The snow covered the entire deserted mountain range, and there was not a trace of green to be seen on the continuous peaks, and the few weeds that were there were now withered and drooping, and a few vultures flew through the sky, making a terrible cry in the snow.

The snow the size of a goose feather no longer floated in the sky, and before the faint snowflakes could fall to the ground, they had already turned into a drop of cold rain in the air layer and hit people's bodies.

Wu Chen, with one of the tribe's hunting teams, was walking in the snow at the moment, with crutches in his hands, and the plains of the riverside area were covered with white, and the river water was covered with a thick layer of ice.

Shao Lin carefully stabbed the ice with the cane in his hand a few times, some fine ice slags were scattered around, but the ice was very thick, there was no trace of cracking, several Yanyi tribesmen carefully walked to the ice, and after confirming that it was correct, Wu Chen led the group through the ice and walked into the distance.

"Look carefully and be careful about your surroundings." Wu Chen's brows furrowed slightly, and the exhaled breath quickly condensed into water droplets in the air, turning into a white mist.

All the warriors kept breathing, rubbing their hands, trying their best to keep their stiff fingers soft, the cold wind came from the surface, so cold that Shao Lin closed his eyes, the wind blew like a knife across every part of his body, and the shoes sewn from animal skins under his feet were already a little wet.

The traces of animals on the snow had been covered, and even Ah Da, who had a sensitive nose, could only drag his body and follow Shao Lin's side, carefully sniffing the smell with his nose on the ground as he walked, but he didn't smell anything.

"Whew." Ah Da shook the snowflakes on his body, and the wet and cold snow water was thrown on Shao Lin's body, and Shao Lin glared at Ah Da.

"Wu Chen, the snow was too big before, and the traces on the ground were also covered with snow, so it's hard to find." Chi Zhan glanced at the white snow, which had submerged to the height of his calf, and as soon as the hot air in his mouth erupted, it turned into white mist when it met the cold current in the air.

Wu Chen nodded and looked at the ground.

Before winter, the mammoth herd had left the area during the tribe's hunting, and the smooth stone walls of their bodies were still on the stones in the distance, and it was the first time I had heard such strange cries in the winter in the Deserted Mountains.

Saber-toothed tigers and steppe wolves should all hide in their dens at this time, and will only come out to forage for food when they are really hungry, and the same is true for white-tailed eagles, winter is an extremely severe test for any giant beast as it is for humans.

What the hell could it be?

Ah Da didn't know if his little master came out for food today, he just tried his best to sniff the smell carefully on the ground.

"Woo?!" What does it taste like?

Ah Da frantically used his front paws to throw the snow on the ground like a dog.

Noticing Ah Da's strange appearance, Shao Lin squatted down and looked at Ah Da.

"There's something down there?" Shao Lin looked at the wolf he had raised suspiciously, and then stretched out his hands and began to toss.

A lump of black, yellow, black and yellow was hidden underneath the snow, giving off a faint smell of grass and some stench, and the Yanyi people who were familiar with every giant beast near the desolate mountain range could tell at a glance that it was a lump of feces belonging to an adult mammoth giant elephant!

"Brother Wuchen! Brother Wuchen, here! Shao Lin jumped into the air and waved violently at Wu Chen.

Wu Chen and Chi Zhan glanced at each other, trotted all the way to Shao Lin on the snow, and saw the feces that had been thrown out of the snow by Ah Da.

Chi Zhan reached out and picked up a small piece of feces and broke it open, the feces had become a little hard because of the long-term storage in the snow, and there were many yellow undigested grass in the dung that had been removed, Chi Zhan frowned, and muttered to himself: "It can't really be a mammoth giant elephant, right?" This dung is full of grass, and only the dung of mammoths will look like this, not the dung of horses, elks, spotted donkeys, and eagle-toothed beasts. ”

Taking a closer look at the feces in Chi Zhan's hands, Wu Chen supported his jaw with his hand.

The mammoth giant elephant suddenly appeared in winter, and Wu Chen couldn't figure out what was the reason for the mammoth giant elephant to be abnormal and appear at the border of the Yanyi tribe at this time.

The cold air in the air continued to roll and churn, then rush, surging everywhere over the deserted mountains and river valley plains.

In the Yanyi tribe, Yue Lin was anxiously waiting for the tribal warriors to return from the survey, and a dozen or so black dots in the distance suddenly appeared on the horizontal line of the Yanyi tribe, which was particularly dazzling on the snow-covered earth, and the white feathers in the sky waved huge wings, and only after the warriors of Wuchen and the Yanyi tribe returned to the tribe safely, it flew back to its nest on the fibrous tree.

