All of Sook Yun's rooms are open-plan and there are no partitions between the areas. Li Dequan knows Kangxi's preferences very well, and he also knows Shuyun's status in Kangxi's mind. So when reporting to Kangxi, there was no taboo. But Shuyun, who was sitting on the sofa and eating bird's nest not far away, listened to it.

It turned out that the river governor Jin Fu sent someone to report that according to this year's rainfall, the Yellow River is likely to flood again.

After Li Dequan reported, he glanced at Kangxi's face and quietly retreated. Kangxi sat motionless on the chair in the study with a calm face, and sighed softly after a while. Then it seemed to ask Shuyun, and it seemed to say to himself, "Alas! I really want to govern the country well, but whether it's those thieves or this God, why do they oppose me everywhere?"

Shuyun sat quietly on the sofa and listened to Kangxi's emotional words. A hand gently stroked the bulging abdomen, and his face was calm. ~ It's okay, it should be okay at this time. ～

Then Shuyun shrunk her neck and said weakly, "Xuan Ye, can I call you that?" ”

Kangxi, who was depressed, was suddenly interrupted from his thoughts, and glared at him, "Why do you look like you are angry, I have already said that you are called like this, it is you who keep calling the emperor and the emperor all day long, and now you are bothering me with this matter, what do you want?" ”

Kangxi stopped complaining, and began to yell at Shuyun.

"Aren't people afraid of disobedience?"

"Huh, it's proper now?"

"That person really wants to call you by name right now."

Kangxi was puzzled, "Why?" ”

Shuyun glanced at Kangxi, and the mosquito said, "Do you really want to say it?" ”

Kangxi's ears were old, and he stared. Roared, "Say it quickly." ”

"What, is it okay to tell a lie?"

"Hmph. You tell me? ”

"Then I'll really say it, don't be angry when you hear it."

Kangxi didn't squeak. but glared at Shuyun fiercely.

Shuyun shrank her neck and said cautiously, "Don't I feel that if you call your name, it looks kind, and if you say the wrong thing, it's easy to get forgiveness, right?" "Hey," Shuyun then smirked twice.

Lao Kang was so angry by Shuyun's words that he wanted to slap the table, his hands were raised, he looked at Shuyun's high belly, put it down with hatred, and shouted, "You are telling the truth, you are originally my woman." If you don't call your name, you won't kiss? What kind of mess are you thinking about all day long? Say anything quickly. ”

Shuyun looked at Lao Kang with tears in her eyes and said, "I saw that you were quite popular, so I wanted to talk about river affairs, people have studied hydraulics." Then he secretly glanced at Lao Kang, and said weakly, "Is this considered a harem government?" ”

Lao Kang pouted with disdain and said, "It's up to you, and you're still in politics." Do you have this brain? ”

Shuyun first patted her chest with her chubby hand and said, "It's okay if you don't count, it's okay if you don't count, hehe." "Huh? That's not right. Then he glared at the pair of squinting eyes, puffing out their cheeks like big frogs. just looked at Lao Kang straight and shouted, "Are you saying that I'm stupid?" ”

Lao Kang looked at Shuyun's puffed appearance. I think it's so cute. also knew that she was concerned about herself, and she didn't really get angry with Shuyun, but she was a little unhappy when she heard about the possible flooding of the Yellow River. But when I thought of Shuyun's grievance just now, I couldn't help but care about my own appearance. Kangxi felt very intimate. So he changed his angry face, walked over with a smile, sat on the sofa and hugged Shuyun and coaxed, "Okay." Don't be angry, tell me about the river. ”

Shuyun Zhengse said, "Before you say that." I have to tell you, I'm smart. I've learned a lot of subject knowledge and made a lot of inventions, so you can't underestimate my wisdom. ”

Kangxi was made to cry and laugh by Shuyun, and wanted to laugh at Ha Lu Ha, but under Shuyun's serious and positive expression, it was not easy to laugh out there, it was too shocking, so the whole face was suffocated. But the deep sense of powerlessness at the beginning is gone.

The helpless Kangxi had no choice but to kiss Shuyun heavily on the forehead, and coaxed a child, "Yes, my Yunyun is the smartest." Tell me about the river. I'm still waiting to hear it. ”

Shuyun recalled the information about the Yellow River in her mind, and then said, "The Yellow River is the one with the largest sediment content among the rivers in the whole world that I know. If we want to control the Yellow River at its roots, we must first understand the Yellow River. ”

Then Shuyun got up and went to get paper and pen. "The source of the Yellow River is located in the Yaradazhe Peak of the Bayankala Mountains on the Qinghai-Tibet Plateau, and its main stream runs through Qinghai, Sichuan, Gansu, Ningxia, parts of Mongolia, Shaanxi, Shanxi, Henan, Shandong, and finally empties into the Bohai Sea. After Shuyun finished speaking, a big "several" word jumped on the paper, and some geographical names were distributed on it.

Kangxi, who was still laughing, also straightened his face at this time. Kangxi didn't think that Shuyun would say anything useful. Shuyun is often studying some messy things, although some of them are also very useful, such as high-yield grain varieties and glass, but Shuyun gives Lao Kang the feeling that there is no longevity, all at once in the east and all at once in the west. Most of the time, it's just a mouthful. People too, seemingly shrewd, are actually a little confused.

