"Aren't you confused?" Chen Chu pouted: "When Yan Huang was alive, the weather was much worse than now, and he couldn't move thousands of miles of red land, could it be that Emperor Yan and Yellow Emperor didn't do as well as the emperors in history?" ”

"The Great Qin Empire unified the world, built the Great Wall, repaired the Chi Road, and the car was written on the same track, how much merit is it, isn't it also the anger of heaven and the resentment, and the second will die?"

"During the Wenjing period, there were still few disasters in the world, there were Xiongnu constantly invaded the south, and the rebellion of the Seven Kings was a disaster in the world, and there were large and small disasters everywhere in all states and counties, did anyone dare to question Emperor Wen Jingdi? There are so many emperors, how many people are qualified to be compared with them? ”

Li Eryi clapped his hands: "Yes, even such an emperor is not peaceful in the world, why is this?" Could it be that God has no feelings at all, is moody, and has no regularity? ”

"You're half right, God is indeed emotionless and moody, but it's not that it's irregular, and God is not a life or existence, it has no consciousness, it's just mythologized by the people as some kind of existence."

"It's going to rain, and you can't stop it because of what people do, unless you can dispel the clouds." Chen Chu said, Li Er shook his head, joking, how could someone do this kind of thing, it was too dreamy.

"It doesn't matter if you are a faint monarch or a bright monarch, when the dark clouds come, he will thunder and rain, and when the dark clouds are gone, it will be a drought and famine, and the yellow water will burst the embankment, it will not change because you are an emperor, what happens in the world, unless you can block the embankment, otherwise you can make a tribute sacrifice, can God listen to you and take back the flood?"

Li Er and Eldest Sun Wuji's faces became a little ugly.

You must know that the sacrifice is a tradition that has been continued through the dynasties, the family sacrifices to the ancestors, and the country sacrifices to the community, asking for the health of the family, the wind and rain, and the peace of the country.

Which emperor didn't sacrifice, and the disaster that should have happened still happened? Isn't he Li Er one of them?

But what Chen Chu said was not polite, and he said that the sacrifice was useless, which still made them unacceptable.

"Don't talk about the current situation of Datang, even if the Turks and Tubo are wiped out now, the entire Datang is now rich and prosperous, the people don't have to worry about food and clothing, and there is no chaos, should he be in drought in Guanzhong, or drought, what does it have to do with the reason for your mess?"

Li Er and eldest grandson Wuji are both people who are familiar with poetry and books, and they recall the history of China for thousands of years, isn't it?

Heaven is moody, not transferred by the will of man, no matter what happens in the world, thunder when it should thunder, rain when it should rain, the emperor feels that his behavior has angered the heavens, and he is somewhat narcissistic......

Li Er's brows gradually relaxed, and a smile appeared on the corner of his mouth, in fact, they had discussed this topic with Chen Chu before, but it was not as thorough as this time.

This time, he really faintly felt that the world might not really affect God, so his Li Er's actions naturally had no impact.

The more he looked at Chen Chu, the more pleasing he became, and the truth that the scholars of the Manchu Dynasty couldn't tell made it easy for this kid to understand.

A group of people who read poetry and books are full of words, but they are not as good as this guy who doesn't even understand the four books and the five classics, what a group of rice buckets.

The eldest grandson Wuji was also in a good mood, feeling that he had understood a big truth.

And the most important thing is that Your Majesty will not stop acting in the future because of scruples about the so-called heaven, which is a good thing.

He reminded: "Then how to deal with the disaster in Guanzhong, Chen Chu, you don't have a clue?" ”

Chen Chu touched his chin: "Anyway, don't think about the crops, there is no help, but the potatoes don't need so much water, as long as the time is planted in a large area, the water required will be directly transported by manpower, and the famine problem in Guanzhong in the autumn can be solved." ”

"That's what so-and-so thinks, too." Li Eryi slapped the table and hurriedly asked, "Are you sure that the potatoes will grow within three months?" ”

Chen Chu was not sure in his heart, but he suddenly remembered that he had nothing to do at home before, the bean sprout seeds in the transparent cup, he watched it grow vigorously day by day, and finally opened the soil, how tenacious the vitality of the plant was.

