However, for Li Shu, since the amount of work to transform the five major grain-producing areas itself is already so terrible, and the amount of water required for this construction is not generally large.

In this case, why not look at the construction of the water conservancy network as a whole, integrate the planning, and build the Grand Canal as the core, anyway, the amount of work is already large enough, and there is no need to worry about whether it will become more.

For more than 100,000 people, there is not much difference between the 25-year project volume and the 30-year project volume, and if it is built together, it can also connect and integrate the water veins involved to form an internal pan-river network, and completely solve the water network problem of several states in the Central Plains.

The blueprint that Li Shu hung for everyone present made everyone stunned, but this amount of work is simply too terrible, so terrible that Chen Xi is a little big, this is not a canal construction plan at all, it is simply a northern agricultural transformation plan.

Li Shu told all his plans, everyone present was a little confused, this blueprint was a little big, and from Li Shu's meticulous planning, everyone could feel the feasibility of this plan, but this plan was too big.

"On the whole, that's it, with the current execution under the rule of Xuande Gong, as well as the investment of people in the leisure time, as well as the overall planning and split construction, in my calculations, the main construction should be completed in 30 years." After Li Shu put down the entire plan, he looked at everyone present and said, his expression was slightly conceited.

Jia Xu, Li You and others immediately began to estimate the effect of the water conservancy network after it was completed, Lu Su began to calculate the level of investment required once the construction began, and Xun Yue frowned and began to think about the changes in its input and output.

Li Shu's plan obviously has traces of several generations. It may be regarded as the wisdom of several generations of the Li family, even if it is the wisdom of Jia Xu and others. It's hard to pick out the glitch in a short period of time.

"This plan, I can't pass it." But it doesn't take that long. Chen Xi directly vetoed this plan.

"Why?" Li Shu, who was originally a little conceited, was obviously dissatisfied at this time, and looked at Chen Xi and asked rhetorically.

"Have you had an overall assessment of how many rivers this canal would have to pass through to build it this way?" Chen Xi didn't care about Li Shu's expression, theoretically speaking, everything seemed to be fine, but in practice, it was impossible to have such a good result.

"More than two hundred." Li Shu answered without a pause, and it could be seen that their family had 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?"

"Not really." Li Shu said bluntly.

"Have you calculated the amount of water needed for the construction of your water conservancy network, and the amount of water withdrawn from the river along the way?" Chen Xi smiled and said, this project is not suitable for this era, it is too big, and if it is completed, it will be more exaggerated than the south-to-north water diversion on the eastern route.

"There's no accurate data." Li Shu said with a slight frown.

"Have you done any research on the climate impact of that massive river diversion?" Chen Xi looked at Li Shu and was still flat.

"In this case, part of it is about the impact of the diversion of the Yellow River and the Yangtze River on the climate of the two places." Li Shu thought about it for a while and said that their family did have some relevant materials. Although this aspect is basically not taken seriously.

"Then, do you think if you build like this, what impact will it have on the five major grain-producing areas and Yangzhou?" Chen Xi sighed and said, in ancient times, they did like to record something that didn't mean anything to them. But it is a very valuable thing to study for future generations.

Li Shu was silent, and after a long time, he looked at Chen Xi and asked, "What does Chen Hou mean?" Building a water network in this way is not only not beneficial, but also disadvantageous? Will it cause local climate change? ”

"Well, I have here a record of the annual precipitation in the five major grain-producing areas. There are also changes in the hydrology of local rivers, and in general, there is no shortage of water in the five major grain-producing areas. It's just a matter of planning. Chen Xi nodded and said.

This is also the reason why Chen Xi's spiritual talent effect is so good, precisely because there is no shortage of water in general, Chen Xi's spiritual talent just rearranges the time of rain and sunshine, which can make the year better.

If this is in a place like Taklamakan where there is only a little bit of rainfall, even if Chen Xi wants to rain, he needs to drag the rain clouds from other places, otherwise, it is basically meaningless to rely on redraining the rain and sunshine time.

This is also the reason why Chen Xi has less energy loss in these places, after all, there is no need to travel through mountains and rivers to carry rain clouds, only basic deployment is required.

"Such a reason is actually a reason to reject our Li family?" Li Shu reprimanded.

"......" Chen Xi rolled his eyes, "I think your Li family had better verify it, and this amount of work is not suitable." ”

"How can you not do such a thing because the project is huge, don't you hear that the nine-story platform starts at the end of the day!" Li Shu looked at Chen Xi indignantly, and even his eyes showed disdain for Chen Xi.

"The problem is, the disadvantages of your project are too great, I do want to build five major grain producing areas, and I do want to build a water conservancy network, but I don't build it this way, the construction of the Grand Canal, for me, is essentially to strengthen the connection between the north and the south." Chen Xi shrugged his shoulders and said.

"As for passing through the five major grain-producing areas, the reason for this is estimated to be known to everyone here, and the canal will eventually merge into the Yellow River to the west and finally enter Chang'an." Chen Xi explained plainly.

The huge inverted character "human" happened to wrap the grain-producing areas of the Central Plains in it on the map, which was of great significance to the rule of the central government.

In addition, after the establishment of the Grand Canal, except for Liangzhou and Yizhou, other states can basically take the waterway to quickly transport troops, and the army line of land and waterway operation at the same time is of great significance for the rule.

Therefore, whether it is to strengthen the central rule or the communication between the north and the south, there is no doubt that the canal needs to be built, but it is obvious that the Li family misunderstood Chen Xi's point of view, and in his opinion, the ultimate meaning of the Grand Canal has become a water conservancy network connecting the five states!

This is not Chen Xi's purpose, the water conservancy network of the five states should indeed be built, but if this water conservancy network is not based on the water veins within the five states, but on the Yangtze River, the Yellow River, the Huai River, and the Haihe River, then the final construction success may really become a disaster.

PS: Tomorrow's monthly pass is left to me.,I'll open a single chapter at night to ask for a ticket.,I'm going to compete for the list.,I heard that there's an event on the fifth.,I'm going to explode more......

There is also a monthly ticket that can't vote for me, you can vote for it, I don't know what the situation is now......
