In 1937, the city of Jinling was destroyed, and among the mountains of corpses and seas of blood, Communist Party member Su Chengxiao escaped from the Nanjing Massacre with his martial arts skills. In order to avenge his country and his family, he infiltrated the Japanese camp in Xuzhou under the alias "Cheng Xiao" and disguised himself as a cruel, vain and traitorous traitor. He even slaughtered his compatriots with "blood on his hands" just to win the trust of the Japanese army. This "lone wolf" buried deep in the enemy camp was a formidable minion of the Japanese army during the day. At night, he transformed into a black robe and walked like a ghost among the eaves and walls. He used the "Han Xing", a hidden weapon as fast as a meteor, and sharp sword skills to kill senior Japanese generals, making the enemy camp frightened.
After ten years of lurking, he dealt with the admiration of General Yamamoto and the pressing pressure of Special Agent Sato. He was nearly tested countless times but outsmarted the danger and disintegrated the Japanese army's deployment like a cannibal. In the night of Xuzhou City, the black-robed figure is the nightmare of the invaders and the hidden light in the hearts of the underground party and the people. He and the underground party intelligence agent Lin Moqing went from suspicion to acquaintance, and they developed a love in the midst of blood and fire, but they had to hide their love deeply because of their identity. He also went from enemies to side by side with the Kuomintang agent Wang Laohu, demonstrating his chivalrous responsibility under the national righteousness.
When the hidden fuse was ignited by the traitor's betrayal, Su Chengxiao's identity was exposed, shocking both the enemy and ourselves. He sneaked into the underground labyrinth of the ancient city and launched a final life-and-death contest with the Japanese army. With his black robe stained with blood and his chivalrous bones clanking, he used the trust gained from ten years of forbearance as a blade to finally crush the Japanese conspiracy deep in the tunnel. And the story is not over yet - from the war in Xuzhou to the interstellar galaxy, the spirit of the "lone wolf in black robe" spans time and space and becomes the hero of the universe.
