Desert is a large geographical type, sandy land, desert or desert steppe, can be called desert. They are both a type of desert, but they are different.

For example, sand is man-made, such as over-cultivation and grazing, which can lead to desertification. Deserts are naturally formed and are associated with the movement of the atmosphere and water. As for the desert steppe, as the name suggests, it resembles a desert, but there is still a lot of grass that can be used for grazing.

Between the mountains and the endless desert is a region that can be called a desert steppe, with undulating terrain that resembles hills. There is also a lot of grass and trees in this area, and it only took Hatsuyun a little time to find enough firewood and a water source. The good news is that there is no rain at the edge of the desert, and dry things are prone to burning. The bad news is that the water source is a little far away, and you have to walk for half a day in the mountains. Chu Yun took great pains to carry a leather bag of water.

When she filled the pouch, she tied a knot for fear that the water would overflow. Then, she looked up, and saw this boundless desolation scene, and suddenly remembered the words of the toeless man at the beginning—

Is there no end?

"Why did he ask that?"

Hatsuun didn't understand this. She hugged the firewood and carried the water and began to walk back. On one side was a desert that seemed to have no end, and on the other side there was an end, but she knew that the mountains were very long.

The pristine mountains undulated like waves on the water, and the winding and blurry moon resembled a boat on the waves.

At her feet were the dried roots of the grass that had been turned out, and her eyes were drawn to the boat.

The light moonlight seemed to follow her.

Hatsuyun soon found that when she was in the mountains, the moon hid between the mountains, revealing only a corner, and when she reached the mountain, the moon did not disappear, and she hid between the mountains as usual, but it seemed to chase out a distance, and also revealed a corner.

"The moon doesn't seem to be the same as the sun, the sun is always hanging over the water. So, the maid said that the sun was like a majestic elder and the mother of Sunset City, and the moon, I said, was like a shy peer who would only hide behind a wall. ”

She muttered to herself.

"Ah, then I know the character of the moon......"

Thinking of this, Hatsuyun smiled happily as if he had discovered a big secret. Her steps became lighter, and the man walked back with great triumph.

At that time, Gu Chuan was still in the soil cave, and he first piled the weeds together to make a temporary sleeper. When he was done, he hummed a small poem that only he could understand, went to the mouth of the earth cave, and continued to ponder the gear machine by the dim moonlight outside the cave. The young man was lost in thought, but his eyes were serious, and his hands touched the tightly constructed geared machine, turning it over and over several times.

"The tooth shape seems to have a bit of a taste."

The real gear is not ideal, there is an error in the tooth shape of the gear, and it may be that the upper groove on a gear is not the same as the groove below.

But Gu Chuanguang couldn't see the difference in the tooth shape of the gear with his eyes.

"Perfectly fitted with the involute, fitted perfectly, it's not a little superfluous, it's not a little vacant...... Excellent high-precision industrial products. ”

The operation of the gear is very intuitive, it is not like the electronic chip of the transistor, you can only see an etched circuit, and you can't understand it. It's like one wheel driving another, and the other wheel driving the odd hinge, which goes on to drive the next wheel, or brings up some straps, always making the curious boy think he can figure it out.

So Gu Chuan's hands gradually reached into the gap between the gears and the gears, and he wanted to pry the gear machinery open and disassemble it in a destructive way. But at this time, he found that the gear machinery was neat.

Any part of him moved, as if he was fighting against the whole machine. All the power is encompassed in an incredible way. The whole machine was like a clockwork clock, but it gurgled and turned because of his strength. But his strength was not enough, so the "clock" did not turn long.

But the more this happened, the more annoyed the young man became, and the more he wanted to take the gear apart. He began to wrestle with the gears, and he picked on a large gear in the chest of the gear machine and tried to pry it off.

But after a try, he found that the gear obviously seemed to be set on the pole, but the top of the rod was completely flush with the gear itself, and he couldn't even feel the gap of friction when he touched it with both hands.

When Chu Yun returned to the entrance of the cave with the moonlight, what he saw was that Gu Chuan was vigorously swinging one of the two gears on the chest of the gear robot, as if it was about to be torn off.

"Aren't you afraid of breaking it? If it breaks, you can't fix it, can you? ”

Chu Yun put down the firewood and a bag of water and asked Gu Chuan.

