Li Jingxuan's face immediately became embarrassed.

After Li Wei asked, he felt regretful. This matter could only be understood, not expressed in words, and it was not good to point it out. But it could not be explained. The more he explained, the less he could not get out of the stage. He immediately changed the topic and said, "I must let go. In the name of a good merchant, I only let a few people go, and everyone was dissatisfied."

But when I think about another thing, I don’t know a lot of famous families in the Tang Dynasty, and the most famous ones were the five surnames and seven families. These families were huge in power, with more talents and a wide area. Some big families could occupy tens of thousands of hectares of land. It is not said that every child of the aristocratic family lived a life of luxury and food. The family was large and the population was large. Except for a few real direct disciples, most of the children were just that. However, because of the many talents and books in the family, they could receive better education than the poor. In addition to these land, there were also some industries, such as Li, Fanyang Lu, Qinghe Cui, Boling Cui, Xingyang Zheng, Zhangshui, Yongjiqu, Yellow River, Jishui, etc., and they could also be involved in the canal transportation. However, the Wang family in Taiyuan and the Li family in Longxi were not related to the canal transportation.

This is also very important. The two Li Lis in Longxi are the most expensive, and the two Cui Boling are the most expensive. However, later, Cui and Li Zhaozhou gradually became more popular. It was precisely because of the economic impact of this water transportation on the family. But it was not without industries, such as the smuggling and trade with the Turks, the animal husbandry in Longxi, and the transactions with the Hu people. However, the two families themselves would not come forward. Even the Li family in Longxi became interested, and Li Wei just laughed.

It cannot be revealed, and he said: "After all, the risk at sea is high. When we arrive at the local area, many natives are ungrateful and conflicts are frequent. When driving boats and protecting safety, we have to release many people on each ship. Tang Lu refused to let the people go abroad, which is a failure. If they put too much, it would not be great. Therefore, I had an idea, and put a little pressure on them, and then put a batch of places, which is the last batch, and I can't put it any more."

"Dianzi said this very much."

Actually, this is not what I think, but if I release it, the more controversy it will sound, and the thoughts will not be reversed. In fact, there are many risks in navigation. For example, last year, although most ships came back safely, several ships had accidents. There was an accident at sea, and it was difficult for people on the ship to have hope of escaping. Li Wei even wanted to invent a life jacket, but there was no foam sponge, and could not find other practical substances with smaller density to replace it, so he had to give up. In fact, with the life jacket, the ship sinks, and most of it still cannot survive. In addition, Quanzhou's ship technology has just absorbed the Dashi and the South China Sea ship technology. It is built, but it is only very different from other people's ship technology and is not ahead. Therefore, it is not the time to fully release the ban on sea.

Since it is released too little, strange goods will definitely be there.

Li Jingxuan asked carefully again: "Then, your highness, how many families are you planning to release to sea?"

It’s also helpless. If someone asks someone to ask for a question, he has to give a correct sound.

"Not too many, one hundred to one hundred and fifty families. As for how many, the orphans and ignorant, it's up to you, my husbands." Old Lizi was not too bad. This time he also held his neck straight and tried his best to protect himself. So he had to repay him.

"Your Highness is very true," Li Jingxuan said again. He felt a little guilty.

"In fact, as long as you control the quantity and put it a little, it will also be beneficial to the country. In addition to the Tang Dynasty, there were many countries, such as the countries of India, Dashi, and Dashi west. Wherever the weather was hot, or if you went to land, you would walk two or three hundred miles away, and there was a sea called the Mediterranean. There was a land north of the Mediterranean, called Europe, and many countries. The population of these countries was only much larger than that of our Tang Dynasty. Many countries had been civilized. There were more ships to go to sea and tariffs increased. First, there were a few industries, such as sugar and firecrackers, which had taxes. If you sold more, the country could also increase its income. Second, there were also porcelain, bamboo paper, and the court also had many official kilns or official paper workshops, which could also increase its income. Third, even if it had nothing to do with the court, it would have to be built more. The people in the countryside made a living by farming, but the people in the city still made a living by craftsmanship. This is the fourth."

