It is not easy to let the guards lift the iron pillar, and the iron pillar must be kept stable in order to make the cannon hammer hit it every time. Otherwise, if it misses all of a sudden, it will cause the steel column to collapse and even fall into the air, and even the bracket can be broken. But this is also simple, aim first, and then use a large ruler to set the size, the current guards, the future people, when you hold it up, you can match the size.

It's just more time-consuming, and it's also helpless. Backward technology has led to backward and laborious operation methods.

For some reason, there were many people watching, and gradually the iron pillar sank under the stone. Although the stone layer is hard, after all, it is only a stone, not a diamond. The hammer has also been improved again and again, and is more powerful than the original hammer. But it's still slow.

It's not about building a dam now, it's just experimenting with it, and then it's starting to be dialed up with a winch. Slower. And now it's just on the shore, it's much easier to operate, but once the dry season comes, it's more difficult to operate when it's gradually rammed into the door.

But it's probably the best way to do it right now.

Mainly the column and the dial column, the barbed wire can be arranged in advance, step by step with the iron pillar to the water discharge, and even want to save, the barbed wire can be re-untied when dialing the column. Or the water in Dan water is gentle, and hemp rope can be used instead.

Seeing that it took a lot of effort to pull up the iron pillar again, the people didn't know what was going on.

Only then did Li Wei give an order and began to erect a wooden sign on the edge of the Renmen Peninsula, with a rain eaves on top and a few large pieces of paper posted below, drawing the intention clearly. Post your ideas, and maybe people will come up with better ways to improve. At the same time, it is also to calm the hearts of the people.

But that's not all.

In addition to Xinkaihe, Li Wei finally revealed his true thoughts. This year is just a new river, and it is not easy to complete the construction smoothly. Next year, the Shenmen Island will open the river, and it is feasible to go from Renmen to Shenmen Island, after all, a large amount of manpower and materials are needed to be transported. This is followed by the Ghost Gate Peninsula. After careful study, it is precisely because the Guimen Peninsula is cut off in the middle of the river that the water flow of the Guimen Shenmen is biased to the northeast, and it is integrated with the Renmen water flow, and the water flow speed is accelerated, rushing straight to the pillar.

Open out the new river of the Guimen Peninsula, not for navigation, is to discharge part of the water flow, these three rivers open, the water potential will gradually flatten, and then from Shenmen Island to Guimen Island, and then dig a new river, all of which are mainly to discharge floods. Of course, if he has no ability, he has the ability to build a Sanmenxia dam and solve all problems, but as for whether it will be like the Nile Dam, which will block the sediment and have an impact on the upstream, Li Wei probably can't consider it. Even if you think about it, you don't have the ability to build it. Therefore, it is still possible to use the dredging method.

As soon as the four rivers opened, the water immediately became gentle. Will continue to use the slender man, but not as miserable as it is now.

It's not that it will become a paradise immediately, or there are no three gates, and the Yellow River is here, very steep and urgent, with seven bends and eight twists, and there will be accidents. But it will be better. Besides, who can guarantee that shipping will be 100% safe? Even on the Grand Canal, the current is relatively gentle, but there are accidents from time to time, when the wind and waves are strong, or the ships collide, or the quality of the ships themselves is hidden.

The intention was very good, but Wei Xuantong and Wei Siqian both gasped.

Wei Xuantong said: "Your Highness, this cost ......"

The brain is very good, but there is no way to calculate the cost.

Li Wei smiled and said, "Wei Changshi, don't underestimate Haishi. Besides, the year after next year, there may be a lot of income to spend next year. ”

Wei Xuantong suddenly believed and doubted, this is not a lack of money, like the controversial sale quota last year, the effect is also good, compared with the two canals, the raised finance is less than one-tenth. With the 200,000 yuan of the imperial court every year, it is estimated that it will be piled up in Sanmen for ten or eight years, but it will not be successful.

But it's somewhat credible.

When I arrived at Zhulin Pass, I saw the form of Danshui, and then calculated the project and difficulty, and I was also relieved in my heart. However, a wire mesh pocket immediately solved the problem of building a dam to block water. This cost is very high, many places have to need iron pillars, not one or two, maybe tens of thousands, hundreds of thousands, plus the cost of tamping and appropriation, the cost is huge, and even Wei Xuantong suspects that the imperial court does not have so much iron ore to smelt.

But if the iron pillar is not used once, it cannot be used again. Besides, if you don't need it, you can re-melt it and turn it into iron, which is also considered to be the cost of recovery. However, this method is used to solve the difficulty of blocking the dam in the rapid and deep water flow, and the same saving and vigorous labor is not a waste, but a saving.

Maybe the crown prince will come up with a new solution to the financial problem.

So Wei Xuantong was silent.

Of course, the common people did not know the specific situation, but they only saw that there was a way, as soon as the newly opened river was opened, the transportation would be convenient, and if the river was divided into a few more rivers and the water potential eased, there would be less forced labor in the future, and even fewer relatives would die, and they were very happy. And because of the increased difficulty of construction, the daily salary of recruiters has also increased from 50 to 55 yuan, so there is thunder.

But when the news reached the capital, all the officials were stammering.

Big, big!

Although the idea is good, where did the prince get this batch of expenses? Don't say that in the future, even this year's expenses will become a serious problem.

But another thing just as caught the attention of officials.

