Chapter of Building China in Troubled Times

This work is the starting point for a hard-core realistic World War II time travel on the military track, the military-industrial system strengthens the army, and the passionate portraits of family and country. It is completely different from the mainstream World War II flow of system cheats, brainless crushing, and cool writing that are prevalent in the market. It focuses on knowledge dimensionality reduction, system completion, infrastructure construction in troubled times, and building national defense foundation with mortal flesh and blood. It does not tamper with official history, does not joke about martyrs, and does not make false stories. It takes the darkest stalemate behind enemy lines in North China in 1940 as the stage to tell the story of a modern national defense engineering expert who traveled through troubled times, trained troops from scratch, built military industry from scratch, deeply cultivated base areas, improved the logistics system, and led the desperate army and civilians step by step from subsistence to self-preservation to strengthening the army to containment to counterattack to building the foundation of the country.
