Older people fear the most is winter, and this cold air is also very likely to cause many diseases.

But now...

Li Yuan then stepped on the floor with his feet together.

This warmth began to spread throughout my body along my legs and feet.

It seems to moisten things silently, without that strong feeling, but it is a coincidence that the body feels extremely comfortable.

It gradually began to feel a little hot.

Li Yuan was wearing three layers of inner and outer layers of outer layers, but at this moment... he couldn't help but take off his coat, and still felt fine beads of sweat oozing out from his forehead.

"Huh?" Li Yuan suddenly said, "What's this called?"

"Call...Call..." Liu Wu thought for a long time: "What is the floor heating?"

Li Yuan said: "It's really warm, very comfortable, much more comfortable than charcoal fire. I feel sick when I smell the charcoal fire. When I get close, I feel hot, and when I get far, I feel that the heating is not enough. This thing... is quite interesting, just like the weather is getting warm and spring is getting hot."

Liu Wu: “…”

In fact, Liu Wu began to feel hot too.

"Come on, give me a generous dress. I have worn too much clothes and it's hot."

"Oh, oh." Liu Wu hurriedly gave Li Yuan a loose clothes.

After working hard, I was wearing only one inner jacket. In the middle of winter, I stepped on the floor, as if I had taken off the burden of pounding, and I felt that I was getting loose.

Li Yuan said, "You have to go and ask, what's going on, don't ask around, go quickly."

Liu Wu dared not neglect.

Actually, he wanted to ask clearly.

However, most of the people in this palace are wary of the people in the Hongyi Palace, and there is a gap between them. Everyone is unwilling to talk too much to the people in the Hongyi Palace.

Even if Li Shimin repeatedly expressed his filial piety to the Supreme Emperor, the people in the deep palace were inevitably accustomed to intrigue and were wary of being afraid that he would say too much to the people in the Hongyi Palace and be taken into account.

Liu Wu hurried away, and this time he planned to ask carefully.

So I waited for a long time before I came back.

As soon as he entered the bedroom, he began to take off his clothes and then found the leisurely Li Yuan. At this time, a concubine was serving tea to Li Yuan with her jade hands.

Li Yuan looked at the beauty's neck with a smile, stretched out his hand, and wanted to touch it. The beauty was shy and subconsciously shrank, Li Yuan shook his shriveled lips and said, "I will be angry if I don't let me touch it."

But when I saw Liu Wu coming back.

Li Yuan then raised his face and waved his hand to let the beauty retreat.

Liu Wu bowed and said, "The Supreme Emperor, I have inquired about it and said it was a heating furnace made by the Chen family. This heating furnace is hundreds of feet away. Outside the palace, they burned water there and conducted heat in along the pipe."

Only then did Li Yuan realize that it was just a false alarm. He sighed: "If I had known, I would let you find out clearly."

Liu Wu said: "It's a slave who deserves to die."

Liu Wu continued, "I heard that this thing is very expensive, so Chen Zhengtai and the prince personally entered the palace to install it, and they put a lot of effort. The first one... was to spread the pipes to Hongyi Palace. I heard that... just installing it will cost tens of thousands of guan, and you also need to hire people and burn coal. After all, you will need at least a thousand guan every year."

When Li Yuan heard this, he shuddered: "So expensive?"

Tens of thousands of coins are definitely not a small amount of money for the royal family.

And it was made by the prince and Chen Zhengtai himself.

Not to mention, the first one is to come to Hongyi Palace first.

What does this mean?

Li Yuan's face suddenly turned rosy: "Well, very good, very good, the prince is still filial, Chen Zhengtai... He is the descendant of Chen Jiye, Chen Jiye is an honest man. His son is not too bad. A tiger father has no dog son, very good, very good..."

What he was even more pleased was that...it was most likely Li Erlang's arrangement to lay out Hongyi Palace first.

If this is the case...then... it means Erlang is not crazy yet, and he can temporarily put down his guard and continue to live his life.

Liu Wu smiled and said, "Yes, they all pretend to be the Supreme Emperor in their hearts."

"Haha..." Li Yuan's eyebrows were dancing: "You come and help me draw an edict. This is tens of thousands of chunks of coins, not a decimal. I have to praise Chen Zhengtai."

Liu Wu was surprised. You must know... Although Li Yuan was the Supreme Emperor, in order to show that he had no care about the matter outside, he had never drafted an edict in the past three or four years. Now he suddenly had to draft an edict, this... this...

Li Yuan narrowed his eyes and said, "This is the arrangement of Erlang and the prince. They both made efforts and spent so much money. This edict is to praise this boy from the Chen family, but at the same time, it is actually to hint to others that I have inherited the filial piety of Erlang and the prince. Therefore, this edict must be drafted immediately, and Erlang will understand what I mean."

Liu Wu didn't dare to neglect: "I'll do it now."

Seeing Liu Wu leaving, Li Yuan called a small eunuch and ordered: "Go, I am happy today. Prepare some good wine, and call Zhou Meiren, Wu Meiren, Zhang Meiren, Yang Meiren, Zheng Meiren and others."

"promise."

Chen Zhengtai was busy sweating profusely at this time. The experiment was quite successful, but it was finally not wasted.

Next... we need branch pipelines to introduce Ziwei Palace and Lizheng Palace.

Even Chen Zhengtai thought about where Princess Sui'an's mother was, and she led her one by one!

This is my own person. Even if someone in the palace is gossiping, Chen Zhengtai is not afraid. What if I have the ability to pay the money, you can pay it yourself.

So he called Princess Sui'an, and then carefully modified the engineering drawings. After a long time of struggle, he increased the budget of several thousand chunks.

In fact, this is the case with this thing. The initial investment is large, but the cost in the later stage is getting lower and lower.

Princess Sui'an looked very worried: "There is no one in the bedroom of Concubine Wei and others."

Chen Zhengtai said with confidence: "If the Wei family has money, pretend by themselves. If you can't afford it, don't pretend. Where can you both want to show off and not be willing to give up money? I am filial to your mother. If they are jealous, let them be jealous."

Princess Sui'an said something bad, and kept shaking her head, but she felt happy in her heart. Finally, she nodded helplessly: "Okay, okay, I'll listen to you, I have to go and say something to my mother."

She went there excitedly with a smile like a butterfly.
