Pipes, as the name suggests, are channels that are connected with pipes of various materials. Pen & Fun & Pavilion www.biquge.info

Don't underestimate the role of pipelines, why there are few dynasties in Chang'an City after the Tang Dynasty, a big reason is that Chang'an City has been waterlogged since the Tang Dynasty.

Why does waterlogging occur, because there is a big problem with the drainage system in the city, once it rains, the whole Chang'an City will open the mode of watching the sea, and over time, hundreds of years have passed, and Chang'an will gradually no longer be able to live in.

In fact, Chang'an was still called Daxing in the Great Sui Dynasty, and at that time, because of waterlogging, Emperor Wen of Sui Emperor Yang Jian expanded the city once, which is now Chang'an City.

A city's plumbing system can really affect a lot of things, and even affect the development of the city.

Therefore, Xiao Er proposed the definition of this pipeline, and he thought it was very feasible.

It's a pity that he still overestimated the understanding of people in this era, and none of the three bigwigs in front of him showed surprise and interest. On the contrary, Fang Xuanling obviously had a disappointed expression, and said to Xiao Er: "Actually, we have also thought about this channel you said. ”

"Oh?" Now it's Xiao Er's turn to be interested, he didn't know that people had already had this kind of idea.

"Yes, there was a big flood in Chang'an City when it was four years in Wude, and it was because there was no complete drainage that the entire Chang'an was flooded, and even the Emperor Taishang moved to Longshou Plateau to avoid the disaster. Later, we thought about renovating the drainage of Chang'an, but unfortunately there was no good way! Du Ruhui briefly talked about the things of the past few years.

Li Xiaoer's eyes narrowed, he couldn't understand why he didn't want to solve it when he knew there was a problem? A sentence that there is no good way to pass?

Xiao Yu looked at Xiao Er's appearance and said with a wry smile: "Boy, do you think that we old guys can't do anything just by talking?" ”

Xiao Er smiled awkwardly, but still said honestly: "The kid does have this idea." Now that we have figured out the problem, why did we fool it out in no way, think about it, if the problem of waterlogging in Chang'an was solved at that time, then the problem of sending water to the mountains is much easier to solve. ”

The three elders were amused by Xiao Er's uprightness, maybe Li Xiaoer was the first person who dared to speak so presumptuously in front of the three of them, but his honesty just made the three of them have a sharp rise in their favor for him. I don't want to get along with people who have been obscure at a young age.

"Little Er, it's not that we don't do anything, there's really no good way!" Fang Xuanling shook his head with a smile.

Li Xiaoer suddenly realized that he might really take it for granted, and he has been judging people of this era with the thinking of later generations, which is a bit too harsh. And I seem to have overlooked some things, can I really create those things in my imagination in this era?

When this idea came out instantly, I shocked myself. I have been so chic in the past few days that I have forgotten my identity, the era I live in, all I can use is my own hands and wisdom, and the rest need to be limited by the times.

If you want to build an aircraft carrier in Datang, you have to have the kind of technology that can keep up. Li Xiaoer was frightened into a cold sweat by his own enlightenment.

After reflecting on the ideas I gave to Jiangmen in the past two days, or the suggestions I gave to Li Er, or even the ideas I said to the three bigwigs now, fortunately, they didn't involve too advanced theories and clever techniques. If you work hard, you should be able to make it. But in the future, I don't dare to pay attention to it anymore, in case I accidentally say that I made a mobile phone one day, and I still have to kill myself?

The three of them looked at Xiao Er, who was so frightened by Fang Xuanling's words that they sweated on their foreheads, and they really didn't know why Li Xiaoer was like this.

"Little Er, you, are you okay?" Fang Xuanling asked tentatively.

"Huh?" Xiao Er came back to his senses, shook his head and said, "Ah, it's okay, it's okay." The kid thought that what Uncle Fang Shi said was reasonable, and when he was reflecting on what he had done in the past few days, he felt that the kid was too reckless, so he was a little nervous. It made the three uncles worried. ”

Xiao Yu really likes Li Xiaoer, that child will continue to reflect on his past experience because of someone else's words in a short period of time? It's really not an easy thing to do.

Zeng Tzu said that I save my body three times a day, but how many people really do it? Now that this little guy in front of him can really do so much, he is really admired by this old man.

Xiao Er didn't know what others thought, but he was very happy to figure it out anyway, so he said: "I didn't expect to come to Uncle Xiao Shi today, the kid can actually get the teachings of the three uncles and learn a lot of things, I'm really excited." ”

"It's all your own fault, and it has nothing to do with us." Du Ruhui also discovered the most valuable characteristic of Li Xiaoer, that is, self-realization. This is a skill that must be learned in the growing stage of a person, but unfortunately most people tend to ignore this stage, so most of each generation are mediocre.

