Tan Tan is so old that she no longer knows her age, but she still looks like a fresh and young girl.
She thought, if a person is bored to the point of panic, why not find a really fresh and young girl to accompany her and raise those little monsters in "The Classic of Mountains and Seas"!
Lushu, Yi Zisun, a good and well-behaved little girl has grown the belly of many noble ladies in the capital...
PS. Two female protagonists, no cp, pure friendship.
