Li who opened to the white door also stretched out his hand, and he still seemed to be holding a black card in his hand?

I saw Li holding the card in his hand and swiping it gently towards the white door in front of him, and the white door opened automatically.

"Amazing!"

Seeing that Li opened this white door with just this card, Mu Chen and Song Qi couldn't help but marvel in their hearts.

Is this the result of mechanical technology?

Opening the white gate, Li and Ti also walked into the area behind the white gate one after another.

After stepping through the white gate, Li and Ti arrived at the wheelhouse (as the name suggests, it is the command room that controls the entire starship. On a round platform in the center, there are also many dense and complex buttons.

At the front, several large glass panels isolate the outside world from the cabin environment.

Through these huge pieces of glass, Mu Chen and Song Qi were also able to clearly see the space environment outside the starship.

The vast stars, shining with sparkling light, dotted the universe that was originally a void, and made the universe that was dark and lifeless a little more vibrant.

Walking into this cab, Li slowly came to these huge pieces of glass, quietly looking at the endless starry sky outside the window, not knowing what he was thinking.

Homesick?

Or are you thinking about how to attack Earth?

Although Mu Chen is very sympathetic to the plight of these people, even if he can't fight it, he can't just abandon his homeland!

Not to mention that now that these people still have the idea of the earth, Mu Chen will never allow such a thing to happen.

No matter what kind of reason these people have, in short, it is a crime to take the initiative to invade other people's homes, although Mu Chen has to admit that the civilization of this bird does not planet is very developed, but Mu Chen believes that as long as he says that he cultivates well, he will definitely be able to help his predecessors protect the earth together!

Ignoring the li who was thinking by the window, Ti went straight to the edge of the round platform, stretched out his hands to control those buttons that Song Qi couldn't understand at all.

Clicking on these buttons and clicking on them, an image suddenly appeared in front of TI.

Sensing the image mobilized by TI, Li also hurriedly withdrew his gaze looking at the vast void and turned his head to the image mobilized by TI.

I saw that there was a simple circular mark on this image, and not far away, a small triangular mark was connected by a dotted line to the circular marker, and various numbers were constantly appearing on the blank area on the side, and the small triangle mark was also constantly approaching the circular mark along the dotted line.

This......

What seems to be the real-time distance between this starship and Earth?

"If we continue to sail at the current speed, we should be able to reach the Earth completely in three days.

According to the information sent by the main ship just now, it seems that the creatures on Earth are not united, and there are a total of four realms.

According to the latest research report, the biotechnology on this earth is still at the third level, and the mechanical technology has not made any progress at all, and it cannot even be called the first level.

Looks like we've got the right bet this time!"

Looking at the image that suddenly appeared, Ti also smiled softly at Li on the side.

"Without the support of mechanical technology, our spacecraft will not be discovered at all when it enters the earth, no way, in fact, I am not too willing to invade these planets, but if you are backward, you will be beaten, this is the eternal responsibility, and if you want to blame it, the civilization of this earth is too backward. ”

Hearing Ti's contempt for the earth, Li couldn't help but smile, ridiculing the backwardness of the earth's civilization.

And when he heard about himself, even Mu Chen couldn't help but be disgusted with these alien civilizations.

Bullying the soft and fearing the hard, a typical waste civilization!

Time passed slowly until the starship reached the outer part of Earth's atmosphere.

During the starship's voyage, Ti and Li also honestly controlled the starship, communicating with the main fleet from time to time.

From the communication between Ti and Li and the so-called main fleet, Mu Chen and Song Qi also understood that because of the large number of crew members carried by the main fleet and the extremely heavy weapons they carried, they could not quickly sail in space.

Compared with the main fleet, the exploration fleet that only carries some special materials, that is, the spaceship that Ti and Li are piloting now is indeed much lighter, and there is no need to consider too much data in high-speed navigation, so this is the reason why this starship can reach Earth so many years earlier than the main fleet.

It's just that......

Coming to the outer periphery of the Earth's atmosphere, Li and Ti are also carefully regulating all kinds of data, so that the starship can withstand the impact from the Earth's atmosphere when it enters the Earth.

