Hand over the jade seal first [Infrastructure]

Xiao Xuan almost doubted his ears.

Did he hear correctly?Whole city floor heating supply?

If someone said this, he would definitely feel that the other party was talking nonsense, even Jiankang couldn't do this, Taoyuan City... how could Taoyuan City be possible?

Not only Xiao Xuan, but even Xiao Ji was attracted, and couldn't help asking: "The whole city? Those houses where no one lives?"

Xiao Zirong explained: "Every house has an earth dragon switch, and only the city government has a key to open that switch. If there is no one living in the house, the switch will be turned off, and those who cannot afford the floor heating fee will also be turned off. "

Oh, for a fee.

Only then did Xiao Xuan slow down a bit, but... this matter is still outrageous, how did it happen?

Especially how did this thing circulate throughout the city?

Xiao Zirong was still prepared for this, so he directly asked someone to bring over the blueprint, and then gave Xiao Xuan a simple science popularization.

It is impossible to really let the other party understand, after all, it involves a lot of physics knowledge, Xiao Xuan's physics knowledge... I am afraid it is not as good as the little ladies in Taoyuan City.

Just let Xiao Xuan know that this can be done.

Xiao Xuan did understand a little bit, and he quickly grasped a key point - Xiao Zirong had already built all the relevant facilities when he first built Taoyuan City.

But today's Jiankang would be very troublesome if he wanted to add this.

In fact, Xiao Xuan was only curious about this at first, and had no idea of ​​building it in Jiankang at all. The basic construction of this thing requires money.

Xiao Xuan was a little worried when he thought of this: "You still give them subsidies?"

No wonder his nephew is so poor, a subsidy is a whole winter.

Xiao Zirong said: "The subsidy is actually just a statement. Except for the first winter when there is the cost of manpower and material resources added to the construction, the rest of the time is purely profitable, including the annual maintenance. The first three years of maintenance are government-owned. The library is responsible, and after that, each family is responsible within the scope of the city, and other facilities in the city are responsible for the city government."

Xiao Xuan was slightly taken aback: "Make money? Can this still make money?"

Xiao Zirong immediately calculated an account for him. He kept these figures in his heart. Although they may not be particularly accurate, they are not too close.

Xiao Xuan was very surprised when he saw the amount he calculated. He never expected that he could make a lot of money, or because Taoyuan City itself did not have many market transactions, all the income in winter was brought by the heating of the city.

After finishing the calculation, Xiao Zirong said: "The annual income is like this, but there are some things that need to be excluded. For example, these facilities have to be overhauled every five years. If there is a problem, they need to be replaced. This part should also be included in the cost. , but generally speaking... it is still making money, which means that the population of Taoyuan City is small, and the more the population, the more money it makes."

Xiao Xuan felt that he couldn't keep up with this idea: "Doesn't a large population consume a lot of firewood?"

Xiao Zirong nodded: "Yes, that is indeed the case, but I have had people calculate that the population of Taoyuan City has more than doubled compared with the present when the population was not large, but the firewood used has not been so much. It has increased by about [-]%, if there is more... Well, if the city is very large, two boilers need to be installed to ensure the water temperature, but since the water is already warm when it reaches the second boiler room, it will not cost too much to reheat firewood, so it should still be a good deal.”

In fact, at the beginning, Xiao Zirong just wanted everyone to live a better life, after all, he himself couldn't bear the winter in the south.

But he doesn't want to be too independent, letting others listen to him is just for the sake of future development, no matter what the situation is, he needs a leader to lead the way.

But he didn't feel in his heart that he was naturally superior to those little ladies, so he tried his best to be similar to everyone in life.

Of course, this kind of persistence is basically gone now, if Taoyuan City is not born, it’s fine, since it has been born, then his identity is there, no matter what he thinks, Xiao Xuexing can’t see that he is not good enough for food and clothing.

Xiao Xuan carefully looked at Xiao Zirong's analysis, and then asked: "If you are in Jiankang, what do you think we should do?"

Xiao Zirong hesitated for a moment: "Jiankang... the situation is too complicated, mainly because the earth dragons of each family are different, and it is not easy to link them together. If they are not connected, they need to be redone, which will cost too much money. big."

Xiao Xuan said: "Then if you were given a city about the size of Jiankang, what would you do?"

Xiao Zirong thought for a while and said honestly: "If there is nothing special, then I will lay half of the facilities in that city."

Xiao Xuan was a little surprised after hearing this: "Half? Why don't you care about the other half?"

Xiao Zirong looked at him and explained earnestly: "Compared to the current prices, the heating fee for a winter in Taoyuan City is actually not cheap. It will freeze to death, and some ordinary people may not pay this money, even if they get it, it will be a waste of effort.”

As for why it is half... In fact, this is because he expanded the scale. According to the actual situation, maybe one-third of the city is enough to lay.

No matter in what era, the poor are the majority, and those above the well-off level are few.

