After listening to Crazy Six's explanation, we didn't speak, this kind of strange crystal, I'm afraid even my cousin has never heard of it.

"If this is the case, a mystery that has plagued the archaeological community for a long time will be revealed, archaeologists are not geologists after all, the crystal, and the stone is too similar, therefore, they can't tell at all, and, the words displayed on the font, I also saw with my own eyes today, the color of the font, and the shadow is almost exactly the same, no wonder all archaeologists think that what appears on it is just a projection."

After a long while, my cousin breathed a sigh of relief and said with some emotion.

The madman said very modestly: "Oh, I'm just guessing, as for whether it is or not, it still has to be tested to be finalized." ”

"Yes, the test will soon be confirmed, in fact, it should be very simple, wait for tomorrow at noon, let's go to that pit again, in the sun, and as soon as those six words appear, we will quickly cover the sunlight above, if it is really a shadow, as soon as the sunlight is covered, the six words will disappear immediately; But if it is really a crystal display, after the sunlight is blocked, those six words will not disappear immediately. ”

Kenya concluded, and Madman Six looked at her and nodded, and suddenly, his eyes lit up again, as if he had thought of something, and said: "By the way, I remember, the professor once told me that the words on this crystal can not only be displayed by sunlight at a certain angle, but if you pour alcohol on it and light it with fire, the words on it will also appear, but the font displayed in this way will not disappear anymore." "When everyone heard that there was still this method, they couldn't help but get excited.

Mr. Chen said, "I have a lot of alcohol, let's try it now." ”

As he spoke, he stood up and took out a large bottle of alcohol from the cabinet in the back - even for plant researchers, alcohol is indispensable when doing a lot of practical work.

"In that case, let's try it now", Maniac Six said, and everyone immediately stood up, ready to go back to the crater and burn the stone with alcohol to see if those words could really appear.

But for some reason, only my cousin sat there without saying a word, as if he was still thinking about something.

Except for him, all of us are a little emotional. Because the "stones" and fonts are strange and wonderful to us, and since they can immediately verify our speculations, how can we not be eager to try it?

Because we were worried about that special infrasonic whistle, we were going to let the two "monkey eagles" stay at home, so that when they heard that kind of infrasound, they would go crazy and burrow into the hole.

But just as we were about to go out, my cousin suddenly shouted, "Wait, don't go yet." Everyone immediately stopped, and looked back at my cousin, who was still sitting firmly in his chair, and beckoned us to sit down first.

We didn't know why my cousin stopped us, but we knew that there must be a reason for him to do so, so we suppressed our curiosity and impulses and sat down in our seats.

My cousin didn't speak immediately, but glanced at all of us before he said slowly, "Do you realize?" If you do ignite alcohol to try it, it can be very dangerous. ”

Hearing my cousin say this, everyone was stunned for a moment, and then looked at each other, not knowing why my cousin came to such a conclusion.

Hongmei asked her cousin tentatively, "Did you say that the gas in that pit would explode when the alcohol was ignited?" My cousin nodded slightly.

We were all taken aback, and before I could think about it, the female translator asked, "How is this possible?" I remember Mr. Chen, who smoked in that pit, but nothing happened, so why did it explode this time? ”

Mr. Chen on the side nodded again and again, and everyone also felt that the female translator's questioning was reasonable.

The cousin was not in a hurry to refute, but calmly waited for the female translator to finish asking before he said slowly: "You are right, but what you don't know is that alcohol reacts strangely when it encounters that gas. ”

Everyone was confused by what their cousin said, and no one understood what their cousin said.

And when everyone was stunned, my cousin stood up first and said, "Let's go, let's go to the crater in the back, Mr. Chen brings alcohol, and I will show you on the spot to explain it more clearly." ”

Everyone is even more confused, just now they stopped us from going, and now they want to take the initiative to go, why is this?

But when my cousin got up and walked out, we didn't have time to think about it, so we all went out, and at this moment, two Japanese female assistants who were walking nearby also came back, it turned out that the two of them did not go to the crater with their cousin, but went to the mountain in front to take a look, and they came back, just with Mr. Chen's wife, staying at home together, taking care of the two 'monkey eagles', and all the rest of the people walked to the crater behind.

What makes us wonder is that before leaving the house, my cousin took a spoon for scooping soup, and the spoon was the size of a fist.

Seeing that my cousin was still immersed in thought, we didn't ask much, and as for the purpose of the spoon, even if we didn't ask, we would definitely know it later.

When we came to the crater, for some reason, my cousin told us not to go in first, and he asked Mr. Chen to pour alcohol into the spoon until the spoon was full.

