Great Song

When Qian Yi came from Taitai Hospital, he was faced with a group of solemn looking people who seemed to have something important to do.Wait, why even Han officials are here, could it be something important?

Zhen Qiong didn't let him guess, and directly told the difference between the carbon gas she discovered.As soon as Qian Yi heard it, his face changed: "The real charcoal poison is colorless, odorless, and not melted into water?"

"Isn't it..." Zhen Qiong wanted to say something else.

Cold sweat broke out on Qian Yi's forehead: "Princes in the palace often die in winter and spring."

Now, except for Zhen Qiong, everyone's expressions also changed.Han Miao immediately said, "Is this serious? What kind of charcoal is used in the palace?"

"The formulations have been different over the years, but they are all high-grade hard charcoal with little smoke." Qian Yi couldn't help sighing, "Everyone in the world thinks that poisonous charcoal has smoke, but who would have thought that this thing could be colorless and odorless. Maybe let me see your method of burning charcoal?"

At this time, Zhen Qiong finally realized that something was wrong, and without hesitation, she took everyone to the alchemy room and redid the charcoal burning experiment.It is still a comparison between charcoal powder and charcoal block, put the rabbit in it, and the difference in reaction is immediately apparent.After the experiment, Qian Yi specially took the poisoned rabbit, inspected it carefully, and finally sighed: "I'm afraid I can't fake it, I have to go back to the imperial hospital and ask my colleagues to take a closer look. If it's true, I have to report it immediately." Ming officials are the ones!"

This is a major matter related to the safety of the heavenly family and the succession of the descendants, how can they not report it as soon as possible?

Hearing this, Han Miao immediately said: "If it can be verified, I would like to ask Bachelor Qian to write an article and publish it on the "Beijing News". This matter is about life and death, and the world must not let it know."

Anyway, "Beijing News" is also a newspaper run by the imperial court, so its popularity and credibility are beyond words.After it is published, their "Ri Xin Bao" will reprint it, and the scope of dissemination will be wider.As for dissemination to the world, it still depends on the emperor's order to issue the Dibao, which is not something they can say.

Qian Yi naturally knew the seriousness and nodded immediately.Don't stay in Baoying Temple for too long, then you can go back to the palace.This charcoal poisoning experiment is still somewhat dangerous, so Zhen Qiong asked Qingfeng to follow, bringing a full set of equipment.In case of need, I can always demonstrate it to the imperial doctors of the Imperial Hospital.

After a commotion, Zhen Qiong, who was injured, was about to go home to recuperate.Chi Liaozi didn't stay any longer, gave some careful instructions, and sent the two of them to the carriage.

When he was in the car and there were no outsiders, Han Miao held Zhen Qiong's injured hand and remained silent for a long time.

Zhen Qiong glanced at the people around her, and said cautiously: "Brother Miao, I was being careless. I will wear protective clothing properly from now on, and I will never be sloppy."

Han Miao looked at him, but couldn't open his mouth.A small glass vessel can hurt people. If the pill furnace explodes, is it useful to wear protective clothing?But let him go home and stop alchemy, but he can't say anything.After all, what Zhen Qiong learned is the Dao, the knowledge that can understand the principles of heaven.Just like today's encounter, if the cause of the charcoal poisoning can be explained clearly, I don't know how many lives can be saved.I interrupted rashly, I am afraid that I will be punished by God.

After a long silence, Han Miao finally sighed softly: "I don't think I would object to Qiong'er's dedication to the Tao. But don't forget, there is someone waiting at home."

This is said lightly, but inside it is extremely heavy.Zhen Qiong's breathing stopped slightly, and then she firmly held Han Miao's hand and nodded.

This time, Han Miao's expression also relaxed slightly.After a while, he suddenly asked, "Is there charcoal poison in the lamp oil refined earlier?"

Zhen Qiong thought for a while, and then said: "There should be. The carbon gas cannot be fully burned, and black smoke will be produced, and the flame will also turn yellow. It is somewhat similar to lighting the lamp oil."

"What about refining lamp oil? Is it dangerous?" Han Miao asked closely.

Zhen Qiong's face changed immediately: "It's really a little bit. I have to change the kiln when I go back!"

That is refining oil in a kiln, and the scale is not comparable to that of a mere glass dish.It would be unimaginable if the accumulated qi met the fire.Fortunately, when refining lamp oil, nothing went wrong.

Han Miao also said after hearing the words: "The oil refining workshop should be rebuilt in the suburbs. I will find someone to choose a place near the river. There is also a soap making workshop, and they will also move there."

Before that, Han Miao had already bought a field with oil in Yanzhou, and began to collect oil and refine lamp oil.The matching glazed cups are almost ready, and I plan to start selling them during the Lantern Festival.Now that there is a sudden problem of carbon gas deflagration, it is necessary to be more cautious in refining lamp oil.There is also soap making, which is also a safety hazard, so it is better to move out of the city together.

