In the late Southern Song Dynasty, Xiangyang City was in danger. The Five Wonders of the World have long become legends in the world, and the Condor Heroes have disappeared from the world. Murong Chengying, a lonely swordsman with the past of a declining family, stepped into this lonely city destined to be devoured by war for a long-forgotten promise. He originally wanted to be a passerby, but due to Guo Jing's righteousness for his family and country, Huang Rong's clever schemes, and the unrelenting fight between the soldiers and civilians in the city, he was gradually drawn into the center of the current of the times. The sword in his hand has seen the brightest brilliance of humanity, and has also killed the darkest demons and monsters. In this lonely city that attracts the attention of the world, he is neither a savior nor a great hero. He is just a lone traveler who does not want to let the sword in his hand sleep under the afterglow of doomsday.
