In front of the distance, he saw the earth.

From top to bottom, to be precise, he saw a lot of the earth.

The first earth is the most primitive earth, red, irregular in shape, and sometimes explosions may occur. At this time, the earth is still in the stage of the formation of the earth's circle. You can see that in front of you is a scorching fireball formed by red and hot liquid substances. It can be simply understood that the earth at this stage is itself a liquid planet with molten magma flowing. If humans have imagined hell, then the earth in front of you is such a real flame hell.

As time goes by, the temperature on the surface will eventually drop, and the solid core will gradually form.

Just like Pangu opened the world, the light ones floated upwards, and the turbid ones sink. The dense substances began to slowly move towards the center of the earth, while the dense substances floated on the surface of the earth.

Although it is ironic that most of these low-density substances are solidified by magma, which is what we usually call rocks.

But it's like a lot of metals can float on mercury.

Many times, the density is really a relative question, at least there are many things that are heavier than rocks.

The first earth that Lu Yuan saw was generated, solidified and precipitated over time, as if he was watching some popular science video.

But if you put all this on the bronze door in front of you, this popular science will not be interesting at all.

Instead, there is an illusion that it is cold to the bone marrow as a cultured organism in a glass dish.

Lu Yuan turned to look at the second earth.

The Earth at this stage is generally called the Ancient and Proterozoic universe, and these names sound like ancient and vast.

In fact, the earth at this time has initially solidified from the liquid of the previous high-temperature magma.

Because the earth continuously releases energy outward and performs heat dissipation with the properties of blackbody radiation, water vapor, carbon dioxide and other gases that are constantly erupting and erupting from high-temperature magma, it forms a very thin and primitive early atmosphere, commonly known as the original atmosphere.

Lu Yuan watched the earth finally wrapped in a light gauze coat. As the water vapor continued to increase, the water vapor gradually gathered into rainwater and then landed on the earth.

It can be said that at this stage of the earth, it may rain more than 100 million years.

These rains fall on the surface, which helps the earth slowly cool down, and on the other hand, forms a breeding ground for life.

It is also the birth of the primitive ocean.

Lu Yuan was really excited to see it.

Although these things are not profound and mysterious knowledge for many people.

But in front of you, all this was recorded by this unknown civilization and in such a arrogant and arrogant manner. So where is the human being in this?

Lu Yuan couldn't help but think of this, and the more he thought about it, the more he felt confused and fearful.

Lu Yuan didn't know if Roland and the others saw the real dynamic image displayed after the bronze door was charged.

But even the initially dull 2D still scene has extremely shocking beauty and power.

Lu Yuan didn't know what they thought of this bronze door at the beginning. In short, Lu Yuan was completely impressed by the power displayed by this bronze door.

He could hardly help but look down at the third earth.

The third earth shows the evolution of life.

Just like that wonderful life-creating experiment, various gases are placed in a small closed container that simulates the Earth's atmosphere, and then boils the distilled water and places it in it, allowing them to heat and mix continuously, heat and mix continuously, and constantly release the stimulation of electric sparks to simulate the discharge of nature.

Then it only takes one week to find a variety of the most primitive organic matter and the essential amino acids in this closed container.

It can be said that the substance of life was originally born from this pot of thin and boiling hot soup.

And on earth, this pot of hot soup is the primitive ocean itself.

Various organic matter in the primitive ocean is generated from nothing, and then gathers to form the initial primitive life. Primitive life learns to copy and evolve, and then forms inheritance. It can replicate is almost the initial definition of life. Being able to copy itself means that genetic material can be passed on and can be continuously evolved and derived.

Even if the earth at this time is just a sphere that is mostly submerged by sea water, and the primitive plates are still moving under the influence of crust activity.

But Lu Yuan understood that those initial lives were born in this hot pot of soup.

Listen to the thunder in silence.

Although it should be the weakest time compared to the visual effect at this time, even if the earth is still changing, it is just a pot of boiling soup in this environment, which is repeated and circulated continuously.

Life has been moving forward through continuous trial and error, and eventually reproduces to this day.

Lu Yuan sighed and turned his gaze to the fourth earth.

Next, Lu Yuan saw the emergence of archaeological bacteria, the journey of lithosphere, hydrosphere, atmosphere, and the evolution and generation of life.

He saw the emergence of blue-green algae and the further development of prokaryotes.

And seeing the sudden arrival of the Ice Age.

The originally warm earth was completely frozen by ice and snow in a very short time.

This is the first ice age in the history of the earth, erasing almost all traces of life.

Moreover, this time the Ice Age lasted almost billions of years.

It was not until 600 million years ago that multicellular organisms were born again on this earth, and not long after that the Cambrian life explosion finally came.

Then when the appearance of fish, the prosperity of marine algae, and the naked ferns covering the sky and the earth covered the entire earth, the earth's land was finally no longer naked and desolate.

Lu Yuan saw the prosperity of fish, the emergence of amphibians, and the first insect began to stroll in the jungle. Stone pines and thieves, overwhelming insects almost became the masters of the world, as well as reptiles that began to feed on insects, and eventually the emergence of the coal forest, so that the entire era was named the Carboniferous Age.

I saw a lot of things from afar.

Many, many.

Every earth here is worth studying alone for a lifetime, but there is only one thing that the road will never be forgotten.

He looked at Su Mei: "Did you see it?"

Su Mei nodded quietly.

Yes, they all saw it.

Twenty-nine billion years ago, at the end of the New Ancient period, the first ice age on Earth took place, completely frozen the originally endless warm earth and almost killed all life on Earth. It was not until 2.2 billion years later that multicellular organisms appeared in this world.

"What happened to us today." Lu Yuan sighed.

"What's the difference between that Ice Age 2.8 billion years ago?"
