Trapped in Stalingrad, I Built an Army from Scrap Metal

Lin Ran, a modern military engineer, accidentally fell into Stalingrad in 1942. At the beginning, the city was blocked by artillery fire and supplies were cut off. What's even more outrageous is that he is bound to the battlefield recycling system. Scrap metal can be dismantled into parts, the wreckage can be made into weapons, and missions can also unlock blueprints and resources. While others guard the street, he wants to turn the entire ruins into an arsenal, taking wounded soldiers, workers and young soldiers to fight his way through the ice and snow.