This also needs to be deliberately explained. You cannot just see some seeming disadvantages, nor can you say that the ministers are all pedantic people. The higher you reach the upper level, the less pedantic ministers will be, otherwise you will not be able to climb up. However, if you talk about power and ingenuity, these ministers are far above you, but when you talk about economy, most of them don’t understand. Some people even think that gentlemen do not speak of profit and navigation is a new thing. In fact, there are many benefits. If you don’t point out, these big guys may not be able to remember them.

Sure enough, Li Jingxuan began to ponder.

I don’t know much, but I know some, such as Byzantium, or Eastern Rome, or Great Qin. Anyway, there is a bit of chaos. There is another country in Northern Myanmar and Bangladesh in the south, also called Great Qin. I know that there are many people far away in the West, tens of thousands of miles away. Civilization may be behind China, but not much behind.

Navigation also has benefits. This is what I see. I don’t understand what it is to drive the country’s economy. In fact, the best example is that only the Southern Song Dynasty did the best in ancient and modern times, and tariffs accounted for one-six or seventh of the country’s economy. In addition, the indirect pull has driven more than one-third of the country’s economy. Therefore, the Southern Song Dynasty is in a corner, but the total economic output may be five or six times that of the Tang Dynasty. But the benefits of tariffs are actually seen. Now there are only one hundred households, and these hundred households are not ready and have a considerable income. If there are two hundred households and three hundred households, how many tariffs will be imagined. After the two channels, these incomes will belong to the court. The financial pressure on the court will be relieved a lot.

However, I didn't expect so many benefits, and I was also thinking about the disadvantages. If the national laws and let the people go abroad, the risk of being at sea will be high, and many people will die. I am encouraging the people to do business. The gains and losses cannot be evaluated.

Li Wei said again: "Gong-Dungeon Li, the court's income has increased in recent years. If you want to benefit the people, should you abolish the government's money?"

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

After the private release, the court releases it, and there are also arrests and officials to manage it. When the people fall in, they must destroy their families. If they are conscientious, the interest rate for a year is 300%, and those who do not care about their conscience are forced to lose their fortunes and refuse to give up. In some places, the people are unwilling to borrow, so they ordered the government to impose it on the people. Although the number is small, the people who are caught suffer a lot.

"I want to discuss this with other husbands."

It’s not a small amount, and there is a profit of more than 100,000 yuan a year. All officials are counting on it at the end of the year. Li Jingxuan dared not take the initiative.

The order to prohibit the people from going out to sea again was issued. Of course, many people became more anxious this time. Although they were dissatisfied with the prince's approach of using money as a good thing, it was still a chance. If it was banned completely, it would be useless even if there was more money to spend. Or going out to sea without permission was not a long-term plan. Therefore, many wealthy merchants wrote letters saying that the court was unfair.

At this time, Li Wei arrived at Caoqiao Pass.

July is about to end, and the two canals will start construction again. However, the center of gravity is shifted to the Danshui Canal. Renmen River is just for the purpose of draining the flow. It is best to be able to dig deep and wide. It does not require neat navigation, so the task is easier. However, when Danshui Canal reaches Caoqiao Pass, the task begins to be heavy.

Yao Shu came over, one step ahead of Li Wei, and two others were transferred from Longmen. The harvest was completed the year before yesterday and the cotton made contributions. So Wu Zetian took out 20,000 yuan of powder money from the inner palace and asked Wei Hongji to command it. Fan Yuanze, the supervisor of the east side of the Shangzhu Kingdom, as the deputy envoy. Shandao, a monk from the Pure Land Sect, and Huixia, the Huixia inspector of Chang'an, built a group of large cliff statues in Fengxian Temple on the hillside of the southern mountain in Longmen. There were eleven stone statues in total. The largest Lushenan reward Buddha was more than 17 meters high. The four were only responsible for command and supervision. The main project was the responsibility of the material craftsman Li Junzan, Cheng Renwei and Yao Shiji. The project was not over yet. However, Wei Hongji saw that the material craftsman Li Junzan and Cheng Renwei were proficient in the stone opening, and then thought that the Danshui project was beginning to be re-established, so he transferred the two people to the scene.

