Lu Bu invited Guo Tu and Cui Yan to take a walk below the mine, and of course they had to go to the place where the craftsmen underground bathed to change their clothes.

When he arrived at the coal minemaker's bathhouse, Guo Tuzan said: "Bathing in this place must be much happier than in a wooden barrel." ”

"Happy or not, Guo Gong will realize it later." Changing his clothes, Lu Bu smiled at him.

The clothes worn by the miners on the mine were short clothes with short hems.

In the eyes of Guo Tu and Cui Yan, who are used to wearing long clothes, this kind of clothes are indeed very strange when worn on their bodies.

After changing into clothes, Cui Yan asked Lu Bu, "Dare to ask Chu Hou, why is this kind of clothing so short?" ”

"It's short." Lu Bu replied: "A short outfit like this makes it easier to do things." If you go down the mine in a long coat and make a mistake with the hem and sleeves of your clothes, how can you still work? ”

Lu Bu's answer made Guo Tu and Cui Yan think so, and both of them didn't ask more.

Following Lu Bu to the entrance of the mine, Guo Tu and Cui Yan saw a miner shaking a huge fan vigorously.

Since there was no electricity, the fan had to be shaken by hand.

Different from other things, there are a total of six miners who shake the fan, and every moment will be shaken by another person, otherwise just one person will shake it for a long time, not only can not ensure the normal operation of the fan, but the arm of the person who shakes the fan will be so weak that it will be broken.

Seeing the fan, Guo Tu asked Lu Bu again: "General Lu, what is this?" ”

"Mine ventilation." Lu Bu replied: "There is no breath below, and people will be suffocated to death inside, how can they send coal?" With this kind of thing, we can dig the coal out of the ground. Yuan Gong wanted to use it to forge steel, and without this, it would be impossible to send even a piece to the ground. ”

thought that if they found a coal mine, they would make a lot of money, but Guo Tu and Cui Yan didn't expect that mining coal would be so troublesome.

The two glanced at each other and followed Lu Bu down the mine.

Walking into the mine, the scene in front of them gradually darkened.

Guo Tu was about to ask questions, and the steward who followed behind had people light torches.

"You still need a torch to get into the mine." Guo Tu was even more stunned.

Lifting the torch, Lu Bu was also irritable in his heart.

Open flame lighting has not been solved, if it continues like this, sooner or later there will be a big accident in the coal mine.

Although he handed over the matter to Liu Hong, Lu Bu didn't expect him to actually create electricity and use it to generate electricity to light the way under the mine.

The lighting problem in the mine has to be solved.

"I don't understand." Following Lu Bu down to the mine, Cui Yan said: "Since the coal mine is underground, dig the ground directly, why do you want to open a path underneath?" It's no wonder that transporting coal from the ground like this is slow. ”

"Coal is hundreds of steps underground." Lu Bu said: "Dig from above, how deep do you have to dig?" By then, the coal mined will not be worth as many hours as it is spent. ”

"That's what General Lu said." Guo Tu, who was following him, said: "It's still General Lu who can see through it. ”

Along the way, they passed several places with fans, and Lu Bu explained them one by one.

The two of them understood the reason for doing this, and they didn't feel anything other than trouble.

Once they went down the mine, they felt that it was not easy to mine the coal, and they also felt that the pile of coal on it did not seem to be much, and it was possible that it was indeed the craftsmen here who had spent a lot of time to accumulate it.

As he was walking, he was confronted by a miner with a basket on his back.

The miner bowed and walked step by step towards the entrance of the mine.

Watching the miners walk over, Cui Yan asked, "Only someone can carry such a little coal out every time?" ”

"It's all about manpower, and there's not much in this basket." Lu Bu sighed and said, "I also want to transport more at a time, but it's a pity that there are only so many people who can go halfway." I can't force craftsmen to send coal out day and night. Let's not talk about human life as important, let's just say that if the craftsmen are tired and lie down, who will come to work in the coal mine in the future? No matter how much coal there is, you can only watch it lie in the ground. ”

"What Chu Hou said is reasonable, but we don't understand the reason." Guo Tu and Cui Yan both responded.

Entering the mine, they saw a lot of shelves supported by wood, and when they got to the depths of the mine, the shelves turned to steel.

