Transmigrating Into the Turmoil of Republican-Era China

Republican-era China, Spies, No Romance, High Intelligence

I’m looking for Republican-era stories with a spatial ability, but they need to be logical and have intelligent characters. No mindless wish fulfillment. Ideally, no romance. If there is a love story, I hope it’s only a minor part of the plot.

Looking for a Real Anti-Japanese War Story. Transmigrating to the Republic of China and Fighting the Japanese Is No Good. I Want One with Real Battles.
