Chapter 31
Glass, Waterwheel

The word "villa" has existed since ancient times.

But it was only after the Sui and Tang dynasties that it gradually gained widespread recognition.

Of course.

Before that, villas were more often called "separate residences".

That is, a second residence for self-cultivation and refinement.

Yun Yi hadn't researched this, so naturally he didn't understand these things.

But Zhao An and Zhao Yun's eyes lit up when they heard it.

Villa?

The Immortal called this place a villa, it seems he intends to reside here for a long time.

Great!

As for why it's not called the main residence?

Nonsense, what is the Immortal's status?

His main residence must be in the Heavenly Realm!

Zhao Family Village having an Immortal's villa is already the ultimate good fortune.

Yun Yi didn't know that his casual remark had sparked a brainstorming session for the two.

He led Zhao An and Zhao Yun to the central villa.

"How's this villa? I spent all night crafting it."

All night?

Zhao An and Zhao Yun widened their eyes.

Even the worst house in Zhao Family Village couldn't be built in a single night.

Truly worthy of an Immortal.

Awesome!

Zhao An and Zhao Yun curiously examined the luxurious villa in front of them.

"Immortal Lord, this villa has a peculiar sense of beauty."

"But there are no windows, won't wind and rain blow in?"

"How could there be no windows?"

Yun Yi pointed to the open outer wall, "That's the window, a full-wall, ultra-large floor-to-ceiling window."

The honest boy Zhao Yun widened his eyes in surprise and said:

"My heavens, such a large window, how much paper would be needed to cover it?"

Yun Yi was immediately amused by Zhao Yun's words.

"It's not paper, it's glass."

"And even if it were paper, such a large area, wouldn't the wind and rain tear it apart?"

Zhao An and Zhao Yun asked in confusion:

"Glass?"

Yun Yi finally realized that glass didn't exist in the late Eastern Han Dynasty.

Of course, there was a precursor to glass.

琉璃 (liú lí) - literally "flowing glaze" - a type of naturally formed glass.

However, liú lí and glass are different. Liú lí is typically mixed in color and has low purity.

It is mostly made into vessels.

Using it for windows is very rare.

He immediately explained:

"Glass is a type of liú lí, but glass is pure in color and has extremely high transparency."

I see!

Zhao An and Zhao Yun nodded in seeming understanding.

But they actually didn't quite understand.

Because, let alone glass, even liú lí, they had never seen before.

After all, in this era.

Liú lí is also considered a luxury.

Only noble families would use it to make vessels.

Zhao Family Village doesn't have that privilege yet.

Seeing their expressions, Yun Yi didn't continue to explain.

Seeing is believing.

No matter how much he explained, it's not as effective as showing them.

He suddenly asked:

"Do you have any sand here?"

"Any kind of sand will do?" Zhao An asked.

Yun Yi thought for a moment:

"Preferably the finer kind of sand, the more the better."

Coarse-grained particles aren't sand, they're gravel.

Zhao An pointed north and said:

"There should be the kind of sand you're looking for at the bottom of the Hutuo River."

"Really?"

Yun Yi recalled it.

He vaguely remembers that the Hutuo Riverbed was all cracked mud.

Where is the sand?

Zhao An seemed to understand what was on Yun Yi's mind and quickly explained:

"Immortal Lord, the Hutuo River's sand is hidden beneath the dried-up silt."

Yun Yi slapped his forehead, suddenly realizing.

There is usually river sand in rivers.

The Hutuo River is no exception.

It's just that the Hutuo River's sand is covered by silt, and the silt is dried by the sun into dry soil during drought.

That's why he didn't see it at the time.

"Okay, you two stay here and don't move, I'll go get some sand from the Hutuo River and be right back."

Zhao An and Zhao Yun nodded.

There's nothing wrong with the words on the surface.

But they felt like they were getting the short end of the stick.

Maybe...

Zhao Family Village was built not far from the Hutuo River.

As soon as Yun Yi stepped out of Zhao Family Village, he saw this nearly dried-up river.

Unlike its usual desolation.

The Hutuo River today was quite lively.

He surveyed the surroundings.

Almost everyone here was a villager from Zhao Family Village, and most of them had received milk treatment from Tong Yuan.

Most of them gathered around the Infinite Water Block he had placed earlier.

They used buckets to carry out the Infinite Water, one by one, outside the influence range of the MC rules.

Another group of people stood in a circle.

They were fiddling with a pile of wood.

They seemed to be working on making some kind of large contraption.

"Immortal Lord!"

Someone started it.

The people who were still busy suddenly stopped what they were doing.

They turned their gaze towards him.

After confirming it was really Yun Yi.

They all gestured with clasped hands, respectfully saluting.

Yun Yi waved his hand in response:

"No need to bother me, I'm just here to get some sand."

But the enthusiastic villagers still stepped forward and asked:

"Immortal Lord, do you need help? There are many hands to make light work, we can shovel fast."

Yun Yi shook his head:

"No need, I have a way, you go about your business."

The villagers immediately realized that this was no ordinary person, but an Immortal.

They nodded and went back to their work.

Yun Yi carefully observed the group fiddling with the wood.

He discovered.

They were making a human-powered treadle waterwheel!

They were trying to use the power of treadles to replace the carrying of water, bucket by bucket.

If it succeeds.

It could save a lot of manpower.

The villagers of Zhao Family Village wouldn't have to work so hard day and night, taking turns carrying water.

The wisdom of the working people is truly great!
