Shen Anan is wearing a book.
When someone else wears a book, they are either dressed as a domineering president, or they are the mother or daughter of a domineering president, and no matter how bad they are, they are the petite wife of a domineering president…
She is the only one who, in a false fairy tale, became the last mermaid on the verge of extinction.
In order to change the fate of the Little Mermaid’s complete extinction, the state encircled a small sea area for her and assigned her a national treasure-level scientist.
Ming is here to take care of her diet, but in fact, she is here to study how to breed her successfully.
Before the scientist came, Shen Anan swung the fish’s tail and vowed: “Mating? It doesn’t exist, I am a dignified human being. Even if I die, I can’t accept this kind of emotionless reproductive behavior.”
After the scientist came, Shen Anan: “I! Yes! Yes!”

Later, a group of photos was exposed on Weibo of the national treasure scientist Zhou Suiyu Wannian Changcao.
In the photo, Shen An’an swings a silver fish tail and frolics in the sunshine and blue waves. While licking the screen of Shen An’an’s prosperous beauty, netizens suddenly found that Shen An’an’s belly… It seems to be a drum?
For a while, the news of the successful breeding of the Little Mermaid quickly reached the top of the hot search.
Zhou Suiyu, the father of the child, posted a photo of the two and said, “What breeding? That is the crystallization of our love.”
Everyone: “…Excuse me, are such handsome scientists all assigned by the state? Where can I get them?”
