"Hello, everyone. Yanshi mountain is ahead."

The beautiful female tour guide transmits the sweet voice to every tourist through wireless connection.

"Why is it called Yanshi mountain? It's because the site of mechanical civilization was found here. According to the records of Yanshi, the first robot made in ancient times is written in plaintext

The female guide pointed out the window of Yanshi mountain and introduced: "Yanshi mountain is three thousand meters high. There is no grass on the mountain. It looks like an iron mountain from a distance. Therefore, it is also called iron mountain. The site of ancient mechanical civilization is inside Yanshi mountain, where the architectural structure is very complex, like a labyrinth. "

"Because of the special structure of Yanshi mountain, it strongly interferes with the wireless communication. We must follow the planned route to avoid getting lost. Every year, people go missing at the site. It's fun to explore ancient civilization sites, but there's no need to take risks... "

LAN Tianshou and Bai Yunfeng all listened. If there had not been Gao Xuan, they would have been teasing the female tour guide.

Now, they don't have the guts. In addition, the female tour guide often looks happy, and she can't see anyone else in her eyes.

Including other women in the bus, they always try their best to see Gao Xuan. Even those with male companions are hard to be curious and like.

Gao Xuan was wearing sunglasses, and no one could see that his eyes were closed. I just think the boy is too handsome.

For ordinary people, Gao Xuan's handsome is too dazzling. I dare not look directly at it, but I can't help looking at it.

Not only women, but also men.

Compared with the historical sites of Yanshi, people think that Gaoxuan is obviously more beautiful and has more ornamental value.

When a group of people entered the ruins of Yanshi, they all consciously followed them.

The female tour guide stood beside Gao Xuan enthusiastically and explained to him.

"As we all know, the most important metal titanium steel for mankind now is to improve the metal formula obtained from the site of mechanical civilization The site of mechanical civilization is like a treasure, which is of great value to us human beings.... "

The internal structure of Yanshi ruins is like a huge industrial base that has been eliminated. There are steel everywhere. There are some old machines that don't know their uses. Their shapes are strange, and they have the rigor of industry.

Many tourists don't know what to read, most of them are just watching. Take a picture in front of the strange machine, even if it's done.

There are also some people who want to take a chance and look around in the hope of finding something good.

Every few years, tourists will find the special items left by the ancient mechanical civilization and make a fortune.

Although the odds are very low, everyone wants to try their luck. This is also the most attractive place of Yanshi ruins.

Now the virtual reality technology is very mature, and the virtual world built by designers is much more wonderful than the real world.

Come to the field travel, many people will feel bored.

This gimmick of Yanshi remains can't be experienced in the virtual world.

A group of people turned around a little, and unanimously asked the guide to take them to the depth of Yanshi ruins to try their luck.

People took the ancient mechanical lift to the bottom of Yanshi ruins. It's 20000 meters from the ground. The ancient mechanical lift glides very fast, with violent fluctuations, which is just like an exciting roller coaster

when you get off the roller coaster, most of the tourists don't look very good.

LAN Tianshou and they arrived as if nothing had happened. The members of the sword team are weaker than Gao Xuan, but they are much stronger than ordinary people.

The tour guide is also a little ugly, but she is still very professional, guiding tourists to adjust their bodies and dress well.

Twenty thousand meters underground, the temperature is more than 20 degrees below zero, very cold. There are not many lighting sources on this floor, and the environment is cold and dark, which is quite depressing.

The tour guide repeatedly told people not to run around. It's in the lighting area. Assemble in two hours.

After explaining these, the female guide found Gao Xuan attentively: "I am very familiar with this place, I will show you around."

She also said in a mysterious low voice: "this place has been explored countless times by the authorities, and it is impossible to find the leak. Those machines are all imitations.

"But there are still some interesting things at the bottom. It's like a mechanical war puppet. It's all repaired later. It's still very playable... "

The female tour guide is also too fond of Gao Xuan's appearance, which is the only way to tell the truth about the ruins of Yanshi.

"Thank you. We can just walk around by ourselves."

Gao Xuan declined the kindness of the female tour guide. He didn't need to be followed.

The tour guide was very disappointed, and she couldn't follow Gao Xuan hard, so she could only tell him in a soft voice: "although the ruins have been excavated, this place is very big, so it's easy to get lost. It's harder to get in touch without a wireless signal. You've all signed safety contracts. If there's an accident, there won't be search and rescue assistance... "

"I know. Don't worry. "

Gao Xuan waved his hand with a smile and took Yun Qingshang to the deep of the passage.

The female tour guide looks worried, but she should have said it all. Gao Xuan insists on going deep into her.The underground remains of Yanshi are very large, only one tenth of which are open to the public, and some modern supporting facilities have been built. For example, lighting, wireless signal transfer station and so on.

