Chen Xiao, a modern retired military doctor, accidentally traveled to the third year of Jianyan in the Southern Song Dynasty (1129) at the Yuewang Temple in Hangzhou, when the Jin soldiers invaded the south and the mountains and rivers were shattered. When he was about to die, he was rescued by Yue Fei. Because he was literate, understood medicine, and knew tactics, he was accepted as a soldier and given the name "Yue Ling". He personally experienced the iron law of Yue Fei's army "do not demolish the house to death", participated in the battles such as the recovery of Jiankang and the pacification of Yang Yao, and used simple firearms and field medical treatment to help Yue Fei defeat the weak. He became sworn friends with Yue Yun and guarded the glimmer of troubled times with the medical girl Shen Qingwu. He even urged Yue Fei to disobey the order of the Northern Expedition, but finally understood his belief that "loyalty is not foolishness, but the ambition to maintain peace in the world." After the victory in Yancheng, Yue Fei was recalled with twelve gold medals, and ten years of achievements were ruined. In front of the Fengbo Pavilion, Yue Fei entrusted "Wu Mu's Suicide Note" and simply said: "Look at the snow in Bianjing for me." After Yue Fei's death, Chen Xiao did not raise his troops to take revenge, but remained anonymous, passing on his legacy to Yue Lin and cultivating the anti-gold fire. Many years later, after the great victory in Caishiji, the young man shouted "This is Grandpa Yue's ambition!" And the white-haired Chen Xiao silently recited "Man Jiang Hong" - he failed to save Yue Fei, but he made "Yue Fei" live in the hearts of millions of people.
