Plot
Eighteen years ago, a handsome martial artist, Jiang Feng, was injured in a fight and coincidentally saved by the sisters Yaoyue and Lianxing of Yihua Palace, one of the deadliest martial arts clans in the jianghu (martial artists' community). Yaoyue fell in love with Jiang Feng, but he rejected her despite her beauty because her arrogance put him off. He fell in love with the sisters' servant, Hua Yuenu, impregnated her and fled with her. Jiang Feng's jealous servant, Jiang Biehe, betrayed his master and caused a group of bandits to attack Jiang Feng and Hua Yuenu shortly after Hua had just given birth to a pair of twin boys.

Although Jiang Feng and Hua Yuenu died, their sons were unharmed and discovered by Yaoyue and Lianxing. Yaoyue refused to forgive Jiang Feng for scorning her and vowed to take revenge by making his sons destroy each other. The sisters then adopt one of the boys, whom they name Hua Wuque. 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. However, the Villains did not harm Xiaoyu’er and instead decide to raise him and train him to become the greatest villain in the history of the jianghu.

Hua Wuque grows up to be a good-mannered, refined gentleman well-trained in the elegant martial arts of Yihua Palace. On the other hand, Xiaoyu’er is trained by the Ten Great Villains in a wide range of not-so-powerful martial arts and other skills such as theft, deception, the use of poison, and the art of disguise. Once he is old enough, the streetwise Xiaoyu’er ventures out into the jianghu alone and relies on his wits and skills on a series of adventures. During this time, he gets embroiled in complicated romantic relationships with various women, including Tie Xinlan, Su Ying and Zhang Jing.

In the meantime, Yaoyue sends Hua Wuque to kill Xiaoyu’er, lying to him that Xiaoyu’er poses a dangerous threat to them. Against the backdrop of various escapades, the twins come to blows several times. Each of their encounters follows the same pattern. Hua Wuque is more powerful in martial arts than Xiaoyu’er, but the latter always manages to survive by using his wits to escape from the former. 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. However, they gradually develop mutual respect and become friends after braving danger together. At the same time, they become entangled in a love triangle with Tie Xinlan.

Determined to make the twins kill each other, Yaoyue eventually forces Hua Wuque to challenge Xiaoyu’er to a duel to the death. After Xiaoyu’er is apparently killed by Hua Wuque during the duel, Yaoyue reveals the truth to Hua Wuque and tells him about her plan to make their father pay the ultimate price for scorning her. Hua Wuque is horrified after learning the truth and realising that Xiaoyu’er is actually his twin brother. Just then, Xiaoyu’er comes back to life, having feigned death earlier by consuming a special drug. The twins finally recognise and acknowledge each other as brothers, thus putting an end to Yaoyue's evil plan and ending the story on a happy note.

