The land of Guanzhong, the water network is dense, there are eight rivers around Chang'an alone, although only the Jing River and the Wei River can be regarded as big rivers, but the flow of the rest of the rivers is not small.

Therefore, even in the year of the great drought, Chang'an City will not lack water, and the surrounding Chang'an, Wannian, Lantian, Sanyuan and other prefectures and counties are the same, but some fields are far away from the river, and some are close.

However, in this Guanzhong land, the division of water flow is not very even, some places are full of rivers, and in other places, there are not necessarily rivers passing through for hundreds of miles.

After thinking about it, Lu Hanyang decided not to dig wells, and digging canals would be more advantageous, and with the help of Li Shuang's army, he should be able to save the water shortage crisis in many areas.

After all, using the sword qi rune seal can dig a canal for a long distance, although this kind of thing needs to be controlled by Lu Hanyang himself, but it is faster than that.

"First of all, find out the areas that are a little farther away from the river, but the terrain is relatively low, so that the water can flow through on its own." Lu Hanyang said this to Li Er after Li Er brought the map.

"That's easy!" Li Er and the military generals under him are all very talented, at least the terrain above the land of Guanzhong has an intuitive impression in their chests. They were able to quickly find out such a compound by looking at the map.

So one by one, the military generals are pointing out the country, and the generals must have an intuitive understanding of the surrounding terrain when they march to fight, and in these years, most of the generals under Li have walked all over the land of Guanzhong.

And those civil servants are not bad, although they are not as intuitive as military generals, but many of them are from the following states and counties step by step, when they governed the locality, they knew these very well.

So on the map, all the places that meet Lu Hanyang's requirements have been marked, most of these places are hundreds of miles away from the river, and no river passes through, but they are all in a straight line from the river.

"Here...... This is Gyeongju, which is about 100 miles away from the Malian River, but there is no river passing through it, the terrain is slightly low-lying, and there are no high mountains around it. It is suitable for the construction of aqueducts, but because the surrounding underground is a little deeper and there are rock formations, which cannot be excavated. Xiao Yu first pointed out a route, which was in the south of Gyeongju City.

"It should be possible to dig here, but you have to see it." Lu Hanyang said. One hundred miles, about five hundred or so sword qi rune seals are needed, and he is not sure how far a sword qi can be carved on the flat ground.

If you go directly underground, you can go 50 zhang deeper, but on the surface it should not be the same as going underground.

"And here, in Huazhou City, a hundred miles north of the road, from the Wei River and the Luo River are about the same, it is a plain, but there is no river to pass through, and it should be feasible to dig a canal. A hundred miles to the north is the Zhengguo Canal. I couldn't get close to either end, and I was stationed here, and in order to find water, I went to the village to find a well. Cheng Yanjin also said.

"Write it down here first, and then let's see!" The talisman seal in Lu Hanyang's hand was about 1,200, and his storage ring was full of this thing. Because there is nothing else to load.

This kind of brand is only the size of a finger, and 1,200 pieces are not very large, but it can be fitted. It's just that according to my current situation, the storage ring is still enough, but if you want to upgrade in the future, you don't know what to do.

The red-skinned gourd on the waist is now filled with wine, which the Tang Dynasty said was wine, but it was actually a drink. At most, the alcohol content is in the tens of degrees, and most of them are about the same as beer. And Lu Hanyang's current body, I don't know what's going on, anyway, I haven't been drunk for more than half a year.

Of course, Lu Hanyang didn't think about getting any liquor out, even if he wanted to, he wouldn't. Compared with others who can do anything after crossing, Lu Hanyang found that he really couldn't survive without a golden finger for the key.

Originally, the body was not strong, the speed was not fast, it could not make wine, it could not burn cement, it could not burn glass, it could not make a steam engine, and it could not even make a zigyuan plow. Of course, cowpox anti-smallpox, movable type printing, horseshoes and other rotten street things don't count.

But no matter what, drinking rice wine as water has become one of Lu Hanyang's daily lives now, picking up the red gourd and taking a big sip directly. Then continue to look at the map in front of you more and more thin lines.

"Which place has the worst water shortage? We must start from the driest places, or I am afraid that the harvest will really fail, and then the people will suffer! A minister reminded.

"No, we have to carry it out from near and far around Chang'an City, after all, we may only be able to open two or three canals this time, because none of them are a hundred miles long!" Lu Hanyang said.

"However, these places have not yet reached the end of the mountain, and the most serious ones, I'm afraid they can't wait!" When it comes to the life and death of such people, these officials will not be afraid of power, and of course, the voice of the official who said this still trembled a little unconsciously.

"It's not a question of whether the disaster is serious or not, because there is already a severe drought in those places, and even if the canals are dug, there is not necessarily much food that can be saved. Although the area around Chang'an City is not so serious, it can directly guarantee the output. Li Er stood up and said.

At this time, it is wisest to consider where to start and get the most benefits.

"Then the one in the north of Huazhou City will be given priority, where there is a plain and few mountains, which is very suitable for planting! So where is a large area of fertile land. Cheng Yanjin said.

"It's the same everywhere, anyway, this seat just has to make a move, you are sure where it is, this is more beneficial than digging a well!" Lu Hanyang said.

"According to Zhijie, the one north of Hwasju is the first, and then here, the one south of Gyeongju. This one is also surrounded by a low-lying basin, and there are many fields in between, and the damage is relatively light. Li Er's eldest grandson Wuji said.

"Okay, then let's do it, I will order the local government soldiers to dispatch and draw the line directly!" Li Er said and directly prepared for action.

"Hopefully!" Lu Hanyang said.

"This canal will be called the Immortal Canal in the future, no, if several are dug up, then it will be called the Immortal Canal No. 1, No. 2, and No. 3! Haha......" said a yellow-faced general.

"It doesn't matter what it's called, as long as you can hurry, don't let me wait for a long time!" Lu Hanyang didn't care.
