The bottom of the cliff was dark, and the whole basin was blowing a strong wind from nowhere. The wind direction was strange, and Gu Chuan lowered his head for a short while, and he was blown sand full of hoods.

He flicked his hood, and the sand fell with the wind behind Hatsukumo. Chu Yun felt the pressure on his back, raised his eyes suspiciously, and looked at Gu Chuan in front of him.

The young man was embarrassed, knowing that he had thrown a large piece of sand onto Chu Yun's back. He hurriedly turned his head sideways, looked left and right, and said something else:

"It seems to be getting warmer here."

Only the overall temperature of the Great Wilderness illuminated by moonlight may be similar to the Bailu solar term in Sunset City, which is close to frost, which can be regarded as cold.

Both of them had a sense of discomfort along the way.

"No, it's like, the temperature here is really rising." Chu Yun shook his clothes and stated one by one, "According to my feelings, the temperature in this area is similar to the average temperature in Sunset City, and the further down it goes, the hotter it may become. ”

Hatsuyun was able to accurately describe most of the sensations and changes in her body, and she said that the temperature here did rise, and that was probably the case.

On the great wilderness, there are many rocks. There are several rocks that are tilted and support each other, just forming a sheltered space from the wind. The two walked in. Gu Chuan wanted to observe the movement of this steel city (suspected) buried in the sand for a while, and then see if there were people in and out, and if so, what kind of people they were, what they were doing, what they were wearing, and how they lived.

But the waits were fruitless.

There was no movement on the top of the city, which the Cogwheel Man called the Answer, and in this eternal night, it was as silent as a tomb.

No one passes through here, and they don't see anyone.

The minds of the young men were stirred up by this. You know, the event itself also represents something, for example, that the top of the "city" is not the area where they live.

He and Chu Yun said:

"The Gear Man doesn't seem to care much about what we do with it. As soon as he arrived in the city, he disappeared immediately, as if this guy had something urgent, immensely urgent to do. ”

"But from the point of view of the 'prisoners' who have been captured by the 'wildlings', the Gearmen are very willing to escape from us, right?" Chu Yun used his little brain and thought seriously, "According to the worst estimate, maybe it will go back to report the news, and soon the city will send a large army to arrest us!" ”

After saying that, she nodded confidently, and suggested with a serious look:

"We may need to get out of here now."

Her guess startled Gu Chuan, but it was indeed a prudent choice.

It's just that Gu Chuan still clearly remembered that the backpacks of the two of them were already empty, and he shook his head helplessly and said:

"But we have nothing left to eat or drink! Even if we were to walk, should we continue in the direction of the compass? Or do you want to retreat to the edge of the mountains now? Which stretch is shorter, and which stretch can we make it out of here? ”

The shadow of the rock covered the two adventurers.

Hatsukumo took off his hood and pulled sand out of his wind-swept hair. The appearance of the Cogwheel People is so strange that they feel strange about the tribe to which the Cogwheel Man belongs, and everything behind it.

"Speaking of which, Chu Yun, do you think the gear man will be some kind of dignitary?"

Chu Yun thought for a while:

"Not like that."

"Could it be some kind of royal and grandson noble?"

"It's not like it......"

"Then even if it is dissatisfied with us, it should not have much energy to hinder us, and we are just two ordinary travelers...... If it is really a city, and has a sufficient population, and is not in turmoil now, it should, or at least should have, some kind of order, some kind of strong order that sustains the mundane and peaceful life of all individuals...... Often this ordinary and peaceful life, I don't think it's too xenophobic. ”

Xenophobia is a possible difficulty.

The point is that they don't necessarily know what's out there...... "At least there's no communication between the city and Sunset City." Judging from the experience of Sunset City, for this city, Gu Chuan and the others are just people who have arrived from a very distant place. Whether they know that there are people outside or not, they will make people suspicious!

Something that doesn't know, it's hard to think about what they're going to do with it.

"Then should we take the initiative to go down and communicate with them?"

Hatsuyun asked rhetorically.

"Maybe you can do that."

Gu Chuan said.

"Let's go, then."

The girl held back her windswept hair, put on her hood again, put on her backpack, and when she had finished speaking, she walked without hesitation to the basin.

