Everything that is considered eternal will eventually pass away in a form that is not eternal.

A similar phrase is a saying that has been circulating in Sunset City for a long time, just like the "eat a trench, grow wiser" or "an apple a day, the doctor will stay away from me" on the earth, few people care about the origin, but most of them will be heard in the child's raising stage, and only in the education stage and education stage, some people will use it repeatedly.

It's just that no one in Sunset City would ever doubt that the sun that never sets will do the same.

The mountains are vast, stretching out on this land where no one knows the truth.

The people in the mountains don't know where they are.

Some time after the moon was discovered, it began to rain lightly in the sky. The rain, which was completely different from the previous irritability, was as gentle as a soft mist, permeating the mountains and forests, and I didn't know that the rain was coming.

There are no clouds in the sky, and no one knows where the water comes from. If you look behind you, the moon is hidden in a mountain that towers to the sky.

In Gu Chuan's knowledge of the shape of the moon on the earth, such a moon is called a crescent moon or a moth eyebrow moon because the shape is like an eyebrow. If the moon becomes slightly brighter, it is called the first quarter moon. Why is it called the first quarter moon? It's because of the gradual fullness of the moon, like pulling the bowstring.

But Hatsuun said no.

She said seriously:

"More like a deep, lonely eye. However, this eye has not yet opened, but cautiously hides in the mountains to look at us secretly. ”

The rain was light, but the mountain road was slippery, and they did not dare to run more, so they found another cave as a temporary shelter. There are many pink mountain peach blossoms growing on the side of this cave. In front of the clusters of mountain peach blossoms is a lake where deer are raised. The fawn was drinking water, and when he saw someone coming, he hurriedly ran and jumped away.

The infinite mountains and the rain are reflected in the clear water. The young man fetches water from the lake, then sits down on the smooth pebble bank, tests the temperature of the water, generously takes off his coat, and immerses himself in the water, so that he can wash his body.

This is an experience that Gu Chuan has not had in the era of the earth's civilized city. But on this land, in Rizhao Village, which is accompanied by water, it is also an inevitability of life needs.

He pulled back his shirt and looked down to see the tight wound on his abdomen glowing a fiery red, distinctly different from the rest of his body. Naturally, the coagulated scar will not be thin and tender, let alone polite...... It was terrifying like a charred old tree, showing a fibrous, grid-like hardness, like a tangled stiff beard.

"There seem to be signs of improvement."

The young man muttered.

Compared to before, the abnormalities born from the forcible sticking of the immortal flesh and the skin showed signs of spreading, and the scope became larger, but the degree became lighter, and the original crack was like a big black mouth with jagged teeth, and it was only barely stitched up by Hatsuyun with a thread.

"What will become of me?"

He saw himself in the water.

The concept of the Strange Creatures stems from the need for a stable inheritance of strange things, but apparently, the inner city is also imperfect until they escape from Sunset City.

Sunset City uses strange things that already know what they are used for.

As for Gu Chuan, he relied on the strange things that Chu Yun suddenly picked up in the underground to renew his life. What will become of this life, he does not know.

Because there was no cycle of the sun and the moon, neither Gu Chuan nor Chu Yun could judge the passage of time, nor did they know how many days and nights had passed. They are always in a state of resting when they are tired, going to bed when they are too tired, and continuing to rush south after sleeping.

But during this time, he felt that the changes in his body in terms of "growth" or "aging" became dull and slow.

The hair has continued to grow. He told Hatsuyun to cut off the hair with a sewing needle, so that it would be uncomfortable for the hair to cover his ears.

This phenomenon has been observed for too short a time to be believed.

But another phenomenon surprised Gu Chuan.

That is the increase in the temperature in his body. For example, the water in the lake near him was originally cold, and after he soaked for a while, the temperature of the water next to him had risen to more than 30 degrees. The flies that flew from the surface of the water, just bitten the edge of his skin, as if they had touched a flame, and flew away, only a short distance, and then staggered into the grass and died.

Gu Chuan retracted his gaze and thought:

"The original owner of this piece of immortal meat may be an extremely high temperature thermostatic animal......

Animals are divided into two categories. One is homeothermic animals, such as humans, who can maintain a constant body temperature, usually around 37 degrees Celsius.

