Humanity is missing, luckily I have billions of clones.

Chapter 57 Ion Propulsion
This detector uses Li Qingsong's most advanced stealth technology: it is not only as small as possible, but also painted black, and the surface is coated with a layer of stealth material to avoid being scanned by radar waves as much as possible.

At the same time, the orbit preset by Li Qingsong for it will not approach the enemy planet, but will pass by it at a high speed about 100 million kilometers away.

So, after a combat spacecraft is accelerated to a certain speed and the orbit is suitable, it is "thrown" out.

After that, it will continue to fly along its current orbit.

During this process, it will always keep in touch with the deep space communication network built by Li Qingsong, constantly obtain its relative position information, correct its orbit, change orbit, etc.

At this moment, its speed has reached about 12 kilometers per second.

It will follow a parabolic orbit with a slight arc, taking about 40 days and traveling about 4200 million kilometers to eventually reach the closest point with Enemy, and observe Enemy during the process.

This is not the only probe launched by Li Qingsong.

Behind it, more than a hundred probes were launched one after another. If necessary, Li Qingsong could launch more at any time.

While waiting for the probe to reach its destination, Li Qingsong was not idle, but continued to work hard on war preparations, including stockpiling supplies, producing clones, and producing spacecraft.

Time passed quietly.

As the distance gets closer, the probe gradually gains a clearer observation field of view than a space telescope.

Then this faint light spot gradually took on a disc-shaped structure, with vaguely visible undulating gullies and a dark red surface.

This is a planet roughly similar to Roselle, with a similar formation time and elemental structure, and almost at the same time - about 45 billion years ago, both were "thrown out" by the gravitational battles of the large planets in the early inner solar system, and have orbits so far away from the sun.

But now is not the time for scientific research.

Li Qingsong only recorded these data temporarily and did not spare any energy to analyze them.

He has been trying his best to search for traces of intelligent life on the enemy planet.

When the distance was about 1000 million kilometers and there were 10 days left in the voyage, Li Qingsong finally made his first discovery.

The probe observed a bright spot around the enemy planet.

The bright spot is roughly strip-shaped and is rotating around the enemy planet.

It appears to be a spaceship.

After a simple conversion based on the ratio, Li Qingsong obtained an extremely astonishing data.

The length of this spaceship is at least five kilometers!
A five-kilometer-long spaceship!
Not to mention a five-kilometer-long spacecraft, even a space laboratory could only be built with all our efforts, which was more than 1000 meters long.

How advanced must the technological capabilities of a civilization be to be able to build a spacecraft five kilometers long?

This has even far surpassed human civilization at its peak!
Li Qingsong's heart began to sink slowly.

Such an enemy is definitely not someone I can fight against.

But... why did they just lure the strange bird here instead of doing it themselves?
It's been so long, why haven't they called me directly?

There must be a reason for this!

Li Qingsong did not despair, but continued to carefully control the detector and slowly approached it.

When the distance was shortened to about 500 million kilometers, Li Qingsong could roughly see the shape of the spacecraft. Its shape was similar to his own space laboratory, with a main axis and some rings.

However, it is much larger than his own space laboratory, and it is obviously self-powered. There are several huge structures on it that are obviously thrusters. Unlike the space laboratory, it cannot move at all.

It's just... it seems a little damaged? Some structure seems to be missing in the middle? Like it's been through an explosion?
The distance was too far and Li Qingsong couldn't see clearly.

But he did see something else.

A cluster of artificial buildings had clearly appeared on the surface of Enemy. These massive structures had smooth, shiny exteriors, interspersed with lights, making them sparkle like gemstones.

According to Li Qingsong's estimate, its overall size is about 20 square kilometers.

"The base isn't that big..."

The probe continued to approach and came to a distance of only 200 million kilometers from it.

At this time, Li Qingsong was able to confirm that the spacecraft was indeed damaged, and the base belonging to these unknown intelligent life forms on the enemy planet was indeed only about 20 square kilometers.

In addition, Li Qingsong also saw some smaller spots of light around the huge spaceship.

During the time that Li Qingsong observed, those light spots sometimes surrounded the large spaceship, sometimes moved away, and sometimes landed on the surface, as if they were small spaceships on missions.

There are not many small spaceships, only about 40.

but……

At this moment, they seem to be performing some special actions.

Li Qingsong saw that they all took off from the surface and gathered around the huge spaceship.

After a period of silence, about 30 of the spacecraft began to act in unison, flying in the direction away from the enemy planet.

Bright but not thick tail flames appeared at their tails, which were completely different from the gas tail flames ejected by their own spacecraft burning methane and oxygen.

Propelled by these tail flames, the speed of these spacecraft increased rapidly.

Li Qingsong felt that the shape and color of the tail flame were somewhat familiar.

After recalling for half a second, Li Qingsong suddenly remembered that the tail flame of the Deep Space spacecraft, which used high-pressure jet technology as its propulsion power source, was surprisingly similar in shape to this tail flame!
The propulsion principle of the Deep Space spacecraft is to burn liquid hydrogen and liquid oxygen to generate high-temperature gases, and then heat these high-temperature and high-pressure gases a second time through the onboard fission reactor, raising their temperature to tens of thousands of degrees Celsius, causing the pressure to rise sharply, allowing these gases to be ejected at a speed far exceeding normal combustion, while obtaining greater thrust while saving working fluid, so as to complete the interstellar voyage to Roselle.

But it is obvious that the propulsion technology used by these spacecraft at this moment is more advanced than that of the deep space spacecraft!

This technology seems to have always existed in human dreams, but has never been realized... high-power ion propulsion technology?!

Li Qingsong was shocked.

But what shocked Li Qingsong even more was the next moment.

He saw that the acceleration direction of those spaceships was exactly where he was, Luoshen Star!
They were coming towards him!

The next moment, perhaps due to some kind of attack or electromagnetic interference, the detector instantly lost contact with Li Qingsong.
