I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Sang Qian now saw that Liu Tan was in a very peaceful state of mind, so he saluted Liu Tan honestly and said, "I see your Highness."

Liu Tan took a serious look at him, and found that in less than a year, Sang Qiangeng was completely different when he first came here.

When Sang Qian was in Chang'an, he was also an aristocrat with red lips and white teeth, but now his skin has become wheat-colored, his previous dandy habits are gone, and he looks much more down-to-earth, and his eyes are brighter than before.

Liu Tan took a look at the county city of Yang County in Xi'an, and had to say that this city was much better than the one in Shuofang before.

He took a closer look and found that the street was clean and tidy, and the status of the pedestrians was okay. These people should recognize Sang Qian, and they looked like they were going to come up to say hello, but when they saw Liu Tan walking in front of him Not too daring.

It was also thanks to Liu Tan that he left the elite group outside and brought a dozen or so people into the city, otherwise the common people would be scared away.

Liu Tan asked: "I've been here for a long time, right? What do you think?"

Sang Qian said with emotion: "I used to think that I was born in a family of officials and eunuchs, and grew up in Chang'an. My vision is very accessible. I didn't know it until I got here. There are still many things I don't know."

Liu Tan smiled: "Do you think the contrast is too big? Chang'an is prosperous, and it's easy for people to think that the cities and people in the world are like this. Even if you know it, you can't imagine it. Once you become a county guard, your future road will be much broader. .”

There were no mandatory regulations in the Han Dynasty, but after the Han Dynasty, even in the middle of the Tang Dynasty, if you wanted to enter the center, you had to go to a local office, and some even had to start from the county magistrate a little bit.

Sang Qian was not too convinced at first, but now he also felt that it was not a bad thing, so he just asked, "Why is your highness traveling in such a hurry this time?"

Liu Tan said: "Do you have a map here? You don't need a detailed map, as long as you have water systems and irrigation networks."

Sang Qian froze for a moment: "Irrigation network?"

Liu Tan raised his eyebrows: "I heard from the Prime Minister that there will be little rain this year, and I'm afraid the harvest will be poor."

Sang Qian's expression immediately became worried: "So it's not just Xi'an Yang?"

Liu Tan asked, "How does it compare to last year?"

Sang Qian said, "It's a little less than last year."

Liu Tan frowned: "Why didn't you report it earlier?"

Sang Qian was stunned: "This... Could it be that His Highness wants to ask for rain?"

Liu Tan:? ? ? ?

Sang Qian immediately silenced Liu Tan, who had a bad look on his face. It was strange to say that although he was not a bully in Chang'an, he had a bad temper, and sometimes he didn't even listen to his father's words at home. .

As a result, after arriving in the northern border country, he was very afraid of two people. The first was Huo Guang, the Prime Minister of the country, and the second was His Royal Highness the king of the northern border.

In fact, thinking about it carefully, the King of the Northern Realm seldom loses his temper, and he doesn't understand why he is afraid. In the final analysis, it is probably because Liu Tan's stabbing of the former county guard was so quick that he left a shadow in his heart, and he was afraid that he would also be stabbed at any time. Alright.

Liu Tan resisted the urge to roll his eyes: "Of course we have to find a way to solve it. If you guard the Yellow River, there will still be water shortages. Haven't you thought about how to divert water?"

Sang Qian said with a bitter smile: "Of course I thought about it, but... the Yellow River is too difficult. Even if the diversion canal is dug, it will not take long. If it is used this year, the water may not be diverted next year, and the Yellow River may even be diverted here. Wash away the original farmland, and over time..."

Liu Tan nodded: "Understood."

It's similar to what Huo Guang said, the only difference is that the common people have actually thought of a way, but Huang He has a bad temper and a high IQ, if everyone thinks of a way, the other party can destroy a way.

After arriving at the county mansion, Sang Qian brought over the map, which was basically re-mapped with a new method. Although it was not so detailed, it was still readable.

Liu Tan looked at the oxbow lakes all over the territory and said: "These lakes are the best to use, and the second is the Yellow River itself. There must be a reason for the frequent diversions, and we can only solve it when we find it."

Sang Qian stood aside and didn't dare to speak out. Liu Tan's words were too arrogant, and he was about to solve the problem of the Yellow River. Let alone Sang Qian, he didn't dare to say anything downstream.

Liu Tan collected the map and looked up at Sang Qian and asked, "How is it? Would you like to walk around with me?"

Sang Qian was a little surprised: "Your Highness is going to take your ministers on a tour?"

Liu Tan said: "The Yellow River is not independent. Even if it needs to be managed, everyone must work together. Otherwise, why should I come out? What if the upstream Shuofang City solved the problem and you have floods here?"

Sang Qian thinks about it, even if he doesn't care about other counties, but everyone is a member of the Northern Kingdom, and if anyone only cares about himself and annoys the Northern King... then he really thinks he has lived too long .

Sang Qian honestly handed over the matter to the people below to go on tour with Liu Tan.

In fact, Liu Tan didn't go to many places, that is, he walked through the counties located on the banks of the Yellow River. Except for Xi'an Yang County, Wuyuan County, Yunzhong County, and Dingxiang County, the remaining Xihe County and Although Shangjun is also on the edge of the Yellow River, the situation is not very serious. Compared with these counties, the harvest is not bad.

Liu Tan didn't go there at all, mainly because Xihe County and Shang County were already very close to Chang'an. He was afraid that Chang'an would get news if he walked too far. To go or not to go?

