Chu Yuhan was also surprised. With these two things, gunpowder could be made naturally. She said happily, "Nangong Jia, it's hard for you. Now that you have found these two things, go and buy them both. But now I have to give you an important task: where to produce what, when to produce it, where to urgently need what, as long as you know it yourself, give it to me, write it on parchment, and give it to me. "

Then Chu Yuhan looked at Zu Yuanfei again: "brother zushi, you have passed through so many places in yuncanmeng mainland, and you should know something about the products of different places. Please also list the local products you know on a piece of parchment and give them to me. You also have a task, that is, whether you can draw a map for me, that is, where is the cloud Kingdom, where is the moon Kingdom, and where is the Xianyuan mountain in yuncanmeng continent... I know you can't draw a very detailed map, but can you draw a rough map? "

Zu Yuanfei thought for a moment and said, "younger martial sister Yuhan, I can help you to complete the first task, but the second task will make me embarrassed."

Chu Yuhan understood and said, "well, I know, so I just want you to draw a rough map." Speaking of this, she looked at yunchenyi: "yunchenyi, how much do you know about the mountains and rivers in yuncanmeng?"

Yun Chen shook his head in shame: "Chu Zhuang Shi, I'm really ashamed. I just went to some places with you. I don't know much about others."

Because Nangong Jia is on the side, Yunchen's meaning comes from the common name in front of ordinary people, calling Chu Yuhan a strong man of Chu.

Chu Yuhan sighed helplessly and said, "forget it, it's not right for you. Now go and get a piece of parchment and a pen. Or you say, I'll draw it myself. "

Yunchenyi opens the door and goes out.

Zu Yuanfei looked at Chu Yuhan and asked, "Chu Zhuang Shi, do you know the mountains and rivers of yuncanmeng mainland? You have to actually walk, just look at the picture, that's not good. "

Chu Yuhan said: "I just need to know something about it, but it's not for marching and fighting."

Zu Yuanfei asked curiously, "what do you think of Chu Zhuang Shi? Listen to your tone, it should be related to goods trading, right

Chu Yuhan nodded: "well, there are ideas about this, but now we have to understand it."

After a while, Yun Chenyi brought a large piece of parchment, a brush and an inkstone and ink.

Looking at the inkstone and ink, Chu Yuhan frowned. This age is really too backward! She sighed: "cloud dust meaning, you just go to pick up a few charcoal, this brush, I'm not used to it."

Cloud dust meaning then goes out again to pick up a few black charcoal.

Chu Yuhan spread the parchment on the table, picked up a charcoal and lit it on the top: "this is the north. Left West right east... So this is the West. " With that, she pointed on the left, and then marked the four directions of southeast, northwest and North.

After marking the direction, Chu Yuhan looked at Zu Yuanfei: "now you say, what country is the north."

Zu Yuanfei thought for a moment and said, "it's the plateau people and the desert people. The plateau people are in the west, and the desert people are in the East."

Chu Yuhan looks at Nangong Jia, and Nangong Jia nods.

Chu Yuhan drew two big circles on it, in which he wrote the plateau nationality and desert nationality.

Seeing these words, Yun Chenyi, Zu Yuanfei and Nangong Jia all opened their eyes. They didn't know these words. At first, when Chu Yuhan marked the four directions of southeast, northwest and North, they thought that Chu Yuhan used a special mark. Now they know that it's also a character.

Seeing the puzzled expression of the three people, Chu Yuhan realized that he had written modern characters, but they didn't know each other. "Don't just look," she said. Then which country do the plateau people and desert people belong to? "

Zu Yuanfei thought again and said, "the west is a magic forest. Next to the highland people and the magic forest is the cloud country, which is also connected with the desert people. Cloud used to be a cold country. "

According to Zu Yuanfei, Chu Yuhan drew several big circles on the parchment to indicate magic forest, cloud country and cold country, and also wrote words.

Next to the magic forest are the kingdom of Jing and the kingdom of Lin, which Chu Yuhan knew, so he drew the kingdom of Jing and the kingdom of Lin.

Nangong Jia said, "it's the Han state that goes down from Jing state, and the Han state or the Lin state."

Chu Yuhan painted Han again.

Nangong Jia also said, "to the east of the Han state is the state of the moon. In addition to the border with the state of Lin and the state of Han, the state of the moon also borders with the state of Yun in the north. However, the border line is not long, only ten miles long."

Chu Yuhan drew the circle of the moon Kingdom, and then asked: "in this way, the moon Kingdom and the cold Kingdom also border?"Zu Yuanfei nodded: "yes. In the East, it is the state of Qiong. "

Chu Yuhan then drew the state of Qiong, and then looked at the three people: "now you can see if this picture can roughly depict the present situation of Yuncan dream land."

Three people left look right look, just feel a bit awkward, but can not say why.

Chu Yuhan knew what they meant, so he said: "this map can only show the general meaning. If you want to draw an accurate map, you have to check it on the spot. Of course, it's better to have satellite photos. Unfortunately... "

Three people don't understand what Chu Yuhan said satellite photography is, staring at her.

Chu Yuhan ignored them, but just looked at the picture and pondered. For a long time, she said: "from this picture, we still need to establish a stronghold in a place, that is, the place where the cloud Kingdom meets the moon kingdom. If we establish a stronghold there like the trading city on the western plateau, the horses needed by the moon Kingdom and Qiong kingdom can be traded directly from there. There's no need to take the magic forest road, so it's much closer. Yunchenyi, which jurisdiction does it belong to? Is it under the jurisdiction of Quguan city as mentioned by General Gao? "

Cloud dust meaning nods: "yes."

"Why are there only 20000 troops there? There are several countries bordering on it? " Chu Yuhan looked at his sketch again. "You see, it's the boundary between the cloud Kingdom and the forest kingdom, the moon Kingdom and the cold kingdom."

Yun Chenyi said with a smile: "it is because of the border with many countries that there are fewer wars. A few countries dare not send out troops easily, but dare to defend themselves in their own countries."

Chu rain cold think about it, also feel some truth. As soon as the troops go out, no matter which country you invade, you worry that other countries will send troops to attack you.

However, such a situation is even better for trade. After Chu Yuhan learned about this situation, he was more determined to build a fixed trading place there
