Li Jingxuan's face immediately became embarrassed.

After Li Wei asked, he also regretted it, this matter can only be understood, not spoken, and it is not good to break it. But it can't be explained, and the more it is explained, the more Li Jingxuan can't get off the stage. immediately diverted the topic and said: "If you put it, it will definitely be released, in the name of good businessmen, only a few people will be released, and everyone will not be convinced." ”

But in my heart, I thought about another thing, the famous families of the Tang Dynasty did not know how many, the most famous were the five surnames and seven families, these families were huge, not to mention the talents, and the area was also very wide, and some big families could occupy tens of thousands of hectares of land. It can't be said that every child of the family lives a life of fine clothes and food. The family is large and the population is large, except for a few real descendants, most of the children are like that, but because the family has many talents and a large collection of books, they can receive a better education than the poor people. In addition to these fields, there are also some industries, such as Zhaozhou Li, Fanyang Lu, Qinghe Cui, Boling Cui, Xingyang Zheng, Zhangshui, Yongji Canal, Yellow River, Jishui, etc., and can also be stained with Caoyun. However, the Taiyuan Wang family and the Longxi Li family and Cao Yun have no relationship with each other.

This is also very important, the two Li Longxi Li are the most expensive, and the two Cui Boling Cui are expensive, but later Qinghe Cui and Zhaozhou Li gradually have a tendency to catch up, precisely because of the economic impact of this water transportation on the family. But it is not that there is no industry, such as the smuggling trade in Taiyuan, and some smuggling trade with the Turks. Pastoral farming in Longxi, as well as trading with the Hu people. However, the two families themselves will not come forward. Even the Li family in Longxi was interested, and Li Wei just laughed in his heart.

can't be exposed, and said: "After all, the sea is risky, that is, when you get to the local area, there are many indigenous people who don't know what to do, and there are conflicts from time to time. To operate the boat and protect the safety, each ship has to release a lot of manpower. And Tang Law does not let the people go abroad, this is already an exception, if you put too much, it is not very good. Therefore, Lone has an idea, press it a little, and then put a batch of places, which is also the last batch, and can not be put again. ”

"The palace is very right."

In fact, I don't think so, but if you put it too much, there will be more controversy, and the thinking has not been reversed, in fact, there are many risks in navigation, for example, last year, although most of the ships came back safely, but there were also a few accidents on the ships. In the event of an accident at sea, it is difficult for the people on board to have any hope of escape. Li Wei even wanted to invent a life jacket, but there was no foam sponge, and he couldn't find other practical materials with a lower density to replace them, so he had to give up. In fact, with life jackets, the ship sank, and most of them still couldn't survive. In addition, Quanzhou's ship technology has just absorbed the technology of Dashi and the South China Sea, and it is under construction, but it is only about the same as other people's ship technology, and there is no lead. Therefore, it is not yet the time to fully release the ban on the sea.

Since there is less of it, the odd goods will inevitably live.

Li Jingxuan asked cautiously again: "Then Your Highness, according to your wishes, how many families do you plan to release to the sea?" ”

is also helpless, people ask someone to ask, and they have to give a quasi-tone.

"Not more, a hundred to a hundred and fifty households. As for how much, the lonely young and ignorant, it is still up to you to decide. "Lao Li Zi is not too bad, this time he also held his neck and tried his best to protect himself. So repay the favor.

"What His Highness said is extremely true," Li Jingxuan said again. I feel a little weak.

"In fact, as long as the number is controlled, a little put, it is also good for the country, outside the Tang Dynasty, there are many countries, such as Tianzhu countries, big food, big food west and countries, where the weather is hot, or on the land, walking two or three hundred miles, and there is the sea, called the Mediterranean, there is a land north of the Mediterranean, called Europa, and there are many countries, the population of these countries combined, only a lot more than our Tang Dynasty, there are many countries have been civilized. First, there are a few industries, such as sugar and firecrackers, which are already taxed, and if they are sold more, the country can also increase its revenue. There are also porcelain and bamboo paper, and there are many official kilns or official paper workshops in the imperial court, which can also increase income. Third. Even if it has nothing to do with the imperial court, the more it sells, the more it will be made, and the people in the countryside farm to make a living, but the people in the city still rely on their crafts to eat. This is the fourth. ”

This must also be deliberately explained, not only to see some seemingly bad points, nor to say that ministers are all broad people, the higher they go, the more the ministers will not be broad, otherwise they will not want to climb up. However, if you talk about the art of power and strategy, these ministers are far above themselves, but when it comes to the economy, most of them don't understand, and even some people really think that gentlemen don't talk about profits, and navigation is a new thing, in fact, there are many benefits, if you don't point it out, these bigwigs may not be able to think of it.

