Sleeper

When the end comes and the world falls into eternal darkness, can you still find a reason to live? Lin Wanwan never thought that she would sleep in a metal coffin for seven full years. When she woke up in the dormant cabin of "Shelter Zero", she found that the world around her had changed beyond recognition. A thousand dormant cabins are empty. The former refugees either died of the sequelae of dormancy or disappeared into some unknown corner. She is the last survivor in this shelter. But what really shocked her was not the cruelty of the doomsday, but her own identity. She is "No. 001" - The only position reserved for "special personnel" in Vault Zero. What does that mean? Why was she chosen? What secrets does her missing mother hide?
