Transmigrating Back to Fight the Japanese Invaders

I unexpectedly transmigrated back to the War of Resistance against Japan and ended up as a collaborator, working for the Japanese alongside my grandpa.

The System crashed, so I had to rely on myself for now.

First a collaborator, then a bandit, and finally I joined the regular army.

Wherever I go, I fight. There's only one rule: kill the Japanese without mercy, and never take prisoners or leave anyone alive.

Whatever else happens, fighting the Japanese is the reason we started, and we must never forget it!
