On the south bank of the Kunming Canal, Tian Xin is planning drawings.

On the south bank is Longshouyuan, where the line of sight is flat, and the slope difference is about 30 meters...... It's a godsend for civil construction freaks.

If you build a new city, it's really beautiful.

There is no need to expand the foundation, nor do you need to build a large-scale and high-cost city wall, as long as you plan a number of squares, you can complete the layout of the city.

In the early stage of city building, as long as two standards are established, the city circle can be expanded outward by drawing a gourd in the future.

The first standard is the road standard, which is easy to do, the main road of the new city is crisscrossed in the center of the city, the main road is a first-class road, the tentative width is 64 steps (about 88 meters), and the second-level road is 32 steps; The neighborhood is a third-class road with a width of 16 steps; The cross street in the square belongs to the fourth grade, and the width of the road is eight steps; The laneway in the square area is a five-level road, with a width of four steps (5.5 meters).

The second standard is the square, one mile and three hundred steps, each square is three miles and nine hundred steps long from east to west, and two miles and six hundred steps wide from north to south; With the Qin system of a house 30 steps square as the standard of the house, then in addition to the area of cross streets, lanes, and vegetable plots in the square, there can be 384 standard houses.

The area of a standard house is a large courtyard with a length and a width of 30 steps, and one step is six feet and about 1.3 meters, and such a large courtyard covers an area of 1,700 square meters.

Naturally, such a house was for lieutenant-level officers; Other sergeants who were relocated to the square were given two households and one house, three families and one house, or four families and one house, or six families and one house, depending on the rank.

There are two houses for school-level military officers and three houses for major generals, and one house is added for every level of military rank that the general increases; The title adds additional mansions, one house for the king, two houses for the pavilion marquis, four houses for the township marquis, and eight mansions for the county marquis; Each house can open up a vegetable garden in its own courtyard, as well as a vegetable field in the isolated area of the house.

The establishment of each battalion in Beifu is similar, and there is a difference between the increase and decrease of about 30 soldiers at most, but the overall establishment is the same, and a battalion has 17 teams, regardless of the cavalry battalion and the infantry battalion, which are all certain death.

In the calculation, one square can house two battalions of officials and their families, about 1,500 households.

The officials of the northern province did not pay taxes or rent, and they did not pay military salaries when they went on expeditions, and their main income came from war booty, farming, handicrafts, and business.

In this way, they lived in the Xinchengfang area, and in addition to conscription, the rest of the family could only engage in manual production, or engage in business, or hired labor.

Therefore, the square areas planned by the new city cannot be spread out too much, because these urban neighborhoods can only rely on handicrafts and service industries to obtain wealth and accumulate family business.

The vast Guanzhong area is in urgent need of development, and it is necessary to set up townships and villages in the countryside; If there are officials who do not want to continue to serve, they can be discharged from the army and reorganized into township and village communities.

Therefore, the planned new city will set up a maximum of four or six squares, and when the productivity of Guanzhong gradually recovers, more neighborhoods can be expanded.

Fang, literally, is a boxy complex of buildings protected by low earthen walls.

The Guanzhong area is paved with various professional development workshops, and then the wooden rails are built to bypass the Sanmenxia Gorge that cannot be passed by Cao Yun with technology, so that the grain of the four states in the Kanto region will enter Guanzhong with endless energy sources and low cost.

If the Guanzhong region receives an adequate, low-cost food supply, it will be able to control the pace of development and keep the lush forests.

If there is no food, Guanzhong, whose population is growing more and more, will sooner or later cut down trees and open up arable land for that bite to eat, until the environment collapses...... No matter how much land and fertile land are cultivated, without water irrigation, it will become dry land and cracked wasteland.

In this process, ensuring the combat effectiveness of the government soldiers is a crucial part; The government soldiers have combat effectiveness, and the Kanto region has an endless source of energy to transport grain to the west; Imported food from outside would allow the majority of Guanzhong's population to work in other industries than agriculture.

Otherwise, Guanzhong will have to invest at least 900,000 people in agriculture for a population of one million.

Handicrafts are also industries, reducing the agricultural population, Guanzhong can develop other industries and accumulate first-mover advantages.

