Live broadcast: Beautiful leader becomes daughter-in-law! Popular all over the Internet

Chapter 483 Great Drainage Channel Design
Netizens in the live broadcast room began to share various temple rumors they had heard before.

But at this time, Sun Ya and the other girls no longer had time to listen.

Because all their attention and energy are on eating.

This meal took them a full hour and a half.

Perhaps because they had eaten vegetarian meals before, they were very satisfied with the dishes this time. They felt that the dishes were very much to their taste and received perfect marks.

After finishing their meal, the girls, led by Xu Wen, started strolling around the town.

At first, the girls thought this was just an ordinary town.

But they soon discovered something was wrong.

Because this town is obviously different from what I imagined.

Not only are the architectural styles here white walls, gray tiles and tall buildings, but there is also a small canal in front of each house.

Generally, the canals in other towns are sewage ditches, which contain all kinds of garbage or children's feces.

But the drainage canals in this township are not like this.

The drainage channels in this township are river water that is directly diverted from the river, and these drainage channels are equivalent to artificially dug river channels.

The ancients actually knew the principle that running water does not rot.

Therefore, as long as there is a steady flow of river water passing through this drainage ditch, there will be no dirt in the ditch. Instead, the water will be clear and transparent and appear very clean.

It was the first time for the girls to see such an architectural design. Even Zhao Xuan couldn't help but ask, "Xu Wen, what is the purpose of such a design?"

Xu Wen explained: "This design actually has many uses, such as keeping away snakes, insects, rats and ants, and it can also reduce temperature and prevent flooding, and it can even transmit some information through this drainage channel."

Upon hearing that a small drainage ditch had so many functions, Zhao Xuan became even more confused.

"Does it really have the functions you described?"

Seeing that Zhao Xuan and the other girls didn't believe him, Xu Wen began to explain one by one.

"Let's talk about the function of preventing snakes, insects, rats and ants first. Have you ever seen ordinary snakes, insects, rats and ants jumping into the river?"

Zhao Xuan shook her head. She had never seen it before.

Xu Wen went on to say: "For us adults, this drainage ditch is just a small ditch that won't drown us, and we can cross it with one big step. But for snakes, insects, rats and ants, it is no different from a real river, and the water here is even more turbulent than the river."

"Think about it, as long as it's not a water snake or a water rat, if other snakes, insects, rats or ants enter this drainage ditch, won't they be washed away in minutes?"

After Xu Wen said this, Zhao Xuan and the other girls suddenly understood, and netizens in the live broadcast room also started discussing it.

"That seems to be true! This drainage ditch is like the moat of this house. Any small wild animals will be stopped when passing through this drainage ditch, unless they take the path walked by people."

"But a path people walk on is easy to be discovered regardless of day or night. Besides, there is only one passage. According to the habits of snakes, insects, rats and ants, they probably won't walk on it."

"It's really great! Why haven't I thought of this method before? I can only say that the wisdom of the ancients is indeed endless. We can never learn it all in our lifetime!"

The netizens in the live broadcast room were really convinced. After the explanation of preventing snakes, insects, rats and ants, the rest became easier to understand.

People who live by the river know that no matter how hot the weather is, as long as you are by the river, the river breeze will make you feel cool.

That's because when the river water flows quickly, it takes away a lot of heat and also brings up a gust of wind.

This kind of wind is the river breeze, also known as the cool breeze.

So if every household now has such a drainage ditch at the door, then you can imagine that there will be wind blowing at the door of every household.

In this way, the river is equivalent to a cooling zone. Legend has it that between each household, the temperature of the entire town is directly lowered.

As for flood prevention, there is even more to say.

Because the water in this drainage ditch is diverted from the river, when the river water rises, the water in the drainage ditch will also rise.

Therefore, experienced elderly people only need to observe the water level of their own drainage ditch to judge the current water level of the main river and whether it will be flooding or dry in the next few days.

With this real-time water level reporting design, everyone can prepare for flood prevention and waterlogging prevention in advance.

After seeing the scale grooves on the drainage ditch, the netizens in the live broadcast room couldn't help but exclaim in amazement.

"Is this something a human could come up with? I even want to build a drainage ditch outside my house now."

"Dude, don't be ridiculous. This is a complete system, and they live in a bungalow. You live in a high-rise building, right? You can't even build a drainage ditch. You can probably build a sewer."

"I've seen this town's drainage system before! Our School of Architecture once had an old professor who specifically introduced this drainage system! I can only say that the design of this drainage system is really amazing. Over the past few decades or even hundreds of years, this town has never been hit by a flood."

"Hey, now whenever I see these things and wisdom left by our ancestors, I always want to cry for some reason. Am I too sentimental?"

"Brother, cry if you want to. It's not that you are too sentimental. It's that our ancestors' exquisite craftsmanship proves that we are no worse than any foreigner. That's why you are so moved that you are crying!"

At this time, Zhao Xuan and the other girls felt the same as the netizens.

I was shocked and utterly stunned at the same time.

If Xu Wen had not led them to conduct in-depth research, who would have known that a seemingly inconspicuous drainage ditch could have so many functions?
At this time, Zhao Xuan and the others finally understood what Xu Wen had said before. Xu Wen really brought them here to broaden their horizons.

There are many things that you cannot understand just by reading books. This is the reason why the saying "Reading ten thousand books is not as good as traveling ten thousand miles" is true.

After visiting the drainage ditch, the group continued walking forward and saw a group of children practicing martial arts.

A coach held a wooden stick and directed the children to practice while shouting slogans.

After asking around, Zhao Xuan found out that these children were all local residents.

The local residents thought it was simple: children are playful and energetic anyway.

Instead of letting them go out and cause trouble, it would be better to find a monk to teach them kung fu and temper their temper and energy.
