When Aaron and Alicia came to the open space behind the tavern, they found that there were already residents waiting for them.

"What are they doing around here?"

"Maybe it's to see what you are doing, young master."

"So that's where the rumors came from."

I saw the surrounding residents talking in low voices, and some residents even took out copper coins, as if they were betting. This scene made me a little embarrassed.

"Leave them alone."

Because the residents usually don’t have much entertainment, so the bad young master who loves to drink and destroy will actually build a house. This kind of thing with a great sense of contrast, I think it must be very attractive and entertaining to them.

I took the shovel and came to the frame of the house that was built yesterday. At this point the house has finished the foundation and walls, leaving only the floor heating system and the roof.

I'm going to start with the floor heating system first. First, I compared flat stones and built something like a fireplace.

Of course, to make sure it is stable and durable, I used river bottom silt as an adhesive between the stones.

This fireplace-like thing, called a hearth, burns combustibles and generates heat. Then, I'm going to skip boiling the water and direct that heat to the underfloor.

Of course, this requires plumbing. Generally, PE-X pipes are used as pipes for floor heating. However, the current world definitely does not have this kind of material that needs to be produced based on heavy industry.

So I'm going to dig out the pipes directly in the foundation and then lay the planks over the foundation.

I took a shovel and started digging from the hearth, which is similar to a fireplace, so that the smoke and heat from the hearth can only go through the pipe leading to the ground.

I then lengthened this pipe in the shape of an S, making sure the pipe was as long as possible and distributed under the floor throughout the house as much as possible.

This is done to ensure that the heat is retained throughout the house as much as possible and is used more efficiently.

At the same time, I ordered Alicia to bring some stones from the river in barrels, and asked the stones to be as flat as possible.

The reason why these stones are needed is that they want to use these stones as containers for storing heat energy. It was originally intended to use water as a storage container for heat energy, but considering that there were no suitable pipes, stones had to be used instead of water.

The story has been illicitly taken; should you find it on Amazon, report the infringement.

I laid stones over the pipes that had been dug, as a means of insulation. Then cover the top of the pipe with yellow soil again to act as a cap for the pipe. At the same time, lay stones on top of the loess.

Of course, because the stones are not uniform in size and specification, some gaps need to be filled with loess to avoid gaps in the pipes, causing hot air to escape from the gaps.

Finally, it is to find a way to flatten the ground and dry the loess on the ground so that the loess can be shaped and firmed.

The whole process requires a lot of patience and perseverance. Because there will always be some errors and defects that need to be adjusted. The biggest disadvantage in this world is that there are no convenient materials provided by modern industry, so I can only keep trying to find a suitable solution after encountering problems.

The whole process took me three days. I roughly calculated that it took me two weeks from the start of construction to now.

When I was about to stand up, I found that I had injured my lumbar spine because of bending over for too long:

"it hurts…"

Alicia, who heard my voice, quickly came to the house and helped me up:

"Master Aaron, what's the matter with you?"

"It's nothing, it's just too long to bend over"

"You should pay more attention to your physical health."

Alicia said seriously.

"Father and you, do you think I'm cheating the tavern owner? I just want to prove that you are wrong."

With that said, I pointed to the finished stove:

"Look at this, as long as you burn wood in this, the heat will go into the floor of this room, and then warm the floor of the whole room."

Hear the unmistakable pride and excitement in my voice. Alicia looks curiously at the hearth I built:

"Why doesn't this fireplace have a chimney?"

"There is no chimney because the hot air goes underground. In fact, there is a chimney, but the chimney of the fireplace is upward, and the chimney of this one is downward."

…

Construction continued, and it had to be said that more and more residents came to the tavern lot every day. The tavern owner thought that his business had become better, but he didn't realize that they just came to see our construction.

"Master Aaron doesn't look like he's digging for wine."

"Maybe he plans to build a wine cellar first, and then dig out the wine from the ground?"

"You've all been scammed by Master Aaron! He's digging up heirlooms and building that house just to attract our attention."

"Maybe it's like this! I saw with my own eyes that Master Aaron dug something in the house, and then brought stones from the river into it. Maybe he was building some kind of tunnel!"

I'm actually curious about the content of the residents' conversations. However, whenever Alicia and I approached them, they ran away, as if they were worried about their secret being discovered...but the more they behaved like this, the more curious I became.

"Forget it, it's fine for them to do this, just treat it as a free publicity advertisement. As long as the house with floor heating is completed by then, other residents will soon know about it!"

Now, from the completion of the house, only the manufacture and erection of the roof remains.

To make a roof, you first need to make wooden boards, and then lay the wooden boards on the wooden frame of the roof of the house, and you're done.

Although it is very simple to say, consider that in actual use, there will be rain, water leakage and termites gnawing on the wooden boards. Therefore, it is necessary to bake the produced wooden boards with fire for carbonization treatment.

This carbonization treatment can ensure that the board is waterproof and will not be easily bitten by termites or other insects.

However, there is a problem now, that is, the board cannot be sawed with a saw, because the sawn board will destroy the internal texture of the board, causing the board to deteriorate easily.

Therefore, it is necessary to use an ax to chop wood to make planks. At this time, I saw Alicia who was sitting next to her, showing a sinister smile:

"Alicia, I need your help."

Seeing my smile, Alicia's body tensed up, and she asked vigilantly:

"Master Aaron, what's the matter?"

"I want you to help me chop these firewood. I can roughly see the boards of this size and specification."

Since I don't have a measuring tool on hand, I can only roughly compare the size with my hands.

"Why do you ask me to do this kind of thing. I have helped you a lot, but you don't even have a word of thanks."

Alicia's tone was full of dissatisfaction. Looking at her clenched fist, I started to get nervous. Because I was worried that she would be really angry and hit me.

"Sorry! It's me who has been focusing on the construction of the house recently, ignoring your help and your feelings."

As I said that, I immediately bent over to show my sincerity with actions. However, I forgot that my waist was injured before, so my violent movements made me hurt again:

"it hurts…"

Seeing my injury, Alicia ran over and said worriedly:

"You should pay attention to your body... After all, your physical fitness is really poor."

Damn Aaron, a young man has made his body so weak. Doing some physical work hurts.

Alicia sighed, then said helplessly:

"Okay, master, I will do it."

I showed a moved expression:

"Alicia, you know what? You are my angel."

In this regard, Alicia just responded to my sweet words with cold eyes.