There is little agriculture in the Guanzhong area, and the vast wilderness can be used for animal husbandry development, providing ploughing cattle and farm tools for the four prefectures of Kanto and the south; Mutual subsidy, mutual exchange, conducive to long-term development.

Finally, slowing down the pace of agricultural development in the Guanzhong, Beidi, and Shangjun areas will naturally reduce the sediment accumulation rate of the Yellow River, and then reduce the water conservancy expenditure of the four Kanto prefectures.

Tian Xin vaguely remembered a saying that almost all of the taxes of the Henan political envoys of the Dashu Dynasty were kept in local expenditures, half of which were fixed local financial expenditures, and half were given to the imperial court, which in turn was reused for Henan's river administration maintenance projects.

In any case, as long as the wooden track is repaired and Caoyun can skip the big pit of Sanmenxia, there is no need for transitional development in Guanzhong.

As long as a generation of recuperation is used to repair wooden rails and railroad tracks, wherever the tracks are, they are all summers.

Tian Xin's development ideas are smooth, and it is simple for the military officials of Beifu, just implement it step by step, as for the consequences...... No matter how bad it is, it's not much worse.

For the low-level officials and the common people, in fact, they don't have any feelings about what they plan or don't plan, it's all life.

Whether the plan is good or bad, whether it will work or not, is a bit far away for them, and even if they feel the changes in their lives, it is not easy to perceive the difference.

The planning and development of Guanzhong is a systematic project, and Tianxin and Beifu also have relevant bills.

But in these preparatory proposals, there is no place for Wei Yan, the five thousand Xifu soldiers.

Wei Yan tidied up his hair and beard a little, and after changing into clean clothes, he came to look for Tian Xin, if he didn't come, Tian Xin would also invite him to a banquet.

It's just that Wei Yan came a little fast, and saw the scene of nearly 30,000 people working on both sides of the Kunming Canal.

The 20,000 troops from Hebei and Hedong were disarmed and immediately put into production, and they were also working with Tian Xin's pro-army Sanwei.

More Zhuhu captives...... was demoted to his own slave by Tian Xin in one breath, anyway, these tribes eat this, and even Wu Zhen can initially tame these people, and he has no reason to fail.

Before and after, there were nearly 120,000 nomadic and half-pastoral populations such as Xiongnu, Qiangqi, Yueshi Qinhu, Zahu, and Hexi Xianbei, which were swallowed by him.

In other words, these 120,000 households, along with their livestock, will become Tian Xin's personal property, and will not appear in the imperial court's war reports, nor will they be handed over to the imperial court for disposal.

120,000 households can easily raise an army of 100,000 without extreme mobilization.

At least half of the population will be split up and gradually integrated into the big family of Beifu; Assimilation can be completed within a generation of the lifestyles of various fangs.

The remaining 60,000 households also plan pastures in the form of workshops and are divided into different places...... No one will collect taxes from them, as Tian Xin's slaves, whoever collects taxes from them will collect taxes from Tian Xin.

Therefore, the animal power they shepherd is naturally Tian Xin's industry, and they can take it away if they want to.

But there must be a limit to this kind of thing, how to milk the cow is an art, in short, these people must be fed, live a good life for a few days, and then charge a little bit of interest on breeding.

Before Wei Yan saw Tian Xin, he was shocked by the scene in front of him.

Since following the first emperor, many battles have been fought, and the largest battle is the Battle of Hanzhong, but the Battle of Hanzhong rarely breaks out into a frontal decisive battle.

He took over Hanzhong, which was a no-man's land, so the scene of more than 30,000 people working on both sides of the vast and flat Kunming Canal made Wei Yan ...... Eyes.

As for the scene of the Grand Army of 100,000 decisive battles...... Sorry, Wei Yan didn't experience it.

So much so that he, the general of the expedition to the west, was in the eyes of the middle and senior military officials of Beifu...... The water is a little large, so naturally it is not possible to talk about heartfelt and heartfelt respect.

Soon Wei Yan saw Tian Xin, who was indeed inspecting the winter wheat planting work in the Kunming Canal, and was indeed planning a new city.
