Natasha immediately inspected the parts inside the dolls, hoping to find serial numbers or similar clues that could be traced.
These doll robots ran on batteries and could attack the nearest person like landmines. After attacking, they would even perform a short musical piece.
That was their programming.
These doll robots were disposable, so they should have been mass-produced. Mass production meant large quantities of identical components, such as capacitors or diodes, which should all bear manufacturer serial numbers.
That was what she wanted to find.
Although this was not her first time coming to Japan on a mission, she did not know that Japan's national conditions were completely different from elsewhere.
During World War II, the industrial model represented by the major powers of Europe and America was centralized and intensive, such as Germany's Ruur industrial region, Liverpool in the United Kingdom, and Pittsburgh in the United States.
Large factories were densely packed in those places, the workers were highly specialized, assembly lines were efficient, production capacity was high, and standards were uniform. Their only weakness was their fear of bombing.
In the later stages of World War II, Germany's Ruur region had been bombed to pieces by the Allies, causing the German Army's industrial output to plummet by forty percent.
Japan, meanwhile, had its large military products manufactured by a small number of factories, such as warships.
But all sorts of smaller components, such as lights used on aircraft carriers and tank treads, were subcontracted out to countless family workshops.
In Japan, this was called "Distributed Contracting," a division-of-labor system with distinctive Japanese family-culture characteristics.
A decentralized industrial system was more resistant to air raids and other sabotage, but its drawback was that quality control was difficult to guarantee. Even identical parts produced by different workshops would have