On the other hand, ectotherms are unable to maintain a constant body temperature, and the body temperature changes with the environment. To a certain extent, this temperature change system determines natural phenomena such as hibernation of snakes and migration of fish.

Based on his observations of these otherworldly creatures, they can probably be divided into these two categories.

"If that primeval creature is, then its internal temperature may be slightly higher than that of a human, at least high enough to kill me!"

It is not difficult to rely on the medical common sense of Gu Chuan's primary school level. Although the temperature in the human body is 37 degrees, the fever to liver and kidney failure and respiratory and circulatory failure is only about 41 degrees.

The knowledge that fever needs to be cooled down is present in this world. The principle behind fever may also be used in this world.

"Or did I get some kind of benefit that I didn't know?"

Worried, he got up from the water, put on his coat again, and returned to the cave wet.

There was a fire in the cave, and Hatsuyun was resting on the hay that was piled up. Her eyes were closed, her legs curled up, and her mouth was still muttering about the moon, the crescent moon, the first quarter moon, and so on.

Gu Chuan generously exposed his body to roast the fire, so that the moisture on his body would disappear as soon as possible. The warmth and comfort of his body after washing his body was a long-lost happiness, and he hugged his knees, rested his head on his knees, and looked at the moon in the forest, knowing that he was in a corner farther away than Sunset City.

"As a result, things always start with a beginning that wasn't first envisioned."

He muttered to himself.

There is no map, just a needle that doesn't move.

There are no tools, just your own bare hands.

Even the companion is not the companion he originally envisioned, but an unexpected and strange person.

The thin moonlight shone in the rain and mist of the forest, and the boundless dim sight made him feel sleepy.

When they looked out from the top of the mountain before, this area was already the end of the mountains, and further south, there was a lonely and cold desert Gobi. There was a thick fog on the Gobi, and the fog went all the way to the sky.

This is where the last trees are.

The presence of trees in itself may prove that this is the last place where the sun's rays can reach.

"But with our current resources, it is very dangerous to cross the great desert."

He thought.

"We need to take a long detour. It doesn't matter if you take a long detour...... But when will we encounter new civilized villages and towns? ”

Where there is civilization, there are resources.

And now, he felt like he was crossing an otherworldly Himalaya. Sunset City is a miniature version of the Great River civilization at the foot of the Himalayas, and not even a savage can be seen otherwise.

"Not really...... Aren't the complete savages here? ”

The young man smiled when he saw the girl's sleeping position.

Chu Yun didn't know Gu Chuan's smile, but continued to hug himself tightly until his head and legs changed positions in the haystack.

The next day was unknown.

The world is still immersed in a hazy light rain.

Rainy days are not suitable for long treks, suitable for doing something else.

The two put on water shoes and raincoats, ready to find some materials nearby. The original water shoes showed signs of damage during the long journey, and Gu Chuan wanted to see if he could make rain boots similar to "clogs" out of wood and straw rope. The construction of the clogs themselves also prevents the feet from being scratched by thorny plants.

The two of them walked one after the other in the small woods by the lake in the mountains, looking for suitable wooden materials.

The search was fruitless.

All the trees are excessively soft, sparse and prone to breakage. The farther you go, the fewer trees there are, the less grass you have, and only large patches of moss remain.

But unexpectedly, they ran head-on into a wild deer that was running by.

Gu Chuan's eyes lit up:

"You can't let it go! Today's and tomorrow's food should be all on this deer! ”

Yesterday he went to the shower, and today he was fully dressed.

Hatsukumo is equally unambiguous.

She looks like a quiet girl, and in people's impression of a girl, she should be sentimental. But Hatsuyun was different, Hatsuyun was taught that people were of the same kind and could not be killed, but she was not taught anything else, so she killed other small animals, whether they were flies or large mammals, without any mercy.

Two people combined, outflanked before and after. The panicked deer also tried to ram the two with its horns, its horns had killed many other creatures, but this time the wild deer ran into a hard stubble, and its head was smashed by a flying fist, and the skull was completely shattered, killing him on the spot.

Gu Chuan carried the carcass of the deer on his shoulders and said happily:

"I had something to bake and eat at night, but unfortunately ...... It's a pity that we ran out of salt. ”

Halfway through, the young man looked distraught and frustrated, more painful than when the pursuers were chasing and they fled as fugitives.