"Xiao Er, after listening to what we said, do you still have confidence in your pipeline method?" Fang Xuanling still pulled the problem back to the original place.

Li Xiaoer nodded and said: "Uncle Fang Shi, don't worry, the pipe that the kid just said is not the same as what Uncle Shi said, if it can be used, it should be able to solve the problem." ”

"Oh?" At this time, the three of them let out exclamations at the same time, the difficulty is obvious, and it is already in front of Xiao Er, but Xiao Er can still be so confident, which is also incredible.

Li Xiaoer said with a smile: "In fact, the three uncles have drilled the horns, and the reason why you have no way to solve the pipeline problem in Chang'an City is actually two reasons, the problem of pipeline material for a while, but the problem of reasonable laying of pipelines." ”

As he spoke, Xiao Er came to the desk again, spread out a new piece of paper, and began to write, this time all three of them put their heads up, and looked at Xiao Er writing stroke by stroke.

Soon a large box appeared on the white paper, and lines of different thicknesses began to be drawn in the box. The three of them looked at it for a while and still didn't understand, so they simply stopped reading it and waited for Li Xiaoer to finish painting before explaining.

After painting for a long time, Xiao Er was satisfied with his work, and turned his head to look at the three of them with a smile, ready to speak, but he knew that the three of them laughed at the same time.

Xiao Er didn't know why, blinking and thinking about what was going on! This is the three old men laughing back and forth, I really don't know what, Xiao Er looked at it with a confused face.

Finally, Fang Xuanling stopped laughing, and then pointed at Xiao Er with his finger, but Nazhi suddenly couldn't hold back and laughed. Xiao Er touched his face with his hand, looked down, and immediately knew what was going on. It is estimated that he didn't pay attention to it just now, he must have left ink on his face, and it may be a funny look, which made the three of them laugh like this.

Xiao Er himself began to be happy, so he hugged his fists and hurriedly went out to ask Xiao Dezi to help clean it up. After the episode, Xiao Er entered the house again, and the three of them were already studying what he had drawn.

Xiao Er actually drew a general schematic diagram of the reasonable laying of pipelines, and did not follow the pattern of Chang'an's city, but drew a box as a city and laid it inside.

The three of them watched for a long time, and finally Xiao Er helped explain, where it needs to be laid and where it needs to be laid, and how to avoid the intersection of two or more pipelines.

He thought it was simple, but the three adults were impressed by Xiao Er. How did the little guy figure it out and be so organized. And this is not just a matter of retrofitting the drainage system.

Through the specific matter of laying pipelines, the three of them can see Li Xiaoer's thinking and methodical solution when dealing with complex problems, which is a rare ability.

At this point, the three of them no longer have any worries about Li Xiaoer.

"Xiao Er, you just said that the problem of pipe materials, I wonder if you have also solved it?" Or Fang Xuanling asked, there is no way, several prime ministers under His Majesty Li Er have a clear division of labor, Fang Xuanling just focuses on this matter, he must get the exact news from Xiao Er's mouth now.

Xiao Er scratched his head and smiled: "Uncle Fang Shi, in fact, this kid really doesn't dare to talk nonsense, after all, the kid just knew about this matter and put forward such an idea." As for the problem of materials, I need the kid to go down and understand the general situation now, if not, the kid will have to experiment a few more times before he can tell Uncle Shi. ”

Li Xiaoer really didn't dare to take it all in, the idea was good, just open his mouth, but this thing was real, and he dared to guarantee it only if he could get a sample himself.

Fang Xuanling was very satisfied with Xiao Er's serious attitude, he nodded and said, "If that's the case, if you see what you need the old man to help you with, just say it, just hurry up and get the materials that can be used." ”

Li Xiaoer smiled and was about to open his mouth to say that he didn't have anything to help, but suddenly thought of what he was doing in the household department this time, so he immediately changed his words: "Actually, the kid came to see Uncle Xiao Shi this time, but he has something important to do, and he needs the help of Uncle Shi." ”

He was very clever and tied three adults together in one sentence.

"Say, the old man who can help will definitely help you!" Xiao Yu officially spoke. Xiao Er smiled and said, "Thank you Uncle Shi, it's actually nothing, it's just that Your Majesty asked the kid to come to Uncle Shi to ask for some money." ”

Xiao Er smiled brightly, and Xiao Yu's face was very long.

It's also strange to say, a good household book, every time he hears someone come to ask for money, it is definitely Xiao Yu's face. Probably all the books of the household department have always counted sugar roosters, and they don't say anything about it, and they have to get something to finish it.

Seeing Xiao Yu's face, Xiao Er knew that the performance just now was all in vain. Now I have to find another way.
