She didn't even need to say anything. As soon as Sheng Nanxi approached the courtyard, she felt the temperature around her rise by several degrees, and the air was filled with the lingering smell of rotten eggs.

In fact, this is a natural phenomenon. Natural hot spring water is rich in hydrogen sulfide and other minerals. The higher the temperature, the higher the hydrogen sulfide content, and the stronger the odor.

But she wanted to use natural geothermal resources to build floor heating and live a life of ease in her hometown. How could she give up her ambitions just because of a little odor?

The little kid immediately pretended to be very sensible and waved to his grandmother:

"Grandma, I'm not afraid. Daddy said that reading ten thousand books is not as good as traveling ten thousand miles. What he meant was that in addition to learning knowledge from books, children should also see more of the world to broaden their horizons."

"I've never seen such a smelly hot spring, so I must go in and take a look. As long as I learn something, I won't be afraid of any hardship or fatigue!"

This little girl is used to judging people by their appearance. When she meets unreasonable people, she will suppress them with thunder and lightning. When she meets people who really care about her, she will not hesitate to spend some time to persuade them and promote their relationship.

As expected, when she said this, the old ladies' confidants were all melted. They all thought that since the young lady was so sensible, there was no reason for them not to be safe. Even if they were suffocated, they had to accompany the young lady to study the well inside.

Gu Cheng, who was standing aside, raised the corner of his mouth with a faint smile and watched carefully as the little girl fooled people.

When all the grandmothers were completely fascinated by her, they took out a handkerchief scented with agarwood from their bosoms to cover her mouth and nose.

Then he turned to the servants and said, "If any of you are not used to the foul air, you can just wait. She is just a child, she wants to go in and find out everything."

"Since the old lady and the old man have said that they treat us as their own family, there is no need to be so polite."

One of the two children was honest and the other was considerate of the servants. They were masters at winning people's hearts. The servants were shocked to hear how flattered they were.

Even the servants who had previously ignored the two children because of their young age changed their expressions. They followed the crowd diligently and surrounded the two of them as they walked in.

Oh my god, how could they have thought that these two kids were being unreasonable and pretending to know what they were doing?

Such a sensible and considerate child is obviously born with great wisdom, how could he be a wicked and willful person? !

It turned out that they were short-sighted. Sanniang had been clever and likable since she was a child, and Sanguye was also a well-known figure. The child born from her should be a dragon among men. How could they be compared with these mud-legged children?

This changed everyone's attitude, and no one questioned the two children's decision. The young lady could study whatever she wanted and visit wherever she wanted.

Some people even saw that she really didn't understand the truth and actually discussed serious matters with Sheng Nanxi.

"Miss, are you interested in the North Fourth Courtyard? This courtyard has a good feng shui and is fully equipped. There is a hot spring in the courtyard, which is warmer than other courtyards."

"This year's climate is much colder than previous years. Half a month ago, the second wife said that the weather was so cold that she wanted to move to the North Fourth Courtyard to live permanently. Unfortunately, the smell of the spring water is so strong that no matter how much incense is burned, it can't be completely dispelled. The second wife moved back after living there for only a few days."

"If you like this courtyard, you have to think about how to get rid of the stench that fills the house."

Sheng Nanxi thought of her second aunt who had a sullen face at the banquet the other day. She didn't expect that this person was such an action-oriented person.

It seems that her behavior at the banquet was not because she was always aloof, but because something had simply upset the other party.

But she didn't mind other people's business, so she pretended to go forward to check the water quality, took out a thermometer and dipped it into the spring water.

After a few minutes, I took it out and saw that it was 72 degrees Celsius!

Great! It's really easy to find it after searching everywhere!

The temperature of this hot spring is too high, which is indeed inconvenient for the ancients. But she wants to lay a large area of ​​floor heating covering several courtyards, so this water temperature is perfect.

The hydrogen sulfide content in the hot spring is too high, and it is indeed harmful to health if people stay near it for a long time. But she is not without a way to solve this small problem.

The little girl made up her mind and immediately sent someone to inform her grandmother that her family wanted to stay in a few neighboring courtyards in North Fourth Street.

The Sheng family naturally did not object to her decision, but the Li family did not know how capable this little girl was. They did not expect that she would just point at the least suitable place to live, the North Fourth Courtyard, and they all advised them to take another look.