Main characters

 * Xiaoyu'er, born Jiang Xiaoyu , is Jiang Feng and Hua Yuenu's son. He was raised by five of the Ten Great Villains and trained to become a great villain. Though his body is covered in scars due to his brutal upbringing, he possesses considerable charm and rugged good looks, which allow him to leave a lasting impression on every woman he meets. Although a respectable fighter, Xiaoyu’er prefers to rely on his intelligence, cunning, and a variety of skills such as thievery and deception to overcome challenges. However, when he encounters Hua Wuque, he realises that he cannot rely on tricks alone to stay alive, so he starts honing his fighting skills and ultimately turns into a formidable martial artist in his own right. Although his tough upbringing causes him to adopt a callous, hedonistic persona in public, he has a strong moral compass and is naturally kind and protective of others.
 * Hua Wuque is Xiaoyu’er's fraternal twin brother, and the heir to Yihua Palace and its only male resident. Bearing a striking resemblance to his father, he looks extraordinarily handsome and has a more androgynous appearance compared to his brother. He is highly respected in the jianghu for his formidable prowess in martial arts and his gentlemanly, graceful manners. However, he has a tendency to suppress his emotions and has a naive outlook towards life.
 * Tie Xinlan is Tie Zhan's daughter. Although she has a beautiful appearance and seems soft-hearted, she is actually strong-willed, brash and extremely stubborn. A decently good fighter, she has been trained by her father to use the "Berserk Hundred Hits" . She falls madly in love with Xiaoyu’er even though he initially treats her badly. She later falls in love with Hua Wuque, who has strong feelings for her. This results in her becoming entangled in a love triangle between the brothers, and she often has to intervene to prevent them from fighting.
 * Su Ying is Wei Wuya's foster daughter. Spoiled, arrogant, scheming and anti-social, she is well-versed in medicine and extremely cunning but quite mediocre in martial arts. Her intelligence enables her to manipulate many martial artists, while her beautiful appearance and indifferent personality are similar to those of Yaoyue and Lianxing – which was why Wei Wuya adopted her. When she meets Xiaoyu’er, she falls in love with him and decides to follow him until she wins his heart. She is more intelligent than him and knows how to bend him to her will.
 * Yan Nantian, nicknamed "Best Divine Swordsman Under Heaven" , is Jiang Feng's sworn brother and one of the most powerful martial artists in the novel. His prowess in swordplay is unmatched in the jianghu and his "swordsman aura" can be even felt from a distance. Massive in stature and dressed like a pauper, he is so powerful that he can shave a man bald in a single sword movement without the man noticing it. After he is ambushed and knocked unconscious by the Ten Great Villains, he is revived by Wan Chunliu, who kept him alive under the pretext of using his comatose body to test new drugs. When he regains consciousness, he realises that he has lost his prowess in martial arts, so he trains for many months to regain his powers and eventually surpasses his original self. He serves as Xiaoyu’er's role model and trains him in martial arts.
 * Lu Zhongyuan, nicknamed "Great Hero of the Southern Sky" , is Yan Nantian's close friend and one of the most powerful martial artists in the novel. In his prime, he had defeated Du Sha before but had lost to Wei Wuya and had disappeared from the jianghu for several years before reemerging. He dies after falling into a trap set by Jiang Yulang.
 * Jiang Feng, nicknamed "Yulang" was Xiaoyu’er and Hua Wuque's father. He met Hua Yuenu of Yihua Palace, fell in love with her and eventually eloped with her. He committed suicide to join his wife after she was killed.

Yihua Palace

 * Yao Yue is the first mistress of Yihua Palace and a formidable martial artist. Although she possesses beauty, charisma and skill, she is described by Jiang Feng as "not a living person or human being, but fire, a block, ice or a sword instead". Jiang Feng rejects her and elopes with Hua Yuenu. Angered, Yaoyue pursues and hunts down the couple. After Jiang Feng and Hua Yuenu die, Yaoyue intends to kill their twin boys but Lianxing stops her. The sisters choose one of the twins and raise him as their son and groom him to be the heir to Yihua Palace.
 * Lian Xing is the second mistress of Yihua Palace and Yaoyue's younger sister. She is described to be a sweet and pretty woman whose beauty surpasses that of a flower blooming in spring. According to Xiaoyue'er, in comparison to Yaoyue, Lianxing is warmer in character than her sister. This is confirmed by Tie Pinggu, because Lianxing, like Yaoyue, had also fallen in love with Jiang Feng, but was afraid to express her feelings for fear of her sister. After Jiang Feng and Hua Yuenu die, Lianxing saves the twins by suggesting to make them kill each other when they are grown up instead of killing them now. Throughout the novel, it is hinted that Lianxing, unlike Yaoyue, does not take the revenge plot seriously. Hua Wuque sees Lianxing as a mother-figure and treats her with love and respect. Compared with Yaoyue and Yan Nantian, Lianxing is slightly weaker in martial arts than her sister, but equal to Yan Nantian.
 * Hua Yuenu was a servant of Yihua Palace. She met Jiang Feng by chance, fell in love with him, and eventually eloped with him. She was killed shortly after giving birth to Xiaoyu’er and Hua Wuque.
 * Tie Pinggu is a servant of Yihua Palace who helps Xiaoyu’er escape from Yaoyue. She is deceived by Jiang Yulang and loses her virginity to him, and is used as bait to lure Xiaoyu’er into a trap. After she is abandoned by Jiang Yulang, she feels dejected and chooses to join Hu Yaoshi and the Twelve Zodiac. She is ultimately revealed to be Li Dazhui's daughter from.
 * He Lu is a servant of Yihua Palace.
