Handan is an ancient city, there is no doubt about it.

In modern times, "ancient city" is a kind of praise title, which proves that a certain city has a strong culture and heritage, but "ancient city" is not a word of praise in contemporary times, but the simplest word is used to describe the dilapidation and backwardness of a city.

The construction of the city in the Spring and Autumn Period and the Warring States Period was not without planning, and it was basically a continuation of the "well field system" in ancient times. The so-called "Ida" does not need to understand the meaning of the text too much, but it is actually the shape of the font. That's right, just like the acres of land, the planning of the city is also divided into areas, and a certain place is a lifang, which must be a boxy shape at the beginning of the planning.

The use of items will become old, and the city will change its original appearance in the continuous changes, Handan must be orderly at the beginning of its establishment, whether it is a building or a reason, it must be the implementation of the pattern of clear lines, but the pattern will be changed in the passage of time and historical changes, and the place that should have been used as a road has been encroached upon, and the "orderly lines" in the orderly are gone, and there is no longer any "orderly".

Looking at the appearance of a country's capital can detect the rise and fall of the country, the stronger the country, the more her country must be full of order, and the "order" here not only refers to security, but also the planning of roads.

Lu Zhe has been to Xianyang, although Xianyang does not have a straight avenue through the city, but the roads in Xianyang City are definitely not like Handan City, there is no avenue of more than one mile, and there is absolutely no garbage piled up on the roads in Xianyang City, which is obviously a waste product.

What is the most exaggerated? When Lu Zhe went up to the city tower and looked into the city of Handan, he saw that the buildings were very dense, and some narrow alleys were more complex than spider webs.

"How can outsiders identify the geography of Handan?" Uncle and grandson made a loud noise.

Lu Jia and Li Shiqi glanced at each other, and Li Shiqi asked an official of Zhao State, "Didn't you consider the fire?" ”

The official of Zhao State who was questioned said a few syllables vaguely, probably in a daze.

The buildings are dense and the alleys are narrow, but many of the alleys can be seen to be piled up with debris, and if there is really a fire, it will definitely spread.

The layout of a city tests every aspect of a city. It was not only the height and majesty of the city walls, but also the layout of the buildings and the planning of the roads in the city.

Handan doesn't look like a city that can stand the test of war, and there is no smooth road to mobilize the defenders in the city, which means that there is no way to rush to the aid in time when the war is tight in a certain area.

Lu Zhe, who was standing in the city tower, didn't see the defensive equipment, he took a special look at the card slot where the bed crossbow should have been placed, because of the groove, it would definitely cause water accumulation in the rainy season, and there was moss growing inside.

The current season is winter, and the rainy season in autumn has only passed for long, and it is not a matter of a month or two for moss to grow in a place, Lu Zhe looked at a few in a row to either place a bed crossbow or a card slot where an oil pot should be placed. It is not uncommon to find mossy card slots, and even in some of the warehouses where the wood should have been stacked, they are empty.

It should have been nearly four years since Wang Ben led his army to threaten Handan? In the past four years, Zhao Guo has been increasing the guard strength of Handan, so he shouldn't pay less attention to the defensive equipment!

No one knows what Lu Zhe was thinking, and the officials on both sides of Han and Zhao who accompanied him to the city tower were chatting about the difference between Handan and Nanling. And to be honest, it's really unfair to compare Handan with Nanling......

"This is the north of the city." Zhang Er said.

Lu Zhe was looking at the busy crowd, and he also saw a lot of stalls, and some people were also moving goods in and out.

In ancient times, the north and west of the city were all stored with markets, and the east and south of the city were the main places of residence.

Handan is a big city. The population would not be less than 350,000 at best. In a city of 350,000 people, there are only two markets in the north and west of the city, according to the ancient plan, the west of the city is basically a place to sell livestock and bulk commodities, and the north of the city is mainly retail.

A city with a population of 350,000 people. The retail market is concentrated in the north of the city, and in other places, except for some merchants who carry the burden and sell no zài shops, then the goods that people in the entire city need to use every day are here, and it seems that it is naturally crowded.

As a traverser. Lu Zhe is not without the experience of going to the vegetable market to buy things, in fact, as long as it is a vegetable market, there is no place that is not chaotic, and what occupies the road. What goods are put on a random shelf, what stalls are piled up, that is a very common thing.

What does Zhang Er mean by that? He just wanted to say what Lu Zhe was thinking, don't expect a group of stalls to beg for a living, how strong the concept of order can be, dirty and messy is what the market should be, if it is not dirty and messy, it is a high-end club, not a retail market.

A group of people from the Zhao Kingdom could see that the people on the Han side had disdain in their eyes, and some of them asked if the north of Nanling City was not like this?

