This night belongs to Wu Zetian, no one fights with her, no one robs her, the efforts and hardships she has put in for this family, everyone can see it, although she usually doesn't say anything, but it is hidden in everyone's hearts.

This night, Wu Zetian has indulged himself in a rare way in the past few years and enjoyed his rights as a woman.

The next day, Li Zhonghua took Wu Zetian and the women who had just come from Chang'an to visit Jinzhou, which was under construction.

The planned industrial park is being built with cement at this time.

Wu Zetian and the others, looking at the cement pavement that had been repaired, were very flat and clean. Walking on the concrete pavement, it feels very hard and strong, and it is very safe and comfortable.

"Master, how did you build this road? It feels good, and if it's raining, you won't get your shoes wet, so it's so convenient. ”

After all these years of experience, Wu Zetian's vision has been very shrewd, and he immediately realized the business opportunities hidden in it.

"This thing is called cement, which is used to build roads, which is really good, and it can also be used to build houses and city walls, and it is still very useful." Li Zhonghua said with a smile.

"Cement? The cost of making this thing is not large, if it is used to build a cement road from the imperial capital Chang'an to the eastern capital Luoyang, it must be very good.

Sitting in a carriage and walking on such a flat concrete pavement, at least there will be no bumpy feeling, it should be very comfortable, and the speed should be much faster. Wu Zetian said on a whim.

"Although the cost is not very high, but the amount of use, plus manpower and material resources, as well as transportation, the cost will be very considerable, want to build a cement road from Chang'an, straight to the eastern capital of Luoyang, the cost will be very amazing."

Although cement is not expensive, but the demand is very large, so the cost of construction is not small, and the cost of building a cement road in later generations is very high, even if it is an ordinary road at the rural level.

However, the cement roads built in later generations will be of high quality because they have to withstand the pressure of heavy trucks, and they are basically made of reinforced concrete.

But if it is placed in the era of the Tang Dynasty, it must be much simpler to build a cement road from Chang'an to Luoyang.

At this time, the most run is the carriage, the load capacity is not large at all, there will be no damage to the road surface, no need to use any steel bars, in fact, in this era, it is impossible to have steel bars for you to use, so the cost will be much cheaper than later generations.

The biggest cost is actually the cost of transportation.

To solve this problem, the best way is, of course, to build a cement processing plant every other distance, only in this way can the cost of transporting cement be reduced to the greatest extent.

The production of cement is very simple, as long as there is limestone and clay, you can build a cement factory, and produce cement, the process and burnt lime are similar.

Limestone is very hard, and in this era, there is neither electricity nor mechanical equipment, and it is impossible to crush limestone, prepare it into raw meal, and then calcine.

Therefore, it can only be calcined first, the clinker is directly crushed, and then they are configured according to a certain proportion.

Compared with raw meal, hard limestone, after calcining mature material, is much easier to crush.

"Forget it! If the cost is very large, the imperial court will definitely not consider it, and His Majesty will not agree to it, and His Majesty is very stingy with any project that costs a lot of money. However, on the main streets in the imperial city, there should be no problem with using cement to build roads.

The concubine went to Chang'an, found someone to come over to learn how to make cement, and asked them to go back to Chang'an to set up a cement factory, which should be able to make a little money. ”

As soon as she thought of making money, Wu Zetian immediately became excited, as long as it was a business that could make money, she didn't want to let it go.

"Huh! On this road from Chang'an to Luoyang, there are many merchants and pedestrians, almost day and night, if the imperial court is not willing to pay for the construction of this official road, we can build one ourselves! Play a re-play to draw a route, try to take a straight line, open the road in the mountains, and build bridges in the water. Li Zhonghua said very casually.

Then there is private investment in road construction, which is a normal thing, and it is a very profitable business.

"What? We spend our own money to build roads, sir, are you confused again, how can there be such a thing in the world, private people help the court build roads, this is not a very short road. Wu Zetian said in surprise.

Wu Zetian now regrets that he has nothing to do, saying that he is talking about repairing the cement road from Chang'an to Luoyang, and the old man suddenly became nervous, and he actually wanted to pay for this road by himself.

She suddenly felt as if the money in her pocket was about to fly away.

"Your master didn't make any mistakes, no, what did your master make any mistakes again, when did your master let go of the confusion?" Li Zhonghua was really a little depressed,

"Forget it, Master Ben doesn't care about you anymore, in fact, building this road, although it can also be said that it is to help the court build this road, but this road is also for us to repair ourselves, but not only will he not let us lose money, but he may even make money, and he will make a lot of money."

"What the master said, the concubine can't understand it, do the sisters understand? The lord actually said that if we pay for the road by ourselves, not only will we not lose money, but we will also make a lot of money. Wu Zetian laughed exaggeratedly.

"My sister didn't understand, how can we sisters understand, we don't understand business things.

But since the master said this, there must be a reason for him, my sister might as well wait for the master to finish speaking, won't she understand everything? Yang Xue said with a slight smile.

These words not only praised Wu Zetian, but also helped Li Zhonghua speak, who dares to say that Yang Xue is a scheming person, but her character does not like to be competitive, and she does not like to offend people when she speaks.

So she, the eldest sister, is also speechless, and she has a tolerant attitude towards everyone, neither partiality nor bias, no matter who she is, she is an inclusive attitude.

"After this small dirt road is repaired, we have to collect tolls, and of course it is not mandatory for everyone to take this road, so this road needs to be built separately and the route is also planned separately.

People who don't want to spend tolls can still take the old road, which has nothing to do with us, but if you want to take the cement road we built, then you have to pay the toll.

However, the officials and soldiers of the imperial court can pass for free, and to build this road, we must also obtain the approval of the imperial court, and we must also be approved by the imperial court to collect fees, so that we can build such a cement road.

With the approval of the imperial court, we collect tolls, which is reasonable and legal, and anyone has nothing to say, without the approval of the imperial court, of course, we have no right to collect tolls from passers-by. Do you understand what I mean? Li Zhonghua asked after explaining.

"I understand it, the key is that the imperial court will approve it? And how much is the standard for charging at one time? When will the cost of this road be recouped? ”

Wu Zetian said with some skepticism, but the questions raised all showed her characteristics as a strong woman, and she was very shrewd.
