Xiao Qin is a master of tracking. Her purpose in stepping forward is naturally to find clues to determine which path Zhao Ying and others have taken.

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

"These passages can be moved, and the traces they walked through may be wiped off by the moving stone wall." Xiao Qin said.

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

"The passage may have other changes," said Huang Hailin. "The stone walls on all sides may move up and down and left and right."

Xiao Qin looked at Huang Hailin in confusion, "What is the purpose of their creation of such a mechanism?"

Huang Hailin thought for a while and said, "This kind of mechanism has many uses. The biggest possibility is two. One is to isolate the people who may follow you from behind the sacrificial team through the movement of the stone wall. The other is to trap those who do not know the correct route of travel."

When everyone heard this, they looked at each other. Of course, everyone didn't know the correct route. If they didn't know the correct route, the consequence of breaking in was to be trapped in this maze.

Huang Hailin also said, "I have seen similar mechanisms before, in a large tomb of the Qin Dynasty. The Qin and Han dynasties advocated grand funerals, and the tomb protection mechanism is the most exquisite. However, compared with the mechanisms here, that mechanism is very simple. This mechanism has a great feature. The mechanism itself does not have the ability to kill. After trapping the person who is in trouble, the agency will force the person who is in trouble into another fatal mechanism."

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

"The purpose is to ensure that the intruders can operate normally," Huang Hailin explained. "This kind of intruders needs to move up and down, left and right. If the intruders die inside, the corpse and personal belongings will be stuck in the middle of the stone wall, hindering the re-operation of the intruders. Therefore, after the intruders trap the intruders, they will force them into a relatively independent space and let the intruders die there."

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

"Yes, but it's not a single garbage dump, but a slaughterhouse and garbage dump. Those who enter the market are killed or starved to death there." Huang Hailin nodded.

Wang Xinran interrupted, "Why can't I be trapped and sent there again after I was sent to you?"

Huang Hailin said, "Have you ever played the puzzle game? The nature of the puzzle game here is similar to that of the puzzle game. Every movement of the stone wall will have a chain reaction, which is what we often say that one moves the whole body. 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 intruders, the mechanism will force them into the deadly mechanism as soon as possible while operating."

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

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

Huang Hailin's analysis is based on the situation where dust is attached to the stone walls on all sides of the main channel. Some of the stone walls in front are dusty, while others are free of dust. According to the distribution of the dust, it may be possible to infer the movement of the stone wall when the mechanism is started.

Xiao Qin reminded on the side, "Where you outside the copper pillar, you need three people to stand on the same stairs to make the copper pillar turn. After the copper pillar turns, we went in four people, and then the copper pillar began to rotate on its own."

Huang Hailin was thinking anxiously and did not respond. Wang Xinran said later, "What do you mean is that the sacrifices here are not large-scale? There will not be many people coming in?"

"Yes," Xiao Qin nodded, "There may be only three people. There happens to be three passages here. Is there such a possibility that these three passages require three people to walk separately to pass through safely?"

When everyone was talking, Wu Zhongyuan didn't say anything. At this moment, he finally couldn't hold back, "I have one..."

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

"It may also be that the individual things inside are not very large, they don't eat a lot, and the offerings were taken in by three people." Xiao Qin also felt that her inference lacked enough basis, and after saying that, she added, "I'm just a guess, for your reference only."

After Xiao Qin finished speaking, Wu Zhongyuan wanted to speak again, but Wang Xinran interrupted him again and said to Xiao Qin, "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 and signaled everyone not to speak. When he was concentrating on his mind, someone was very distracted from speaking.

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

Wu Zhongyuan couldn't hold it in anymore, and didn't care about that much, "I have a question."

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

"How did the mechanisms in these channels trigger?" Wu Zhongyuan asked.

Only Huang Hailin can answer this question. Although he was a little upset when Wu Zhongyuan spoke to disturb him, Huang Hailin still answered the question, "Gratility."

"Will the mechanism not trigger if gravity is not sensed?" Wu Zhongyuan asked again.

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

"Did you forget that we still have a bird?" Wu Zhongyuan pointed at the little black ghost on Xiao Qin's shoulder.

As soon as Wu Zhongyuan said this, everyone was stunned. They had been worried about how to pass the passage before, but they forgot that there was a starling on Xiao Qin's shoulder, and even Xiao Qin himself forgot.

"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 he interrupted Wu Zhongyuan repeatedly, "It has been silent, and we have all forgotten it."

Huang Hailin was also a little embarrassed, "Yes, sometimes there is still something to make a difference, otherwise it will be easily forgotten."

Yang Yi smiled and said, "The consequence of making trouble is to be sent out to die."

While everyone was joking, Xiao Qin took out a headscarf and put it on the head of the starling brother. The headscarf should be tailor-made for the starling brother, and several small ropes connected to the small camera device.

After putting on the hood, Xiao Qinchong pointed to the passageway and said, "Go."

It can be seen that the little nigger is not willing to leave his master, but it still executes the order and flaps his wings and flies towards the passage directly in front.

After the little nigger flew away, Xiao Qin immediately started to count the timing. Although the little nigger could speak, he could not make complicated descriptions. She needed to estimate the length of the channel based on the time when the little nigger left.

Since there is no internet underground, the small camera device on the little black ghost's head cannot transmit back the instant image. The situation in the channel can only be seen when it comes back.

A few dozen seconds later, the little black ghost came back. Seeing that the little black ghost looked normal, Xiao Qin raised her hand and the little black ghost flew into the right passage again.

It took dozens of seconds to go back and forth, and the last one checked the left channel, which was also dozens of seconds. However, this time, the little nigger seemed very nervous. The nervousness of birds was mainly manifested in panic in their eyes, and the feathers would stand fluffy and erect.

Xiao Qin took off the small camera device on the little black ghost's head and took out the mobile phone card to check it. The first thing that was displayed was the scene of the middle channel. The length of the middle channel was about fifty meters. The four walls of the channel were not flat. There were sunkens in some places, and dust was not available in every location.

At the end of the middle passage is a stone wall, with no exit or stone door.

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