Looking at Zhu Yuanzhang's surprised eyes, Hu Changan smiled slightly, and said calmly: "Your Majesty, the reason why you didn't feel warm when you burned so much charcoal in the palace before was because the charcoal would dissipate heat while heating. ”

"The palace is big and windy, and the charcoal only emits a little heat, and it is all blown away by the cold wind, so naturally people will not feel much heat."

"And the conservatory I built built was a sandwich wall and moved the stove into the wall."

"On the outside of the wall, I used a more insulating material so that the heat didn't escape."

"On the inside, I chose a material that can dissipate heat, so that the heat contained in the sandwich wall can be well diffused into the room."

"If Your Majesty doesn't believe me, you can touch this wall."

Zhu Yuanzhang listened to it, and he also touched it curiously.

Sure enough, as Hu Changan said, the outer surface of this wall is cold, but the inner surface of the wall is a little hot with high temperature.

Seeing this, Zhu Yuanzhang couldn't help but be happy.

That's a pretty good thing!

With this greenhouse, he will no longer have to be frozen in winter!

And the cost of this greenhouse is not much.

If you use a conservatory, then this winter, you will definitely save a lot of money in the palace!

The more Zhu Yuanzhang looked at this conservatory, the more he liked it, and couldn't help but say to Zhu Biao: "Biao'er, I look at the conservatory, it's really good." On the other side of your East Palace, do you want to build a conservatory as well? ”

"Erchen is also about to talk about this." After hearing this, Zhu Biao also replied with a smile, "It's still too late, I think this kind of greenhouse can be built in the entire Forbidden City." ”

"Anyway, there is still a lot of vacant land in the Forbidden City, and it is enough to build a few conservatories."

Seeing this, Zhu Yuanzhang also waved his hand and happily agreed with Zhu Biao's idea.

Zhu Yuanzhang is still willing to pay this money.

Not only can you improve the quality of life, but you can also leave a large amount of heating bills in the future, so why not.

After Zhu Yuanzhang gave the order, Zhu Biao said to Zhu Yuanzhang with a smile: "Father, there are surprises waiting for you in this house?" ”

"Oh, and surprises? I wonder what kind of surprise it is? Zhu Yuanzhang looked at Zhu Biao with interest.

Zhu Biao smiled and pushed Hu Changan out: "Father, there are some things that I don't know much about, so I'll let Hu Aiqing introduce them to you." ”

"Yes, no problem." Zhu Yuanzhang is also as good as a streamer.

He was already satisfied enough with this conservatory.

Zhu Yuanzhang is curious, what kind of surprises will be waiting for him next?

Seeing this, Hu Changan also smiled slightly, and said to Zhu Yuanzhang: "Your Majesty, I will introduce you to this barbecue and hot pot next." ”

In the greenhouse, Hu Changan also specially served barbecue and hot pot for Zhu Yuanzhang.

In this way, Zhu Yuanzhang can enjoy delicious food without leaving home in the cold winter.

Hu Changan took Zhu Yuanzhang and Zhu Biao to a platform, pointed to the platform and said to Zhu Yuanzhang: "Your Majesty, this is the barbecue table I prepared for you, on which you can bake all kinds of dried fruits." ”

What Hu Changan pointed out to Zhu Yuanzhang was a round platform with a strange shape.

Unlike the usual round platform, in the center of this round platform, barbed wire was hollowed out.

Zhu Yuanzhang looked at this strange-shaped round platform, and he was also a little puzzled.

I don't know how to use this thing?

As if seeing Zhu Yuanzhang's doubts, Hu Changan smiled slightly, opened the barbed wire in the center of the round platform, put a few pieces of smokeless charcoal in it, lit it and closed the lid again.

"Your Majesty, this is actually a simple oven, as long as you put charcoal in it, you can bake things on it."

Zhu Yuanzhang studied the structure of the furnace for a while, and nodded slightly.

Although Zhu Yuanzhang can't study this thing by himself, Zhu Yuanzhang can still understand this basic structure.

It's nothing more than moving the stove inside the round table.

However, Zhu Yuanzhang raised his doubts: "Hu Aiqing, if you burn like this, won't you worry about a fire?" ”

It's no wonder that Zhu Yuanzhang attaches so much importance to the fire.

In ancient times, because the buildings were made of wood, it was a terrible thing to have a fire.

All kinds of houses are not burned one by one, but in patches.

The loss in this is absolutely indescribable.

So in the palace, it is common to see some heavy large water tanks placed on both sides of the road.

These water tanks are all designed to prevent fires from burning in the palace.

As long as there is a fire, the palace people can scoop water in the large tank on the side of the road to extinguish the fire, which is very convenient.

Seeing Hu Changan put the stove in the room, Zhu Yuanzhang's first worry was the fire.

When Hu Changan heard this, he also smiled slightly and said, "Your Majesty doesn't need to worry. I use charcoal here, and there is no open flame for charcoal burning, so when burning, there will be absolutely no sparks splashing. ”

"Besides, Your Majesty, my furnace is built high, and the inner walls of this furnace are made of fine iron."

"Even a few small sparks can't get over the stove and splash on the table."

"Besides, there are defenses in my house!"

Hu Changan said as he opened an inconspicuous small jar next to him and said: "This is filled with emergency water, once there is a fire splashing, as long as you hold the jar and pour it, you can quickly extinguish the fire." ”

Of course, Hu Changan put a jar of water here, not just to extinguish the fire.

After all, the greenhouse is relatively dry, and people are afraid that they will feel unwell if they stay for a long time.

Putting a jar of water here can also play a role in artificial humidification.

Seeing this, Zhu Yuanzhang also sighed.

I didn't expect this Hu Changan to even take this kind of thing into account.

This Hu Chang'an is really a talent!

At the moment when Hu Changan and Zhu Yuanzhang were talking, the stove was almost burning.

Hu Changan saw that the stove was almost hot, so he took out some corn and peanuts from the basket on the side and put them on the stove.

These corn and peanuts were also exchanged by Hu Changan from the system.

Although corn and peanuts have become known to everyone in modern times, they have not yet been introduced to the Central Plains during the Hongwu period.

It was not until the end of the Ming Dynasty that corn and peanuts would bloom and sprout on the land of China.

Even during the Qianlong period of the Qing Dynasty, peanuts were a precious dish at royal banquets.

Zhu Yuanzhang saw that Hu Changan took out these many strange things from the basket, and he couldn't help but be confused by the second monk.

Didn't you say that you want to bake something to eat, why did Hu Changan turn his head and take out such a strange thing?

These things look so strange, can they really be eaten?
