Seeing this, I used my mobile phone as a flashlight again, and took a photo of the inside of the burning bowl. Sure enough, there was a lot of space inside, enough to hold more than ten catties of fuel.

All right!Now to reveal the truth.

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

The principle is to use the air to expand when heated to generate air pressure, and the high-temperature airflow quickly passes through the tube with a small opening to make a corresponding sound.

To put it bluntly, it is actually very simple. After a little research on my own, I can find two pictures on the Internet, and I can make it at home.

It's just that the relationship between the environment and the atmosphere has affected most people, so that many people don't know the truth and are kept in the dark, thinking that they have offended some unknown gods.

I shook my head and smiled, and was about to stand up and tell everyone the truth.

Suddenly, there was another scream.

"what……"

The scream came from Qin Qin.

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

I heard what Qin Qin said, and sure enough, at the corner of the wall three meters away from the beast's head, a twisting long strip suddenly appeared.

I was quite close to this thing, so I took the courage to take a step forward and took a photo with my phone.

Swish!

The guy stood up, opened a pair of scary fake eyes, and kept spitting at me.

Mr. Cobra!

Why did you come running in?

Looking closely, there seems to be a small hole just exposed in the wall, which is probably consistent with the sound-generating mechanism just now, and it is because of this that Mr. Cobra can show up.

During the analysis, Xiao Kong showed his head again, and then another King Cobra appeared.

"Ah..." everyone shouted.

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

high tower……

Twenty of them, more than one meter above the ground, not counting Lao Mo, happened to be one for each of them. Oh, what a coincidence this design is.

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

The moment my body was on the high platform, I instinctively felt the platform sink.

It seemed to drop a few centimeters.

Without thinking too much, I stepped onto the stage.

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

I took the phone and shook it, and sure enough, two lines of traditional Chinese characters were engraved on the stone platform.The general idea of ​​the letter is "Do you want to escape from this place? If you want to, you should kowtow a thousand times to the image of the Nine Heavens Xuannv, with reverence in your heart. After the salute, the sea of ​​fire will burn the snake, and the gate will open."

When I saw this place, I found that someone was already kneeling on the stone platform, kowtowing to Zhang Qin, the master of Han Baiyu.

I didn't move.

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

We look at each other.

After a while, Lan Xue'e twitched the corners of her mouth: "Brother, it's evil, or else, knock it off."

Sitting carelessly on the stone platform, Jin Ziping shook his legs and said, "Comrade Lan Xue'e, your willpower is too weak. This is obviously a trick."

Lan Xue'e was startled for a moment, but finally she replied confidently: "What means, you can tell me."

I watched these two people quarrel, and after I glanced, I suddenly found that there seemed to be a layer of oil on the ground.

Well!The agency is here.We went up to this stone platform, the stone platform sank, turned on the switch, and pressed the oil out.Then kowtow...

kowtow?

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

I took my hand, pressed it lightly, and listened attentively.

click!

What's happening?It's like the sound of winding up a toy car when we were young.

There is a door!

I groped, and sure enough, I found that the stone platform under the stone slab had about half a centimeter of gap.

I grabbed the slate and pulled it hard.

With a crisp click, I pulled the slate down.

He took out his phone and shook it inside.

Well, the pin device is undoubtedly exposed!

Under the stone slab is a hand-made barrel. Through the holes in the box, it can be seen that there are circles of black steel springs inside. The spring is connected to another control switch through gears, which controls the sinking of the entire stone platform. gear set.

This thing is very well done, once the head is knocked, the mainspring is tightened, and at the same time, the gear set at the other end of the mainspring will turn the last small gear.A steel tongue is stuck on the pinion, and when the steel tongue falls to the lowest point, it will slide away, and then the whole stone platform will sink.

Looking carefully, the entire power system also adds the weight of the human body, because without the weight of the human body, the steel tongue will not slide away by itself in the end.

High!

Such a clever ancient mechanical design reminds me of a vanished industry, Yanshi.

When Yanshi is mentioned, everyone may think of a place name.There is indeed such a city in China called Yanshi.

But the Yanshi I am talking about comes from a record in an ancient book. It is said that King Mu of Zhou traveled across the Kunlun Mountains and arrived at a place called Yanshan Mountain.The little brother can sing and dance, but in the end, he even teased the concubine next to King Zhou Mu with his eyes. The king was angry and wanted to kill him.The man said, I'm not a real person, if you don't believe me, look, after I said something, I cut open my little brother's stomach, and it turned out to be a dummy.

And the name of the craftsman who presented the mechanism dummy is 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 was descended from descendants.It's just that his descendants have a set of ancient teachings that are not disclosed, so the craftsmanship has always been passed down from generation to generation in a non-public manner.

The mechanism under the stone slab is extremely ingenious, there are many, even my little Taoist doctor, who has always been good at physics in high school, doesn'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 bang bang!

