Lu Bu decided to change the taste of the war rice, and also planned to let the men develop dry food with meat and vegetarian dishes, which shows that he also attached great importance to the diet of the soldiers.

Since he joined Lu Bu, Sun Ce also found that the soldiers under Lu Bu ate very little every day.

At least compared to the soldiers he once led, the soldiers under Lu Bu only ate one or two bowls of rice every day.

Although they didn't eat much every day, the soldiers spent a lot of money on food.

They were served meat and vegetarian dishes every day, and the average soldier ate better than the other officers under the command of the heroes.

"Take me to the coal mines." It was still early, and Lu Bu stood up and greeted Sun Ce.

I have long heard that there is a coal mine in Xuzhou, and businessmen from all over the world gather here, so they wait for the coal to be transported away immediately after the mine comes out.

At first, the merchants didn't think that there would be much to be gained from mining coal.

Zhang Shiping and his people sold coal to all parts of Xuzhou, first for some blacksmith shops, and later to the eunuchs and scholars, and then became an important fuel for the people to replace firewood.

Even when the armies went out, the fuel they carried was coal, not cartloads of firewood.

The price of firewood in the bazaar has never been very low, and it is even more expensive to burn it into charcoal.

The coal produced in Xuzhou, in addition to the green smoke when burned, is far stronger than the expensive charcoal in terms of burning time and heat generated by combustion.

The advent of coal has gradually replaced firewood, which was once the main fuel, in many places.

Accompanied by Sun Ce, Lü Bu took more than a dozen guards out of Pengcheng and came to the coal mine located on the outskirts.

Several people in charge of the coal mine, hearing that Lu Bu was coming, hurried to the exit of the mine.

Seeing Lu Bu and the others from afar, they bowed and saluted.

Coming to them, Lu Bu glanced at a few people: "You are all in charge here?" ”

"Back to Chuhou, we are all in charge of here." One of them replied.

"How's the coal mine going?" Lu Bu asked, "Are there as many people who come here to buy coal as in the past?" ”

"It's not just like it used to be." The steward replied: "The coal that is mined every day is not even selected at all, and is transported by the merchants. Even if it is a rough selection of the gangue and slime left, someone will buy it. ”

"Someone buys coal gangue and slime?" Lu Bu asked, "What's the use of those things they wanted?" ”

"It is said that it can be mixed with coal." The steward replied: "The businessman is doing things, and we don't want to ask too much." ”

"It's really business-free." Lu Bu said with a smile: "You're right, we don't care what Shang Jia does." All we have to do is that the coal that comes out of here is good, and as for how they add other things, we don't have to pay attention to it, and we don't need to pay attention to it. ”

A few stewards couldn't stop talking, and followed Lu Bu towards the mine.

When Lu Bu arrived, the gate of the mine was already open.

He had only heard that there was a coal mine in Xuzhou, and Sun Ce had never been here, and when he followed Lu Bu into the mine, he felt that everything was very novel.

In particular, there was a hill made of gangue in the mine, and the swarthy nature of the mountain made it look different from any mountain Sun Ce had ever seen.

Following behind Lu Bu, Sun Ce looked left and right, as if he wanted to come to the mine through this time and see everything in the coal mine clearly.

"What lighting is used under the coal mine today?" While walking, Lu Bu asked the steward, "There is also ventilation, how did you solve it?" ”

"Ventilation, we are using a big windbag." The steward replied: "There are special people who press the windbags on it and send the wind to the bottom of the mine. ”

Of course, Lu Bu could understand what the steward answered, but Sun Ce was confused and didn't understand what he meant at all.

It's just a coal mine, why do you need windbags for ventilation, and what lighting is needed......

Turning his head to glance at Sun Ce, Lu Bu knew that he must be full of doubts at this time.

He didn't explain to Sun Ce, but just asked: "If Bo Fu wants to find out what the coal mine looks like, just follow me to have a look." ”

"Take us to see the windbags." Lu Bu gave a command to the steward.

The steward led them to the entrance of the mine.

When they arrived at the place, Lu Bu and the others saw two huge windbags at the entrance.

Several miners were stepping on their windbags, blowing air into the mine.

After the left windbag blows up, the right windbag is then connected.

By the time the wind from the windpocket on the right had been pushed into the mine, the left had been filled with fresh air.

"Who came up with the idea to build these two windbags?" Lu Bu asked the steward.

The steward replied: "It's Chen Gong, he thought that we couldn't rely on fanning the wind into the mine, so he thought of making these two windbags......

"There are still many ways to do it." Lu Bu nodded, and then said to the steward, "Take us to the well to have a look." ”

"Chu Hou wants to go to the well?" The steward asked, stunned.

"When you come here, of course, you have to go down the well to have a look." Lu Bu said: "The most important thing in the coal mine is safety, standing here I can't see anything, only when I go underground, can I see how you ensure that the miners are thorough on weekdays."

Lu Bu wanted to go down the well to have a look, and of course a few stewards didn't dare to stop him.

The steward who took the lead timidly said to Lu Bu: "The mine is dirty underneath, if you go down, you will definitely get a face of soot, I asked people not to mine coal first, and wait until Chu Hou sees it......"

"If I don't mine, how do I know what I can't do?" Lu Bu interrupted him: "Don't say so much, get a few sets of miners' clothes, and Bo Fu and I will go down and have a look." ”

Knowing that Lu Bu had to go to the bottom of the mine to take a look, the steward had to tell the other steward next to him to find a few sets of clothes worn by the miners.

It wasn't long before the steward brought some new clothes.

Picking up a piece of clothing and shaking it open, Lu Bu said with a smile: "I'm afraid these clothes will be smaller when I wear them." ”

"Chu Hou is too burly, where can ordinary people compare." The steward who took the lead hurriedly replied: "If you rush to make clothes, I'm afraid it's too late to ......."

"You can't be asked to make a set of clothes for the next mine." Lu Bu said: "It's better to be smaller than to wear armor and go below." ”

"Chu Hou, please come here to change your clothes." The steward who took the lead asked Lu Bu and the others to change their clothes not too far from the entrance of the mine.

There were three houses that occupied a large area, and when he entered the room, Lu Bu found that there were many boxes neatly stacked in the house.