Zhen Qiong had no objection to the proposal.Han Miao thought for a while, and then said, "Before you said that you could use a chimney to emit poisonous gas. What should I do if I replace it with a brazier?"

It is not surprising that the cooktop in the kitchen has a chimney.But what's the point of making a chimney for a brazier?It is necessary to guide the air to the outside. Is it possible to use iron pipes?

This Zhen Qiong is familiar, and immediately said: "Aren't there a lot of coal fires now? You can get a refractory brick liner, beat the coal into coal paste, and press mold it. The outside can be made of copper or iron, and you can put one in it." The tin chimney is enough to guide the air out of the house. It is convenient to put this thing in the house, and it can also boil water.”

This kind of coal stove was very popular in Dayi Dynasty.Even their small Taoist temples still burn coal for heating in winter.As long as the chimney is vented, poisoning is less likely.

Pressing coal cakes is extremely troublesome, but building such a coal stove doesn't seem to be a lot of trouble.Listening to Zhen Qiong's eloquent talk, Han Miao also nodded slightly, with a plan in mind.

"What did you say? The prince died early, because of charcoal poisoning?" Zhao Xu almost didn't stand up from the throne, and his face turned black.Isn't the charcoal used in the palace all high-quality materials that have very little smoke, are resistant to burning and will not burst into dust?Why is there still smoke?

Qian Yi looked solemn, and said in a deep voice: "This is obtained by refining Qi from Lingxiao, a scholar of Baoying Temple. This charcoal poison is originally colorless and odorless. As long as the room is airtight, it will kill people. There are several types of charcoal used in the palace. , I have tried it all, without exception, they can all produce charcoal poison, put it in dogs and rabbits, and they will die in a short time. Even if the charcoal poison is weak, it will leave symptoms and die after a few days. Records of Chen Guan over the years , most princes die in winter, I'm afraid it has something to do with this matter."

He speaks clearly and has tested on living things.More importantly, this was something Ling Xiaozi verified.Zhao Xu felt his heart tighten: "Is it useless to put a water basin?"

The charcoal basins in the palace are all separated from water to remove smoke, so it doesn't work?

"This substance is insoluble in water. It can only be dissolved by guiding the smoke out of the house or ventilating it. It is best not to put a charcoal basin in the house at night." Qian Yi immediately said, "Besides, the quilt is too tight in winter to cover the nose and mouth. It can also easily suffocate the baby."

He actually checked the records in the palace and discovered this problem.If people live according to vitality, then covering their face with a quilt, wouldn't it be difficult to breathe?Adults are fine. Babies are weak, and if they are covered with a quilt, there is a high probability that they will get sick.

Is there any reason why it is difficult for the heirs in the palace?Zhao Xu felt his body tremble.At that time, Renzong either couldn't give birth to children, or couldn't raise them, and all of them died young.If it was really caused by charcoal poisoning, how many children in this palace died because of it?

"Quickly pass on the order that the charcoal basin can no longer be placed in the bedroom! Especially the palace of the empress dowager, the empress dowager and the empress! Also, let the general supervise the trial production of a new charcoal basin. It can no longer be separated from the water, and the smoke must be led out of the house! "Zhao Xu was really frightened.His queen is pregnant, if something goes wrong, it will be regrettable!

Immediately, some palace people rushed out of the hall to pass on the emperor's oral order.

Qian Yi heaved a sigh of relief, and said again: "I want to write a short article on this matter and publish it in the "Beijing News". I also ask the officials to agree."

"I agree!" Zhao Xu said immediately, "There is also the residence newspaper, and we must publish this matter, and spread it to the prefectures and counties as soon as possible, and we must not cause any more trouble."

The twelfth lunar month of winter is the season for burning charcoal.I don't know how many people rely on charcoal basins to keep warm.In the palace, there are thick silk quilts, so what can the common people rely on?Isn't there a fire to keep warm at night?I only hope that the news published in the newspaper can save more lives.

Under the urging of the emperor again, the new issue of "Beijing News" was published two days ahead of schedule.Qian Yi's article was placed at the beginning of the magazine.Immediately, the "Ri Xin Bao" reprinted it, and the danger of charcoal poisoning spread throughout the streets and alleys in an instant.

For the people of Tokyo City, this is terrible news.Who would have thought that charcoal poison could not even melt in water.Wouldn't the protection in the early years be in vain?Immediately someone got up, didn't even listen to the report, and ran home to inform the family.Others wept bitterly, saying that they had just found out that relatives in their families died of charcoal poisoning.Who doesn't use a brazier to keep warm in winter?Suddenly, old and weak women and children fell ill, with nausea, vomiting and headaches. They thought they had caught the wind, and recuperated in the house, but eventually died.Now that I think about it, I'm afraid it wasn't the charcoal basin that was born for heating, but the culprit!

