The twenty-fourth episode of the end of the first world

Four billion years ago.

The vast sea is vast, but surprisingly calm, making the water surface free of wind and waves. The land is empty, desolate, and as silent as death, lifeless.

Crossing from the South Pole of the earth to the Mediterranean Sea, and then from the Mediterranean Sea to the West Malayas, all the way through, the desolate scene made Chen Baohua feel a little lonely and a little afraid!

Standing on Mount Everest, looking at the ancient mountains and rivers, he wanted to see the hustle and bustle of the city, the smoky villages, and the busy scene of traffic...... ，

However, in the end, all that came into view was the vast sea and the red, yellow, and black colors of the land.

It is conceivable that if the earth is empty, there is not even an ant, there is no noise, there is no noise, not even a slight ultrasound will occur, and you can hear your own heartbeat without paying attention to hearing.

There is no life in the vast world except for the two of them.

Strictly speaking, Xiao Fang is not a life at all, at least it cannot be said to be a complete life! Then, he is the only life in heaven and earth. In fact, to be more strictly speaking, he Chen Baohua is also a product of 4.5 billion years later, he just traveled back to 4.5 billion years ago, at that time, without his existence, there was no sign of life on ...... earth.

It's the height of summer, and the sun is shining on the earth.

Standing on a flat coastline in the subtropical sea, he bent down and held a handful of seawater and stared at it for a long time, hoping to see the existence of life, and he tried his best to understand the mystery of the origin of life on earth.

"Life originates from water, but it is a very slow process!" Xiao Fang pulled Chen Baohua away from the place where the waves could not hit, and said, "If we want to see creatures breeding, we need to stay and observe carefully." ”

"How long will you stay?" Chen Baohua looked at the empty places around him without shelter from the wind and rain, and was a little worried, he said: "How can you live without a house or tent?"

"If you want to know about the origin of life, you have to stay and observe, or you will give up the desire to know the origin of life, and we will go back. Xiao Fang said straightforwardly.

"Go back, isn't that in vain?" Chen Baohua shook his head like a merchant: "No, you can't go back, just stay, fortunately, the weather is very hot, and you can't freeze." ”

For several days in a row, Chen Baohua stood on the seashore and carefully observed, trying his best to see if there was any change in the water.

After many days, Chen Baohua suddenly saw that the water quality was different from the previous day on a scorching afternoon, and a large area of seaweed had grown on the sea surface due to the impact of the hot tide

Chen Baohua was very happy and happily jumped high on the beach. He finally saw aquatic life in the water for the first time, and although it was just a patch of seaweed with no signs of life yet, at least he saw hope. After all, he must have seen the first creatures on earth. Ignoring the danger of the waves, he went straight to the depths and picked up a handful of seaweed, and was pleased to take a closer look, when he was suddenly surprised to find a small insect that looked like a small insect attached to the seaweed.

He exclaimed excitedly, this was the only life he had seen since the birth of the earth.

He wondered how these insects looked, very much like mosquitoes in stinky water, could it be that the first life in this world was a mosquito? Perhaps more life would follow, and he carefully put the seaweed back into the water.

More than ten days passed, and on that cool morning, he dragged Xiao Fang to the beach early, as expected, a bigger surprise was in front of him, and he began to find that the insects attached to the seaweed had become countless small tadpoles, and there were countless black presses.

Holding a handful of tadpoles in his hand and looking at it again and again, after the most embarrassing, he happily kissed the tadpole, and shouted wildly on the coastline while being happy. The joy is palpable.

Xiao Fang looked at him excitedly like a child, and couldn't help but think of what the child in her belly looked like? Like him, like herself, she didn't know.

Suddenly, Xiao Fang felt a pang of discomfort in her stomach, and she knew that she was about to give birth. The thought that she was about to become a mother made me happy and nervous at the same time. I am happy that her love affair with Chen Baohua has finally crystallized, and the nervousness is because she has no experience in giving birth for the first time. She didn't know what preparations a woman needed to make for childbirth.

But there is one thing she understands, the baby in her womb is coming soon. Therefore, she must let her husband understand the process of the origin of life as soon as possible before she gives birth, so that she can go back to give birth.

So, she pointed to the sky with her hand, and a wide canopy was immediately reflected in the sky, and the vast sea and even the whole earth were reflected in the canopy.

Through the picture, Chen Baohua saw that the tadpoles gradually changed as they grew, and finally lost their tails, and then turned into ...... of various species of fish and other marine life.

In these lives, there are many things that are different from fish, and there are different limbs and claws of fish, and these small animals of different shapes have four legs and two legs, and they keep climbing ashore in the process of growth. Among them, dinosaurs are one of them.