"There will definitely be no problem, even if the potatoes will not grow more than 30 stones, but the harvest is far from being comparable to other crops, mainly because I am not good at farming." Chen Chu explained.

Li Er looked at Chen Chu's hand, and thought about it, this is white and tender, and the son of the family is basically at this level, and he doesn't believe it when he says that he is good at farm work.

He doesn't need thirty stones, he can have ten stones, thousands of catties, in fact, he is already very satisfied.

"As for the use of water for people and animals, I think so." Chen Hao coughed.

"Gather talents from all over the world, especially those who are good at geography and travel all over the world, let them find water sources and dig wells all over Guanzhong, and then they can order craftsmen to build dikes and store water under the ice and snow meltwater, and then transport them to the surrounding states and counties by manpower."

"Secondly, some areas that are really remote and arid can be collectively relocated, and the population can be concentrated to facilitate management and save transportation costs."

Listening to the three points analyzed by Chen Chu, the two of them were a little dazed, and after coming back to their senses, they hurriedly remembered these three points, and gasped in their hearts.

In fact, in the court, many ministers' discussions are also somewhat related to these three points, but because everyone does not know enough, what they say is vague, and the conclusion is that they don't know what to do.

But these three points mentioned by Chen Chu made Li Er and the eldest grandson Wuji subconsciously feel feasible.

From ancient times to the present, there are many classics such as various geographical chronicles, and there are many people who know about hydrology, presumably they must know more about where to draw water than the local government.

The second is to intercept the ice and snow meltwater, Wuji also said this before, but he mentioned water diversion for irrigation, and Chen Chu is to store water for transportation.

Li Er is inclined to the latter, after all, the amount of water is diverted and dug a canal, and the scalp is numb when you think about it, so it is better to intercept it into a reservoir on the spot, and it would be good if you need to use water yourself.

Population migration is even more unexpected, the people of the Tang Dynasty attach great importance to their hometown, and in previous years, during the war, many people even chose to stay in their hometowns, and only if they couldn't survive such as the plague would they go into exile.

But Datang does not want them to leave their hometowns, but only to temporarily relocate them to places with better transportation, which is convenient for water supply and imperial relief, and then move back when the climate in Guanzhong returns to normal, presumably so that no one will oppose it, and the policy will be easy to implement.

Li Er walked around the room excitedly with his hands behind his back, and the more he thought about it, the more he felt that it made sense.

If these policies are carried out, the disaster situation in Guanzhong will certainly be contained.

When potatoes begin to be planted, there will be grain for autumn and winter, and as for spring and summer, the common people will have food in stock, after all, even if there is no drought, spring and summer are not the harvest season.

After the eldest grandson Wuji was excited, he also calmed down a little: "Chen Chu, if we intercept the water from the source of the Yellow River, will it cause the flow of the Yellow River to decline, affect the irrigation of the middle and lower reaches, and even cause silt blockage?" ”

This is indeed a big problem, Li Er pricked up his ears, wanting to hear what Chen Chu had to say.

Chen Chu was amused when he heard it: "Do you know how many rivers and streams converge at the source of the Yellow River?" Tens of thousands! It's not that I look down on Datang, if Datang can really block water sources everywhere, causing a shortage of water sources in the middle and lower reaches of the Yellow River, it will be really awesome. ”

You must know that the current soil erosion is not as serious as that of later generations, God knows how many main streams converge to form the surging Yellow River, a group of ancients who do not even have the ability to build infrastructure, want to block the Yellow River, dreaming?

Li Er also ran all over the world when he was fighting, and he had a lot of experience, he knew the difficulty of the people starting work in the mountains, even if a large number of people were dispatched, he felt that it would be good to build a few reliable reservoirs, and it would be unfounded if he was unscrupulous.
