I Was Only Fleeing a Famine, So Why Does the Imperial Uncle Want to Marry Me?

[Transmigrating to farm + medical System + stockpiling supplies and fleeing famine + heartwarming + slow-burn + marriage first, love later + wife-chasing crematorium] Tang Xiaowei, a university student studying traditional Chinese medicine who had chewed on a little piece of jimsonweed stem, transmigrated! Her house was bare, her parents were dead, and she had a younger brother and sister to care for. As if that weren't enough, her awful aunt was scheming to take the family property! Tang Xiaowei, keep it together. You can do this! First, find a young man to marry and protect the family estate. Take on the troublemakers, sell medicinal herbs and braised meat, learn medicine, upgrade your medical space, and heal the sick. She soon had everything going her way... Then a terrible drought struck, and Tang Xiaowei stocked up on supplies and led the whole village to flee the famine... Once peace and prosperity returned, she arrived in the capital. Wait, why does the ruthless Regent from all those rumors look so much like her former husband, who left her a divorce agreement and disappeared without a word?
