Anti-Japanese War: Starting from Qingfeng Village

Unexpectedly, due to an accident, I traveled back to the Anti-Japanese War period, and actually became a major battalion commander of the National Army. What's even more surprising is that I actually have a biological brother, that is, Zhu Ziming, the head of Qingfeng Village in "Snow Leopard". My name is Zhu Zizhang, and I am a retired military officer from later generations. The regret of having to change careers due to a back injury has always lingered in my heart. So when I knew the timeline I was in, the long-extinct passion in my heart burned again, thus activating my own golden finger and starting my own legendary journey.
