[Big brother, it's useless to just stick to it, you still have to build, this is the way to do it once and for all!] ]

Lin Meiyi's words were like a spell, lingering in Lin Dalang's ears all the time.

So much so that when I rode a horse, I almost rode into a ditch.

"Lin Dalang, what do you want!" Qinglan hurriedly rushed forward and pulled him, and the horse was back on track.

Lin Dalang was also taken aback, and was taken aback by this, he finally came back to his senses, stopped the horse, looked at Qinglan, and asked:

"You say, if we dig a ditch here, can we do it?"

"What did you say?" Qinglan didn't hear clearly, the wind was too strong.

Of course, he suspected that he was hallucinating.

Lin Dalang still knows how to think about these things?

Didn't his brain just know how to fight?

Lin Dalang knew that he heard it as soon as he saw Qinglan's appearance, and said angrily: "Lao Tzu said, if we dig a ditch here, it is feasible?!" ”

Qing Lan heard it clearly this time, and wordlessly dug into her ear, which was about to be roared out, and frowned: "Who gave you the bad idea?" In our place, where the mountains are high and the roads are far away, how can we build the canal? ”

A few years ago, His Majesty ordered the construction of the Wei Water Canal to divert the water from the east to the central part, but it has been seven or eight years, and it has not been repaired yet, so you should dig a pit and do it?"

Saying that, Qing Lan couldn't hold back her curiosity and asked, "Who told you this?" ”

Da Lang glared at him, "No one, Lao Tzu thought of it himself!" ”

"Really?" Lin Dalang asked again without giving up.

Qinglan shook her head firmly, "It's not a day's work to repair water and open a canal, instead of thinking about how to repair the canal, you should think about how to dig a few more wells." ”

Hearing this, Lin Dalang couldn't help but be disappointed.

But then again, because this matter is so difficult to do, if he solves this big problem, wouldn't he be able to get an official and become a knight?

The eldest sister is right, if you want to be an official, you will be a big official, what does it mean to be a junior general in a small place here?

If you want to do it, you will be a big official like a general, and it is best if the border war stops, and he can be recalled by His Majesty to Beijing as a Beijing official.

Even if you can't be a Beijing official, it would be nice to stay here and be a general.

That big sister can walk sideways in Taiyuan County! It's not majestic!

When the time comes, you can use a few electric lights if you want to, and you can eat as many vegetables as you want, and you will no longer have to hide and live aggrieved like this.

How to solve the problem of water in the city?

Lin Dalang turned his head to look at Qinglan, "Didn't you say that there is everything in the book?" General Ben ordered you to go back to reading books immediately, and you were limited to three days, and think of a way for General Ben to come out, and if you can't think of it, you can come to see you! Lao Tzu still doesn't believe it, he can't dig a ditch! ”

Qinglan was dumbfounded: "Lin Shijun, you can't be crazy!" ”

Lin Dalang looked at him coldly, "Your Majesty has made a truce and asked us to recuperate here, but the water in Yang County is inconvenient, how can we recuperate?" As a courtier, I naturally have to share my worries for Your Majesty, what? Do you have an opinion on His Majesty's will? ”

Qinglan is completely convinced, you are Lin Dalang, your ability to follow the general has not risen, but the more you talk about it, the more you talk about it!

Qing Lan turned over and dismounted, bowed, gritted her teeth and shouted, "Subordinates obey!" ”

Saying goodbye again, Qinglan returned to the city on horseback and began to consult books related to water conservancy.

It doesn't matter if you don't look at it, the more you look at the skull, the more painful it becomes, Qinglan feels that sooner or later she will be killed by Lin Dalang.

He flipped through the ancient books, and also borrowed a lot of relevant books from the officials in charge of the fortifications in the city, and the results of the books all said that digging rivers and ditches, at least three or five years, more than ten or twenty years, this is a big project, the emperors of all dynasties began to plan from the beginning of their accession to the throne, and some of them failed to complete the planning during their lifetimes until they died.

What does this mean?

This shows that this matter is as difficult as the sky.

However, Qinglan is not completely without gains.

He unexpectedly saw the topography and water conservancy survey map of Taiyuan County, although this was already the data drawn a few years ago, but now it is also very useful.

It turns out that the tributary of Yang County flows down from the north of the Fen River, Taiyuan County is high in the north and low in the south, and there are many mountains and forests in the east and basins and plains in the west.

And Yangyang, just in the northwest, the mountains and rocks here are relatively gentle, the geology is relatively soft, suitable for land reclamation.

Looking at the terrain difference between the main trunk of the Fen River and the branch of Yang County, the difference between the two places is 500 meters, the main trunk is high, the branch trunk is low, and the canal is more convenient than other complex terrain.

Qinglan took a breath of cold air, and somehow, she was also a little upset.

Continuing to read the experience left by his predecessors day and night really asked him to find a feasible solution.

Diversion for irrigation.

Take advantage of the height difference between the two places to direct water from high to low places.

But such land cannot be too flat and must be built on slopes for effective irrigation.

The fertile fields near Taiyuan Fucheng are using this method.

Or the Pitang method, which is to store water in a naturally formed low-lying area, with high walls on both sides to form a reservoir to store water, and then open a canal from the ground to use the high water pressure to introduce water into the farmland for irrigation.

However, a large amount of rainfall is needed to achieve the purpose of water storage, and the northern part of Taiyuan County has less rainfall, but the former method of water diversion irrigation is more effective.

Thinking of this, Qinglan hurriedly grinded the pen, and at the last moment of the three-day time limit, she wrote out the feasible plan and handed it to Lin Dalang.

"Good fellow, you can do it!" After reading this illustrated and well-founded plan, Lin Dalang patted Qinglan's shoulder with satisfaction.

Qinglan didn't close his eyes for two nights in a row, and he was already weak, so he waved this slap down, and almost sat on the ground with his ass.

Finally stood firm, and hurriedly took leave, "General Lin, for the drawing you wanted, my subordinates haven't closed their eyes for two nights, and I ask you to be kind and let your subordinates go back to rest for a while." ”

Qing Lan gritted her teeth when she spoke, Lin Dalang didn't care at all, his eyes were glued to the drawings, he didn't even look at Qing Lan, and waved his hand again and again, "Go ahead, go ahead, if the general is approved, I will give you the first credit!" ”

Qinglan said goodbye, so sleepy that she couldn't open her eyes, and stumbled home and fell asleep.

Lin Dalang looked at the drawings for a while, and then came to Lin Meiyi with the drawings and asked her to take a look, which was quite showy.

Lin Meiyi looked funny, but when she saw that her brother took her words to heart, she was happy, so she didn't say anything, took the drawings and looked at them, and was quite surprised.

The plan made by Qinglan is really good, and all aspects are considered very clearly.

It's just that the construction time is a bit long, at least a year and a half.

However, thinking of the current backward construction conditions, it can be understood.

Lin Meiyi nodded and returned the drawings to the eldest brother.

"How?" Lin Dalang immediately asked eagerly.

Lin Meiyi nodded, "It's really good." ”

Lin Dalang was happy, "Big sister, just take a look." ”

After saying it proudly, he took the drawings and went straight to the camp.

Seeing Zhen Huaimin, without saying a word, he presented the drawings with both hands, "General, let's dig a ditch together!" ”