It was the first time for Liu Tan to take four county guards on tour, and it was a novelty.

It's a pity that except for Sang Qian, the other three county guards exhausted their old darlings every day, carefully serving Liu Tan, not to mention the iron-eating beasts around him.

Serving Liu Tan is worried that the other party will not go well, so he draws his sword to give them a heart-warming comfort. Serving the iron-eating beast... Then it has nothing to do with Liu Tan. What they are worried about is that the iron-eating beast is unhappy and kills them.

You must know that after the sheriff of Dingxiang County on the far side went on a tour, they once watched the iron-eating beast run towards a wolf when they were stationed in the wild, and then slapped the wolf to death with three slaps.

Seeing that they were chilled all over, when the iron-eating beast came back, except for Sang Qian, the remaining three county guards exuded a weak, pitiful and helpless aura.

Especially when Liu Tan actually slapped the Iron Beast's head to educate him, he almost didn't bring it up.

They finally understood why there were rumors that the king of the northern realm had descended into the world. If it hadn't been for the descending of the immortal god, how could they have subdued such a beast!

Liu Tan didn't think that Gun Gun shouldn't kill wolves. These days, wolves don't mean to protect animals or even cause a flood. He just doesn't want Gun Gun to eat wolves. What kind of germs would wild animals bring?

If Gun Gun is obedient and doesn't eat, then let it play as it pleases.

Sang Qian looked at Liu Tan's education and couldn't help but smile and said, "Your Highness is teaching children?"

The remaining three county guards looked at him like a warrior, but they didn't find it abrupt. After all, Sang Qian's identity was there, and the king of the northern border was not really a madman. Absolutely not life-threatening.

Liu Tan couldn't help complaining, "This is harder than a child."

However, Gun Gun's son, who was complained by him, offered his filial piety the next day - as soon as Liu Tan woke up, he heard Miao Rui say that a wild goose, a fox, and a wolf were neatly placed at the door of his camp. .

Because it was dragged over by rolling, they didn't dare to move, they could only wait for Liu to discuss and make a decision.

After Liu Tan got up and walked to the door of the tent, at first glance, he thought that rolling was probably an obsessive-compulsive disorder, and he was still posing according to his body size from small to large!

Liu Tan said melancholy: "The wild goose... take it first, and leave the skins for the remaining foxes and wolves, and you can deal with the meat as you like."

He wouldn't know how to eat, but at least it was because of his son's filial piety, he was afraid that he would throw it all away and squat by his bed, beeping, and his life would not pass.

It was also because of this that Liu Tan praised it against his will when he rolled over to show off his cuteness.

After complimenting him, he took Gun Gun to the central account, called several county guards over and said, "Okay, we've walked the entire Yellow River in the past few days, so let's talk about what you think."

Liu Tan said that the several county guards were serious in an instant. I have to say that after following the king of the north, they changed a lot in their opinion of the king of the north. At least before that, they never thought that a prince and king could endure hardships like this.

Even if his conditions are the best, wouldn't it be good for him to eat, drink and have fun in the palace during this time?

Why do you have to run out to eat and sleep in the open?

But it was precisely because of this that they realized that Liu Tan was serious about water control.

At this time, everyone was also thinking seriously, and Sang Qian said: "The first thing to solve is the problem of changing the course of the Yellow River. If the Yellow River can flow through the same channel as the Yangtze River, then we can safely divert water for irrigation, and even many Food can be grown in places that were not even dared to use as arable land.”

The sheriff of Wuyuan County said seriously: "It's what you want, those places are very fat."

Wuyuan County is the closest to the Yellow River, and there is only Shuofang City that can be compared with it. As a result, because a large area of ​​the Yellow River cannot be used, the governor of Wuyuan County has been distressed for a long time.

The magistrate of Yunzhong County smiled bitterly and said, "Everyone understands this truth, but the problem is that the Yellow River will be diverted. That's God's will. Who can control it?"

As soon as he finished speaking, he was stabbed by the sheriff of Dingxiang County. After he turned his head in confusion, he saw the eyes of the sheriff of Dingxiang County drifting towards Liu Tan. Immediately shut up honestly - almost forgot that there is such a fairy.

Sure enough, he heard Liu Tan chuckle and said: "There is a saying that man can conquer the sky. I hope you can remember that since when it comes to the Yangtze River, the Yangtze River seems to rarely change its course, even if it is not too violent, then we can do it." Comparing the difference between the Yangtze River and the Yellow River, this may also solve the problem."

Everyone was stunned, and Sang Qian looked at Liu Tan blankly and said: "But... the place where the Yangtze River passes is completely different from the place where the Yellow River passes. How... how does this compare?"

The geographical form is different and the climate is different. How can it be possible to copy the situation of the Yangtze River?

Liu Tan said directly: "It's not impossible to compare. The first is the river course. Why doesn't the Yangtze River change its course so frequently? First of all, there is a lack of natural waterways. If you analyze it carefully, you can see that the places where the Yellow River flows are relatively short of water. , or in places with very little precipitation, the vegetation is sparse, especially in the eyes of desertification on our side, which leads to sedimentation, can you understand?"

Liu Tan has tried his best to use unprofessional terms to explain in this process, but many words may appear in this era for the first time, so he can only ask questions while explaining.

The sheriff of Wuyuan County on the side said thoughtfully: "This... I seem to have heard someone say it."

Liu Tan was surprised: "Who is it? Where is this person?"

Those who can see this matter thoroughly show that they have a good understanding of the Yellow River, and they may have studied water control!
