I put all the forty small pieces of paper in it, and then I picked them up one by one and put them together like a puzzle...

"Are you stupid?" The fat man looked at my every move strangely from the side.

"Look carefully." I looked excitedly at the piece of paper I put together on the table and said to the fat man.

The fat man rubbed his sleepy eyes and lay down...

"Map, Zhilong, this is a map..." the fat man shouted in dismay.

The forty small pieces of paper on the desktop were piece by piece according to the size of ancient books. Since they were all wet, they all became transparent. Then the curved lines on the paper were all revealed, and these curved lines could be connected to the end, forming a complete map...

I grabbed a pencil, threw it to the fat man, and said to him, "Click it down..."

Then I turned around and hurried to find the ancient book. I took out the ancient book from the safe. I hurriedly opened the book, found the strange word on each page, and then put my hand on it and gently stroked it...

When my fingers slide through these strange words, I feel a slightly protruding line. I quickly took the flashlight and lifted up every page of the ancient book and illuminated it...

"I've finished drawing, what did you find?" The fat man gave me the map he had just drawn and said anxiously.

I took the map and murmured, "I understand, I understand..."

"What did you understand?" The fat man was almost in a hurry.

I picked up the ancient book and shone it on one page from the side with a flashlight, and said to the fat man: "Look carefully on the other side." The fat man looked down and screamed: "I understand too."

Under the flashlight, there is a small protrusion that is not easy to see in that strange word. If you look at it on the plane, you can't see it at all. Only when the light passes through the book and passes through the light on the other side can you see it. This is why there are curved lines on those small pieces of paper.

Because of these protrusions, the laser is reflected by these small protrusions during scanning, and the curve is scanned out. However, because these small protrusions are too insignificant, it cannot be noticed at all.

However, if you look at the ancient books directly through the lights, it will be very clear.

"Yes, it's a map." I said to the fat man excitedly.

"Someone hid a map on this book, divided the map into many parts and hid it, and then applied a layer of light-absorbing paint and some ingredients exactly the same as the color of the book on each page. In this way, this book can only be understood when it is passed through the light..." I was so excited that I even changed my tone.

"It seems that the person who wrote this book wants future generations to discover this map. What does this map contain?" The fat man finally thought about things with his brain this time.

"I don't know... I don't know... It's so strange. First, there are strange books, then the Western Han Dynasty characters actually appeared in the books of the Ming Dynasty, and then the strange mysterious people. Now it's a strange hidden map..." I murmured.

I suddenly thought of something and immediately grabbed the map that the fat man had just drawn...