"Oh...... Right...... It seems to be going to break. ”

The young man woke up from a dream, touched his head stupidly, and rubbed his hair. The man's hair was already long, and the messy strands of it hung down over the shoulders, and with the long journeys and dust, a fresh young man became a raunchy savage.

He got up from the gear machine and began to prepare to take out the ignition from the firewood.

Chu Yun sat next to him, drilled wood with him, looked at the gear machinery again and asked:

"Why do people make machines look like humans?"

The humanoid features of this geared mechanical body are very iconic.

According to Gu Chuan, the first thing is to stand upright. Legs and feet are common to most animals, but erection is a typical human characteristic, embodied in the human body as the spine is perpendicular to the ground, as is the case with this large geared machine, which has a long spine-like axis that supports the body, and the legs are connected to the body almost completely perpendicular to the ground, which is obviously intended to imitate humans.

In addition, in addition to its upright body, it also has a human-like face, eyes made of light bulbs, and a mouth that can be opened and closed like a doll.

But why did he make this human figure, Gu Chuan really couldn't answer it.

He pushed the gear machine into the hole a little, and then agreed with Hatsuyun's doubts:

"You've got an idea! There must be a terrible mystery here...... That's why is there a machine above Sunset City's level that is humanoid? Did they make geared machines, like the writing clocks that I sought from the craftsmen to make according to my opinion, in order to flatter some supreme superior? ”

The hole is not big, the fire is set up in the depths, and the smoke can sink and injure people. The boys and girls chose to drill wood near the entrance of the cave, and wisps of smoke soon grew from the wood, drifting into the sky.

Then in this remote no-man's land of the world, in this cold fairyland, a small flame emerged.

The flames shimmered.

"You have a point."

Hatsuyun frowned.

The fire burned silently in her eyes.

"Not necessarily...... There could be many more amazing possibilities! Who knew that Gu Chuan said with a smile, "Maybe it's not this machine that imitates people, but people who imitate machines...... Maybe? This is about first come, first come, who knows if there will be a machine or a person first? ”

Chu Yun was stunned for a moment, and remembered the legend of the birth of man in the ancient Sunset City.

According to the philosophy of water and soil, everything is a mixture of water and earth, and people and things are a handful of mud thrown to the ground.

Gu Chuan continued:

"It may also be that the human form itself has some special secret, so all the higher things will be made to the human form!"

Another new speculation followed, smashing Hatsuyun unconscious.

She began to think about it carefully, and felt that all three of these statements seemed to make sense.

"But maybe, none of this is true."

As Gu Chuan spoke, he took out the large curved bone piece that they had used to hold water before. This bone fragment is also peculiar, it looks like a helmet, but it does not seep water, and although the heat conduction is not good, it can barely be used as a pot.

They also had some wild vegetables in their bags called Phi Hua that they had dug up earlier. The flowers are easy to distinguish because they have purple petals that look like butterflies. The reason why this wild vegetable is called Phihua is because the flowers are not delicious...... Or it is difficult to eat, and the rhizome is fat and tender, and it tastes like a camellia, and the leaves are round and plump, which can be used to serve alcohol.

Rizhao Village often uses the flowers of the flower as fertilizer for the field, and then picks the rhizomes separately to eat. Sichuan mother every busy season, often take out the leaves and rhizomes of the flower and sprinkle the brine, mix some green onions planted at the door, and fermented tempeh, it is a good cauliflower, the flower tastes a little rare sweetness, if you mix some meat, it is endless tender and sweet. Gu Chuan remembers this vividly.

However, there are no compost wild vegetables such as flowers in Sunset City, and Hatsukumo didn't eat them before escaping Sunset City.

But she is not a picky eater, Gu Chuan feels that she can live with whatever she eats.

"However, I may be able to live by eating anything now......"

He thought.

But he still has a sense of hunger and a sense of taste, and if there are good things, why not eat good ones?

It's a pity that there is no salt, and it is annoying to take water, so you can only wash it slightly, remove the skin film, and throw it into the pot to boil. Chuanmu said that the soup boiled by the flowers was extremely clear, and the moonlight sprinkled on the bone fragments had just been boiled, and it was still bright and bright.

