After a pause, Lu Jiuye continued: "however, it's not difficult to recover the human skin, because the human skin can be extended as long as it meets water. In that case, we can see the above content. It's just that the human skin has been in the world for a long time. After it recovers, it will be directly broken and disappear next time."

"That is to say, we need to record the content on it this time, otherwise, the content on the skin will disappear forever?" Zhang Fan frowned and asked Lu Jiuye.

"Not bad." Lu Jiuye nodded slightly and continued to say to Zhang Fan, "so what we need to do now is to find some water so that we can see the above contents."

Yan Fei frowned and thought for a moment, and asked Lu Jiuye, "but in the desert, there is a desolation everywhere, and there is no water. Even if there is water, it is in a certain space boundary. In this way, don't we have to go back for a long distance?"

"It's easy."

With a smile, Gao E took out a wine bowl from his storage ring, filled it with wine, and said to Zhang Fan, "we can use wine to unfold human skin, so that we can see the things on it."

Zhang Fan nodded, looked for a relatively flat stone, put the human skin on it carefully, and spread it as far as possible.

Gao E is to use the wine bowl in the top, try to drench some evenly, so as not to miss.

At this time, the human skin has been slowly unfolded, and some of the above contents have begun to appear gradually.

Zhang Fan quickly took out the paper and pen and began to record the above things, trying to restore all the above things.

People are very curious to see the information in front of them, and they don't know what it is.

"What is this? Is it a symbol left by ancient people? In that case, we can't understand it at all. " Gao E frowned, hugged his shoulder and said with his head tilted.

Dao Lang also carefully analyzed the above things, thought about it and said: "I think it should be some words that we can't understand. In that case, we can only take this thing back and ask my grandfather, maybe he will know what is recorded above."

Yan Fei tilted his head for a while and asked Lu Jiuye: "Jiuye, what do you think is on it? How can I not understand it? Or does this man's skin still not stretch out? "

Lu Jiuye nodded slightly and said, "wait a minute. This person's skin roll takes a long time. We need to wait patiently until it is fully unfolded before we can see what is recorded on it."

With the surrounding wine more and more thick, human skin roll in the wine has also been expanded to the limit, slightly showing some signs of cracking.

At this moment, Zhang Fan began to quickly record the contents of the human skin scroll, trying not to miss any details.

Lu Jiuye carefully analyzed it and said to the four: "in my opinion, what is recorded on it should be a map. However, I don't seem to have seen such a continent. Maybe it's a map in the desert hillock. You see, the picture over there should be mountains, and the road winding up in the middle should be a road."

They followed the interpretation of the ninth master and looked at it carefully.

Looking at the whole picture, we can see the outline of some mountains and the roads around them. But on the far left is a blackened area. I don't know what it is. But in this area, there is a special mark, which seems to tell people what exists in this place.

"If there are mountains and roads on the right, what is the black area on the left? There's no written explanation on this picture. It's very simple. I can't understand it at all. " Gao E frowned and said, shaking his head slightly.

Dao Lang nodded and said: "yes, according to the above records, we can only guess vaguely where is the mountain and where is the road. That black area is likely to be unknown, so it will be marked as black."

Lu Jiuye shook his head slightly and retorted to Dao Lang: "it's impossible. If there is an unknown area over there, why is there a sign? So, I guess the black area over there should not be an unknown area. "

"What is this black area? It seems very mysterious. " Yan Fei frowned and said thoughtfully.

At this time, the human skin roll has begun to appear cracks, the above content, has also begun to become blurred.

Zhang Fan had recorded all the things on the man's skin roll with the paper and notes in his hand. After a brief look, he said to the people, "if I am not wrong, the black area should be the ocean."

"The ocean?"

In their hearts, they were puzzled and looked at Zhang Fan. They didn't understand Zhang Fan's meaning. Even if it was really the ocean, they also needed a certain basis. Otherwise, how could they determine which area was the ocean?"I don't quite understand what you mean. Why do you say this area is an ocean? What is the basis? " Lu Jiuye also had some doubts in his heart. He asked Zhang Fan on one side, and others wanted to hear Zhang Fan's answer.

Zhang Fan explained with a smile: "in fact, the reason is very simple. Look at the direction of these mountains."

With that, Zhang Fan pointed to the directions of some mountains in the picture, motioned people to take a closer look, and continued to explain to them: "the directions of these mountains can extend far away, but when it comes to this black area, it produces a self similar shape. It can be seen that this area should be a coastline, and where there is a coastline, it must be the ocean, so The black area should be the sea

After listening to Zhang Fan's explanation, people suddenly realize that Lu Jiuye, who has a lot of knowledge, has a deep admiration for Zhang Fan. He can't help but praise Zhang Fan's observation in his heart. He is really insightful and meticulous.

Others don't know, but Lu Jiuye is very clear. For the coastline, there can be a self similar shape with the surrounding mountains, roads, rivers and other areas along the coastline, which is also a law in the coastline.

For nature, there are many such situations in the world, such as snowflakes, which form a variety of self similar forms, and finally form the form of snowflakes. If you don't have this knowledge, you can't distinguish it.
