After walking around the three doors again, Professor Chen was still a little puzzled by what Zhang Gong had just said, and asked a little suspiciously, "The road is behind the middle door?" ”

Zhang Gong smiled and said, "Well, the passage must be behind the door in the middle!" ”

"So how do you turn it on?"

"It's simple, just change the layout of the wind escape to the sky escape."

When Professor Chen heard this, he understood the key point of the organ, and dared to adjust the formation layout of Qimen Jiu Dun! So he asked tentatively: "Oh, that means that the three doors of opening, resting, and giving birth are not moving, and the layout of the other five doors can be changed?" ”

"Yes, since the current layout is said to be conducive to travel, such a layout is only a day escape in addition to the wind, and these two layouts are open, rest, and give birth, so I guess it must be like this."

"So are you sure about the map?"

"Let's change this Qimen Nine Escapes first, and this should be how it is cracked."

As he spoke, Zhang Gong started to press on the stone bar.

Professor Chen, who was on the side, saw that Zhang Gong was anxious again, and quickly stopped: "Stop!" Since you said that the other two doors are maps, let's make sure and then open this passage, I'm afraid that after opening the passage, the two doors on the side will disappear or be destroyed inexplicably. ”

"Well, let's take a picture of this place first."

Under Zhang Gong's call, all the people gathered around. The taking of pictures, the detection of probing, and the discussion of discussion suddenly became lively.

In a quarter of an hour, all the work was done. Scanned by the imager: there is a large space above the three doors, and there is a deep pit under each door, and behind the middle door is a passage, and nothing else. After Zhang Gong finished drawing the graphics on the left and right doors in his notebook, he said to everyone behind the door on the right: "The details here have been measured and recorded, right?" Okay, I'll talk about the next route; Look here, it looks like an isosceles trapezoid, this should be the way we are going, we should be on the second breaking point on the left side of this trapezoid, the stone layout behind the door on the far left tells me, those numbers are 8, 16, 8, 4, 2, what is the use of these numbers? Don't worry, now let's take a good look at this trapezoid, from the top to the bottom, there is a gap here, we might as well start from this gap, think of it as the first layer of stone behind the door on the far left, then we find the second layer, the third layer, the fourth layer, the fifth layer, the sixth layer, and then jump 2, 4, 8, 16 and 8 layer by layer, okay, what do you see now? ”

After Zhang Gong's chalk drew circles and lines one by one, a clear route came out, which happened to appear on the gap in the middle of the left side of the trapezoid.

Zheng saw Zhang Gong find the answer so quickly, and exclaimed: "I just heard how unfathomable Zhang Gong's level is, and I thought it was an exaggeration at that time, but I really admired it when I saw it today!" ”

Zhang Gong smiled innocently, touched his head and said, "This is also the light of Lao Chen, otherwise how can anyone know about me." ”

Professor Chen saw that the topic had changed a little bit, so he immediately changed the topic and said: "Judging from this diagram, that is to say, after reaching the top, there will be a downward channel, and then almost all the way back and then up, and there are still many places where we may pause." ”

"Yes, I think this diagram is the same as the relay race, it just tells us how to walk this passage, so choose the route, and we need to continue to explore the rest."

"Lao Zhang, if this picture is correct, that is, when we reach the top high, we still have to pass through two platforms, and then go down to five, and it is unknown when we get there, so I think our supplies may not be enough."

"Let's go first, and we'll go back to repair when we have half a day left in the supplies."

"Okay, then open the door, let's speed forward."

Under Zhang Gong's three strokes, the layout of the stone strip behind the middle door was changed, from the wind escape to the sky escape, just after he pressed the last stone strip, in the sound of "boom", the stone strip wall instantly fell into the deep pit underground.

With the opening of the passage, the air environment here seems to have changed slightly, although it is still very dry, but the oxygen content does not feel so low. After Zhang Gong took a few steps inside and took a few good breaths, he said to everyone refreshedly: "The air here is much better now, let's go, Professor Chen said, we will rest when we get to the next platform." ”

Situ Fang walked back to the front of the group, probing and advancing. But after walking for a few minutes, a situation suddenly appeared in front of me: a pile of rocks blocked the front, and the road was blocked. Situ Fang walked up to the rocks, carefully looked at and sniffed the stones, and then retreated into the group and whispered: "The front was blown up, and it has been blown up for a while, it is estimated that it happened shortly after we separated from the grave keeper, and there was a slight vibration at that time. ”

As soon as Professor Chen heard that the rocks in front of him were the result of blasting, and knew that the tomb robbers had run in front of them again, he immediately said with a nervous expression: "Then quickly clean up the rubble, let's go in quickly, don't let them get ahead of them!" ”

"Good! Then you all go back first, so as not to have an accident, and we will do this work!" ”

After saying that, Situ Fang mobilized all the people of the expedition, they unloaded their backpacks, and carried the stones in groups of two. Seeing that there was a lot of gravel, the Fan team soon joined the armed police and special police into the carrying work. In half an hour, the passage was opened.

Professor Chen stood in front of the bombed hole and looked at it, the blasting position was quite accurate, close to the side of the passage, and the hole was perpendicular to another passage, and the distance between the two passages was only less than a meter.

Now that there were grave robbers passing in front of them, they could move forward boldly and confidently, and the group arrived at the next platform in ten minutes or so. As soon as he arrived at this platform, Situ Fang smelled a smell of blood, and he whispered to everyone to turn off the flashlights and headlights, and then communicated the situation to Team Fan. Subsequently, the armed police and special police immediately opened the insurance of all kinds of guns and opened the on-site vigilance.

Situ Fang saw that the armed police were ready, so he scanned the platform with a flashlight, and the first thing he saw was the corpses of two tomb robbers more than a meter away, their bodies seemed to have been scratched by some animal, the flesh and blood were blurred, and there were several deep scratches on their faces, revealing the white bones inside. Situ Fang glanced around again, and after finding nothing abnormal, he conducted a detailed search of the platform with Team Fan and the leader of the armed police.