I looked up and saw, good guy, everyone is crazy and addicted to kowtowing.

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

I looked around and saw Vivian, Jin Ziping, and Lan Xue'e looking at me in horror.

Yes, they couldn't figure out how there could be such an exquisite mechanism combination under the stone platform.

I didn't say much, after thinking about it, I picked up the stone slab and knocked it hard against the stone platform, bang!The slate was broken, I found a slightly sharp piece, put it into the mechanism, and poked the little steel tongue stuck on the gear hard.

boom!

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? Come on! Do it with me!"

His roar had an effect, many people stopped kowtow, turned around, and stared blankly at Jin Ziping.

Xiao Jin imitated me, opened the stone slab, and smashed it again. When it was over, he pointed at the outer steel tongue and gave it a hard push.

boom!His stone platform also sank.

A few male students immediately understood that they were busy working like Xiao Jin.

Xiao Jin and I were not idle either. We jumped from one stone platform to another, helped everyone, opened the mechanism, and then pressed against the little steel tongue, boom boom boom...

The stone platforms sank like this, and finally, when the last stone platform sank.

A guy on the ground blew up a string of flames.

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

And just 10 minutes after the sea of ​​fire burned, the door on the other side of the secret room slowly opened.

While opening it, I noticed that near the door hinge, there were wisps of white steam gushing out.

Looking at the ground again, you can also find that the flames are all coming out from the joints of the floor tiles.

This is another complex steam door principle.

Use fire to boil the water in the ground, and then use the steam pressure to open the door.

In the sea of ​​fire on the ground, there was only one aisle, which was as wide as one person.Seeing this, I said to everyone: "Hurry up, everyone, jump up this aisle and leave this room."

After listening to the words, everyone jumped carefully among the stone platforms, and then came to the ground one after another, trotted out of the room, and entered another room.

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

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

I was the last to enter the other room.

Looking at the sea of ​​flames and the slowly closing door, I was filled with emotion.

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

What this person has can no longer be described by skills.In addition, what he pursues is definitely not money, but a spirit, a spirit that releases his own skills.

Think about it, if you have the best skills in your body, but you have nowhere to release them because of some ancestor's precepts, are you panicking?And once someone promises money and lets you do something with your own skills, don't you have to be overjoyed?

A crazy woman who is arrogant, rich and beautiful, and then meets a man who has top-notch mechanical knowledge!

All right!When these two kinds of people meet, I feel that this secret room is just a child's play!

At this moment, the door slammed shut.

I breathed a sigh of relief, and when I was about to look at the layout of the room, suddenly, a sound of quarreling came into my ears.

A few female students surrounded Jin Ziping and asked sharply, "Why did you sabotage Instructor Zhang's arrangement? Do you know how much effort Instructor Zhang spent arranging such a course for us to suspend? You know, you sabotaged Have you missed our journey of physical and mental breakthrough? You pay us tuition!"

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

The sheep rebelled!

More and more people surrounded him, even many male students joined the ranks, surrounded Jin Ziping, and kept shouting and asking questions.

I have to say that Zhang Qin is amazing.

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

Yes, this matter is not illegal!No violation of the criminal law, what happened to the secret room I arranged, no one was hurt, it was all safe and sound, I didn't indoctrinate you, if you want you to believe me, I just did a normal little trick.

And this is precisely one of the most terrifying methods of boiling frogs in warm water.

Being in it, I still don't feel that this person is bad, but I feel that he (she) is good, so I accept it again and again, until one day, when I can't pull it out, I have already boarded the thief's ship.

Zhang Qin's way is to be subtle.She did not directly explain, but through a series of man-made incidents, each student automatically accepted the theme that she is a 'God'.

I saw that Jin Ziping was overwhelmed.

I gave Vivien a wink, and the latter understood, and went to the front with me and said, "Everyone, calm down! This is actually not a so-called spiritual practice at all..." After I finished speaking, I told Zhang Zhang what I knew. Qin, I told everyone.

"Fart! You are farting!" Several female students were aggressive.

"This person is a high-level hacker, he must have come from another spiritual training class to slander Teacher Zhang."

"Yes, he is Senior Black."

Vivienne was very angry at this moment, her eyes moved, as if she wanted to speak.

I stopped her now.

Unless it is absolutely necessary, her identity as a policewoman must not be revealed!

At this time, I saw two forks in the road ahead, so I cupped my fists and said to everyone: "Everyone, I'm sorry, I did this. I'm sorry! I surprised you. Vivian, let's go!" After speaking, I led Vivian, Jin Ziping, and Lan Xue'e to the front.

After walking a few steps, suddenly, I saw Qin Qin, a young white-collar who was bitten by a snake, sneak away from the crowd and followed behind us...