The Sheng family was determined to listen to Xiao Xier. The Li family tried to persuade them to no avail, so they had to ask the maid to clean up the North Fourth Courtyard and give it to them temporarily.

Fortunately, the temperature in winter is low, and the water vapor does not evaporate as quickly as in summer, so the smell in the yard is not as pungent as in summer.

The servants were constantly helping the Sheng family to clean up the yard, while Sheng Nanxi was running around the yard in a hurry on her short legs.

Others saw her as a little baby who had just moved into the new courtyard and were a little too excited. When passing by, they reminded her to be careful not to fall. In fact, her sister Xi had already used the soil system to explore the soil of several nearby courtyards and had a preliminary plan for laying floor heating in her mind.

After all, this mansion is their ancestral home, and their family cannot live here for a long time. At most, they can live here for a few months, survive the severe cold years, and then find a piece of land to build their own house.

Therefore, these courtyards do not require large-scale renovation. They only need to drain the hot spring water and install simple floor heating devices in the houses.

After these courtyards are paved, they will try to install floor heating in other courtyards. In this way, their ancestors and their family can spend this winter smoothly.

When the weather warmed up in the spring, she and her family began to prepare to build a new home, a large-scale greenhouse plantation and other facilities. Even if the winters in the next few years were extremely cold, they would surely survive them safely.

It stands to reason that modern technology is advanced enough that humans can directly use geothermal energy to generate electricity and heat.

But for Sheng Nanxi at this stage, generating electricity is too troublesome. After much consideration, she decided to adopt the traditional method, using the height difference to drain the spring water, and then use a manual valve to adjust the water flow speed and switch.

The spring water here is hot and corrosive, so the selection of pipes is naturally very particular.

After a long period of selection, Sheng Nancy finally chose PPR pipes, which are corrosion-resistant and can be mass-produced using 3D printers in space.

There are also assessments of house thermal insulation, overall plans for pipe laying, and the location and distribution of manifolds and manifolds...

They are all profound subjects.

Although many design sketches can allow Zhaocai, the AI ​​butler, to achieve success with one click, she also needs to master a lot of basic common sense as a practitioner.

Fortunately, the speed of time in Sheng Nanxi's space can be adjusted automatically. She immersed herself in the space and studied relevant knowledge day and night. After she had learned most of the basic theories, she returned to reality in just a blink of an eye.

These past few days, everyone in the Sheng family has been busy, and each one of them has been commanded by her.

One moment he said he wanted to build a small ventilation tower to exhaust the large amount of steam coming out of the spring, the next moment he threw out a design drawing and asked the fifth brother to organize the secret guards to build a canal next to the spring, and the next moment he asked people to remove all the floor tiles in several main houses, saying that he wanted to renovate them...

Of course, these are just superficial things done for show.

She mastered the earth and metal elements, and with Zhaocai's help, installing floor heating was a piece of cake for her.

Whenever there was a gap between two groups of people changing shifts, Sheng Nanxi would directly use the earth-related magic to extend and reinforce the canal they had just built. The ventilation tower was also automatically built under her control, speeding up the progress by several days in a blink of an eye.

As for the installation of floor heating in the house, she used her mind to directly lay the insulation boards and reflective film on the pipes, backfilled the soil with the earth system and tamped it, and instantly sealed the soil layer with the wind system. Finally, she used her mind to control the laying of floor tiles.

Without using electricity, it would take more than half a month to install floor heating in the houses in the two courtyards even in modern times. However, Sheng Nanxi directly used the four-series infrared heating system and completed the installation in less than six days.

Of course, the price was heavy. The chubby girl worked all night for several days in a row, and when the work was finished, she was so tired that she fell asleep immediately, not caring about what was delivered to her.

The weather was just as described in the book. After clearing up for a few days, it started snowing heavily again.

On New Year’s Eve, lights and ribbons are hung everywhere.

Li Zhenyi and Sheng Jinghai took their three sons to the main hall early in the morning to pay their respects to their grandparents. Because it was too early, no one had the heart to see Sheng Nanxi who was still sleeping.

This somehow caused bad luck to some people. As soon as Li Zhenyi stepped into the main courtyard, she heard the strange voice of her second sister-in-law:

"But the third sister is here? Why doesn't your little Xier come to wish the old lady a happy new year?"

"Hey - don't think my second sister-in-law is too nosy. I just asked her one more question because I haven't seen her for a few days. After all, you guys have been knocking and banging behind closed doors all day, and we don't know what you are doing..."
