One Piece: I'm Destined to Be the Son-in-Law King! - Chapter 23: Mutual Appreciation

He was The Greatest Talent in the Nine Hells Realm.

Shen Zhenyi began to practice his sword when he was four years and two months old.

At the age of seven, he studied the Ten Thousand Sword Sutra. By the age of eleven, he fought against the Yudao in Shangqing Palace. In an instant, he unleashed one hundred and eighty-five sword strikes, making it impossible for anyone to retaliate. The Yudao admitted defeat and deemed him as “The Peerless Genius.”

At the age of 14, Shen Zhenyi, with his Six Forms of the Ancient Sword, surpassed the swordsman Zuo Tianxing who was ranked among the top ten masters in the world, and won the title of “The First Swordsman of the Abyss.”

He now lies crippled. A fraction of the state he was in before. Or so they thought.

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.
