What?! I've Transmigrated Into a Purebred Japanese Soldier! The Sky Is Falling!

Parallel universe. Please do not compare this to history. At ninety-two, Ling had died peacefully of old age. She thought she would drink Meng Po's soup, cross the Naihe Bridge, and be reincarnated properly. But before she could even open her eyes, someone beside her roared, “Bakayarou!” She wondered: Could you run into Japanese devils even while getting reincarnated? Was this the same Underworld system? “Why are you crying? Whose young miss died...?” Oh... she was that young miss. Waaah... It had taken her all this time to become a young miss, only to end up as a Japanese girl. Just as she was getting ready to die first and ask questions later, she was forcibly bound to the System. Fine! She'd die later. Better to live badly than die well. She'd pull off a few jobs first. Just as she was thinking something was missing, she discovered that the necklace she'd brought with her was a pocket dimension. After a moment's silence, the old woman broke into a slow smile. How could she die now? Then... she might as well go all out. Relying on her pocket dimension and her old-lady cunning, she quietly got things done behind enemy lines. She emptied one arms depot after another and severed one supply route after another... Just as the enemy began searching the whole city for spies, Ling had finished off this batch and was preparing to move on to the next place when she unexpectedly rescued a fellow countryman who was being hunted. In the glow of the flames, she saw his face. The face she could never forget, and dared not forget. Her young father was covered in blood and grime, his eyes wary and weary. Yet the instant his gaze met hers, he froze for a moment. He didn't know why the young miss from an enemy nation had saved him, much less what the overwhelming emotion in her eyes meant. Ling didn't explain. She stuffed all the vital intelligence and supplies into her father's arms. Then she casually said something he couldn't understand and turned away, her eyes reddening. Dad, don't be afraid. This time, I'll protect you.
