"Master Thirteen took the picture and left without saying a word. I thought the picture was stolen." Brother Rong looked at the crowd surrounding the table next to him, and Master Thirteen was actually there.
Master Thirteen did not even look at this guy and continued to chat about the map with the old man who was by the Qinghe River that day.
Jia Rong only looked at the map and nodded repeatedly, praising the map he drew.
"The only thing I don't understand is why the two sides of the river are so constructed." The old man turned his head and asked Brother Rong.
"To prevent soil erosion." Brother Rong said matter-of-factly.
Although the words "soil erosion" are easy to understand, I don't know what they specifically refer to. The old gentleman looked at him doubtfully, but the Thirteenth Master hummed: "Speak like a human being."
"Oh, to put it simply, it is the loss of water and land caused by external forces such as hydraulics, gravity, and wind." Brother Rong walked over, pointed to several meandering places of the Qinghe River on the map, and said: "The Qinghe River is narrow. , not only is it easy to wash away the land on the other side of the river at the winding and bending point, but it also brings the washed-down soil into the river, causing the river to silt up."
Thirteenth Master nodded in understanding, but the old gentleman understood. He said: "To repair the river bank in this way, the money required will increase a lot."
Jia Rong said: "Slope protection and bank repair must be done. Otherwise, if we only build dams and canals at the back, all future maintenance costs will be higher. As long as both sides of the bank are managed well, there will be no need to vigorously clean up the silt downstream. The boy originally said I thought about planting a row of trees on both sides of the river, but then I gave up the idea because of the money.”
The old man smiled and said: "If we only protect the slope in this section of Huangzhuang, the soil on both sides of the upstream and downstream banks will collapse, which will still have an impact on the river."
Jia Rong shook his head and said: "There is no way. The total length of Qinghe River is nearly sixty miles, and the drainage area is three thousand hectares. This project is too big. I can only protect one section at a time. If you want to protect all sixty miles, There are no projects that can’t be completed within a few years.”
The Thirteenth Master looked sullen.
Based on his understanding of Jia Rong, this bastard must have a full set of methods if he can keep Qinghe's situation in the dark and dare to tell her face to face. It's just that this bastard doesn't want to talk about it!
The old gentleman said: "What Sir Rong thinks coincides with what I think. Both sides of the river must be managed, but the way that Sir Rong has abandoned is to plant a row of trees on both sides of the river. Not only that, the river must be intercepted upstream to clear the river silt, and at the same time, sluices must be built downstream.”
"Now that we have cleaned up the river, we can protect the slopes on both sides of the river at the same time, so we can kill two birds with one stone." Uncle Rong said with a grin.
Sixty miles, the two sides are one hundred and twenty miles. How much cement will it take to complete this?
Let Ning Guofu get rich!
It seems that the Xue family must be urged to find a place quickly. The Ningguo Mansion in Zhuangzi outside Shenjing City is a bit small after all, so it may be a bit difficult to supply.
Who said you have to know a lot of things if you want to get rich? Even the simplest piece of cement can make Ningguo Mansion rich.
The Thirteenth Master saw what Jia Rong was thinking and said, "Don't think about cheap things. The Water Conservancy Yingtian Mansion has very little money and cannot purchase cement to build the river."
Although Jia Rong also knew that Emperor Xiande was the most critical emperor in the hundred years since the founding of the Yan Dynasty, he was not only critical of himself, but also of the project. But Brother Rong still wanted to fight for it and said: "Building the river once can guarantee it for a hundred years. Master Thirteenth should not calculate the temporary gains and losses. Once the Qinghe River is managed, the 3,000 hectares of land on both sides of the Qinghe River can be cultivated at least 20,000 acres." Good farmland.”
What is the concept of 20,000 acres of fertile land? If one acre of two dans can be transformed into one acre of four dans, then 20,000 acres of paddy fields will be 40,000 dans more than in previous years. Calculated in kilograms, there are nearly five million kilograms more grain every year.
Brother Rong said again: "If this newly opened 20,000 acres of fertile land can produce 80,000 shi of grain, the rent will be 40,000 shi at half price. If calculated based on the current price of rice, which is more than ten copper coins per dou, one hundred dou One stone, that is, one thousand taels of silver per stone. Calculated in this way, the two sides of the Qinghe River alone can collect 30,000 taels of silver per year."
