He took it out and hung the landscape map on the stone wall of the stone chamber, and observed it by the light of the burning grease torches.

The last time he looked at it, he had ruled out the possibility that this landscape map was a visualization map, and guessed that since it could be collected by the Eastern Demon Hunter, it was definitely not a simple landscape painting, so he estimated what secrets this picture hid, but it was difficult to find.

Last time, he watched it for a long time, and all kinds of methods were exhausted, but he didn't see the fame.

This landscape map is made of metal scrolls and white paper, and there is no peculiarity in the materials, they are all very ordinary materials, so the landscape map is not a magic weapon, and the secret must be in the picture.

Wang Lun observed the picture again.

On the paper, there is a majestic mountain and a meandering river flowing below the mountain. To say that such mountains and rivers are too common, it is not enough to determine the uniqueness of this place by relying on mountains and rivers, Wang Lun is sure that even if you look outside Laiyang City, you can find similar places.

Obviously, the landscape is not pointing somewhere.

Wang Lun was thinking, what is hidden in this painting, the lines of the mountains are very simple, and the lines of the river are even simpler.

It may be that he has been studying the five drawings for so many days before, thinking about the lines on the map, but at this moment, after Wang Lun stared at the landscape map for a while, the ghost made a miracle, and also split the mountain, split the river, and looked at the outline lines along the outline.

The outline of the mountain resembles a fan. This fan-shaped mountain is very common. A contour is an arc with two oblique straight lines.

The shape of the river is connected by several "S's". The contour line can be seen as a number of positive and reverse "S's".

"In such a place, there are indeed a lot of them, many rivers are nine bends and eighteen bends, and many mountains are like unfolding fans. ”

"The outline lines of the mountains and rivers are simple and not complicated at all. On the contrary, the lines of the water in the river and the trees on the mountains are very complex, many times more complex than the lines on the five pictures. ”

Wang Lun felt that he was a little nervous, and he analyzed the lines as much as he could, and the lines were matched.

Suddenly, Wang Lun stared at the picture and found something interesting.

It is to remove the densely painted and realistic trees on the mountain, or in other words, to leave only one tree, and then retain the outline of the mountain, with this simple tree and a simple fan-shaped outline, it should also be able to make people see, this is a mountain in the painting!

In the same way, the meandering river with its sparkling water streaks and the reeds drifting in the wind on its banks, but removing these reeds, removing the grass and shrubs on the banks, removing most of the water streaks, and retaining only the simple outline of the river and a few ripples, it is also possible to see at a glance that this is a river with water flowing through.

Wang Lun suddenly realized that if this landscape painting wants to be beautiful and beautiful, then it should be painted like this on the picture, but if you just want people to understand that the painting is a mountain and a river, then the simplest strokes and the two simplest outlines are enough.

He looked at the five drawings and saw intertwined lines, although he knew that these lines showed a map, but there were too many lines, obscuring the original appearance of the map, and most of the lines should be useless and meaningless.

Just like if he wants to draw the simplest landscape map, then those complicated lines can be completely removed, and the simple outline of the landscape can be sketched with a few strokes.

"If I follow this line of thinking, I think that the real map is covered by too many useless lines, and these useless and complex lines need to be removed. ”

"Anyway, it's just trying, and it's okay to try it along this line, but how do you tell which lines are useful and which aren't?"

Wang Lun is not whimsical, in fact, in order to uncover the secret of the map on the black iron sheet, he has thought of all kinds of methods, including many strange methods, and the method he thinks of now also belongs to the category of wonderful, but it may not be impossible to try.

After all, all kinds of methods have been exhausted, and it is nothing to use one more strange method.

"Like this landscape map, if the mountains and rivers are to be presented simply, it is also necessary to remove too many useless lines, just this one

It's easy to remove, anyway, as long as you keep the contour lines. ”

But these five pictures have no outlines, and useless lines can't be distinguished. ”

Wang Lun didn't know which lines to keep and which useless lines to remove.

"It seems that this strange method can't even be tried. Wang Lun smiled bitterly.

The method that came out was unreliable, so Wang Lun didn't continue to drill the tip of the horns, put away the landscape map, drank some mountain spring water collected from the mountains and stored in a bottle, Wang Lun continued to meditate and cultivate.

The effect of the Spirit Gathering Array absorbing the surrounding spiritual energy is okay, but there is very little spiritual energy around, staying in the Spirit Gathering Array, Wang Lun didn't feel that the spiritual energy was sufficient, and it was not comparable to directly using medium-grade spirit stones to cultivate, but now with this condition, Wang Lun was calm and quickly entered the cultivation state.

Wang Lun kept refining the mana in his body, and the mana traveled in the meridians between the hundreds of bones of his limbs, running week after week, and he didn't know how long it had been, when Wang Lun opened his eyes again, he already felt a little tired.

His continuous mana refining has never rested in between, and his mind is immersed in it, and it is impossible for it to last forever.

In fact, he had been refining his mana for three days and three nights this time, and it was normal for him to be a little tired.

The monk's normal retreat practice, including meditation, sleeping, breathing in aura, etc., is not always refining mana, so that he can retreat for several years or even more than ten years.

felt a little tired, Wang Lun didn't insist on working hard, and fell asleep.

Anyway, I only need to sleep for three or four hours, and I wake up full of energy.

Wang Lun soon fell asleep, and then began to dream rarely.

