After putting honeycomb coal on the large stove that was built, there was no need to add firewood in the middle of a meal.

Not only does it take a long time to burn, but it is also very small in size, making it very easy to carry.

One cart can pull hundreds of pieces of honeycomb coal, and there is no need to pull dozens of truckloads of firewood to follow the large army.

Not only that, but there are also people who are arranged to guard it in case the enemy army sneaks up and light firewood.

Now it is good to use honeycomb coal, even if you throw a torch in, it cannot be lit immediately, and it is also convenient for transportation.

The whole army used honeycomb coal.

However, Li Yuanqing specially explained that the windows must be opened for ventilation, otherwise they will be poisoned by gas.

The benefits of coal far outweigh his disadvantages, and when selling the stove, the shopkeeper will make a special account to make sure that the customer knows about it, and that he presses his handprint before selling the stove.

Whether it is in the army or in Sangcheng, there is propaganda everywhere, although coal is easy to use, but pay attention to ventilation.

Almost all adults and children know this, so no one has been poisoned by gas so far.

It may have something to do with the fact that it's summer, and everyone sleeps without closing the windows.

After winter, there will definitely be people who will be disobedient.

To keep warm, the stove is brought into the house, and the windows are closed, or only a small opening is left for ventilation.

For this, Liu Paner also thought of a countermeasure.

Start promoting the ondol!

Mrs. Drey's name is very useful, and she was very curious to hear that a small amount of firewood can warm a room.

The method of making the ondol was also announced, and because it was easy to make, it spread quickly.

Ordinary people use mud bricks, and if they have materials at home, the materials used can be better.

The people of the entire Mulberry City, and even many places, began to prepare.

Liu Paner's reputation is very high, so much so that what she wants to promote can be quickly promoted among the people.

By the time General Zhao and Gu Shao arrived, they had already felt that Sangcheng and many places in the north had undergone major changes.

When General Zhao saw Li Yuanqing, he patted Li Yuanqing on the shoulder hard, "Yuanqing, Your Majesty sent Zhao over not to share your power, but to take Beiyun City in one fell swoop." ”

"In addition, His Majesty also personally explained to Zhao, I must explain it to you in person. I trust you as always, and I don't have the slightest doubt. ”

Li Yuanqing's attitude was also very respectful when he heard this, and he bowed, "With the general here, Yuanqing can also be more confident." Weichen thanked His Majesty, and his trust in Yuan Qing will inevitably be loyal to His Majesty as always. ”

"This is indeed a once-in-a-lifetime opportunity, if I can take Beiyun City in one fell swoop, it will be of great benefit to my Great Zhou. Wechen must do his best and dare not slack off. ”

General Zhao was also quite happy to see that Li Yuanqing had no complaints.

"Without further ado, let's start discussing how to do things now. Tell me all the information you've gotten lately, and we'll study it together. ”

Of course, Li Yuanqing is willing to share it with General Zhao, after all, the stakes are very high, and there is no room for mistakes.

With General Zhao stabilizing the rear, Li Yuanqing wanted to capture Beiyun City, so he didn't have to worry about the emptiness of the rear.

Li Yuanqing took General Zhao to the side of the huge detailed Kanyu map, "General, we have obtained all kinds of information recently......

Li Yuanqing talked as he could, and combined with this information, he was prepared to make arrangements and responses.

General Zhao listened carefully and gave his own views and suggestions from time to time.

Before I knew it, I chatted for an afternoon, and I couldn't get enough of it.

General Zhao was even more surprised when he heard Li Yuanqing's narration.

This time, he felt that even if the defense map of Beiyun City that Ramor got back was fake, Li Yuanqing would be able to take Beiyun City.

It's really Li Yuanqing's method, it's really good.

His Majesty's trusted courtiers are really not ordinary.

General Zhao praised, "Yuan Qing, you are really good, you have lived up to Your Majesty's trust." Whether we can take back Beiyun City this time and establish immortal achievements depends on whether we can succeed this time. ”

Li Yuanqing said with a smile: "Li must do his best." ”

Gu Shao and Yuan Governor over there are also explaining in great detail.

Gu Shao listened very carefully to Governor Yuan's words.

Not only that, Gu Shao raised some questions, and Governor Yuan could also give good answers.

"Is this coal really that good?" Gu Shao asked, "Can you show me?" ”

Governor Yuan responded, "Of course, Master Gu, wait a while, I'll ask someone to bring the stove." ”

Gu Shao waved his hand, "No need, the stove must not be light, I'd better go over and take a look, just to see how to use it." ”

Governor Yuan was stunned for a moment, but he didn't expect Gu Shao to be so approachable, so he nodded and replied, "Okay, Master Gu, you come over with the lower officials." ”

When he arrived in the kitchen, he saw the extra-large briquette stove, which immediately made Gu Shao's eyes light up.

"Yes, this thing does work." Gu Shao praised, "This coal has so many holes, is it specially made?" ”

Governor Yuan replied: "This is honeycomb coal, made of those useless pulverized coals. It's cheap and burn-resistant. Now almost all of the city uses this, only in some special places, with firewood. ”

Gu Shao nodded, "The mountains and forests in the north are not dense in the first place, and the more you cut down, the more barren the mountains will be." ”

Yuan Zhifu thought so, "Yes, now people who cut firewood for a living are going to make honeycomb coal and coal mines, making more money than before, and the protective measures are also done well." ”

Early the next morning, Gu Shao went to the field again.

This year is quite smooth, seeing that the summer has passed, the crops in the fields have grown taller, and after a while, they will be able to mature.

After learning about the local crops, Gu Shao came to the sweet potatoes and potatoes, corn, and spring wheat planted by Liu Pan'er, as well as large fields of sugar beets.

He was surprised to find that the wheat grown by Liu Paner's family was obviously better than that grown by the local people.

Gu Shao took a closer look and found that the soil here was different from the soil where wheat was grown locally, and there was sand and gravel on the surface.

There is sand and gravel in the ground and it can grow so well, it should be very barren land, how can it grow so well?

Gu Shao was puzzled.

After galloping for more than an hour, I saw a beet field as far as the eye could see.

What's the use of all this?

After watching outside for a whole day, after coming back, Gu Shao found that his wife was not at home, and after asking the housekeeper, he learned that the princess went to the Grand Governor's Mansion today and came back after dinner.

Gu Shao happened to have something to ask Mrs. Derui, so he changed his clothes and came over.

Just arrived, and it happened to be dinner time.

Li Yuanqing invited General Zhao and Gu Shao to dinner.

There was a screen in the middle, and Liu Paner and the Ninth Princess were eating on the other side of the screen.

Because it was at home, Li Yuanqing could have two drinks, so he let people pour wine.

"The local chrysanthemum is white, the taste is relatively spicy, but the aftertaste is sweet, not on the top, it is really good." Li Yuanqing introduced, "You have to do your job, you can't drink too much." Let's have a drink or two. ”
