Zhao Yu was stunned when he heard Zhou Xiang's rhetorical question, in fact, as long as the screw water lifter is reversed, it can be turned into a water-powered transmission mechanism, and many early hydropower stations use similar structures. Nowadays, in this situation without electricity and engine power, wind and water have become few options, and compared with the two, he thinks that water output is the most abundant and controllable in terms of driving machinery.

In the past, most of the machines used to drive the workshop were water wheels, but they would be affected by the abundance of river flow and the season, but with the screw water lifter, the water can be lifted to the high reservoir at any time, and then another group of water lifters can be used to drive the machinery by using the power generated by the potential energy generated by the underwater discharge, so as to obtain sustainable, stable and abundant power.

Zhao Yu was surprised that he knew it by relying on the knowledge of his previous life, while Zhou Xiang had only just come into contact with it, and he was afraid that he didn't understand the principle, but he thought that it could be used in reverse based on experience. Think about the world as it is, knowledge is obtained and accumulated through practice, and you are just standing on the shoulders of the great masters of history, as long as you pass on what you know to them, maybe you will achieve higher achievements and develop more functions.

"Your Majesty, is it not possible for your subordinates to say?" Seeing that the little emperor was just staring at himself deeply, and he felt that there was nothing wrong with touching his face, Zhou Xiang was a little flustered in his heart and asked suspiciously.

"No, I think you said it well, I didn't even think of it!" Zhao Yu listened as if he had 'come back to his senses', and sighed a little.

"Your Majesty also thinks it is feasible?" At this time, it was Zhou Xiang's turn to be surprised, he didn't expect that his idea would be recognized by the little emperor, but he was a little skeptical.

"Absolutely." Zhao Yu nodded very affirmatively, and said, "It's just that there are a lot of things to do now, you can bring this back and study with the masters how to put it into production!" ”

"Yes, my subordinates obey!" Zhou Xiang was of course very happy to be recognized by the emperor, and hurriedly held the model in front of him, as if he was afraid that the emperor would regret it.

"This time, I will take over as the right attendant of the Ministry of Works, and I am also under a lot of pressure, so I must do things well." The little yellow door put away the things and sent herbal tea, Zhao Hao waved them back and took a sip of tea.

"My subordinates understand that those scholars always look down on us who have no merit and fame, and they always feel superior to others, and they all look at us with blank eyes." Zhou Xiang said with a smile.

"Hehe, this time in the Ministry of Industry, if you still have to be in charge of the construction and capital of the institute, and still be in charge of the ordnance superintendent, you are more familiar with these affairs, and after you are slowly familiar with the affairs of the ministry, you will make another arrangement. I still have great expectations for you, and I can share more things for me in the future. Zhao Yu also chuckled when he heard this.

"My subordinates will do their best to share your majesty's worries!" Zhou Xiang said with a deep salute. When he heard this, he was also very emotional, thinking that he was just the commander of an ordnance supervisor back then, in charge of a group of craftsmen, and he thought it would be the end. Who knew that people were not as good as heaven, Da Song suddenly ended, his own rice bowl was also smashed, and he followed the line of exile. But who knew that he met the little emperor by chance, and now he stepped on the fast track of life, and listening to the emperor's meaning, he still has room to rise, which naturally makes him overjoyed.

"This renovation of Lin'an City must be made into a hundred-year-old and thousand-year-old project that can benefit future generations, and you can also shine in the annals of history!" Zhao Yu nodded.

"Yes, my subordinates will never live up to His Majesty's expectations!" The emperor lifted himself, Zhou Xiang naturally wanted to continue, and he also understood that he was only in charge of the construction of weapons before, but now he has to manage the Ministry of Industry, although there are many obstacles to the rectification of Lin'an City, but if he does this well, he can also establish his position in the Ministry of Industry, and then he can be regarded as a foothold in the court.

"Yes, very good. I also know that this matter is not easy, and it is indeed difficult for you! Zhao Yu nodded, but said gloomily.

"What Your Majesty said, it is the responsibility of his subordinates to share the worries for the king, not to mention that it is just a little difficult to do, even if it is a mountain of swords and a sea of fire, it is also a matter of death." Zhou Xiang bowed his hand and said solemnly.

"Well, this matter is very involved, and the imperial court is unwilling to allocate money, and my inner treasury is not rich at the moment. But don't have any worries, if you have difficulties, just say it, I will make the decision with you, just let it go! Zhao Yu looked at his words but didn't look like hiding his selfishness, and nodded with relief, he knew that this kind of thing would inevitably offend people, and Zhou Xiang's shoulders couldn't bear it, and only he could withstand the pressure from all sides.