The main branch of the fibrous root tree is extremely large, even Bai Ling's huge body can only occupy a small territory in the canopy of the branch, at this time Bai Ling's nest is different from before, the bird's nest is not only covered with soft and warm fur, but also made of wood and some dead grass above the bird's nest to build a hut to cover Bai Ling's excess snowflakes.

Bai Ling stepped on her bird's nest with her foot to see her belly that was bigger again.

"Goh?" Why hasn't it been born yet!

The flames drove away the wind and frost on Wu Chen's body, and Yue Lin brought Wu Chen a cup of freshly boiled water and handed it to the man.

The man took a sip and sat down by the fire, scorching his already wet leather shoes with the flames.

The leaders of the tribe, large and small, were now sitting in the huts, baking fires to keep warm.

Wu Yang sat on the only stone bench in the room, his voice was rough but low, obviously he was also particularly concerned about that strange cry, "Wu Chen, what's going on outside?" ”

"We found this." Wu Chen motioned for Shao Lin to put the feces in his hand on the table, and the leaders and team leaders of Yan Yi, who was experienced in hunting, frowned slightly when they saw it.

When Zuo Feng saw the feces, he was not sure, and he wondered for a long time, "That cry is really from a mammoth elephant?" ”

"No, I remember they migrated two months ago, and every year they don't return to the valley to give baby mammoths until the beginning of summer!"

Wu Yang stared at the dung silently for a while, and said to Wu Chen: "Tomorrow with the warriors of the tribe, we will have a little more people to go to the place where the dung was found and look carefully." ”

Ram Lie and the others also agreed with Wuyang's words and nodded one after another.

The night sky slowly fell, and the sky was sprinkled with such snowflakes and cold, and the snow came so quickly that the snow pressed the branches of the trees and pressed down on a winter forest.

The tribesmen have been carefully surveying outside for the past few days, but they have not seen any dangerous beasts near the tribe, and the cry of the strange mammoth elephant has always been a mystery.

In his hands, Yuan Hehyuk held two planks that were full of his chest, the upper end of which was made into a curved shape using the method given to him by Yue Linwu, using methods such as fire and water vapor, and two long cylindrical walking sticks.

He impatiently walked through the snowy and unwalkable roads of the Yanyi tribe to the outside of Yuelin and Wuchen's huts.

"Knock knock."

Yue Lin put down the things in his hand and ran over to open the door, only to see Yuan Hehe shivering in the cold wind, and the jacket he was wearing was tightly pulled by Yuan Hehe with his hands to wrap his body, preventing the cold wind from blowing in.

"Yue Linwu, this is what you asked me to make for you." Yuan Hehe handed the wooden board in his hand to Yue Lin's hand, and the polished smooth wooden board had no extra wood chips on the surface, and it would not scrape human hands.

Yue Lin took the thing, "Hehe, I'm really bothering you, come in and roast the fire, it's too cold." ”

Yuan Hehe wanted to rush in and hug the stove the moment the door opened, and experience the warm breath, this year's winter is too cold, colder than any previous winter, even the long and cold winter ten years ago is not as cold as this winter.

He cowered down and walked into the neighboring hut, moved his body to the fire, and stretched out his hands to roast on the stove.

"What did you ask Yuan Hehe to do?" Wu Chen glanced at the wooden board that Yue Lin put aside strangely, and asked suspiciously.

Yue Lin smiled, handed a cup of boiling water to Yuan Hehe, and said to Wu Chen: "Sled, use it for you, when the snow stops in a while, I will teach you to use it." ”

Yue Lin felt sorry for Wu Chen, and braved the heavy snow every day to look for suspicious traces outside in the past few days, and specially asked Yuan Hehe to make a sleigh for Wu Chen.

Wu Chen smiled and nodded.

Although everyone didn't want to move in winter, the soldiers still nagged their wives or let their slaves make them new vehicles for the winter.

The children also made their own hands, happily sledding and having snowball fights in the snow.

The tribal warriors continued to search and reconnoiter for seven or eight days.

The room was sitting in the room with hot air and rubbing his hands, when suddenly a high-pitched shout came from outside.

"Sister-in-law, sister-in-law!" Wugu's face was red from the cold, and his tall body could not grow, at least no less than three centimeters tall, and the tall and burly body of the young man stood in front of the door of the hut, panting constantly, obviously running all the way.

The snowflakes stained his temples white, and his dark hair was haphazardly tied together by the boy with hemp rope.

Yue Lin looked at Ugu strangely, brushed the snowflakes on Ugu's eyelashes with his hand, and said, "What's wrong?" Come in first. ”

Urgula grabbed Yue Lin's hand and said, "Don't sit, don't sit, Brother told me to bring you to the gate immediately!" said that I found a good thing today, and asked my sister-in-law to hurry up and see it! ”

Good stuff? Wu Chen said that it was a good thing, it should be a very important thing, Yue Lin pulled the animal skin on his body, wrapped himself tightly, and after seeing that there were no other flammable materials around the burning stove in the house, he put on a straw hat made of grass and followed behind Wugu.