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

Yao Shuo took Li Wei to a cliff and said, "Your Highness, it's a bit bad. The groundwater is too heavy."

The project is clear, but when it comes to dry water, the water flow is very small since Caoqiao Pass. The water flow in Zhulin Pass is dangerous and rapid. Once it reaches dry water, there is no water, and there is no power. Therefore, the original plan was to block the river from halfway. The average river water was only one meter deep, unlike the Yellow River. No one has measured how deep the bottom is. The river water is deep, wide and urgent. Even if there are three or four meters deep in some places, it can be bypassed. I didn’t plan to navigate a ship with a 100 to 200 tons, as long as it can navigate a seventy or eighty tonnes during dry water.

The installed flat-bottomed ship is enough. This requirement is only one meter enough. In fact, just intercept the river water and chisel the uneven places to level, you can meet this requirement. Except for a few areas that are too shallow and need to be thrown away, the water depths can even be measured by a ship. There are no prominent beaches and reefs, so you can not repair them. Or you can see a little widening in the narrow place. Either prevent landslides on both sides, but they are rare in the middle, mainly because of the upstream, the mountains are soft and digging deeper, and landslides will occur.

The engineering is large, but it can be overcome. Moreover, most stone beds are not hard and are easy to dig.

However, this groundwater will have a headache.

Li Wei understood this. Geology is called rock veins. It seems that mountains are physical, but in fact, it is not the case. Due to the geology, many mountains are hollow, and large, forming caves and underground rivers. Some caves reach the ground outside the surface, called bright caves, and some reach the rivers and seas, and cannot be seen, and they are called dark caves. Underground rivers also have big and small, and the small ones cannot even catch up with the trickle mountain streams, and the big ones rush as far as some cha rivers in the water of Weifen.

This is a large, small but very small gap. Some can see it with the naked eye, while others cannot see it with the naked eye. Just like the capillaries on a human body, these water nourishes the grass and trees on the mountain, and the roots of the plants can in turn fix the water source. This cycle forms the vitality of the mountains.

In fact, in addition to the mountains, there are also other places, such as deserts, or more soil. Just like the Renmen Peninsula, there are also small amounts of water, and there is not much water. It is watering and rocks, and the river water leaking from the dam, which is ignored.

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

It had already risen, Yao Shu ordered again to ask the guards to drain the water with the water truck, and then said, "Your Highness, look."

Many water droplets immediately emerged from the river beach, gathering drop by drop, and then flowing to the lower place.

Li Junzan said: "Your Highness, this is pretty good. When I came here, I repeatedly measured the flow of the river. I saw that there were many rivers that did not gather, but the flow of the river was increasing. Not only was the water from the mountain, but I also suspected that there was an underground river reaching the river. If it was deep, I could avoid the passing. I was afraid that the underground river cave would be shallow and had to be dug, and the project would become difficult. Or you can look at it again."

As he said that, he took him to the foot of the mountain by the other river. A mountain stream flowed slowly down and went up the mountain stream. Li Junzan pointed to a rock and said, "Your Highness, look below the stone."

There is a small hole under the stone. It is not big and mostly hollow. There is a stream flowing out from the cave below. This is the so-called underground river. If it is a powerful **, it is not time to flow down, just like a stone blowing up the flat stone, and the civilians immediately pick out the gravel to solve the battle. But the current method of opening stones is still very backward, such as a cannon hammer, drilling holes of the drilling rig, gunpowder bombing, burning stones to stimulate water, or pouring vinegar to soften it. The gunpowder can be blown, but it really doesn't work. Put a mud bag under it. Before the water spreads up, it explodes. But there is no way to burn the stones again.

After looking at the lush and turbulent mountains, at least the greening is better than that of later generations, which also means that the groundwater source is richer than that of later generations. Li Wei frowned and said, "It's a negligence."
