Anti-Japanese War: at the Beginning of the Space-Time Gate, the Whole Country Fights Against Ghosts

After returning home from the army, Lin Chaoyang found a strange metal door in the basement of his ancestral home. Stepping into it, you are actually the hometown that was full of wind and snow in 1936! The atrocities committed by the Japanese aggressors, the bloodshed of his compatriots, and the hell on earth in front of him made him dizzy! He knew that this door must not become private property. Without any hesitation, he dialed the dusty number. "Zhao Lian, I found a huge opportunity, related to the country's highest security!" One phone call, detonating the highest level! When a newspaper from 1936 suddenly appeared with a date written in a modern pen, the entire command center was shocked! A top-secret project codenamed "Long Yin" was launched.
