I'm the Ancestor of a Top-Tier Star [Metaphysics]

Tan Banqing was badly injured and hadn't fully recovered. She turned back into the body of a six-year-old girl, and with nothing else to do, she was advised by her juniors, all of whom had graying beards, to go out and see the world. A lot had changed. Afraid she wouldn't feel like moving, someone said that a younger member of the family was having a bit of trouble and asked their ancestor to look after him. Tan Banqing thought it over. How was she supposed to take care of a twenty-year-old kid? Shi Xuan looked at the little girl who barely came up to his thigh and fell silent. You mean she's my ancestor??? Tan Banqing rubbed her temples, thinking that looking after a child was such a hassle. Forget it, she'd just give him whatever he wanted. Shi Xuan rubbed her temples, thinking that little kids were so hard to look after. Whatever she lacked, she'd make sure she had. Shi Xuan said she wanted to shoot a creepy-style music video, so Tan Banqing brought in a whole bunch of nonhumans as extras. Shi Xuan said she'd been having bad luck lately, so Tan Banqing went straight to the culprit's home. Tan Banqing said she'd never been to an amusement park, so Shi Xuan took her there without a second thought. Tan Banqing said she'd never tried much good food, so Shi Xuan put on sunglasses and a hat and took her to the food street. Tan Banqing: Sigh, poor kid. She can't do anything. Shi Xuan: Sigh, poor great-grandma. She's never gotten to have any fun. Great-grandma aged one year every month. Later, she grew up. And she brought his nemesis right in front of him. Nemesis: Call me Great-Grandpa. Shi Xuan, visibly exasperated: Get lost!!! 1. The male lead is someone else. 2. The female lead starts out as a child and will grow up. 3. A story about the supernatural. Theme: Go outside more, walk and exercise, and enjoy a richer, more beautiful life.
