Firefly Afterglow

In the apocalypse, people always want to look for hope, but if there is really hope, is it still called the apocalypse? A seriously ill boy whose genes have been modified wakes up in the "Noah's Ark" where the rest of his life is at the end of the world. With his "reborn" body, he will explore the past of these hundreds of years. Was it a natural disaster that caused this situation? Or is it a man-made disaster? In the blank time, what has this world experienced? Raging alien beasts and indifferent people, what else is there to look forward to in this hopeless world? Let us use this weak firefly to light up this What a miserable world! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
