Xiao Qin is a master of tracking, and her purpose in stepping forward is naturally to find clues, so as to determine which way Zhao Ying and the others went.

But the observation made Xiao Qin very puzzled, because there were no footprints left on the left and right forks, and there were no footprints on the passage ahead.

"These passages are movable, and the traces of their walk may have been erased by the moving stone walls. Xiao Qin said.

Wang Xinran was not surprised by Xiao Qin's observations, and asked Huang Hailin, "What are the consequences of continuing to move forward?"

"There may be other changes to the passage," Mr. Huang said, "and the stone walls on all sides may move up, down, left and right." ”

Xiao Qin looked at Huang Hailin puzzled, "What is the purpose of their creation of this kind of mechanism?"

Huang Hailin thought for a moment and said, "This kind of mechanism has many uses, and the biggest one is that through the movement of the stone wall, the people who may follow in are isolated behind the sacrificial procession. The second is to trap trespassers who do not know the correct route of travel. ”

When everyone heard this, they looked at each other, and the correct route of travel was naturally unknown to everyone, and if they did not know the correct route of travel, the consequence of rashly breaking in was to be trapped and die in this labyrinth.

Huang Hailin said, "I have seen similar mechanisms before, in a large tomb in the Qin Dynasty, the Qin and Han dynasties advocate thick burials, and the tomb protection mechanism is also the most exquisite, but compared with the mechanism here, it is very simple, this kind of mechanism has a great feature, the mechanism itself has no lethal ability, after trapping the trespasser, the mechanism will force the trespasser into another deadly mechanism." ”

"What is the purpose of this design?" Xiao Qin asked again.

"The purpose is to make sure that the mechanism can always be functional," Huang Hailin explained, "This kind of mechanism needs to be moved up and down, left and right, and if the trespasser dies inside, the body and belongings will get stuck in the middle of the stone wall, hindering the operation of the mechanism again, so after trapping the intruder, it will force them into a relatively independent space, and let the intruder die there." ”

After Huang Hailin finished speaking, Xiao Qin answered, "That relatively independent space serves as a garbage dump?"

"Yes, but not a single dump, but a slaughterhouse and dump where trespassers are killed or starved to death. Huang Hailin nodded.

Wang happily interjected, "Why can't it be sent there after being trapped and dying?"

Huang Hailin said, "Have you ever played a jigsaw puzzle? The mechanism here is similar to the nature of a jigsaw puzzle, every movement of the stone wall will have a chain reaction, that is, we often say that the whole body will be moved, if there are multiple intruders, the mechanism will not have enough space to imprison them, in order to ensure the continuous operation of the mechanism, after capturing the trespassers, the mechanism will force them into the deadly mechanism as soon as possible while running. ”

"Can you analyze the internal composition and operating principle of this organ?" Wang Xinran asked again.

Huang Hailin shook his head, "It's difficult, I'll try it first." ”

Huang Hailin's analysis is based on the dust attached to the stone walls on all sides of the main passage, some of the stone walls in front of it are dusty, some are not, and according to the distribution of dust, it may be possible to infer the movement of the stone walls when the mechanism is activated.

Xiao Qin reminded on the side, "Outside the copper pillar, three people need to stand on the same step to make the copper pillar turn around. After the pillar turned, we got four people in, and then the pillar began to rotate on its own. ”

Huang Hailin was thinking eagerly and didn't answer, Wang Xinran said in the back, "You mean that the sacrifice here is not large-scale, and there won't be many people coming in?"

"Yes," Xiao Qin nodded, "There may only be three people, there happen to be three passages here, is there such a possibility, these three passages need three people to walk separately to pass safely?"

When everyone was talking, Wu Zhongyuan didn't speak, and finally couldn't bear it anymore at this time, "I have a ......"

