In the Battle of Cangyunling in 1937, veteran Chen Mo accidentally obtained the "Emergency Support System" and used improved tactics to collect three defeated soldiers during the retreat. With the M1911 pistol and tactical tutorials provided by the system, he destroyed a Japanese transport convoy outside Yangmingpu Airport, attracting the attention of the Eighth Route Army for the first time.
As an unorganized "independent support team", Chen Mo led the team to assist the Shanxi-Sui Army in setting up a temporary field hospital during the Battle of Xinkou, and provided precise blasting support to the Eighth Route Army during the Hundred Regiment Battle. His improved "three-three" tactics and submachine gun team became the mobile sharp knives on the battlefield behind enemy lines. He completed 72 raids and rescued more than 3,000 captured soldiers and civilians.
As the scope of support expanded, Chen Mo discovered that the system equipment drawings were highly consistent with the hand-drawn sketches in his grandfather's diary, gradually uncovering the history of his family's ancestors' participation in "ordnance support behind enemy lines." When Japan surrendered in 1945, he converted the accumulated support points into complete ordnance production line drawings and left them to the Eighth Route Army as a founding gift - this is a supporter legend written by an ordinary person within the historical framework using modern tactical knowledge.