Guo Tu walked to one of the shelves, touched the wet shelf, and asked Lu Bu, "How did such a thick iron pillar come down there?" ”

Of course, Lu Bu would not tell him that this bracket is actually hollow, and it is lifted up with hydraulic pressure to achieve the purpose of support.

At the beginning, in order to figure out how to use hydraulic pressure to jack the pillar, Lu Bu took a lot of thought.

Now that the depths of the mine have been replaced with this directness, the possibility of roofing will be much smaller.

"The strength of the craftsmen of the mine is not comparable to ordinary people." Lu Bu smiled and said to Guo Tu: "If Guo Gong wants to give it a try, I'll ask someone to come over when I go back." ”

"Forget it." Looking up at the bracket that supported the top plate, Guo Tu said: "I can't bear to carry such a thick iron rod for him." If you want to talk about why coal is so expensive, this time I completely understand. Chu Hou has invested so many things in the coal mine, how much is it worth just these iron rods? ”

"Guo Gong can see it." Lu Bu replied: "Materials, labor, and coal storage in the open field are all troublesome. In fact, I also calculated a few days ago that since mining coal mines, I have not made much profit, but have lost a lot. ”

"Since it's a loss, why does Chu Hou still have to do it?" Cui Yan asked in disbelief.

"30,000 sets of armor are worth a lot." Lu Bu didn't answer directly, but asked Cui Yan rhetorically: "Why is Yuan Gong willing to exchange so much armor for coal with me?" ”

Cui Yan was asked by Lu Bu in a word, and he didn't know what to say.

The cost of armor is indeed not low, from the selection of cowhide to forging the armor, and then to inlaying the armor on the cowhide, each set of armor consumes a lot of man-hours, manpower and materials.

30,000 sets of sophisticated armor, even for the Yuan family in Hebei, is a lot of money.

Yuan Shao was willing to exchange so much armor for coal with Lu Bu, which shows how important coal is in today's world!

"Coal is important, so important that if we want good ordnance and armor, we have to use it." Lu Bu said: "I have invested a lot in mining coal, but even if I lose money, I must continue to operate the coal mine." Not for anything else, just for this piece of black stone, which can help me create better weapons, and also allow my soldiers to have better armor and better armor from now on. ”

He continued: "Soldiers kill the enemy on the battlefield, and shoddy ordnance only gives them their lives on the battlefield. Although I cannot guarantee that every soldier will come out alive and come back alive, I can do my best to provide them with the best of whatsoever. ”

Lu Bu can have such an opinion, which is indeed beyond the expectations of Guo Tu and Cui Yan.

The two of them knew Lu Bu in the past, because this person was greedy for small profits, and he was often able to sell the people around him for a little benefit.

But the Lu Bu in front of them was completely different from the one in their impression.

For the sake of the soldiers of the three armies, he would rather lose money than continue to operate coal.

A temperament like this is not at all the Lu Bu that the two of them understand.

They looked at each other in astonishment, Guo Tu and Cui Yan didn't say anything.

Lu Bu said to them: "Don't just talk to me here, there are still a lot of things worth seeing in the depths of the coal mine, I will take you to the working face to have a look." ”

Walking along the alleyway, Guo Tu and the others found that the air was gradually getting dirty and dirty, and the wind was no longer blowing from behind, but from the front.

"General Lu, why is the wind not quite right here?" Cui Yan, who noticed the problem, asked Lu Bu: "The wind was blowing from behind before, how did you get here, but it came from the front?" ”

"Actually, there are two ways to get to the work surface." Lu Bu replied: "One of them is called the air inlet lane, and the other is called the air outlet lane, in order to let the two of you feel the coal mine more deeply, I did not choose a relatively clean air inlet lane, but chose a dirtier air outlet lane." ”

"What's the difference?" Guo Tu asked.

"As the name suggests, the air inlet tunnel is used for air intake, and the air outlet tunnel is used to blow the dirt of the working face out of the mine." Lu Bu said: "Through the circulation of the wind, there will always be a fresh breath on the working surface, and people will not be suffocated here, let alone suffocated." ”

What Lu Bu said was easy to understand, Guo Tu and Cui Yan nodded, and Guo Tu even praised it: "I didn't expect that there are so many ways in coal mining." ”

"There are many ways." Lu Bu grinned: "Here we can still recognize each other, wait until we get up the mine, and then see if we can recognize each other." ”

Looking at Lu Bu suspiciously, Guo Tu and Cui Yan were silent.