The undeveloped relic area has nothing but the empty relic itself. People get lost in it, and there's no search and rescue help, so it's easy to die in it.

After waiting for two hours, all the others came back, except Gao Xuan and Yun Qingshang.

The tour guide said, "we didn't wait for her to come back."

When a group of women didn't come back, they didn't know. There were several men who were obviously schadenfreuding.

Growing up like Gao Xuan, there must be countless men envious.

LAN Tianshou, Bai Yunfeng and others sneer. How can Gao Xuan have an accident in such a place.

He said to the guide, "don't wait for Gao Xuan. He told me in advance that he would stay at the ruins for a few days. "

Gao Xuan did say it to him in advance and asked him to go back and tell coach Ji Xiuying.

Although the female guide wants to continue to wait for Gao Xuan, but LAN Tianshou has said so, she is not good to delay everyone's time. I can only leave with some regret and uneasiness.

This meeting Gao Xuan has already taken the cloud clear clothes to the deep layer of the ruins.

There are no lights, no modern equipment. It's just endless darkness and cold.

The metal walls and floors of Yanshi ruins are full of traces of violent exploration.

It can be seen that in the past few thousand years, the ruins of Yanshi have been explored and excavated many times. The traces of all kinds of destruction are different from the old and the new, with obvious time intervals.

The ruins of Yanshi are all metal structures, which have a very strong shielding effect on spiritual power.

Gao Xuan's spiritual power can not cover the ruins of Yanshi. Especially in the deep position, the heavy metal structure limits the spiritual power roaming.

Gao Xuan is very satisfied with this. He needs such an environment. Hide in a corner for a few days, and no one will find him.

On the other hand, he had an inexplicable sense of familiarity with the ruins of Yanshi. It should be because of the mechanical war cicada.

"Maybe we can find something here..."

Gao Xuan followed the subtle familiar feeling and wandered in the deep layer of the ruins.

He soon found out the problem. The rooms in the deep core area of the ruins are very regular. Each room is a standard cube, and nine cubes on each floor are arranged in a nine palace grid.

Such a room has a total of three floors, forming a huge third-order cube.

Twenty seven cube rooms were also seriously damaged. The roof, four walls and the ground were all dug out with big holes, which also made the twenty-seven rooms connected with each other.

Obviously, there are many smart people who can see that there is something wrong with this huge magic square.

The only difference is the spherical central control on the wall.

The basketball sized iron ball is engraved with strange words of mechanical civilization. Half of the iron ball is embedded in the wall, and one is exposed outside. Adjust the iron ball to center the text above.

There are 96 characters and 27 rooms on the iron ball, which can be combined into a password by adjusting in different order.

Gao Xuan made clear the cube room structure, and immediately understood how to use the cube.

The six winged cicada chirped, and a group of complex codes appeared in his mind immediately.

Gao Xuan made a simple calculation. Ninety six words and twenty-seven rooms were randomly combined. The number of the combination was terrible. No wonder no one has been able to crack it for thousands of years.

Without the memory left by the cicada, he could not solve the code of the cube room.

Gao Xuan enters the room one by one in order to lock the password. In some rooms, the iron ball like code locks have been broken, and some code iron balls have even been taken away.

Fortunately, he can leave the mark of spiritual power through mechanical warfare cicada, replacing the iron ball password.

In fact, the key is not the iron ball password lock, but the spiritual power mark left when unlocking. It must accord with the spiritual fluctuation frequency of mechanical civilization.

With this design, other civilizations can't crack the cube through exhaustive method.

Gao Xuan is very curious about this. Mechanical civilization has designed such complicated protection measures. What will be in the cube?

He is also a little worried about whether the destructive exploration of the cube by human beings will destroy the secret of the cube?

All room code is right, Gao Xuan sensed source force deep sea suddenly concussion. It's like a huge thing coming out of the source sea.

After waiting for more than ten seconds, the cube room boomed.

The voice was deep, thick and dull, just like an old machine moving slowly.

Kara Kara's voice seems to be stumbling and may stop at any time.

Such a violent shock made the whole Yanshi ruins vibrate violently. People in the ruins of Yanshi thought there was an earthquake. Many people screamed and ran around in panic.Female tour guides, they are still out of the ruins of Yanshi, have not boarded the car, are also scared. Because the whole Yanshi mountain is shaking.

LAN Tianshou, Bai Yunfeng and others are also uneasy and don't know what happened.

At the moment, Jin Guangshan in the ruins of Yanshi first looks puzzled, and then realizes that the change comes from the depth of the ruins. It is clear that there is an important organ in the ruins of Yanshi that has been activated!

Jin Guang is chasing Gao Xuan. He wanted to find a chance to solve Gao Xuan, but he didn't expect to encounter such a thing. He couldn't help but be overjoyed: "there is such a good thing!"
