However, Lin Ying naturally didn't want to miss out on the natural advantage of hot spring water, so, as she had planned before, she first installed the water pipes in her house. She had already decided that each room should have its own bathroom, so when the house was built, recesses were dug underneath each room.

While the children were asleep, Lin Ying got to work. First, she laid out the drainage pipes. Starting from Lin Ying's room, the pipes went downhill to the drain at the front door. Then she backfilled the drain with soil. Lin Ying then went back to sleep.

The next day, she began building a bathtub and a squat toilet.

Lin Ying's belly is quite big now, making these chores inconvenient for her. She'd like to buy ready-made ones, but she can't explain it clearly.

So, she could only prepare the materials, then sit on a small stool and work there. After a while, when she ran out of materials, she would get up and make more.

Just as Lin Ying was about to get up, she saw Hao Yu carrying the mortar piece by piece to her. The mortar was too heavy for him to handle, so he used a small shovel to move it little by little.

Lin Ying couldn't help but smile and said, "Little one, don't do these chores so early. If you don't study hard, you'll have plenty of time to do them later. Go watch over your younger siblings. Be careful Er Ya doesn't fall into the water."

Haoyu didn't want to go: "But, you..."

Lin Ying said, "Go ahead, go ahead. If it takes one day, it can be done in two. There's no rush. I'll take my time. I'll be more worried if something happens to Er Ya."

Haoyu nodded: "Then don't tire yourself out."

Lin Ying couldn't help but laugh out loud: "Don't always act so old-fashioned, you're only six years old! Go on, go on."

In fact, Lin Ying was much more relaxed without Haoyu around. She could prepare a lot of materials at once and store them in her space, then just take them out when she needed them.

Moreover, without that little supervisor around, her work became much easier. For example, when building the pool, she could simply place the faucet directly at its position. The same went for the bathroom; she planned to install a squat toilet, so a funnel was naturally essential.

These will all be hidden away, but they are all very useful items. Also, she plans to install water pipes directly above the squat toilets this time. That way, she can flush immediately after using the toilet.

In addition, a sink faucet is needed. Underfloor heating should also be installed at this time.

Lin Ying's house is too big. If there are fire pits everywhere, each room would need to have its own fire, which would be too troublesome and would also make it impossible to maintain a constant temperature.

Lin Ying had seen the hot spring water; when it flowed to their house, the temperature was around 40 degrees Celsius. Moreover, on snowy days, the colder the weather, the higher the temperature.

Therefore, Lin Ying decided to install water heating.

Overall, upon entering the bathroom, there's a sink directly opposite. Between the sink and the bathtub, there's a wall that's been converted into a wardrobe for storing toiletries and clothes. A wardrobe will be placed to the west of the sink.

In other words, the toilet and shower take up half the space, while the washbasin and dressing room take up the other half. This achieves both wet and dry separation and prevents odors from escaping from the toilet.

It used to take Lin Ying three days to finish a house, but after she got the hang of it, she could finish it in two days.

Finally, after half a month, the drainage and water supply pipes in the room were completely installed.

Next came the matter of getting water.

Lin Ying's house is the last house in the mountains. From Lin Ying's house, the terrain becomes steeper. Villagers usually go up the mountain by going west or east on the slope.

That's why Lin Ying's family built stone walls when they built their house.

Even the back wall of her house was made entirely of stone and cement.

Since it was the last house, Lin Ying naturally didn't need to worry about blocking the way when she went out. She simply installed a waterwheel at her doorstep, and the waterwheel's rotation would deliver water directly into a huge container for Lin Ying.

To ensure water is delivered smoothly to the house and to maintain water pressure, the container needs to be placed at a higher position and securely fixed.

Fortunately, Lin Ying was strong, so doing these things wasn't too difficult for her.

There is an overflow hole at the top of the container, so if there is too much water in the container, it will overflow and not splash everywhere.

There was a water pipe connection port at the bottom of the container. After Lin Ying finished setting these up, she installed the water truck.

Cover any exposed pipes to prevent them from freezing and cracking. There's a branch pipe specifically for underfloor heating; the underfloor heating water outlet is separate and flows back into the pool, preventing it from entering the seepage tank. Otherwise, the seepage tank would be under pressure from the daily flow.

Each room has its own independent underfloor heating connection. This ensures that the temperature in each room is comfortable.

After the waterways are completed, the electrical circuits will follow.

Lin Ying's meticulously designed waterwheel is unique, its distinctive feature being the ingenious placement of a generator in the center. As the water rushes down, impacting the waterwheel's blades, the waterwheel slowly begins to rotate. This rotation drives the central generator, gradually converting the water's kinetic energy into electrical energy.

The electricity will enter a constant-voltage motor, so the output voltage will be 220V.

Of course, for safety, circuit breakers are essential. Each room has its own independent circuit breaker, which can trip the circuit breaker directly in case of an incident to ensure the safety of personnel.

The wiring was simpler than bricklaying, but it still took Lin Ying five days.

With the plumbing and electrical work done, the next step is to lay the flooring.

Lin Ying still opted for solid wood flooring, with the wood sitting there. However, she ultimately chose to buy ready-made flooring online because she was pregnant and it was best to avoid using paint-based products.

The entire house renovation took Lin Ying about a month. She didn't even stop during the Chinese New Year.

Finally, in March, with the room heated by the central heating, it was finally habitable.

Of course, the children are too young now, so Lin Ying and Er Ya sleep in their own room, while Hao Yu and Shuan Zi sleep in Er Ya's room.

All the furniture in the house can be moved back to the room smoothly.

On that same day, Lin Ying's pregnancy began.

However, since everything had already been arranged, Lin Ying asked Haoyu to teach Aunt Chun next door, and soon, several women arrived at Lin Ying's house.

Lin Ying is a doctor herself; she can check the baby's position and also take care of her own body. In addition, the space also has spiritual spring water, ginseng pills, and other life-saving pills prepared.

Aside from the pain, she really wasn't worried about anything else.

After all, her pain was too intense.

Perhaps because Lin Ying had been exercising regularly, or perhaps because she had been nourished by the spiritual spring water, the child was born without causing Lin Ying much pain.

Because I was controlling my weight, the baby weighed just over six pounds at birth. As expected, it was a boy, just like the previous pulse diagnosis.

From that day on, Lin Ying began her postpartum confinement. Since her baby was too young, Lin Ying asked Aunt Chun to take care of her. She didn't need to take care of anything else, just help with cooking.

She can take care of the child herself.
