Li Meng rushed all the way up to the city gate, and by the light before the setting sun, he looked far away, and saw nothing but the camp that had begun to be seen on the high ground in the north.

"Isn't there a dam? Where? Li Meng asked.

Wang Fang glanced at Li Meng, frowned and said, "...... Just after that high ground...... A lot of scouts were damaged, and Fang found out about it......"

By building a camp to shield it?

No wonder there's no trace here......

But would it be useful to build dams?

Li Meng suddenly remembered that it was said that there was a thing called Yutu, which could help to understand the geography of mountains and rivers, and hurriedly asked someone to find the map of this place from the warehouse of Sucheng, and then couldn't wait to spread out this map of Sucheng drawn on the silk......

The towels and silks used to draw the map are a little yellow, and it is obvious that there are some years. This kind of thing, almost every county has a copy, some of the surrounding major mountains and rivers and important roads have been drawn, but as a fine tradition in China, "Yihui" is a very important skill.

Li Meng: "......"

Wang Fang: "......"

Li Meng looked at Wang Fang, and Wang Fang also looked at Li Meng, both of them had the same expression on their faces.

“…… Is this Awagi? Li Meng pointed to the jagged box in the center of the map.

Wang Fang clicked on the small words on the edge of the box, and then clicked on the crooked pattern on the side and said, "...... Should be...... But what is this drawing? Is it a mountain? Is there a mountain near us that looks like this? This is Luoshui, right? No, this is supposed to be the old straight? ”

Li Meng: "......"

The map is not big, but on such a small silk, it is necessary to draw the geographical situation and show the painter's superb artistic processing ability, so that the so-called map scale is gone......

The painter carefully combined freehand and abstraction to sketch a landscape ink painting near Sucheng, but this wonderful painting art became an obstacle in front of Li Meng and Wang Fang.

Li Meng compared the map up and down to the terrain outside the city for a while, and then said, "...... This, I said, you see this side should be facing north...... It's still ...... this side."

Wang Fang: "......"

Li Meng: "......"

The problem now is that although Li Meng and Wang Fang have taken the map in their hands, they are completely inconsistent with the terrain in front of them, and they don't know where the Feiqian army is camping is in this map......

Li Meng angrily crumpled the map into a ball, then threw it at his feet, and said, "What the hell is the drawing!" It's not as useful as Lao Tzu's direct look! ”

But having said that, if you really want Li Meng to see it, you may not be able to see it.

When a dam is built, the intercepted water will naturally flow down when the dam bursts, but whether it will flow to Aiso, whether it will cause damage to the castle, whether it will affect the army in the castle, these things can be seen with the eyes like this......

At least not Limmond.

Of course, neither will the king.

It's definitely not okay to ignore this matter, but it's too rash to go out of the city to attack or destroy it like this, and the problem now is that the two of them won't want to, at least they have to find a way to do it, otherwise how to make a strategy to deal with it at the moment?

Li Meng and Wang Fang were a little worried for a while......

At this time, Fei Qian didn't have so many troubles, he explained the things in the barracks to Ma Yan and Zhao Yun, and he and Xu Shu Xun Chen came to the place where the dam was built on the hillside.

Building a dam to intercept Luoshui is Xun Chen's strategy, sometimes Fei Qian has to admire these guys, his head is really bright, and after surveying the terrain of Sucheng, he can deduce the corresponding solution from it......

The point is that such a strategy is very difficult to crack.

Fei Qian watched as the soldiers threw the felled trees one by one onto the wooden stakes on the riverbed, and then threw stones and other stones into the middle of the river using the cover of the branches, and the water flow gradually shrank under such circumstances, even if the scouts in Aisoki were not aware of it, the muddy river water and the gradually decreasing water flow would attract the attention of the other party......

Of course, if the other side is so stupid that they can't even notice this, then there is really no cure.

Do you really want water to irrigate Sucheng?

Hey, hey, hey......

How many cubes does that need?

Although Fei Qian is not in the civil engineering series, he still knows a little about this kind of thing, and according to the current situation, if he wants to use water to destroy Sucheng, it is actually impossible for these soldiers under Jinping to be under him.

It's not that it can't be done, to achieve that effect, the amount of water cubes in the reserve must be large enough, but that large amount of water in turn requires the dam's interception ability, so it is impossible to do this with the troops at hand.

If there were tens of thousands of people to support the civil engineering work, it would take a long time, and now Fei Qian didn't want to delay too much time here in Sucheng.

Obviously, Sucheng is the first line of defense of the Xiliang soldiers, and it is the most important line of defense in the direction of Feiqian.

The strength of Li Dao and Guo Yan can be estimated, even if the original forbidden army and garrison in Chang'an City are absorbed, it is not possible to use it directly with confidence and boldness, so it must still be the main defensive force of the Xiliang soldiers, so the current situation is equivalent to the Xiliang soldiers have dispersed the original forces......

This creates some opportunities for Fidive.

"Yuruo, how long do you estimate it will take to build this dam?" Fei Qian asked.

Xun Chen said: "About three days. ”

Fei Qian nodded and said, "Just let the war horse rest and recover its strength...... Then I will lead the cavalry to the south the day after tomorrow? ”

Xu Shu said: "According to a certain opinion, if the prince is in the early morning of the day after tomorrow, it is more appropriate to leave before the sky is bright......"

Xun Chen thought about it, nodded and said, "Yuan is straightforward. ”

Since the two strategists said this, Fei Qian had no opinion, so he set a time, and then said, "...... Should the number of scouts be reduced from time to time? ”

Unexpectedly, Xun Chen and Xu Shu said almost at the same time: "No! ”

Xun Chen smiled at Xu Shu and stretched out his hand to signal.

Xu Shu also arched his hand slightly towards Xun Chen, and then said to Fei Qian: "The prince still needs to order to increase the intensity of the extermination of the Xiliang scouts...... What is too easy to obtain, is generally not cherished......"
