The novel is about a pair of twin brothers who, because of a feud between two formidable martial artists, were separated at birth and raised on opposing sides.
Yaoyue refused to forgive Jiang Feng for scorning her and vowed to take revenge by making his sons destroy each other.
The other boy, known as Xiaoyu’er, is initially saved by his father's sworn brother, Yan Nantian, a powerful swordsman, but later falls into the hands of the Ten Great Villains, a group of notorious criminals in the jianghu.
Hua Wuque grows up to be a good-mannered, refined gentleman well-trained in the elegant martial arts of Yihua Palace.
During this time, he gets embroiled in complicated romantic relationships with various women, including Tie Xinlan, Su Ying and Zhang Jing.
The twins are initially hostile towards each other and have wildly different personalities; Hua Wuque is righteous, intelligent but naïve, while Xiaoyu’er is expedient, streetwise and cunning.
Determined to make the twins kill each other, Yaoyue eventually forces Hua Wuque to challenge Xiaoyu’er to a duel to the death.
Ho Che Wen created three comic series based on this story under the title The Impeccable Twins.