Nanling City is really not like this, Nanling's retail market in the north of the city is a grid-like pattern, Lu Zhe has also brought the modern supermarket concept to the present day, and Nanling City also has a subterranean system that Handan does not have.

In addition to the underground sewer system, any of the ideas "brought" by Lu Zhe are modern products, and the experience that has been precipitated by history is not necessarily correct, but no matter how advanced it is, after all, human beings are always developing and progressing.

Li Shiqi introduced to Zhang Er what is called isolation alley, which is a necessary fireproof vacuum belt. In addition, he is also explaining the water pipe system to Zhang Er, telling about the tap water that can be found everywhere in Nanling City, and the toilets that ensure the cleanliness of the city.

"It turned out to be a pottery pipe and that thing called water pressure control, no wonder there are so many fountains in Nanling City." Zhang Er's wisdom is not bad, and he is no stranger to pottery, he shook his head and smiled bitterly: "Nanling is a new city, Handan is ......"

Yes, Handan City is an ancient city, and it is not easy to rebuild it, so what if Zhao Guo and others know the planning of the city? Demolition and reconstruction are basically not feasible, if you really want to do that, just wait for the citizens of Handan to riot and rebel.

The first to use pottery pipes as a water conveyance tool was not the Han State under the rule of Lü Zhe, the Qin State had been using pottery pipes as water transmission facilities as early as more than 200 years ago, but the Qin State did not discover the theory of water pressure, and the pottery pipes were only used as underground water transmission systems in some areas where water must be transported and roads.

In modern times, water conservancy systems of the Qin State can also be discovered, and water conveyance facilities buried in the ground by the Qin people have been found more than once. This method is the most common in the irrigation system of the field, the scientific research personnel found the largest irrigation system, the longest pottery water pipeline buried under the ground by the Qin people has reached an exaggerated 30 kilometers, and there is a pottery water transmission system that runs through the heart of a mountain, and I don't know how to do it with the technology and conditions at that time.

The development of pottery water pipelines is mature, and the research on the theory of water pressure has accumulated enough experience, so the structure of the flushing toilet is not very complicated things must have been studied, and the Han Kingdom currently sells a lot of goods to the outside world, but the best selling goods definitely have flushing toilets.

Zhang Er is saying to Li Shiqi about the flushing toilet, there are many people in Handan City who buy flushing toilets from Han merchants, and it is not difficult for them to get pottery water pipelines, but there is a very critical problem, that is, Handan City is not like Nanling City is located on the edge of a big river, Handan City is not as developed as Nanling City has such a developed water conservancy system, flushing toilets are popular throughout Handan, and the public bathhouse model of Nanling City is also imitated, and a large amount of water has caused great trouble to the water source of Handan.

Not only the sanitary conditions, the weak always have the nature to learn from the strong, and there are many times are "crooked", learning is to the convenience and enjoyment of life first began to imitate, Nanling City can be seen everywhere fountains, many people with economic conditions if there is no water spray statue or swimming pool is simply ashamed, Nanling as a country is driving the taste of life in the entire Han Kingdom, as a powerful country of Han is also driving the pursuit of life in the Oriental world.

Naturally, there will be no public parks and fountains in Handan City, but it does not prevent some qualified people from playing in their own courtyards, and the result is ......

"Oh? The water level of the wells in Handan has been dropping? That is the use of groundwater is too flooded, and it is better to find a master to explore, not to cause subsidence like Linzi. "If a few years ago, Li Shiqi would never have been able to say such a word, and the master he said was not a Taoist priest or a monk, but actually a person who studied the quality of the soil.

At present, there are many schools of thought that study soil and mountains and rivers, and farmers, Mohists, Yin-Yang families, and miscellaneous families are involved in similar research, but the most professional ones are famous masters who can't be smashed with eight poles.

What does a famous artist do? In fact, he is a debater, and what he is best at is the "white horse is not a horse". The reason why it is said that there is a study of soil and mountains and rivers is actually a bit nonsense, just because "Shi Lu" is such a great person who was born in a famous family, but he was appointed by the first emperor to build a spiritual canal, and has a strong ability to observe and create.

The Han Kingdom also needs a spiritual canal to connect the waterways of Shudi, Badi, and Qiandi, so Shi Lu is naturally under the command of Lu Zhe, and this time Lu Zhe went north to take Shi Lu with him, and now he just let Shi Lu help the old man to explore Handan, but don't make the matter of subsidence because of more than moderation with water.

"It's a great talent, the king has entrusted him with a heavy task, and Shi Dajiang has not lived up to the king's order, and the army can maintain logistics and grain in the north, thanks to Shi Dajiang exploring the mountains and rivers all the way."

Zhang Er panicked when he heard that Handan City might have a sink, where did he have the time to listen to what a master had done? (To be continued......) R1292
