I saw that under the miner's lamp in Dashan's hand, the seven Buddha pictures on the roof produced the effect of the morning sun shining and the daylight flowing, and this effect, under the movement of Dashan and the miner's lamp in his hand, the painting style in the seven Buddha pictures was also producing some subtle changes.

These changes may seem subtle and not very obvious, but once the footsteps of the mountain and the size of the horizontal movement exceed a certain distance, the changes in the picture become two completely different pictures from the style of painting at the first point before.

For example, when the mountain is under the east window, the picture shows seven plain-clothed monks, facing the golden yellow sand city, laughing and talking about the wind, it seems that these seven people, just like tourists on the scenic spot, are talking and discussing something in a happy atmosphere.

But when Dashan walked to the window directly south of this picture with a miner's lamp, the expressions of the seven monks on the picture changed from joy just now to serious staring at each other.

However, when the mountain lamp came to the south wall of the treasure hall, near the last window on the west side, the seven Buddha pictures on the roof changed again.

At this time, the seven plain-clothed monks of the Seven Buddha Diagrams, they no longer looked at each other happily and solemnly, but looked at their companions in a terrifying way, and at the same time, the Yellow Sand City in front of these seven people also changed from golden to black city, and even the sky above the city had wisps of black lines!

"Frame-by-frame animation, ah, this is!"

After seeing the angle changes of the Seven Buddha Diagrams, Dashan said this in surprise.

"What frame-by-frame animation?"

Although the Moon Sect Master knew that on this painting, it must be the painter who used techniques that he didn't understand to create this kind of painting style that could change, but how to describe it, our Moon Sect Master didn't know this at all.

But Dashan knew, and besides, the clever Dashan didn't use those terms to explain to Yuebai, but asked the Moon Sect Master if he remembered the popular copper-boxed razor more than ten years ago.

"Remember, I have another one!"

"Do you remember, on the shaver box, there is a plastic card with a drawing? And the painting on the plastic card will move! ”

"Isn't it the kind where when you look at it from the front, and when you look sideways or from the bottom, the picture on the card changes again?"

"yes, that's it!"

Dashan slapped his thigh and said excitedly: "That's the earliest frame-by-frame animation, which can be frame-by-frame, not called this name, it's actually called raster effect, which is the refraction of light, as well as the visual position of the eyeball, reflecting the two paintings of one light and one dark, one showing and one hidden." Later, some people learned this effect, and began to draw some single pictures on a blank book, and there is a picture on each paper, but each picture is slightly related to the one below, or a change in action, and when you quickly flip this book full of single pictures, those pictures are like having movements, this is a frame-by-frame effect, and it has also evolved from the raster effect. ”

For this kind of technique, or modern high-end products, and interesting things, our Moon Sect Master still has some ears, but like Dashan understands it so thoroughly, Yuebai can't do it.

However, the Moon Sect Master did know about a multi-layered manifestation in ancient times.

This multi-layered display is also an adjective of painting, which refers to the fact that a painting has several layers, and the picture and content of each layer and each layer are placed in different places with different lighting, and the picture and content displayed on the surface will be different.

However, if you put this kind of multi-layered display into the water, then the painting on the first layer will disappear, but if you put it in a dim place, or in a low-light, backlit place, the picture on the first layer will still disappear, but what appears at this time is the third layer, or even the lower layer.

Of course, this multi-layered display, except for the picture on the first one, remains unchanged in the normal environment, then each layer below, if you want to see them, you have to use the way of making the multi-layer display and the way it is designed, otherwise, in the eyes of ordinary people, if the multi-layer display does not change the picture, then it is an ordinary painting.

And this phenomenon, in today's terms, is actually using the reaction effect of different inks, such as adding silver octopus body fluids to the ink, which is a rare silver octopus, then this ink becomes a kind of silver fluorescent water similar to modern times.

Also, if you add pearl powder to the ink, it will also have a different fluorescent effect of other colors.

However, the seven Buddha drawings on the roof of this house are obviously directly painted on the roof of the physical house, and it can neither move nor make any changes, so in this case, it is definitely not using the multi-layered display.

These eighty percent, just like what Dashan said, can use different parameters such as angle, color, viewer's position, and the illumination point of the light source to form this phenomenon, a painting, and many changes.

But no matter what you say, no matter what kind of method the color picture on the roof is used, this rare phenomenon is formed, anyway, at least the meaning of this Seven Buddha Picture, the Moon Sect Master and Dashan can see it.

And it clearly says: The first to understand the hidden search of Huangsha City were seven Buddhists, who saw the panorama of Huangsha City in the morning, noon, and evening respectively because of the coincidence of time.

Moreover, these seven monks who possess the Dharma also saw the difference between day and night in Huangsha City, as well as the yin and yang changes in the city itself, because of their magical powers!

"If this picture had been available for a long time, wouldn't it be a secret that the people who came to Huangsha City would have known it to everyone!"

At this time, the Moon Sect Master thought that since the Master of Compassion knew this secret, then he would definitely tell the others, after all, at night, there would be evil things in this city, and the people in the city also needed to know this, so they could prepare early.

"Well, Boss Yue, you're right, this secret shouldn't be a secret!"

Dashan also echoed: "This picture of the Seven Buddhas is so obvious here, it is impossible for anyone not to notice, and the windows and doors corresponding to it are just right to be outside, and you can see the roof inside through the windows at just the right angle, so this secret is definitely not a secret." ”

"But what's the use of knowing that?"

Yuebai frowned and muttered: "This picture seems to have changed with the town and city well of Huangsha City, and there doesn't seem to be much relationship between the two, I really can't understand why the yin and yang ventilation of a well has changed again and again?" ”
