Pan Mei also stretched out her head and said, "It's a good idea. If you can't implement it, it's better to use your cement."

This is a metaphor. No matter how much you use it, it is not as expensive as reinforced concrete. Moreover, seawater is extremely corrosive to cement. If you want to prevent seawater corrosion, the technology is too complicated, and Song Jiu doesn’t know. Could it be that it will be tested for another three or four years?

Therefore, with this product in hand, the fish scale pond, flatten the stones, and the source of the stones is easy. Ask the court to ask some craftsmen to come and then transfer some sulfur to come. There is nitroso soil in the local area, which can blow up mountains and roads. The whole stone is developed using the developed water system of Guangnan and transported to Guangzhou by ship. Even the labor problem will not be too big. Like in Hunan, you can change the land and circle it out, but you have to do this work, including building dikes or moving stones. The court supports some building materials in the middle.

This cost would not be too high, just like Cai Xiang spent only a few thousand chunks of ​​to build the cross-sea bridge.

But there is one of the most important things in the Fish Scale Pond, that is, it is necessary to use stones to connect the stones together with iron chains. Even if the tsunami comes, you can't even think about destroying this embankment. If you build a few miles of long embankment, it's okay. In a Pearl River Delta, how long the coastline is, how many iron chains are to be used. So Yan Tong was happy first and then his eyes were dull after seeing it.

Song Jiu said: "It is inappropriate. Cement cannot withstand the corrosion of seawater. It can be used, but it can only be used above the tide in August. In this way, although hurricanes are washed away for a short time, otherwise the seawall will collapse without waves after a long period of soaking through seawater. However, some river embankments can be used. Fresh water does not have much harm to its corrosion, but there are various limitations. The cement strength is not high now. The maintenance time is too long and large-scale construction cannot be done. It is of two properties to the river. Either new cement, I left the capital. I don’t know how the students are doing researching it."

"There are also letters written by your students here," Pan Mei said.

Song Jiu opened the letter and said some academies and other things, but mainly talked about some confusions in the technical research process, including cement. Seeing that there was progress, Song Jiu frowned and thought that he was not omnipotent. Even scientists came here, so they might not be able to do it. Maybe they had stronger professional knowledge, but they would not be mixed if they were sophisticated. They might not be better than Song Jiu.

A letter was quickly replied.

Tian said, "You have dinner too."

"Wait a minute, the main thing is important," Pan Mei said. Now it's a gathering of four people, and they will be in their own prefectures in the future. The entire Lingnan plan has to be discussed so that there will be direction. Otherwise, just like a marching battle, there is no direction. How can I fight?

Tian retreated.

Song Jiu said: "If nothing is wrong, there will be news at the end of the year."

Then he asked Pan Mei in a low voice: "Do Yan Tong have any respect for water conservancy?"

"He is from Tanzhou. He helped some officials in Hunan to preside over some small water conservancy projects. Later, we adopted half of your water conservancy projects. After hearing this, I transferred him to my account."

Yan Tong was thinking, but when he heard this, he bowed.

After a while, he said, "Song Zhuan. The young man has a way."

"Tell me. This method was not what I thought of, but I heard people talk about the strategy of Qian Chu, Wu Yue, to control the Qiantang River. Use bamboo cages to sink stones."

“Tell me.”

"The Qiantang River tide is larger than the sea tide, and the river damages many times. King Wu Yue came up with an idea, erecting large wood as a trellis, and then using bamboo cages to sank the stones into the bamboo cage. The principle is very similar to that of your iron chain pond, which is to try every means to connect the river embankment and sea walls to increase the ability to resist tides."

"Cage Stone Method."

"It may not be correct. Bamboo will also rot, but it can have decades of tide resistance. Therefore, I have an idea in my mind, use all methods together. Send officials to investigate and use your strategy in the steep sea section, but you can't use iron chains. The cost is too high, so you can use thick hemp rope instead. The secondary sea section uses bamboo cage to sink stones. Use earth dikes directly in the gentle section. Then, build the sea wall wide and make the above roads, so that pedestrians and vehicles pass by, and after pressing for a few years, all of them will be compacted, and the sea wall will be worry-free. Then use your new cement on the water. If you want to build a sea wall, when the tide is low in the second half of the year and the tide is flat at the beginning and end of the month, you can start construction in half a year. Just when the sea wall is compacted next year, your new cement will come in handy."

"I will use a lot of money." Yin Chongke said.

