Pan Mei also stretched out her head and said, "It's a good way, 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, and seawater is also extremely corrosive to cement, if you want to prevent seawater corrosion, the technique is too complicated, and Song Jiu doesn't know how to do it. Is it difficult to become it to try again for three or four years?

Therefore, with this product in hand, the fish scale pond, the stone is flattened, the source of the stone is easy, ask the imperial court to ask some craftsmen to come, and then transfer some sulfur over, there is local nitrate, you can blow up the mountain and build roads, the whole stone uses the Guangnan water system to develop, and it is transported to Guangzhou by ship, even the labor problem will not be too big, and Hunan, the land is changed, and the circle is yours, but this work also has to be done by you, including building embankments, or moving stones. The imperial court supported some building materials in the middle.

This cost will not be too large, just like Cai Xiang later spent only a few thousand yuan to build the cross-sea bridge.

But there is one of the most important things in the fish scale pond, that is, it must be drilled with stones, and then the stones must be connected together with iron chains, so even if the tsunami comes, it is not necessary to destroy the embankment. If you build a few miles of long causeway, it is okay, but in a Pearl River Delta, how long the coastline is, and how many iron chains are used. Therefore, Yan Tong was first happy and then his eyes were gloomy after seeing it.

Song Jiudao: "No, cement can also not withstand the corrosion of seawater, it can be used, but it can only be used above the head of the tide in August, so that although the hurricane washes it, it will be short-term, otherwise the seawall will collapse without waves after a long time of soaking in seawater." However, some river embankments can be used, and fresh water is not harmful to their corrosion, but there are also various limitations, and the strength of cement is not high. The maintenance time is too long, and large-scale construction is not possible. With the river island is two natures. Either new cement, I left the capital. I don't know how well the students are studying. ”

"And here are the letters that your students wrote to you," Pan Mei said.

Song Jiu opened the letter, and the letter said some things about the academy and other things, but the main thing was about some confusion in the process of technical research, including cement. Seeing that there was progress, Song Jiu frowned and thought, he is not omnipotent. Even scientists can't come over, maybe they are more professional, but they won't be mixed if they are fine. may not be better than Song Jiu.

A quick reply to the letter.

Tian said, "You guys have dinner too." ”

"Wait a minute, it's important to get down to business," Pan Mei said. Now it is a gathering of four people, and in the future, they will be in their respective state capitals, and they must discuss the entire plan of Lingnan, so that they can have a direction, otherwise it will be like a march and battle, and there is no direction, how to fight?

Tian stepped back.

Song Jiu said: "If there is no mistake. There will be news of the new cement at the end of the year. ”

Then asked Pan Mei in a low voice: "Is Yan Tong good at water conservancy?" ”

"He is from Tanzhou, and he helped some officials preside over some small water conservancy projects in Hunan, and later we adopted half of your water conservancy projects. When he heard this, the old man transferred him to my account. ”

Yan Tong was thinking about it, and when he heard it, he arched his hand.

After a while, he said, "Song Zhuan." There is a way for the small ones. ”

"Tell me. I didn't come up with this method, but I heard people talk about Wu Yue's strategy to govern the Qiantang River. Sink the stone with a bamboo cage. ”

"Tell me."

"The tide of the Qiantang River is greater than the tide of the sea, and the river has been harmed many times. King Wu Yue came up with an idea, set up a big wood as a fence, and then use a bamboo cage to sink the stone in the bamboo cage, the principle is very same as your iron chain pond, that is, to find a way to connect the river embankment and seawall as a whole, increase the ability to resist the tide. ”

"Cage Stone Method."

"It's not necessarily right, bamboo will also rot, but it can resist moisture for decades. Therefore, there is an idea in the little one's heart, and all the methods are used together. Send officials to investigate, and use your strategy in the steep sea sections, but you can't use iron chains, the cost is too high, and you can use thick hemp rope instead. The secondary sea section uses the bamboo cage sinking stone method. Gentle sections are directly used with earthen embankments. And the seawall will be widened, so that the top into a road, so that pedestrians and vehicles pass through it, every few years, all compacted, the seawall can be worry-free. Then use your new cement on the water. If you want to repair the seawall, 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. By next year's seawall compaction, your new cement will come in handy. ”

"It's going to take a lot of money." Yin Chongke said.