Before Wu Zhongyuan finished speaking, Wang Xinran raised his hand to interrupt his words, and turned to Xiao Qin and said, "It seems that there is indeed such a possibility, but have you ever thought about it, if it is really what you said, then the possibility of human sacrifice is ruled out, and the three people who went in were all voluntary." ”

"Maybe the things inside are not very large, and there is not a lot of food, and the sacrifice was brought in by three people. Xiao Qin also felt that his inference lacked sufficient basis, and added after speaking, "I'm just guessing, just for your reference." ”

After Xiao Qin finished speaking, Wu Zhongyuan wanted to speak again, but Wang Xinran interrupted him again, and said to Xiao Qin again, "If we go separately, if the mechanism is activated, we will be separated, and the situation will be even more dangerous at that time." ”

After Wang Xinran finished speaking, Huang Hailin waved his hand, signaling everyone not to speak, and someone on the side was very distracted when he was concentrating on thinking.

Wu Zhongyuan wanted to speak again, but Wang Xinran pointed at Huang Hailin and motioned him not to interrupt Huang Hailin's observation and analysis.

Wu Zhongyuan really couldn't hold it back, and he didn't care so much, "I have a question." ”

"What?" Wang Xinran asked in a low voice.

"How are the mechanisms in these passages triggered?" Wu Zhongyuan asked.

This question can only be answered by Huang Hailin, although he was a little upset that Wu Zhongyuan's words disturbed him, Huang Hailin still answered this question, "Gravity." ”

"If you don't sense gravity, won't you trigger the mechanism?" Wu Zhongyuan asked again.

"What do you want to say?" Huang Hailin turned around.

"Have you forgotten that we still have a bird?" Wu Zhongyuan pointed to the little on Xiao Qin's shoulder.

As soon as Wu Zhongyuan said this, everyone was stunned, they had been worrying about how to pass through the passage, but they forgot that Xiao Qin still had a starling on his shoulder, and even Xiao Qin himself had forgotten.

"Can you let it fly in and take a look?" Wu Zhongyuan asked.

"Yes. Xiao Qin nodded.

Wang Xinran also felt embarrassed about the words that had repeatedly interrupted Wu Zhongyuan before, "It has been silent, and we have forgotten about it." ”

Huang Hailin was also a little embarrassed, "Yes, sometimes you have to make some noise, otherwise it will be easy to be forgotten." ”

Yang Yi said with a smile, "The consequence of making a disturbance is to be sent out to die." ”

While everyone was laughing, Xiao Qin took out a headgear and put it on the starling's head, this headgear should be tailor-made for the starling, and several thin rope belts were connected to the small camera device.

After putting on the hood, Xiao Qin pointed to the passage ahead of the starling, "Go." ”

It was obvious that the little was reluctant to leave its master, but it carried out the order anyway, flapping its wings and flying towards the passage directly ahead.

After the little flew away, Xiao Qin immediately started to timer, although the little could speak, but she couldn't make a complicated description, she needed to estimate the length of this passage by the time the little left.

Since there is no internet underground, the small camera on the little's head can't send back real-time images, and the situation in the tunnel can only be seen when it returns.

Dozens of seconds later, the little came back, seeing that the little looked normal, Xiao Qin raised his right finger, and the little flew into the passage on the right side again.

It took dozens of seconds to go back and forth, and the last check was the left passage, which was also dozens of seconds, but this time when I came back, the little looked very nervous, and the nervousness of the birds was mainly manifested in the panic in the eyes, and the feathers would be fluffy and erect.

Xiao Qin took off the small camera device on the little's head, took out his mobile phone card to check, and the first thing he showed was the scene of the middle passage, the length of the middle passage was about fifty meters, the four walls of the passage were not flat, there were depressions in some places, and the dust was not in every position.

At the end of the middle passage is a stone wall with no exit and no stone gate.

The situation of the right passage is similar to that of the middle passage, and there is also a stone wall at the end.

The last thing I looked at was the image of the passage on the left, at first the situation of the passage was not much different from the other two, but this passage had an end, at the end of the passage was a very wide area, about the size of a small auditorium, and inside was a strange and terrifying ghosting scene, behind the hazy Qiongtai Pavilion, there was a row of hanged corpses......