We stood by, even more confused, not knowing what my cousin was going to do, and my cousin took the spoonful of alcohol and said, "Look carefully." ”

After finishing speaking, I saw that as soon as he raised his hand, the spoonful of alcohol was spilled out, but a strange thing happened, as soon as the spoonful of alcohol was thrown on the top of the stone pit, it disappeared in an instant, and not a drop fell into the pit.

We were stunned!

It's like magic, how can it be?

Not only that, but when Maniac Six pulled back the spoon and let us take a closer look, we were even more surprised to find that there was not a trace of alcohol on the spoon.

What's going on?

"Did you do this to show us how strong the air above this crater is, how strong it is to vaporize alcohol?" Xiao Lei seemed to have guessed his cousin's intentions.

But my cousin seemed to have something to do, and before he could answer Xiao Lei, he said to us: "You guys retreat." ”

Everyone did as he commanded, took a few steps back, and he didn't seem to be satisfied with the distance we had retreated, and said, "Go back again."

We retreated four or five meters back, only he stood on the edge of the pit, suddenly, my cousin struck a match, and then threw it into the pit, just when the lit match, the moment it touched the air above the pit, we heard a bang, a huge air flow rushed towards us, but because the distance was relatively far, so it was not hurt, but I felt that the air flow, very strong, even the eardrum was shaken out.

My cousin was so close that he stumbled and fell to the ground, and we were taken aback and rushed to help him.

After a while, I felt that my hearing was slowly returning to normal, fortunately, my cousin was fine, and the fall just now was not entirely the impact of the airflow, but he consciously fell to the ground by himself to reduce the damage caused by the airflow.

After a while, when everyone calmed down, my cousin explained in detail that the upward air flow in this crater is extremely evaporative to alcohol, and as long as the alcohol comes into contact with this air flow, it will be evaporated instantly.

How did my cousin know this?

It all started with a friend of my cousin, who was from the Institute of Archaeology.

One day, this friend of his happened to excavate that strange Spring and Autumn tomb, but while working in the stone pit at the exit of the ancient tomb, his hand was accidentally cut, and he was cut during the excavation of the tomb, and he must be disinfected with alcohol, because there are often various germs in these tombs, and some germs can lie dormant for hundreds of years, or even longer, and if infected with these germs, it is often fatal.

So, my cousin's friend took out the alcohol, opened the lid, and prepared to use a cotton ball to disinfect it, but the moment he opened the alcohol bottle, the original full of alcohol disappeared all of a sudden.

This surprised him, and he immediately realized that the gas in the pit has an incredible evaporation ability for alcohol, and once the alcohol comes into contact with this gas, it will evaporate instantly.

However, it is said that when the alcohol evaporates into the air, there should be a strong smell of alcohol, but strangely, there is no smell of alcohol at all.

What's going on? It should be that the alcohol and the gas in the pit have some kind of chemical reaction and become another gas, so the smell of alcohol will disappear completely.

While thinking about it, my cousin's friend subconsciously struck a match and wanted to light the cigarette, but at the same time as the match was struck, with a loud noise, he was stunned by a huge air current.

After a few days of rescue, he was out of danger, but he was left with the sequelae of Yan zhòng, the vision of both eyes was affected by Yan zhòng, almost close to blindness, and the hearing in both ears also deteriorated severely.

After listening to my cousin talk about this, we felt very afraid, if it wasn't for my cousin stopping us, that kind of tragedy is very likely to happen to us, because Mr. Chen is a big smoker, usually when he enters the crater, he will hold a cigarette in his hand, and if this large bottle of alcohol is ignited after volatilization, it will be terrible.

It seems that this crater is full of unexpected mysteries.

"Look, everybody, the stone seems to have cracked, and an egg is rolling out," Kenya exclaimed.

We hurriedly looked into the pit, and sure enough, the stone where the word appeared actually cracked at this time, and there was really a white egg inside, but that egg was much smaller than the egg of the giant eagle, only the size of two or three fists, so what kind of egg was it? How can it be wrapped in stone?

Why did that stone suddenly crack? Was it the shock of the air current? Or is it because of something else.

The energy of the spoonful of alcohol just now should have been ignited and released by my cousin, and there should be no danger if I go down at this time, so Mr. Chen put the bottle of alcohol on it, and then we went down to the crater together to carefully observe the stone that had cracked, and the hole drilled by the "monkey eagle".

To our shock, the hole was nowhere to be found, and we searched for a long time in that place by impression, but found no trace of it.
