The weather in Chang'an is getting colder, and this year is even colder than last year, and according to this situation, the first snow of this year will come earlier.

Liu Bowen came to report to Li Jing and talked about the cold weather by the way.

"Regent, this year's winter is earlier than in previous years, and the weather is getting older and colder, and if this situation continues, I am afraid that people will freeze to death."

Liu Bowen said with a sad face.

"Oh, go and ask the Taishi Bureau, how has the weather been in the last few days?"

Li Jing turned around and instructed Ximenyang.

"The minister has just come from the Taishi Bureau, and the Taishi Bureau predicts that in a few days, it is likely that there will be a heavy snowfall, and the temperature will be even lower at that time!"

Before Liu Bowen came to see Li Jing, he first went to the Taishi Bureau, and after chatting with Taishi Ling, the chief official of the Taishi Bureau, for a while, he rushed to meet Li Jing to report on his work.

The Taishi Bureau is subordinate to the secretary province, the five dynasties and the early Song Dynasty called Si Tianjian, the Yuan Dynasty called the Taishi Academy, the early Ming Dynasty continued to use Si Tianjian, and the later period was changed to Qin Tianjian.

The Taishi Bureau observes the celestial phenomena, calculates the solar terms, formulates the calendar, and Liu Bowen goes to the Taishi Bureau to understand the recent changes in the sky!

As a result, Tai Shi Ling told him that there would be heavy snow in the next few days, and the weather would be colder than ever!

"That's it! Then let everyone stay at home and not come out, don't you do it, make a fire at home to keep warm, and get through this cold winter! ”

Li Jing said.

"The regent doesn't know that the people of the Tang Dynasty need to work for a living, if they hide at home and don't come out, how can they survive the winter without food?"

"And in such a cold weather, if you want to stay at home and light a fire to keep warm, how can you get firewood without going out, even if everyone prepares enough firewood, it is easy to cause poisoning if you make a fire in the house......"

In the face of Li Jing's words, Liu Bowen was a little helpless, Li Jing rarely went outside to activities, did not understand the life of outsiders, many people need to go out to work, sell some things to get the necessities of life, to ask them to do nothing, stay at home and live behind closed doors, that is unrealistic.

Not to mention ordinary people, let's just say that the soldiers of the Tang Dynasty, in such a cold weather, they still need to patrol the streets, defend the Beijing Division, etc., and the personnel of each yamen also need to work.

You can't let them come out with other people in the house, if you do this, the whole Chang'an will be paralyzed, and if there is any emergency, no one will be able to deal with it.

"If the situation you said happens, what can you do to fix it?"

Li Jing also realized the seriousness of the problem, although Datang already has cotton, but most of it is used for ornamental use, and no one would think of using cotton to make quilts and jackets.

Fortunately, the system gave him 100,000 catties of cotton, which can be used to make quilts and cotton clothes, wool can also be made into woolen sweaters, and the hair of other animals can also be made into down jackets.

These add up to solve the winter, and it shouldn't be a big problem!

"This ...... The minister will not be able to think of any good way for a while, so it is better to find other ministers to come and discuss, maybe other ministers will have a way. ”

Liu Bowen looked embarrassed, although he is the prime minister and his level of strategy is not low, but this kind of natural disaster, he is also powerless, so he can only gather everyone to brainstorm!

"Even you can't do anything, what can other people hope for, in the court, there are a few people who can be smarter than you, and it will not end well to consult with them."

Li Jing waved his hand, he didn't plan to find anyone else, anyway, he already had a solution.

"As the so-called three stinkers, the top one Zhuge Liang, the Tang Dynasty is full of talents, and with their participation, maybe it can really solve the problem."

Liu Bowen said that he still thinks that there is great power in numbers, and everyone thinks together, there are always one or two ideas that amaze everyone, and maybe someone can think of a solution.

"To solve the problem of heating, this king already has an idea in his heart!"

Li Jing looked up at Liu Bowen and smiled.

Liu Bowen was very surprised!

He didn't expect that the first person to think of a way would be Li Jing, the regent who rarely goes out, does he really have a way?

Regardless of whether what Li Jing said was true or not, Liu Bowen still planned to listen to what Li Jing had to say first, if Li Jing's method didn't work, it would not be too late to gather everyone to discuss it together!

"The minister is stupid, please make it clear to the regent!"

Liu Bowen crossed his hands and saluted.

"Berwyn, do you know Bai Stack?"

Li Jing didn't immediately say his solution, but asked Liu Bowen instead.

"White stacks? This minister naturally knows, but what does heating have to do with Bai Diezi? ”

Liu Bowen was very puzzled, isn't the white stack a potted plant that the nobles of Chang'an used to watch? Can that thing be used for heating?

"Of course it matters, in fact, the role of white stacks is not for ornamentation, but for sewing quilts and cotton clothes."

Li Jing began to give Liu Bowen popular science, about the role of cotton, in addition to being used to sew quilts and cotton clothes, cotton also has the effect of stopping bleeding, and many bandages in later generations are made of cotton.

The large output and low production cost of cotton make the price of cotton products relatively low.

