Break Out of the Earth

One day in twenty years, a dark red star will hit the earth. It's called the Blood Star, with a diameter of ten kilometers, enough to end most lives. Nuclear bombs, impactors, and laser arrays all failed to intercept, and mankind entered the Ark Age. Humanity formed a coalition government and began to build a seed fleet: 63 spaceships, 80,000 people and genetic backups of all species on the earth, flying to the new soil 4.24 Light-years away at 0.15 Times the speed of light. The voyage lasts thirty years: those who board the ship will die in the ship, and their descendants will arrive in their new home. For the first time, mankind is forced to answer: Who deserves to live? The day the boarding plan was announced, no one was satisfied. The secretary-general gave up his qualifications, and the deputy director advocated taking away only useful people. The old welder was carried by the crowd and squeezed onto the gangway welded by himself. The designer waited for his name the night before boarding the ship. The order collapsed into "leave if you can", and 120,000 people crowded onto the ship with a designed capacity of 80,000. 63 Ships ignited and left the earth's orbit, and the blue and white planet behind them slowly shrank - the entire story of eight billion people, only a quiet figure remained. But the story doesn't end at the moment of setting sail. Thirty years of deep space night: children who have never seen the earth, the "stop faction" who were shattered by one frame of image, the genetic drift of the micro-ecosystem, and the fear of losing contact for six hours. Two hundred thousand people not only have to survive, but they have to start all over again once they arrive.
