Exiled Right After Reuniting with My Family? I'll Build a Granary in the Northwest

[Lighthearted] [Male Rivals Competing for the Female Lead] A sunny, spirited heroine who grows stronger. Just after discovering she's the real heiress, Jiang Liuliu is exiled to the northwest? She can't help but cry, "Heavens, are you messing with me?" All you can eat in this yellow earth country is dirt? Wheat, potatoes, and corn can keep everyone fed. A drought disaster means starving to death? Early-ripening, drought-resistant oats, buckwheat, and broomcorn can save the day. Barren land can't grow roses? The hardy desert roses bloom with a fragrance that carries for miles. Medicinal herbs, cotton, melons, and fruit flourish everywhere, bringing prosperity to one and all. She only meant to help her family farm, but somehow romance keeps finding its way to her.

P.S. At first, Jiang Liuliu had a simple wish: she only wanted her family and herself to have enough to eat. Then she saw natural disasters and human calamities leave the land strewn with corpses. She thought that since she had come to this world, she ought to do something.
