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

The man was brought in sitting in a chair, not only that, but his eyes were covered with a white silk, revealing only his smooth jawline.

After the man was placed on the ground, he raised his hand and saluted and said: "The grassroots are not good at behavior, please forgive me, Your Highness."

Before Liu Tan could ask, the sheriff of Wuyuan County said carelessly, "His eyes can't even see."

Liu Tan was dumbfounded, blind, and crippled. Such a person is good at water control?

"What's your name?" he asked.

"Xu Lin."

Surnamed Xu, Liu Tan had some doubts in his heart. He always felt that it sounded familiar, but he couldn't say it, so he simply put it aside and asked, "I heard that the governor of Wuyuan County said that you are quite insightful about water control?"

Xu Lin is neither humble nor arrogant: "Caomin has studied this way for twenty years, and no one in the world is better at this way than Caomin."

Liu Tan was startled, did he speak so loudly?Did you ever ask me that?

He asked curiously, "How old are you this year?"

Xu Lin replied: "Caomin is thirty one this year."

Liu Tan laughed and said, "You mean you have been controlling water since you were 11 years old?"

Several county guards nearby also smiled, Xu Lin didn't seem to care but said in a calm tone: "Yes or no, your Highness will know after a test."

Liu Tan restrained the smile on his face and said, "Treatment of water is nothing compared to other things. It can't be solved by pretending to be a ghost. If this king thinks it's not good, don't blame this king for driving you out."

Xu Lin raised his chin slightly: "Then who can be the referee? What if His Highness doesn't understand what Cao Min said?"

The people next to them couldn't help but gasped slightly. Although everyone was more restrained, they couldn't stand the crowd, which was very obvious at once.

Liu Tan smiled and said: "You haven't said how you know if I understand or not? What's more, no matter what the situation, I can only be the judge. If you can't convince me, it means that you don't have enough knowledge. You should continue to practice. "

What he said was a bit unreasonable, but Xu Lin nodded in good temper: "Your Highness is right."

Liu Tan asked someone to bring over the map and said, "If nothing else, let's start with..."

Liu Tan originally wanted to let him see the map, but when he turned around, he saw the white silk on Xu Lin's face stuck there—won't letting the blind man see the map be poking at his wounds?

Xu Lin seemed to know what Liu Tan was going to say, and said softly: "Your Highness said the name of the place, and all the rivers in the world are in the hearts of the grass people."

Liu Tan felt more and more strange, and couldn't figure out how a blind man did it, so he said, "Well, let's not start with the specific location, let's talk about the whole, and tell me your opinion."

In fact, Liu Tan already had a plan in mind for how to do it, and asking this person at this time was just to give him a try.

Xu Lin said: "If you want to change the flood in the Hetao, the first is trees, the second is water canals, and the third is lakes."

Liu Tan's eyes lit up, and although it was brief, he got to the point, Liu Tan asked again: "Tell me in detail."

Xu Lin said: "Since Your Highness has inspected the Yellow River, you should be able to find that the Yellow River itself carries a lot of silt, which makes the river turbid, and the accumulation of these silt over time will cause the river bed to rise, make the river flow, and even silt the river. , causing the Yellow River to divert, and because the Yellow River has a huge amount of water, every diversion will cause a disaster.”

Liu Tan said, "So we need to plant trees?"

Xu Lin said: "That's right, there are many trees along the Yangtze River, which can absorb a lot of water and fix the soil so that it won't be completely carried away by the water flow."

The people on the side were a little shocked, they looked at Liu Tan and then at Xu Lin.

For a moment, he didn't know whether he should be shocked because Xu Lin had the same views as Liu Tan, or whether Liu Tan had the same views as Xu Lin.

But either way is scary.

If Xu Lin is really as he said, then he is a genius for water control, and His Royal Highness the King of the North Realm is also very proficient in this area, which is even more unacceptable than Xu Lin.

First of all, how old is Xu Lin, and how old is the King of the North?Secondly, there are too many things in the Northern Realm King's Association. If it even manages the water, wouldn't it be said that if you mount a horse, you can fight wars, and if you dismount, you can rule the people?

The sheriff of Wuyuan County on the side was a little worried. He didn't know about water control, and he didn't understand what Xu Lin said, so he instinctively thought that Xu Lin was a liar. Well, flood control will cost a lot of money, and when the time comes, a large amount of money will be handed over, which is what Xu Lin wants.

In the end, I didn't expect that he was not a liar, but a bit of real talent.

After hearing what Xu Lin said, Liu Tan simply said, "You stay!"

Xu Lin had already prepared a long speech, but now he couldn't help but feel a little dazed after listening to it: "Your Highness, don't you want to continue listening?"

Liu Tan smiled: "If you can say this, it means that you have indeed done research, and you don't need to waste your time. If you have that time, it's better to study how to solve the problem in the shortest time."

Xu Lin was silent for a long time before he said: "Your Highness is really quick to speak. Since this is the case, the grass-roots people don't give a shit. If His Highness wants to be fast, he can send people to plant plants and dig the lake at the same time."

"Huh?" Liu Tan's thinking was different, and he asked curiously, "Why didn't you dig the canal first?"

Xu Lin explained: "The canal needs to be accurately calculated, and the construction time will be very long, which does not meet the requirements of His Highness to solve it in the shortest time."

Liu Tan said with a smile: "Isn't it enough to dig a lake? It's even more difficult to make a lake?"

"But you can choose a suitable oxbow lake to expand." Xu Lin tilted his head slightly, as if thinking: "Wait until the lake is formed before diverting water from the lake, which is safer than diverting water directly from the Yellow River. If there is water, there will be lakes as a buffer.”

Liu Tan was stunned for a moment, thought for a while and said, "What you said makes sense, but I didn't expect that. Then what?"

Xu Lin paused for a moment, as if he hadn't expected Liu Tan to admit his shortcomings so readily, and after thinking about it, he said, "It's best to plant plants around the lake and move them to the side of the river, in case the plants are not yet fully grown. It was also destroyed by the diversion of the Yellow River."

Liu Tan propped his chin and said, "Well, I haven't really thought about what kind of trees are suitable for me in the northern border country."

Xu Lin immediately said: "You can't use trees!"

Liu Tan was a little surprised: "You can't use trees? Why? What can you use if you don't use trees?"

Xu Lin said: "It's not that it can't be used, but it's not used at the beginning. The growth of trees is too slow, and it takes too long to achieve the purpose of soil consolidation in a short period of time. Therefore, it is best to choose plants that are easy to grow at the beginning."

Liu Tan: You have touched my blind spot of knowledge.

He leaned slightly and asked, "Then do you know any plants that can grow quickly?"

Since Xu Lin can say this, it means that he must have thought about it, and maybe he has the answer.

Sure enough, Xu Lin said, "Yanmu."

"Salt wood?" Liu Tan was slightly taken aback, and couldn't think of what it was for a while, but... since it's called wood, isn't it a tree?

Xu Lin heard his doubts and said: "Saltwood is very special. Its seeds survive for a short time, but only need a little water to germinate within two hours. It is the fastest germinating plant among the plants that the grass people have seen. plants, and are not highly dependent on water, and do not require a lot of manpower to irrigate on the edge of lakes or dry rivers."

Liu Tan frowned, feeling that this plant sounded familiar.

But Xu Lin turned his head and listened, and found that Liu Tan hadn't spoken, so he said, "And another advantage of salt wood is that there is a very precious medicinal material that will parasitize on it."

Liu Tan asked, "A very precious plant? What is it?"

"Goblin."