By September, more ships were returning. It was not very smooth, there were storms and waves at sea, and some people died in the sea because the ship sank, never to return. There are also uncivilized indigenous peoples, and conflicts occur from time to time. Behind is trouble, and there is not much to lose. After all, the Tang Dynasty emphasized martial arts and light literature, and the folk martial arts were also very prosperous, but they were not familiar with it, and the situation of fighting in the nest did not happen, and everyone was afraid of accidents when they went to sea, so they formed a large-scale fleet. Although there were few people on each ship, they all carried weapons, which were not comparable to those of the Japanese people. When encountering bad things, coupled with the mentality of a big country, do more things that harm the local area.

However, it is mainly a trade, and there are many good things in the Tang Dynasty, such as porcelain, lacquerware, paper, cloth and silk, tea, some spices and medicinal materials produced in the Central Plains, jade, and even Tang Sancai for funerals.

When he went to a foreign country, he went to exchange spices, precious stones, ivory, coral, pearls, and even in some ports in the South China Sea, he exchanged them for glassware produced by the Great Cannibals, as well as wool dumplings, and Persian brocade. There really isn't, such as the Wa Kingdom, then exchange gold, silver, copper, iron, or related ores. This is also good, the Tang Dynasty was severely lacking in metals, including iron. The simplest example is armor, although the Mingguang armor is good, not all soldiers can afford to wear it, and the imperial court can't control it. In addition, there are armor such as light, fine scales, mountain scripts, and black hammers, and even in order to save iron, they are replaced by net pocket armor and chain mail, and sometimes cloth armor, silk armor and wooden armor are used to fool around. One is the high cost, the second is the backward technology, and the third is that there is very little iron ore, which is used by the military and the people. Not to mention the value of gold, silver and copper, in addition to making utensils and jewelry, it can be used as currency. For example, a piece of cloth is only 300 yuan, but it weighs more, and it is exchanged for more than 300 copper coins, and the imperial court's Tongbao money is only 1.5 kilograms, and the people's illicit treasures are not enough for one kilogram. If it is exchanged for silver, it is only three pennies, and gold is tenths of a penny. It's not that they don't know the benefits of metal money, it is precisely because gold, silver and copper are insufficient and inconvenient to circulate, so cloth is used instead of trading.

I don't understand the language, and it's also a trouble. Most of the transactions are made by taking out three or four pots, taking a grain of jade from the other party's hand and pushing them in two. The indigenous people are just backward, after all, they are human beings and can understand. After all, it is not a safe way, there is no good communication, and there are many misunderstandings.

How much wealth and what strange things happened, the court doesn't talk about it, and has the ability to earn it by itself, but just relying on the latter point, many officials are speechless. With more metal, the benefits to the imperial court are all known. But even if you enter the port, that is, when you arrive at Suzhou Port, it will take at least half a year for the goods to be transferred to the capital. However, some businessmen have already let the steward ride to Chang'an on fast horses, buy the production around Chang'an, and go down the canal to trade with foreign countries. Of course, it is unlikely that a pot will be exchanged for an ivory, but the difference in price is very large, and a lot of money is made.

Finally, the merchants who had already obtained the quota in the two capitals finally couldn't sit still, and sent people south to Quanzhou one after another to discuss shipbuilding and hire sailors and boatmen. This incident also caused a sensation, but what made the official speechless was not only the metal that was brought, but also some indigenous chieftains, who came to the Tang Dynasty to bow down, and were very disdainful of this Li Wei, but it was valued by the feudal dynasties of previous dynasties. There was also brimstone, which had to be exchanged by merchants from abroad. How important sulfur is, even a seven-year-old boy in the capital knows it.

But it was still not as shocking as the prince's generosity.

When Wei Hongji heard this, he couldn't stay stunned, dragged his sick body, came to Sanmen, and when he saw Li Wei, he said, "Your Highness, no." ”

Originally, the project was to go to the sea and expand the three rivers......

Wei Hongji's head is big.

Li Wei smiled and said, "Whether it can be done or not is a fee." You'll see it right away. ”

How much you can get depends on Yao Xuan's lip service. Li Wei also has no bottom. But with the arrival of September, the autumn harvest is gradually over, and construction can already begin. So the people were recruited, and at the same time, a large number of materials were transported, including all kinds of cannon hammers, and even in Danshui, considering the special terrain, let the ship anchor at both ends, and use the ship's mast as a hammer arm. As well as drilling rigs, as well as **, cattail bales, coke, and other supplies. The people will not need 35,000, mainly for the cost of materials. The iron pillar is not discussed, and the expenditure of 200,000 yuan cannot be discussed. But fortunately, there is no hurry, even if it is the Danshui Canal, you can go from easy to difficult, starting from the beach to the rocky reef.

A large amount of materials arrived and were lost to Wei Hongji and Zhu Jingze. He took Wei Xuantong and Wei Siqian to Danshui again. Yao Xuan was not there, and Li Wei had to preside over it himself. There is no immediate construction, and further investigation is being done, not only to eliminate the dangerous shoals, but also as an auxiliary canal, and in the future, the volume of water transportation will increase, and the deadweight tonnage of the ships will also increase. In particular, in some rapids, it is also necessary to set up plank roads and pull them on the back of a slender man to allow the ship to sail safely.

I have to dig a safe plank road again.

In addition, the middle and upper reaches of the project are larger, and further investigation needs to be sent.

The smaller the water, the lower the construction difficulty and the more cost-effective.

At the end of September, Li Wei's money trick was finally revealed, but this time the controversy caused was even greater.
