Seeing those neatly stacked boxes, Lu Bu asked the steward who followed him, "This is the place to change the clothes of the craftsmen in the mine?" ”

"Exactly." The steward replied.

"Where's the bathing place?" Lu Bu asked again.

"It's right in the back." The steward asked, "Do you want Chu Hou to take a look first?" ”

"Take me to see it." Lu Bu raised his hand.

The steward led him, Sun Ce and the others through the room where they had changed their clothes and came to a room at the back.

Entering this room, Lu Bu found that there was a huge wooden pool here.

The pool is filled with steaming water, and since the whole room is enclosed, the water in the wooden pool is easier to keep warm for a long time.

"Don't you think it's boring here?" Entering this room, Lu Bu frowned slightly and asked the steward.

"It's really stuffy." The steward replied, "So there are ventilation windows around the room, and I will only have the vents opened when the craftsmen come up from the well." ”

"Got a vent?" The steward said that there was a vent, of course Lu Bu wanted to take a look: "Open it and I'll take a look." ”

The steward instructed the men who followed, "Open the window quickly." ”

Several people stepped forward one after another, walked around the house, and opened more than a dozen windows.

When he entered this room, because the room was filled with heat, and the vents were in the same color as the walls, Lu Bu didn't notice it.

When the window was opened and a cool breeze poured in, he nodded with satisfaction: "Who thought of all this?" ”

"It's all Chen Gong." The steward replied: "Only Chen Gong has such wisdom, how can a stupid person like us come up with these ideas." ”

The steward said that Chen Gong came up with the idea, so Lu Bu didn't ask any more.

At the beginning, he led a large army south to crusade against Sun Ce, and Chen Gong stayed behind in Pengcheng.

Coal mines are the most important source of finance in Xuzhou, and it is certainly impossible for him not to attach importance to them.

The ventilation of the ground and the entry and lifting of the mine craftsmen did not see any problems, and Lu Bu ordered everyone to go outside with him to change their clothes and prepare to go down the mine.

Back in the outer room, Lu Bu changed his clothes with the others.

Not only himself, but even Sun Ce and the guards who followed him here were all tall and tall.

Most of the miners in the mines were relatively unsuitable for war.

Except for a few people who are older and no longer suitable for serving in the army, most of the others are relatively short.

Lu Bu and the others were wearing the biggest clothes, but they were still tied very tightly, and there was a feeling that as long as they used a little force, they would stretch their clothes.

After changing his clothes, Sun Ce looked at Lu Bu: "I'm still not comfortable wearing this clothes, doesn't Chu Hou feel tied?" ”

Sun Ce was shorter than Lu Bu, and his physique was not as burly as him.

Even he felt that his clothes were very tied, and Lu Bu was of course even more uncomfortable wearing them.

Trying to stretch his arm, Lu Bu took off his shirt: "It's really better not to wear this clothes." ”

"It's damp and dirty down there." The steward hurriedly said: "Chu Hou is still wearing a piece of clothing, and it is better to wash it when he comes up." ”

"After the craftsmen came up, how did they clean it?" Thinking of something, Lu Bu asked if he wanted to take care of things.

"It's all washed in the pool just now." The steward obviously didn't understand what Lu Bu was asking, and replied with a blank face.

"I'm asking what they use to get rid of the soot?" Seeing that the steward didn't understand what he meant, Lu Bu simply explained the problem more clearly.

The steward suddenly realized, and hurriedly said to Lu Bu: "Back to Wenhou, after the craftsmen came up, they all used green salt to rub off the coal ash on their bodies. ”

"Green salt." Lu Bu frowned.

Before he invented toothpaste, people in this era hardly knew how to brush their teeth, and only a few nobles would use green salt to clean their teeth.

Since the invention of toothpaste, it was first chosen by women from noble and noble families.

With the development of the local economy, people can also afford toothpaste, so it is gradually popularized.

In addition to toothpaste, Lu Bu also invented mosquito repellent water and so on, but he didn't expect to invent soap.

If he hadn't come to the mines, he might have had a hard time thinking about soap when he thought that the craftsmen in the mines needed relatively mild cleaning supplies when they came down the mine.

