"This is the ......" Duan Fei, who was still confused about these symbols a moment ago, can now understand the meaning of these words, although he can't translate them word by word, but it is not difficult to understand what the whole text is describing.

There are two stories depicted here, the first of which is about the illusion of the origin earth.

3.5 billion years ago, when life first appeared, the Earth was completely different from today's Earth, when the Earth had just emerged from a cloud of gas, dust and rocks, although the composition of the atmosphere was uncertain at that time, but there was no doubt that the gas composed of carbon was the main element, dense carbon dioxide, and possibly methane, no oxygen at all; The sun at that time was also different from the sun now, and according to the theory of stellar evolution, the temperature of the sun at that time should have been too much than it is now

The sun temperature is 25~30% lower. In the early days, the greenhouse effect of carbon dioxide in the air around the earth kept the earth warm and life continued, but as the temperature of the sun rises, the sea becomes hotter, and more and more water vapor enters the atmosphere, plus hundreds of billions of tons of carbon dioxide stored in carbonate rocks, if it continues, the greenhouse effect will eventually get out of control, and the earth will be like the current situation of Venus, the surface will be covered with thick carbon dioxide gas, and the high temperature can melt lead. Fortunately, about 2 billion years ago, cyanobacteria began to appear in the oceans, and they used photosynthesis to convert carbon dioxide in the air into organic carbon compounds. Over hundreds of millions of years, cyanobacteria and the plants they evolved into have evolved and multiplied so much that the increase in carbon dioxide in the atmosphere coincides with the rate at which the sun is warming. The theory holds that it is life itself that saves the entire world of life.

On the other hand, the earth has never been calm since its birth, and in addition to various droughts and floods, hurricanes, tsunamis, earthquakes, and volcanic eruptions, it is constantly bombarded by rock fragments from space. Most meteorites are small enough to be harmless meteors, and a few large ones reach the ground. On average, about 100 million years,

There was a huge meteorite that hit the earth, injecting a large amount of dust and gas into the earth's atmosphere, blocking the sunlight, causing great disaster to the earth, a large number of species extinction, the most recent occurred about 65 million years ago, and made the dinosaurs that ruled the earth's land at that time extinct.

This mass extinction seemed to be the first mass extinction in peacetime, but it was only after the appearance of the ruins of the ancient gods that humans really realized that it was the first extinction.

Comets can both bring life to Earth and threaten the life that exists on Earth. Comets can give birth to life, and when they were given to Earth 4 billion years ago, they can continue to give birth to life. These rudimentary life forms may have been brought to Earth by comets, or they may have come to our world because the dust left in orbit by comets fell to the surface of the Earth. These are strange life forms to our earth creatures, in the form of some filtered viruses, and Hall boldly assumes that these "comet viruses", both in time and structure, are out of touch with our higher earth animals, and conversely, the earth creatures have no resistance to these "comet viruses".

When the meteorite fell three years ago, the virus descended on the world, and the human world was completely turned upside down, and all kinds of creatures evolved wildly, which is the same reason as the wave of meteorite fall that exterminated the dinosaurs hundreds of millions of years ago.

Did life on Earth originate from land or ocean, or was it carried by asteroids from some distant part of the universe? To this day, the question of the origin of life on Earth remains a mystery for scientists. They often have different opinions. The planet we live on was formed about 4.6 billion years ago, and in a way, something must have happened at an uncertain time, as this lifeless celestial body began to accept something very different from rock and water.

Nitrogen and carbon molecules evolved into DNA, a microorganism that travels between the stars of the universe...... It is an indisputable fact that millions of years after the appearance of this tiny molecule, primitive single-celled bodies were born, and then slowly more and more complex aquatic organisms appeared, which eventually landed on land, and since then various organisms have multiplied and spread on a large scale on the earth.

There are about 2 million different species of organisms on Earth. However, this is just a number before the apocalypse, and after the apocalypse, this number rises to an incalculable number, all kinds of creatures fuse with each other, and then continue to devour the genetic nuclei of other mutant beasts and then mix and evolve, even if there are different biological genes on the human body, there are different kinds of zombie gene nuclei, there are different abilities of mutant beasts, they fuse with each other in the human body and absorb each other, transforming into a new hybrid individual.

But all kinds of organisms originate from the same substance—a substance that, to some extent, initiates the course of life. What kind of substance is it? This article will elaborate on the latest theories and research results on life on Earth. The fragments of some celestial bodies cruising in space are like a gang of "robbers" in the universe, and sooner or later they will collide with a certain celestial body. But some of the comets and asteroids that collided with the Earth may thus become the creators of life on Earth. It is very likely that it is a comet that brings a lot of water to Earth, and without it, Earth would probably be a dry planet forever.

Seeing this, Duan Fei couldn't help but wonder, the previous mass extinction was because of meteorites, and this time the mass extinction of humans was also because of meteorites, whether there was any mysterious connection between this.

At this time, the second fantasy was automatically opened, and the scenes entered Duan Fei's eyes and came into his mind.

This is a paradise-like beauty, the first thing that attracts Duan Fei's soul attention is the phenomenon in the air that cannot be explained by physics, the floating large and small stones slowly rotate like a spinning top, countless iron chains connect the stones to each other, and there are all kinds of strange tall plants on the ground, some plants are more than two hundred meters high, like a skyscraper.

Behind these scenes, in the clouds, a dreamlike island appeared, with tens of thousands of buildings on it, and the scene was quite astonishing.

Sou! All the illusions were retracted in an instant, and a red symbol hovered in front of them. Duan Fei, who touched it lightly, screamed as if he had been electrocuted.

Ah——!h
