Doomsday and Ushering in a New Era

In this magical continent, it is just like our world, with flowers and trees, rare animals, treasures, and a legal system. Everything seems to be prosperous and developing in an orderly manner. What is so strange about such a normal continent? It is strange that there will be a catastrophe in this world every ten thousand years or so, and there is no sign of this catastrophe, so that each catastrophe will last until it causes the extinction of human civilization before it slowly subsides. What keeps them repeating themselves in destruction and prosperity... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
