It tells the story of an orphan girl Lin Yanzhi who fled to the end of the world with half a rusty sword. A tragedy that killed her family pushed her from an ignorant girl into a turbulent world. The broken sword in her arms was not only the last thought left by her mother, but also contained a secret that could stir up the world of martial arts - related to the peerless martial arts that had been lost for hundreds of years, and also involved the shocking conspiracy of good and evil twenty years ago.
On the way to escape, she encounters Shi Gandang, a simple and honest mountain village boy, and the two go together by accident. One is burdened with a blood feud and has just mastered swordsmanship but is struggling in his heart; the other is blessed with innate divine power and enters the arena ignorantly but sticks to his true heart. They passed through the disputes of aristocratic families in the misty Jiangnan, broke through the demonic sect stronghold in the western desert, climbed the precipitous mountain peaks covered with snow all year round, witnessed the deceitfulness of the human heart amidst the light and shadow of swords, and gradually formed a bond in the desperate situation of support.
The pursuers follow him everywhere, including gangsters who covet the secret treasure, as well as high-ranking sects under the guise of hypocrisy. Lin Yanzhi gradually discovered that the tragedy that year was far from an accident, and even the people she trusted might have hidden agendas. When the other half of Broken Sword reappears, and when the grievances between her father's generation surface, she has to make a choice between revenge and morality, and tempers and grows up in the entanglement of love and hate.
This is a journey about salvation and perseverance: some people will do whatever it takes to gain power, and some people will sacrifice their lives for love; although the sword is broken, it can spell out the outline of the truth; although the human heart is dangerous, there is always a glimmer of light that illuminates the way forward in desperate situations. A million words long, it will unfold a long martial arts scroll that includes the rise and fall of sects, the deep love between master and apprentice, and the righteousness of family and country. It will describe the passion and tenderness of the children of the world in the light of swords and shadows.
