Western Fantasy: the Princess Wants to Save the World

Hecilia is wearing a book. It's different from other time travellers. The system told Hecilia that the continent called Svest would be destroyed within three years. If she can save this continent, not only can she return to her own world, but she can also get 10 billion. After it announced the mission, it had no hope that Hecilia could complete the mission, and even kindly reminded her that she might as well enjoy this world for three years. But it forgot that this was the second time it had dragged Hecilia into this continent.
