At night, Zhang Fei, who had not been seen for a long time, came back.

Zhang Fei was dusty and dusty, and his face was gray.

During the meal, Li Mengxi showed the eggs to Liu, Guan, and Zhang, as if asking for credit, saying that they were laid by raised chickens and ducks.

A small egg, although it is a small thing, is not bought or robbed, but laid by the chicken itself, which is of great significance.

Liu Guanzhang passed the eggs around and admired them.

Finally, Liu Bei wanted to give the egg to Li Mengxi again, "Xi'er, the eggs can be boiled, and your two brothers can eat them."

"I ate an egg, egg, egg." Xiao Zhuan said in a sweet voice.

"Haha!" Li Mengxi laughed immediately, "We have eaten it."

After saying that, Li Mengxi looked at Zhang Fei, who had not bothered to wash his face, and looked like a native, and smiled, "The third general has a dusty life, and his hard work has made great achievements. If not, just give it to the third general."

Liu Bei smiled and handed the egg to Zhang Fei, "Since Xi'er said so, here it is, third brother, take it."

Zhang Fei didn't show any pretense, he took the egg, popped the shell open with his fingers, then raised his head and drank the egg raw.

Zhang Fei is worthy of Zhang Fei, he has a bold spirit even if he drinks eggs.

After drinking the eggs, Zhang Fei threw the shells into the fire.

Turning around, Zhang Fei asked, "Xiao Meng, you sent me a message saying that you have something important to discuss with me, and you have to ask me, Lao Zhang, to come back. Tell me, what is it?"

Calling Zhang Fei back was a matter for the scouts. He wanted the scouts to see how to provide intelligence support to the caravan to improve procurement efficiency.

"That's right, Third General." Li Mengxi thought for a moment and said, "Three Generals lead the scouts to expand dozens or hundreds of miles. I wonder how many villages the scouts encounter every day when they are exploring everywhere?"

Zhang Fei scratched his beard that was scurrying like a steel needle with his big hand, and said with a thoughtful look on his face, "There are encounters in the village every day."

Li Mengxi nodded. With the number of scouts and the wide range of exploration, the number of villages they encountered must far exceed the two mere caravans.

"When our army's ranger caravans leave the army to purchase goods every day, they are tired of looking for villages everywhere.

This is why we are looking for the third general, to see how the scouts will inform the caravans of the villages they encounter, so as to make the purchase more convenient."

That's why.

Zhang Fei's eyes widened and he glanced at Li Mengxi.

Subconsciously, Zhang Fei wanted to say that after the scouts found the village, they would return directly and inform the caravan.

But when you think about it, the scout has a heavy responsibility. In order to guide the traveling caravan, the scout has to return frequently, which is not worth the loss.

After frowning and thinking for a long time, Zhang Fei said, "Every few days, when my scout team returns to the army to replenish rations, how about informing the caravan of the location of each village?"

Li Mengxi was still thinking about the feasibility of Zhang Fei's method, and Guan Yu was the first to object.

"Third brother, I'm afraid this is inappropriate." Guan Yu objected, "There are thousands of intersections on the roads and byways. How can we explain clearly by just talking? How can the traveling caravan know where to go?"

After listening to Guan Yu's words, Li Mengxi realized the problem belatedly.

The problem is that the scout team is not very good and cannot draw accurate maps.

If the scout can draw a very accurate map, then every few days, he will send back a small set of maps, and then the caravan will take the map and follow the map to find the right one.

This is an ideal situation. The scouts must have enough paper and be able to draw pictures, and the rest of the army must also be able to read pictures.

Such a high-quality army, the rebel army currently cannot reach this level.

Now when scouts give directions, the way of communication is not to rely on talking, but to lead the way directly.

For example, when setting up camp every evening, a scout would lead the fishing team to fish where there is water. If the scout did not lead him there and just rely on his words, it would be almost impossible for the fishing team to get through with only a few words of information.

The intricate road to find the destination.

Therefore, Zhang Fei's method does not work.

At this time, Li Mengxi thought of a useful method.

"I have a way so that the scouts don't have to come back.

If you encounter a village, the scouts can plant a flag beside the road as a sign.