"There's no way to do the little one, how can the seawall be made without money? Another example is the Qinjiang River, the small one of the Qinjiang River has also seen the map, where the area is very large, almost reaching 10,000 hectares. If all parties work together, build stone dams in the upper water sources, block water in stone dams one by one, and build water weirs (reservoirs) in the middle reaches, which can prevent drought and store a part of the mountain flood water in the flood season. The small ones have read the diaries of the Song envoys, and there are many reasons for the flash floods, one is the torrential rain brought by the arrival of the typhoon, and the other is the destruction of water and soil, especially the slash-and-burn cultivation of the people. ”

"Well said, keep talking."

"If the development is successful, the people will give up slash-and-burn farming, just like some areas in Hunan with good water conservancy conditions, but this is not the main thing, the main thing is how to develop. The middle and upper reaches of Qizhi, the downstream to open the siege, this does not need to cost a huge iron chain pond and cage stone pond, as long as a soil embankment is built, in the key part of the stone embankment, and the kind of new cement transferred by the Song Dynasty, then ten thousand hectares of fertile land is civilian. If it is according to the theory of the Song Dynasty, it is mainly the poisonous gas and mosquito poison produced by these wet places, but in fact, once it becomes a field, it is like Tanzhou and Dongting Lake, which is a fertile soil that has not been used for thousands of years, and it is a first-class fertile land, without these wetlands, even the miasma has been reduced. Also, Qinjiang Bay because of the river alluvial down a lot of muddy water, the southern sea area is not deep, not conducive to the navigation of large ships, but most of the time the wind and waves are calm, one is conducive to the Song Dynasty to turn the kind of salt method, if the price of salt falls, there are many fishermen in Qinzhou, let them use salt to pickle the sea fish, can be transported from the Ling Canal to all parts of the Central Plains. Then encourage its advanced planting and breeding, Guangzhou will become the pearl of Guangnan, and Qinzhou can also become the pearl of the western region of Guangnan. ”

"Well said, keep talking."

"Don't dare, Song Zhuan, if the entire Guangnan is properly cultivated, how much arable land can be obtained?" Yan Tong asked. This was clearly beyond his knowledge.

"If properly developed, there will be more than one million hectares of arable land available in Quang Nam, and then advanced farming methods will be fully implemented. Just one Guangnan can feed all the people of our dynasty, Tang, Fujian, Khitan, Dali, and Tubo. But don't think about that. Quang Nam has not so many people, and there is not so much money. ”

"Will there be so many?" Xie Wei asked in surprise.

"The entire area of Quang Nam is almost 450,000 to 500,000 square meters. One square meter of Huangli is nearly 17 hectares, and even if 15 percent is developed, how much arable land will be obtained will be calculated by yourself. And it can easily be harvested twice in one season, rich in water resources, and the yield is much higher than in the north, leaving away the cultivation of melons, fruits and vegetables, as well as tea, cane, mulberry, hemp and cotton, and half of the arable land is planted with grain. There are at least 600,000 hectares of arable grain farmland, and one hectare of 300 stones, can it feed the people of the world? ”

"So it's a good place."

Song Jiu didn't want to answer directly, but he didn't exaggerate, now Guangnan also includes a part of Yunnan and Guizhou and a part of Vietnam, and the area is close to forty-eight square kilometers, but it is impossible to use it all. Especially in the western region and the Wuling region, even Pan Mei turned a blind eye, didn't dare to think much, and said to Yan Tong: "You continue. ”

"The little ones think so too. But I didn't think of so much...... But there are too few people. ”

"Just say it!" Pan Mei shouted. There are few people in the first place, and he killed tens of thousands of people, which is best not to mention.

"Yes. Therefore, the small ones think that they cannot be rolled out in an all-round way, as long as they grasp a few key points of governance. For example, Shaozhou. Use it to model mountain valley basins and model more experience. For example, Guangzhou and Chaozhou Evil Creek Delta. To the west are Guizhou and Yongzhou. There are few people in Qinjiang, whether it can be governed, it is difficult to say whether it is small. It is easier to govern from Yonggui to the east, and the pseudo-Southern Han also gathered many barbarians, who were defeated by General Pan one by one, and used both grace and power, and even the barbarians gradually became convinced and became familiar barbarians, but it was not easy to govern from Yonggui to the west. But we can't give up, choose a few familiar barbarian areas that are friendly to the imperial court, just like Hunan, with Chenzhou as the center, and drive the surrounding mature barbarians and barbarians. So much for small ideas. ”

"Write down this idea and write two more words, one is spices, many spices in the South China Sea can also be grown in Quang Nam, so that the maritime merchants can get their seeds or seedlings and move them to Quang Nam. Secondly, the joint guarantee law shall be implemented for maritime merchants going to sea. ”

"Joint Guarantee Law?"

