After Long Xiaoyang finishes his training and descends the mountain, he sets out to find his long-lost older sister. At the same time, he goes to the Su family of Yunzhou to marry the eldest daughter, as their marriage had been arranged when they were young. But the Su family's daughter has long been secretly in love with another young gentleman, and in the end she breaks off the engagement. What nobody else knows is that Long Xiaoyang is invincible in the martial arts, with no one who can stand against him.
Later, while searching for his sister, Long Xiaoyang becomes a constable and unwittingly gets caught up in a martial world feud.
Very good, without any fantastical or mystical elements.
