MTL - Little Mermaid Dressed As a Scientist - Chapter 63

After rebirth, she, who used to be a top international spy, becomes the eldest daughter of the Fengs, a fat girl who is ugly and foolish in the eyes of the ordinary people.
Mastering Royal 18 Saber Moves and Purgatory 9 Palms, she rose to fame with the martial arts of Demon Cook.
Upon an imperial edict, she was ennobled as the wife of Lord Cen, and then suffered various intrigues and plots…
She proved herself to be a real overmatch and a true genius to the world…

This is the love story of the 2nd brother of the Dragon Family. He is one of the most successful businessman in the capital and one of the Emperor’s favourites – he is the most eligible bachelor in the capital and every lady in town wants to marry him.

The story starts with the female lead, Ju Mu Er, a blind teacher of guzheng, who goes to pay a visit to Long Yue to ask him to build an awning on his popular business street so her friend, a flower seller, will not get wet and fall sick. Long Yue laughs at her (because he loves money and is calculative) and she makes a bet with him that she can allow him to escape from a pesky female suitor without making it obvious.

She successfully wins the bet and from then on, Long Yue constantly makes her life a trouble (since she costs him so much money)…. not realizing he is slowly falling for her.