Cotton fibres can be used to make a wide range of fabrics, from lightweight and transparent voile to thick canvas and thick velveteen, making them suitable for all types of clothing, furniture and industrial fabrics.

If it is planted in a large area, the people of Datang can be used by everyone, and they are no longer afraid of the cold winter.

Liu Bowen was very surprised when he heard it! He didn't expect that the white stacks would be used so much, which was more valuable than watching.

It's just that the current Datang doesn't have so many white stacks at all, even if you collect all the white stacks in the homes of dignitaries, it's not enough.

"Although the white stacks are good, but Datang has not planted them on a large scale, even if you know the usefulness of the white stacks, you can't solve the current dilemma, even if you start planting now, it's too late!"

Liu Bowen shook his head, although it is good to use white stacks to keep out the cold, it is a pity that far water cannot quench the thirst of the near.

"This king has exactly 100,000 catties of white stacks in his hand, which can be used to make quilts and cotton clothes, don't we still have wool? It can be made into a down jacket to protect against the cold. ”

"In this way, it will not solve the problem of everyone's travel, as for heating in the house, you can let everyone build heating equipment, build a kang or something to keep warm."

"If you are worried that burning in the house will lead to poisoning, then build the stove mouth of the fire kang outside the house and surround it, which solves the heating problem and does not have to worry about poisoning, and shows you something!"

After Li Jing finished speaking, he motioned to Ximenyang to bring in the honeycomb coal stove and honeycomb coal!

Just take this opportunity to show Liu Bowen the usefulness of honeycomb coal, and in the future, he will rely on honeycomb coal to make money to increase his internal income.

As for paying taxes, as a regent, you don't need to pay taxes.

Li Jing estimated that with the coal mine in his hand, how could he make tens of millions of yuan, or even more!

Datang's mining technology is limited, except for open-pit mines, other mines buried deep underground, it is not easy to mine, Li Jing plans to sell honeycomb coal to people with a solid economy.

Thinking about those who live a tight life and don't even have a little greasy meal, they must not be able to afford it.

"Why does this black look so much like coal? But it's not the same as this one!"

Although Liu Bowen is full of poetry and books, he is not a nerd who is blind to things outside the window and only reads sage books, and recognizes honeycomb coal as coal at a glance.

"Berwyn, you read that right, this is made of charcoal, which is ground into powder, mixed with water, and then made into what you see with special tools, because it is shaped like a honeycomb, I named it honeycomb coal."

Liu Bowen nodded after hearing this, honeycomb coal! It's really apt, but what is this thing for?

"You must be wondering, why am I showing you this?"

Li Jing said with a smile.

Liu Bowen nodded and let Li Jing continue.

Li Jing asked Liu Bowen to show Liu Bowen the usefulness of this honeycomb coal.

The chamberlain immediately stepped forward, put the honeycomb coal into the honeycomb coal stove, lit the fire, and soon the honeycomb coal burned, and the chamberlain put a pot of water on the honeycomb coal stove.

"This ......"

Liu Bowen was a little surprised!

This honeycomb coal doesn't have a choking taste, and it can be used to boil water.

Then Li Jing introduced the use of honeycomb coal to Liu Bowen, of course, honeycomb coal combustion also needs to maintain ventilation, otherwise it is easy to be poisoned by carbon monoxide.

Therefore, honeycomb coal stoves should be repaired in a ventilated place so as not to cause carbon monoxide poisoning.

After listening to Li Jing's words, Liu Bowen had an understanding of the situation of honeycomb coal, and he instantly understood what Li Jing meant, Li Jing was planning to use honeycomb coal to make a lot of money!

"This honeycomb coal and honeycomb coal stove are indeed good things, the regent is planning to sell these two things, I don't know how much he plans to sell them?"

"I plan to sell two honeycomb coals for three cents, and if the quantity is large, I can also get a discount, and as long as I buy enough honeycomb coal, I will also give a honeycomb coal stove."

"And honeycomb coal can also be used in combination with ondols and fire walls, as long as the quantity purchased is enough, it can also be delivered to the door, and help employers design ondols, fire walls, and stoves for free! There is also after-sales service. ”

Li Jing gushed about how to sell honeycomb coal and how to promote it.

Liu Bowen looked at Li Jing's expression, and knew that Li Jing did not plan to put the money obtained from the sale of honeycomb coal into the treasury and leave, Li Jing planned to put all the money into his own pocket.

However, this is someone's private property, and even if all the money from the sale of honeycomb coal is really put into his own pocket, no one else can say anything.

"Since we have found a way to solve the problem of heating, the minister will not disturb the regent, and the minister will retire!"

Liu Bowen crossed his hands and saluted, said goodbye and prepared to retreat.

"Well, wait a minute, this king will have someone send Bai Diezi over!"

Li Jing plans to start planting cotton on a large scale throughout Datang next year, and he wants everyone in the world to be able to wear cotton clothes and no longer be afraid of the cold.

"Weichen represents all the people of the world, thank you Regent!"

Liu Bowen saluted again, and then said goodbye and left.