Walking through the huts, Yue Lin finally saw the tall figure of his lover Wu Chen, who was standing in the center of everyone at the moment, staring at him with a pair of narrow dark eyes.

Yue Lin walked in front of the man, the man stretched out his hands and hugged Yue Lin, holding Yue Lin's head with both hands.

The ears were now pressed tightly to the man's chest, listening to the powerful beat and rhythm of the man's heart.

"You're in such a hurry to call me out, don't you just want to hug me here?! The people are watching! Yue Lin gently pushed the domineering man, smiled slightly, and said in a somewhat dissatisfied tone.

Wu Chen let go of the person in his arms, smiled, took out a small bag sewn from the animal skin clothes, took out an object from it and handed it to Yue Lin's hand.

"Look what this is!"

The blue crystals were mixed with some other unknown substances, emitting a brilliant light under the reflection of the bright snow, and the more Lin looked at the things in his hand in surprise, and then raised his eyes to look at Wu Chen, and his mouth grew.

Yue Lin fiddled with the things in his hand, "You found the copper mine?" ”

Wu Chen smiled noncommittally at Yue Lin, pointed to a short and somewhat thin boy on the side and said, "He found it by accident." ”

The boy had a pair of peach blossom eyes, his hands were red from the cold wind, and he had some chilblains on his ears, and at this moment he was a little nervous by everyone's eyes, and his whole body was shivering in the cold wind.

Yue Lin looked at the boy for a year and felt that this child looked a little familiar.

"Bai Mu, tell me where you found this stone, and the location of that mountain." The voice of Chi Zhan came from behind Bai Mu, Bai Mu shivered, subconsciously bit his lip, raised his head tremblingly, met the eyes of the tribesmen, and looked at Yue Lin.

"I ...... I don't know how to describe that place, but I remember the way, and I can take you there. Bai Mu was frozen and stiffened, carefully observing Yue Lin's expression, after all, his sister almost killed Yue Lin Wu, although Yue Lin Wu pardoned himself and his sister Bai Ash's crimes, but the tribesmen obviously didn't think so, they spit on and hated themselves and Bai Ash.

After finally figuring out why he felt that the young man's face was familiar, Yue Lin nodded lightly, looking at the young man's obviously thin body, and the only animal skin clothes on his body that could not wrap his whole body, and some parts of his arms were still □□ in the cold wind, frowning slightly.

Yue Lin took off a square animal skin draped on the outside and handed it to the young man, "Put it on, it's cold, and the animal skin is not enough, so ask me for it, or ask the leader for it, you know?" Small children should not be exposed to the cold. ”

Bai Mu looked at the animal skin that Yue Lin handed in front of him in a daze, not knowing what to do, how long has it been since no one cared about him? The boy lowered his head and tears rolled in his eyes.

Sighing, Yue Lin put the fur in his hand on the young man's body, and said, "Wear more, don't be cold, it depends on you to take us to the mine, you are a great hero of Yan Yi." ”

"Great hero? What is that? The young man looked at Yue Lin suspiciously, and asked puzzled.

Yue Lin patted Bai Mu's head and said, "It's the one who has made a great contribution to the tribe!" ”

All the Yanyi warriors were ready to put on their sleds, and relied on the route indicated by Bai Mu to find the mine located in the northwest corner, which was actually very close to Yanyi, not in the territory of the craftsman tribe.

There are a lot of dark blue copper ores in this hill, as well as brass and spotted copper, but most of the copper ore is red copper with excellent ductility, which is very pure, and it is an excellent material for making copper ware.

"Great! Wuchen, we can make arrowheads out of copper, and copper knives, which are much better than wood! Yue Lin looked at the copper mine, smiled happily at Wu Chen on the side, stretched out his hand and took the initiative to hug Wu Chen, and buried his head in Wu Chen's chest.

"It would be better if you could find iron ore! Am I being too greedy? Yue Lin grinned to himself.

Wu Chen was happy when he saw Yue Lin, hugged Yue Lin back, and said in Yue Lin's ear: "I will find it, believe me." ”

The thin child on the side grabbed the soft fur on his body tightly with his hand and looked at Yue Lin.

Wu, I'm so happy, it seems that this blue thing is really useful, but why did Lord Chi Zhan ask me to say that I found the copper mine? Obviously, Lord Chizhan has already found this place!

