Exiled, I Empty the Imperial Palace to Raise an Enemy Prince

[Exile and Fleeing Famine + Female Transmigrates into a Book, Male Reborn + Stockpiling Space + Mutual Devotion + Both Powerful and Devoted] Yu Chengcheng transmigrates into a book and, from the start, her family is confiscated and she is exiled. No problem: she uses her pocket space to turn around and loot the imperial palace. On the road to exile, eight out of ten people die, and the journey is full of hardship and danger? Not a chance. Her group is strong and well-equipped, and their trip is safe and comfortable, like a vacation! She doesn't panic when they reach the northern frontier, either. She grows crops, builds cities, and develops tourism, gradually turning the place into a paradise. Only when the enemy kingdom's prince, a man with many secret identities, is on the verge of death after saving her does Yu Chengcheng discover that she was able to bring her space when she transmigrated into the book because he traded away his lifespan for it. Mu Yuntian: “It's the third life, and you finally didn't leave me behind.”
