In the early morning, the sky showed a glimmer of dawn, Zhao Hao got up from the warm animal skin quilt as if he had set an alarm clock, washed up quickly, and then came to the tent dedicated to storing the internal organs of foreign beasts, cooked belly tablet soup, heated a pot of mare's milk wine, and ate a beautiful meal.

At this time, the sky was already bright, and the women had already gotten up, and after saying goodbye to the women directly, he summoned the white dragon and went straight to the grassland outside the valley.

In order to make it easier for the cavalry of each battalion to report, he had already set up a big tent on the grassland outside the valley, and every morning, he would run to the big tent on horseback and sit there as if he were going to work, waiting for the cavalry of each battalion to come and report the latest news, and record it in detail.

At this time, the cavalry of each battalion has been fully deployed, and twenty-four hundred-person cavalry teams are constantly searching in the wild jungle, and almost every day several teams of cavalry come back to report, and find a certain small tribe somewhere, and Zhao Hao recorded more and more bamboo slips of various tribes, for this reason, he even made a bookshelf to store bamboo slips.

Early that morning, he came to the big tent, and habitually picked up the bamboo slips on the bookshelf and flipped through them.

There are more tribes in the wild jungle than he imagined, especially in the eastern part of the grassland, the tribes are even more dense, and it has only been half a month, and the eight cavalry battalions and twenty-four cavalry squads have been able to search the wild jungle within five days' distance, and nearly twenty small tribes have been found.

It is a good thing that there are many small tribes, because the more small tribes there are, the more people they have, and what he needs now is the population, but it is also a trouble to have too many small tribes, because not every tribe will willingly join the Ministry of Salt, and when the time comes, he will have to arrange some people and use some means to subdue these tribes.

At this time, he has used bamboo slips to write down all the basic information of the tribe that he has searched out these days, and it stands to reason that he should not be chaotic when he receives it in the future, but he always feels that this is not very intuitive, after all, every time he thinks of a tribe, he has to turn over the bamboo slips, dozens of tribes, he has to turn over dozens of bamboo slips, and it is too troublesome.

So, what to do?

This is actually very simple, draw a map, mark the location and basic information of all tribes on it, and when the time comes, if you voluntarily join the salt department, draw a circle, and if you don't want to join the salt department, draw a cross, at a glance.

Problem, this bamboo slip on the map, really not easy to draw, because there is a gap between the bamboo slips, the map must be drawn intermittently, it looks uncomfortable, and, dozens of tribes to mark out, then at least have to make a one-meter square bamboo slip, that thing, not to mention that it is inconvenient to look at, even if it is inconvenient to carry.

How to solve this problem?

Zhao Hao sat there and thought about it for a long time, and finally thought of a good thing.

This thing is sheepskin!

After the sheepskin is dried, most of it is white, and the inner surface is still very flat, so it is the same as thicker paper, which is convenient to draw a map, and it is also convenient to roll up the sheepskin with the body, as long as it is rolled up and tied to the body, it is not in the way at all.

The sheepskin was also very easy to find, so he called in the guards on duty outside, and gave a few casual explanations, and soon they found several sun-dried sheepskins from the nearby clansmen.

The sheep at this time are much stronger than the sheep of later generations, and a large sheepskin is almost one meter and a half square, which is more than enough for drawing maps.

However, after the sheepskin was found, he encountered a new problem, that is, he did not have such a large table in his tent to put such a large sheepskin. Fastest update Desktop::/

If the sheepskin is placed on the ground, it is definitely impossible to draw a map, because it is not easy to draw the line with a brush, and if the sheepskin is placed on the uneven ground, it is strange that the line drawn is not crooked, so it is necessary to put the sheepskin on the table flat.

At this time, there are many clansmen in the Salt Department and the Black Stone Department who will make tables, but the tables they make are generally only one meter square at the largest, because it is useless to make them bigger, and no one wants them.

In desperation, he had no choice but to ask the guards to hurry up and go to Salt Stone City, find the best carpenter, and customize a two-meter square table.

Of course, at this time, there are no standard rulers in the salt department and the black stone department, how long and wide is two meters square, and basically no one understands when he says it, he can only tell people to make a table that is longer and wider than a person.

Fortunately, the people of the Salt Department and the Black Stone tribe were very diligent at this time, as long as they could afford enough meat, they were quite fast to work, and in less than a day, the large table he customized was delivered to the big tent.

He spread a large sheepskin on the table, sharpened some ink, and was ready to start drawing the map.

He can still draw simple military maps, basically determine the size ratio first, then find a reference point, and then draw it around according to the scale.

This reference point is easy to find, Salt Stone City is a very good reference point, but this size ratio is a little difficult to determine, because at this time he does not have the tools to measure the distance in his hand, what is in the unit of miles or kilometers is definitely not good, he can't measure such an accurate distance at all.

In the end, he can only use the speed of the horse and the speed of the person on foot as the basic unit, the horse gallops for a day, even if it is about 500 miles, and the person walks for a day, even if it is about 50 miles, with this as the basic unit, there will definitely be some deviations, but the approximate distance should not be much worse.

He just drew it according to what he had in mind.

The middle of the map is Salt Stone City, the left side of the map is the continuous snow mountain, between the salt stone city and the snow mountain is roughly divided into ten equal parts, each point is roughly a day's horse, that is, about five hundred miles, and then in this ratio, mark the big river on the eastern edge of the grassland and the wild jungle on the northern edge of the grassland, and a rough outline comes out.

Then, there are some familiar places, such as the old land of the salt department and the old land of the northern mountain department, for example, the lake found in the middle of the grassland, and for example, the bamboo forest in the valley where he now lives.

For example, starting from the grassland north of Salt Stone City, beating horses westward for three and a half days, there is a small river, along the small river to the south, walking in the wild jungle for about a day, there is a tribe with a population of about two hundred, that is, the position of the left third and a half of Salt Stone City, and then one-tenth to the south, draw a small dot, and then write about two hundred fine characters.

He drew carefully for a few days, and a detailed parchment map finally took shape, on which not only the information of the small tribes that had joined the Ministry of Salt such as the old land of the Beishan Department and the old land of the Qinghe Department was also the information of all the small tribes that had been discovered but did not join the Ministry of Salt in the past two years, and their approximate location and scale were clear at a glance.

With this map, a lot of things are much more convenient.

For example, if he wants to count the total population that has been discovered, he doesn't have to open the bamboo slips and add them one by one, just add them to the numbers on the map.
