Three Hours Until I’m Done For: Killing Japanese Soldiers Makes Me Stronger

[War of Resistance] + [Transmigration] + [Parallel World] + [Guilt-Free Power Fantasy]... Kill one Japanese soldier and gain one extra day of life. If you don't bring out nuclear weapons, I won't bring out the male lead... “Captain Sakata, you must stay far away from a place called Cangyun Ridge. Otherwise, you'll surely meet your end there!” “Hahaha! Captain Sakata, you're on your own!” A Japanese soldier with a katana sticking out of his stomach laughed as he spoke. “I'll prove my resolve with my death. Please, Captain Sakata, you have to believe what I'm saying. Otherwise... the Empire is finished!” A master of the Kiku Sect, a Japanese man from a later era, said unwillingly. I'm no good at writing a synopsis, so please head straight to the story. (This is absolutely not AI. The author is a real person.)
