Edge of Stars

Twenty years ago, a spacecraft was wiped out deep in the universe. The moment the information was transmitted back, mankind knew for the first time: It turns out that in the universe, you can be killed by something "passing by" without the other party even noticing you. Chen Yuanshan is dead. Before he died, he left half a sentence. No one knows what that half sentence is. Later, his son received a letter of appointment as captain. He has never been on any actual combat mission, and no one on the ship obeys him. But he said he wanted to go to that restricted area and listen to that half-sentence. Someone asked: Can you come back if you go? He said: I don't know. Then why did you go? He looked out the window in the direction where his father disappeared. "He went to see it for mankind," he said, "I went to hear it for him." What lies ahead is unknown. Behind them are unfinished last words.
