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

A row of small buttons is arranged on the top of the machine. Fang Tiesheng squinted and leaned closer. The buttons were labeled with the words "water level", "program", "start/pause", and "power" respectively.

There's also a small box above that says the remaining time.

At first glance, the text on the left and right sides seems to indicate that one side instructs users on how much laundry detergent to use, while the other side displays the program information, with even smaller and more detailed text.

There are about ten terms such as "standard", "gentle wash", "quick wash", and "single spin".

There is a groove on the top, which looks like a handle for opening the lid.

Fang Tiesheng reached out and tried to lift it up. With a "click," the top cover opened, revealing a cylindrical inner tube, presumably used to store clothes.

He bent down and peered over, and saw a small book at the bottom. He then hunched over and laboriously reached out to pull the book out.

It's the instruction manual.

With this, things will be much easier.

Fang Tiesheng patted the instruction manual carefully and put it in his pocket.

As you walk further in, everyone can immediately spot the clean white squat toilets on the ground.

Such a large, solid piece of white porcelain, with a surface as smooth as snow and polished to perfection, was actually used to hold filth?!

Having only heard Nannan's description, they couldn't have imagined it. Now, seeing these precious artifacts comparable to those from top-quality kilns, everyone was stunned and filled with mixed emotions.

Dr. Chen squatted down and gently stroked the squat toilet, his fingertips trembling slightly.

Such a warm and pure white porcelain, painstakingly fired and polished by craftsmen, should be placed on a table in the hall, offered with incense and candles, and appreciated and played with.

But the people of that region actually used it for...

Not to mention the luxurious materials used, the mechanism is also so ingenious. My daughter said that as long as you press the white box on the back, clear water will flow out from the recess and wash the dirt into the hole with the water flow.

On the wall next to it hung a shimmering, lotus-pod-shaped object, which must be the showerhead that Nannan was talking about for taking a hot shower.

Apricot Blossom gently touched the wall of the room; it was cool and smooth, and when she tapped it with her knuckles, it felt hollow.

Then I looked up at the small square on top.

"Sweetie, what's this square above our heads?"

"Sister Xinghua, this is Daddy Yu!" Ya Ya said, standing on tiptoe to reach the switch on the wall. "Just press this switch and the light will turn on! It will emit a white light. There are other switches next to it, with words underneath. Brother Zhao said it can blow hot air and also..."

There was so much information that Ya Ya couldn't remember it all in a short time.

The big guy stares intently at the top of his head; it lights up when you press it.

The little hand pressed the switch, but the bathroom heater didn't respond at all.

Ya Ya was a little puzzled, because she had tried it before and the light would turn on.

Oh, right, they don't have electricity here!

Ya Ya pouted, wishing the village would have electricity someday.

Fang Tiesheng looked at the little girl's downturned mouth, stepped forward and gently patted her shoulder: "Darling, we don't have electricity here, so it probably won't work. But we have water and flashlights. We'll ask Uncle Zhao and Brother Da Niu to finish building the septic tank as soon as possible, and then use a large vat and pipes to bring the water over. Although we can't turn on the lights, we can still use the squat toilet."

Ya Ya looked up at Grandpa Fang, blinking her eyes, as if she had forgotten something.

"Yes, little girl, let's go work on that septic tank now. We'll get the materials and it'll be quick, don't rush." ​​Da Niu held a shovel and showed Ya Ya his arm strength.

Ya Ya was still frowning and thinking seriously. Oh dear, what did she forget?

The group lingered in the three-in-one bathroom for quite a while before reluctantly leaving. Zhao Hu, Da Niu, and Doctor Chen were already standing in front of piles of cement and bricks.

"Did we buy too many materials?" Dr. Chen opened the "Barefoot Doctor's Handbook" he always carried with him. There shouldn't be so much cement, it's just a pool. And it seems like we're a little short on pipes.

Could it be that Boss Zhao took advantage of Nannan's young age and fooled her?

Doctor Chen was slightly dissatisfied. He couldn't even fool a little kid; this person wasn't very honest.

Ya Ya led Grandma Liu out of the house, her gaze falling on the book in Doctor Chen's hand. Things she had been vaguely remembering suddenly became clear.

"Grandpa Chen!"

Ya Ya let go of Grandma Liu's hand, ran over, took out a small notebook from her spatial storage, and handed it to Doctor Chen: "Grandpa Chen! Brother Zhao said that our septic tank is a very old style from their area, and it doesn't work well. He told us to make it like this."

Dr. Chen took the notebook.

"Brother Zhao also said that the new method will use more ingredients than the original one, and I agreed because I remembered what Grandpa Fang said about listening to Brother Zhao!"

Fang Tiesheng also joined in upon hearing this, and the two stared at the drawings in the notebook.

The more I look at it, the more I appreciate its ingenious design.

Below that, in smaller print, are the quantities and prices of each material.

Dr. Chen's face flushed slightly; he had previously made malicious assumptions about Boss Zhao...

"Nannan is so smart. The one drawn by Boss Zhao looks much better." Fang Tiesheng gave Ya Ya a thumbs up in approval.

After carefully reading this page, I turned to the next page and saw several more lines of neat handwriting, the handwriting of which matched the handwriting on the note on the medicine box.

This...this is the handwriting of Fairy He Miao.

Fang Tiesheng adjusted his reading glasses, leaned closer, and let out a long sigh after reading the words.

electricity.

They will have it.

It turns out that it wasn't that there weren't any available for sale; there were other accessories that needed to be purchased together.

It's not enough to just buy the board.

Indeed, such a magical method of converting sunlight into electricity could not be accomplished with just a few blackboards.

Thanks to He Miao and Boss Zhao for their thorough consideration; not asking clearly would not only have caused trouble but might also have been inappropriate.

Dr. Chen also leaned closer and said, "Brother Fang, this thing called solar power generation is something that most of us don't understand. The words are written clearly, but it depends on how much electricity we need."

Neither of us has been there before, so you'll have to put in a lot of effort. I noticed that the white things on the wall in that bathroom probably require electricity; they even use electricity to heat the water there. Electricity has many uses, so it's best to list as many as possible electrical items you can think of—that way, it'll be safer.

Fang Tiesheng nodded repeatedly, "I know, I'll make a copy first. You take the notebook. We need to hurry up with the septic tank, the weather's been fine these past few days."

The wall in the backyard is now completely dry. Compared to the stone wall next to it, which is made of mud, it is much sturdier. Not only can it not be pushed down, but it won't break even if you hit it with a little force.

Water flowing down will only slide off the surface and flow away, rather than quickly penetrating.

People have gained a deeper understanding of the wonders of cement.
