"Dai Aiqing, immediately prepare money and food to help the people in the flood discharge area,!" Li Shimin looked at Dai Guandao, the secretary of the Ministry of Civil Affairs on the side, and said solemnly at the same time: "Be more prepared, in case the worst happens." ◢ with ◢ dream ◢ small ◢.lā"

The ministers were shocked, of course they knew what the worst thing was.

"Your Majesty rest assured." Dai Xuan nodded.

In just a few days, Dai Xuan can be said to have collected taxes to a soft hand, and he levied heavy taxes on some luxury goods and silk shipped to the Western Regions according to Merton's tax concept, but he did not expect to receive the slightest resistance, even if the price nearly doubled, these Hu merchants all did not hesitate to pay in full.

For the time being, there was a way to tide over the difficulties, and the atmosphere in the entire court suddenly lightened, and even Li Shimin breathed a sigh of relief.

"Mo Xian's nephew lives up to the old man's expectations, and there is indeed a solution to the flood." He looked relieved, as if Merton had been able to find a solution to the flood, thanks to his order.

"Eldest grandson Yinren, the old man just heard with his own ears that you are going to ask for merit for Merton! Could it be that you forgot so quickly? Cheng Yanjin said on the side. In the entire court, as long as he dares to call the eldest grandson Wuji like this.

"Cheng Pifu, when did the old man forget, it's just that those who can work harder, Mo Xian's nephew has such a talent to learn, how about solving the sand control together, and then the old man will ask for credit for Mo Xian's nephew." The eldest grandson Wuji said.

Desertification control! Immediately, everyone's hearts were shocked.

Controlling the Yellow River must first control the sand, this is the wise saying that has been passed down from ancient times to the present, even if there is a flood discharge area, can solve the temporary worries, that is also a symptom but not a cure, with the continuous accumulation of sediment in the Yellow River, in the end, even if there is a flood discharge area, I am afraid that it will be discharged every year.

Thinking of this, everyone present couldn't help but shudder, and couldn't help but focus on Mo Jiazi again, although it was a shame for the important ministers of the Manchu Dynasty to put their hopes on a teenager, but after all, this is a big matter, and they can't take care of any face at this time.

"Mo boy, if you have an idea, just say it, as long as it is right, the eldest grandson Wuji will not give you credit, and the old man will personally give you credit." Cheng gritted his teeth and said, this matter is very important, if Merton can solve it, it will definitely be a great achievement, of course, he did not forget to stab the eldest grandson Wuji.

"Old man Cheng, you ......" Eldest Sun Wuji suddenly gritted his teeth in anger!

"Okay, you wait for the two of you to stop making trouble!" Li Shimin said angrily, Cheng Yanjin and eldest grandson Wuji glared at each other, and then shut up.

"Merton, just say what you pay attention to, even if you say it wrong, no one here blames you." Li Shimin encouraged...

Merton nodded, looked around, gritted his teeth and said: "Your Excellencies, you can know that my Mo family has risen again with the way of arithmetic, and now I will use arithmetic to settle accounts for your lords." ”

"As far as I know, the sediment of the Yellow River has been piled up year after year, and the riverbed downstream has been exposed to the ground, if the sediment of the Yellow River is piled up every five years, at least one finger of sediment is piled up at the bottom of the river, then ten years is the riverbed is raised by two fingers, a hundred years by twenty fingers, and a thousand years by two hundred fingers, that is, six feet."

Merton is not exaggerating, but somewhat narrowed, the bed of the Yellow River in later generations is generally three to five meters, and in later generations it is more serious as high as ten meters, which is called the Hanging River.

"In other words, in the future, the Yellow River may flow over our heads." Merton pointed to the top of his head and said slowly.

Immediately, all the ministers present felt a chill in their hearts, that kind of Yellow River is afraid that it will be even more unruly, and the harm caused will be even greater, and every year because the river water rises, strengthening the river is also a monstrous project.

"One might think, don't we still have a flood zone?" Merton asked rhetorically. "But the river water in the flood discharge area can not flow out at all, can only silt, so the degree of sediment siltation in the flood discharge area will be more serious, once or twice does not matter, if the flood is discharged ten times and a hundred times, I am afraid that the sediment of the Yellow River will be silted up in the flood discharge area, I am afraid that the Yellow River at that time will no longer be able to restrain it, and the disaster will be deeper."

Merton once said that in this world, anyone can deceive you, but only arithmetic can't, and Merton used these cold numbers to tell them a harsh truth.

The ministers present were not proficient in arithmetic, but this account could be calculated clearly with their fingers, and for a while, everyone couldn't help but sweat profusely, and the good news that they had received from the flood discharge area was suddenly swept away, they only knew that the problem of the Yellow River was very serious, but they did not expect the situation to be so serious,

Merton said heavily: "Of course, some people will say that this is only a few hundred years from now, or thousands of years from now, but if we don't control the Yellow River now, hundreds of years, thousands of years from now, what will be left to our children and grandchildren will be a hanging river flowing above our heads, hanging over our heads like a sharp sword, and how will our children and grandchildren look at us at that time." ”

All the courtiers' faces suddenly turned unnatural, and their eyes flickered.

"Mo Jiazi, which one said that he would not govern the Yellow River, if you have any ideas, then hurry up." Even a person like Cheng Yanjin was so arrogant that his back was cold, and he couldn't help urging.

"In fact, the Mo family does not have a method to control water and sand, but after the kid got the knowledge of Socrates, he vaguely had an idea." Merton Road.

"Socrates?" The ministers couldn't help but be stunned, they had also read the Socratic knowledge in the ink magazine, but they had never seen any way to control water and sand.

"One of the most practical ways of Socrates' pursuit of learning is to ask never-ending questions. Then let's ask the first question, where does the sediment of the Yellow River come from? Merton said slowly.

Everyone looked at each other, not because the problem was difficult, but because it was too simple.

"Of course, the sediment of the Yellow River is brought in by the water." Wang Yushi said angrily, the water is full of sediment, which is a characteristic of every river.

"So where does all this sediment-laden water come from? Could it be that the Yellow River is as muddy as it is from the source? Merton continued.

Wang Yushi suddenly concluded, he didn't know this question, he didn't know anything except the Confucian classics.

Cheng Yanjin shook his head and said: "The old man once went north to defeat the Xiongnu a few years ago, passed by Jiuyuan County, and once stationed on the side of the Yellow River, where the water of the Yellow River is still very clear. ”

Merton nodded and said, "The water of the Yellow River is still very clear in Jiuyuan County, but when you get to Luoyang, it becomes extremely turbid, so it seems ......"

As soon as Merton's words fell, he couldn't help but breathe heavily in the Tai Chi Hall.

"The problem is right under our noses!" Li Shimin's face was pale, they spent a lot of money to control the Yellow River downstream, but they didn't expect that the biggest root cause was in Guanzhong, and they didn't find the slightest discovery.

"It's dark under the lights!" Qin Qiong also sighed.