"There is nothing that the small one can do. How can the seawall be achieved without money? For example, Qinjiang, the small ones in Qinjiang have also looked at the map, and the area is very large, almost ten thousand hectares. If you work together, build a stone dam at the upper water source, block water from one stone dam, and build a water dam in the middle of the river to prevent drought and can store some of the water from the mountain torrent during the flood season. The small ones have read the diary of Song Zhuan. There are many reasons for the mountain torrents. One is the torrential rain caused by the arrival of the typhoon, and the other is the damage to the water and soil, especially the people's slash-and-burn farming. Wherever you go, all the forest mountains are burned into barren mountains. Song Zhuan, are the small ones right?"

"Well said, keep talking."

"If the development is successful, the people will give up slash and fire like some areas in Hunan with good water conservancy conditions, but this is not the main thing, it is mainly how to develop it. The middle and upper reaches are controlled together, and the downstream is encircled. This iron chain pond and stone pond with no cost is needed. As long as a soil embankment is built, the stone embankment is added to the key part, and the new cement sent by the Song Dynasty, then thousands of hectares of fertile fields will be used by the people. I heard that Qinzhou is also a severely affected area of ​​miasma. If the theory of the Song Dynasty is adopted, it is mainly the poison gas and mosquito poison produced by these silted and wet lands. In fact, once it becomes a surround field, it is like Tanzhou and

Like Dongting Lake, it is a fertile soil that has not been used for thousands of years and is the first-class fertile land. Without these wetlands, even the miasma has been reduced. Also, because the river water alluvial water has alluvialized a lot of mud and water in Qinjiang Bay, the southern sea area is not deep, which is not conducive to the sailing of large ships. However, most of the time, the calm waves are calm. First, it is beneficial to the salt-drying method transferred by the Song Dynasty. If the price of salt drops, there are many fishermen in Qinzhou who asked them to marinate sea fish with salt and transport it from Lingqu to various parts of the Central Plains. Then they encourage their advanced planting and breeding. Guangzhou becomes the pearl of Guangnan, and Qinzhou can also become the pearl of Guangnan in the western region."

"Well said, keep talking."

"I dare not, Song Zhuan, if the entire Guangnan is cultivated properly, how much farmland can it be obtained?" Yan Tong asked. This obviously exceeded his knowledge.

"If developed properly, the entire Guangnan can obtain more than one million hectares of arable land, and then the advanced farming methods are fully implemented. Just one Guangnan can support all the people in our dynasty, the Tang and Min Khitan Dali and Tubo. But don't think about this. There are no people in Guangnan, and there are no so much money and silk."

"There will be so many?" Xie Yan asked in surprise.

"The entire Guangnan area is almost 450,000 to 500,000 square kilograms. A square kilogram is nearly 17 hectares, and even if 15% of the development is developed, how much arable land will be obtained, you can calculate it yourself. And it can easily ripen two times in a season, abundant water resources, and produce much higher than that in the north. If you leave out the planting of fruits and vegetables, as well as tea, can you plant tea, sugar, mulberry, hemp and cotton, and half of the arable land grow grain. There are at least 600,000 hectares of arable grain farmland, and a hectares of 300 stones, can you support the people in the world?"

“So it’s a good place.”

Song Jiu didn't want to answer, but he said it was not exaggerated. In broad terms, Guangnan now includes part of Yunnan and Guizhou and part of Vietnam, with an area of ​​nearly 48 square kilometers, but it is impossible to use it all. Especially in the western region and Wuling region, even Pan Mei turned a blind eye and did not dare to have much thoughts, and said to Yan Tong: "You continue talking."

"The young man also thought so. But he didn't expect so many... but there were too few people."

"Tell me directly!" Pan Mei shouted. There were fewer people, and he killed tens of thousands of people. It would be better not to mention this.

"Yes. So the small ones think that they cannot fully expand, just grasp a few centers of gravity to manage. For example, Shaozhou. Use it to model mountain valley basins and model more experience. For example, Guangzhou and Chaozhou Evil Creek Delta. The west is Guizhou and Yongzhou. Qinjiang has few people, so it is hard to say whether it can be managed. It is easier to manage from Yonggui eastward. The pseudo-Southern Han also summoned many barbarian soldiers. They were defeated by General Pan one by one, and used both kindness and power. Even the barbarians gradually became sincere and became mature barbarians. However, it was not easy to manage from Yonggui westward. But we could not give up and choose a few mature barbarians friendly to the court to manage them, just like in Hunan, with Chenzhou as the center, driving the surrounding mature barbarians and raw barbarians. There are so many small ideas."

"You write down this idea and write two more. One is spices. Many spices in the South China Sea can also be planted in Guangnan, so that maritime merchants can get their seeds or seedlings and transfer them to Guangnan. Secondly, maritime merchants go to sea implement the joint protection law."