I used to dream occasionally, and the most common scene in my dream was my life with my parents, or with Chen Ruolan in Yinshan Village, such as walking with Chen Ruolan, such as sitting on a low stool in the yard with my mother Qin Huirou to pick vegetables, such as following my father Wang Dafang to bring the family's hunting dogs and little liger beasts into the mountains to hunt and so on.

I also dream today, but what Wang Lun dreamed of was very different from the previous ones.

First, there is a diagram full of intertwined lines, and then these lines fly out one after another as if they were alive, and as if planned, similar lines will fly out in batches, and then it will be the turn of the next set of similar lines.

Soon, all the lines on this picture flew away, and there was nothing left.

Then, there was the landscape painting, and the picture was the one in the painting, and then the trees on the mountain began to fly away, the grass began to fly away, and the reeds on both sides of the river bank began to fly away......

However, before the things on the painting were all gone, Wang Lun woke up.

After waking up, Wang Lun remembered the general process of this dream, and couldn't help patting his head, the secret saying must be racking his brains to study the five pictures these days, leaving sequelae, and he dreamed of this.

But immediately after, Wang Lun became interested in the lines that flew away in his dream.

What he remembers is that the lines fly away in groups, and in the same group, the lines are similar, for example, the lines that look like "7" will form a group, the straighter lines will form a group, and so on.

This is clearly to split the lines in the diagram and classify them.

Wang Lun thought about this dream, and a thought involuntarily popped up: Could it be that a hint was given in the dream?

Anyway, other methods that were thought to be impossible before can now be carried out, and Wang Lun feels that it is not impossible to split the lines.

You can see what can appear after the lines are classified.

Wang Lun then began the operation in the stone chamber.

He first used his mana to make a white curtain, and then used his mana to copy the first picture on the white screen, which was black and very obvious on the white screen.

After that, he used his mana copying ability to copy the same white curtain, as many as fifteen pieces.

On each white screen, there is the first picture.

Next, he chooses a group of straighter lines and takes all the non-conforming lines on the first white screen

The lines are removed, anyway, the lines are all mana, and it only takes one idea for the selected lines to disappear.

So soon, the first white screen was full of relatively straight lines.

These 20 or so lines are almost scattered, and some of them are intertwined, because there are many fewer lines, and the diagram looks very simple, but it is no longer obvious that this represents a map.

Wang Lun didn't stop to think about the significance of this picture on the white screen, after all, the work had just begun, and there were other types of lines waiting to be processed behind it.

Wang Lun's second set of lines is a "V" shaped line. There are obviously a lot fewer of these lines, only seven or eight.

The third set of lines is in the shape of "7", or lines like "∟".

After that, Wang Lun chose lines like "∫", lines like "⌒", and lines like "S......

Anyway, after comparison, Wang Lun found a total of thirteen lines of different shapes, so thirteen groups of white curtains appeared.

After analyzing, Wang Lun found that there are the most straight lines, followed by the "S" line and the "⌒" line, and the number of other lines can be said to be obviously not as many as these three.

It's just that the lines have been split, and the thirteen white curtains in front of him have also been stared at, and Wang Lun didn't see the clues.

The real map on the black iron plate certainly cannot be composed of only one line, maybe there will be thirteen lines, maybe only some of them.

But Wang Lun couldn't judge.

Seeing that he couldn't judge, Wang Lun didn't have a fantasy, and kept the thirteen white curtains unchanged, Wang Lun took out the second picture, concocted it in the same way, copied this picture on the white screen, and then copied more than a dozen copies.

Next, Wang Lun split the lines as usual.

After dismantling it, Wang Lun found that this second picture was composed of only twelve kinds of lines, and one was missing. Then the inventory found that there were still the most straight lines, followed by the "S" line and "⌒", anyway, the top three did not change, and the ranking only changed when it came to other kinds of lines in the back.

Wang Lun has a total of five pictures, and he split the remaining three pictures in one go.

After summarizing, Wang Lun found that the lines composed of the five drawings were thirteen, twelve, twelve, fourteen, and eleven.

But without exception, in terms of quantity, the first is the straight line, the second is the "S" line, and the third is the "⌒" line.

From the fourth to the last, the ranking of the five charts has changed and is no longer fixed.

If there is any pattern found, Wang Lun found that the top three remain unchanged.

You must know that the five black iron pieces are on a certain item, and a single piece is incomplete, but on any single piece, the first three lines are the same, which can fully explain that on the complete map, there should be the most of these three lines.

Wang Lun was surprised that whether it was a straight line, an "S" line, or a "⌒" line, it was precisely the line used to form the simplest mountain and river outlines on the landscape map.

The outline of the mountain, which is a straight line with "⌒", constitutes a fan-shaped peak.

The outline of the river is the "S" line.

Is this a coincidence? Or is there a connection between the two?

"There is a piece of black iron that was found in the cave of the Eastern Demons. ”

"The landscape map is also in the cave of the Eastern Demon Queen, and it is placed together with the black iron plate. ”

"Landscape drawings are not magic weapons, scrolls and paper are very ordinary, mountains and water are also painted, if you want to say that there is any secret of landscape drawing, the secret is in the painting. ”

Wang Lun muttered to himself, and after finishing speaking, he found that he ...... There's really no way to force a connection between the two.

But whatever, I've used the weird method to this point, so I'll keep going.

The next step is to keep only those three lines for each map, and see if the three lines can outline the appearance of mountains and rivers, and the three lines can also outline the appearance of the map.