Looking at the blue planet in front of him, even if there is a deep darkness around him, the stars exude a charming pale white light, but everything is not as beautiful as the earth, so beautiful and immaculate, transparent and crystalline. The pale aqua blue color brings it a quiet beauty, and the same texture makes it even more vicissitudes. Mysterious and elusive, beautiful and intriguing.

The Earth is particularly beautiful in the universe: the blue part is the vast ocean, the green part is the dense forest, the white part is the perennial snow, and the yellow part is the vast desert.

In the history of the Earth that we know, scientists on the planet Bird Don't have conducted systematic scientific research on the origin and evolution of the Earth, starting in the middle of the eighteenth century in the Bird calendar, and various theories have been put forward so far.

Birds don't poop are generally believed to have the Earth as a planet that originated from the primordial Sun (the star of the solar system in which the Earth is located) nebula 4.6 billion years ago.

Earth, like other planets, has undergone a number of common physical evolutionary processes, such as accretion and collision.

The material that formed the primitive Earth was mainly the primordial material of the nebula disk, which was composed mainly of hydrogen and helium, which accounted for about ninety-eight percent of the total mass.

In addition, there is solid dust and material thrown out during the early shrinkage evolution phase of the sun.

In the process of the formation of the earth, due to the differentiation of matter, there are constantly light substances separated with volatile substances such as hydrogen and helium, and are carried to the outside of the solar system by the sun's light pressure and the materials thrown by the sun.

The other planets of the solar system, such as Mercury, Venus and Mars, are actually the same as the Earth, and because they are closer to the Sun, they may have formed in a similar way, and they retain more heavy matter, while the outer planets such as Jupiter and Saturn, because they are farther away from the Sun, still retain more light matter. Although there is still a great deal of speculation about the way of forming the primitive earth, most of the researchers' views and conclusions are relatively consistent, that is, after the formation of the above-mentioned nebula disk, due to the action of gravity and the instability of gravity, the material in the nebula disk, including the dust layer, due to collision accretion, formed many protoasteroids or stars, and then gradually evolved and gathered into planets, and the earth was born in it.

It is estimated that the time required for the formation of the Earth is about 10 million to 100 million years, and the formation time of planets (terrestrial planets) that are closer to the Sun is shorter, and the longer the formation time of planets farther away from the Sun, even up to hundreds of millions of years.

As for whether the primitive earth was hot or cold, scientists on the planet where birds don't also have different theories. Proceeding from the ancient theory of the origin of the earth, most people once believed that the earth was originally a molten body, and that the earth still retains its heat after billions of years of geological evolution. The results of modern research are more inclined to the theory of the origin of the earth's low temperatures. Whether the early state of the Earth was hot or cold is still debated. However, whether it is the theory of the origin of high temperature or the origin of low temperature, the earth has generally experienced a stage from heat to cold, and because the earth contains heat sources inside, this cooling process is extremely slow, and the earth is still in the process of continuing to cool.

When the earth was first formed, the temperature was relatively low and there was no layered structure, but later due to the bombardment of meteorites and other materials, radioactive decay and the gravitational contraction of the primitive earth, the temperature of the earth gradually increased, and finally became a viscous molten state. Under the rotation of the blazing fireball and the force of gravity, the material in the Earth's interior begins to diverge. Heavier material gradually gathers in the center of the earth to form the core, lighter material is suspended on the surface of the earth to form the crust, and material in between forms the mantle. This gives rise to the so-called layered structure.

In the early days of Earth's evolution, the primordial atmosphere escaped. However, as matter recombines and differentiates, various gases that were originally in the Earth's interior rise to the surface and become a new atmosphere. Due to the increase in the temperature of the earth's interior, the internal crystalline water is vaporized. Later, as the surface temperature gradually dropped, the gaseous water condensed, accumulated to a certain extent, and then fell back to the ground through rainfall, which lasted for a long time, so that a hydrosphere was formed on the ground.

The most primitive crust appeared about four billion years ago, and the Earth is bounded by its crustal appearance, which is called astronomical time before the appearance of the earth's crust, and enters the geological period after the appearance of the earth's crust.

As for what happened next, li and tiYes, are not very clear, after all, they are also only the pilots of spaceships, not scientists who specialize in the study of the earth.

It's just that looking at such a beautiful planet, it will become my hometown in a few years. Thinking about it, Li and Ti are still excited.

