"Four Seas" is a memoir-style novel about rivers and lakes, using the first person "I" - Chu Sihai, a young man from Luancheng, as the narrative perspective. It spans twenty years.
When he was young, Chu Sihai had a weak and cowardly character, but he was obsessed with martial arts novels. He grew up in the streets of Luancheng and bullied the girl next door Shen Mengxue wantonly. He left his youthful evil behind, but over the years he turned into a debt that he could not repay in his lifetime. Later, he plunged into the world of martial arts, and there was no cheating or adventure, only a struggle: the brothers who were side by side in the past were dead, disabled, and scattered. Fate fell one after another - his father died at the age of five; his mother died of overwork and illness at the age of twenty-two in the cold winter; Shen Mengxue, who had been hurt by him, became his wife at the age of twenty-three, but died during childbirth; at the age of twenty-four, in the provincial capital, his brother Chu Jianghe blocked a fatal knife to save him and died on the spot.
Family affection, love, and brotherhood are annihilated one after another, and a half-life of absurdity is replaced by regret. After several life-and-death separations, the Luancheng boy who once thought that the world was a place of grudges and grudges, was finally left alone, wandering alone in the world with a debt he could not repay in his life. This is the story between Chu Sihai and Li Zhenshan, etc.
