Li Yi, from the Logistics Support Department of the modern military industry, accidentally traveled to the anti-Japanese base area in 1940 and became the acting director of the Logistics Department. Faced with the desperate situation of running out of food, zero ammunition, and no medicine for the wounded, he relied on his logistics management knowledge that transcended the times and a complete "people's demand system" to create a steel logistics system that supported the entire strategic area. This is not a heroic legend of one person, but how a nation rose from the ruins.
