War of Resistance: Unit 731, the Doctor in the Enemy's Shadow

Lin Mo, a top surgeon of the 21st century, had his soul transmigrate by accident to the Northeast in 1939, where he became an educated youth captured by the Japanese army. Thanks to his rare medical background, he wasn’t treated like an ordinary laborer. Instead, he was sent to a top-secret facility that didn’t exist on any map: the Kwantung Army’s Epidemic Prevention and Water Supply Department headquarters, code-named Unit 731.
