He is the youngest company commander of the Eighth Route Army, brave, good at fighting, clever and cunning; he never plays by the rules, resourceful and unique, which makes the enemy terrified; he is the hero in the heart of the passionate and aggressive female captain Liu Hongmei, but he only loves the beautiful and intelligent instructor Liu Yanfei; his parents died early, and he was proud of his father who was a warrior like Guan Yu. His name is Fu Xiangming. He is an old soldier of the Kuomintang, a slippery and cunning brother in the army; he has his own wonderful survival rules in the war, and he is like a fish in water in the army; he is full of lies and bad habits, but he is also a sharpshooter with rich practical experience; he lost his wife and son in his early years, and his biggest wish now is to stay away from the war, marry and have children as soon as possible, so he chose to be a deserter; his name is Tian Shouyi. The Japanese Major Kato's troops are a poisonous tooth planted in the Jin-Cha-Ji area. Kato is a vicious and cruel person. He excludes his colleagues and seeks credit. He also wins over the puppet army Chen Keli's troops to become his cannon fodder in the war, launches brutal attacks on the Eighth Route Army, and implements the Three Alls Policy in the non-ruled areas. Fu Xiangming is ordered to fight against Kato's troops. A fierce battle brings Fu Xiangming and Tian Shouyi together unexpectedly. The deserter Tian Shouyi rescues Fu Xiangming who is surrounded by the Japanese army and follows him back to the base. Tian Shouyi fell in love with the beautiful widow Xiaofeng at first sight, and pursued her shamelessly, which disgusted everyone. Only Fu Xiangming had an idea to keep Tian Shouyi and let him train new soldiers for the base. The two smart men, old and young, fought wits and courage with their own purposes. Tian Shouyi sneaked away several times, and Fu Xiangming played hard to get and subdued him. However, at this time, they didn't know that they were actually the father and son who had been separated for many years... Kato began to kill more brutally. Fu Xiangming and Tian Shouyi joined forces to cooperate with the enemy again and again: assassinating the Japanese leader, thoroughly investigating the Wanggouzhuang blood case, instigating the rebellion of the puppet army, cleverly seizing military supplies, wisely and courageously solving the traitor case, seeing through the serial spy plan, etc.... The mystery of the father and son's life experience was finally revealed in the battle. In terms of war, feelings, and life, the father and son have different positions and different concepts, which have caused thousands of contradictions. They just recognized each other, and then fought each other, and the father and son had constant disputes. Dangers came again and again, and Tian Shouyi finally woke up in the fierce battle. He strengthened his revolutionary beliefs and fought side by side with his son. Kato's troops planned a new combat plan, and a fierce battle was imminent, and father and son joined the battle. Fu Xiangming has always been the pride of his father. This time, Tian Shouyi finally became a warrior that his son truly admired... On the bloody battlefield, flesh and blood fought to end their grudges; swords flashed, and life and death fought to the sky!