Before coming to this era, Lu Bu had seen how soap was made.

The materials used to make soap are also easy to find in this day and age.

With this thought, he had already thought of making soap when he returned to Pengcheng.

It's just that now it's more important for him to go down the mine and take a look at the environment.

The deep clothes worn by people in the late Eastern Han Dynasty, although they have trouser legs, the two trouser legs are separated, and the pants of later generations are not the same concept.

The deep coat grows and covers the trouser legs, and others look like they are wearing the whole outfit, but in fact, part of it is a vacuum.

Lu Bu had long thought about changing the style of this kind of clothes, but he didn't have the time.

Coming to this era, he has found that many things need to change.

It's just that with his own strength, it is difficult to turn things around and bring many things to this era that will not appear until later generations.

The clothes were too small to wear on his body at all, so Lu Bu could only wear it bare-chested and tie it around his waist.

greeted Sun Ce and the others, and under the guidance of the steward, they walked towards the wellhead.

Two thousand years later, in coal mines, there were few inclined shafts at the entrance to the wellhead, and most of them were vertical shafts that went straight up and down.

The shaft has a large tank like an elevator that can lift or drop dozens of miners at a time.

There are many conditions for the construction of vertical shafts, the most important of which is a high degree of mechanization.

Of course, there could not have been a high degree of mechanization in the late Eastern Han Dynasty, and it was impossible for Lu Bu to drill a more convenient vertical shaft in this era.

The craftsmen of the mine enter and exit the mine through inclined shafts.

The coal mined from it is also carried basket by basket by manpower.

When they went down the mine, Lu Bu and others staggered past many craftsmen carrying coal on their backs.

The craftsmen had a wind lamp hanging from their chests, but the opening of the wind lamp was small to prevent the flames from coming into direct contact with the air below the mine.

Since the establishment of the Xuzhou Coal Mine, there has not been any major casualty accidents, and even if there are occasional casualties, they are caused by factors such as roof and landslides.

Before going down the well, the steward ordered someone to bring the wind lantern, and Lu Bu realized that something was not quite right.

No matter how small the opening is, it is still a wind lamp after all.

It is impossible to block the contact between the flames and the air in the mine because of its small opening.

Unlike many mines, coal mines are accompanied by the production of a gas called gas.

If the gas concentration exceeds 5%, it will explode when it encounters an open flame.

So far, there has been no explosion in the Xuzhou coal mine, one is lucky, and the other is that the mine is not too deep, and it is relatively difficult for gas to gather.

It was very clear that if the problem of going into the well with an open flame was not solved, a serious safety accident would occur sooner or later, and Lu Bu's face turned cold.

But he didn't blame the steward.

At first, he only temporarily chose to use fireflies as the light source for the well.

The light of the fireflies is very faint, and it can't illuminate much of the area at all.

And its most fatal weakness is that in autumn, the fireflies will disappear completely, and it is not a long-term plan to expect to capture them as a lighting tool.

************************************

Although his face was not very good-looking, Lu Bu did not blame the steward, and led everyone all the way to the bottom of the mine.

When they entered the mine, there was a hair dryer behind them to send in fresh air, and Lu Bu and the others could still feel a trace of coolness, which was not very uncomfortable.

The deeper you go into the mine, the less cool breeze comes in from the mouth of the mine, and not only do you feel hot and dry, but you also feel a little suffocated when you breathe.

"The wind from the wellhead doesn't seem to be able to reach this place." Lu Bu stopped and looked around by the light of the wind lamp: "If there is no ventilation for too long, it is likely that none of the craftsmen under the mine will be able to go up." ”

"The wind really can't reach." The steward replied: "But when the wind blows in at the mouth of the well, the craftsmen can still breathe inside." ”

"That's because the mine isn't deep enough." Lu Bu said: "What we are mining now is actually the most superficial layer of coal. The most superficial layer of coal, with a large ash content and a low combustion value. Really good coal is in the bottom eight to thirteen tanks. When the mine reaches that depth, it is impossible to bring fresh breath to the well with the blowing air at the wellhead. At that time, not only will the craftsmen have to suffocate underneath and go down the well with an open flame, but it will also be easy to cause a gas explosion. ”

Although he has been in charge of the mine for a long time, many things have not yet been managed.

