Datang romantic little landlord

Nowadays, glass is still a luxury item, and such a large-scale use is astounding.

In traditional Chinese palaces, the deeper the palace, the more problematic its lighting.

In the age without glass, the bigger the palace, the darker and damper it is.Even if the outside is exposed to the scorching sun, the palace still needs to be lit with many candles for lighting.

In addition, it is a wooden temple, and after a long time, it will inevitably emit a decaying smell.

This is one of the reasons why emperors used to build palaces.

However, the Daming Palace built by Li Wangyou did not have any of these problems.

Even Li Er, after seeing the palace of the former dynasty, was very moved by it, and wished he could move in immediately.

It's a pity that the Daming Palace project is only halfway through now.

Li Er wants to move to a new home, but he still needs to wait for a while.

After visiting several palaces in the former dynasty of the Daming Palace, all the officials and merchants were so shocked that they didn't know what to say, and their hearts were shocked.

Of course, those officials who were born in aristocratic families secretly scolded Li Wangyou as a fool and a prodigal son.

The Daming Palace of such a scale would cost a lot of money.

Even though the world knows that the king of Qin is the richest man in the world, he is either crazy or stupid to build a palace for Li Yuan and his father and son out of his own pocket.

The aristocratic family is still unclear about the construction of the Daming Palace and the expansion of Chang'an City. The royal family and various state governments have also invested in the project. They only think that the money is all from Qin Wang Li Wangyou's own pocket.

The aristocratic family mocked Li Wangyou's stupidity in their hearts, but they had nothing to say about the palace in front of them.

Everyone walked in front of the Hanyuan Hall, and Li Er was even more satisfied with the main hall of the Daming Palace.

Looking up at the high imperial steps in the center of the hall, Li Er couldn't help but be moved by it, so he simply took off his boots and stepped into the hall under Mi Tuo's service, ready to walk up the imperial steps himself to feel it up close.

The floor of Hanyuan Hall is paved with golden ceramic tiles specially fired by craftsmen Li Wangyouming. It is magnificent and expensive.

Li Er was about to move forward, when someone among the officials suddenly stood up and said to stop him: "Your Majesty, wait a moment. According to the old minister, the Daming Palace built by the King of Qin is beautiful and impeccable. But Bai Mi Yishu, but the King of Qin should not have laid floor tiles in this Hanyuan Hall. If the old minister is not mistaken, these floor tiles should be made of porcelain?"

"That's right, the prince has good eyesight." Li Wangyou smiled and nodded.

It was Taichangqing Wang Ying who stood up to speak, this old man had always disliked Li Wangyou and always wanted to make trouble for Li Wangyou.

Visiting the Daming Palace today, the old man was stunned for a moment. Even if he wanted to be a troll, he couldn't tell what was wrong, but it made him extremely uncomfortable.

At this moment, he finally discovered a mistake in Li Wangyou, so he naturally wanted to jump out and criticize him.

"Your Majesty, since King Qin also admitted that the floor of the Hanyuan Hall is paved with tiles, the old minister thought it was very inappropriate. Your Majesty, it is the twelfth lunar month of winter. How cold would it be if you stepped on it with bare feet? The Hanyuan Hall will be put into use in the future , don’t all the officials have to sit on the icy cold floor tiles to court in winter? Your Majesty, I’m afraid this is inappropriate!”

Wang Ying's words stunned Li Er and the officials, and then turned their heads to look at the hall with strange expressions, and they couldn't help nodding their heads, thinking that the old man's words were reasonable.

According to the custom of the Tang Dynasty, one must take off one's shoes and socks when entering the palace.

When going to court, all the officials knelt and sat in the hall.

Therefore, including the Taiji Palace, the floors in the palace are all made of wood.Even in winter, due to the thermal insulation of wood, even if you step on it with bare feet, you will not feel too cold.

But if it is masonry, it is different.

Li Er couldn't help frowning, and turned to look at Li Wangyou: "Ziyou, have you considered this matter?"

Although Li Er knew about the progress of the construction of Daming Palace, he was not clear about the specific details.He, the emperor, naturally wouldn't care about such trivial matters as what kind of floor to lay in the Hanyuan Hall.

