This story is entirely fictional. Set after the Wannan Incident during the War of Resistance Against Japan, it vividly portrays the transformation and operations of the Central Anhui Base Area, the Wanjiang region, Jiangnan, and other resistance forces, with the New Fourth Army's Seventh Division as its backdrop. Once focused purely on military operations, they evolved into an economic logistics and military intelligence hub for the New Fourth Army.
The story focuses on how, in the Wanjiang basin, then the richest and most prosperous region in China, the Chinese Communist Party led the New Fourth Army and other soldiers and civilians in the resistance to achieve major successes on both the economic and intelligence fronts. It also recounts how trade and financial warfare weakened and depleted vast numbers of the enemy's forces.
