It didn't take long for Ouyang and Xiao Liu to feel better,

"I had just listened closely, and I heard the sound of dripping water under the floor, and I heard the sound of birds flying outside. Ouyang said.

"Let you listen to the movement in this room, why do you listen to the birds flying outside. Captain Xiao said,

Zhang Yi motioned to Captain Xiao not to say it yet, and asked Xiao Liu to tell him what he heard.

Xiao Liu said: "I feel a very weak air current, a weak updraft. ”

Everyone looked at the old professor, who was still holding his beard and seemed thoughtful.

Suddenly, his eyes lit up, he should have understood what was going on, and said with a smile: "Have you ever seen a waterwheel in the countryside?"

"Why did the old professor ask this, and does it have anything to do with the waterwheel?" Zhang Yi asked curiously.

The others didn't understand what it meant, but Ouyang suddenly understood, the corners of his face and mouth turned up slightly, revealing a smile,

I didn't expect such a small detail to be discovered by the old professor,

Professor Wang said: "Let Ouyang talk about it, he seems to understand." ”

"Huh?" Ouyang was taken aback at first, and then said, "Teacher, I thought of something, but I don't know if it's right. ”

"But it doesn't hurt to say that. The old professor still meant to let Ouyang say,

So Ouyang said: "What I understand is that the principle of operation of this secret door should be the same as the principle of the waterwheel, which is driven by the thrust of water, and the flow of water provides power to the main shaft of the mechanism.

Today's rain is the driving force behind the opening of this secret door, is that what the teacher means?"

"Yes, that's it," the professor said, and gave Ouyang a thumbs up,

After listening to what Ouyang said, the others suddenly realized,

"It turns out that this mechanism is so cleverly designed, no wonder we can't find the location of the mechanism no matter how we look for it, this Nima design is too good, it really opened my eyes. Captain Xiao exclaimed,

"You know, this is what the ancients saw in ancient times, so it's even more rare. The old professor added.

"Yes, yes, this ancient man is too good!" everyone agreed.

Everyone admires the designers here.

is even more impressed by the old professor, it seems that the three stinkers can't stand up to one Zhuge Liang.

At this time, the old professor spoke: "Xiao Liu, you can feel the gap between the ground and the wall in the secret room, and tell me what the situation is later." ”

"Okay!" Xiao Liu replied and immediately went into the house.

After a while, Xiao Liu came out with some confusion and said: "It's really strange, I didn't feel the air flow in the crack of the wall under the secret door, but I could feel some rising water vapor in the crack of the wall on both sides and the east side." ”

"That's right, the secret door you are talking about has no door at all, it is a stone wall, which will mislead many people to find the opening mechanism,

Or will want to blow in through this so-called secret door, if it really blows up here, it is estimated that this entrance will be closed forever,

Once that wall is blown up, everyone is expected to die here, which may be the designer's purpose.

And you only thought that the door would move, but didn't you think that the house would move?

Each of you is younger than me, how can you think more rigidly than me, it seems that the current education is really too failed, and we teachers are too failed. The old professor said to everyone slowly.

Everyone was a little embarrassed when they heard this,

In fact, the old professor didn't want to talk about them, but he was very dissatisfied with the current education.

The old professor thinks that he is talented, but his research still needs some leaders with backgrounds who don't know anything.

These people don't understand and still blindly guide, you say that our technology and culture can be strong, so I am also dissatisfied in my heart.

"You mean that the house is moving, but how can such a big stone house move? And isn't the whole palace connected? How are you sure that this house is moving?" Zhang Yi asked with a puzzled expression,

The others also looked at the old professor with puzzled expressions.

The old professor smiled and continued: "Just now I asked Xiao Liu to test those wall cracks just now to verify my idea, and now I have been verified, and you can see what is wrong with my clothes?"

This question made everyone confused, why did you suddenly let you look at your clothes?

This old professor made such a sharp turn, and no one followed,

Ouyang said, "What does this have to do with your clothes?"

The old professor smiled: "Haha, you really look at the mountains and mountains, there is no association at all, there is a button missing from my clothes, and it fell here, can any of you help me find it?"

When everyone heard this, they all went to the room to look at it, and the room was spotless.

The room is not big and there is nothing in it, you can know at a glance whether there are buttons on it,

These people seem to understand,

The professor continued, "Yes, as everyone thinks, the button I fell to the ground is gone.

So I don't think this house is the same as the original one, it's just the same location.

When you first looked at the room marker, one of the buttons on my clothes was about to fall off.

Because I also think the sign is a little special and a little curious, 'Why is it only in this room?',

So I also calculated it, and deliberately dropped the button in this room,

So as soon as I came in, I already noticed that the button was missing.

At that time, I suspected that the floor was moving, but later I found that the sign on the wall was also missing, indicating that the wall was also moving.

Later, I combined what Ouyang heard just now, and what Xiao Liu felt,

Basically, it can be concluded that this room must have moved as a whole.

I had been thinking about how this stone house could move, but then I understood when I thought about the sound of water that Ouyang heard.

It just happened that there was such a heavy rainstorm today, and this rainstorm is its power switch, and this rain is the key. ”

"Amazing, amazing, you're a god. Professor, if you have offended a lot before, please Haihan, you have a lot, I Zhang Yi solemnly apologize to you. Zhang Yi also praised again and again,

Thinking of the previous unreasonableness, he was even more remorseful, so he gave up his hand to the old professor.

Listening to what the old professor said, everyone instantly understood,

If he hadn't been there this time, they wouldn't have known when they would have thought of it, and it is estimated that by the time they came up with it, everyone would have starved to death.

The old professor hurriedly helped Zhang Yi and said: "Team Zhang, you are polite, I understand your mood at the time, don't mind too much, fortunately your gun didn't go off, otherwise my old man wouldn't be able to tell you a story, haha." ”

"Haha!" everyone laughed along, and the atmosphere inside was much lighter.
