No One Told Me to Save the World?

The devil came to this world 800 years ago, and the whole world was divided into two halves by the terrifying power of the devil. With the Abyssal Sea as the boundary, the feudal dynasty is in the east and steampunk is in the west. Two completely different civilizations. The pressure brought by the devil forced them to get mixed together. Everyone is looking for a way out. Immortal cultivators, demon hunters, seekers, demon-worshiping sects, progressive councils, and the royal family... All kinds of monsters and ghosts take turns to fight, and everyone wants to be the helmsman. The Demon Suppressor wants to put an end to the demons. The Puglieses, on the other hand, just want to escape. Just when the big ship of Daqian was getting more and more shaky, Qi Simiao came to this world. What does it mean that the world is about to end? What does it mean that I am the key to breaking the situation? No one told me that I should save the world?
