During the Second World War, the camp of Japanese "731 Bacterial Corps" should be one of the most horrible and irrational military prisons over the world. For the tens years occupation in Northeast China, the Japanese had conducted lots of bacterial experiments so as to maintain her military strength in the battlefield. Numerous Chinese and Russians as specimen, were killed brutally in the process of creating different kinds of bacterial weapons. In 1945, General Ishii, an Army surgeon aged 53, was appointed by the Japanese military authorities to be the commander of 731 bacterial detachment, aiming to accelerate the production of pest bacillus. There was a ‘junior team’ in the 731 corps, which was formed by Japanese youths aging from 13 to 15 and was under the leadership of Kawasaki, a 45-year-old soldier. To speed up the production of bacterial weapons, Ishii ordered his subordinates to accelerate experiments. Youths of junior team were trained by Kawasaki various techniques including killing, ill treatment …etc. Countless specimen were put to death by means of dismemberment, blood-letting, injection with pest-bacillus, lowering the pressure, freezing, explosion and poison gas … The specimen rebelled against Japanese under such merciless experiments, but unfortunately, most were shot down in the 731 camp. Only one of the Chinese specimen ‘Little Stone’ was saved by the member of junior team, Ishikawa, and was kept inside the crematoria. After the atomic bomb had broken Hiroshima and Nagasaki to pieces, Ishii understood the defeat of Japanese and ordered to destroy all facilities, witnesses, records and information of the 731 corps before his return to Japan. Helped by Ishikawa, ‘Little Stone’, the last Chinese survivor, disguised as Japanese and ran away together with the 731 corps. But he was discovered and killed by Okami at last.
