The little one's purse connects the two worlds, turning a desolate village into a paradise.

After carefully reading through all the requirements written on the paper, Zhao Junchen had a clear understanding of the situation.

These things are not only trivial but also a bit troublesome.

We need to think this over carefully.

He reached out and took Ya Ya's hand, leading the little one to a chair and gently instructing her, "Ya Ya, sit quietly and wait a while. I have some important business to attend to."

After settling the children in, he didn't stand on ceremony. He went straight to the car, grabbed a folding stool that his dad used for fishing, leaned it against the wall, plopped down on it, and took out his phone to contact the building materials and equipment suppliers he knew one by one.

The building materials market here is only so big, and it's always the same suppliers coming and going.

Zhao Junchen knows them all, at least most of them are acquaintances.

After some back-and-forth communication and clarifying the order of priority, it took about half an hour to finally finalize the purchase list.

Electricity is definitely the first thing to solve. After the system is built, the wiring should be installed first, as this is the foundation.

Let's start by setting up a small photovoltaic power generation system.

It just so happens that he has a senior who inherited the family business, which is off-grid photovoltaic power generation. It can provide a one-stop solution for power generation, power consumption, and power storage. In just two years, the senior has also expanded a lot of export orders.

His father was lecturing him just two days ago, telling him to learn from others and see when he could sell the sand from their Zhao family's sand quarry abroad.

Zhao Junchen: ...

Isn't this putting him in a difficult position?

After briefly explaining to his senior about what he knew about Lotus Village, the two discussed it for a while and finally finalized the configuration.

Twelve double-glass, double-sided, Class A photovoltaic panels, paired with a 6.2kW inverter/controller unit, can generate approximately 30 kilowatt-hours of electricity per day.

Add a set of 16 kWh lithium iron phosphate energy storage batteries, and store any unused electricity during the day into the batteries for normal use at night.

The hot-dip galvanized bracket, dedicated cables, and various supporting accessories were also included. The total price of the entire set of equipment was 15,800 yuan.

If air conditioning is needed, these twenty or so households probably won't be enough. However, Zhao Junchen specifically asked about it, and Ya Ya said she had no idea what air conditioning was.

Well, obviously they don't need air conditioning.

Comparing the list of appliances provided by Mr. Fang, the overall power consumption is relatively low, and this photovoltaic power supply system is fully capable of meeting daily needs.

After settling the power generation equipment, Zhao Junchen's gaze fell on the only remaining outdoor three-in-one bathroom in the house.

The water heater in this bathroom is a regular electric water heater, but it's obvious that Grandpa Fang prefers solar water heaters. Why not spend a little more money to upgrade to an integrated solar water heater with built-in electric auxiliary heating?

He raised his hand and wearily rubbed his temples.

This order was quite large, but it took a lot of effort.

The key issue is that he didn't go to see the actual site, and communication still had to rely on Ya Ya, the little messenger, to relay messages back and forth.

He wanted to call Ya Ya's elders directly to communicate, but the little girl said that she was the only one with a cell phone in their entire village.

Zhao Junchen: (╯°口°)╯︵ ┻━┻

"Ya Ya, your village doesn't even have running water?" Zhao Junchen asked, staring at the notebook, looking somewhat bewildered.

Ya Ya shook her head blankly, her eyes clear and innocent. Instead of answering his question, she asked in a clear voice, "Brother Zhao, what kind of water is tap water? Is it rainwater, water that falls from the sky?"

"Uh..." This understanding seems to make sense, and Zhao Junchen's eyes cleared for a second.

"No, tap water is purified and disinfected at water plants before being piped to households for daily use. For example, the water in your toilet, the water used to flush the toilet, and the water used to wash your hands are all tap water, which is transported through pipes."

Ya Ya tilted her head and looked at the snow-white wall.

"Is the pipe also hidden inside the wall?"

"Yes!" Zhao Junchen nodded.

Ya Ya immediately became interested, pressed her ear against the wall, and reached out to touch it. There were electrical wires and water pipes inside. How many things must be hidden there? How did they get them in there?

Was it also a gift from the government?

A bunch of questions swirled in Ya Ya's mind, but she knew this wasn't the time for endless questions, so she focused on answering the questions she had just asked:

"Brother Zhao, our village doesn't have running water. We usually fetch water from the river and stream, and collect rainwater when it rains. We used to have a well, but it broke down, and we have to wait for Brother Da Niu to get better so he can fix it! Uncle Zhao also helps everyone carry water to fill the water tanks."

"I see." Zhao Junchen nodded.

Actually, the little guy doesn't even need to say anything; he already knows. Judging from his behavior, he doesn't seem like someone with running water at all.

Could this Lotus Village be a village within an ecological protection zone?

A jumble of random thoughts flashed through Zhao Junchen's mind, only to be interrupted by a barrage of message notifications.

After reviewing the proposals from several suppliers, he still preferred to install an integrated solar water heater with built-in electric auxiliary heating for the village.

The supplier not only provided the equipment installation plan, but also quoted a complete water supply solution, including insulation cotton to protect the pipes from freezing, water storage tanks, self-priming pumps to draw water, pressure tanks for stabilizing water supply, as well as various small fittings such as water pipes connecting various locations, leakage protection devices, and water control valves.

The entire table was densely packed with text.

The other party also prepared a backup plan to retain the original electric water heater, allowing for flexible selection.

After handling the water and electricity supply, the next step is to establish safety and protection facilities.

Based on the current situation in Lotus Village, Zhao Junchen is more inclined to believe that the village is located within an ecological protection zone. Since it's about protecting the ecosystem, there will naturally be more wild animals, and it's only natural for the villagers to take protective measures to safeguard their crops and livestock.

Just two days ago, he saw a video of a village in a protected area being invaded by Tibetan bears.

It's truly a difficult situation for the villagers that such an ugly and ferocious beast is protected and cannot be harmed.

The most suitable way to prevent wild animals from entering is through a high-voltage pulse electric grid for livestock.

Considering that the entire village relies on photovoltaic power, he specifically chose a solar-charged pulse high-voltage grid, paired with a large-capacity battery and a high-power main unit.

This equipment is very comprehensive, with manual adjustment of output voltage and pulse frequency. It is also equipped with an intelligent start/stop switch and relies on photovoltaic panels to continuously replenish the battery, so it can basically achieve uninterrupted operation around the clock.

The main unit itself wasn't too expensive, but the magnesium-aluminum alloy conductive wire was not cheap, and the old man didn't specify how many meters it should be.

It seems unlikely that a decision will be made today.

and……

Zhao Junchen looked at the list he had written in the notebook, his heart filled with worries.

While pulsed power grids may seem convenient, they actually harbor hidden risks.

Improper use or installation can easily lead to safety accidents.

"Ya Ya, where is your village located? Some equipment requires professional personnel to conduct on-site inspections and installations, otherwise problems may easily occur." Zhao Junchen stared at the documents sent by the equipment supplier and asked with a serious expression.
