Become the city lord from today

Summer has arrived, the weather is getting hotter, and many construction sites have to put sackcloth on their heads to shade the sun before they can continue to work.

Liu Feng is dealing with government affairs in the study, and the study is now a steamer, which is very stuffy and makes people feel irritable.

"It's so hot, it's really hot." Allie spoke out weakly, lying limply on the table, opening her mouth and spitting out her little tongue, wearing a vest, and her white and tender shoulders were exposed.

"Calm down." Liu Feng put down the document and wiped the sweat from his forehead.

"Young Master, I can't calm down, I'll be irritable when it's hot." Allie pulled the shoulder straps of the vest, and one side of the shoulder straps was ripped off, revealing the white and tender reddened shoulders.

"Allie!" Nicole hurriedly spoke up, white-eyed fox-eared lady's defenseless behavior.

"Huh?" Allie turned her head incomprehensibly, looked at Nicole and asked, "What's wrong?" "

"Whoosh!" Nicole picked her chin and pouted at the fox-eared lady's shoulder.

"Huh?" Allie looked sideways, her cheeks instantly reddened, and she quickly got up and hurriedly pulled the shoulder strap back on.

The vest she is wearing now is still given to her by the young master, and the sister paper in the castle is all handy, especially when she sleeps, it is very cool.

"Hee-hee..." Mina chuckled, her blue eyes flashing strangely, and teased, "Allie, what are you trying to do?" "

"I, I didn't, didn't do anything." An Li shouted, her brown eyes looked at Liu Feng, and when she saw a pair of smiling black eyes, her cheeks turned even redder.

"Well, if it's really too hot, I'll think of a way." Liu Feng spoke up to relieve the fox ear girl.

It's been a few days since they left Eliza and Dalena today, and he still hasn't waited for Tice and them to bring saltpeter over.

"What way?" Allie hurriedly asked, she was not concentrating now, and when she thought of distressing things, her mood would quickly become irritable.

"Nicole, go to Neku and bring the box number seven hundred and twenty." Liu Feng turned his head and ordered Nicole.

"Okay." Nicole got up, pulled over a linen coat hanging next to her, and draped it over her polished shoulders.

In the hot weather, she also wears a vest, but she will only wear it in the study and room, and she still has to be conservative when she goes out.

"Kayi..."

Liu Feng looked at the open study door, turned to Allie and asked, "What happened to the game pool I let build?" "

It was hot and it was great to have an indoor pool.

He had never dared to have an indoor play pool on Earth before, and now he was a lord, which was too simple.

"It's already been dug, but the tiles are still being fired." Allie said with anticipation, she was also waiting for the construction of the swimming pool to be completed.

"That's good." Liu Feng nodded, thinking of the problem he hadn't paid attention to before, and asked, "What happened to the tap water?" "

"Half of the people were connected to the water, and everyone was very happy that they didn't have to go out to fetch water." Allie said happily.

"Let people pay more attention to the source of the reservoir, there must be no problems." Liu Feng instructed the cat-eared lady.

"I've made the reservoir a no-go area, and not a single mouse is put in it." Mina said with a serious face.

She has recently been learning health knowledge with Allie, Nicole, Weiya and others, especially the knowledge of plague and viruses.

"It doesn't seem that you can rely entirely on reservoirs for water." Liu Feng touched his chin and thought of using the siphon principle to supply water to Xiyang City from the Youshui River.

The principle of siphon is to use the force phenomenon of the height difference of the liquid level to fill the liquid into an inverted U-shaped tubular structure, and place the end with a high opening in a container filled with liquid, and the liquid in the container will continue to flow out to a lower position through the siphon.

In other words, Liu Feng needed to find a river with a water level higher than the parallel ground line of Xiyang City.

Now the water supply in Xiyang City is enough, but it is not enough to add people later, which makes him have to think about it in advance.

"Young Master, are you thinking about the new city?" Allie frowned, she had seen the design plan of the new town, it was a large area of tall buildings, just like a forest.

"Yes, when the new city is established, there will be not enough water." Liu Feng replied casually, took out the map and began to check it.

"Young Master, there is a lake in the mountains here." Mina looked sideways at the map, suddenly pointed to the edge of the map and said, "However, it's a little far from Xiyang City. "

"Far away?" Liu Feng frowned, he knew this lake, it was located in the Forbidden Mountains, and the terrain was also very high, it was a living water lake.

He took the ruler and looked at the scale and thought, if the pipe is supplied with a siphon phenomenon, it is enough to supply a piece of urban water, and the pressure is also enough to send water to tall buildings, which is much stronger than the water transported by the reservoir.

Liu Feng turned to Mina and said, "Let people give me that area as a forbidden place, and send people to clean up the surrounding animals." "

"Yes." Mina quickly answered.

"It seems that the principle of siphon should also be included in the teaching knowledge of schools." Liu Feng muttered to himself that the construction of many cities in the future will need to use the principle of siphon, especially some water conservancy and other governance.

He felt that it was necessary to sort out a set of siphon water supply series knowledge, as well as hygiene knowledge.

The weather is hot, and the water source can easily be contaminated.

Especially in some cities, when there is only one source of water, once it is polluted, it is easy to drink one city to death, and there is no water supply plant to treat the water.

Moreover, after his students go out, the governance side needs some scientific knowledge, and there are always no convenient conditions, so it is better to carry water or dig wells all over the ground.