Bai Mu looked at Chi Zhan who was standing upright with a pair of good-looking peach blossom eyes, his little head was puzzled, he clenched his fists, Lord Chi Zhan actually gave this credit to himself in order not to let himself be embarrassed in the tribe because of his sister?!

It must be so!

Bai Mu's eyes shining as he looked at Chi Zhan at this moment.

Chi Zhan was numb by the strange gaze, and when he looked at it, it turned out to be the extremely timid Bai Mu, and he couldn't help but pout the corners of his mouth.

Bai Ling was guarding the periphery, looking at the sky with a pair of cold eyes, and there were a few small birds flying in the sky, flying unsteadily in the air, obviously hungry and a little exhausted.

"Goh?" Why haven't you come out yet, I want to!

Bai Ling pouted her buttocks, ready to free her stomach.

"Bah-"

Bai Ling's outstretched wings paused on both sides of its body like a penguin, and it carefully moved its huge body, and when it saw several white objects behind it, it was so anxious that it spun in place!

"Goo, goo, goo!" What to do, what to do, my eggs are born!

Bai Ling stretched out her wings and wanted to touch her egg, but she couldn't pick it up!

Bai Ling looked at his paws again, and gently touched the gray-white egg on the ground with his foot, and immediately retracted, the claws were too sharp!

"Goo, goo, goo!" Big bald monster, come out, I've laid eggs!

Hearing Bai Ling's hurried screams outside, Yue Lin and Wu Chen thought that Bai Ling had discovered some danger and hurried out.

I saw a huge white-tailed eagle carefully rolling the egg on the ground to the entrance of the cave with the tip of its own wings at the moment, and when I saw Wu Chen appear in front of me, I immediately gently rubbed Wu Chen's head with my head.

"Goo!" Big bald monster, what now, my eggs are out!

As soon as the others touched the eggs, Bai Ling looked at the clansmen holding the eggs with a pair of eyes coldly, and the three eggs on the ground could only be held by Wu Chen in the end, and the more he hugged one, he brought it back to the Yanyi tribe.

Bai Ling, who was sitting in the bird's nest, thought about her egg being taken away by the big bald monster, and her head was buzzing.

"Goo!" No, I've got to keep an eye on my eggs!

Wu Chen sighed and looked at Bai Ling, who was lazy at the door of his house, so he had to set up a new nest for Bai Ling in the open space in front of his hut with branches and fur, Bai Ling squatted happily inside, knocking on the door with his mouth from time to time, and asked Yue Lin to open the door and look at his eggs.

"Bang bang bang-"

When night comes, the snow in the sky gradually decreases.

Wu Chen, who was holding Yue Lin on the bed and preparing to show off his skills, heard a violent knock on the door, pulled over the fur and didn't want to pay attention to it, and kissed the person in his arms deeply, but the knock outside the door became more and more urgent, and then the whole hut began to tremble.

"Ho-ho-"

"This dead bird is going crazy!" Wu Chen grabbed a handful of his hair with his hand, let go of Yue Lin in his arms, got up from the bed and walked over to open the door.

Bai Ling's head swooped into the hut, and her smart eyes looked at her three intact eggs in the room through the crack in the door, and then she paced back to her new nest next to the hut with confidence.

"Goo!" Remember to open the door for me early!

Wu Chen turned to look at Yue Lin, who was already holding his stomach with a smile, with a bitter face.

Although the snow is heavy, there is a district of people walking on the road in the valley plain, who are walking in the snow with some stones on long sleds made of wooden planks and two pieces of wood on their feet.

The recent routine of the tribal warriors is no longer to look for traces around the tribe, but to transport a batch of copper ore back to the Yanyi tribe, and the rest is not mined, because Yue Linwu said that he still needs to study how to use this new thing.

The snow had stopped for days, and the clearings that had been swept away were nothing but bare black dirt, not even a single grass.

Yuan Hehe burned the furnace, Yue Lin kept tinkering with the copper mine, although he knew some principles, but it would take some time to actually smelt copper, and since he discovered the copper mine, Yue Lin was thinking about how to make the head of the arrow every day.

In the winter, the more Lin was shirtless on the edge of the stove, the more Yuan Hehe Gang was blowing the wind, and the more he looked at the copper ore in the furnace that had begun to decompose, anxiously waiting.

Suddenly, a hurried sound came from a distance, and footsteps whipped across the snow that was swinging on the ground.

"Sister-in-law, sister-in-law! Oh no! ”

Ugu panted and ran in front of Yue Lin, bending over to his chest and panting.

Yue Lin glanced at Wugu strangely, and asked suspiciously: "What's wrong, you kid, why do you scream every time you look for me?" ”

Wugu casually picked up the water on the side, hurriedly poured two sips, took a breath, looked worried, and said to Yue Lin: "Brother and Abba quarreled just now!" ”