Both of them were muttering in their hearts, the person is still the same person, there is no change at all, could it be that if you get out of here, you will become someone else?

I didn't agree with Lu Bu's statement in my heart, but neither of them would break it, after all, when they came to the bottom of the mine, many things they saw completely subverted their previous speculations about the coal mine.

Coal is black on the ground, and if it weren't for the fact that it burns and produces a lot of heat, no one would believe that it is buried so deep underground, and that it is so difficult to mine.

Lu Bu explained to the two of them all the way, and the coal mine manager who followed them always didn't say a word.

Everything that should be said was said by Lu Bu, and many of the things he knew were not even as professional as Lu Bu, and it was obviously not appropriate to interject at this time.

led Guo Tu and Cui Yan along the wind alley to the work face, and after walking for a while, Cui Yan asked, "Why is there so far?" ”

"Far?" Lu Bu seemed to be surprised and said, "How can this distance be considered far?" If you want to say far, wait until the coal mining is deeper in the future, then it is really far. ”

"The craftsman who went out with coal on his back just now set off from the front?" Cui Yan asked.

"The coal is mined from the working face, and if he doesn't start from here, where else can he start from?" Lu Bu said: "The Xuzhou coal mine has only been mined for a long time, and as the coal mine gets bigger and bigger, the distance to go will be farther and farther, and some working faces are even dozens of miles away from the mine. ”

What Lu Bu said, Cui Yan couldn't imagine it at all.

Although there is air convection under the mine, people still feel depressed when walking in the tunnel.

"Guo Gong and Cui Gong watch their feet." Walking forward, Guo Tu stumbled, Lu Bu supported him, and then reminded: "The mine is not comparable to the ground." When a person falls here, he will grin his teeth at the lightest, and at the worst he will be crippled for life. ”

I didn't believe what Lu Bu said, Guo Tu replied: "General Lu said this, isn't it a little scary?" ”

"Can Cui Gong slap the hat on Guo Gongdu?" Lu Bu asked Cui Yan.

Cui Yan looked at him suspiciously, but didn't start.

Lu Bu replied: "I don't mean anything else, I just want Guo Gong to know the difference between being underground and being on the ground." You don't need to slap too hard, just give it a gentle beat. ”

Looking at Guo Tu, Cui Yan still didn't start.

"Since General Lu said so, then ask Cui Gong to pat it." Guo Tu said to Cui Yan: "I still have to have some strength, I wear this hard thing, and it is impossible for Cui Gong to hurt me." ”

Guo Tu asked him to slap, and Cui Yan said: "Since Guo Gong wants me to slap, then I have to offend." ”

According to what Lu Bu said, Cui Yan slapped Guo Tu's hat.

He didn't exert much force, but Guo Tu felt that his head was dazed and he almost didn't stand still.

Lu Bu held him again and said to the two of them: "With Cui Gong's strength just now, if it was above the mine, I am afraid that it would not feel too much, but when it comes to the bottom of the mine, it will be very different. So when you go underground, it's better to be careful. ”

was slapped by Cui Yan, and Guo Tu, who knew that he was powerful, was really careful when he walked after that.

It was a long walk before they saw a faint flickering fire in front of them.

In the light of the fire, they heard the sound of "clanging".

Pointing to the place where the knocking sound came from in front, Lu Bu said to Guo Tu and Cui Yan: "The front is here." ”

"I've come this far." Guo Tu replied: "It's really not easy for craftsmen to work in the underground. ”

"It's such a long way to come here, and you'll have to walk the same distance when you go back." Lu Bu replied: "It's enough to choke on nothing when you come and go, not to mention that the craftsmen have to carry tools and carry coal when they go out." ”

"I thought that Chu Hou was asking for such a high price indiscriminately." Cui Yan also nodded, and said thoughtfully: "Now I went to the bottom of the mine and looked at it, only to know that there was no one at all, it was because I thought badly." ”

"Anyone who knows me knows kindness." Lu Bu smiled: "How can it be a sky-high price?" ”
