The speed of the march is slower.

It took them nearly half an hour to reach the end of the hallway, where there was still a door, which opened in a similar way to the previous one, and it was very easy to open it with modern technology.

After the door opened, one of the team members walked in with a light first, followed by two people behind.

But the person in front of him didn't know what this man saw after entering, and he suddenly let out an exclamation.

Professor Chen and the others were in the center of the line, and after they sensed this movement, they were immediately pulled by Ye Wudao and began to retreat.

The exclamation of the first to enter had a terrible consequence.

That is, there was a sudden echo in the unknown space, exactly the same as the sound made by the person, but the ratio of decibels was so high that the reverberation was not much higher, and it directly shocked the person's eardrum and bleed.

Obviously, even if this person is not dead, he is already dead.

Such a sound wave is beyond people's imagination, and the two people in the front were directly deaf, and it was very painful to cover their heads.

However, the three people in front of them were the closest, sharing the most serious attack damage, and the people behind were also forced to cover their ears when they retreated in horror, and insisted on enduring for about ten seconds before they survived the attack of the sound echo.

Silence returned to it.

When Professor Chen and Ye Zhengdao saw this situation, they didn't speak to each other, but just gestured, which made it easy for people to understand.

That is, everyone should not speak loudly, and at the same time, they should wear headphones and communicate with gestures and gestures to avoid echoing as much as possible.

There are lessons from the previous people in the front, and the people in the back of course recognize the horror of the amplified echo, so they put on headphones and masks one after another.

At the same time, the work of pathfinding in front was also handed over to a robot.

It was robot No. 1, and after being dispatched to the facility first, Professor Chen and Ye Wudao were able to see the real-time images transmitted by robot No. 1 through robot No. 2.

I saw that there is a kind of arched circular building style like an echo wall, there are a lot of hideous and terrible stone carvings placed in it, it looks very terrifying at first glance, and the position of each stone sculpture is also different, very regular, and there is a kind of concave wall nearby, the whole looks like a large horn.

I don't know what role this style of architecture plays, but it fully reflects the wisdom of the ancients.

Professor Chan deduced that it might be a facility that could amplify the echo, and the sound wave created was very strong in decibels, as evidenced by the unlucky ghost before.

After Robot 1 entered, it explored inside, but found no mechanism except for the bones of many humans lying on the ground.

The bones of those human beings are all dressed in ancient costumes, some with the style of the Exquisite Country, and some with the style of other small countries in the Western Regions, it seems that some people from some countries in the Western Regions are concentrated here, and some of them died in this echo building, and from the analysis of their deaths, they all killed each other.

After Professor Chen and Ye Wudao analyzed the situation inside, they felt that in addition to the echo, what happened to those people was like a hallucination after being subjected to an image and tearing each other apart, indicating that there was a kind of existence that could cause mental interference to people.

After discussion, Professor Chen and the others made all the preparations, and then they entered the echo building.

They didn't dare to make any noise when they entered, and followed the path of Robot 1 to the center of the building, where there was a huge statue.

However, at the base of the statue, Professor Chen and the others found the mural painted on it.

The mural is also shorter, telling the story of a queen who came here to build the Echo Temple, trying to kill the ghost through the Echo Temple.

However, the ghost can match the ghost on the previous mural, and the queen's costume is also similar to the costume in the little girl Oasis Watch picture in the mural outside, could they be the same person, this queen is the little girl who grows up.

While Professor Chen was researching the murals, Ye Wudao led people to discover a metal door on the left and right sides of the statue.

The door was very airtight, connected to the mechanism, and had to be opened in the right way.

Professor Chen discussed with Ye Wudao and the others that in the case of excluding the use of explosives, the only way to open the two doors was to find the mechanism to open in this hall of sound, otherwise there was no other way.

After searching the Echo Hall for an hour or so, someone stumbled upon a key in the pocket of a skeleton.

If it's like an iron rod with a plum blossom-shaped barb, it looks very beautiful.

With this thing, it was easy to find a plum-shaped hole in the fingertips of the large statue in the middle of the Echo Hall.

Ye Wudao was very stable after inserting the plum blossom-shaped key into the hole, he tried to unscrew it but didn't twist it, so he pushed it up again.

As a result, after pushing upwards, suddenly there was a sound of a mechanism activating from inside the statue.

Immediately after that, a closed door to the left of the statue stone slowly opened, and only a low sound was emitted from the opening, which did not touch the echo in the echo hall.

The door seemed to be out of order after it was halfway open and not fully opened, so Professor Chen sent another robot inside to check on the situation alone.

After the robot entered, it found that it was another corridor, and the corridor was not too long, about twenty meters or so.

Shout!

This time, however, it wasn't so lucky, and the robot went in and touched a gravity-controlled mechanism somewhere on the floor.

After the mechanism was touched, countless crossbow arrows were shot nearby, and when the crossbow arrows were fired, when they encountered air friction, they would suddenly burst into phosphorus fire, just like ghost fire, and at the same time, a kind of fire oil would spread out from some grooves on the ground, and then a raging fire would burn in the corridor.

And the fire was so fierce that suddenly something began to loosen above the head, and then there was a sound like metal rubbing.

Professor Chen's face changed drastically after discovering this anomaly, so he hurriedly stepped back, and at the same time gave Ye Wudao and them an urgent gesture to ask them to think of a way to close the door.

The friction between the metals actually caused a strong noise, which was just enough to trigger the echo in the echo hall, if that case, they were afraid that the people in the hall would be in great trouble.

Ye Wudao couldn't care about the robot trapped inside, so he hurriedly ran over to the statue to reset the state of the key.

When the key is reset, the door on the left slowly closes.

But at the same time as it was closed, there were still reverberations in the array inside, creating a strong echo in the Echo Palace.