"Your Majesty does have something unspeakable, can you tell your subordinates to listen to it, and maybe you can solve your Majesty's worries!" Zhou Xiang knew that in order to transform Lin'an City, the little emperor and the ministers of the court were not very happy, and he also understood that this matter was difficult, and if it was not done well, it would damage his reputation. And he also knew that the little emperor was not a fool, he didn't know how to seek advantages and avoid disadvantages, but he insisted on trying to do this by all means, it must be for something, otherwise why cause such a big trouble!

"It doesn't hurt to say that this matter has anything to do with you!" Zhao Yu took a sip of herbal tea and said in a deep voice, "The transformation of Lin'an City is said to be for the benefit of the country and the people, and you also know that the rivers of Lin'an City are silted, sewage flows sideways, and garbage is everywhere, which is very easy to cause epidemics." I have inquired that there have been more than ten major epidemics in Lin'an City in the past 30 years, and small epidemics have broken out every year, even two or three times. Therefore, the number of soldiers and civilians who died was in the hundreds, and the number was tens of thousands, all of which were related to this. ”

"In addition, the city has seriously encroached on the streets, except for the royal street, the secondary roads have been encroached upon, not to mention the passages between the streets. And you also know that roads are not only for ease of passage, but also for isolation and fire prevention. At present, the city is adjacent to each other, and once the fire starts, there is no partition, and if it is not done, the whole city will be burned, which will not only cause heavy casualties, but also how many people will be displaced. ”

"What Your Majesty said is very true, a few days ago, there was a fire in the Zhaoxianfang house, only two streets away from the gunpowder workshop, fortunately it was found early, and it did not cause a major disaster under the joint rescue of the guards and patrol shops, but it also burned down the house for more than 30 years. If the powder magazine is ignited, the entire military workshop will explode, and I am afraid that half of the north of the city will be razed to the ground. But in such a matter that benefits the country and the people, why can't those courtiers understand His Majesty's benevolence? Zhou Xiang said indignantly.

"Again, I'm also a little selfish." Zhao Hao said with a wry smile, "Now the housing prices in Lin'an City are abnormally high, and after the Xing Dynasty moved back from Qiongzhou, many people have exhausted their savings for many years, and it is difficult to exchange them for a house. Even if the left is leaning towards all his own, he can only buy a three-entry house, and three generations of a family are crowded together. Master Ying didn't save any money, and after returning to Lin'an, he couldn't afford to buy a house, and the children of the family came to vote, they took refuge for many years, and they couldn't come up with the money at all. ”

"What Your Majesty said is that it is indeed not many people in the DPRK who can buy a house in Beijing, if it were not for His Majesty's mercy to give him a house, it would be difficult for many deacons to gain a foothold in Beijing!" Zhou Xiang nodded yes, in fact, he also relied on some money accumulated by His Majesty for many years to buy a two-entry mansion near the outer city, which was very cramped.

"Although I have given them some houses, they will still be vacated once they leave office. And these old ministers who have followed me for many years have no place in Beijing at this time, how desolate it is. And those low-ranking officials are even more miserable, their salaries are not high, but they still spend a lot of money to rent a house to live, every time they think of their birth and death with me, but they can go to the evening and desolate, and they don't even have a property. Once they become officials, they can only return to their hometowns for retirement. Zhao Yu said sadly.

"It turns out that Your Majesty wants to use the vacated land to build houses for his vassals, so that everyone has a place to live!" Zhou Xiang was surprised when he heard this, and his heart was even more moved. In fact, he also understood that what the little emperor said was nothing new, but it had not been well resolved in previous dynasties.

Although the salaries of officials in the Song Dynasty were relatively high, the city was heavily populated, there were many people and few places, and the housing occupancy rate was not high, so many citizens had to rent houses. In the early years of the Northern Song Dynasty, even the prime minister lived in a rented house, and Han Qi, the prime minister of the Renzong Dynasty, said: "Since the government ministers, they live in the private houses of the officials in Beijing, and they abound. Zhu Xi also said: "And like the ancestral dynasty, all officials have no house to live in, although they are also rented." Even the prime minister is no exception, as the prime minister Kou Zhun once lamented: "After 40 years of wealth and nobility, there is no pastoral residence, and if you enter the palace, you will live in a monk's house or a residence." He is also known as the prime minister of "building without land".

