However, for Li Shu, the amount of work required to transform the five major grain-producing areas is already so daunting, and the amount of water required for such construction is not generally large.
In this case, why not treat water conservancy network construction as a whole, integrate planning, and build with the Grand Canal as the core? Anyway, the amount of the project is already large enough, and there is no need to worry about whether it will become more.
For ordinary people, there is not much difference between the amount of work done in twenty-five years and the amount of work done in thirty years for more than one million people. If they are integrated and constructed together, the water veins involved can be connected and integrated to form a
The internal pan-river network completely solves the water network problems in several states in the Central Plains.
The blueprint that Li Shu hung up for everyone present made everyone stunned. However, the amount of the project was so terrible that it made Chen Xi feel dizzy. This was not a canal construction plan at all, but a northern agricultural transformation plan.
Li Shu explained all his plans. Everyone present was a little confused. The blueprint was too big, and everyone could feel the feasibility of this plan from Li Shu's detailed plan. But this plan
Too big.
"On the whole, that's it. Based on the current execution ability under Xuande Gong's rule, as well as the people's investment in leisure time, and the overall planning and split construction, according to my calculations, the main construction should be completed in thirty years.
"After Li Shu put down the entire plan, he looked at everyone present and said, looking slightly conceited.
Jia Xu, Li You and others immediately began to estimate the effects of the water conservancy network after it was completed. Lu Su began to calculate the approximate investment required once construction started. Xun Yue frowned and began to think about its input and output.
change.
Li Shu's plan obviously has traces of being passed down through generations. It may be considered the wisdom of several generations of the Li family. Even with the wisdom of Jia Xu and others, it would be difficult to find faults in a short period of time.
"I can't pass this plan." However, there was no need to wait that long, Chen Xi directly rejected the plan.
"Why?" Li Shu, who was originally a little conceited, was obviously dissatisfied at this time and looked at Chen Xi and asked.
"Have you made an overall assessment of how many rivers this canal needs to pass through according to your construction?" Chen Xi didn't care about Li Shu's expression. In theory, everything seemed fine, but in reality, it was impossible to be like this.
Good results.
"More than two hundred." Li Shu answered with almost no pause. It can be seen that their family has indeed done a lot of research in this area.
"Well, let's put it this way, do you have data on the annual rainfall in the five major grain-producing areas?" Chen Xi asked another question, "Do you have data on the actual rainwater demand per acre?"
"That's not true." Li Shu said bluntly.
"Then have you calculated the amount of water required for the construction of the water conservancy network, and have you calculated the amount of water taken from the rivers along the way?" Chen Xi smiled and said, this project is not suitable for this era, it is too big. If completed, it will be better than the South-to-North Water Diversion Project on the east line.
Also exaggerated.
"There is no accurate data." Li Shu frowned slightly and said.
"Have you done any research on the impact of large-scale river diversion on climate?" Chen Xi looked at Li Shu calmly.
"As for this, it does involve part of the impact of the diversion of the Yellow River and Yangtze River on the climate of the two places." Li Shuluo thought about it and said, their family does have some relevant materials, although they basically don't pay attention to this aspect.
"Then, what impact do you think it will have on the five major grain-producing areas and Yangzhou if you build it like this?" Chen Xi sighed and said. In ancient times, they sometimes liked to record things that were of little significance to them, but of great research value to future generations.
matter.
Li Shu was silent. After a long time, he looked at Chen Xi and asked, "Chen Hou means that building a water conservancy network in this way not only has no benefits but also has disadvantages? Will it cause local climate change?"
"Well, I have the annual precipitation records of the five major grain-producing areas here, as well as the hydrological changes of the local rivers. Generally speaking, the five major grain-producing areas are not short of water. It is just a matter of planning." Chen Xi nodded and said.
This is also the reason why Chen Xi's spiritual talent is so effective. Precisely because there is no shortage of water in general, Chen Xi's spiritual talent only rearranges the timing of rain and sunshine, which can make the year better.
If this is a place like Taklimakan where there is only a little rainfall, even if it rains, Chen Xi will have to drag the rain clouds from other places. Otherwise, it is basically meaningless to just rearrange the rain and sunshine time.
This is also the reason why Chen Xi consumes less energy in these places. After all, he does not need to travel across mountains and rivers to carry rain clouds, he only needs to make basic arrangements.
"Such a reason is actually the reason for rejecting our Li family?" Li Shu scolded.
"..." Chen Xi rolled his eyes, "I think it's better for the Li family to verify it, and the amount of work is not suitable."
"How can you not do such a long-lasting thing just because the project is huge? Don't you think that the nine-story tower was built from the ground up!" Li Shu looked at Chen Xi angrily, even showing contempt for Chen Xi in his eyes.
.
"The problem is, your project has too many drawbacks. I do want to build five major grain-producing areas, and I do want to build a water conservancy network, but it is not built in this way. The construction of the Grand Canal, for me, is essentially to strengthen
Contact between the north and the south." Chen Xi shrugged and said.
"As for passing through the five major grain-producing areas, the reason is probably known to everyone here. Going west, the canal will eventually merge into the Yellow River and finally enter Chang'an." Chen Xi explained calmly.
That huge sideways character "人" happens to wrap up the grain-producing areas of the Central Plains on the map, which is of great significance to the central government's rule.
In addition, after the establishment of the Grand Canal, except for Liangzhou and Yizhou, other states can basically transport troops quickly by waterway. The simultaneous operation of land and waterway troops is of great significance to the rule. Currently, these places belong to the basic territory of the dynasty.
, then it is of great significance to form one!
Therefore, whether it is to strengthen central rule or to communicate between the north and the south, the canal needs to be built. This is undoubtedly
Connect the five-state water conservancy network!
This is not Chen Xi’s purpose. The five-state water conservancy network should indeed be built. But if this water conservancy network is not based on the internal water veins of the five states, but based on the Yangtze River, Yellow River, Huaihe River, and Haihe River, then the final construction will be successful. Really
