Single Player Battle, with System, Without Joining the Team

I want to read a book similar to "The Strongest Single-Soldier Killing System of the War of Resistance". Travel through the Anti-Japanese War era and carry a single soldier to kill the enemy system! Abandon frontal force and defeat the enemy with cunning and sneak attacks. The anti-aircraft cannon blasted the enemy formations with flat fire, and the Vulcan cannon swept across like mowing grass. They killed the enemy with blood and wrote the book of resistance against Japan.

Are There Any Cool Anti-Japanese Novels That Include the Plot of Landing in Japan?

Fight the War Alone, Without Joining Any Organization

Is there anyone who, during the war years, fights the Japanese alone, works alone and does not join any organization?