The young man was stunned for a moment, and hurriedly caught up with her, walked with her, walked two steps faster, walked up to her, and led her into another civilized area isolated from Sunset City.

The walls of the city, which is known as the "Answer", are very steep.

Standing on the top and looking down, you can see countless kinds of protrusions and depressions, some like hooks, some like needles, some like windows, and some like caves.

"The Cogwheel Man probably got into it from a cave."

Gu Chuan guessed.

They didn't see a gate-like structure, only different modules, large and small.

Hatsuyun knocked on the city wall with his fist, as if he were knocking on his neighbor's door.

But in the end, it was not a neighbor, and the city wall naturally did not respond.

They glanced at each other, cautiously trying to climb the wall, but it still didn't move. Gu Chuan found a cave entrance smoothly, and when he saw that there was light in the extreme depths of the cave, he beckoned to Chu Yun, and then the two walked into the cave together, wanting to get a glimpse of this cave.

The cave allows people to enter, and the road inside the cave is deep and bottomless.

The material that makes up this piece of building is neither gold nor iron, which is different from the material of most of the Sunset City that Gu Chuan knows, or the metal that exists on the earth due to the arrangement of atoms.

Tactilely, it's closer to some kind of mirror or glass, so smooth that it's almost impossible to stand or grip. Gu Chuan accidentally touched a stone, so he slipped forward with his foot and wanted to rush inside.

Chu Yun hurriedly caught him.

Then the two men supported each other and walked forward cautiously.

"It's not quite like an import. If this is imported, isn't it too long? ”

Chu Yun said.

"It does ......"

It's not so much some kind of doorway that opens and closes, but some kind of elongated pipe.

But they couldn't guess what it was, only to see a faint light in front of them, illuminating the glassy metal under their feet, with signs of shattering.

The friction of the broken metal is significantly enhanced, and this road is much better.

"Do you want to exit first and see the other holes?"

"The other holes, I looked at earlier, are also very deep." Gu Chuan said, "We've all come here, let's go to the end, and we're ready to fight." ”

Gu Chuan didn't mention it first, Chu Yun's combat effectiveness was bottomless.

"Okay."

In front of the cracked metal segment were large patches of sticky, near-solid inky black fluid, filling almost a third of the cavern's height.

Gu Chuan stepped on it, and the inky black fluid was like fermented soft bread, causing people's feet to fall into it, and they couldn't fall to the bottom.

There was no obvious discomfort in the legs, just a little chill as if they had touched a heavy sludge.

In other words, this inky black fluid can also walk.

And the further you go, the harder it becomes, and the easier it is to walk, but at this time, the hole is not high enough, and the two people who need to walk to the inky black fluid bend down.

They continued to move forward in this deep pipe.

The boundless darkness and glowing end made Gu Chuan dazed for a moment, reminding him of his escape journey when he was trapped in the underground buildings of Sunset City. The experience irrevocably changed the course of his fate, forcing him to separate himself from his former companions, and occasionally entering his dreams to this day, causing him to contemplate the many unsolved mysteries of Sunset City.

But that's a thing of the past.

The young man laughed, and felt that he was not concentrating enough, and that something was going to be wrong! He hurriedly shook his head, patted his head to make his thinking clearer, and then took a bold step forward, and as for the glowing hole, his vision suddenly opened up.

Then he just stood there motionless.

"Why don't you leave?"

Chu Yun touched Gu Chuan.

Gu Chuan's voice was so quiet that it was terrifying, and he said:

"Look."

Chu Yun was puzzled and calmly took a step forward. Suddenly, the refracted light flashed through her eyes, making her instinctively close them. But she has already had this experience twice. She blinked before she recovered, and her eyes were fixed to see the huge mirror-like polished ore lined up on either side, forming the walls of this huge space.

The light walks back and forth through these mirror-like walls.

"Color-changing stone...... It's a whole piece of space made of chameleon......"

It's like there are at least two spaces in the depths of Sunset City's dungeons.

The only difference is that the surface of the discolored stone walls here is no longer natural, but has a charred blackening.

Hatsuyun shook his body.

There are few things in this world that can make her uneasy.

