I'm Dead Serious About Fighting the Japanese

I am Haotian, a futuristic liquid-metal nanorobot with a humanlike emotional core. I need to eat to replenish the energy that keeps me running. When a mutation of a virus left over from the last century ravaged the future of Huaxia, I traveled to the Northeast in a one-way time machine. My mission is to disrupt the Japanese army’s germ warfare research while strictly avoiding excessive interference with history.