Sure enough, Li Jingxuan began to ponder.

I don't know much, but I know some, such as Byzantium, or called Eastern Rome, or called Daqin, anyway, there is a bit of chaos, and there is a country in North Burma and Bangladesh in the south that is also called Daqin. Knowing that far away in the West, tens of thousands of miles away, there are many people, and it is possible for civilization to lag behind China, but not by much.

There are also benefits to navigation, which is seen, what pulls the country's economy, do not understand. In fact, the best example, in ancient and modern times, only the Southern Song Dynasty did the best, with tariffs accounting for one-sixth or seven-part of the country, plus indirect pull to stimulate more than one-third of the country's economy. Therefore, the Southern Song Dynasty was in a corner of peace, but the total economic volume may be five or six times that of the Tang Dynasty. But the benefits of the tariff are really visible, and now only 100 households have been released, that is, these 100 households are not ready, and they already have considerable income. If it is two hundred or three hundred households, it is still conceivable how many tariffs there will be. After the two canals, these revenues will go to the imperial court. The financial pressure on the imperial court will be eased a lot.

However, I didn't think of so many benefits, and I was also thinking about the disadvantages in my heart, overstepping the national law, letting the people go abroad, the sea risk was great, many people would die, and how much was encouraging the people to do business. The gains and losses cannot be discussed.

Li Wei said again: "Li Xianggong, in recent years, the income of the imperial court has increased, and if you want to benefit the people, do you want to abolish the public money." ”

To be honest, after looking at it over the years, Li Wei is not too dissatisfied with all kinds of things in the Tang Dynasty, after all, in this era, such science and technology, such productivity, and such understanding, it is not easy to achieve this point, but he hates this public money the most.

The private people are released, the court is released, and there are arresting officials to manage it, and the people fall in, and they have to be ruined. Those who speak of conscience will have an interest rate of 30 percent a year, and those who do not have a conscience will be 300 percent. In some places, the people were unwilling to borrow it, so they ordered the government to impose it on the people. Although the number is not large, the people who are recruited are miserable.

"I'm going to discuss this with other ministers."

It's not a lack of money, there are hundreds of thousands of dollars a year, and all officials are counting on it for year-end bonuses. Li Jingxuan alone did not dare to call the shots.

The order forbidding the people to go to sea again was issued, and of course, many people were even more anxious at this time. Although he is dissatisfied with the prince's practice of taking money as a good thing, it is still more or less an opportunity, if it is completely banned, it is useless to spend more money. Or going to sea without permission is not a long-term solution. As a result, there were many wealthy merchants who wrote to the court that it was unfair.

At this time, Li Wei arrived at Caoqiao Pass.

As July draws to a close, the construction of the two canals will begin again. But the center of gravity has shifted to the Danshui Canal, and the Renmen River is just for drainage, and it is best to dig deep and wide, not to seek neat navigation, and the task is easier. However, when the Danshui Canal reached Caoqiao Pass, the task was heavy.

Yao Xuan greeted him, one step ahead of Li Wei, and there were two other people who were transferred from Longmen. The harvest of the year before last was good, and the cotton made a contribution, so Wu Zetian took out 20,000 fat powder money from the inner palace, let Wei Hongji command, and Fan Yuan, the superintendent of the east of Shangzhu State, was the deputy envoy, and the Pure Land Sect monk Shandao and Chang'an Fahai Temple Hui Xuan inspected the school, and built a group of Fengxian Temple cliff statue shrines on the southern mountainside of Longmen West Mountain, a total of 11 stone statues, and the largest Lushena Buddha is more than 17 meters high. The four of them are only responsible for command and supervision, and the main projects are still in charge of the material craftsmen Li Junzan, Cheng Renwei, and Yao Shiji. The project is not over yet. However, Wei Hongji saw that Li Junzan, a branch craftsman, and Cheng Renwei's proficiency in Kaishi, and thought that the Danshui project was starting to be heavy, so he transferred these two people to the room.

