I Can Bear All the Troubles in the Heavens Alone?

My name is Gu Fan, an ordinary library administrator. I have no system and cannot practice, but I have a magical power that is "unrivaled in the world" - all natural disasters, man-made disasters, killings, and bad luck in this world will automatically turn around before they happen and be carried by me alone. In order to survive these endless disasters, I was forced to live again and again.
