However, for Li Shu, since the project volume of transforming the five major grain-producing lands itself is already so terrible, and the amount of water required for this construction is not of an average degree.

In this case, why not consider the construction of the water conservancy network as a whole, integrate the planning and build it with the Grand Canal as the core. Anyway, the project volume is already large enough, so there is no need to worry about whether it will become more.

For mortals, there is actually not much difference between the project volume of more than one million people in twenty-five years and the project volume of thirty years. If they are integrated together, the water veins involved can be connected and integrated to form an internal river network, which will completely solve the water network problem of several states in the Central Plains.

The blueprint that Li Shu hung for everyone present shocked everyone, but the project volume was simply terrible, so scary that Chen Xi was a little overwhelmed. This was not a canal construction plan, but it was a northern agricultural transformation plan.

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

"Overall, that's it. With the current execution power under the rule of Xuande, the people's investment in slack farming time, and the overall planning and split construction, according to my calculations, the main construction should be completed in 30 years." After putting down the entire planning book, Li Shu looked at everyone present and said with a slight conceited expression.

Jia Xu, Li You and others immediately began to estimate the effect after the water conservancy network was built, Lu Su began to calculate the approximate level of investment required once 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 generations, and may be regarded as the wisdom of the Li family for generations. Even with the wisdom of Jia Xu and others, it is impossible to pick out burrs in a short period of time.

"I can't pass this plan." However, without waiting for that long, Chen Xi directly rejected the plan.

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

"Have you evaluated the overall number of rivers this canal needs to pass through according to your construction?" Chen Xi did not care about Li Shu's expression. In theory, everything seemed to be fine, but in reality, it was impossible to have such a good result.

"More than two hundred pieces." Li Shu answered without pausing, and it was obvious that their family had indeed done a lot of research in this regard.

"Well, let's put it this way, do you have data on the annual rainfall of the five major grain-producing areas?" Chen Xi asked another question, "Do you have data on the actual rainwater demand in the fields?"

"Nothing is this." Li Shu said bluntly.

"Then are the amount of water required for the construction of your water conservancy network? Are the amount of water intake of rivers along the way calculated?" Chen Xi smiled and said, "This project is not suitable for this era. It is too big. If it is completed, it will be even more exaggerated than the South-to-North Water Diversion on the East Line.

"There is no accurate data." Li Shu said with a frown slightly.

"Have you done research on the impact of large-scale river diverting on the climate?" Chen Xi looked at Li Shu and was still dull.

"In this case, there is part of the impact of the diverting of the Yellow River and the Yangtze River on the climate between the two places." Li Shuluo said after sillying. They did have some related materials, although they basically did not pay attention to this aspect.

"Then, what impact do you think if you build this way will have on the five major grain-producing lands and Yangzhou." Chen Xi sighed and said. In ancient times, he did like to record some things that were of little significance to them, but were of great research value to future generations.

Li Shu was silent, and after a long time, he looked at Chen Xi and asked, "What Chen Hou meant is that building a water conservancy network in this way would not only be beneficial but also harm? Will it lead to local climate change?"

"Well, I have records of annual precipitation of the five major grain-producing areas, as well as changes in local river hydrology. Overall, the five major grain-producing areas are essentially water-deficient, 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 good. It is precisely because overall, there is no shortage of water. Chen Xi’s spiritual talent can only reorder the time of rain and sunshine, which can make the year scene better.

If this is a place like Taklamakan where the rainfall is only a little bit, even if it rains, Chen Xi needs to drag the rain clouds from other places. Otherwise, it will be basically meaningless to rely solely on re-evaluating the rain and sunshine time.

This is also the reason why Chen Xi lost less energy in these places. After all, there is no need to travel through mountains and rivers to transport rain and clouds, just basic allocation is required.

"The reason for this is actually to reject our Li family?" Li Shu scolded.

"..." Chen Xi rolled his eyes, "I think your Li family would be better off verifying it, and the project volume is not suitable."

"How can you not do such a thing that will last forever because of the huge project? You're not hearing that the nine-story platform starts from the end!" Li Shu looked at Chen Xi indignantly, and even his eyes showed contempt for Chen Xi.

"The problem is that your project has too many disadvantages. I do want to build five major grain-producing lands and water conservancy networks, but this is not the case. For me, the construction of the Grand Canal is essentially to strengthen the connection between the north and the south." Chen Xi shrugged and said.

"As for the five major grain-producing lands, everyone here probably knows that the canal will eventually merge into the Yellow River and finally enter Chang'an," Chen Xi explained calmly.

The huge inverted character "man" just wrapped the grain-producing land in the Central Plains on the map, which has great significance for the central government's rule.
