Of course, Li Shu was very dissatisfied when he left, and Chen Xi was also a little disappointed, saying that he was a good researcher of water conservancy and had a family with extremely high attainments, so he liked to play freely so much.

"Forget it, without the Li family in Yizhou, it won't be even." Chen Xi said speechlessly, and then asked with the idea of waste reuse, "Do you remember the five-state water conservancy plan he just talked about, as well as the detailed five-state water conservancy plan?" ”

"Remember everything word for word, and the map can be restored in its entirety, but why do you use it if you think his construction method is not suitable?" Li You said angrily, show them these things once, and they will be enough to remember.

"To be honest, if it doesn't involve the Grand Canal, I appreciate his water conservancy network construction very much." Chen Xi sighed and said, and then explained to them some of the climate changes caused by the hydrological changes that were made public in later generations.

The large-scale direction of water veins has a huge impact on the local climate change, and Li Shu's plan is based on a large number of water transfers from the Yangtze River, the Yellow River, Huaishui, and Haihe River, and the transfer to the five states of Qingxu, Yan, Henan, and Hebei, which are not short of water in the first place, but are only unreasonably allocated.

Such a large-scale transfer of water veins will definitely lead to a large increase in rainfall in the five states where there is no shortage of water, which will affect the entire climate, and it is not a problem to form floods.

After all, the eastern route of the South-to-North Water Diversion Project caused considerable trouble in the same area in later generations because of this, and this area itself is not short of water, and the temperate monsoon climate can only be said to be unreasonable in the allocation of water resources, not a lack of water resources.

Therefore, Chen Xi's original plan was to carry out water conservancy allocation within the five states, but not to transfer water from other rivers. It was only deployed within the five states, and Li Shu's approach was to directly involve the main water veins in the Central Plains.

Even in the Hereafter. Related majors have been studied for decades, and various disciplines that do not exist in this era rely on mainframe computers to deduce. There is no guarantee that climate change caused by changes in water veins will do more harm than harm to the environment as a whole, or that it will do more harm than good.

And Li Shu is so sure now, Chen Xi can believe it, there is no way to answer the amount of rainfall and water withdrawal, how can Chen Xi believe that even if the Li family does have merit in water conservancy network planning, but Chen Xi will not pass.

That's it, he didn't even have a complete answer to the amount of precipitation, the amount of water withdrawn, and the changes in hydrology to the environment. Not to mention how to suppress environmental changes caused by large-scale hydrological changes. Chen Xi shrugged his shoulders and looked helpless, "You say I dare to agree?" ”

"The reason why the Jiangnan region is hot and humid and rains more than the north is to put it bluntly, it is a climate problem, but these are not simply water veins, but the collision of the climate of the ocean continent, how many people in the world think are studying these now?" Chen Xi misses the geography he studied at the beginning.

Li You, Jia Xu and the others were dumbfounded, these things were already heavenly books for them, but they didn't know why they sounded very emotional. The climate is really worth studying.

"Therefore, if you really do it according to the Li family, the water of the Yangtze River and the Yellow River will be water. The water of the Haihe River and the Huai River is so squandered, and the climate of the entire Central Plains may become the situation of Zijing's family in June and July at that time. Chen Xi said angrily.

"Not really." Lu Su said with some weakness. After all, he couldn't understand these things Chen Xi said at all, but he could still understand the systematization and rationality in them.

"I don't know. Just say it's possible. Chen Xi said with a smile, "So we drew the framework of the Li family's five-state water conservancy transformation." Then you can renovate it, and you don't need to use the water of those four rivers, you can limit the amount of water in those four rivers. ”

"Are you sure it won't make much of a difference?" Jia Xu listened to Chen Xi's catastrophic theory of environment and climate, and he was also a little entangled in the Grand Canal.

"It's not a big problem." Chen Xi said with a smile, "Although it has an impact on both sides of the river, it has little impact on the whole, not to mention that the purpose of repairing this thing is actually more to strengthen the connection between the rulers, and it has obvious benefits for the flow of troops and personnel." ”

"Then fix ......" Jia Xu doesn't have any good way, it seems that the world understands the climate and environment in front of him, and that's not what people say.

"Let's restore the water network map of each state first, and I'll forget about it after a while, I don't have as good a memory as you do." Chen Xi raised his hand and signaled everyone to hurry up and restore the water conservancy network in the five states.

When Li Shu left, he took everything away directly, making it clear that he didn't plan to help Chen Xi, and Chen Xi was also slightly dissatisfied with the Li family's disagreement with his own requirements, so when the two were not compatible, Chen Xi decisively prepared to find someone else to build.

Anyway, the Li family's water conservancy network framework map is in hand, as long as someone changes it, remove the influence of the Grand Canal, and change it to local water extraction, Liu Yan, a water conservancy expert of this level, has also recruited several.

About half an hour later, the five people present restored the framework map of the five states, but it was obvious that there were some gaps in their respective restoration maps, although they could generally say a word that they would never forget, but there were still gaps between people.

A person like Li You with a solid foundation can even mark the villages marked on the map, as well as the estimated underground water veins, and detailed excavation data, while people like Chen Xi can only draw the general veins, mark the counties, and the hills they have passed.

"Take it, I'll mark everything you didn't mark." Li You sighed, he knew that this group of guys could not fully recover, except for the fact that he was basically a superhuman talent, but there was no habit of paying attention to him everywhere in order to exceed his own limit.

Chen Xi was a little embarrassed, he really drew the roughest, there was no way to say that he had the mental energy to strengthen his memory, and he could barely achieve the level of instantly strengthening his memory, but there was always some gap.

"Zichuan, you have learned too much and too much, you should forget some knowledge that is not very commonly used, so that it is good for you to memorize things." Xun Yue nodded at Chen Xi, but he didn't think that Chen Xi's talent was bad, but he just thought that Chen Xi had memorized too many things before, which had an impact on what he remembered now, after all, there was a limit to human beings.

"I do my best." Chen Xi pulled his lips a little embarrassed, it was not that the number of memories was about to go online, but that there was a gap between him and these people in terms of true talent.

"Okay, that's pretty much it, let's find a group of obedient senior water conservancy architects, and we will officially send someone as the leader." Li You quickly filled in the details on each planning map, and then proposed. (To be continued.) )

PS: Happy April Fool's Day to all of you, I'm wondering if I will be beaten to death if I say I'm going to be angry in a few days......
