The Princess of the Substitute Bride Strikes Back

Fu Yunxi and Mu Yibai went to the town, planning to purchase winter supplies such as coal.

The eldest sister-in-law was about to give birth, and Luo and others were guarding her closely, so everyone stayed at home.

"Husband, you see this shop seems to have coal at different prices."

Mu Yibai and Fu Yunxi came to the town together in a horse-drawn carriage. As soon as she got off the car, she saw coal displayed by vendors on the roadside. There were several bags with different prices marked on them. This made her curious. How could the coal dug out be ranked in order of quality?

"Let's go and have a look."

Mu Da stayed in the carriage while Mu Yibai and the other two walked towards the vendors.

"Would you like to see some coal? Prices are generally low this year, so why not stock up on some to prepare for the winter!"

The price of coal in the market is relatively uniform and the supply is sufficient, so vendors usually do not raise prices arbitrarily.

“What’s different about these coals?”

Although Fu Yunxi asked the vendor, he already had a rough idea in his mind. These coals of different prices obviously had different purities. Some were mixed with impurities such as soil and stones. They would probably not burn well. Perhaps they were some smaller and difficult to handle broken coals!

"These coals have different uses. Look at this high-quality coal. It has almost no impurities in it. It is very easy to burn. It can be ignited immediately with an igniter. There is no choking smoke. It is very suitable for heating. This is a little inferior and mixed with impurities. It is better for cooking. It is affordable and produces some smoke when burning. It is suitable for the kitchen. You can choose according to your needs."

The vendor explained the differences between the various types of coal to Fu Yunxi clearly.

In fact, coal is similar to grain. Different customers will certainly have different choices. The key lies in purchasing power. It is obvious at a glance that these two people are not short of money, so he focused on introducing two better types of coal.

"Then let's buy a bag of this coal for heating."

Fu Yunxi stretched out her bare hand and pointed, just in time to buy some coal back to check the quality of Lianjiang County. If the quality was good, it could be mined and sold to surrounding counties in the future, which would bring a lot of income to Lianjiang County.

If the effect is not satisfactory, she can try to improve it and let the county magistrate operate it, so that the people can use it more comfortably.

"Okay! I'll put it together for you right away!"

The big customers were very generous and immediately gave them a whole bag of high-quality coal, and the vendors entertained them with a smile on their faces.

"Mu Da, come and carry this onto the carriage."

There was a lot of coal stored in Fu Yunxi's space, but she still insisted on buying it. She had her reasons, and Mu Yibai did not interfere.

"Madam, do you want to go back and try out the quality of the coal mines in Lianjiang County?"

After Mu Yibai and Fu Yunxi got on the carriage, he asked.

"Yes, the climate in the northern part of the Great Wall is generally cold. Coal can be sold to surrounding counties after being properly processed. I also want to see how this coal is different from others."

The quality of coal may be related to the quality of the coal mine. In her space, there are not only the supplies collected along the way, but also the coal prepared by Yibai in advance. The quantity is quite considerable, but she still wants to explore the quality!

"Well, I've examined this high-purity coal. It's of pretty good quality. I think it will burn without much smoke, so it's fine for indoor heating."

Mu Yibai explained his own views. Although he had been fighting on the battlefield for many years, his family was a marquis's mansion after all, and their food, clothing and daily necessities were quite good. In the past, the Mu family had always used high-quality silver charcoal for heating.

"Yes! Husband, you must have seen a lot of charcoal. What is the best quality charcoal on the market in the Great Zhao Kingdom?"

How could Fu Yunxi forget the husband in front of her? With his status and position, he would be able to get any charcoal he wanted!

"The best is the stone coal, which is considered to be of above-average quality on the market. We can try to light it when we get back. As for the top-quality charcoal from the Great Zhao Kingdom, it is often out of stock.

"For example, the silver charcoal used in the imperial palace, when lit, makes the room feel like warm spring, without any smoke or choking. The late emperor granted the Marquisate special permission to use this kind of charcoal, so Madam still has some in the storehouse supplies that she confiscated. You can take some out for comparison when you get home."

Coal has a very long history. It is used in metallurgy and iron smelting as well as in heating in every household. The State of Zhao also developed several coal mines and mined many varieties.

"Oh? I never noticed that there was that kind of charcoal in the warehouse before. Let's study it together when we get back!"

Fu Yunxi was quite interested in this coal mine. After all, it was a non-renewable resource and must be used well. It would be a pity if it was wasted or not utilized to its maximum potential.

If the research goes smoothly, she plans to invite the county magistrate to invest in the technology. This is an industry with great potential. There is only one coal mine within hundreds of miles in the northern region. Not to mention Pingyang County next door, if Shunfeng County can produce high-quality coal, it will reap a huge income.

"it is good!"

Mu Yibai looked at Fu Yunxi with eyes full of doting. Seeing her excited look, he knew that her little head was thinking of something new again.

--

"This silver charcoal is really top-grade! There is really no smoke after it is lit. I'm sure it's very unlikely to cause gas poisoning. The emperor will really enjoy it."

As soon as Fu Yunxi returned home, she couldn't wait to light the silver charcoal in the space. With the help of the ignition agent, it ignited quickly, the whole thing turned red, and after burning for a long time, it turned silver.

"This charcoal was presented to the emperor by Donghai County. Donghai County is located in the northeast of the Great Zhao State and has an inherent geographical advantage, so the charcoal produced is of high quality. Later, it became the exclusive coal for the royal family and never appeared on the market again."

Mu Yibai knew some basic information about it.

“Well, geography is crucial.”

Fu Yunxi knew that what Mu Yibai said made sense, because she had just taken the time to look up relevant books in the space.

Coal is formed through a series of biochemical reactions and geological actions of underground materials, which are then precipitated over a long period of time.

Therefore, the quality of coal itself is closely related to the geographical location, and there was no smelting technology in this era.

The coal mined in Donghai County is of high quality, which is a natural advantage. Although the coal in Lianjiang County is inherently inferior, it will be a good thing if it can be compensated by technology in the future!

"Madam, try the charcoal we bought today."

When the silver charcoal was almost burned, Mu Yibai handed the bag of charcoal he had just purchased to Fu Yunxi to burn.

"it is good."

Using the same igniter and the same amount, it seems that the burning time is a little slower. Fortunately, the problem is that there is still a faint smoke after burning, and a clear smell of carbon monoxide can be smelled.

If this charcoal were placed in an ordinary household, it might be considered excellent, but a wealthy family would surely still pursue greater perfection!

“Sure enough, I could tell the difference between the two types of coal when I compared them. I think the impurities might be too high.

Fu Yunxi expressed his idea: "I hope to develop a method to refine coal so that the coal combustion effect is comparable to silver charcoal, and then target high-end customer groups. I believe the market potential is not small."

"Okay, Madam, I support you. Madam, you have an idea, and you can leave the dirty work to me."

"Ok!"
