After hearing Sun Longyu, the ground commander, Zhao Yunlei furrowed his brow and pondered, desperately trying to recall the sound he had just heard.
He tried bit by bit to express the sound he had heard.
"Thud... thud-thud... clang-clang. No, it should be thud-thud, jingle-jingle..."
After the ground command center simulated the sound he described, Zhao Yunlei realized upon hearing it that it still differed somewhat from the sound he had heard.
Afterward, they fine-tuned the sound countless times based on Zhao Yunlei's description, but no matter how they adjusted it, they could not reproduce the sound he had just heard.
In the end, everyone had no choice but to give up.
Sun Longyu, the head of the command center, organized the details of the incident into a report and submitted it to his superiors.
As a high-ranking member of the empire, Sun Longyu knew some secrets—namely, that aliens truly existed.
Furthermore, there were some aliens on Yanhuang Star. However, given his rank, that was all he was allowed to know.
As for what the aliens actually looked like, he knew nothing at all.
Now that they had discovered something suspected to be an extraterrestrial civilization in space, they had no way to confirm it, but they still had to submit the matter for the higher-ups to decide.
After his superiors received the report and saw that it was related to an extraterrestrial civilization, they did not dare delay and hurriedly passed it on to the imperial secretariat.
Before long, Secretary Yuan Lan received the submitted report.
After reading its contents, Yuan Lan could not help frowning. "An astronaut heard a mysterious entity outside the spacecraft knocking on it in space. Is this suspected to be an incident involving an extraterrestrial civilization?"
As the imperial secretary-general, she stood below only one person yet above countless others. Over the years, she had come into contact with far too many secrets.
For example, Du Kao and his group, the extraterrestrial corpse preserved within the Imperial Academy of Sciences, the Empress being a female angel, and information about various civilizations in the universe, among other things.
Star Palace.
"Your Majesty, a report just came from the Yan Chen Aerospace Command Center. It says they may have encountered an extraterrestrial civilization in space."
After arriving beside Ye Chen, Yuan Lan spoke softly.
Hearing this, Ye Chen raised his brows. "An extraterrestrial civilization?!"
Ye Chen took the report from Yuan Lan and quickly read it from beginning to end.
Afterward, Ye Chen fell into deep thought. "Could this really be some civilization from the universe? That shouldn't be possible. Could it be the butterfly effect caused by me?!"
At that thought, Ye Chen felt a toothache coming on. The plot had already collapsed into complete nonsense, so nothing that appeared in the future should surprise him anymore.
Ye Chen then instructed the aerospace center to continue following up on the matter.
At the same time, his figure arrived in space, where he used the planet's gravity to envelop himself.
In the end, he vanished completely, leaving behind only an insignificant fragment of a tiny meteorite.
This was one of the applications of planetary gravity he had developed over the years.
His ability to control planetary gravity came from the stellar core within his body, while a stellar core was the essence left behind after a planet shattered.
In essence, Ye Chen was practically a half-humanoid celestial body.
After flying a distance away from the Soaring Dragon One spacecraft, Ye Chen simply watched in silence.
He planned to stay here for the next few days. He wanted to see whether this incident truly had anything to do with an extraterrestrial civilization.
During the remaining mission period, day and night alternated, while that sound suddenly rang in Zhao Yunlei's ears from time to time, regardless of whether it was day or night.
Every time he heard the sound, Zhao Yunlei immediately went to the observation window and looked outside. He wanted to find the unknown entity knocking on the spacecraft.
However, that unknown entity seemed exceptionally mischievous. It kept playing hide-and-seek with him, making it impossible for him to find it.
Yet, just as Zhao Yunlei completed his final orbit and was preparing to return, the corner of his eye suddenly caught a black shadow flashing past the observation window. Zhao Yunlei instinctively looked over, but there was nothing there.
Zhao Yunlei hurriedly accessed the spacecraft's recorder and located the footage from moments earlier. Sure enough, the recorder showed something black suddenly flashing past the observation window.
It was just that the spacecraft was currently in a backlit position. Without checking the recorder, it would have been very easy to miss.
Even so, because that thing had been moving too quickly and vanished in an instant, the image displayed on the recorder was extremely blurry.
The black shadow had practically merged with the darkness of night. Seeing this, Zhao Yunlei could not help frowning.
With footage like this, he simply could not determine what the thing actually was.
"What exactly is this? Was it a meteor drifting past?
"Or is there really some extraterrestrial life-form outside? But if it's a living thing, how could it survive?
"After all, this is space, with not a trace of air and a harsh temperature of minus 270 degrees Celsius."
Looking at the object on the screen, Zhao Yunlei's mind raced through all kinds of guesses.
Of course, he believed that this thing was probably the extraterrestrial life-form that had knocked on his spacecraft.
In recent years, extraterrestrial phenomena had become popular throughout society, so Zhao Yunlei had also imagined whether there might really be some extraterrestrial life-forms in space.
But whenever he remembered that this was outer space, he dared not believe it.
After all, such a guess was too absurd. Aliens existed only in movies.
Leaning against the observation window, Zhao Yunlei remained unwilling to give up and watched for a while longer. After waiting more than ten minutes, he still saw no sign of any living creature.
He shook his head with a self-mocking smile. He had really let his imagination run away with him to believe in aliens.
He then prepared to return.
As the spacecraft departed and plunged toward Yanhuang Star.
A while later, a mechanical life-form resembling a rat, its body battered and tattered, suddenly appeared at the spacecraft's former location.
Its red eyes were wide open as it watched the fireball below descend toward Yanhuang Star.
"Bzzzt!!"
In the 5201st Azure Feather Year of the Azure Feather Civilization, the ZS3846 Purple Rat probe robot discovered a low-level civilization in the T87335 star system, named the Yanhuang Civilization. Recording.
As the red eyes of the ZS3846 robot flickered faintly, streams of information were stored in its internal database.
The probe robot "Purple Rat" then flew into the distance, circling Yanhuang Star.
At the same time, its outer body continuously absorbed sunlight from its surroundings.
The Purple Rat had adjusted itself to low-energy endurance mode according to the circumstances.
In the next moment, a huge hand suddenly appeared in front of the Purple Rat and instantly seized its body.
Looking at the struggling "Purple Rat" in his hand, Ye Chen was speechless.
"Well, damn. There really is an extraterrestrial civilization. It looks like a probe AI robot, but I wonder whether this thing sent Yanhuang Star's coordinates out."
Warning! Warning!! A high-intensity gravitational restraint has been detected. Antimatter engine activating. Energy supply in progress. A high-energy life-form has been detected. Assessing danger level. Danger level: 100%. Escape mode initiated. Warning! Warning!! Escape failed. Initiating system self-destruct mode.
Ye Chen: "..."
Feeling the lethal threat coming from his hand, Ye Chen's hair stood on end.
"Damn it, this little thing isn't planning to blow itself up, is it? It can't be, right?!"
It had been less than a second since he grabbed the little thing, yet he already felt that the tiny rat had transformed into a super bomb.
At that moment, he was utterly speechless. He had never expected this extraterrestrial civilization to be so decisive that it would not even give him a chance to communicate.
Ye Chen immediately hurled the little rat away with all his strength.
"Boom!!"
A few seconds later, the people on the side of Yanhuang Star plunged into night saw a sun appear in the sky.
Yanhuang Star, outer space.
After throwing the thing away, Ye Chen had wanted to flee, but he soon felt a powerful shock wave rushing toward him.
Immediately afterward, the shock wave sent his body hurtling toward Yanhuang Star's satellite, the "Moon."
