Shengshi is a cute little girl. The little girl is not like ordinary girls. She doesn't like to follow TV dramas and star-studying, and she doesn't like Obama. What Shengshi likes is archeology, dinosaurs, biological records or unsolved mysteries of cosmology.
Sheng Shi has never been in love since she was a child. This does not mean that Sheng Shi is ugly. Although she is not a glamorous girl, Sheng Shi is a cute and delicate girl. Even when she was fat, she was still fat and cute.
There were people in elementary school, middle school, high school and college who pursued the little girl, but for some reason, the little girl didn't agree.

Until one day, the little girl met a spherical system that said she came from the Space Bureau's Time Travel Department, and she started a magical journey.
