Intense pain forced me to open my eyes. After getting familiar with my surroundings, I realized I'd been transported to the body of a middle-aged German man. Damn, my mind wasn't listening, and I couldn't remember my own name. Apparently, I'd lost my memory. Fortunately, I knew I was Chinese. How did I know I was Chinese? Because my brain automatically converts the German I hear and see into Chinese. It also automatically converts the language I want to speak into German. The yellowed calendar marked the year: October 4, 1938. It seemed I had a new identity: Erich von Richthofen.

But clutching his Zippo (his only token of the future), he was determined to overturn the script and personally rebuild British glory at 10 Downing Street.