When they were tired, they leaned together and lay down on the haystack, and began to agree on the question of who should keep vigil. They had not forgotten the beast and the alien who performed the ritual.

The firelight swayed in the wind, like a bright dream in a dark world.

"Last time, you were the first to guard, this time I will guard it."

Gu Chuan said.

"Nope." Hatsuyun shook his head, "No, I'll stay a little longer." ”

"Why?"

Gu Chuan was puzzled.

"I'm remembering the position of the moon." Hatsuyun closed his eyes and began to construct a picture of the moon rising in his mind.

"What is there to remember about the position of the moon?"

"You said the sun was creeping down below the ground, didn't you notice?" Hatsuyun reopened her beautiful gray eyes, as if sharing a great secret, and whispered urgently, "The moon has been secretly following us!" ”

"Huh?"

"Previously ......"

Hatsuun began to talk triumphantly about her previous discovery.

Gu Chuan was still listening carefully at first, she thought that Chu Yun had noticed some moon movement, but halfway through hearing it, the boy laughed.

"And is the sun secretly following you?"

"No, the sun is not...... The sun is not so lovely, it does not follow me secretly, but ......" Hatsuyun frowned and said, "Monitor me openly, watch everything I have, and examine everything I do. ”

Gu Chuan was suddenly speechless, and he began to feel sorry for Chu Yun's past.

There was no sound in the eternal night, and the desert was as quiet as a deep sea, and the waves reflected the moonlight.

The moonlight shining on the water is cold and untouchable. But when it shines on people's bodies, it seems to feel the temperature again. Hatsuyun lay beside him, gazing with him at the endless night sky. The firewood crackled. He quietly grabbed Hatsukumo's hand.

Gu Chuan's hand was hard, and it was as hot as a blood. Hatsuyun's little hands were extraordinarily weak, and they felt like a cool velvet that would melt at any moment.

She turned her eyes sideways, and there seemed to be light in her eyes. Chu Yun suddenly thought of something and asked Gu Chuan:

"Gu ...... How did you know about the moon? ”

Gu Chuan blinked, and Chu Yun continued:

"We used to live in a world where there was only the sun, it turned out to be the moon that I had never seen, and the root of the word moon you used came from a dark old word, and I didn't recognize it when I read that booklet......

When it comes to the booklet, Hatsumo is even more confused. She asked:

"Your mother...... Told me that...... You wrote that book, isn't it? Actually, the adventurer you're talking about doesn't exist at all, does it? ”

Gu Chuan leaned on the hay, without any quibbling, he became extraordinarily honest:

"Yes."

"But how do you know all this?"

It is difficult for the young man to explain this, for for his past life is like a dream that is so clear that it grows farther and farther as his life in this world continues, and if it were not true knowledge, then he would suspect that this past life was nothing more than a grand hallucination of his mental illness.

He said melancholy:

"I dreamed about it in my dreams."

This is not lying.

This made Chu Yun's eyes widen in surprise, she actually believed it, and said with heartfelt emotion:

"That's amazing......"

Then it suddenly fell low again.

Because she also wanted to have such a magnificent and mysterious dream, but she never did it, and it is estimated that it will not be possible. This inability to do so casts a shadow of distress in her bright eyes.

"Well, how could I not do it?"

Hatsuun began to roll on the haystack in annoyance, from left to right, and from right to left, causing the young man to laugh.

Just then, the water boiled.

Mother Sichuan didn't lie to Gu Chuan, the soup with cauliflower was really very clear, from boiling to boiling, it was so transparent that it seemed to be glowing with moonlight.

Chu Yun ate quickly, while Gu Chuan ate slowly.

When he bit through the cauliflower, his eyes were still looking at Chu Yun's eating state. The girl puffed out her cheeks because she chewed vigorously, fleshy, and extremely cute.

Gu Chuan glanced at his eyes, looked around at this small temporary home, and casually swept the gear machinery behind Chu Yun...... It was only after a moment that he realized something, and swept it back with a pretended nonchalance.

He noticed that the gear machine seemed to be inexplicably shifted a few centimeters from where he had been placed.

Although a few centimeters is short, Gu Chuan's memory is very good.

He bowed his head silently, pretending not to notice.