For this uproar, the Han family glass mirror shop also reacted extremely.Go to the door in person, find those customers who have made glass windows, explain the charcoal poisoning, and can change the windows for free.

Those who can use glass windows, which one is not the rich and powerful?Hearing this, his face turned pale.Fortunately, the glass of Han's shop is transparent, most of it is installed in the study room, and a small amount of colored glass is also installed in the embroidery room of the boudoir, so it did not cause any trouble.And this matter is no wonder to the Han family, who didn't know the origin of the charcoal poison just after reading the "Beijing News"?On the contrary, the Han family is trustworthy and visits the doors and windows one by one, which is very rare.

And the guy in the store also said that the owner is developing a new type of brazier, which can lead the smoke outside.Immediately, many people felt Anton in their hearts.Such a big store is just a reliable store!

The Han family's glass and mirror shop was so busy that the nobles who had repaired the glass windows before all started to renovate the house.I don't know how many shops who installed glass windows for people were also forced to move.The theory of charcoal poison spread throughout the streets and alleys.This charcoal poison is terrible, but how can anyone not burn charcoal in winter?If you have to turn off the fire at night, what if you get sick from the cold?

I don't know how many blacksmith shops have begun to think about how to make new-style charcoal basins.It was the Han family shop that had been promised before, and it was the first to take out the samples.

"Why is this coal stove so square?" Zhen Qiong was also dumbfounded looking at the new-style coal stove that looked like a cabinet in front of her.Shouldn't coal stoves be round?He had heard before that the inner tank of the refractory brick was fired into a cylindrical shape, so why is the outer shell really square?

"The round furnace is cramped and not imposing, and most nobles won't be able to use it. The square one is better." Han Miao explained with a smile.It didn't take much time to make this coal stove.Alchemy requires fire-resistant bricks and tiles. He found a few people who are good at managing alchemy furnaces, and quickly made the inner liner.As for the shell, he did not listen to Zhen Qiong's suggestion and chose the style of a low cabinet.The flue for ventilation above is made into carved curved columns, which are placed in the room like a piece of furniture.Of course, there is still a place to put the copper pot on it, and if you put it in the house, you can drink hot water at any time.

This is really only used by rich people.Zhen Qiong was stunned for a while, then suddenly said: "Shouldn't the ordinary ones be made?"

"No need. When this coal stove comes out, there will be countless people imitating it. Most of them are made by small workshops, but there is no need to compete with them." In order to save their lives, I don't know how many people are looking forward to the appearance of a new type of charcoal stove.His coal stove will definitely be imitated in the future, and a more economical style will be changed.Because it is a must-have item, it will soon fall into a price war, and the profit will not be very high.It would be better to make such luxurious ones and sell them exclusively to rich people.

Sighing, Han Miao said again: "It's just that there are poor families who can't afford the charcoal stove. They don't have warm clothes and bedding in winter. I'm afraid they will use a brazier to burn firewood and charcoal."

In order to promote the incident of charcoal poisoning and wounding people, Han Miao did his best, but there are so many poor people in the world, and it is really impossible for him to save them.

After hearing this, Zhen Qiong said: "In the future, if cotton is planted and quilts are worn, maybe it will be fine."

Han Miao was taken aback: "Doesn't cotton have seeds? Stuffed into the quilt, it might weigh more than ten catties. Besides, this thing is not cheap, is it?"

He knew that Zhen Qiong planned to use the land acquired in exchange for national debts to grow cotton, and he originally thought that he was thinking about it because of the high price of cotton cloth.I never thought that the other party planned to use this thing to make bedding.

"You can remove the seeds, build a machine, remove the seeds, and then play it well, it will still be very warm in winter. As for the price, if you plant a lot, maybe it won't be expensive?" These are really not understood.However, in Dayi Dynasty, the price of cotton was not expensive.Even if the family is poor and cannot afford cotton-padded jackets, cotton-padded quilts can still be bought with money saved.

Hearing what he said, Han Miao was slightly taken aback, but became interested: "I'm going to send people to the Western Regions to find cotton seeds! If it succeeds, it will be a meritorious deed to benefit the world!"

Cotton can really have this effect, and it can be grown in Qinzhou, countless merchants will be moved.If the emperor knew about this, he might also promote cotton planting.At that time, all the poor people in the world will be happy.

The author has something to say: During the Ming and Qing Dynasties, many princes and princesses died of carbon monoxide poisoning in the palace, and it was the same in the Song Dynasty.There is no way, the airtightness of the buildings in the palace is too good, as long as charcoal is burned, accidents will inevitably occur.Moreover, in ancient times, babies were afraid of catching cold, and there was a habit of covering their faces with quilts. It is not accidental that they died early.

Cotton planting began in the Yuan Dynasty. The well-known Huang Daopo transformed the cotton spinning process and machinery.In the Ming Dynasty, cotton planting was enforced and preferential policies were given, so that cotton planting surpassed hemp planting.
