Datang: The prince of salted fish was overheard by Li Er

Li Shimin was curious again when he heard about the cotton-padded clothes.

With the experience of the down jacket just now, he became very interested in the cotton-padded jacket that Li You said was less effective in keeping warmth, but had more volume.

"How many cotton clothes are there? Do you have samples, so I can try them too?"

But this time Li You shook his head and said: "My son went to Hexi in a hurry, and didn't bring a cotton coat with him."

"As for the exact number, I don't know. Uncle Feng is in charge of everything."

Then under Li Shimin's strong request, the two did not return to the palace, but two teams joined together and went directly to Feng Shaoshi's garment workshop.

At this moment, Young Master Feng was also on the scene to supervise, and he was taken aback when he saw Li Shimin come suddenly.

"Uncle Feng, how is the production of cotton clothes?"

Li You quickly helped him up, and asked him and Li Shimin what he and Li Shimin were concerned about.

Hearing this question, Young Master Feng also said proudly: "Fortunately, I am not disgraceful."

Then when tens of thousands of cotton-padded clothes appeared in front of him, Li Shimin was shocked.

"Are these the cotton-padded clothes that Yuer mentioned?"

After speaking, I immediately picked up a cotton coat and changed into it, feeling the warmth of the cotton coat.

These cotton-padded jackets and down jackets are basically the same style. The down jackets look more fluffy, but the real effect of keeping out the cold is also better.

If the down jacket feels like falling into a pile of warm and fluffy feathers after wearing it, the cotton jacket feels more close-fitting and has a more real feeling.

After experiencing it indoors, Li Shimin went outside again to experience the effect of the cotton coat.

Li Shimin soon came to a conclusion. Because of the design, Li You's cotton-padded jacket basically has the same thermal effect as a down jacket, but it is much heavier.

But even though it was heavier than a down jacket, it was still much lighter than a cloth robe with five or six layers.

"Great, with this batch of clothes, the people in Chang'an don't have to suffer from the cold anymore. Young commander, how many cotton clothes have you produced?"

Hearing this, Master Feng frowned slightly, and then said: "So far, 2 pieces have been produced, and there are not many remaining raw materials. It is estimated that [-] pieces will be produced in the end."

"Your Majesty, there are hundreds of thousands of people in Chang'an City, and the [-] cotton-padded clothes in this area are probably a drop in the bucket."

Master Feng will personally supervise the production of cotton clothes in the garment workshop, which are used to equip the most needed troops, so he immediately said what was in his heart.

Hearing this, Li Shimin turned his attention to Li You again.

This gaze gave Li You goosebumps all over his body.

[No way, Li Er, are you still blackmailing me? 】

[Just now I said that cotton clothes can be produced in large quantities, but that is because cotton can be grown on a large scale. 】

[I only planted so much cotton this year, and it is not bad to be able to produce [-] pieces. Next year, I will ask the Ministry of Households to grow more cotton, and then the problem will be solved. 】

Li Shimin can understand Li You's complaints.

After all, Li You is still a child now. Although he controls the power of the household department and has a talented person like Feng Shaoshi to assist him, the time is still too short after all.

However, what should the people of Chang'an City do to protect themselves from the cold?

Although Li You said that his clean coal and stove could solve this problem, but he hadn't experienced it himself, so Li Shimin still hesitated.

"Your Majesty, in fact, the people can use the stove to keep out the cold. Now that the Shence Mansion and Chu Palace have installed stoves, it is very warm!"

Master Feng saw Li Shimin's worry, and said quickly.

Although these clean coals and stoves were not sold outside without Li You's order, they did not hinder the use of the palace itself.

With the help of Haig and a physics teacher, Shence Mansion and Chu Wang Mansion have completed the renovation of the entire palace, and the stoves have been arranged in all the rooms.

Hearing that Master Feng also praised Huolu, Li Shimin immediately became interested and said: "In that case, Yuer, let's go to the palace again."

Before entering the gate of King Chu's Mansion, Li Shimin felt a slight difference.

At this moment, the snow was knee-high, and except for the main road that had been cleared out, the corners of the houses were basically covered with snow.

The weather is so cold that everyone wants to sit at home, and will not go out unless it is absolutely necessary, and of course they will not come out to clean the snow in the corner.

But it is completely different outside Chu Palace.

Not only was there no trace of snow falling, but the fallen leaves on the ground were also swept clean.

When Li Shimin was still thinking about why, the gate of the palace opened, and he immediately understood.

Just when the outside world was still putting cloth robes and linen shirts on their bodies, the Chu Palace had already realized the freedom of cotton clothes.

A padded upper body not only resists the cold, but also does not affect the action at all.

To receive such preferential treatment, the servants of the palace naturally cleaned it with extra care.

Li Shimin entered the palace with emotion. He didn't feel any difference in the courtyard at first, but after entering the room, he felt the difference.

A heat wave hit, making the down jacket on his body smell bad in an instant.

"It's such a small room, how much charcoal is lit!"

"Such a waste!"

"Young master, it's not like you don't know what's going on with the fuel in the capital, so why don't you allow them to waste like this."

"Besides, the temperature in this room is obviously not just ignited. You'er is not in the palace, why are you like this!"

While taking off his down jacket, Li Shimin complained like a cannonball.

Faced with Li Shimin's complaints, Young Master Feng was unmoved at all. He walked to a stove in the corner with a smile and said, "Your Majesty, what we burn in this stove is not charcoal, but briquettes."

"Please take a look, Your Majesty!"

Hearing this, Li Shimin hurried to the stove, and at the same time found the briquettes placed beside the stove.

Feeling the astonishing heat from the stove, Li Shimin also asked his doubts.

"You'er, I heard that when these coals burn, they will emit thick smoke. Why doesn't your stove have one?"

Li You smiled slightly and said, "Your Majesty, my son, the coal has been desulfurized, so naturally there will be no black smoke."

For a while, Li You couldn't find any easy way to explain to Li Shimin, so he could only use a new term.

Anyway, even if Li Shimin continued to ask, he was only going to answer that it was a new craft.

However, this time Li Shimin did not continue to ask.

Although Li Shimin didn't understand it, he directly attributed it to one of the immortal arts. Now there are so many things in Li You that he doesn't understand, and he has become accustomed to it.

At that moment, Li Shimin asked what he wanted to know: "Then how long can Youer's briquettes burn?"

After feeling the feasibility of using coal for heating, Li Shimin began to care about other issues.

This time, before Li You could speak, Feng Shaoshi rushed to say: "Return to Your Majesty, one such briquette can burn for more than two hours."

"I have tried it. When I go to bed at night, I will replace it with a new coal cake. The stove will still be a little warm the next morning."

Hearing this, Li Shimin was shocked again, the staying power of this briquette is too strong.

A piece of briquette can last all night, what kind of concept is this!
