As soon as the king said hello, more than 30 people gathered in a small area, and the soil they dug out was no longer carried on their backs one by one, but to the side.

A small pothole about seven or eight square meters in size can be dug down much faster.

After about half an hour, someone suddenly shouted, "Dig, dig!" ”

The people next to him all looked over, and Wang Yiyan ran over directly, kneeling on the ground and looking at the little bit of black carefully.

He picked at it, but he couldn't move, Huang Xu walked over with his eyebrows twisted, and said in a deep voice, "Get up." ”

Wang Yiyan raised his head, glanced at Huang Xu blankly, and then nodded in hindsight, "Oh." ”

As soon as Wang played, Huang Xu went down with a shovel, and when there was a sound, he also shoveled down a piece.

Wang Yiyan hurriedly stepped forward, picked up the piece of coal that he shoveled down, and held it high above his head, "County Lord, we dug it, we dug it!" ”

As he spoke, Wang Yiyan burst into tears of excitement.

This person is still the same as when he first saw the rice harvest.

After crying, Wang Yiyan wiped his face with his sleeve and beckoned the people around him, "Go on, let's all continue." ”

Seeing the coal, everyone's fatigue seemed to be swept away, and they were full of energy.

After a while, coal was seen in many places in the small pit seven or eight meters square.

The yellowish dirt was carefully shoveled away until the bottom of the pit was covered with inky coal.

"Dig some up, let's try it out." Qiao Wanshi shouted.

The people below responded, and the shovels were clattering, and the coal layer was much more difficult to dig than the yellow mud layer above.

It took a lot of effort to dig out a dozen baskets of coal and return to the surface.

"County lord, this coal is relatively hard and not easy to dig." After Huang Xu came up, he told Qiao Wanshi what he thought.

Qiao Wanshi nodded, "Coal is only slightly looser than stone, and it is indeed difficult to dig, especially if we want to dig with a shovel, it is even more difficult." ”

Not only is it difficult, but it is also a great waste of shovels, and if you dig like this, you don't know how much the shovel will lose.

The coal dug out is not as good as the wasted shovel, then the gain outweighs the loss, after all, in Jin Zhaoguo, iron is a very precious thing, and ordinary people are not allowed to use iron utensils in large quantities.

Qiao Wanshi hit those machine parts, also because she didn't use them much.

Later, Qingzhu asked for 200 sewing machines, and Qingzhu got a lot of iron by himself, otherwise the blacksmith would definitely not give him a beating.

Qiao Wanshi pondered for a moment and said with relief, "Lord Huang, don't worry, there is naturally a way to do this." ”

There are some things that Qiao Wanshi can't say casually, so she just comforts Huang Xu.

The coal on her back was very precious, Qiao Wanshi divided it and sent it to Sun Yan in a basket, so that Sun Yan could use it and feel how good the coal was.

Ten baskets were sent back to the capital, this was the coal they got on the first day of excavation, and more than half of it had to be sent to the saint.

Then there are the remaining two baskets, Qiao Wanshi asked people to take out two large braziers, pick out some of the charcoal burning in the stove, and then put on the coal knocked into small pieces to ignite, this is the fruit of their labor today, but also their hope for the future, naturally they have to burn the charcoal fire all night to celebrate!

Everyone gathered around the two large braziers, roasted the fire, ate dinner, and felt that everything they did today was worth it!

That night, Sun Yan received the coal, and according to the method of use in Qiao Wanshi's letter to him, he brought a brazier to ignite the coal, and then he kept observing.

The fire of this coal is not inferior to charcoal in terms of temperature, and with a little fan, the fire is also very strong, so that the family can stir-fry on the fire, and there is absolutely no problem.

It's just that when the coal first burns, there will be smoke coming out, and after it is burned, it will not smoke much.

This charcoal fire is not as good as silver bone charcoal for heating in the house, but it can be compared to ordinary charcoal.

Many people can't afford to use silver bone charcoal at all, even if it is ordinary charcoal, it is very economical, and when it is too cold to work, there is absolutely no charcoal fire in the house.

This kind of charcoal can be used by the common people, and if the price is cheap, there should be many people in the northern region of Jinzhao Kingdom this winter.

The more Sun Yan looked, the happier he felt.

He didn't misread Qiao Wanshi, when this Tianyun prefect, he didn't make a mistake!

Early the next morning, Sun Yan got up before dawn.

In fact, he tossed and turned all night and didn't close his eyes at all.

"Master, what are you ......" Mrs. Sun also sat up from the bed, put on her clothes and prepared to serve Sun Yan to dress and freshen up.

Sun Yan shook his head, "Madame, continue to sleep, it's still early." ”

"Then why did you get up so early?" Mrs. Sun asked.

Sun Yan was helpless, "I'm really itching, go to the county lord and take a look at the place where they are mining coal." ”

From Yunjin City to Liu Mu Town, where Qiao Wanshi is currently located, the carriage runs faster, and it will take an hour and a half.

Sun Yan set off at this time, and when he arrived at Liu Mu Town, it was already almost midday.

Liu Muzhen.

Qiao Wanshi got up, and He Chen's had already sent hot water.

"Miss, freshen up first." Ho Chan said.

Qiao Wanshi washed and rinsed her mouth with hot water, changed into light clothes, wrapped a fur coat on the outside, and hugged the soup woman prepared by He Chen in her arms, and then went out of the tent.

Huang Xu and Wang Yiyan had already gotten up, and Sikong Fan was also sitting around with them, discussing something.

Qiao Wanshi went over, and heard the insider talk about how to dig coal mines.

At present, there is no result of this matter, so Wang Yiyan asked his subordinates to dig the soil first, and no matter what, dig out the coal seam first.

As for the method, they will definitely be able to figure it out.

When several people saw Qiao Wanshi coming, they immediately greeted her.

Sikong Fan took a stool and asked Qiao Wanshi to sit first.

"Haven't you had breakfast yet?" Sikong Fan asked her.

Qiao Wanshi shook her head, "It's just gotten, Aunt He is ready to go." You're all early. ”

"We're used to going to court every day." Wang Yiyan said with a smile.

It was not yet dawn when they went to court, not to mention that they had to get up, wash, and rush to the Yellow Palace, which was about four o'clock according to the modern way of keeping time.

Even if your home is closer to the palace, you have to get up at half past four at the latest.

Several people called Qiao Wanshi and discussed it together, and what kind of pickaxes were raised.

Qiao Wanshi only listened to it but didn't say it, and the things that these people put forward were useless.

But she wouldn't interrupt, or would she be able to stop the discussion?

After a while, He Chen came over to ask Qiao Wanshi to eat.

"Two adults, let's eat some together." Qiao Wanshi invited.

Wang Yiyan waved his hand, "We've eaten since we got up, so let's go eat first." ”

Qiao Wanshi looked at Sikong Fan again, Sikong Fan definitely didn't eat.

Sure enough, Sikong Fan and Qiao Wanshi stood up together, "Two adults, I will go to dinner with the county lord first." ”