It’s just that people above the well-off level in ancient times can read and have the right to speak, so what later generations see is their living conditions. The real living conditions of ordinary people can only be inferred from archaeological artifacts and some clues in historical records.

Xiao Xuan nodded with great satisfaction: "Not bad."

Xiao Zirong was a little dazed, why was he so satisfied?

However, Xiao Xuan felt that Xiao Zirong's traits were very beautiful. At the beginning, he was worried that Xiao Zirong's vision was not wide enough when he grew up among the people, and his behavior was easy to be petty. There is also a long-term vision.

Very good.

After Xiao Xuan was relieved, he asked casually: "Then why did you get all of Taoyuan City?"

Xiao Xuan originally thought that Taoyuan City was not big, so it would not cost much to build it, but in the end, he heard Xiao Zirong say: "Because Taoyuan City has financial support, this is why I just assumed that there is no special situation in that city. , Taoyuan City...has salt."

Regarding the sale of salt in Taoyuan City, Xiao Zirong didn't intend to hide it from the beginning, or maybe Xiao Xuan already knew about it, but he just didn't have time to mention it.

In this case, it is better to go directly to Ming Road. Anyway, Taoyuan City can produce salt, so we can't let Taoyuan City demolish the salt factory, right?

Xiao Xuan was slightly taken aback after hearing this: "Oh, yes, salt." Xiao Xuan glanced at Xiao Zirong and asked wonderingly, "Why didn't you see the salt well when you looked at the sand table yesterday?"

The strangest thing is that there is a salt well here, so why didn't the Wen family find it here for so long?

The salt well didn't come into existence overnight, and the most important thing is that the vegetation around Taoyuan City is too lush. It is well known that it is impossible to have such lush vegetation around the salt well.

Xiao Zirong smiled mysteriously and said, "I have a special recipe, and I don't need a salt well."

No need for a salt well?Is it possible to change it out of thin air?

Xiao Xuan thought for a while and suddenly realized: "You boil the sea to get salt?"

Boil the sea... Okay, most people in this era who want to extract salt from the sea subconsciously use fire to burn the seawater, and the salt can be obtained by boiling the seawater dry.

Xiao Zirong thought about it seriously and said, "It's about the same."

When extracting salt here in Taoyuan City, the brine must be continuously heated, and the brine is also dried from the sea water, so the calculation is not too bad.

He said that he was so vague because he didn't want to hand over the formula. He asked Xiao Xuexing about this matter, and Xiao Xuexing said that he should not rush to hand it over now, but wait until the right time.

It's just that Xiao Zirong doesn't know when the timing is right, since Xiao Xuexing said so, then he will hide it.

Xiao Xuan didn't say anything, there are things like collecting firewood and cooking sea salt to get salt, but not many, no one does this for selling salt, usually ordinary people really can't afford salt, so they go hard to get some sea salt to eat, but Not too much, because the cost is too high.

Think about how much firewood it takes to boil the water dry, and the salt you get in the end is easy to eat dead people.

If you don't master the refining method, the salt boiled in seawater will contain heavy metals, and if you eat too much, you will easily get sick and die.

However, he recalled that his nephew just said that there is a special secret method, which presumably can control the cost, and so far, there are not too many trees on the mountains around Taoyuan City, which proves that they should not cut down many trees.

Xiao Xuan didn't ask any more questions, but hesitated a little. Salt...is under the control of the imperial court now, but Xiao Zirong has his own secret method, so it's very difficult to deal with.

Emotionally, Xiao Xuan wants Xiao Zirong to continue to operate.

There is no way, his nephew is miserable, he doesn't have much money, and finally got a business that makes money, and then what will his nephew eat and drink?

But intellectually, he knows that the Yantie official camp must be firmly held in his hands, and once a special case occurs, the government will be prone to turmoil.

Of course, the court has been trying its best to ban private salt, but it can't. Even Xiao Xuan can't do anything about it.

But the private salt is sneaky after all, and now everything in Xiao Zirong's Taoyuan City is on the bright side, which is a headache.

Xiao Xuan didn't want to talk about this, worried that Xiao Zirong would be sad if he said it, but he had to mention it.

On the contrary, Xiao Zirong asked very straightforwardly: "Uncle, where there is a salt well, how much is the tax paid to the court every year?"

After hearing this, Xiao Xuan immediately reflected, yes, as long as Taoyuan City pays the imperial court, it is enough. Originally, even if the imperial court is in charge of the salt wells in the whole country, it is also responsible for extracting, guarding and selling them locally, and then pays the money to the center in proportion to the sales amount.

Taoyuan City should also be like this, let Xiao Zirong still manage his salt well, and then just pay the money every year.

He hesitated for a while at this thought, but immediately said in a low voice: "Don't spread the fact that you have the secret method of salt making in your hands, and don't tell anyone who asks, understand?"

Xiao Zirong hesitated for a moment, this...is different from what he thought.
