The 642nd Year After the Sun Went Out

The sun went out, and Earth entered its final days. Humanity built two enormous spaceships. One set off into space, while the other, due to energy shortages, was forced to remain on Earth forever.

Technology regressed, and the remaining energy was insufficient to keep everyone alive.

When Yin Yi woke up at the doomsday base, the squad she was in was about to leave on a death mission: transporting elderly survivors to the "graveyard."

I want to write hard science fiction, but I'm probably not good enough. I suspect I'll end up making it all up anyway QAQ.

It probably won't be very long. The whole story is already written, and I'll start posting once the backlog is ready.

Theme: To live or to die.
