Beacon Fire Reverse Journey 1931

When I opened my eyes, there was a Czech light machine gun in front of me. The squad leader's roar came to my ears: "Wu Shuang! What the hell are you doing! The Japs are coming!" I looked down at my rough hands. The military uniform was covered in smoke and blood. I was still playing games in the university dormitory last night, and now I am in Peking University Camp on September 18, 1931. What's even more ridiculous is that I actually know what will happen next - this battle is just the beginning.
