Zhu Gong was not good at the agency itself, so he asked at a loss: "Lao Zhang, since you know that they are on the other side, how can you help them out?" ”

"Lao Zhu, you go up again, pay attention to the details under your feet, there will definitely be a discovery, I judge that the trigger point of this mechanism should be more than 3 meters away, otherwise the movement of the mechanism will definitely be known to Lao Chen, so that he can walk into that bureau unconsciously, and the movement of the channel switch is very small, and it is not in the line of sight."

"Which way did you go when you and Lao Chen came down the first time?"

"It should be the way Lao Chen entered! Because we made a mark after walking for 15 minutes, the speed of walking was slow at that time, and with the speed we had just had, we should have arrived at that place a long time ago, but no, so it means that the road we are walking now is not the first time that Lao Chen and I have walked. ”

"So how did you get out? Don't have paresthesias? ”

"By the way, if you feel abnormal, you just feel that it is very cold, and now it is not so cold here, how did you get out, I didn't feel anything abnormal, so it came out naturally."

"So the mechanism is in there?"

"It's possible," Zhang Gong seemed to remember something, his expression changed, he patted his thigh and said, "That's not right!" There is a situation I want to ask Lao Chen. ”

After speaking, Zhang Gong used the walkie-talkie to say to Professor Chen: "Old Chen, what is the situation there?" ”

"Outside of the circle, nothing else is unusual."

"Did you notice the marks we made the first time we came down?"

"No, so I'm wondering if I'm going the wrong way."

Zhang Gong seemed to be sure of what he had just thought, so he continued to ask, "Do you think it's cold over there?" ”

"Cold? You mean it was especially cold when we first came down, right? I don't feel cold now, but it's still a little hot after walking around. ”

"Understood, you take a few steps to the side or a few steps back, and I'll try to find a mechanism to let you out now."

After speaking, Zhang Gong said to Zhu Gong: "Old Zhu, now that the situation is complicated, there may not only be a matter of two roads in front of us, there may be many. ”

"You mean that Lao Chen's current journey is not your first time?"

"Yes, he didn't find any signs to make, and it's not cold here, just by rushing these two points, I can be sure that these two passages are not the one that Lao Chen and I walked for the first time."

"Don't discuss this yet, find an agency to release them first."

After they walked up a few meters carefully, they really found something strange. The imager in Zhu Gong's hand showed that the steps in front of him were not directly carved into the mountain, but that six steps were placed on an object and connected to the space where Professor Chen was trapped through a small passage.

Zhu Gong didn't understand what this meant, so he brought the imager to Zhang Gong's eyes and asked, "Lao Zhang, come and see, what does this mean?" ”

Zhang Gong carefully looked at the few pictures that had just been saved on the imager, and jumped on the steps above, and after he marked these stone slabs with chalk, he said: "This should be a gravity mechanism, Lao Chen's four people with him must be heavier than us, and they bring more materials, so when we walk on this, the mechanism is triggered, we should only need to squeeze a few more people on this now, and the mechanism can be repeated again, so that Lao Chen can come out." ”

"Why are you sure it's a gravity-type trap?"

"This is also a means for the ancients to prevent tomb robbery, which is not uncommon for mounds; In the past, many times the tomb robbers carried a lot of equipment, such a mechanism design is to do selective triggering through weight, the inside is actually like a seesaw, the opposite mechanism is equivalent to a fat man sitting on the other end of the seesaw, this head can not break the pattern by one or two children, only continue to increase the weight to break the seesaw pattern, so I guess that as long as we generate enough pressure on these 6 steps again, then the passage below will be triggered again; In this way, Lao Zhu, you go down the stairs and pay attention to the changes, I think a few of us will trigger the mechanism after squeezing on it. ”

"Okay, I'll also remind Lao Chen and let them pay attention too."

After speaking, Zhang Gong squeezed onto the narrow steps with eight other people. The result was really the same as Zhang Gong's analysis, Zhu Gong watched a wall below be opened in a fan shape. When the wall is opened, the existing passage is completely obscured, and if you don't pay attention to it, you won't notice the gap above, and you won't notice the change of the steps under your feet, because the new steps look like the rest of the place, all the way down, and there is no difference at all.

Zhu Gong was excitedly about to shout inside, and Professor Chen and his party walked out of it in order.

Seeing Professor Chen's haggard face, Zhang Gong stepped forward to help him and said, "Old Chen, don't say anything first, let's go up and talk about it." ”

In the eyes of everyone, Professor Chen sat on the steps in the middle of the Hades Temple, took a sip of water, and said, "Lao Zhang, the passage below here is complicated, and it is full of ecstasy arrays below. ”

"How?"

"I think now, that is, you continue to go down, the final result should also be to the space we go around, or another same space, anyway, we won't be able to go directly to where we want to go, the real fans below should not be just these, when I found that the walkie-talkie failed, I used the compass to try to identify the direction, but no matter how to turn the direction, the pointer pointed to the middle, at that time my judgment was that there was either a natural magnetic ore in the mountain interfering, or someone buried a large magnet in the middle."

"However, according to the records of the "Ancient Mine Record", the discovery of magnets was in the Warring States Period, and the general's tomb here is from the early Eastern Han Dynasty, and the time difference is more than 100 years.

"No, Lao Zhang, think about it, when I went down with you for the first time, in addition to what you said was particularly cold, we also made a mark, obviously, the passage I went down for the second time was not, and your tone on the walkie-talkie told me that the passage you took was definitely not, that is to say, there is another channel, now no matter whether it is three passages or five, which one is true, this is the first problem we need to solve."

"That's it, Lao Chen, go to bed first, replenish your physical strength, tomorrow we will slowly probe below, my intuition tells me that the cold one is right."

"If the cold passage is right, then it is also said that the past is a good thing for the storage of corpses; Okay, that's it for now, let's sleep, there are a few police comrades who are working hard here, you are responsible for guarding hard, and no one is allowed to enter. ”
