Cosmic Echo

Humanity has achieved controllable nuclear fusion and entered a first-level civilization, but it has fallen into internal friction due to public and private ownership of energy. Lin Yan loves the stars deeply, but due to academic credits, he failed to enter the astronomy department and became an AI engineer. He built a private observation station in a corner of the city to monitor deep space alone. A strange beast-like roar was captured by AI. It was definitely not any known celestial phenomenon. He restored the outline of an alien orc through modeling, but the authoritative organization downplayed it and classified it as supernova radiation. Until an alert came from the orbit of Jupiter: the alien fleet outpost has entered the solar system. Humanity hastily responded to the challenge, using lasers, microwaves, and space battleships, but they could not even break through the opponent's shield. Conventional weapons are completely ineffective and civilization is on the verge of destruction. In a desperate situation, Lin Yan's military academy made a small effort to overcome public opinion: the previous generation of inhuman weapons used nuclear fission, and this generation will use nuclear fusion to create artificial black holes. Alien civilizations rush into black holes arrogantly, thinking that it is the end of nothingness. They don't know that black holes don't lead to other worlds, they only squeeze and reborn inside at extremely high speeds. When everything calmed down, the solar system ushered in the second sun. Destruction is always the rebirth of stars.
