Fatty is right. At this time, the basic knowledge I learned before is very crucial. If many people don't understand basic physics, they often only notice how the building appears in the mirror.

But I know that the most bizarre thing about this mirror is not here at all.

A mirror needs a light source to reflect things. Where there is no light source, the mirror will not have any reflective points.

But the ancient building in the mirror is shrouded in a miserable blue light. This light is not our light source, but the light source emitted by the ancient building itself.

The light source comes from inside the mirror.

This means that as long as I turn off the flashlight, the only light source in the entire cave will be these green lights. The green light will shine through the mirror and illuminate the place blue.

But when we first entered, the cave was pitch black. No light emanates from the mirror.

"Turn off the lights." I said to the fat man, and immediately turned off my flashlight.

The entire cave suddenly darkened. According to normal physical conditions, the green light in the mirror should become the main light source at this time.

But now the entire mirror suddenly went dark, and the cave turned into absolute darkness, with only the fluorescent sign on Fat Man's flashlight glowing.

"Pop", the flashlight turned on again.

Looking in the mirror again, the inside is still the same as what we saw before. The bleak old building was as quiet as a fossil.

The fat man asked me what I was doing, and I told him roughly my theory. He didn't understand, but he understood the purpose of my experiment, and said to me: "Just tell me the conclusion, you are naive, don't be polite to an illiterate like me."

"This shows that this phenomenon has nothing to do with the propagation of light. As long as a light source shines on the mirror surface, the mirror will activate and display an image.

But as far as I know. There was no photosensitive technology in ancient China.

According to records in ancient China, mechanisms that use light to open generally use the phototaxis of animals and are short-term mechanisms. Usually they are handicrafts for fun. "

I said, "It's a good thing that ancient China didn't have this technology. Otherwise, we would have had to fight in the dark in the ancient tomb, and a torch would trigger all the mechanisms."

"What you said is all in vain." The fat man touched his chin, "Aren't you just telling others that this mirror is awesome and you don't understand what's going on?"

"That's different. I'm reasoning from the principle, which can save a lot of unnecessary thinking. You let me think about it. I believe that great proletarian warriors will not be defeated by strange forces and gods.

All phenomena have their natural phenomena behind them. "

I was a little annoyed by what he said, so I asked him to stop talking.

"Steal my lines." Fatty muttered, "Okay, you think about it, Fatty, I'll take a cigarette." After saying that, he huddled up on the beam and lit a cigarette.

I chuckled, it was finally time to unite the fat man, and thinking about it, I looked at the mirror again.

To be honest, I do think this mirror is too awesome, but based on my understanding of some ancient Chinese craftsmanship techniques. This must still be understandable to us.

Some skilled craftsmen in ancient China had advanced craftsmanship skills, but they were still craftsmen. Rather than becoming a real ghost.

Therefore, what we see with our eyes is often like a miracle, but if we say it clearly, it is often just a "deception".

The first thing to consider is, if I were to make this mirror myself, what method would I use. I ran my flashlight across the mirror.

Looking at those light source points, I suddenly thought of a test method that the teacher said when doing experiments before.

A phenomenon must have a beginning and an end. Sometimes the starting point and the end point are not important in themselves. What matters is how the starting point leads to the ending point. Just keep changing the parameters and carefully observe the changes. You can get a lot of clues.

At that time, Fatty and the others were able to enter here through the strange stone path, and they also used this method.

I raised the flashlight and started to twist the aperture of the flashlight. We only had two parameters: bright and dark before. Now I want to see how this mirror changes from the brightest to the darkest.

The fat man turned off the flashlight and cooperated with me. I slowly turned the flashlight to dim. I immediately discovered that the green light in the entire mirror was slowly dimming, and the dimming range was exactly the same as the dimming range of my flashlight.

I slowly turned on the light source, and the green light in the mirror slowly became brighter.

I couldn't help but smile. My superb judgment about this mirror just disappeared. I immediately said to the fat man: "Look, it's not that magical. The green light in this mirror is the light source of our flashlight. Our flashlight is bright. There is light within, and when our flashlight is dim, there is darkness within.”

The fat man could see clearly from the beam and nodded: "Can our flashlight pass through this mirror and reach this building?"

