Can you recommend a novel about a man who is betrayed by a woman and exiled to a city where superpowered people live?

There were monsters in that city, similar to magical beasts. It was very difficult for humans to survive the winter in that city. The male lead was practicing his superpower with a little girl. The first time they met, the girl seemed to be smoking. That city was actually a prison. The male protagonist wanted to cultivate and take revenge on the woman who betrayed him. The girl had a powerful mother who was also one of the main characters. There were also robots and whatnot. He had forgotten the names of the characters inside.