In particular, the gas explosion that Lu Bu said was a completely unfamiliar existence to him.

But he also knew that Lu Bu was right, as the mine got deeper and deeper, the fresh air poured in from the wellhead would become more and more unable to reach the working face.

If there is not enough air, not to mention that the craftsmen will not be able to mine coal, it is not certain that they will not even be able to survive underground.

The further down he went, the bigger the problem Lu Bu saw.

Wooden beams are still used for the support of the mine.

There is no problem with using wooden beams in shallow wells, but if wooden beams are used in deep wells, the wood cannot withstand the pressure at all.

Once the support column is broken, it will rise or collapse in patches.

When the time comes, as many craftsmen are in it, they will be buried.

"It's okay on the ground, but it's not like that underground." Accompanied by the steward, Lu Bu and the others saw that they were about to walk to the coal mining face, and when they heard the clanging sound, he said to the steward: "You have not experienced a major accident in the coal mine. You know, coal mines can bring us money, but it is also a tiger that devours human life. If you're not careful, it will eat people, and it will eat many people at once. ”

Lu Bu said this, and nodded incessantly.

In fact, something really happened to the Xuzhou mine, and people died.

It's just that not many people died in the past, and he and the other stewards only made some rectifications for the accidents that had occurred, and they didn't improve much.

The steward didn't know that Lu Bu didn't mean to blame him when he said this.

With the current means, it is simply impossible to mine deeper coal mines.

Seeing that the steward's face was very embarrassed, Lu Bu patted his arm lightly: "I can't blame you for these things, I didn't get them done." When I'm done, if you don't do well, I'll kill someone. ”

Hearing that Lu Bu didn't mean to blame, the steward breathed a sigh of relief.

But at the same time, he was worried, after all, Lu Bu said that one day in the future, he would prepare all the facilities related to the coal mine, and if there were any more casualties, he would arrest someone from the steward and kill him.

Managing the coal mine, although the income is high, the whole family can live a very prosperous life.

However, Xiang Shang's head may not be there at any time, and the steward subconsciously wanted to touch his neck, but in front of Lu Bu, he didn't dare.

Although everyone was carrying wind lanterns, it was still very dark in the alleyway.

Lu Bu glanced at the steward again and beckoned everyone to walk towards the work surface.

When mining coal at the beginning, Lu Bu adopted the mining method of later generations.

First, open the channel from both sides, one of the channels is the air outlet and the other channel is the air inlet.

The mined coal is sent out of the mine through the air intake.

He had a good design, thinking that as long as the air was in place, the air inlet would always be cool, while the air outlet would be relatively dirty and stuffy.

When he arrived at the bottom of the mine, Lu Bu realized that what he had thought before was indeed too naïve.

The wind poured into the mine from the ground is simply not possible to reach the working face.

The only effect of the wind sent in by the wind bag is to bring some fresh air to the well, and to keep the working face still barely breathing.

When Lu Bu arrived, the craftsmen stopped what they were doing.

Walking towards the craftsmen, Lu Bu asked, "When you go down to the mine, how do you eat and drink?" ”

"Someone sent the water." One of the craftsmen replied: "We will bring some ourselves, it is too hot here, and we are already sweating before we can work, and we have to drink a lot of water every day." ”

"Where's eating?" Lu Bu asked, "Do you go up to eat, or is it just below?" ”

"Chu Hou may not know that what he eats is particularly fragrant when he brings it down." The craftsman replied, "I didn't feel like I had eaten anything on it, but when I got here, it seemed completely different." ”

Before coming to this era, Lu Bu had really heard that eating under the mine was indeed more fragrant than on the ground.

Although the craftsman did not say it directly, he already understood that these people liked to bring what they ate to the well.

"It's too hot in here, if you can't stand it, don't hold on." Lu Bu instructed the craftsmen: "Although the food in the well is fragrant, it is very hot here. People are always doing things in the heat, and they are absolutely unbearable. ”

"Thank you Chuhou for your concern!" The craftsmen agreed.

