Xia Qing asked, and the two of them shook their heads again, looking dazed, like two unresponsive elementary school students.

Xia Qing, www.biquge.info of the pen "Fun" Pavilion, glanced at the two of them, and had to say helplessly: "This is because all the heads on this stone bar are very evenly distributed on the stone bar, and the gap between them is not much different from the space between the heads on other stone bars, so it is difficult for us to distinguish them with the naked eye at first glance." ”

When Gao Chao heard this, he couldn't help but say, "But what does it matter? Even if the distribution is even, what does it have to do with the secret passage we are looking for? ”

The fat man also grinned on the side: "I said Miss Xia, please, you hurry up and say the conclusion, I don't read much, I'm going crazy!" ”

Facing these two men, Xia Qing only sighed and said: "I want to say, if I guess correctly, the heads on the stone strips should be fixed, that is, they can't move left and right like the heads on other stone strips, they are all evenly fixed on the stone bars, there must be a reason for this, and the biggest possibility is that those heads may be the organs of the secret passage." ”

When the fat man heard this, he said, "Then such words are too simple, right?" Whoever counts them one by one, doesn't they know that there is something wrong with the head on this stone bar? If the secret passage mechanism is so easy to find, then it won't be called a mechanism! ”

Xia Qing said helplessly: "Do you have to understand, this is a secret room built nearly 4,000 years ago, how many people at that time knew mathematics?" Not to mention mathematics, even if it is to ask ordinary people to count from one to twenty, I am afraid it is not an easy task. ”

The fat man tilted his head and thought about it, feeling that there seemed to be some truth.

Gao Chao couldn't wait at this time, so he hurriedly said: "Xia Qing, if what you said is right, then let's try it quickly!" ”

Xia Qing nodded, and Gao Chao took action.

In fact, although the stone bar was more than three meters high from the ground, it was not difficult for Gao Chao.

Gao Chao climbed up with his bare hands, and the fat man raised the torch in his hand as high as possible below to illuminate Gao Chao.

Gao Chao grabbed the stones and climbed up, inevitably stepping on some skulls with his feet, he whispered an apology as he climbed, although he was not tired of climbing, but his heart was a little uncomfortable.

In a few moments, Gao Chao climbed to the height of the stone bar, fixed his body, and freed up one hand to move the heads.

As a result, he tried this time, and it was really the same as Xia Qing said, the head was in the left and right directions, and it couldn't move at all, Gao Chao quickly tried a few others, and they were all fixed on the stone bar.

Seeing this, Xia Qing and the fat man cheered happily below.

At this time, Xia Qing thought for a while before saying, "Gao Chao, you try it and see if those heads can be turned." ”

Gao Chao nodded, and then carefully turned one of the heads with his hands, only to find that it was also fixed and could not be rotated at all.

Xia Qing said again: "It seems that it's right, then you have to work hard, hurry up and try them one by one, there should be one that can be turned!" ”

Gao Chao smiled: "Where is the hard work, serve the people!" ”

Then, Gao Chao started from one end, and tried to turn those heads one by one towards the other end, one after another, which could neither move nor turn, just like that, Gao Chao patiently moved his body little by little, and then tried one by one, and at this moment, the fat man and Xia Qing below, both of them also held their breath, I don't know if it will be as Xia Qing said, the mechanism of the secret passage is on top of these heads.

Time passed minute by minute, Gao Chao had already tried most of the heads, he was about to move to the other end of the stone bar, seeing that there were no more heads left in front of him, the three of them couldn't help but get anxious, Xia Qing had even lowered his head, wanting to start smoothing out his train of thought again.

And at this moment, when basically they were not very hopeful, a head in Gao Chao's hand was really turned.

And as he turned the head, he clearly felt a kind of resistance, and he felt that there must be some mechanism connected to the back of the head.

Sure enough, as soon as Gao Chao turned hard, he heard the whole wall start to "bang"

It sounded like a lot of loose wheels were spinning, and then he felt a sudden slip under his feet, and somehow, he fell from a height of more than three meters.

Fortunately, the fat man below was quick-eyed, and rushed up to support Gao Chao in one step, so Gao Chao didn't fall.

But at this moment, the wall of skulls in front of them suddenly changed.

I saw that all the heads on the wall began to turn up inexplicably, making a "bang"

The ringing sound.

The three of them were dumbfounded, this situation is too indescribable, it is difficult to describe it in words, it can only be said that at this moment, in front of them, there are more than 300 people's heads, constantly flipping, and the whole wall, like a huge password wall, as if those human heads, are constantly changing password combinations.

At this moment, the skull code wall suddenly made a muffled sound, and at the same time, the whole wall was like a door, slowly opening to one side, and the whole wall was trembling slightly, but on one side, only a gap was opened, which was not wide or narrow, and the wall suddenly stopped moving outward, and then immediately began to come back, seeing that the gap narrowed, and the door was about to close again.

Seeing this, Gao Chao hurriedly shouted: "Quick! Let's get in! ”

Fortunately, the three of them were not far from that gap, and no one dared to delay at this moment, so the three of them rushed into the pitch-black gap without thinking about it.

Gao Chao was the last to get in, but as soon as he got in, he felt his feet slip, and he fell backwards violently, falling to the ground.

But before he could react, he felt like he was smeared with oil underneath his buttocks, which was extremely slippery, and he didn't know how to slide down.

At this time, it was pitch black in front of him, and he didn't know what happened to the fat man and Xia Qing who came in front of him, whether they had the same experience as him.

In a hurry, Gao Chao wanted to shout, but his ears were full of "boom"

There was a loud noise, like the sound of the operation of the agency's message, and like the sound of the rushing river.

But before he could figure out the situation, his whole body suddenly rose into the air, and there was darkness all around, and he didn't know if he had fallen, or what, in short, his body was already in the air now.

So Gao Chao was so frightened that he screamed.

"Ah......h

But this "ah"

Only half of the words were shouted, he felt that the whole person had fallen into the water, the water around him was extremely cold, and very turbulent, he only felt like he had fallen into a huge washing machine, the whole person rolled around in the water, turned in the dark, up and down, he could only try to hold his breath, desperately swinging his limbs, but it seemed to be useless.

In such a panic, Gao Chao was a little desperate, he felt that he was about to lose his breath, was he going to drown again?

But at this moment of despair, he only felt that his body was light again, as if with a wave of water rising into the air again, and everything in front of him seemed to suddenly have light, but this light was still very dim and vague, he felt that this was some kind of hallucination, how he seemed to fly.

But Gao Chao, who had just felt better, fell deeply into the water again, but this time, he finally did not get the wrong direction, he immediately swung his arms and kicks, and swam quickly towards the water.

When his head resurfaced, he used all his strength to inhale a deep breath of air, and his lungs were once again oxygenated, and the blood quickly transmitted oxygen to his brain, and his brain began to work rapidly again.

Gao Chao breathed the water for a long time, he began to wake up, everything in front of him was no longer blurry, and there was a touch of light, at this moment he looked up sharply, only to find a large, round light source, which was scattering a bright light.