But after all, Shuyun brought up this topic tremblingly out of concern for herself, and she was worried about what harem was doing politics, but she could even tell the truth to herself, such as "calling your name is kind, and it is easy to be forgiven for saying the wrong thing." Hehe, it makes people laugh just thinking about it. So Kangxi couldn't bear to refuse her, and when he heard her talk about it, he regarded it as coaxing her to play, and made her happy. Didn't the imperial doctor say that "if a pregnant woman is in a good mood, it will be good for the body and the fetus." However, he never expected that Shuyun would know so much about the situation of the Yellow River, and maybe he could really give some useful suggestions on the issue of the Yellow River governance.

So Kangxi changed his attitude, looked at the piece of paper on the table with a serious face, and asked, "Shuyun, how can you know so much about the Yellow River?" ”

Shuyun smiled a little proudly: "Now that I know that I'm amazing, right?" I just told you that I studied hydraulics. When I was a child, he stopped, and then sat for a moment as if he was reminiscing about something. At this time, Lao Kang was also very understanding, and he didn't rush to ask, but just grabbed Shuyun's little hand and patted it lightly as if comforting.

As if interrupted by him, Shuyun looked back at Lao Kang with a little worry on his face, smiled slightly, and said, "Don't worry. Alas, when I thought of it when I was a child, I saw that there were many people who had lost their homes because of the flooding of the Yellow River, begging for food one by one, and the water and fire were ruthless, which was really miserable. At that time, I began to pay attention to the Yellow River, and later studied hydraulics with missionaries, during which I studied the information about the Yellow River, and after I arrived at the Holy See, I studied this knowledge again. I just thought that if one day the imperial court wanted to govern the Yellow River, it would also be able to help a little. ”

Lao Kang smiled softly and hugged Shuyun and said, "How can my Yunyun be so kind!" But why do you think about helping the court, will those "adults" listen to you? Or will you know that Lu Dao will become my woman at that time, huh? After a while, Kangxi began to make fun of Shuyun restlessly again.

Shuyun was stunned for a moment, then scratched her head in embarrassment and smirked twice, "Huh?" Why didn't I expect people to pay attention to me? Then he snapped Lao Kang and said, "Oh, you're really, you're going to hit people." Anyway, I'm applying what I've learned now, right? ”

Old Kang Ha Da Lu smiled and said, "Yes, you are smart, you can predict the prophet, okay." Tell me about the Yellow River. ”

So Shuyun, at the urging of Lao Kang, began to say again: "The average runoff depth of the Yellow River is 79 meters. However, the volume of water is not very large, bringing together more than 40 major tributaries and more than 1,000 streams, the lack of lakes on both sides and the high riverbed, and the few rivers flowing into the Yellow River, so the area of the lower Yellow River basin is small. The whole Yellow River is from high to low direction, the terrain is uneven, the slope is steep and the ditch is deep, the river channel is flat after entering the downstream, the water flow is slow, a large amount of sediment is silted, the riverbed is 4~5 meters above the ground, especially when it flows through the Loess Plateau, where the soil erosion is serious, so it is entrapped with a large amount of sediment, which is also the main reason why the Yellow River floods all year round and is extremely difficult to control. I calculated that there are more than 200 million mu of cultivated land in the Yellow River basin, together with the downstream Henan and Shandong river areas, and the people living on such a vast area of land basically rely on the Yellow River for water and irrigation. There is a saying called "hanging river on the ground", which the emperor must have heard, that is, "the trough is higher than the beach, and the beach is higher than the ground of the back river", and the Yellow River is the most typical hanging river, and I believe that if it is not controlled and controlled, this situation will be further exacerbated with the increase in the population of the Yellow River Basin. The Yellow River can be said to have given birth to human beings and civilization in China, but it has also brought endless suffering and disasters to the people here. In fact, it can also be said that all this is caused by human beings themselves. ”

Kangxi heard this statement for the first time, so he interrupted Shuyun and asked puzzledly, "Why do you say that it is caused by human beings?" As early as before the summer, there was "Dayu to control the water", which shows that the Yellow River has been flooding often since ancient times? ”

Shuyun Road" the key problem lies in this, "Yu Gong" said: "Yu farewell Jiuzhou, with the mountains and rivers", indicating that the soil erosion in the Loess Plateau area at that time has been very serious, a large amount of sediment into the Yellow River, so that the siltation of the lower reaches of the Yellow River is becoming more and more serious, people will have the idea of "following the mountains and rivers" (that is, with the mountains to guide the stagnation, dredging the upstream of the river). So what was the Yellow River like before that, as far as I know, the earliest Yellow River was not what it is now, when the Yellow River was clear and its banks were full of forests and grasslands. The climate is mild, especially suitable for human habitation. In particular, the Central Plains in the middle and lower reaches of the Yellow River, that is, Henan, Shanxi, Shandong, Hebei, Jiangsu and other places where the Yellow River flooding is most serious. ”