"The life of the earth comes from the comet that hit the south pole," Xiao Fang said, "and the moment it hit the pole, it poured its own ice and water on the earth, and those ice and water contained a lot of biological elements." It was the huge tsunami that sent all kinds of biological elements to various seas and some freshwater lakes, including land. The biological elements carried by the comet are buried in the Earth's soil, which is affected by temperature and humidity, and a large number of plants are first cultivated in the soil.

It's the same with living things, which breed all kinds of organisms at the right temperature. Saltwater, that is, seawater, breeds more fish, and most animals on land breed in freshwater. Many things, as your so-called experts say, that life on Earth originated three billion years ago. In fact, life has existed on Earth for a short period of time since the birth of the Earth. The first life on Earth was fish and insects, which went through a rather long evolutionary process that lasted more than a billion years. All animals living on land evolved from aquatic creatures, and dinosaurs were no exception.

At first, aquatic animals climbed onto land to forage, and they could not leave the water for too long, about a few tens of minutes to a few hours before they would return to the water, otherwise they would be dried up and killed.

Over time, about a few hundred million years later, they have evolved to the point where they do not need to go back to water, but only drink enough water to replenish when their bodies need it, which is why animals need to drink water. ”

Xiao Fang is like a narrator, and as the picture continues to change, she explains to Chen Baohua one by one: "At the same time, while marine life is breeding, some freshwater lakes also form a large number of organisms. A wide variety of plant ...... also grows on land. ”

"I want to know now what kind of animal evolved from human beings?" Chen Baohua was a little impatient.

"This question is not a mystery for human beings, as people think, human beings evolved from apes, and at first, apes were very capable of surviving, eating all kinds of plants and fruits, and adapting to all kinds of harsh environments. The evolution of the apes depends on labor, and labor cultivates and evolves human intelligence, first someone discovered the energy of fire in a burning fire after a tree was struck by lightning, and thus knew how to use fire .........!"

With the picture in the canopy and Xiao Fang's explanation, Chen Baohua has a general understanding of the process of human evolution from the picture.

"The evolution of apes into humans was quite a long process...... Xiao Fang felt a huge pain in his abdomen, covered his stomach with both hands and said to Chen Baohua, "I am about to give birth, I have to go back to 2012 quickly, and we can't let our child be born in this ancient era." ”

"But, but I still want to know how the dinosaurs became extinct?" Chen Baohua was a little unwilling.

"It's too late to take you there, I can only tell you. Xiao Fang continued to point to the sky screen and said: "In the middle of the Jurassic era, the rulers of the earth have always been dinosaurs! But a mass extinction at that time completely overturned life on the earth! According to today's words, it was the end of the first world!"

"The end of the first world?" Chen Baohua looked at Xiao Fang with a questioning gaze.

"Yes, according to you humans, there is a definite number for everything. Maybe that's providence!" Xiao Fang continued: "At that time, there were two kinds of dinosaurs: carnivorous dinosaurs and herbivorous dinosaurs. ”

"That is to say, there are those who eat meat and those who eat vegetarians!" Chen Baohua replied.

The same can be said. Xiao Fang continued: "Suddenly, another comet has come to the earth! This comet is several times larger than the comet that hit the south pole of the earth last time. Its power is even more astonishing! It crashed into the Americas at once, separating the earth's continents and dividing the Americas into two parts, north and south. That's what is now South and North America!"

"Ao!" Chen Baohua seemed to understand something: "The continent that people often say is divided is caused by this comet. ”

"Yes!" Xiao Fang continued, "Under the impact of this comet, a strong shock wave almost hit most of the earth, causing the vast majority of life to die in that disaster! Dinosaurs are no exception?"

"Can the dinosaurs be extinct in that disaster all at once?" Chen Baohua was skeptical.

"No!" Xiao Fang said, "most of the lives died, and a very small number of survivors died in the ensuing volcanic eruptions and crustal changes, and thus became living fossils." What ultimately made the dinosaurs extinct was the extreme anomaly caused by the comet's impact on Earth. The high temperature has continued to change to more than 180 degrees Celsius for nearly 30 years, and no rain has fallen for 30 years. All the creatures and plants on the land route are dying of thirst, starvation, and dryness!"

"Ao!" Chen Baohua finally understood.

"That's not enough!" Xiao Fang continued, "Next, there will be nearly thirty years of continuous low temperatures. The low temperature reached almost minus 120 degrees. ”

"Ahh However, the facts cannot be denied.

"This is the whole process of the end of the first world! Now it's time for us to go!" Xiao Fang didn't leave Chen Baohua a chance, and forcibly took her husband through the ...... of time.
