Seeing this, I used my mobile phone as a flashlight again, and took a picture of the bowl that had just burned, and sure enough, the space inside was very large, enough to hold more than ten catties of fuel.

All right! Now to reveal the truth.

This thing, in fact, existed in ancient times, and most of them were used to scare people.

The principle is to use the air to expand by heat to generate air pressure, and the high-temperature air flow quickly passes through the tube with a small opening, so as to make a corresponding sound.

To put it bluntly, it's actually very simple, I have studied a little, found two pictures on the Internet, and I can make them at home.

It's just that the relationship between the environment and the atmosphere affects most people, so that many people don't know the truth and keep it in the dark, thinking that they have provoked some unknown god.

I shook my head and smiled, just about to get up and tell everyone the truth.

Suddenly, another scream.

"Ah......h

This scream was made by Qin Qin.

"Snake, snake! There are snakes on the ground! ”

I heard Qin Qin say this, and sure enough, in the corner of the wall three meters away from the beast's head, a writhing strip-like object suddenly appeared.

I was pretty close to this thing, so I got the courage to take a step forward and take a picture of my phone.

Swish!

The creature stood up, opened a pair of frightening prosthetic eyes, and kept spitting messages at me.

Cobra-kun!

Did you run in swollen?

Looking closely, there seems to be a small hole in the wall that has just been exposed, which is estimated to be consistent with Fang Cai's sound mechanism, and because of this, Cobra-kun was able to appear.

During the analysis, Xiao Kong's head was exposed again, and then another cobra-kun appeared.

"Ah......h

I don't know who shouted, and ran to the high platform.

Profile......

Twenty, more than a meter high from the ground, not counting Lao Mo just one person, ouch, this design is really clever.

I didn't want to provoke Cobra-kun, so I picked a platform with everyone and climbed up.

The moment my body stepped up to the platform, I instinctively felt the platform sink.

It seems to have fallen a few centimeters.

Without much thought, I rolled over and went on stage.

At this time, someone said, "Look, there are words on this stone platform." ”

I took my phone and shook it, and sure enough, two lines of traditional Chinese characters were engraved on the stone platform. The gist of the book is, "Do you want to escape from this place?" If you want to, you will kowtow a thousand times to the statue of the Nine Heavens Xuannu, with reverence, after the salute, the sea of fire will burn the snake, and the door will open. ”

When I saw this, I found that someone was already kneeling on the stone platform, kowtowing to the naked white marble Zhang Qin.

I didn't move.

Vivian, Lan Xue'e, and Jin Ziping didn't move.

We looked at each other.

After a while, Lan Xue'e twitched the corners of her mouth: "Dude, evil deeds, or knock it." ”

Jin Ziping sat on the stone platform and dangled his legs and said, "Comrade Lan Xue'e, your willpower is too unstrong, this is obviously a means. ”

Lan Xue'e was stunned for a moment, and finally replied confidently: "What means, you say it." ”

I watched the two men arguing, and I glanced behind me, and suddenly I noticed that there seemed to be a layer of oil on the ground.

Okay! Here's the mechanism. We went up to this stone platform, and the stone platform sank, and the switch was activated to press the oil out. And then kowtow......

Kowtow?

I looked closely at the front of the stone platform, and then I found that the place in front of the stone platform for people to kowtow turned out to be a separate stone slab.

I took my hand, pressed it gently, and listened intently.

Click!

What's going on? It's like the sound of winding up a toy car when we were kids.

There's a door!

I fumbled around, and sure enough, I found that there was a gap of about half a centimeter in the stone platform under the stone slab.

I grabbed the slate and pulled it outward.

With a crisp click, the slate pulled me down.

I took out my phone and shook it inside.

Well, the pins are exposed!

Beneath the slate is a handmade barrel, through which a circle of black steel springs can be seen, and the clockwork is connected to another control switch through the gears, which is the gear set that controls the sinking of the entire stone platform.

This thing is wonderfully done, kowtow, the spring tightens, and at the same time, the gear set at the other end of the spring will turn the last pinion pinion. The pinion is stuck with a steel tongue, and when that steel tongue falls to the lowest point, it will slide away, and then the whole stone platform will sink.

If you look closely, the entire power system also adds the weight of the human body, because the weight of no one's body is pressed, and the steel tongue will not slide away on its own in the end.

Tall!

Such a clever ancient mechanical design can't help but remind me of an industry that has disappeared, Yanshi.

As soon as Yanshi says it, everyone may think of a place name. There is indeed such a city in China called Yanshi City.

But the Yanshi I am talking about comes from a record in an ancient book, saying that King Zhou Mu traveled across Kunlun Mountain and arrived at a place called Yishan. The little brother can sing and dance, and in the end, he actually teased the concubines beside King Zhou Mu with his eyes, and the king was angry and wanted to behead. The man said, I'm not a real person, I don't believe it, I spoke, I opened the little brother's belly, and I saw that it was really a dummy.

And the name of the craftsman who offered the dummy was Yanshi.

At the beginning, I saw a document at the bottom of Gaoligong Mountain and in the secret place of the family, which said that this Yanshi had a descendant. It's just that his heirs have a set of ancient precepts that are not revealed, so the craft has always been passed down from generation to generation in a non-publicized way.

The mechanism under the slate is extremely ingenious, and there are many, even I, a Taoist doctor who has always been very good at physics in high school, don't understand it very well.

From this, I guessed that the person who helped Zhang Qin design the whole system was definitely a Yanshi!

