Farewell to the Sky

An unprecedented super solar storm is about to hit the earth. The catastrophe will once again push mankind to the turning point of civilization. In the last three months of safe time, mankind has made a difficult decision: to carry out a self-salvation operation called "Farewell to the Sky" to collect and sort out all the wisdom and resources of human civilization so far. Some of them are stored in underground cities, and some are carried by spacecraft to the moon, where they will wait for the solar storm to completely subside before trying to return to the earth and repair their homeland. The duration of this process is unknown, its feasibility is unknown, and its success is uncertain. However, human beings will face disasters like their ancestors without flinching, move forward indomitably, and find hope in desperate situations!