The things related to the crown are the ones that occupy the most of them.

The pipe they were walking broke right in front of them. Gu Chuan saw that on the other side of the opposite side of him, there was a pipe at the other end that was also broken.

In other words, the pipe that ran through the space had broken for some unknown reason, probably the last day or two.

The consequences of the rupture may have caused the actions of the defenders of the original place.

They release an inky black fluid.

Gu Chuan looked left and right, and saw that the inky black fluid was pouring out of the two nozzles opened by the color-changing stone wall, which had already flooded the lower part of the entire color-changing stone space, and also flowed into the broken pipe.

The color-changing stone is blackening, and according to the nature of the color-changing stone, it means that there are already signs of melting, in other words, these inky black fluids may have absorbed a lot of heat in this space.

The inky black fluid becomes strong when it absorbs heat.

He reached forward and touched the black solids of the inky black fluid.

The black solids are slightly hot, but they are still able to walk.

He took a few bold steps forward, his vision wider.

All sides were covered with inky black fluid, and the walls made of color-changing stone were clean. But the color change stone does not emit light, there must be another light source here.

Gu Chuan raised his head and couldn't find the location of the light source, but he only saw a strange symbol painted on the wall, which was a rice shape. Inside, there is a small circle that runs through all the clues that go straight outward. There is a large circle at the outermost edge that just encloses all the outward segments.

And on top of the symbol, there is a real mirror-like thing.

The mirror is placed in a plastic-like bag that is close to transparent, and it has an outer frame and a mirror surface that reflects light.

The only problem is that the person reflected in the mirror is not Gu Chuan, nor is it this space washed away by inky black fluid, but another ...... I don't know if it's a strange existence of people.

That person did have a human form, just like a gear man, with hands, a main body, and even a set of clothes similar to a suit, maybe under what Gu Chuan couldn't see, there was also a pair of feet similar to a person.

The only problem lies in the head.

Its head is...... A huge pistol-like barrel, or telescope-like barrel. The surface of the reflective metallic luster is extremely smooth, without any unnatural traces of carving, if it is an industrial creation, its level must be so high that Sunset City is difficult to reach, enough to compare with the industrial society of Gu Chuan's previous life.

The reason why the lens barrel head is like a lens tube is because it is topped with a piece of lens. In that lens, Gu Chuan saw himself.

The Mirrorhead let out a strange sound, mixed with a large number of phonemes that had never been seen in the Sunset City language.

"This is the language of the Gear Man!"

Gu Chuan immediately recognized this, and immediately guessed the possible function of this mirror:

"It's the kind of Gear Man! It was supposed to be monitoring the space with a mirror curiosity, and when we walked in, we happened to bump into it and were spotted by it. ”

As he spoke, the figure behind the man swayed.

"They're coming."

Gu Chuan turned his head abruptly.

I'm afraid there is a delay in the display of the mirror curiosity. From the mouth of the broken pipe, several beings resembling the Gear Man already stand.

The only difference is that they are draped in different broken skins.

Some resemble tigers, some resemble pigs, or sheep and horses, and others resemble the skin of monkeys or apes.

Hatsuyun noticed that these skins were strange, and she thought for a while, only to realize that it was because the hairs on these skins were shaved.

They didn't rashly attack Gu Chuan and Chu Yun, but instead made a gesture of please. The gesture of please, according to the communication between Gu Chuan and the gear people, is also common in this country.

But Hatsuun felt an indescribable disgust for these shaved skins, and wanted to reach out to drive them away.

Gu Chuan held her hand.

"Don't be angry, it's not a good idea to fight here."

"Hmmm......"

Hatsuyun responded like a mosquito.

"Let's go with them first."

After speaking, Gu Chuan turned his head and looked at the group of monsters in front of him. He took Hatsuun's hand tightly and said calmly:

"Let's go."

The cogwheel men seemed to understand him, made way for them, and led them down the pipe to a room.

The room has large gears embedded in walls, ceilings, or floors, and a mirror hangs in front of a gear larger than a person that exposes half of the floor.

Behind the mirror, the man with the barrel of the mirror sits.

On the back of the lens barrel man, a pattern of the shape of the rice character is drawn.
