Chapter 1067

After making an invitation gesture to the crowd, Li forgot to worry, took the lead in taking off his boots and stepped barefoot into the Hanyuan hall.

Li Er and others thought it was not comfortable to step on the floor tiles barefoot in the cold winter.

But Li's expression not only didn't have any uncomfortable expression, but was very comfortable.

"Hum, playing tricks!" Taichang Qing Wang Ying whispered, but still took off her boots and prepared to verify it in person, so as to refute Li forgetful worry.

Everyone, including Li Er, stepped into the Hanyuan hall. The next moment, everyone showed a different color on their faces.

Many impatient people even squatted down and reached out to touch the glittering floor tiles.

"Why are these floor tiles hot when Daozu is on the top?"

"This floor tile is as warm as jade? What's going on?"

The old man, taichangqing Wang Ying, was even more dull. The warm touch from the soles of his feet blocked all his words back.

Li forgot to worry, glanced at him and turned his mouth slightly: "how about the prince? The floor tiles of the main hall may satisfy the prince? If the prince still feels cold and biting, he can only recommend the prince to go to the Shangyao bureau to find Liu Fengyu to have a look at his bones."

Wang Ying's old face turned red, but she couldn't say a word of refutation.

At the moment, many aristocratic family officials can't help but rejoice that they didn't speak with Wang Ying to question the king of Qin. Otherwise, they must be like Wang Ying and be hated by the king of Qin.

Li Er also ignored Li forgetful worry's ridicule of Wang Ying, but he was rarely curious. He couldn't help asking, "Ziyou, What immortal Dharma have you applied? Why are the floor tiles so warm in this big Hanyuan hall, and the hall is so comfortable, like spring returns to the earth?"

Li Er's words reminded the public that except that the floor tiles in the hall were as warm as jade, the temperature in the hall was not as cold as outside the hall.

They were wearing heavy winter clothes and furs. They even felt hot in the hall. They wanted to take off a few pieces to be light.

Li forgot to worry and smiled. He stretched out his hand to untie his thick fur and took it off.

"Your Majesty, gentlemen, you don't need to wear such heavy clothes in the hall. The temperature in the hall is more than ten degrees higher than the outside world. Even if you don't wear winter clothes, you don't feel cold."

Since Li began teaching at the Royal College and created a thermometer, the concept of temperature has been understood and accepted by everyone.

Under the service of Mituo, Li Er also took off his heavy winter clothes and moved his hands and feet easily.

"Ziyou, don't sell off. Tell me quickly why Hanyuan hall is so warm. I don't think there is a brazier in the hall, and there is no smoke-free fire. How did you do it?"

In the Tang Dynasty, charcoal was mainly used for heating in winter.

The effect is good in a closed room, but the smell of medium smoke is indispensable. Moreover, a palace as big as Hanyuan hall can't be warm even if there are more braziers.

But in front of the Hanyuan hall, everyone saw very clearly that there was no brazier or a trace of smoke and anger.

Li Qieyou stamped on the floor tiles with his feet, smiled and explained: "Your Majesty, at the beginning of the construction of the underground of Hanyuan hall, the minister ordered craftsmen to lay a lot of copper pipes. In the winter, the boilers connected with these copper pipes will be continuously injected with hot soup. In this way, even if the outside wind is biting, the hall can be as warm as spring, and there will be no smoke and fire. The minister calls it floor heating."

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

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

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

After listening to Li's explanation, including Li Er, everyone squatted down and felt the ground temperature with their hands. Li forgot to worry about the appearance of a curious baby.

"Your Majesty, not only the Hanyuan hall is paved with floor heating, including several main halls in the previous dynasty and the future harem bedroom hall. The ministers have arranged floor heating to ensure that your majesty will not be disturbed by the severe cold in winter."

"Good! Good! Ha ha, I'm looking forward to the early completion of the Daming Palace so that I can move into the new palace with the supreme emperor and the empress." after spending a long time in the warm Hanyuan palace, Li Er didn't want to go out again.

Li Er turned his eyes again and silently made a color to Li Er to remind him not to forget today's business.

He, the emperor of the Tang Dynasty, wants to stay in Daming Palace as soon as possible. It depends on whether today's plan can succeed.

Li Qieyou and Li Er invited all the officials of the court hall, as well as the merchants, rich merchants and Persian Hu merchants in Chang'an city to Daming Palace today, not to show off, but to "make money".

To put it bluntly, including Li forget worry and Li Er, and the leaders who have taken shares in the country. Now they have no money

To expand half of Chang'an City and the Daming Palace of Nuo Da, even if Li forgets to worry about "cutting corners on work and materials" again and again, it will cost a lot.

The cost of expanding the wall of Chang'an City alone is unknown, not to mention the previous dynasty when the Daming Palace was built.

If you want to continue to build the back palace of Daming Palace, I'm sorry, the landlord has no surplus food.

He and Li Er today called people to visit the former dynasty of Daming Palace. In the final analysis, it was to "sell the house" to recover the funds.

Li Er understood Li's hint of forgetting to worry. He blushed, but he coughed and asked: "Ziyou, you really deserve to be a disciple of the Taoist ancestors in the world. I am very satisfied with the Daming Palace. However, on that day, you promised me and all officials not only to build the Daming Palace, but also to expand half of Chang'an City, but I don't know how the new town in the north of the city is expanding now?"

With Li Er's words, Fang Xuanling stood up: "What your majesty said is very true! I admire the Daming Palace after I have visited it. Ziyou, but I don't know if I can sell a residence with you after the expansion of the north of the city? Now my residence is next to the Tai Chi palace. It's humid in summer and cold in winter. It's really not a suitable place to live. Since your majesty wants to move to the Daming Palace in the future, I also want to move to the new city to be a companion with your majesty."

Fang Xuanling's words made everyone move in their hearts.

But as he said, even Li Er felt that Taiji palace was not livable, not to mention these court officials and rich businessmen.

But they had no choice but to live in the Lifang near the Taiji palace in the north of the city. After all, it is not only a symbol of identity, but also an embodiment of status.

If Li Er moved to the Daming Palace in the new town in the north of the city in the future, they would still live in the original Lifang, which would be a little different.

If you move to the new city in the north of the city with higher terrain, it would be better.

Li Qieyou secretly raised his thumb. Sure enough, they are all old opera bones. There is really nothing to say about this acting skill!

If Datang has an Oscar, including Li Er, it should be awarded the film emperor Xiaojin man!

After the two "fangtuo" spoke, Li forgot to worry immediately and said with a smile: "Your Majesty, Fanggong, now the Waiguo city of Chengbei new town has been built, and the roads and square walls in the city have been built. If Fanggong is interested in moving to the new town, there will naturally be no problem. However, in the new town, my nephew doesn't sell land, but directly sells his residence. I wonder if Fanggong is interested?"

"Oh? What does that mean? Let's listen to Ziyou." Fang Xuanling asked with a smile.

Datang does not have a "real estate business", but in addition to buying "second-hand" old houses, it usually recruits craftsmen to build mansions after purchasing land.

Li forgot to worry that he didn't sell land, but directly sold the residence, which also aroused everyone's curiosity. They all stretched their ears and wanted to hear how he explained
