After Xie Fei's main force and Lü Mo's main force of 40,000 people converged, they immediately attacked Shang Kexi's troops inside and outside, and then immediately attacked in the direction of Nanjing.

Xie and Lü immediately pursued, but the infantry never caught up with the cavalry, Kong and Geng fought from Ningguofu to Yanzhou, and then fled to Jiangxi through Hengzhou.

Zhao Kang hadn't rushed back at this time, and even if he did, he was already invincible to chase.

On the one hand, military operations were continued, and on the other hand, the situation in the city of Nanjing was stabilized.

Nanjing, the imperial capital, was burned down by one-third after this catastrophe, and the imperial palace was burned down by as much as forty percent.

There is no way to build a brick and wood structure, and even most of the buildings are made of wood, which is so fragile under the licking of the god of fire.

Even the Jinchai Building was burned clean, and Kang Xiaobao sat on the rubble and cried all night.

Compared with the loss of property, Yang Chao is more heartbroken by people, Nanjing, a million-dollar city, after this catastrophe, hundreds of thousands of people died, almost every family wore filial piety, and everyone mourned.

Yang Chao invited the rich families who survived the city, especially in the south of the city, because Yang Chao counterattacked early, so there were many rich families who kept their family wealth.

Tell these people that they hope they will be generous, but not for their donations, but for him to lend the money to the Metropolitan Governor's Mansion at an interest rate of three cents a month.

This is the first time that Yang Chao has put aside the imperial court and acted in the name of the Dadu Governor's Office, Yang Chao printed a large number of bonds, ranging from ten taels to ten thousand taels, hoping that these rich families could spend time with the Dadu Governor's Mansion and lend money to the Dadu Governor's Mansion to rebuild Nanjing, and the words "rebuilding their homeland" were printed on the bonds.

I don't know if it was the common desire to rebuild their homes that touched these wealthy households, or whether they were so confident in the credit of the Metropolitan Governor's Mansion that they generously donated money to sell out the three million taels of bonds printed in one day.

The money was used to rebuild bridges in Nanjing, as well as to dredge pipe ditches and rebuild streets.

As for the money for the people to rebuild their houses, Yang Chao plans to use the funds of Jiangnan Bank to lend. Banks naturally want to lend, otherwise how to make money, the money lent to the people is also three points of interest. This would be impossible if private loans were to be placed at the same interest rate as government bonds in later generations, because the credit of individuals would never be as hard as that of the government.

Already having experience in rebuilding Yangzhou and Huai'an, this time Yang Chao's clerks operated very smoothly.

But this time, Yang Chao is not just about rebuilding.

Nanjing has developed for more than 200 years, and the entire urban area is crowded. The streets and alleys are haphazard.

This is definitely not what the planning looked like in the early Ming Dynasty, don't underestimate the ancients, when the ancients built the city, there were also detailed plans, otherwise such a huge capital city would not be able to operate well for more than two hundred years, not to mention anything else, the drainage system alone would collapse.

If he hadn't studied architecture, Yang Chao wouldn't have known that ancient China had the same drainage system as the West, just like ordinary people. In ancient times, they thought that their country was far behind the West in terms of urban construction.

But the reality is quite the opposite, as the most populous, the largest number of cities, and the largest country in the ancient world, how can it not have the richest experience in urban construction, not to mention that China has the most frequent destruction and new construction, which allows craftsmen to accumulate a lot of experience.

In ancient times, the drainage system was called the official ditch, which was usually located on both sides of the street, and the deep ditch was dug and the round arch was built with bricks. The top layer is covered with a stone slab with a copper coin-shaped drainage hole.

It is strange that later generations of Chinese people only know to praise the Western city-building technology, and almost all the major cities in the country were flooded by the famous heavy rainstorm. Even the imperial capital was deeply immersed in the rain, and was scolded by the people of the whole country.

At this time, everyone moved out of a city as an example, Qingdao, saying that Qingdao was a drainage system left by the Germans, so Qingdao was not flooded, and even the guy who had no brains simply believed that there were accessories left by the Germans more than a hundred years ago in the sewers of Qingdao.

But the same example. Major media and newspapers selectively ignored a small city in Jiangxi Province, Ganzhou.

In this heavy rain, the city of Ganzhou was intact.

Only then did the research know that it was the drainage system built by Liu Yi, a water conservancy expert in Ganzhou City 900 years ago, Liu Yi was the prefect of Ganzhou, and found that the geographical location of Ganzhou City was not good, and it was often flooded, either the rainwater could not be discharged, or the Ganjiang River poured into the city.

Through research, Liu Yi planned the water conservancy system of Ganzhou City, it is to build a large number of official ditches, and the construction is very reasonable, the official ditches of masonry structure according to the height difference of the city's topography, twists and turns, the height of the gentle decline, the method of natural flow, so that the city's rainwater and sewage are naturally discharged into the river.

At the same time, hundreds of ponds of all sizes in the city are communicated, and the regulating effect of the pond is used to filter the debris in the urban sewage, and the sludge is used to raise lotus root and vegetables.

In order to prevent the river water from backing up, the movable water window is added at the water outlet, when the river water is too large and high above the drainage outlet, the water window will automatically be washed to the drainage outlet by the river water to seal the drainage outlet, and when the river water falls, the water pressure in the official ditch can rush open the water window, and the official ditch opens the drainage function.