When my army marched along the main road, the caravan saw a flag at the intersection, and knew that there was a village here, so it took out the flag and went to look for it. Isn't this convenient? "

As soon as Li Mengxi's method was revealed, Liu, Guan, and Zhang's eyes lit up.

There is no doubt that this method is feasible.

Liu Bei pondered for a moment, and suddenly remembered the shortcomings of this, "Hey... Xi'er, it's okay for the scouts to plant flags at the intersection. But if the flags are planted in front of the scouts, my army will arrive in two days. In this wilderness, the country people

When you pass by and see the flag, why don’t you take it away?”

When Liu Bei said this, Li Mengxi was amused.

But no, the scouts were out of touch with the army, and the flag was planted there alone. When the sheepherder saw it, he conveniently took the flag away.

This is inappropriate,

On the other hand, Zhang Fei made a supplement to Li Mengxi's proposal.

"You can leave stones as a mark," Zhang Fei said, "at the intersection, put a pile of stones as a mark, or plant a branch as a mark.

I don’t expect anyone to take the branches and rocks, right?”

Li Mengxi added, "It's good to leave a stone as a memory.

It's just that the army is marching in a hurry, the piles of rocks are small, and the carriages are whizzing by, making it difficult to see.

Therefore, it is better to leave the flag at the intersection, and at the same time, leave a pile of rocks and plant branches as a reminder."

Li Mengxi's triple insurance method was approved by Liu Bei, Guan Yu, and Zhang Fei.

At this point in the discussion, things seem to be perfect.

However, Li Mengxi simulated the path-finding process of the caravan in his mind.

The traveling caravans no longer left the group and wandered around aimlessly, but instead marched along with the army.

As we walked, we saw a stone signal left by a scout on the roadside two days ago at the intersection.

So, the caravan left that intersection and looked forward.

After walking for a while, I was dumbfounded when I saw a crossroads ahead.

Where does this go?

At this point in the simulation, something went wrong.

Li Mengxi told Liu, Guan, and Zhang about the problem, and they all frowned.

In terms of life experience, Liu Bei and the others have more experience than Li Mengxi.

Liu Bei folded a thin stick, frowned and tried drawing on the ground a few times. When he thought of something, Liu Bei's brows relaxed.

"There are two ways.

First, the scouts used stones as marks and left traces everywhere. When they passed an intersection, they left a pile of stones.

The caravan can just follow the pile of rocks to find its way.

Second, leave a sketch on the ground at the intersection of the main road. Draw a line, turn once at the intersection, then add a cross. Turn left at the intersection, cross it on the left, turn right at the intersection, draw the right cross, and mark it like this?" Liu Bei said.

He raised his head and asked.

Li Mengxi thought for a while, and the method Liu Bei said should be like this. Draw a map with simple line segments. If there is no need to turn at the intersection, draw a short line mark at the intersection. If you need to turn from the intersection, draw a long line mark.

That is, on a straight line, looking from bottom to top, you can see that there are two short lines on the left side of the straight line and three short lines on the right side. This means that if you go straight forward, you will encounter two intersections on the left and three intersections on the right.

, no need to turn.

Then go up, there is a long line segment on the right side of the line segment, this sign, when you encounter the fourth intersection on the right, turn right.

In this way, the direction can be guided more accurately.

Excellent.

Li Mengxi scratched his head and blurted out, "Where can I find the stone?"

Liu Bei, Guan Yu, Zhang Fei were all stunned.

What Li Mengxi said is that since stones are needed to pile up stones as a mark, then the scouts are not allowed to look for stones everywhere?

How many stones are placed at an intersection? How many stones are placed at an intersection? The scout has to stop looking for stones?

Li Mengxi was worried that it would be difficult to find stones here, and the scouts would waste a lot of time looking for them.

After understanding what Li Mengxi was worried about, Liu Bei smiled and said, "If there are no stones, you can just make a pile of earth."

Liu Bei solved the problem with a simple word.

Li Mengxi thought about it, yes, if there are no stones, just poke two pieces of hard soil with a knife and pile them up at any intersection, which can also serve as a guide.
