After Zhang Gong scanned the vicinity, it was found that there were two stones on the ground more than three meters in front, and there were two small spaces under the stones, and it was very likely that the mechanism was located under these two stones. After Zhang Gong communicated this discovery to Professor Chen, the two of them stood silently on top of the stone.

However, the result was that there was no movement of the mountain as they imagined, and there was no passage.

Zhang Gong said discouragedly: "Lao Chen, it seems that this is not the way we go out, let's try something else again." ”

"Don't give up in a hurry, let's pick up the two stones below and then talk about it, I don't think it's accidental, otherwise why is it empty underneath?"

After the efforts of the two of them, the two stones were quickly lifted. After lifting the stone above, the two of them realized that the bottom was not flat, but filled with gravel. After clearing the rubble, two raised stones appeared in front of their eyes.

"Lao Zhang, the stone in this is simple and messy, it should be the back road left by the craftsmen for themselves, so the craftsmanship is not exquisite, let's try it now?"

After trying again, sure enough, there was movement from the place where Zhu Gong had just hit: after the entire wall moved again, the first thing that caught my eye was the time and mark that Ma Kai had written on the wall, and they came out again.

After shaking hands vigorously with Zhu Gong, Professor Chen said: "Lao Zhang, you mark this place, behind this is the space we entered in front, and behind it is the space where we were just now, the mechanism switching here is very interesting, true and false, we should still look for the answer in the space in front, there must be more such organs in front." ”

"Well, but I told you before we got into the first space, and the first time we walked last night, it was all down, so I think we're going to start scanning from the entrance, and I think the problem might be where we just turned in."

"Agree with this, you do a detailed scan with Ma Kai, don't Ma Daha! I've marked all the hidden spaces and sizes in this space, and I think the answer must be here. ”

In nearly two hours of scanning, Zhang Gong and Ma Kai drew the results of the detection in this area.

After reading it carefully, Professor Chen said: "Lao Zhang, let's try these two places, since these two places have been found to exist in a small underground space, they may be where the organ is located, try it." ”

The two took the lead and walked to the front of the line, and when they arrived at the place where Zhang Gong made the mark, Professor Chen stomped down vigorously on the side of the camouflaged steps, and something unexpected happened: in a sound of "bang-la-la", an entrance slowly opened from the original flat ground in front of them. Professor Chen walked to the entrance and felt the sound of air currents.

There is an air current, which means that there is a connection between this and the outside, and it may be that this is one of the back roads left for those craftsmen for themselves, after all, they all know that they will not escape death if they are requisitioned to build a luxurious tomb. Looking at this new passage, Zhang Gong said: "Lao Chen, this should be the retreat that the craftsmen secretly prepared for their escape, and now the airflow here is obvious, indicating that it is connected to the outside, there will be this here, and there should be other places, after all, they don't know where they will be locked up after the project, where they will be slaughtered, from the space just now and here have found a means of escape, maybe more similar will be found here, so it can be judged that the owner of this tomb is a more murderous and untrustworthy person." ”

"When building the tomb, I did find a lot of passages prepared by craftsmen for their own escape, but they were all one or two, and there would be no more than one passage, now I am curious, generally speaking, craftsmen will not understand the mechanism when they are working, and the only person who understands the mechanism can only be the designer or participant, what does the situation here mean now?"

"This shows that the people involved in the design or supervision knew that they would not escape death, so they secretly instructed the craftsmen to divide the mechanism in two, so that the passage that could only enter but not exit was changed to a state that could be opened freely."

"Yes, I think so too, there shouldn't be many craftsmen who know the mechanism and can do tricks, plus the local environmental restrictions, if you can secretly modify the mechanism, it means that you have the cooperation of the supervisor; Now it seems that this is really unusual, don't you think the Ecstasy Array here is enough for us to drink a pot? One can imagine how big this tomb will be. ”

"The size of the tomb is indeed related to the arrangement of the mechanism, but it is not absolute; Generally, the passage used for escape will avoid the main passage, and will be selected at the bottom or top, so we can go down from here to see, and try to detect from here, and there can be a shortcut to the top. ”

"In this way, you probe first, I think there should still be an article to do here, why can't we find the passage we walked for the first time?"

"Don't worry about your first time, now that you can't find the channel that disappeared, let's face up to the status quo and save the country."

"I think we're missing something, there's no reason we can't find that passage, okay, let's not dwell on that, you can go down here and take a look."

Go down and see, this is not easy, because this passage is different from other places, there are no steps, not to mention, and it is very small, it is impossible to stand and walk, you can only crawl on your waist, just for this, you can be sure that this is the escape door prepared by those craftsmen for themselves.

Zhang Gong took out a bundle of ropes from his backpack, tied one end to his waist, and then handed over all the remaining ropes to Professor Chen, and silently looked at Professor Chen with his eyes, and then got into the hole that the craftsmen used to escape.

As the rope became longer and longer, Professor Chen's heart was raised higher and higher, and more than 20 minutes had passed, and Zhang Gong had not spoken, except that the pull of the rope still existed, Zhang Gong was like disappearing, and there was no news. With his trust in Zhang Gong, Professor Chen was still unfazed on the surface except for silently repeating "Lao Zhang, you must come back well".

Sure enough, another 15 minutes passed, and the walkie-talkie rang: "Lao Chen, I have found that there is a fork here, in addition to continuing down, there is a passage that is upward, and it is very wide, I am going to go up and take a look now." ”

"Are you sure? The rope is still more than 20 meters away. ”

"I guess it's not that long, now the light is shining and you can see the end, but I don't know where the end is going."

"You wait, I'll go over now, don't rush in!"

After speaking, Professor Chen put the rope at the end, found a strong raised stone on the mountain, tied it up, rearranged the materials, and climbed into the passage.
