Anti-Japanese War: Principal, Buddy, What's Wrong with Getting Promoted Soon?

In the twenty-sixth year of the Republic of China, the Japanese invaded China. Although I came from a humble background, the most outstanding person in my family was my grandfather who worked as a waiter at the Jiang family store in Xikou Town, Fenghua. It's a cool story about the Anti-Japanese War, but it's not mindless and it's not an anti-Japanese drama. The system is only used for logistics, and the weapons and equipment basically meet the background of the times and the needs of the domestic battlefield.
