Holding the Xiang River Line: Gain a Doppelganger with Every Level

In the bloody battle at the Xiang River, the entire 34th Division was wiped out. I was one of the few survivors. Every time I rise one rank in the military, I gain a doppelganger: a hunter, an enemy regiment commander, a German arms dealer, a Japanese Special Higher Police major, a Northeast Army division commander... My doppelgangers are everywhere, and the enemy will never know that the person standing beside them is me.