Lu Bu nodded, and his eyes fell on the support of the working face again.

The work surface here is, of course, not as complicated as the work surface of later generations.

At least on the side walls of the work face, there is no facility dedicated to pumping out gas.

Looking back at the sealed side of the back, Lu Bu asked the steward: "After the goaf, how did you fill it?" ”

"Most of them are filled with yellow mud." The steward replied: "How much coal is sent, how much yellow mud has to be sent down from above, and the craftsmen are indeed very hard." ”

"You're right, but none of this is unsolvable." Lu Bu nodded: "Let's go up first, I have already written down everything that needs to be rectified here, but it takes a lot of work to rectify, when you mine coal, try to only mine shallow." ”

Lu Bu proposed to go to the mine first, and the steward hurriedly replied: "I have written down everything that Chu Hou said, and I will instruct the craftsmen to look at it and try to only mine shallow coal." ”

When he left the work surface, Lu Bu looked around as he walked.

The more he looked, the more he found that this coal mine was still much worse than the real one.

First, he had to solve the problem of lighting under the mine.

If the craftsmen are allowed to work under the mine with wind lanterns, sooner or later something will go wrong.

Secondly, he also had to solve the ventilation and gas extraction processes, although Chen Gong set up two wind bags at the wellhead, but with the wind conveyed by the wind bags, it was impossible to solve the problem of underground air supply. Moreover, the gas accumulates under the mine, and if it is not pumped out, the concentration will only get higher and higher. It's only a matter of time before something happens.

Of course, the filling of the goaf is also a big problem for Lu Bu.

In later generations, the goaf was injected with mud at high pressure on the ground to achieve the purpose of filling.

If the goaf is not filled, the ground collapse is still a trivial matter, in case it causes a chain reaction and causes the underground to collapse, it is a big deal......

*************************************

Back on the ground, in the sun, Lu Bu saw that Sun Ce and the others had dark faces and bodies.

Everyone looked very embarrassed.

He laughed, pointed at Sun Ce and said, "Bo Fu, do you know how dark it will be?" ”

With a face full of soot, Sun Ce's appearance was no longer distinguishable.

He also smiled very embarrassedly, and said to Lu Bu: "Actually, Chu Hou is not much better than us, but he just went down for a trip, but he didn't expect to be like this when he came up." ”

Everyone's faces were dark, and of course Lu Bu knew that he wouldn't be much better.

He asked the steward, "Are there any bronze mirrors here?" ”

"Yes." The steward hurriedly replied: "There is a bathing place, so that the craftsmen can see whether it is cleaned." ”

"Take us there." Lu Bu waved his hand: "Let General Sun and them see what they have become." ”

The steward agreed, and led Lu Bu and the others to the room where they changed clothes.

When everyone took off their dirty clothes, he led Lu Bu and others to a cage.

When I opened the cage, there were more than a dozen bronze mirrors inside.

Of course, the bronze mirror here is relatively rough polished, and it is not as delicate as the bronze mirror in the official eunuch family or the scholar's house.

Picking up a bronze mirror, the steward held it in both hands and handed it to Lu Bu.

took the bronze mirror and looked at it, and Lu Bu found that the face that appeared in the mirror was actually black and white.

Below the mine, he could discern everyone.

When he got to the ground, he saw people more clearly, and it was a little difficult for him to distinguish them.

Seeing himself in the bronze mirror, Lu Bu shook his head with a smile: "We just went down and walked once, and it was dirty like this." The craftsmen were under the mine all day, and they were afraid that not only did their faces be dirty, but even their breath was soot. ”

Everyone looked at each other, and none of them knew what Lu Bu meant.

Even the steward, who has been taking care of the coal mine all year round, didn't understand the deep meaning of his words for a while.

"People's internal organs can't stand the dirt outside." Seeing that they didn't understand too much, Lu Bu continued: "The craftsmen are doing things below, and there is too much coal dust, and they have all sucked it into their stomachs, is there a good thing?" I don't think it's just what we see that needs to be rectified, and there are many things that we don't see waiting to be rectified. What I want is a coal mine that not only makes money, but also treats every artisan here as if it were his own family, rather than a coal mine that cares about the lives of craftsmen for money. ”

"I have written down everything that Chu Hou explained." The steward quickly agreed.