However, that was a few years later, and now the main thing is to deal with the impact of the spacecraft entering the Earth and rubbing against the atmosphere.

However, it has a very automatic operating system, in fact, as long as there are no accidents, all of this does not need to be operated manually.

Just when Li and Ti thought that everything was ready, they just waited quietly for the starship to safely penetrate the earth's atmosphere, but they didn't expect that an accident happened.

On the outskirts of the Earth's atmosphere, Ti and Li found massive objects that were pitch black and floating aimlessly.

At first, Ti and Li just thought that it was a huge rock left behind by a comet, after all, from what Li and Ti knew, the mechanical technology on the earth was not developed, which was equivalent to staying in a primitive society.

Therefore, even though these huge objects floating in the outer part of the Earth's atmosphere are somewhat suspicious, Li and Ti still do not attract enough attention.

Now, Li and Ti are just looking forward to the starship they are piloting to break through the Earth's atmosphere as soon as possible and reach the sky above the Earth to release special substances that hinder the development of Earth's biotechnology.

Unexpectedly, just as the starship piloted by Li and Ti entered the earth's atmosphere and resisted the huge friction generated by the surrounding starship and the atmosphere (due to the strong friction force, this is also the most dangerous moment that a spaceship can call during the voyage), from the surrounding aimless black huge objects drifting everywhere, a beam of lasers suddenly shot out!

"Warning! Warning! The black ship is under attack! The ship is under attack!"

The warning lights in the spacecraft were immediately lit, and the sound of sirens was also deafening.

Li and Ti were very confused, obviously judging from the information received from the main fleet, this earth obviously did not develop in terms of mechanical technology, but ......

Why?

The objects around here that can emit aurora lights are clearly the products that can only be produced when the mechanical technology civilization reaches the second stage?

Because, these things floating in the outer part of the earth's atmosphere are already perfectly in line with the second level of the requirements for judging the development of a civilization's mechanical technology!

Drop matter into space, attack, scout, and guard!

Although the starship that attacked Li and Ti in front of them was just a product of the second level of mechanical technology civilization, it was indeed much inferior to the bird not civilization that had reached the third level of mechanical technology civilization.

But......

Don't forget, the starship piloted by Li and Ti doesn't have any defense and attack systems installed at all!

Because it is necessary to put the material that can inhibit the development of the earth's civilization on the earth as soon as possible, speed must be an indispensable condition.

And in order to pursue the ultimate speed, the craftsmen of the Bird Don't civilization also dismantled all the attack and defense systems when modifying this starship with Li and Ti, and installed all the push launchers that can speed up.

Because, judging from the earth intelligence collected by the bird not civilization, even a starship without an attack and defense system can easily avoid the attack from the civilization on that earth with its perfect speed.

But......

What Li and Ti didn't expect was -

The information they gathered turned out to be wrong!

Earth, maybe it's the one who pretends to be a pig and eats a tiger!

Without any attack and defense system, the starship piloted by Li and Ti can only withstand all the attacks like a live target, the engine is destroyed, the cabin is cracked, and with thick black smoke, the starship also crashes towards Earth with the despair of Li and Ti.

And at the moment before the spaceship crashed, from the corner of Li's gaze, Mu Chen also seemed to catch a glimpse of the three fonts engraved on those black objects that emitted lasers—Qingfeng Sect.

"Qingfeng Sect?"

Could it be that the mysterious machinery that destroyed this starship was made by the Qingfeng Sect?

With the current doubts, Mu Chen also not only recalled the information he heard in the restaurant - the royal family tried their best to block the news of the ship's crash, so that the Qingfeng Sect did not move at all.

In fact, this may not be that the Qingfeng Sect did not know the news of the crash of this spaceship, but that as early as the outer atmosphere of the earth, the Qingfeng Sect discovered this spaceship that came to explore.

Since they have the ability to destroy this spaceship, they must have inspected this spaceship before these mysterious machines sent lasers to destroy it.

It was confirmed that there might not be any news on this spaceship that the Qingfeng Sect wanted, so the Qingfeng Sect ignored the information blockade of the royal family.

Indeed, even ordinary people witnessed the crash of the spaceship, and Qingyu, who has the cultivation of the Tribulation Period, how can he not perceive it?
