My Lord, the Silly Fat Daughter Is Actually a Master.

She is the only legitimate daughter in the palace of a minister, but her mother died young and her father does not love her. Because she had been stupid and fat since she was a child, and in order not to be consumed by food, Zha's father thought her grandma was keeping vigil and sent her to her hometown on the border to ignore her. During the wake, the more than 200-year-old ancestor of the royal family accidentally noticed her body and wanted to take her body away. Fortunately, she was lucky in the process. The old man burped at the critical moment, so she pretended to be the royal ancestor and started to walk on the road as the ancestor!
