Humanity is missing, luckily I have billions of clones.

Chapter 69 Original Ecology

Driven by the blazing flames, this rocket, powered purely by chemical fuel, began to accelerate violently.

In the Bluetuk settlement, Momorans looked at the bright sun in the sky with some awe.

Although the technology is very backward, so backward that it is like barbarians, and they still use chemical fuel rockets in this era, but...

It's a fucking wonder that a rocket this big can be built.

He inexplicably felt a sense of being like reading a history book and seeing that his ancestors had built giant buildings hundreds of meters high in an era when they didn't even have iron tools.

“This civilization… is full of weirdness.

With such backward technology, they were able to achieve deep space exploration by building such a large rocket;

It was clearly just a gunpowder gun, yet it was able to defeat our armed fleet;

So many people, yet they can cooperate so well and coordinate so well, and everyone gives their all without complaint. Is this a high level of civilization and unity?

The strangest thing is that everyone looks so similar, but you can't ask, and if you do, you'll be tortured. It seems that saying that they look similar is an offense to them. It's really strange..."

Momolance sighed softly and cautiously retreated into the residence assigned to him.

Now, he didn't think about anything else. He just wanted to cooperate as much as possible, suffer less torture, and live until the arrival of the main fleet of civilization.

Then I'll be free...

By then, I will definitely ask them again why they all look so similar, and see if they dare to torture me again...

……

In space, Li Qingsong stared solemnly at the giant rocket that was gradually moving away.

Amidst the intense combustion of liquid hydrogen and liquid oxygen, its speed has now reached more than ten kilometers per second relative to Roselle.

At the same time, more than 20,000 tons of fuel in the third-stage rocket have been consumed.

Separation!

With a single command, the third stage, comprising two-thirds of the rocket's length, immediately separated. The second stage then ignited, propelling the rocket, now significantly reduced in mass, to further accelerate.

Faster and faster, faster and faster.

After that, the second-stage rocket separated and the third-stage rocket ignited. Finally, the probe separated from the third-stage rocket and entered the inertial navigation state.

At this moment, its speed has reached an ultra-high speed that none of Li Qingsong's spacecraft has ever reached, reaching more than 80 kilometers per second!
Moreover, as it approaches the sun, its speed will continue to increase.

Because the process of approaching the sun can be compared to the process of a heavy object falling from a high place to the ground.

According to Li Qingsong's calculations, when the probe is closest to the sun, its speed will reach its highest, even exceeding 300 kilometers per second.

Yes, it does not fly directly to the earth, but first flies to the sun and accelerates during the process. After bypassing the sun, it slows down with the help of the sun's gravity before reaching the earth.

But... even at such a high speed, it will take about 6.5 years for the probe to reach Earth from Roselle.

It’s not that Li Qingsong doesn’t want to go faster, but he can’t.

Even the current speed is achieved by consuming tens of thousands of tons of fuel.

A super-giant rocket with a total mass of more than 70,000 tons only serves this probe with a mass of only five tons, and can only accelerate it to its current speed.

Among the five-ton probe, 4500 kg of its payload is also fuel, which is used to slow down when approaching the Earth. Otherwise, it will not be able to stay in the Earth's orbit.

In the end, the actual payload that reached the Earth was only 0.5 tons.

Pure chemical propulsion is such a waste.

But there was no other way. At this moment, Li Qingsong hadn't even mastered the secondary pressurization propulsion technology used by humans, let alone the high-speed ion propulsion used by the Bluetuk civilization.

At that moment, the tiny probe had already plunged into deep space, hurtling toward the sun. Aside from some data on coordinates and equipment status, Li Qingsong couldn't even use the probe's telescope to take in the distant scenery.

Because except for the most critical core equipment, all other equipment of this detector is in dormant state and not turned on.

They need energy to operate, electricity, and they need to generate electricity by burning fuel. But now, the 4.5 tons of fuel it carries is so precious that it cannot be moved lightly.

"Once we get closer to the sun, we can deploy solar panels and get electricity from the sun, and then the situation will be better."

Li Qingsong was thinking with a heavy heart.

Time passed quietly, and in the blink of an eye, several years had passed.

During this period, Li Qingsong has been doing reverse engineering work on the technological creations of the Bluetoke civilization. Although there are not many technologies that can be used now, there are still some.

Under Li Qingsong's various means, those captured Bluetuk people, even if they were unwilling or resentful, finally joined in the cause of promoting Li Qingsong's technological development and objectively contributed a lot.

As a result, the Luoshen base cluster has been in a state of rapid development, and the iteration of technology and equipment has never stopped.

At this time, the probe had flown over a distance of more than 10 billion kilometers, from the edge of the solar system to the interior of the solar system, approaching the outermost large planet, Neptune.

Here, the probe made its first orbital change, briefly started its propulsion, and turned on its camera for a while to record some images of Neptune.

Looking at the huge blue gas planet, Li Qingsong suddenly recalled the time when he passed by it on the Deep Space Spacecraft.

"Hello, Neptune."

At this moment, the speed of the probe has increased to 102 kilometers per second and is still increasing slowly.

After passing Neptune, the next planet we pass by is Jupiter.

At Jupiter, the probe briefly turned on again and then headed straight for the sun.

Finally, the probe passed by the sun at a distance of only 500 million kilometers.

After passing behind the sun, the probe began to slow down at full speed.

4.5 tons of fuel began to burn, generating hot gases, which pushed the small probe to slow down rapidly. Eventually, when the speed dropped to only 9.7 kilometers per second, it caught up with the Earth and entered the Earth's orbit.

After a long 14-hour delay, the command from Luoshen finally arrived.

The probe adjusted its posture and pointed its optical telescope at the Earth.

After the same long delay of more than ten hours, the signal from the detector was received by the giant antenna array and finally presented in front of Li Qingsong.

Li Qingsong saw the blue ocean, the lush forests, the green grasslands, and the desolate desert.

What appeared before him was an earth that seemed to have never been polluted or transformed by any intelligent creatures. It was a completely and utterly pristine earth.