Before they left the mine, they stuffed a large bag of mineral salt into their bags made of animal hides. Whether the mineral salt can be eaten or not, whether it is healthy or not, Gu Chuan does not know, but these two strange people don't care. As a result, the mineral salt was even finer and more delicious than the coarse salt normally eaten in Sunset City, and they had eaten it by the time they crossed the fifth mountain.

"Shh......h

The girl made a silent gesture.

Gu Chuan stopped talking, and saw Chu Yun first looking left and right, and then walking forward in the direction where Lu came. The half-wet, half-dry ground left a series of hoof prints of deer.

"Did you see anything?"

Gu Chuan followed with the carcass of the deer on his back.

She walked over to the shade of a tree and brushed aside the blades of grass, under which a strange human-like footprint appeared.

There were many footprints, but most of them were buried by rain and withered leaves.

"That's a big problem......"

Gu Chuan lifted his chin thoughtfully.

Yesterday he was still thinking that he hadn't even met a wild man, but now it seems that this is not the case.

They did not dare to go deep into the forest, so they returned to the cave with the carcass of the deer in their arms.

But by this time the bonfire they had raised in the cave had been extinguished, and the haystacks had been turned over in a mess. Fortunately, the important things of the two of them were carried with them, so there was no loss.

The two looked at each other and only talked about some ordinary things to arrange.

Chu Yun calmly rekindled the fire and erected the shelf with wooden branches, while Gu Chuan skillfully began to dissect the deer and cut it into pieces.

Outside the cave, it was still gloomy and dark.

Hatsuyun glanced from time to time, and when she glanced outside the cave for the third time, she saw a dark shadow by the lake.

The shadow was thin and long, like a tree growing on water, motionless, like a ghost. She was about to go out, but saw Gu Chuan shaking her little thumb.

This meant telling her not to make a move.

Hatsumo was puzzled.

Gu Chuan said with his lips:

"Let's see what that thing does next."

Their pots were in wagons, so now they don't have pots, and at most they boil them with some dew from the bones of washed and dense animal pellets. The main body of the deer is roasted directly separately.

As the flames heated, the smell of unadorned pure roasted meat spread from the cave to the outside of the cave.

But their minds were not on the deer, but outside the cave.

The moonlight poured into the forest, and the lake had a few silver waves. The shadow still stood there, motionless, like a flag.

Chu Yun took out the pelvic bowl with both hands, and waited seriously for Gu Chuan to cut a few pieces of plump meat for her, but Gu Chuan said:

"The shadow is gone."

She blinked, still holding the bowl seriously. Bone pieces, she was very cleanly washed. Being alive is the most important thing, and eating is the most important thing.

"Let's chase it first!"

Gu Chuan put down the blade and cautiously came to the mouth of the cave. Hatsuyun followed behind him half annoyed, and poked the flesh of the waist of the young man who was suddenly ready to take an adventure with his fingers. Gu Chuan didn't look back, he was still looking into the distance, and after a while, he stretched out a hand.

Chu Yun looked back at the meat that had been roasted in the cave, barely grasped it, and at the same time looked forward with Gu Chuan's gaze.

The shadows are not gone, but after watching them for a while, they move.

Assuming that the direction of the definition needle is south, then the direction in which the shadow is moving is east.

He continued to walk east through the woods.

The two cautiously followed behind the shadow, and saw that in the dim world, the shadow that had been watching them had reconciled with another shadow in the woods. The two shadows muttered a lot.

After a long distance, we approached a mountain gorge.

They saw that various stone caves had been drilled into the gorges on both sides, and in each cave there was a pile of flames burning bright red.

The firelight arranged on both sides illuminates the stone altar in the middle. The altar was hollow, and a lot of hay was piled up inside, and many things were placed on the altar. Gu Chuan and Chu Yun couldn't see clearly, they only saw that there seemed to be a deer that was still struggling, and there was also a python that was still bouncing after being dissected...... There were also black sacks propped up in the center of the altar.

The blood of the animals flowed all over the altar.

Below the altar, all the shadows knelt on their knees, and read poems with repeated syllables that they could not understand, toward the moth-eyebrow moon at the end of the gorge.

"What are they doing?"

Hatsumo was puzzled.

Gu Chuan looked from afar and guessed quietly:

"Perhaps, they wanted to use the blood of the originally living animals slaughtered to honor the heavens or ancestors to make a pious ritual to protect the fate and future of their own race."