"After they buy the goods, they are registered in the city shipping department, except for the materials prohibited by the state, regardless of the source of the goods, regardless of the purchase price, they join forces to register, and then they can get on the ship. All the people and goods on board are recorded. After arriving on the other side, they will sell together, and in case of robbery or shipwreck, they will compensate each other with the selling price. ”

"Riverside Deed Shares?" Xie Wei said.

"It's not that kind of model, they have a lot of autonomy in Quang Nam, mainly to force them to unite forcibly after going to sea, there are many manpower ships, and there is a guarantee for resisting pirates, not being bullied in a foreign land, and taking risks together. Save to get rich, or ruin overnight. One more thing, I've seen the current ship, most of them are one cabin, that's not appropriate, let the shipwrights study together, divide the cabin into several cabins or more than a dozen cabins, one of them hits the reef and enters the water, the ship will not sink, even if it sinks, the speed is relatively slow, and there is enough time for people to escape. Even several boats joined hands to rescue in time. Property doesn't matter, people are safe. Reduce mortality at sea. ”

Yan Tong began to write.

Wang Ming asked, "What about the money?" ”

You have to use money.

"This is the memora we want to write, I'll write it." Song Jiu began to write, asking Zhao Kuangyin to leave all the Lingnan taxes this year. Not many, including other states and counties in the Song Dynasty, part of the tax collected must be left for local expenditure, and the rest can be handed over. Maybe Lingnan will be better next year, but not this year, the previous heavy taxes have been exempted one by one, and what can be increased is nothing more than the taxes brought by those industries in Songjiuhezhou. On individuals, the amount is huge, but on Lingnan it is nothing. However, if you plan carefully, you will be able to pay nearly one million taxes to the imperial court. It was this branch tax that Song Jiu withheld. Ask the imperial court to support the craftsmen and sulfur, and allow Guangzhou to temporarily set up a gunpowder division, Guangzhou can be left alone, let the imperial court send officials to supervise, but it must be located in Guangzhou, otherwise the amount of gunpowder is too large, and the cost of transporting it from the capital is very high. Afraid that Zhao Kuangyin would be reluctant, or that the officials of the DPRK and China would not regard Guangnan as one thing, Song Jiu wrote another thing, he was going to study a thing in Guangnan, and once it succeeded, it would only bring at least millions of income to the country in Guangnan a year. wrote the last thing, that is, to recommend Yan Tong as the deputy envoy for transit.

Wang Ming groaned: "This ......"

"Or if you don't do it, I don't plan to do it, it's too annoying, and if you do it well, the people can understand it, and if you don't do it well, the people will hate it. However, if you do it, you need talents, and you can use talents without sticking to one pattern. ”

"The deputy envoy of transport." Wang Ming shook his head and looked at Yan Tong again, Yan Tong obviously didn't know what to do, and continued to write hard. The opportunity is here, you have to perform well, that is a county! But he didn't expect Song Jiu to recommend him as the deputy envoy for transport, and he didn't even dare to think about it.

Wang Ming also began to write recitals.

He said one thing, the terrain of Lingnan is complex, and there must be loss in the transportation process, so the loss of the Southern Han Dynasty in the past is a stone must be exchanged for the loss of eight buckets, and later generations may be confused about this quantity, the stone is a unit of weight, less than 100 catties, and only 80 catties according to the Song Dynasty. Bucket is a unit of volume, if it is light millet one stone can reach ten buckets, but that is the story before the Tang Dynasty, the Song Dynasty grain became more wheat and rice or rice, wheat and rice are a little better, if it is rice can be miserable, one stone is barely seven buckets, what Guangnan produces, it is rice, that is, the loss exceeds the tax, this is the imperial court regulations, to the following can be tripled or quadruple. There must be losses, otherwise the taxes will not be even, but this is too heavy. So Wang Ming issued a decree in Guangzhou, and the loss of one stone was set as a bucket, and the summer tax was levied first. How much is set, please Zhao Kuangyin decide.

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

After Yan Tong finished writing, Song Jiu said: "You go back and pack your bags and go to Huizhou with me, from now on, you will be the secretary of Huizhou for the time being." ”

There is also a general judgment, but this general judgment is to supervise the governor, the Southern Han Dynasty does not have this position, and now most of the states in Guangnan do not, Pan Mei and Song Jiu have no right to appoint, so let him be a secretary first. It is about the same size as the right to know the county.

Yan Tongle went back in a hurry.

Wang Ming said: "This kid is blessed." ”

Then he looked at Song Jiu again.

The general direction is basically set, and the two transshipment envoys, each in each place, what should they do in the future, I feel very sad when I think of this. (To be continued......)