Lu Bu said in his heart, many things can't be done with just heart, and you have to figure out new technologies to solve them, with the stewards here, if you can also deal with everything, why do you need him to think about this?

Although he thought so in his heart, he did not say anything, and instructed the steward: "You are all waiting here, and Bo Fu and I will go to wash first and feel the bath here." ”

Everyone who went down the mine with him responded, and Lu Bu, who was already naked, took Sun Ce into the bathing room.

Unlike other places, there were so many craftsmen who needed to bathe here that it was impossible to prepare many barrels for them to bathe.

In the bathing room, there is only a pool made of wood.

Getting out of the pool, Lu Bu sat in the pool, seemed to take a deep breath and exhaled: "Whether it's cold or tired, as long as there is such a pool of water, soaking in it will really make people feel refreshed." ”

"Chu Hou hasn't been to the hot springs?" Sun Ce asked Lu Bu when he went into the water.

"Of course I did." Lu Bu replied: "But how can there be so many hot springs in the world, I can't go all the way to find a hot spring just to take a dip?" ”

"That's right." Sun Ce sat down in the pool, stroked the water on his body, and said to Lu Bu: "Actually, when Wen Hou goes back, he can also let people build such a pool." Although it uses more water, it is much more refreshing to soak than a wooden barrel. ”

"We feel refreshed, and the craftsmen of the mine don't necessarily think so." Lu Bu said: "It's not difficult to build such a pool, the question is how many times can I use it after I build it?" And wouldn't it be a pity to leave a whole pool of water there cold? ”

"With such a pool, is it possible for Chu Hou to wash it himself?" Sun Ce said: "When it is built, it is not impossible for the ladies to use it. ”

"That's right." Lu Bu spread his arms and stood on the edge of the pool: "When the current crisis is solved, I will ask people to build a pool in the back house." If it is built now, in case we can't hold Xuzhou, won't it be built for Cao Mengde and Yuan Benchu? ”

Turning his head to look at Sun Ce, he grinned: "What's worse is that I built it, not only will they not be grateful to Dade, but they will also tell the world how poor and extravagant I am." In the case of danger in Xuzhou, people also built pools to provide for their own enjoyment. ”

Sun Ce smiled.

What Lu Bu said was indeed right, if they failed to hold Xuzhou, when Cao Cao and Yuan Shao captured Pengcheng and saw the pools built, they would definitely say that he was poor and luxurious, and actually built such a large pool at home for bathing.

"Doesn't the Marquis of Chu have any confidence in holding Xuzhou?" Sun Ce asked Lu Bu.

Lu Bu pouted: "If you want to talk about faith, it's really nothing." Yuan Benchu and Cao Mengde each have countless elite soldiers under their hands. In terms of numbers, we may not be less than Cao Mengde. But in terms of numbers, we can't compare to Yuan Benchu. And Cao Mengde's elite soldiers and fierce generals are all elites who have been through the battlefield, and our soldiers ......"

Speaking of this, Lu Bu shook his head with a smile: "Except for a few newly built elites, most of our soldiers are stragglers, once the battlefield situation is unfavorable, I am afraid that they will flee immediately......"

Since following Lu Bu, Sun Ce had never seen him so unconfident in his subordinate soldiers.

Turning his head to look at him, Sun Ce asked, "If you really can't hold it, what is Chu Hou's plan?" ”

"The eunuchs and their families have all been sent to Jianye, and of course I will also go to Jianye." Lu Bu replied: "There is a natural danger of the Yangtze River in Jiangdong, as long as we hold there, we can lead the army to kill it again sooner or later." ”

After a change of words, Lu Bu continued: "Of course, if I can hold Xuzhou, I still don't want to lose this place." After all, I have been operating in Xuzhou for a long time, the people live and work in peace and contentment, and the local Kangtai is rich and strong. And there are a lot of resources here, not only Xuzhou, but also Huainan, Lujiang and other places that we have just won, there is also a lot of usable wealth. ”

Lu Bu had the knowledge of two thousand years later, and of course he knew what was abundant in these places he had captured.