It was not until the time of Shenzong that the imperial court allocated funds to build a number of official residences in front of the right gate of the Bianliang Imperial City: "The edict built four in the east and west mansions, the first one in the east mansion is one hundred and fifty-six, and the rest is one hundred and fifty-three each." The Eastern Mansion ordered the ministers to participate in the governor's affairs; Xifu ordered the privy envoy and deputy envoy to live there. …… The beginning of the move also, the deputy envoy of the three divisions, and the knowledge of miscellaneous imperial history are all predetermined. "In these official residences, only the prime ministers, governors, privy envoys, privy deputy envoys, three envoys, deputy envoys of the three divisions, Zhongcheng of the imperial history, and Zhiza imperial history are eligible to live in these official residences. Officials below the ministerial level are still "living in a house" and have not completely solved the problem.

Lin'an residents also rent more houses, but most of the officials rent public housing provided by the government, so that government officials live in the private residences of Beijing officials, and they abound. Due to the strong demand for rent, the rental market has been very hot, and if you have a decent property for rent, you will basically have no worries about food and clothing, which is exactly what you can do for three generations.

"Exactly!" Zhao Yu said.

"Your Majesty, forgive your subordinates for being unreasonable." Zhou Xiang was silent for a moment and saluted, "If Your Majesty provides a place to live for every official in the DPRK and China, his subordinates think that although it is good, it is difficult to achieve, and if it is not good, it will make the ministers dissatisfied. ”

"Oh, tell me about it!" Zhao Hao asked with some surprise.

"Your Majesty, land is scarce in Lin'an City, and it can be described as a land of every inch of land, and the city's Chinese military officials, large and small, there are thousands of people, how many houses must be built to meet the needs, and how many new officials go to work every year, and if the old officials leave Beijing, if they are all rewarded to individuals, I am afraid that the houses in the capital will not be enough." Zhou Xiang said, saw the little emperor nod, and continued.

"Colways: Shengmien, Doumien. If someone comes and has no house to give, won't it make people hate. Therefore, the subordinates thought that the old system was still followed, and the officials and lords who went to Beijing could be given houses to live in, but they had to be returned to the imperial court if they left office or died. In addition, a number of official houses can be built for many ministers to live in, and houses can be given according to grades, and monthly rent can be paid, which is cheaper than the market. Once they are transferred out of Beijing, or they are convicted, they must vacate their houses. ”

"How is this different from now?" Zhao Yu frowned, he meant to give the house as a reward to those officials who had made special achievements for the restoration of the country, not just to provide them with temporary accommodation in Beijing.

"Your Majesty's intentions, your subordinates understand!" Zhou Xiang smiled and said, "My subordinates thought that they could build another batch of mansions, which were nominally sold to ministers and large households, as long as there was enough money, they could be purchased, and Your Majesty could also be used as a reward for meritorious officials like subordinates." Those who dislike the simplicity of public housing, but do not lack money, can go and buy it, and those who have no money also have their own public housing to rent, and no one will complain, and will be grateful for His Majesty's mercy. ”

"This is a good proposal, after it is completed, I will reward you with a set first!" Zhao Hao smiled.

In fact, he also heard that this would not only reduce the resistance from the DPRK and China, because it was a matter for the benefit of all officials, and whoever opposed it would not become a public enemy, and greatly reduced his own pressure; Moreover, this is similar to the modern market economy, where the government only provides affordable housing, and individual needs can be adjusted through the market, although this is not complete; In addition, let him reward all his favors, firstly, he is weak, and secondly, as he said, everyone is the same, and there is no difference, and he will still be called unfair.

"Your Majesty, your subordinates thank you in advance!" Zhou Xiang got up and gave a big salute again.

"Hehe, you have left my house. But with your merits, how can it be beyond the reach of a house! Zhao Yu pointed at him and laughed.

"Then I will reward my two houses!" Zhou Xiang stretched out two fingers and climbed along the pole with a smile.

"Oh, you're still kicking your nose in the face, but Lin'an is a place to live for a long time, and when we recover the Central Plains and set up a new capital, I will reward you with a big mansion!" Zhao Hao opened his arms and scolded with a smile.

"Okay, the subordinates are serious, and they will ask for it at that time, Your Majesty can't rely on the debt!" Zhou Xiang saluted again.

"Okay, let's high-five and swear, I will never pay the bill!" Zhao Yu stretched out his hand and high-fived each other.

"Your Majesty, my subordinates think that it is not appropriate to just build a house for the courtiers, and they need to provide some cheapness for the poor people, reduce or reduce some rent or tax, in order to show Your Majesty's benevolence!" Zhou Xiang didn't expect that he would get a house so easily, and what surprised him even more was that he didn't expect that he would have such a high status in the emperor's heart, and he was moved in his heart. But I remembered something again, and put away the joke.

"And what is this?" Zhao Yu already felt that he had gradually understood all kinds of tricks in this era, but he didn't expect that there were still many things that he understood, so he frowned and asked again......
