At the moment it's only the beginning of the story and what's gonna happen in the future. The disaster we saw happen at the beginning of the manhwa is the disaster he will save the world from. At the moment he's in the past, aka we will have to wait for the disaster to happen in a far far away chapter.
Did I miss any chapters?? I been rereading the title and the manhwa too , so which part considered that he save the world?
