Abandoned woman from a poor family, she is addicted to wealth

Chapter 326 Floor Heating Blueprint
[Congratulations to the host for completing the hidden task—let the scumbag get retribution, the random rewards have been distributed to the system backpack, please check the host! 】

Lu Jiu was paying homage to his lost hundred taels of gold when he suddenly heard such good news.

Lin Wenyi... died?

Qian Qian: "Yes, Lin Wenyi and Wang Yingying died together."

"Tell me specifically." Lu Jiu said with interest, "Let me be happy."

"( ) good~"

Qian Qian then told Lu Jiu the ins and outs of the whole matter.

Lu Jiu couldn't believe it, and Fu Lanqing's handwriting was among them.

Although the reason why he made the move was because Wang Yingying plotted against him.

But Fu Lanqing did help her.

It feels so wonderful to receive a box lunch without having to do it yourself!
She decided that from now on, Fu Lanqing will still be her sisters!

"Master Jiu, do you want to open a gift bag?"

Qianqian reminded as if there was nothing.

Taking advantage of the fact that Master Jiu has just embraced the son of luck, maybe he can open a good thing.

"open!"

Although Lu Jiu knew that she couldn't open anything good, maybe a roll of toilet paper, but she couldn't help being happy!

[Congratulations to the host, you have obtained a floor heating blueprint. 】

Lu Jiu: "!!!"

Oh my god, are you kidding me?
Floor... Floor heating drawings?
When did her luck become so good?
etc--

Lu Jiu thought, it can't be the modern floor heating, right?

Could it be done in ancient times?
Seemingly seeing Lu Jiu's concerns, Qian Qian patiently explained: "It's an ancient floor heating drawing~"

Lu Jiu opened the drawing and saw that it was indeed a floor heating drawing that could be realized in ancient times.

In this world, humans still rely on charcoal fires for heating, and there is no floor heating at all.

This drawing is really timely.

Although she can't sell it for a while, it can allow her family to spend the whole cold winter comfortably.

This drawing was only available hundreds of years later, and the famous Ming Palace in later generations was built with this drawing.

The walls of the palace were built into hollow "sandwich walls", commonly known as "fire walls".

A fire path is dug under the wall, and the charcoal mouth for adding fire is set under the eaves outside the hall.Burn a charcoal fire in the charcoal mouth, and the heat can warm the entire hall along the sandwiched walls.In order to make the thermal circulation smooth, there is an air hole at the end of the fire path, and the smoke is discharged from the air outlet under the platform.

Moreover, this kind of fire path also leads directly to the emperor's imperial bed and under the kang where other people sleep in the palace, forming a "warm kang" and "warm pavilion", which makes the whole palace feel as warm as spring.

The air vents of the Kang of the Ming Dynasty Palace were either opened on the side of the palace base and carved out of stone into the shape of "money eyes"; Its location is hidden and difficult to find, if it is not pointed out by insiders, it will not be easily discovered.

The palaces in the Ming Palace are all built on bases made of blue bricks or white stones.

The way to build a kang is to reserve a "coil-shaped" or "centipede-style" fire path inside the base, winding through various places underground.

When burning the kang in winter, the charcoal is ignited in advance, and then pushed to the entrance of the kang with an iron cart, and poured into the fire.

(... [-] words are omitted below.)
In this way, the heat generated by the burning of charcoal will flow underground along the fire path, gradually heating the indoor floor tiles, thereby increasing the room temperature.The advantage of the kang is that the fire chamber is set outdoors, so there is no open fire or smoke indoors, and it does not take up space. At the same time, the eunuch who is responsible for adding fire and charcoal can operate it outdoors, so as not to interfere with the activities of the indoor owner.
