Crop the parchment map and hide the ones you don't use first.

Zhang Yuan opened the door and strode outside.

Now that I have paper, I'm going to have to find someone to make a few copies.

As for whether the wind will be revealed, Zhang Yuan didn't think about it so much.

The Huns have not yet broken the cattle to be able to install spies in Taixue, and the group of ghost slaves of Han Wangxin are already no one and no ghosts, they are just slaves on the grassland, but if they really come back, it is definitely more terrible than death.

At all times and in all places, people hate traitors far more than enemies.

Since he was not afraid of being known by others, in order to show the openness in Zhang Yuan's heart, and more importantly, in order to be lazy, Zhang Yuan chose to ask others to draw a map.

"What is this Taixue Ling?"

After finding King Wuqiu Shou, Zhang Yuan threw the sheepskin scroll in his hand onto his table.

Taixue estimated that except for Zhang Yuan, everyone else had not recovered from the impact of the previous few days.

"Map, you find a few students to copy it on the paper in a one-to-one ratio.

Give me the most elaborate one, and then you can make hundreds of copies of the map, and I'll be of great use. ”

King Wuqiu Shou listened to Zhang Yuan's instructions while spreading out the sheepskin map.

His pupils slowly dilated as the parchment scroll unfolded.

The first thing to come out was the territory of the Han Dynasty, even if the map was marked in detail, it didn't surprise King Wuqiu Shou too much.

To tell the truth, King Wuqiu Shou has not seen many maps, and he doesn't know how bad the drawing level of the Han is.

At present, many places are still inaccessible, such as some steep mountains and dangerous currents, which directly led to the fact that the level of surveying and mapping in Dahan has not been greatly developed.

Of course, it is estimated to be the best in this era, but it is definitely not as good as Zhang Yuan's map.

Zhang Yuan's map does not indicate what the proportion is, otherwise it would be too abrupt to make a comparison of how many or how many are in this era.

When people asked Zhang Yuan what that one was, Zhang Yuan couldn't answer that it was one centimeter.

And there is a gap between the current length distance and later generations.

The parchment map does not have a scale on it, which is also very easy to get, just measure the distance between the two cities, and then compare the actual distance, and the scale will come out naturally.

Zhang Yuan will not do this thing, and in the future, when he divides the map or makes a map of other scales, he can hand it over to the students.

Drawing and drawing is also one of the courses that Zhang Yuan wants to offer in this new discipline.

At the very least, the Han Dynasty has a great demand for this kind of map, and the more detailed the map, the more detailed the army can be.

In these years, it was all group army operations, and it was rare for a single team of a few hundred people to attack, or to disperse the large army and then cooperate with the operation.

There is a small force of Han troops attacking the Xiongnu, and they will not cooperate with other large armies.

For example, this was the case when Huo Qubing led the troops to the expedition.

The commander who led the army did not dare to divide the army easily, and there are too many examples in history of such a dispersed army that led to the defeat of the war.

It has also created a lot of lost generals.

In a strange place, you can't scatter the army, you have to concentrate your forces.

But with detailed maps, and even when the enemy forces aren't even familiar with the place yourself, it's no longer a dream to work together.

The last time the Xiongnu attacked, although the Han army was cooperating, it was still a kind of encirclement warfare, and there was definitely no shadow of any coordinated operation that should exist.

Of course, this is because there is no level yet.

Zhang Yuan wanted to train the tactical abilities of the generals of the army, but he didn't have the qualifications yet.

You can only train people who are familiar with the map for the Han army first, and then see if you can directly intervene in the training of generals, or maybe it is more appropriate to focus on Wei Qing.

"Taixue Ling, this is a map of the desert?"

In the vast prairie, there are not many things that can be recognized.

The original map of the Xiongnu territory of the Han Dynasty was blank, and it was useless for Heqin's team to go to the desert and come back.

Because it won't be long before the tribes of the Xiongnu will migrate.

The only thing the Han knows is the dragon city of the Huns, and further north it is really a blank.

On Zhang Yuan's map, although there are many blanks, many mountains, lakes and rivers are marked.

Although King Wuqiu Shou had not seen many maps, he also knew what was the main reason for the previous defeat against the Huns.

No one was able to catch the Huns on the steppe, but with a map it was different.

"Yes, when I fought against the Huns a few years ago, I met a merchant who secretly traded with the Huns.

I promised him a great deal of profit, telling him that as long as he could draw a map of the desert, he would be sure to be rich and prosperous forever.

In addition, I also sent someone to collect our big man's own map, so that it was stitched together to become what you see now. ”

King Wuqiu Shouwang stood up, and then finished his upper body and bowed to Zhang Yuan, and his upper body and lower body directly became ninety degrees.

This kind of etiquette is already the limit of being able to express respect in the era when knees can only kneel and lick and kneel to their parents.

"Xia Guan is fortunate to do things with Taixue Ling in this life.

What is Dr. Hanqing, now in the eyes of the lower officials, you are Dr. Hanqing! ”

King Wuqiu Shou used an accent when he read the last few words, and it was only at this time that Zhang Yuan could be regarded as convinced.

In this country, it is not only the surname Liu who regards the Huns as a shame, from the emperor to a low-level slave, the first reaction when seeing the Huns is definitely to look to see if there are any weapons on the side.

It is sad and lamentable, the best way to stimulate the blood and cohesion of a nation is to use another nation to stimulate it.

Rather die standing than live on your knees, this is China's unyielding spirit for thousands of years.

No matter how it is tampered with and propagated by future generations.

In the Han Dynasty, the Huns had to die.

In the Northern and Southern Dynasties, Xianbei and other alien races were the natural enemies of the Han people, blood feuds!

In the Song Dynasty, foreign countries such as Western Xia and Liao were also the natural enemies of the Han people, even if some people knelt down, what was the result? The wolf's ambition is well known to the world, how can it be justified to feed the wolf with his body?

Later, the Mongols and even the Jurchens and other foreign races, how could the slaughter of the Han people be less?

In a certain era, those who fought for the country were heroes, national heroes, national heroes, and heroes of the people.

It is absolutely impossible for some people to dilute this imprint.

Zhang Yuan was a big man two thousand years ago, and when he looked at King Wuqiu Shou with his eyes, he could clearly feel the pride engraved in each other's bones.

In the rolling waves of history, it is indisputable that the Han people are conquerors, and this world will not be wiped out by others only if it never stops conquering.

Peace is for some naïve people, and only by letting one's fist get bigger and tighter can the nation continue to be strong and strong, and only then can we ensure that civilization is not cut off!
