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 that Li Qingsong preset for it is not to get close to the enemy planet, but to pass by it at a high speed about 1 million kilometers away. So, after a fighter spacecraft accelerated to a certain speed and reached a suitable orbit, it was "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 own 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 slightly parabolic orbit, taking about 40 days and traveling about 42 million kilometers to eventually reach the closest point to Enemy Planet, and observe Enemy Planet 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. During the time of waiting for the probe to reach its destination, Li Qingsong was not idle, but continued to carry out war preparations with all his strength, including storing supplies, producing clones, and producing spacecraft.
Time passes quietly. As the distance gets closer, the probe gradually gains a clearer field of view than a space telescope. Then this faint light spot gradually took on a disc-shaped structure, and the undulating gullies and dark red surface could be vaguely seen on it. This is a planet roughly similar to Roselle, with a similar formation time and elemental structure, and at about the same time - both were "thrown out" by the gravitational battles between the large planets in the early inner solar system about billion years ago, and have orbits so far away from the sun. But now is not the time to do scientific research. Li Qingsong only recorded these data temporarily and did not spare the 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 shortened to about 10 million kilometers and there were 10 days left in the voyage, Li Qingsong finally made his first discovery. Around the planet Enemy, the probe observed a bright spot. 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 for a space laboratory, even with all their efforts, they could only build one that was more than 1,000 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 the peak period of human civilization! 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 to them instead of doing it themselves? It's been so long, why haven't they called 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 5 million kilometers, Li Qingsong could roughly see the appearance of the spacecraft. Its appearance is roughly the same as that of its own space laboratory, with a main axis and some rings. However, it is much larger than his 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? There seems to be some missing structure in the middle? Like it experienced an explosion? The distance was too far and Li Qingsong couldn't see clearly. But he did see something else. It was obvious that there was a community of artificial buildings on the surface of Enemy Star. Those huge buildings had smooth and bright surfaces, with some lights in the middle, making them look as dazzling as gems. 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 2 million kilometers. At this time, Li Qingsong was able to confirm that the spaceship was indeed damaged, and that 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 some 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 spaceships began to act in unison, flying in the direction away from the enemy planet. Bright but not thick flames appeared at their tails, which were completely different from the gas 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, thereby 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 direction in which those spaceships were accelerating was exactly the Luoshen Star where he was! 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.