In the Huainan area, on the bank of the Huaishui River after Zhongli, a kind of river mussel is abundant.

The mussel is broken open and the pearl can be removed from the inside.

Pearls alone can bring him a lot of wealth.

What's more, in Huainan and Lujiang, there are also rich mineral resources, where there are not only coal mines, but also huge reserves of iron ore.

As long as he occupies these places, Lu Bu will not only be self-sufficient in the future, but will even be able to sell finished or semi-finished products to foreign goods.

Such a treasure, Lu Bu said that he didn't want it, and even he wouldn't believe it!

After soaking in the water for a while, Lu Bu stretched out his hand towards Sun Ce: "Bo Fu, hand me the green salt." ”

The green salt used to wash the soot as the craftsmen bathed was placed next to it.

Sun Ce took it and handed it to Lu Bu.

Taking the green salt, Lu Bu poured some on his hand, and then rubbed it vigorously on his face.

Green salt has a strong decontamination effect, and it can be rubbed on the face, which will make the face feel hot and painful.

After cleaning it once, Lu Bu plunged into the water with a fierce son.

When he came out, he wiped his face and asked Sun Ce, "Is there any coal ash on my face?" ”

Sun Ce looked at it carefully and said to him, "There are still some ...... in the corners of his eyes."

After taking another handful of green salt, Lu Bu rubbed the corners of his eyes and his entire face and forehead vigorously again.

He felt that he was almost done, so he washed off the black water on his face like last time.

After rubbing it with green salt three or four times in a row, his skin felt a hot pain, and he finally washed his face.

When Sun Ce washed his face, Lu Bu took a small handful of green salt in his hand.

Looking at the green salt, he was even more sure that he needed to invent soap as soon as possible, so that the craftsmen who worked in the mines would not use this skin-depleting cleanser for many years.

****************************

When Lu Bu and the others left the mine, they changed into their own clothes and armor one by one.

Compared to when they went to the mine, they looked more energetic at this time.

Walking in front on horseback, Lu Bu asked Sun Ce, who was following him, "Bo Fu came to the coal mine this time, what do you think of this place?" ”

"I only heard that the coal mine is where Chuhou's treasure is located, but I didn't expect that it would be so hard to work here." Sun Ce said: "I just came out of the mine and cleaned it, but my face is still hot and painful." ”

"There are so many problems here." Lu Bu said: "If you don't solve it as soon as possible, I'm afraid that something big will happen sooner or later." ”

Sun Ce, who can be said to know nothing about coal mines, was at a loss.

He looked at Lu Bu, although his face was puzzled, he didn't ask anything.

Lu Bu smiled slightly: "Since the construction of this coal mine, I have been leading the troops outside, and I really haven't taken care of it." If I hadn't gone to the well today to take a look, I wouldn't know what would have happened in the future. ”

"The big thing Chu Hou said is ......," Sun Ce finally couldn't help but ask.

"Except for a few places where coal can be mined on the ground, most of the coal mines have to be excavated underground." Lu Bu said: "This is the case with the coal mines in Xuzhou, since they are underground, there will definitely be various situations......

Originally, he wanted to explain to Sun Ce the associated gas of coal, as well as the pressure brought by low pressure on the roadway, which could easily cause gas outbursts, roofing, landslides and other accidents.

On top of that, the further down you go, the more complicated the situation becomes.

If you accidentally dig through the underground river, not even a single craftsman in the entire coal mine will want to come out alive......

Coal mines, indeed, are dangerous places!

Knowing that Sun Ce didn't have the knowledge of two thousand years later, and he wouldn't understand these things when he told him, Lu Bu stopped explaining and grinned at him: "As long as Bo Fu knows, working in the coal mine, he may lose his life at any time." What we can do for the craftsmen is to try to solve the hidden dangers that are easy to lose their lives in advance. ”

Even if Lu Bu explained it very clearly, Sun Ce, who didn't have this knowledge, couldn't figure it out.