Li Wangyou laughed when he heard the words: "Your Majesty, gentlemen, what's the matter, why don't you ask your majesty to find out with you..."

After Li Wangyou made a gesture of invitation to everyone, he took off his boots first, and stepped into the Hanyuan Hall barefoot.

When Li Er and the others thought about it, it was not a comfortable thing to step on the floor tiles barefoot in the cold winter months.

But Li Wangyou's expression not only did not show any uncomfortable expression, but was very comfortable and enjoyable.

"Hmph, pretending to be a ghost!" Taichangqing and Wang Ying muttered in a low voice, but she still took off her boots, ready to verify it herself, so as to refute Li Wangyou.

Including Li Er, everyone stepped into the Hanyuan Hall one after another, and the next moment, differences appeared on their faces.

Many impatient people didn't even care about the emperor's disapproval, and squatted down directly, reaching out to touch those shiny golden floor tiles.

"Daozu, why are these floor tiles hot?"

"The floor tiles are as warm as jade? What, what's going on?"

The old man Taichangqing Wang Ying was even more sluggish, and the warm touch from the soles of his feet blocked all his words.

Li Wangyou glanced at him, and the corners of his mouth slightly turned up: "My lord, how is it? The floor tiles of the main hall may satisfy the lord? If the lord still feels the coldness, then Gu can only recommend the lord to go to the Pharmacy Bureau to see Liu Fengyu." Look at the bones."

Wang Ying's old face was flushed red, but she couldn't utter a single rebuttal.

How could all the officials of the aristocratic family help at this moment? They can only be thankful that they did not follow Wang Ying to question the King of Qin before, otherwise they would be like Wang Ying now, and they would be ashamed by the King of Qin.

Li Er ignored Li Wangyou's taunting of Wang Ying, but he was seldom curious. He couldn't help but asked, "Ziyou, what kind of magic technique did you cast? Why are the floor tiles so warm in this huge Hanyuan Hall? And the inside of the main hall is also so comfortable, like spring returning to the earth?"

Li Er's words reminded everyone, only then did they notice that, apart from the fact that the floor tiles in the hall were as warm as jade, the temperature inside the hall was not as cold as outside the hall.

Everyone was wearing heavy winter clothes and furs, and they even felt hot in the hall, and wished they could take off a few more quickly.

Li Wangyou laughed, reached out and untied the thick fur on his body, and took it off.

"Your Majesty, gentlemen, there is no need to wear such heavy clothes in this hall. The temperature inside the hall is more than ten degrees higher than the outside world. Even if you don't wear winter clothes, you won't feel cold."

Ever since Li Wangyou started teaching at the Royal Academy and invented the thermometer, the concept of temperature has been understood and accepted by everyone.

Under Mi Tuo's service, Li Er also took off his heavy winter clothes, and moved his hands and feet very easily.

"Ziyou, don't be a fool, tell me quickly, why is the Hanyuan Hall so warm? I don't see any braziers in the hall, let alone smoke. How did you do it?"

In the Tang Dynasty, people kept warm in winter, mainly relying on charcoal from braziers.

It works well in a closed room, but the smell of soot is indispensable.Moreover, in a palace as big as Hanyuan Hall, no matter how many braziers there are, it will not be very warm.

But in front of the main hall of Hanyuan Hall, everyone can see clearly that there is no brazier, and there is no trace of fireworks.

Li Wangyou stomped on the floor tiles twice with his foot, and explained with a smile: "Your Majesty, at the beginning of the construction of the Hanyuan Hall, I ordered craftsmen to lay a lot of copper pipes. When winter comes, these The boiler connected by copper pipes will continuously inject hot soup. In this way, even if the outside is bitingly cold, the inside of the hall can still be as warm as spring, and there will be no smoke, which is what I call floor heating."

To put it bluntly, it is the floor heating system of later generations.

The principle is not complicated, that is, it is not a rare thing to use the thermal radiation of hot water to heat the floor and the air in the hall.

But in the Tang Dynasty, this was a remarkable "invention".