At this time, bang!

I looked up and looked, good guys, everyone is crazy, kowtowing and getting addicted.

Yes, this is the herd effect of human beings, in fear, as long as one person takes the lead and does something, then the rest of the people will immediately follow, without thinking about it.

I looked around and saw Vivian, Jin Ziping, and Lan Xue'e looking at me with a look of horror.

Yes, they couldn't figure out how there could be such an ingenious combination of mechanisms under this stone platform.

I didn't say much, I thought about it, I picked up the stone slab, faced the stone platform, and slammed it hard, pop! The slate shattered, and I found a slightly sharp shard, reached into the mechanism, and stabbed the little steel tongue that was stuck in the gear.

Rumble!

The stone platform I was sitting on sank more than half a meter deep.

Seeing this, Jin Ziping understood, and immediately stood on the stone platform and shouted: "Don't kowtow, is your head so easy to knock?" Do you know what that white marble looks like? Fast! Do it with me! ”

His roar worked, and many people stopped kowtowing and turned around, staring blankly at Jin Ziping.

Xiao Jin followed my example, pulled open the stone slab, smashed it again, finished, aimed at the outer steel tongue, and made a hard push.

Rumble! His stone platform also sank.

A few male students immediately understood that they were busy working for a while.

Xiao Jin and I were not idle, jumping from one stone platform to another, helping everyone, getting the mechanism open, and then resisting the small steel tongue, boom boom......

One by one, the stone platforms sank like this, and eventually, when the last stone platform sank.

When the ground shook the ground, a string of flames rose up.

Then the flames connected into a sea, and the dozens of cobras that sprang out instantly turned into roasted dried snakes.

And just ten minutes after the fire burned, the door on the other side of the secret room slowly opened.

As I opened it, I noticed a wisp of white steam gushing out near the door shaft.

If you look at the ground, you can see that the flames are coming out from the joints of the floor tiles.

Again, this is a complex steam gate principle.

Using fire, the water in the ground is boiled, and then the door is opened with the help of steam pressure.

In the sea of fire on the ground, there was only one aisle, more than one person wide. Seeing this, I said to the crowd, "Hurry up, everybody, jump up this aisle and leave this room." ”

Hearing this, everyone carefully jumped between the stone platforms, and then, one after another, came to the ground, trotted out of the room, and entered another room.

I was the last to jump off the stone platform, and just five seconds after I left the stone platform with both feet, the door was about to slowly close again.

However, the closing process was extremely slow, and there was enough time for two dozen people to leave.

I was the last to enter another room.

I looked at the sea of fire, the slowly closing door, and I felt endless emotion.

This Zhang Qin is not very good, but the person she invited is too powerful.

What this person has can no longer be described as skill. In addition, what he pursues is not money, but a spirit, a spirit that unleashes his skills.

Think about it, if you have a heavenly stunt, but you have nowhere to release it because of some kind of ancestral teaching, do you panic? And once someone promises money and asks you to do something with your skills, do you have to be overjoyed?

A female madman who is arrogant, rich, and has a beautiful woman, and then meets a male dick with top-notch mechanical knowledge!

All right! When these two people met, I felt that this secret room was just a pediatric!

At that moment, the door slammed shut.

I breathed a long sigh of relief and was about to take a look at the layout of the room when suddenly a quarrel came into my ears.

I saw several female students surrounding Jin Ziping and asked sharply: "Why did you sabotage Tutor Zhang's arrangement, do you know how much effort Tutor Zhang spent to arrange such a course for us to suspend the test?" Did you know that you ruined our journey of physical and mental breakthrough? You're paying us for our tuition! ”

I was stunned, yes, I didn't think of this link at all.

The sheep have rebelled!

There were more and more people, and even many male students joined the ranks, surrounding Jin Ziping and shouting and questioning.

I have to say, Zhang Qin is amazing.

With such a thing, she has always played an ambiguous route.

Yes, it's not a crime! Don't violate the criminal law, what's wrong with me arranging the secret room, no one is hurt, it's all in danger, I haven't instilled it, I want you to believe me or something, I just did a normal little trick.

And this is precisely the most terrible means of boiling frogs in warm water.

In it, I didn't think this person was bad, but I thought he (she) was good, so I accepted it again and again, accepted it again and again, and one day, when I couldn't pull it out, I was already on the thief ship.

Zhang Qin's way is imperceptible. She does not explain it directly, but uses a series of man-made events to make each student automatically accept the theme that she is 'God'.

I saw that Jin Ziping couldn't resist.

He glanced at Vivian, who understood, and came with me to the front and said, "Calm down, calm down!" This is actually not a so-called spiritual ...... at all" After I finished speaking, I told everyone what I knew about Zhang Qin.

"Fart! You're farting! "Several female cadets were aggressive.

"This person is a high-level black, and he must have come from other spiritual classes to smear Tutor Zhang."

"Yes, he's a senior black."

Vivien was so angry that her eyes moved, as if she wanted to speak.

That's when I got in her way.

Unless it is absolutely necessary, her identity as a little police flower must not be exposed!

At this time, I saw that there were two forks in the road ahead, so I clenched my fists and said to everyone: "Everyone, I'm sorry, I did this thing, I'm sorry!" Frightened you. Vivian, let's go! After speaking, I took Vivian, Jin Ziping, and Lan Xue'e and walked straight to the front.

After walking a few steps, suddenly, I saw Qin Qin, a little white-collar worker who was bitten by a snake, secretly leaving the crowd and following behind us......