"Joint Guarantee Law?"

"After purchasing the goods, they are registered with the Maritime Bureau. Except for the state prohibited materials, they do not ask about the source of goods or the purchase price, and they can register together before they can get on the ship. All the people and goods on the ship are recorded. After they arrive on the other side, they join forces to sell them. If they encounter robbery or shipwreck, they will compensate each other at the price."

"Hezhou Stock Exchange?" Xie Qi said.

"It's not the same model. In Guangnan, they have a lot of autonomy, mainly forcing them to force unite after going to sea. There are many manpower ships, which can resist pirates and avoid being bullied in foreign lands and take risks together. They can save money from getting rich, or their families die overnight. Another way to make up for one, I have seen the ships now, and it's not appropriate. Let the boatmen study together, divide the cabin into a large number of cabins or a dozen cabins. If one hits a reef and gets water in, the ship will not sink. Even if it sinks, the speed will be slow. If there is time, it's enough for people to escape. Even if several ships work together, they can rescue them in time. The property doesn't matter, people must be safe. Reduce the mortality rate at sea."

Yan Tong started writing.

Wang Ming asked, "Where is the money?"

You have to use money.

"This is the memorial we want to write, let me write it." Song Jiu began to write and asked Zhao Kuangyin to ask all the Lingnan taxes this year to stay. Not many, including other prefectures and counties in the Song Dynasty. Some of the taxes collected must be left to local expenses, and the rest can be paid. Maybe Lingnan will be better next year, but this year will not work. In the past, heavy taxes were exempted one by one, and the amount could be increased was nothing more than the taxes brought by the industries in Song Jiuhezhou. On individuals, the number is huge, but it is nothing in Lingnan. However, if you are careful in calculating, you can still pay nearly one million taxes to the court.

The court and Song Jiu detained the tax of this branch. He asked the court to support craftsmen and sulfur and allowed Guangzhou to temporarily set up a gunpowder division. Guangzhou could ignore it and let the court send officials to supervise it, but it must be set up in Guangzhou, otherwise the amount of gunpowder would be too large and the cost of transporting from the capital was very high. Fearing that Zhao Kuangyin would not be willing to let go, or the officials in the court did not take Guangnan seriously, Song Jiu wrote another thing, preparing to study something in Guangnan. Once it succeeded, it would only bring at least millions of dollars to the country in a year. He wrote the last thing, that was, to recommend Yan Tong as the deputy envoy of transportation.

Wang Ming pondered: "This..."

"If I don't do it, I plan to not do it either. It's too annoying. People can understand it if they do it well. If they don't do it well, people will hate it. However, if they do it, they need talents and use talents in a non-conspicuous manner."

"Deputy Envoy of Transportation." Wang Ming shook his head and looked at Yan Tong again. Yan Tong obviously didn't know and continued to write hard. The opportunity came. He wanted to perform well. He was a magistrate! But he didn't expect that Song Jiu would recommend him as the Deputy Envoy of Transportation, and he didn't even dare to think about it.

Wang Ming also began to write memorials.

He said one thing: Lingnan's terrain is complex and there must be losses during transportation. Therefore, in the past, the loss of one stone in the Southern Han Dynasty was that one stone had to be consumed for eight dou. Later generations may be confused about this quantity. The stone was a unit of weight, less than 100 kilograms, and according to Song jin, it was only eighty kilograms. Dou was a unit of volume. If it was light millet, one stone could reach ten dou, but that was the story before the Tang Dynasty. The grain of the Song Dynasty was mostly wheat, rice or rice. Wheat and rice were better. If it was rice, it would be miserable. It could only be seven dou for one stone. What was produced in Guangnan? It was rice, which means that the loss exceeded the tax. This was the rule of the court, and it could be three times and four times higher than the tax. The loss must be, otherwise the tax would be uneven, but this was too heavy. So Wang Ming issued a government decree in Guangzhou, and the loss of one stone was set as one dou, and the summer tax was collected first. How much was set, please Zhao Kuangyin decided.

When Song Jiu saw Yan Tong writing, he wrote another letter to the students, pointing out the direction.

After Yan Tong finished writing, Song Jiu said, "You go back and pack your luggage and go to Huizhou with me. From now on, you will be a member of Huizhou for the time being."

There is also a Tongzong, but this Tongzong supervises the magistrate. Nanhan does not have this position. Most of the prefectures in Guangnan do not have it now. Pan Mei and Song Jiu have no right to appoint him, so he will first be a magistrate. The right is about the same size as the magistrate.

Yan Tong went back happily.

Wang Ming said: "This kid is lucky."

Then he looked at Song Jiu again.
