sighed and said, "Anyway, do you want to go back?" If you have found the oil, your duty has been completed, and if you want to go back, you can leave, and tomorrow I will have someone bring you some dry food. ”

Dan Muji waved his hand and said: "No, the villain saw that the adults were worried that the firewood was not enough to burn, so he remembered one thing, and he didn't know if it could be useful, so he wanted to tell the adults." ”

Su Jin patted the stone beside him and said, "Sit down and say." ”

Danmuji sat down sideways and said, "Have you ever seen a stone that can be burned?" ”

Su Jin was stunned and said, "A stone that can be burned?" ”

Danmuji nodded and said, "Yes, it's black, and it can burn." ”

Su Jin was startled, grabbed his arm and said, "You mean, there is one in this mountain?" ”

Danmuji pointed to the north and said: "A few years ago, I chased a wild boar over a few mountains, and saw a lot of black stones under a valley cliff in the north, I didn't care about it at the time, but then I lit a bonfire to roast meat at night after catching a wild boar, and suddenly found that the black stones under the bonfire were burning brightly, and the roasters couldn't stand it; At that time, I thought I was dazzled and hurriedly extinguished the fire, but I was not mistaken, the whole ground was burning, and I was so frightened that I ran away overnight; When I got home, my parents said that I might have hit an evil spirit, and then I forgot about it. ”

Su Jin exclaimed: "That's coal, and the black stone is coal." ”

Danmuji looked dazed and asked, "What is coal?" ”

Su Jin took a breath and said: "Coal, the people of the capital use it for heating in winter, there are more than a dozen mines of this kind of coal in various parts of the Great Song Dynasty, is there actually one here?" ”

Dan Muji still doesn't understand what Su Jin is talking about, Su Jin understands, these mountain people have lived in the mountains all their lives, almost isolated from the world, naturally don't know what coal is, as far as Su Jin knows, coal has been mined in large quantities in the Great Song Dynasty, Jiangxi, Henan and other places have set up more than a dozen mining areas, the three divisions of the yamen have an independent department called the Iron Metallurgy Division specializing in mining and smelting, Su Jin just now did not think of using coal as fuel, but the price is expensive, and the road is far away, and the gains outweigh the losses. But I didn't expect that the barren mountains and mountains in the land of Yindong actually had not only oil, but also coal; This can be regarded as a treasure land in the land of fast treasures.

If, as Danmuji said, this was an unexpected surprise, then the mining of coal and the refining of oil would not be delayed, and God favored her, and Lady Luck kissed her forehead again.

Su Jin couldn't wait, he wanted to call someone to check it out immediately, but the late-night mountain trip was really a bit nonsense, so he had to stay up patiently until dawn, and the sky was bright, Su Jin shouted at everyone and shouted, filled his stomach indiscriminately and set off with dew.

A few years have passed, and Danmuji's memory is also a little vague, with the little memory that remains, Danmuji finally took Su Jin Diqing and others to the bottom of the cliff where there is no grass.

On the way, Su Jin was still worried, later generations heard reports that the coal mine can be smoldered underground for hundreds of years, that day Danmuji ignited the underground coal, and exposed to the air, I don't know if it has been burned beyond recognition, but when Su Jin faced a large piece of black stone, only to find that his worries were really redundant, maybe it was the heavy rain that extinguished the charcoal fire, there was no trace of fire in front of him, the black stones full of eyes were inlaid in the lower part of the cliff, although there was only one zhang Xu Kuan, but obviously this is the coal mine.

Su Jin didn't know how the coal mine could be exposed, the cliffs on both sides were like axes and knives, as if they had broken apart after an earthquake, exposing the coal underground.

Su Jin had no time to investigate the reason, and ordered someone to chisel down a few pieces of charcoal and burn them on the firewood for a while, only to see that the charcoal was burned red, and he moved it aside, and a small piece of charcoal actually burned for a full hour before it was extinguished, Su Jin looked up to the sky and laughed, this 10,000 horses was really worth it, and he not only wanted to become an oil tycoon, but also became a coal boss who was spurned but envied by thousands of people in later generations.

(PS: I'm not talking nonsense, it is recorded in Mengxi's written conversation: There is oil in the territory of Yan and Yan, and it is said that Gaonu County produces fat water, which is also.) Born in the water, the sand and gravel are mixed with the spring water, "melancholy" and come out, the native people take the pheasant tail to carry it, it is collected into the reed, quite like pure lacquer, burn like hemp, but the smoke is very thick, and the curtain is black. If you suspect that its smoke can be used, try to sweep its coal as ink, black light is like paint, and pine ink is not as good, so it is great. Those who know the text as "Yanchuan Stone Liquid" are also. This thing will be great in the world, and it will be done from the beginning.

Cover oil at most, and be born in the earth endlessly, not as pine as sometimes exhausted. Today, Qi and Lu pine forests are exhausted, and gradually to Taihang, Jingxi, and Jiangnan, and most of Songshan are children. The coal maker covers the benefits of unknown stone smoke.

The charcoal smoke is also big, and the ink is clothed. Yu drama for "Yanzhou" poem "Erlang Mountain snows a lot, and Xuanzhuo Qionglu learns to stop people." The plain clothes are not old in winter, and the stone smoke is like Luoyang dust. ”

Another: The land of Yindong produces coal, which was not mined in the Song Dynasty, but now it has been mined on a large scale, although the location is slightly different, but it is all in the territory of Yanyan Road, and the protagonist is shrouded in the halo, which is naturally full of benefits; The novelist said that if you want to study the party deeply, you can check the information and compare it yourself. ）
