Are those babies real in the second part of Black Sun 731?

The baby in Black Sun 731 is fake, but the incident is true. There are two parts, the first part and the second part, and the second part is clearer. Don't forget the national humiliation.

Unit p>731, the full name of which is the 731st epidemic prevention and water supply unit of the Japanese Kwantung Army in Manchuria, is called Ishii Unit or Jiamao Unit. It is the Japanese invaders who, under the guise of studying the prevention and treatment of diseases and the purification of drinking water, actually use living China people, Koreans and allied prisoners of war to carry out experiments on the effects of biological weapons and chemical weapons.