When Lu Bu said such a vague concept, Sun Ce was even more confused.

But he had already explained, and Sun Ce didn't want to ask too much, so he could only follow him in the direction of Pengcheng.

When I came out of Pengcheng and arrived at the coal mine, it was still early.

After such a long delay in the coal mine, they returned to Pengcheng, and dusk had come.

Before entering the official mansion, Lu Bu instructed the guards: "Invite Chen Gongtai here, and say that I have something important to discuss with him." ”

After the guards left, Sun Ce asked him, "Marquis Chu, seeing that it's getting late, isn't it a bit ...... to invite Chen Gongtai over?"

"Something?" Lu Bu interrupted him.

"The matter of the coal mine is not overnight, I think the most urgent thing to do at the moment is to train the soldiers and horses as soon as possible and prepare to face the upcoming strong enemy." Sun Ce said: "In case Xuzhou can't be saved, what Wenhou did in the coal mine will be meaningless." ”

"Bo Fu is right." Lu Bu nodded: "But the matter over there in the coal mine still has to be resolved as soon as possible." I have now prepared everything I need, in case Xuzhou can't hold it, I will send soldiers to burn the coal mine before leaving. Cao Cao and Yuan Shao didn't know how to mine coal at all, and as long as they dared to take over, I could conclude that the craftsmen who died in it every year would definitely not be a small number. ”

Staring into Sun Ce's eyes, Lu Bu then asked, "Could it be that Bo Fu thinks that there are other people besides us who can transport coal from under the mine?" ”

"Before Chu Hou, it was true that no one had mined coal." Sun Ce replied: "Since Chu Hou thinks that he should do this, I don't dare to say more. ”

"Strong enemies are coming, and what worries me the most is not that they are too strong, but that we ourselves are unstable." Lu Bu said: "In the battle of Xiapi, I suffered the loss of my own family, and if the coal mine made a mistake when we resisted a strong enemy, it would be much more difficult to fill the gap at that time than now. ”

What Lu Bu said was impeccable, and Sun Ce could only nod his head.

waved his hand at Sun Ce: "You've been with me for more than half a day, and you're tired." You still have to train to relieve the troublesome soldiers, and it's been very hard lately, so you better go back and rest early, and you don't have to take care of it here. ”

Sun Ce agreed and retreated.

Leaving Lu Bu's study, Sun Ce walked a short distance along the path, and he saw Chen Gong hurrying towards this side under the guidance of the guards.

Seeing Sun Ce, Chen Gong asked, "Where is Bo Fu going?" ”

"It's not early, Chu Hou wants me to go back and rest first." Sun Ce replied.

"Do you know Bo Fu, what did Chu Hou call me over for?" The guard just said that Lu Bu had something important to discuss with him, and he didn't explain what the matter was, and when he saw Sun Ce, Chen Gong certainly wanted to ask about it.

"I don't know very well what Chu Hou is going to do when he invites Chen Gong over." Sun Ce replied: "It's just that today he took us to a coal mine, and he mentioned it on the way, saying that there are many things that need to be rectified, and if we don't do it now, there may be a big incident in the future." ”

Although Sun Ce didn't understand what he said too clearly, Chen Gong immediately thought it clearly, Lu Bu was dissatisfied with the coal mine, so he invited him here.

After saying goodbye to Sun Ce, Chen Gong came to Lu Bu's study.

Before entering the room, he saluted Lu Bu: "I heard that Chu Hou went to the coal mine today?" ”

"Exactly." Lu Bu came to him to discuss the matter of the coal mine, and he asked first, so he stopped beating around the bush and said to him: "I went to the coal mine and saw the windbags that the public platform ordered people to install and the bathing pool prepared for the craftsmen. ”

"I don't know what Chu Hou thinks?" Chen Gong asked.

"Excellent, of course." Lu Bu replied: "If it weren't for the public station to do this, I'm afraid that no one would be able to enter the mine at all." However, I also think that there are too many things that need to be rectified now, and you need to allocate some manpower to us, and I will personally supervise the construction. ”

"When the Marquis of Chu led the troops to the expedition, I went there twice in three days." Chen Gong replied: "Every time I go to the mine, I feel a little creepy, and I always feel as if something is missing......

