Under the strict surveillance of the quantum satellite, Yan Fei firmly grasped all movements within a radius of nearly eight light years centered on Earth. As soon as there's a stir within this range, the artificial intelligence "Dream" will immediately know and transmit the intelligence to Yan Fei.

In the universe one light year outside Earth, at a position 100 million kilometers from the outer edge of the Solar System's Oort Cloud, there was a quantum satellite launched by Yan Fei. This quantum satellite had been stationary for a long time, with its detection capabilities activated, scanning the starry sky within a radius of 100 billion kilometers and constantly monitoring all movements in this area.

In the surveillance of this quantum satellite, violent fluctuations began to occur in a space 50 million kilometers towards the direction of the Solar System, followed by the sudden emergence of a bizarrely-shaped space battleship from the void. It hovered in the cosmic vacuum, and then the spatial fluctuations disappeared.

As soon as this unknown space battleship appeared at a location 50 million kilometers from the Oort Cloud, it was detected by that quantum satellite, which immediately transmitted the intelligence to the drone carrier at the rear. Under the rapid transmission of the artificial intelligence "Dream," Yan Fei, who was still on Earth, quickly learned of this explosive intelligence.

But before Yan Fei could figure out how to respond to this sudden intelligence, that bizarrely-shaped space battleship somehow detected the quantum satellite 50 million kilometers behind it. Under Yan Fei's watchful eyes, that space battleship launched a missile-like object towards the quantum satellite. Just as this missile-like object was launched, it mysteriously disappeared. As Yan Fei was trying to track where the object had gone, he discovered violent fluctuations in the space near the quantum satellite, and that object suddenly popped out from the void, appearing near the quantum satellite.

Yan Fei knew something was wrong, realizing that the alien battleship intended to attack his quantum satellite. But once a quantum satellite becomes stationary, it can no longer increase speed to leave its original position. So when this suspected weapon approached his quantum satellite at an incredible speed, Yan Fei had no way to avoid this unknown object. As soon as the object neared the quantum satellite, a massive explosion occurred. But this explosion was completely different from an ordinary explosion because it didn't produce light and shock waves, nor energy waves, but instead caused violent gravitational disturbances.

In just an instant, the gravitational waves around the quantum satellite began to surge, suddenly increasing fiftyfold from the previous normal level. Under the influence of this abnormal gravity, Yan Fei's quantum satellite started falling towards the explosion's center. As it approached the explosion center, the shape of the quantum satellite began to change, gradually becoming more elongated, and in the end, it even looked like a noodle...

Yan Fei had just detected the abnormal gravitational waves nearby through this quantum satellite, and then he lost contact with that quantum satellite. He immediately realized that the weapon that had just exploded was likely a gravity bomb launched by the space battleship. This gravity bomb was mounted on a missile, which could engage in short-distance superluminal flight, thus destroying the quantum satellite 50 million kilometers away in less than ten seconds.

Witnessing all this unfold before his eyes, Yan Fei was profoundly shaken. He had a premonition earlier that great changes would occur on Earth, but he couldn't determine if the change was coming from deep space or within Earth itself. Now, after seeing the alien battleship, Yan Fei could finally confirm that the turmoil on Earth was from the aliens in deep space. These aliens harbored ill intentions towards the Solar System, otherwise, they wouldn't attack his satellite directly upon discovery.

From the moment the alien battleship suddenly popped out of the void to when Yan Fei lost the quantum satellite, less than a minute had passed. But in such a short time, Yan Fei gained a lot of useful intelligence. It revealed that the alien battleship was using the most common method in the universe: curvature navigation. Curvature navigation bends space, allowing the alien battleship to fly at an ultra-high speed that exceeds the speed of light many times over. Because the alien battleship was constantly in a state of space curvature, even the quantum satellites placed farther away by Yan Fei couldn't detect it, letting it break through layers of surveillance and enter the outskirts of the Solar System directly.

The alien battleship is only 50 million kilometers away from the Solar System's Oort Cloud Belt. If it continues with curvature navigation, it will enter the Oort Cloud Belt. Though the material in the Oort Cloud Belt is sparse, it is not a complete vacuum. It is filled with meteorites of various sizes and other celestial bodies. As soon as a curvature-navigating alien battleship encounters these meteorites and celestial bodies, regardless of how robust its hull is, it would immediately lead to the ship and its crew's destruction. Considering this safety issue, the alien battleship had to halt its curvature navigation and reveal its trace in the outskirts of the Solar System just before entering.

The missile carrying the gravity bomb, used by the alien battleship to attack the quantum satellite, should be a weapon-carrying platform capable of short-distance curvature navigation. It carries powerful weapons, enabling it to cross vast distances in a short time and attack distant enemies, making it impossible for them to dodge over long distances.
