Courtyard House: Reborn in the 1940s, Starting with Killing Japanese Devils

Traveling back to 1942, after the fall of Beiping, Zhao Heng infiltrated the city as "Lone Shadow," a high-ranking member of the Beiping underground Communist Party.
He also unexpectedly awakened a system, and successively acquired a massive amount of firearms, ammunition, supplies, money, and real estate.
With the abundant supplies provided by the system, he infiltrated Beiping Station, secretly killing Japanese invaders while directing the underground party to carry out various sabotage operations, achieving numerous feats.
After the founding of the People's Republic of China, Zhao Heng joined the Logistics Department and, based on his outstanding past achievements, rose all the way to the position of vice minister.