However, as soon as the two of them came over, they immediately saw a problem.

Yao Xuan took Li Wei to the edge of a cliff and said, "Your Highness, something is not good, the groundwater is too heavy. ”

The scale of the project is clear, but in the dry season, since the closure of the grass bridge, the water flow is very small. It is that the water flow in the area of Zhulinguan is dangerous, and when the water is dry, there is no water, and there is no power. Therefore, the original plan was to block the river, the average river water is only one meter deep, not like the Yellow River, how deep the bottom is, no one has measured, the river is deep, wide and urgent, even if there are places will be three or four meters deep, you can also bypass. It was not intended to be a ship of 100 tons or 200 tons, as long as it could be navigated by a 70 or 80 ton converted flat-bottomed ship when the water was dry. This requirement is also only one meter sufficient. In fact, as long as the river water is intercepted and the uneven places are chiseled flat, this requirement can be achieved. Except for a few sections that are too shallow and need to be chiseled, the water depth is even measured by boats, and there are no protruding beaches and reefs, which can be left unrepaired. Or if it's too narrow, you can't see it a little wider. Either to prevent landslides on both sides, but it is rare in the middle reaches, mainly in the upstream, the mountains are soft, and they are dug deep, and there will be landslides.

The project is large, but it can be overcome. Moreover, most of the stone layers are not hard and easy to excavate.

However, this groundwater will be a bit of a headache.

This Li Wei understands, and it is called a rock vein in geology. It seems that the mountains are solid, but in fact, because of the creation of geology, many mountains are hollow, big holes, into underground rivers, some holes reach the ground outside the surface, called open holes, and some reach the bottom of rivers and seas, which cannot be seen, and are called dark holes. There are also large and small underground rivers, the small ones can't even catch up with the trickling mountain streams, and the big ones are no less than some forked rivers in the water of Weifen.

It's big, but it's small, but it's made up of tiny gaps, some of which can be seen with the naked eye, and some of which can't be seen with the naked eye, just like the capillaries of a human body, which nourish the plants and trees on the mountain, and the roots of the plants and trees in turn fix the source of water. This cycle is what makes up the vitality of the mountain.

In fact, in addition to mountains, there are other places, such as deserts, or more mud. Just like the Renmen Peninsula, there are also them, but there is not much water. It's the watering of the rocks, and the river water leaking from the dike, all of which are overlooked.

After Yao Xuan finished speaking, he took Li Wei and walked around the two stacked mountains to the river. This section of the river is relatively wide, and behind it are several mountains with good trees, and Yao Xuan asked people to build a dam here to observe the amount of groundwater.

It was already full, and Yao Xuan ordered again to let the guards drain the water with a water wheel, and then said, "Your Highness, look. ”

Immediately from the river beach, many droplets of water flowed out, gathered drop by drop, and then flowed lower.

Li Junzan said: "Your Highness, this is not bad, the minister came here, repeatedly measured the flow of the river, and saw that there are many places where the river water does not flow together, but the flow of the river is increasing. Not only the water that flows out of the mountain, but also the minister suspects that there is an underground river that leads to the river. If it is deep, it can be avoided in the past, but I am afraid that the underground river hole is very shallow, and it must be excavated, and the project becomes difficult. Or your Highness will come and see again. ”

As he spoke, he took another mountain to the foot of another river, where a mountain stream slowly flowed down, and along the mountain stream, Li Junzan pointed to a rock and said, "Your Highness, look under the stone." ”

There was a small hole under the stone, which was not large, but most of it was hollow, and a small stream flowed from the hole below. It's called an underground river. If there is a powerful **, before it has time to flow down, it will be like a stone blowing flat, and the people will immediately pick out the gravel to solve the battle. However, the current method of opening stones is still very backward, such as cannon hammering, drilling rig drilling, gunpowder bombardment, burning stone and water, or pouring vinegar to soften. It's okay to blow up the gunpowder, but it's really not okay to put mud bags underneath, and the water has not spread up yet, so it explodes. But there is no way to burn the stone anymore.

Looking at the verdant Cui Wei mountain, at least the greening is better now than in later generations, which also means that the underground water source is richer than in later generations, Li Wei frowned and said, "It's a lonely negligence." ”

There is a theory, and it has also been turned around here, but without Li Cheng and the others reminding them, they didn't think of it, and they didn't find it.
