Professor Shen yelled badly, but it was too late.

The fat woman's husband had already slashed at the crystal.

This crystal is formed by hundreds of thousands of years of natural changes, although the dagger is sharp, where can it be cut down?

I only heard a loud sound of "bell", and the right arm of the guy who shook directly was numb, and the dagger fell directly to the ground.

At this time, there was a loud "boom" sound from the depths of the crystal cave.

Seeing that the situation was not good, everyone ran into the distance.

Later, the Mexicans discovered the scar on the crystal pillar, believing that someone had tried to remove the crystal, but failed, so they slashed at it with a knife to vent their anger.

Therefore, the Mexican government installed a heavy iron gate at the cave so that outsiders could no longer enter it, so as to better protect the wonder from damage. Of course, that's another story.

But they said that they continued to march along the desert, and walked for more than an hour, and there was no end in front of them, and there was no shadow of the palace.

Everyone was suspicious and didn't know why.

At this time, Byrne saw a huge sand dune on the left, like a hill.

So he said, "Come and climb the dunes with me to see what is going on, and let the others rest here for a while." ”

With that, Byrne and the three boys walked towards the dune.

After waiting for nearly twenty minutes, Bourne saw everyone returning, and Bourne saw Professor Shen with a puzzled look on his face and said:

"It's really strange, the palace is clearly ahead, but the distance is the same as before, and it is not even close at all. ”

Professor Shen pondered for a while when he heard this, and suddenly said, "Could it be that what you are seeing is a mirage?"

"Mirage?" everyone gathered in surprise, everyone had heard of mirage, but they didn't know much about what a mirage was.

Professor Shen looked confused and explained:

"Anything we see is light reflected into the eye. But different objects have different refractive indices. ”

"It's like when we put a fork into a glass of water, you notice that the fork looks like it's broken by water. ”

Seeing that everyone still didn't understand, Professor Shen continued to explain:

"Refraction occurs when light crosses the boundary between two different mediums. ”

"When we are in the desert, light is constantly refracted as it passes through layers of air at different temperatures, which is simply the light walking a curve. ”

"When the human eye receives a curved light, it instinctively thinks it's a straight line. As a result, the image in the human eye will not match the actual position of the object, which creates a mirage. ”

The more everyone listened, the more it made sense, if the palace wasn't a mirage, how could everyone have not arrived after walking for so long?

Unexpectedly, the hope that was full of hope ended up in the mirror, and everyone sat on the ground one by one.

The fat woman was fighting with the lean man at this time, and the woman complained while beating the man:

"I said a long time ago that if you don't take this broken plane, you want to save that few dollars, and now I have fallen into such a field, see if I don't tear you up today. ”

Seeing this, Professor Shen said slowly:

"You don't have to be pessimistic, although the mirage is an illusion of refraction of light, it is not illusory, it is also attached to real objects. ”

When everyone heard this, they all looked up at Professor Shen, and the fat woman's hand slowed down.

Bourne's heart moved, and he hurriedly asked, "What does the professor mean?"

Professor Shen said: "Since the mirage is so real, it means that this palace does exist, but through the refraction of light, everyone goes in the wrong direction and walks along the illusion of light, which is getting farther and farther, and will never be able to go." ”

When everyone heard this, they all came to their senses, and one of them asked:

"You say the palace is real, so where is the palace?"

Professor Shen thought for a moment and said:

"There are many factors that cause light to refract, and in simple terms, the greater the refractive index of an object, the smaller the angle of refraction. ”

Professor Shen looked up at the clouds in the sky and calculated the density of the clouds in his heart. Mouth said:

"For air, hot air is less dense and has a smaller refractive index, and cold air is the opposite. ”

"By the physical factors we are in, we can determine the refractive index and even determine whether there are multiple refractions or even reflections. ”

Professor Shen raised his head and pondered for a while, then suddenly his face was happy, he pointed to the northwest corner, and said, "The palace is there." ”

---------------------------------------------------------------------------------------------------

Over Tijuana Airport, a colorful cloud envelops the planes as they climb upwards.

There was lightning and thunder in the clouds, and the plane maintained an upward climbing posture, but it moved upwards very slowly.

It was dark in the cabin, and the Arab man held a delicate cloth bag in one hand and an oil lamp in the other, shining at the people in the seats one by one.

He started with the fat woman in the back row, and took off the necklaces, bracelets, and rings around her neck one by one.

He pulled off her earrings again, and scolded: "Stinky woman, the color of this chain is good." ”

All the passengers on the plane sat motionless in their seats, their eyes wide open, looking ahead, but their eyes were extremely empty.

Because their consciousness has entered the ethereal desert world under the influence of the oil lamp of the Arabs.

At this time, there was a man whose eyes were rolling to watch every move of the Arab, and he was Gonev.

It turned out that Goonev was sitting on the plane and was a little sleepy, but suddenly the plane was violently turbulent, and the lights in the entire cabin were all extinguished.

Then the plane suddenly fell silent, everyone's surprise and shouts suddenly disappeared, and the whole plane was quiet and terrifying.

Goonev was very surprised, and was about to get up, when he suddenly felt a flash of white light in the cabin, and he turned his head to look at the passengers on the plane.

I saw that everyone was wide-eyed, their eyes were empty, and they were all sitting there like dummies.

Goonev was about to ask, when he suddenly saw the Arab next to Amanda standing up, holding a glowing oil lamp in his hand, standing in the cabin and sneering.

When Goonev saw that the situation was strange, he stopped speaking and watched silently as the Arab moved.

I saw this Arab holding an oil lamp, starting from the back seat to collect gold and silver jewelry from the passengers one by one, and kept approaching him.

The Arab then walked to the back row of Gonev and searched the body of a woman for a long time, who only had a local Mexican craft collar around her neck, and no gold or silver jewelry on her.

The Arab was a little annoyed, lifted the woman's collar, and slapped two big mouths fiercely, and the woman's body was so limp that she was unconscious.

The Arab put down the woman, turned and walked to Goonev, and seeing that Gonev had no jewelry on him, he reached out and touched his pocket.

When he touched his waist, he felt that his tentacles were hard, and when he reached out, he pulled out a gold bar.

When the Arabs saw the gold bars, their faces were overjoyed, and they praised them as they examined them.

Hurriedly reached out to untie the cloth bag around Goonev's waist.

Unable to bear any longer, Gonev glared at him and pressed the Arab's arm against his waist.

The surprise of the Arabs was not trivial, he had been in this business for many years, and this was the first time he had encountered resistance.

It turned out that this oil lamp of his was not an ordinary oil lamp, it was a magic lamp from Agrabah.

It is capable of bringing time and space to a standstill, and then forcing an out-of-body experience, expelling one's consciousness from the body.

To the great shock of the Arabs, it was clear that this stagnant time had no effect on Gonev's body at all, and he was still able to move on his own.

As for why this is happening, the Arabs can't figure it out even if they have their heads broken.

The Arab stammered nervously and asked Gonev:

"You..... You..... You, who are you?"
