In the history of the 21st century, the Earth had one of the oldest, longest, and harshest ice ages millions of years ago.

At that time, the oldest human chordate ancestor had not yet appeared at all. Because of the excessively bad weather, the whole earth is like a huge ball of ice and snow......

That era, called the Varangir Ice Age, is about 5.8-750 million years old so far.

- No, no, no!

This idea was so terrible that Zhou Shuangshuang hurriedly shook her head and tried her best to throw out this terrible thought.

She took two deep breaths, sat down in front of the fire with her knees crossed, stared at the orange flames, and began to slowly calm down.

INTERVIEWER Now, now that there are people, it will certainly not be as long as 750 million years.

And she checked the information, the most recent ice age from the present, according to the time period of the 21st century, only about 10,000 years ago.

- The cold is gradually spreading from the ends of the earth to the middle, the glaciers have been extending from the poles to the equator, and the climatic conditions are difficult for people in the 21st century to imagine!

And in this terrible time of disaster, mankind has already appeared.

Moreover, our human ancestors still survived this harsh environment with great difficulty, and planted the initial spark of reproduction for everything we have today.

………………

And now, Zhou Shuangshuang has felt colder and colder.

The fire was clearly extinguished, and even if she added a circle around it one after another, it was still not enough.

The branches and leaves in the grass shed slowly intertwined with cold and heat, and cold frost flowers slowly leaked out.

Zhou Shuangshuang took a breath of hot air and gradually started to ......

The next moment, she suddenly thought of something, and jumped up quickly like a fire burning her buttocks!

While running wildly, she picked up two alloy sticks from the space and quickly jumped out of the shed.

Then, hit it vigorously with two metal rods, making a loud, "bell-bell-bell" sound.

In this silent and uninhabited night, it is said that it is far away, far away.

……………………

What is she doing just now, what is she doing in the things of the glacier, the top priority is to call everyone up!!

- Fool!

She ran, constantly striking the alloy rod with a sound, and she was about to burst into flames!

——The temperature is so low, even in modern times, there are still old people who are reluctant to use warmth every year to die silently in the cold weather.

And now, even if there are still many fires in their caves, their physical fitness is far beyond ordinary people...... But minus 20, no, it's minus 40 degrees outside, you can't take that risk!

And at this moment, the anxious Zhou Shuangshuang is still worried: If this severe cold does not dissipate until dawn, how will they live?

……………………

At this moment, when her feet stepped on the grass, she could make a "creaking" cracking sound.

It was the sound of blades of grass being crushed from the extreme cold.

Zhou Shuangshuang ran back and forth, and couldn't help but sigh in her heart: I knew earlier, I wouldn't let them marinate meat today. If it's such a cold weather, if it's no longer warm...... Cured meat is not necessary at all.

The black and flat land in the distance was also the result of their hard work during the day.

At this moment, she regretted it in her heart - she knew it earlier, she knew it earlier!

Even if they are allowed to go out hunting, more prey is better than any farming! Now I don't know what the climate and environment are, so I let them do things according to their own ideas......

Isn't it a harm to them?

………………

Her thoughts were mixed, remorse kept coming to her heart, and the movements of her hands became more and more urgent.

As the sound of "bells" continued to ring, the cave gradually became aware of the trembling of people coming out.

And the moment they stood out of the cave, someone immediately noticed that the temperature was abnormal, and hurriedly followed Zhou Shuangshuang's voice, Ula Ula called out.

Zhou Shuangshuang looked at everyone's expressions as if they were facing a great enemy, and felt faintly relieved in her heart.

In this way, they have experience - this situation should have been done before.

Thinking about the hot sun during the day and the cold temperature at night when he arrived before, Zhou Shuangshuang couldn't help but think boldly-

Could it be that when she came, it was already early winter?

……………………

Whether it was early winter or not was not known for the time being, in the middle of the night, everyone went out and quickly got piles of firewood stained with ice flowers from the bushes next to them. The thickness is uneven, and the size is different.

As soon as the wood was hugged to the fire, it was steaming with heat, and it turned into ice flowers that had congealed on it.

For a while, the sound of fluttering and dripping was endless, and soon, there were clumps of water in the soil.

Qi watched everyone's movements, but at this moment, he walked up to Zhou Shuangshuang and solemnly beat his chest.

He opened his mouth to say something, but he seemed to consider that Zhou Shuangshuang didn't understand, and finally only turned a thousand words into two words-

"Frost."

The rich gratitude that could not be dissolved made Zhou Shuangshuang couldn't help but be shocked.

Kai had already turned around and followed everyone to collect the branches.

He was so serious, and he was like a great enemy, Zhou Shuangshuang immediately had a conjecture:

- If they have encountered this climate before, then it also means that in this environment, they can only rely on animal fur or leaves to keep warm and cold without fire.

In this kind of bad weather, even if the people of their small group hug each other, I am afraid that they will not be able to escape the doom of freezing to death.

No.

Zhou Shuangshuang quickly overturned her idea again.

Qi Gang's expression was not half confident, as if he had never experienced such a thing. However, he, as well as his people, have a sense of methodical movements......

Zhou Shuangshuang guessed that they must have experienced cooling before, but those so-called cooling must be far inferior to this time!

Perhaps, this is really similar to the historiography, the ice age 10,000 years ago!

I don't know how the ancestors of mankind survived this kind of weather?

And now, with the flames, wouldn't it be much more likely that they would survive and survive this bitter cold?

………………………………

The second half of the night passed.

It's dawn.

Zhou Shuangshuang almost didn't have the heart to do anything, at this moment, she just sat by the fire quietly and worriedly, looking at the sky.

The horizon has long been white.

There, the orange glow shimmered, and the sun had not yet shown its tracks.

She prayed silently on the side: Thousands of thousands, to raise the temperature!

Maybe she prayed too hard, or maybe it was the endless road of heaven.

The next moment, a touch of orange jumped, and the whole world began to brighten. The ravines of the mountains and valleys in the distance were bright and dark, and the earth was covered with a pale golden light......

It was dawn and the sun came out.

Zhou Shuangshuang looked at the thermometer that was re-hung on the side, and half an hour later, the temperature above it slowly rose.

By about eight or nine o'clock in the morning, the temperature had risen to 10 degrees.

She breathed a sigh of relief.

Kai had already packed up, and with an axe and sharpened sticks, he pulled all the men and women who were strong and good at hunting, and set out for the forest together.

- An unprecedented winter is coming, and it's time for them to stock up on food.