But fortunately, the echo was not very violent, everyone wore headphones to isolate it, and the impact was not great, and after the closed door was closed, the sound was completely isolated.

After the gate was closed, the peace in the hall was restored, and everyone couldn't help but breathe a sigh of relief.

Fortunately, there were no more casualties.

Obviously, there is a trap in the door on the left, which is very dangerous, and there is no way to pass through the door on that side, so Professor Chen discussed with Ye Wudao whether to open the door on the left to see the situation.

Ye Wudao felt that they had never seen the temple, but they had found these buildings that were not related to the temple before, and they suspected that the queen had built it, mainly to protect the temple.

Since they have come there, it is always unwilling not to look at it, and the entrance gate of a god saint is also mentioned on the mural outside, which makes everyone's heart itch.

So, after everyone agreed, Ye Wudao walked up to the statue again and pressed down with the plum blossom-shaped key as an attempt.

As expected, after pressing down, the door on the right slowly opened.

It's just that after the door on the right was opened, the corpses of the dead bodies inside were densely packed inside, which once again cast a shadow on the hearts of the expedition members.

The door on the left that was opened earlier had many traps and traps inside, but no dead people's bodies were found inside, but the door on the right was the opposite, and the large number of corpses inside confirmed that it was full of death and killing, which made everyone hesitate to go in and investigate.

Some people have begun to retreat, saying they don't want to investigate further, but some people think that the inside of the door on the right looks scary, but it should be safe.

In the end, it was Ye Wudao who overrode the public opinion and let the two cowards who didn't want to go in anymore stay behind to guard the key mechanism, and he personally led people into the corridor on the right.

This time, he didn't send the robot in to test it, because Ye Wudao based on his exploration experience, he could roughly judge through his intuition that there were not many traps in the door on the right, and the reason why there were so many corpses piled up was that these people were trapped inside, not killed by some traps.

After Ye Wudao took two people and two robots to take the lead in entering, they explored the way in front and asked the robots to clean up the bones in front of them, and sure enough, there was no mechanism that was triggered, and there was no danger.

So, Professor Chen saw that they were still safe in the middle, so he led the people inside.

Soon, the group passed safely through the short corridor, and found a large hall in front of them.

The hall is ornate and majestic, with lifelike statues and some of the trumpet-like measures used in the Hall of Echoes.

Of course, there are also a lot of bones here, which is very infiltrating.

The most important thing is the very center of the main hall, where there are three huge statues, one of which is the statue of the Exquisite Queen.

The other two are more strange, one is an eagle-headed human body, the other is a wolf-headed human body, plus the snake-headed crown worn by the queen, which makes people feel very strange.

However, after Professor Chen saw such a combination of three statues, he felt that this was already related to the Zhending culture, because the three gods believed in the Zhending culture are the characteristics of the combination of the eagle head, the wolf head, and the snake head, but the statues here are carved separately.

It's just that there are still facilities similar to the Echo Hall here, and I'm afraid that there will be no sound here.

Professor Chan cautiously searched for the mechanism again.

However, in the process of searching for the mechanism, several murals in the main hall once again attracted the attention of Professor Chen and Ye Wudao.

The robot also filmed the contents of the murals.

The content of the fresco can be connected to the fresco in the previous building, which tells the story of King Elite who returned to the kingdom after sealing the sacrificial temple and was just in time for the queen to give birth.

As a result, a girl was born, and the king made her a princess.

As a result, after about six years, this little princess behaved differently from ordinary people, she seemed to have two personalities, an angel during the day, a devil at night, and she was able to summon snakes, and was called a snake girl by the Chinese.

One day the king ran out of the door after getting drunk at night, but accidentally broke into the snake formation and was bitten by the snake, although he was treated by the little princess, but he was still seriously injured, and the people of the country were often attacked by snakes and suffered unspeakably, and the little princess was banished by the king because of this incident.

The little princess was very sad when she was banished, but she was reluctant to leave her home too far, so she found a small oasis in the desert and made a home there to live alone, and spent her days with snakes.

After arriving here, part of the hints and metaphors in the mural are revealed, which correspond to the mural of the little girl watching into the distance.

Then, the mural depicts that ten years later, when the little girl is eighteen years old, the little oasis she lives in is about to dry up and be swallowed up by the desert, so she takes several giant pythons in the desert to find a new home.

As a result, the girl inadvertently found the sealed and forgotten sacrificial temple that was mostly buried in the yellow sand, hidden in the desert.

After the girl entered the temple with the help of the serpent, she was lucky enough to encounter the manifestation of the light gate, and she walked to the light gate and looked very holy, just like a god.

Moreover, she was not attacked by any ghosts, and after praying there, the girl entered the gate of light.

A year later, the girl walked out of the Gate of Light, she became different, not only able to command ten thousand snakes, but also possessed special powers, so she left the temple and returned to the Elite Kingdom, where she inherited the throne a month later and became a queen.

The queen then led her soldiers into battle, conquered many nearby tribes, captured many slaves, and then began to secretly build buildings around the temple, making it a forbidden place.

It's just that in the process of expanding the temple, the light gate appeared again, and as a result, many slaves were turned into demons by the ghosts that came out of the light gate and began to kill people like crazy, and then it was the Queen of Absolute who came to suppress it herself, so she killed the ghosts.

After the temple was expanded, the queen ordered a mural of her experiences in half her life, as well as some of the experiences of the previous king.

The contents of the frescoes are no longer there, and there is no record of what happened after that, and it is not known what the queen did afterwards.

At this time, Professor Chen suddenly realized something, and he became nervous. If you want to talk about "Fragmented City" with more like-minded people, pay attention to "excellent reading literature" on WeChat, talk about life, and find confidants~