"It's more than a star." Lu Bu nodded: "The public platform thinks it's creepy, because it feels that something big will happen there sooner or later." ”

"After Chu Hou said this, I also felt that it was like that." Chen Gong said: "The mine is too stuffy, and the craftsmen are working inside, and it is inevitable that something will happen. ”

"It's just stuffy, and I don't need to invite the public to come over." "There's a lot of infrastructure that needs to be built in the mine. You allocate some manpower to me first, and then I will ask you to buy some things, which can not only be used in the mine in the future, but also handed over to Zhang Shiping to take out the goods and sell. It's definitely going to make more money than selling toothpaste. ”

*****************************

Lu Bu lifted the toothpaste, and Chen Gong's eyes lit up.

When he invented toothpaste, almost no one was optimistic, but in the hands of Zhang Shiping, toothpaste became a popular commodity.

Nowadays, toothpaste is no longer a luxury that only nobles and nobles can afford, and even ordinary people use it to clean their mouths in their homes.

Lu Bu said that he could make something better than toothpaste, and Chen Gong certainly wanted to ask clearly: "Dare to ask Chu Hou, what is more profitable than toothpaste?" ”

"Have you ever used a honey locust in the public station?" Lu Bu didn't answer directly, but asked like this.

Chen Gong asked with some astonishment: "Could it be that Chu Hou is planning to sell the honey locusts?" ”

"Of course not." Lu Bu shook his head: "Honey locusts are born and can be used, although they are convenient, but the stock is not much. If you want to popularize honey locust, it is as difficult as the sky. What I'm going to make is something called soap. ”

"Soap?" Having never heard of this term, Chen Gong asked suspiciously, "I don't know what the use of this kind of thing is?" ”

"Just mentioned honey locusts, and the public station actually forgot about it." Lu Bu smiled slightly: "Soap is used to wash clothes and bathe, which can remove more dirt. I hadn't thought of making it yet, but it was when I went to the mine and used green salt like the craftsmen that I felt I had to make something like this as soon as possible. ”

"I don't know what Chu Hou needs?" Chen Gong asked.

"Find some fat from pigs, cows and sheep, and get me some alkali powder." Lu Bu said: "If you can find some more petals, spices and the like, of course it would be great." ”

"I'll tell someone to do it." Chen Gong agreed, and then asked Lu Bu: "I don't know what kind of manpower Chu Hou needs?" ”

"Stonemasons, blacksmiths, and carpenters, find me a few skilled ones." Lu Bu instructed: "It is better to find some cobblers and tailors." In addition, some burlap cloth will be procured for me, and it will be sent to the mine first, and I will be of own use when I arrive. ”

"Stonemasons and tanners and tailors are easy to find." Chen Gong said with some difficulty: "But carpenters and blacksmiths are not easy to divide now. ”

"What's going on?" Lu Bu asked: "In the great Xuzhou, is it possible that there are no carpenters and blacksmiths?" ”

"Has the Marquis of Chu forgotten that he had previously instructed him to build a thousand repeating crossbows within a month?" Chen Gong said: "The carpenters and blacksmiths of the entire Xuzhou are busy with this matter. It's not easy to allocate a few. ”

"There are so many carpenters and blacksmiths in Xuzhou, if they can't make a thousand repeating crossbows a month, they might as well go outside the city to farm in the future." Lu Bu said: "I don't have many people, three or two carpenters and blacksmiths are enough." Can't three or two people be drawn out? ”

"Three or two people shouldn't be a problem." Chen Gong replied: "I'll go and arrange it for Chu Hou." ”

Lu Bu nodded and watched Chen Gong leave.

Leaving the study, Chen Gong didn't care that it was getting late, and immediately went to Lu Buzhang to ask for everything he wanted.

PS: In order to avoid the lack of power in the future, starting from today, the five changes per day will be changed from 2,000 words per day to one per day and 10,000 words per update. Since the chapter is calculated according to the number of words, the 10,000-word large chapter is equal to the 5 chapters and 2,000-word small chapters.
