Everyone donated money to the Hexi area, which was the reason for Qiao Wanshi's drive, but it was not convenient to say too much about this matter, so the saint did not mention it again.

He said with some curiosity, "I don't know what happened to the county lord of Yifeng entering the palace this time?" ”

Qiao Wanshi replied, "The courtier brought some things to the saint to see, I don't know if the saint would like to see it?" ”

Those who can get it before the Holy One must be a good thing.

But Qiao Wanshi didn't say what it was, which aroused the curiosity of the saint.

Isn't it Qiao Wanshi who has found something good?

The rice and wheat seeds she took out were good things that could feed the people!

Sheng Shang nodded, and Qiao Wanshi took out a few grains of charcoal that had been crushed from the bag she was carrying.

These grains are about the thickness of a finger and an inch long, and because they have been carefully selected, they are almost the same size and very well-proportioned.

Holding a few charcoal grains in her hand, Qiao Wanshi's hand immediately turned gray and black.

Shengshang waved his hand, Liu Changan came down immediately, and Qiao Wanshi took out a handkerchief with her other clean hand and asked Liu Changan to cushion it.

"This thing is very easy to get dirty, Grandpa Liu should be careful." Qiao Wanshi reminded.

She got a handful of soot herself.

Liu Changan is very satisfied with this and is a clever man.

With a handkerchief, Liu Changan held a few charcoal grains and sent them to the holy table.

A few grains of charcoal on the plain white handkerchief made it even more pitch black.

The saint was about to reach out to take it, but Liu Changan immediately said, "The saint should be careful." ”

Saying that, he was about to hand over his handkerchief, but the saint waved his hand, "Wufang." ”

Two fingers pinched a grain, and the saint looked at it again and again, but he didn't figure out what it was for a long time.

"Liu Changan, do you recognize this thing?" The saint asked.

Liu Changan hurriedly shook his head, "If you go back to the saint, the slave doesn't know." ”

Shengshang asked Wang Yiyan and Huang Xu again, and the two looked at each other, so they had to take two pills from Qiao Wanshi's cloth bag and look at them carefully for a long time.

They certainly don't know what it is.

Qiao Wanshi didn't waste each other's time by selling more guanzi with the saint, she pointed to the charcoal brazier, "Can you borrow the saint's brazier?" ”

Liu Changan was a little vigilant, afraid that Qiao Wanshi would do something unfavorable to the saint, but the saint was not worried at all.

Just by virtue of Qiao Wanshi's hard-won seeds, she is not a bad person.

Shengshang nodded, "You can use whatever you want." ”

Qiao Wanshi took off the cover of the charcoal basin and poured half of the small coal in her cloth bag.

"Can the courtiers ask the saint for an empty brazier again?" Qiao Wanshi turned around and asked.

The saint nodded, and Liu Changan immediately asked someone to bring another charcoal basin, and his eyes kept staring at the charcoal basin.

Qiao Wanshi was standing by the charcoal basin, if there was anything strange about the little black particle, she shouldn't have been standing so close.

The only thing to guard against now is that Qiao Wanshi suddenly lifted the charcoal basin and poured the coals on the saint.

Qiao Wanshi saw that Liu Changan had been staring at her all the time, instead of staring at the things in the charcoal basin like everyone else, and raised her eyebrows slightly.

After a while, the maid came in with another brazier.

Qiao Wanshi took tongs and took out the charcoal grains she had just poured into them one by one, and the charcoal grains had been burned red.

Until she has taken out all the charcoal grains and brought the charcoal basin to the middle of the room.

At first, others thought it was like metal, and it could be burned red.

But after a while, the charcoal grains were still red, as if they were burning.

"This ...... Is it burning? The saint finally couldn't help but ask.

Qiao Wanshi smiled and nodded, "Yes, they are burning." ”

She poured all the small charcoal particles left in her bag into the brazier and let them ignite each other.

Qiao Wanshi didn't bring many charcoal grains, about two catties, all of them were put in a charcoal basin, and it was only a little bit at the bottom of the pot.

"Actually, I broke these charcoal grains, and the original charcoal nuggets were very large." Qiao Wanshi gestured, and her gestures were ...... It's huge.

Sheng Shang thought her action was funny, and unconsciously raised the corners of his lips.

"For the sake of aesthetics, I specifically looked for similar sizes from the broken charcoals, and some of them were specially polished. Actually, these things are not very pretty. Qiao Wanshi said.

She was honest when she said that.

The saint asked, "Is this the same as charcoal?" ”

I can make charcoal or something, but it's not too useful.

Moreover, the charcoal that Qiao Wanshi made had smoke when it was burned, and she poured less into the charcoal basin at first, and there was not much smoke.

Now she poured the rest of the bag into the brazier, and the smoke grew loud.

Looking at the smoke, Liu Changan frowned a little, I'm afraid this is not the inferior charcoal used for the kitchen fire!

Qiao Wanshi saw Liu Changan's disgusted eyes, and she was also helpless.

This is originally coal for cooking, not charcoal for burning houses.

Besides, the saint used silver bone charcoal, which was the best in the charcoal, and there was not a trace of smoke, and it was only sent in after it was burned outside.

How can these coal blocks of hers be compared to other people's best silver bone char?

"The smoke is a little bigger," Qiao Wanshi explained, "but my charcoal is very simple to make, not as troublesome as the previous charcoal, and this charcoal is very powerful and burns for a long time, and it is much better to use it for cooking than to burn firewood." If the whole country can use charcoal like mine, no, no, if all the major towns use charcoal like mine for cooking, then there is no need to buy firewood. ”

Liu Changan snorted, he didn't have a good impression of this charcoal from the beginning, this charcoal smoked as soon as it was burned, and the air in the entire Heart Cultivation Hall was smoked by Qiao Wanshi's charcoal.

"Lord Yifeng, even if these charcoals are used in the kitchen, they are not afraid of smoke, but charcoal is not fired with firewood after all? No matter how good your charcoal is, you have to make it. Since you are not afraid of smoke in the kitchen, it is better to simply burn firewood, or do you need to make charcoal? ”

Qiao Wanshi, "......"

"I don't make this charcoal with firewood." Qiao Wanshi endured the unhappiness in her heart and explained.

"And what did you make it from?" Liu Changan asked.

Qiao Wanshi continued to endure, "Father-in-law Liu, this is my secret recipe, forgive me for not being able to tell you." All I can say is that I don't use firewood to make charcoal, and I don't need to burn it. Also, this charcoal burns for a long time, much better than ordinary firewood. ”

"Then why don't you show it to the county lord of Yifeng?" The saint suddenly spoke.

Qiao Wanshi entered the palace this time to persuade the saint to come up, of course she nodded.

The charcoal she brought was packed in the carriage, and Qiao Wanshi asked the saint for her life to drive her carriage over. In the empty courtyard outside the Heart Cultivation Palace, there were two large bags of charcoal processed by Qiao Wanshi, which were all knocked with a hammer, small pieces of charcoal.

Along with the charcoal, there was also a small stove made by Qiao Wanshi.

The diameter of the stove was about a foot, and the height was only a foot and a half.

The outside of the stove is iron, and the inside is made of wheat bran and mud, leaving only a slightly thicker space than honeycomb coal in the middle.

An iron grate was placed at the bottom, with holes underneath to allow air to help the coal burn.

Such an ordinary coal stove, of course, Qiao Wanshi did not have much effort to make.

Now, she's going to prove just how good coal really is.
