There Are Many Children in the World, and the War Between the North and the South Is Still Going On.

During the Jiading period of the Southern Song Dynasty, the Jin Ge and Iron Horses trampled the mist and rain in the south of the Yangtze River, Shi Miyuan was trapped in the Jin Dynasty, the Mongolian cavalry was spying on the Central Plains, the dirty temples seeped into the rivers and lakes, and the martial arts in the North and South became abandoned pieces on the chessboard. Shen Jinghan, an orphan from Wudang, with scars on his palms and half a token, went from being a book copywriter in Jiangnan Bookstore to carrying a secret letter against gold and rushing into Qiantang; Taihang wild fox Yan Shisan, with two swords wrapped in red ropes, from a horse thief who robbed officials and diverted people's money, to a cottage owner who cut off his fingers to protect grain roads - two teenagers with very different backgrounds collided due to a pursuit by the Black Lotus Cult, and their "personal grudges" became a life-and-death contract to "protect the Central Plains". Su Muyan, the Emei chivalrous girl, guarded the "right path" sign, but broke the rules when the truth about her master's collaboration with the enemy; Liu Qingmei, the black lotus demon girl, quenched the lotus heart poison in her hands, but when her father invested money for power, she sprinkled the poison powder on the Mongolian soldiers. There are also Yan Tu who died in battle despite being unable to save his life, Liu Cangwu who committed suicide and committed suicide, Lin Wanqing who turned to ashes due to obsession, and Zhao Xiaowu who turned from soft bones to a strong backbone... More than two hundred people from the rivers and lakes, some carried swords to guard the passes, some brewed medicine to save the wounded soldiers, some sprinkled their blood on the grain road, and some buried their lives in Zhongdu. From running away from the ruined temple in the rainy night in the south of the Yangtze River, to the oath of alliance at the Huaihe River crossing, to the bloody battle at the top of the Central Capital City, to wielding a sword with one arm in Xiangyang City, they were not born heroes. They just dug their bones into the soil of the Central Plains in the choice of "what to do when the golden dog comes" and "whether the Mongolian soldiers came in to protect the people." In the end, the Huaihe River reunited, and the laughter of the people in the distance drowned out the war drums - it turns out that the best rivers and lakes are never about grudges and grudges, but about people who guarded "the mountains and rivers are safe, and the children are safe" with their lives.