This is only the increase in the output of fields in the basins on both sides of the Qinghe River.
The Thirteenth Master knew these data better than Jia Rong, and said calmly: "There are 24,000 acres of official land and 8,000 acres of civilian land on both sides of the Qinghe River. The total number of paddy fields that can be converted is 23,000 acres."
More than 20,000 acres of official land? Mintian is only 8,000?
Brother Rong was shocked when he heard this, but there was nothing he could do. The royal family alone once owned more than 10,000 hectares, or more than one million acres, in the Gyeonggi area, all of which were the private fields of Emperor Yan.
There are also countless royal families, princes and princes, as well as the princes and princes below. There are many Zhuangzi in each mansion.
Most of the fields in the Gyeonggi region are monopolized by the upper class!
Calculating the numbers one by one is really shocking. In fact, in feudal society, most of the land in each province was controlled by royal ministers, squires and others. On the contrary, the lower-class farmers, who are more numerous, do not own as much land as these small groups of people.
This is an unsettled account!
Brother Rong said: "That's it. With more than 20,000 acres, the money that can be invested will only be more. Use two or three years of income to build the river, and you will have no worries for decades. It is a business that will make a profit without losing money." .”
"You know how to buy and sell, so I should let you be a cheap businessman." Master Thirteen snorted and left with a handful of blueprints.
The old man was left to consult Brother Rong in Yingtian Mansion about opening rivers and building canals.
"The old gentleman is trying to beat me up, how can I ask for advice, communicate with each other, and communicate together." Brother Rong smiled coquettishly.
…………
"Is Brother Qiang okay at the kiln?" Brother Rong looked at Jia Qiang's increasingly resolute face and felt a little relieved.
He always changed, and this boy finally looked like a man.
Otherwise, continuing like this is not an option. You can't find a man to match Jia Qiang in the future! After all, he was the eldest daughter of the Ningguo Mansion, so how could Jia Qiang's support be eliminated?
Brother Qiang stared at Brother Rong's handsome face for a long time before looking away and said with a chuckle: "It's good together. Brother Qin Zhong has mastered all the methods in just a few months and even brought out several disciples. "
"As long as you can trust it, you can do whatever you want."
Jia Qiang said: "Well, although it is easy to bake cement, the grinding is too slow and the clinker is easy to accumulate. There is a lot of it in the warehouse, and now the kiln has slowly stopped production. According to Master Qin's arrangement, Fuli Village will The kiln above is mainly used for research and testing. Trying to improve the efficiency of grinding."
Grinding cement raw clinker is a big problem. It's not like the various machines in later generations, which all rely on water and manpower. How can this efficiency be improved?
It is worth encouraging them to have this idea.
Brother Rong said: "It doesn't matter if the production is slower. If the manpower is insufficient, add more people. Of course, don't stop researching and testing. You can try to tinker with anything that may improve efficiency."
In fact, Jia Rong had a grinding method in mind, but it was very troublesome. It seems that I have to find an opportunity to talk to Master Thirteen. Maybe the basic physics knowledge of electromagnetism can really come in handy.
Suddenly, Jia Rong slapped his head, wondering why he was so stupid. In fact, there is no need to use electromagnetic principles. You can directly use the existing water-powered mill. As long as the water power is large enough and the power it can drive is sufficient, it is also possible to build a larger mill.
As long as there is enough water, the dam is high enough, and the water pressure is strong enough, won't it be powerful?
Now that we have cement, are we afraid that we won’t be able to build a higher dam? In the past, I only thought about the existing conditions of the world, but completely ignored the cement I brought.
Miscalculation! Miscalculation!
Jia Rong said: "Tomorrow, call Master Qin, Brother Zhong, Brother Yun, Zong Cheng and others. I have a way to improve the efficiency of grinding."
Brother Qiang said happily: "I knew Brother Rong had a solution and should have come to find you earlier."
Jia Rong looked at the strange light in this guy's eyes and got goosebumps inexplicably. He quickly asked Lai Sheng to bring a few boxes of pastries and fruits, and sent Jia Qiang away in a hurry.
I can't stand the strange looks from the same sex.
Brother Rong rubbed his hands and hurried back to the yard to find his wife. Only his wife's warmth could eliminate the power of Brother Qiang's glance just now.
"Master, let's go to Yixia Pavilion today!"
"What?"