I shook my head. Although our flashlights have "wolf eyes" and can blind people with direct lighting, it is impossible to use them to illuminate such a large building.

I can't fully speculate on the real situation, but since the problem of light in the mirror is so simple, I think other situations must not be too difficult.

My second uncle taught me that everything depends on the purpose. Only by the purpose can we infer many aspects that cannot be predicted from the front. This is the most useful sentence I learned from the older generation.

I touched my legs, which were numb from the cold water, and began to think about the purpose of putting this mirror here.

"Do you think putting this mirror here has anything to do with Feng Shui?" I asked the fat man.

The fat man thought for a while and said: "Some Yangzhai Feng Shui will use the Bagua mirror, but it is too big. If this mirror is hung on the balcony, it can shake down the airplane.

Just sit on the balcony and watch the planes fall all day long. Today there is an Airbus, and tomorrow there is a Boeing. How lively it is. "

"You're jerking off and rocking the plane, you're fucking on the plane, aren't you? We don't have time, let's think more seriously."

The fat man took a few puffs of his cigarette for the last time, pinched the butt of the cigarette and threw it into the water, then lit another one: "If I had thought of it, I would have thought of it long ago, and then rushed into the ancient building.

Save them all, and now we are eating roast duck in Beijing and sucking on cigarette butts. Think more and don't rely on me. "

"Aren't you a master of Feng Shui? Are you still asking me?" I asked him.

He shook his head: "I'm sure I can't do this damn advanced thing. Besides, you didn't understand anything at that time. It's okay for me to talk nonsense. Now that you've made progress, I have to be more careful."

I thought to myself, damn, it turned out that you were just talking nonsense. The fat man continued: "I think it's useless for you to think about Feng Shui. You can understand Feng Shui at a glance.

If you don’t understand even if you are blind, if you really want to hear my opinion, I can tell you that my first reaction was the reflection above, but look at the top. "

He pointed his "Wolf Eye" flashlight above his head. The cave is very deep, and you can see that the top is full of rocks, but you can't see clearly.

I took out a cigarette, pulled it over the fat man's smoking point, and stuffed it back into his mouth. I followed the fat man's flashlight and swung it back and forth above my head.

"It was all rocks and nothing, so I thought, damn, this building is in a mirror."

The fat man stepped on the mirror in a few steps, "If the image in the mirror was reflected from there, it would definitely be blocked if I walked on the mirror. But it didn't.

Compared to you, a college student, I am less educated, but I understand the basic principles. "

I looked at the rocks above, and then at the fat man posing in the mirror. I looked back and forth several times. I felt that what the fat man said was absolutely correct, but something strange arose in my heart.

Maybe it’s because there have been so many deceptions and designs around me recently, so I have a sensitive intuition for the flaws in many things. I suddenly felt that this hole was not rigorous enough.

It's like a magic trick. Speaking of magic, the most awesome magic is street magic, which is performed right in front of you without any disguise.

Magic masters often feel like they have special powers. This is the most powerful.

Then there is the stage magic, but many of the most basic tricks in stage magic require cloth to cover or the use of boxes. The principle is to make others feel that using cloth and boxes cannot change the impossibility of the matter.

But because we know that magic is mostly illusions and traps, smart people will immediately know that the trick must be behind the cloth and box, but it is just very cleverly designed and we don't know it.

This feeling now is the feeling of stage magic. If the design craftsmen here can make it true that the "Zhang Family Ancient Building" is in the mirror.

So, should we look for a shorter cave so we only have to look up. Just know that there is no way to do anything on the roof of the cave.

However, the ceiling of this cave is too high, so it is difficult to see clearly. Although we basically judge that there is probably nothing on the ceiling of the cave.

It's just a stone, but the height makes me think that if there is a one in ten thousand chance, the mechanism will definitely be hidden on the roof of the cave.

Because the situation around us is so obvious that there can be no possibility.

The possibility must be somewhere we haven't seen yet.

Of course, this might just be a momentary illusion on my part, but if anyone told me that you have to unravel a stage magician's trick or you'll lose your friends.

The first thing I had to do, of course, was to kick over the magician's box to see if anything strange was inside.

"We have to climb up and take a look." I said to the fat man. To be continued
