During the 1937 Battle of Cangyun Ridge, veteran Chen Mo unexpectedly acquired the Emergency Support System. While retreating, he used improved tactics to rally three scattered soldiers. Armed with an M1911 pistol and tactical training supplied by the System, he destroyed a Japanese army transport convoy on the outskirts of Yangmingbao Airport, drawing the attention of the Eighth Route Army for the first time.
With no official military assignment, Chen Mo led his “Independent Support Squad” in helping the Jin-Sui Army set up a temporary field hospital during the Battle of Xinkou and providing the Eighth Route Army with precision demolition support during the Hundred Regiments Offensive. His improved three-three system tactics and submachine-gun teams became a nimble spearhead behind enemy lines. They carried out seventy-two raids and rescued more than three thousand captured soldiers and civilians.
As their support operations expanded, Chen Mo discovered that the equipment blueprints provided by the System closely matched the hand-drawn sketches in his grandfather's diary. He gradually uncovered the history of his ancestors' involvement in “behind-the-lines ordnance support.” When Japan surrendered in 1945, he converted the support points he had accumulated into blueprints for a complete arms-production line and left them to the Eighth Route Army as a gift for the founding of its army. This is the legend of an ordinary man who used modern tactical knowledge to become a supporter within the bounds of history.
