When they all came out of the cloth, they found that the lanterns had strangely all gone out, as if they had been quietly lit. Zhang Gong walked to a lantern and touched it, the temperature was still there, and there was still oil in it, it seemed that the lantern had just been blown out.

Now Lao Zhang was more bottom-up, and said to Professor Chen: "It seems that in addition to the inside being connected to the outside, the passage will be very complicated, and it may even be the same as the Ranzhuang tunnel war, where every household may be connected." ”

"If that's the case, then it's a huge labyrinth, one ring after another."

"Well, we don't seem to be able to use instruments this time, so we can only rely on the feelings of a few of our old guys."

After a few people returned to the hotel, they held a meeting overnight, and decided to divide the work in the peerless town, and Professor Chen, Zhang Gong and Zheng Suo led people into the passage under the cloth, and decided not to move on that shift at night, and then Ma Kai and Chen Zhijun continued to shoot the details, and the rest was left to Zhu Gong and others.

Regarding the three waterholes, Shao Bin was unable to enter the water himself because his feet were scratched, and through the exploration of several other team members, he finally figured out the situation inside: the bottom of the waterhole is intricate, in fact, the final result is the same, it is also two different burial chambers, but there is nothing in there except for the empty coffin. And down the water inlet, they dived to a depth of more than 50 meters, but they still did not see the bottom, and the natural formation of the pool was bottomless.

Early the next morning, after Situ Fang whispered to Shao Bin, he followed the team into the town.

With yesterday's preliminary discovery, Professor Chen and the others ran directly to the cloth. When he got there, Zhang Gong pushed open the shelves again, opened the secret passage, and several people went inside.

In order to verify his judgment, Zhang Gong carefully searched inside with a flashlight after entering, and when he approached the corner, he found the secret door he guessed, which was retracted to the top of their heads.

The ecstatic Zhang Gong continued to carefully observe every detail on the wall with a flashlight, and finally found a square wooden block with a gap on the side of a pillar.

Proving that the first judgment was correct, Zhang Gong walked ahead and walked down the passage. He took a few dozen steps and stopped, re-searching for the passage he had analyzed.

But he searched for a long time and didn't find it, whether he was going forward or backward, he didn't find the passage he analyzed.

"Lao Zhang, don't worry, I think your thinking is right, but you may have overlooked something."

"How?"

"Don't you see that there isn't that much air flow here now? I paid special attention when I came in, the strong wind that had been blowing all night was now light, almost a breeze. ”

"That means it's still connected to the outside, right? The footsteps were clear yesterday, and they wouldn't be too far away from me, and if they went any further, the altitude would go down, almost below the surface of the lake, and there would be no passage to the outside. ”

"Since the idea is right, then follow the airflow, when you feel the demarcation point of the airflow, then the problem must be there."

"Yes, if this passage is always going to the depths, then there will be no air circulation, and now the circulating air needs to be supported by another channel, and if you follow the air flow, you will definitely find a fork."

While listening to Zheng Suo for a long time, he interrupted the two of them and said to Zhang Gong: "I think your thinking is confused, there is no point in us going along the air, and finding it is nothing more than going out, in that case, what is our purpose?" ”

"It's not about finding a way to the outside, it's about where there should be another way."

"Other passages? It's nothing more than a continuation of the down, a path to the outside, and what else? ”

"I think there's going to be a hidden passage in that place."

"How do you switch between them?"

"For example, there is a T-shaped road ahead, but this is not what we need, then there may be a mechanism similar to a train track trigger at the T-shaped intersection to switch the route here."

"So why not switch there? I think you're mistaken here. ”

"Yes, why ignore this, there may have always existed, the channel switching can be completed in advance, it can also be carried out there, if the channel can be switched in advance, it is much simpler for the design, so, Lao Chen, let's use the 3D imager, otherwise it is really easy to miss too many details."

Professor Chen was reminded by Zheng Suo, and also realized the misunderstanding of thinking, so he said approvingly: "I agree with Zheng Suo's statement, we have indeed entered a misunderstanding, and now we still need to use scientific and technological means to move forward, so let's work hard to get the 3D imager." ”

After speaking, they all retreated to the street, Professor Chen looked at Situ Fang and nodded slightly, and Situ Fang was ordered to run away, and soon disappeared from the sight of several people.

Zhang Gong took off a lantern from the door of the shop and said to Professor Chen: "Old Chen, look at this lantern, there is still half of the oil in it, and the wick is also good. ”

Professor Chen took the lantern and looked at it and said: "It's also a Lian family, after the purpose of introducing us to the cloth shop is achieved, naturally these lanterns no longer need to cost more fuel, so they quietly snuff them out, this one action has two meanings, one is to tell us that our every move is under their surveillance, they can make moves against us at any time, and the other shows that they are very thrifty." ”

"By the way, what about the lights in the store? We didn't touch it when we left at night, and it was extinguished when we came just now. ”

"I guess they killed us after we left."

"Oh, so they really know how to save energy."

"This is shark oil, which is very precious, and it should be bought from abroad, and there is no such thing sold in China."

"Not like that in the Mausoleum of Qin Shi Huang?"

"No, it's made of whale brain oil, a candle can be burned for hundreds of years, if it is made big enough, it can be burned for thousands of years, it is a rare thing, I was reminded by Zheng Suoyi just now, I think we are a little overconfident, maybe there is a mechanism from the bend inside, but we trust intuition too much."

"Yes, this tomb is different from other places, it has always been in a state of technological update and has been maintained, so the complexity in it will be higher than other places, in addition to fighting wits and courage with the ancients, we also need to PK with modern technology."

"Well, let's use high technology to try to decipher the secrets here."

Zheng saw that the two of them had already walked out of the misunderstanding, so he reminded again: "Since our every move is under their control, let's also be on guard, no matter where we go, we will bring the police, in case they misinterpret us and make wrong decisions about us, we need to have enough defense capabilities." ”

"Agreed!"