Such a system can be said to have reached the limit of the technical conditions at that time, Liu Yi named the official ditch Fushougou, from the Fushougou was built nearly a thousand years later, Ganzhou has never been troubled by stagnant water, the ridiculous thing is that in later generations, the Chinese people only know to worship Westerners, and the government is also eager to fill in a lot of ponds used to regulate the official ditch in the city, and sell them to developers to build houses, that's it, Ganzhou still has not encountered floods, which makes people stunned.

Compared with the water conservancy system of Ganzhou in the Song Dynasty, Qingdao has only been in operation for many years, and the rate of population increase, Ganzhou will definitely not lose to Qingdao, Ganzhou's underground passage has no steel water pipes, and Liu Yi has not buried any spare parts in advance, but he is still comparable to Qingdao in later generations.

Ganzhou is just an example, showing that the drainage system of the ancients is not bad at all, that is, when the emperors of later generations were flooded, the Forbidden City was intact, there is only one reason, that is, the Forbidden City is a key cultural relic, and the drainage system is well maintained, while other cities because of the rapid success of the city construction, destroyed the ancient drainage system, not to mention, and did not build a modern drainage system, not to be flooded.

Nanjing City is more than 500 years later than Ganzhou's drainage system, there is no reason to be worse than Ganzhou, but there is a law in ancient China's government, when the organization is strong, the government runs well, and public facilities can be maintained, but in the last days, it begins to decay, the government begins to decay, the organizational ability regresses, and public facilities will be slack.

The same is true of Nanjing's official ditch, not only is the government not maintained, but also the officials and magnates take the lead in sabotage, and those nobles in Zhu Yuanzhang's era lived tremblingly, building houses carefully, for fear that few violations would be seized by Zhu Yuanzhang and cleaned up, but after Zhu Yuanzhang and Zhu Di were two strong emperors, officials and magnates began to be presumptuous.

Gardens such as Xu Da's Zhongshan Palace, not to mention the large-scale encirclement of people's houses, even the streets dare to invade, called the invasion of the street, and the official ditch located next to the street is often the first to bear the brunt, so although Nanjing has several canals, but the city often accumulates water, and it stinks in summer.

In addition to destroying public facilities such as official ditches, the encirclement of the nobles also made the originally relatively regular streets zigzag and extremely narrow, and some alleys could only allow one person to pass through, which was obviously not a pattern that the emperor with grand plans wanted to see.

Therefore, Yang Chao not only wants to restore the official ditch this time, but also re-plan the block, expand the main street, not only restore to the width of the early Ming Dynasty, but also greatly widen, anyway, the city of Nanjing was almost destroyed, the most prosperous place, the tallest place where the houses were built, the more miserable it was burned, because it was not only the key target of the Qing army, but also the most easily burned building.

"Chengnan Street, West Chang'an Street, Xi'an Menwai Street, Hongwu Street and other big streets are all widened to 30 zhang, and second-class streets such as Fudong Street and Zhuque Street must be at least 10 zhang wide, and the width of the small alleys must not be less than 3 zhang!"

Yang Chao divided the city of Nanjing into three classes and handed it over to the head of the white craftsman who contracted the government project.

"But there are a lot of princes' mansions on this street!"

"Demolition! Whether it is the garden of the princes and nobles, or the house of a large family, even if the official office crosses the line, it will be demolished for me. ”

Yang Chao's attitude is very resolute, although many of the garden villas, if the petty bourgeoisie of later generations see it, they will regret and want to die, and think that these are cultural relics, but the winding streets are definitely not a sustainable development of the city, of course, those young people will feel that the straight streets are too charmless, they appreciate the winding winding around at a glance can not see the winding alleys after a hundred meters, the winding alleys are quiet.

Although Yang Chao is also a bit artistic and has a strong literary and artistic spirit, he can clearly see this kind of problem, and will not affect the lives of the vast majority of people and the development of the city because of the unique taste of a small number of people.

Although I feel a little sorry in my heart, but what I built now after a few hundred years is not also an antiquity, and if my own construction is more reasonable, it also saves the trouble of demolition and reconstruction in the future, but preserves more.

So under Yang Chao's strong insistence, the reconstruction and expansion of public works began, the main street was straightened and widened, the official ditch was dredged and repaired, and even the Qinhuai River was completely dredged once, digging out the silt, digging deep the bottom of the river, thickening the embankment, and demolishing all the wharves that encroached on the riverbank, including the wharf of the Jinchai Building, and then planning two riverside streets on the riverbank.

As for the people's building, although it is relaxed, but still made some requirements, such as the use of wood as little as possible, as for the support structure, can the arch be used, anyway, the building span requirements of ordinary people are not large, the use of stone arch structure is somewhat wasteful, the price is higher, but it is safe, and the stone is too expensive, the bricks with advanced skills of the Ming Dynasty can fully meet the requirements, the vault of the beamless hall of Linggu Temple is not built with bricks, hundreds of years of fire, enemy formation, war has not been destroyed.

Although bricks are not cheap, it is also not cheap to transport a large amount of timber from outside, especially when the timber cannot be transported in the Huguang area.

But this restriction is not strict, and it is more encouraged than ordered, but the people who want to borrow money from the bank must abide by this rule, otherwise they will not be able to borrow. (To be continued.) )
