Wang Yang wants to see the ice age, so what is the ice age, let's find out first.

A geological period in which the earth's surface is covered with massive glaciers. Also known as the Ice Age.

The only period of relative warmth between ice ages is called an interglacial period.

There have been many ice ages in Earth's history, the most recent being the Quaternary Ice Age.

In the history of more than 4 billion years, there have been many significant cooling and cooling, forming ice ages.

In particular, the Late Precambrian, Carboniferous to Permian and Cenozoic glaciations were long-lasting geological events and are often referred to as the Great Ice Age.

The time scale of the Great Ice Age was at least millions of years.

During the Great Ice Age, there were many large periods of alternating cold and warm climates, and periods of expansion or retreat of the ice sheet, which were glacial and interglacial.

Obviously, Wang Yang was in the middle of the Great Ice Age, and now he is developing towards the Ice Age.

Not only in this era, but in modern times, we are also in the middle of an interglacial age.

The famous Quaternary glacial period began 2.5 million years ago and continues to this day.

We are now living in the Quaternary glacial period.

At the beginning of the Quaternary glacial period, glaciers covered the entire Northern Hemisphere. Then ablation began, then covered, and then abled.

The most recent ice age to us began about 110,000 years ago and ended between 9,600 and 9,700 BC.

At its peak, around 18,000 years ago, the upper third of the Northern Hemisphere was covered in snow and ice.

Modern times are in an interglacial period, so you don't have to feel unfamiliar, and the development of industrialization. There is a certain greenhouse effect, and the heat of the climate can be seen in general.

Maybe. Before Wang Yang was born, the transition to the ice age had already begun. It's just that Wang Yang doesn't know.

Now that he wants to see the ice age, let's move back another four months.

On this day, Wang Yang woke up from his dream in a good mood, and after waking up, he began to look for food to eat.

When you're done, we're going to clean up the animals.

Then, he's going to expand the house of the Animal Gate.

If someone asks him why he wants to expand again, and whose expansion is it? He would have pointed at the man and replied, "You're too humorous." ”

In an environment where food and clothing are worry-free and free from the world, which small animals reproduce quickly. Rats are undoubtedly.

In the fall, they number more than 100 individuals, and now, many months later, they have grown up and matured, mating and reproducing.

There are dozens of female mice that are pregnant and about to give birth.

As long as they live, their numbers will increase several times, and three or four hundred will not matter, and the room is much larger than other small animals. It becomes completely inadequate.

Expanding the house becomes imperative, and you can imagine how noisy it will be when hundreds of rats gnaw wood and chirp together.

Can Wang Yang endure it? Of course I can bear it. He can't be happy in such a good situation, what can't he bear.

He's pretty much cleaned, and the adults are pretty much equipped. Get ready to go hunting in the forest.

Today's weather is good, although the land is covered with snow and ice. Everything withered, and from time to time a cold wind howled. However, there is no snow, so it is relatively dry and stable, which is suitable for hunting.

After the blow of last year's unexpected situation, they realized again that it is not advisable to be content with pleasure and the status quo.

In the past few years, their winter has been getting better and better year by year, and they have become easier every year, they don't need to face the threat of wild beasts, they don't have to hunt, they don't have to work, they have a little numbness, as if winter is on vacation, nesting around the campfire to keep warm, what are you doing outside.

But this year they won't make the same mistakes again, the difficulties have made them more realistic and ready for anything.

So until now, they have been holding on to hunting as long as the weather allows for a long time outside.

It is now the fourth month of winter, and this and then will be the time when food is most scarce, and even if they go out, they may not be able to get prey, and they are likely to waste their time and experience.

However, due to the good practices of the previous months, this year's food storage has reached an unprecedented level, and today, half of the stored food has been consumed.

Even if there is no gain at all in the next four months, you can eat and drink comfortably for another four months.

In this way, there is no fear of extending the winter at all, even if it is eight months?

Therefore, Wang Yang is not worried about doubling the number of small animals at all, and he is not afraid of the increase in the population of the tribe.

The number of people in the tribe has indeed grown considerably, from more than 40 last year to more than 50 this year, and is about to reach 60.

More than a dozen new lives have landed in the first ten days and come into this world.

Wang Yang is very happy, and he is very energetic in doing things.

He and a few friends brought in a tree, broke all the branches, and took the thicker branches to the campfire in the cave and burned them.

And he borrowed the power of fire to burn the marked places on the trees, and burned them for a while, knocking the black carbon apart, preserving it, burning it again, and knocking it open again.

The area that has been burned by the fire will be charred and brittle, and it does not take much effort to intercept the length you want.

Then tie the trees to the length and expand the house.

It was very tiring to carry the trees to burn all the time, so Wang Yang found several thick branches, tied them together, and made a tripod.

Wherever you want to burn, move the tree or tripod down.

After a few days of busy work, he made a wall and took it to the rat house for comparison.

This expansion, there is no need to make four walls as troublesome, only the front and back and right sides, because the left side is the rat house, and the front and rear walls are docked with the rat house with ropes, which is a ready-made wall.

The works were completed a month later.

The fifth month, which was originally the end of winter, was spring.

However, Wang Yang has confirmed the coming of the ice age, and does not have this plan, the weather has not changed, it is still dry, the temperature has not risen, and the snow is getting thicker and thicker, and it has not melted at all.

As the month passed, the number of rats had suddenly reached four hundred, and the two large houses and the back of the cave were full of rats, and the sound of rats resounded day and night.

Wang Yang still couldn't stand the sound of his ears chattering all the time, and had to run outside the canyon to be quiet and quiet during the day.

These noises are also quite disgusting to other small animals, and the chicken boss sometimes finds a big mouse to duel, one is noise, and the other is the compression of the environment.

If you think about it, you finally endured the cold and noise for a night, held back until the daytime of the wind, and wanted to find a place to bask in the sun, but the surrounding area was densely packed with large and small rats, can it be better?

Even the civet cat, which once had a deep long-cherished wish with it, put aside its blood feud and fought on the same front with it, looking at the flooded rats with red eyes every day, planning ulterior secrets. (To be continued......)
