I Transmigrated to the War of Resistance and Served My Country

I transmigrated to the period of the War of Resistance Against Japan. Unit 731 had committed countless atrocities, and I joined forces with the Eighth Route Army to fight the Japanese invaders. The viruses and the cruel methods would all be driven out of China. "You, go in and be tested." I was shoved into the freezing chamber. They wanted to use those methods to make medicine for frostbite. The human body is 75% water, and the world's best frostbite medicine all came from them.
