Bai Ju: Fourteen Years of War

My name is Xu Weiyang. I traveled through time and became the system directly? Did I travel through time and become a resistance system? ? ? Didn't I become the system? Others traveled through books and history, while I became the system directly after traveling through books? I want to experience the entire history of the Anti-Japanese War as a system. The trajectory of history cannot be changed, and the outcome is already determined. Where will this historical torrent take me?
