Therefore, without reasoning by the technology extrapolation system, there's no manufacturing process, and without a manufacturing process, products cannot be produced, which creates a vicious cycle. Moreover, it's impossible to find the manufacturing process for nuclear weapons on the internet, but even if it were available online, Yan Fei believed the Auxiliary Brain would not record such a manufacturing process. In other words, the mini-production workshop in the Drone simply couldn't produce weapon-grade nuclear weapons.
When Yan Fei realized this truth, he went from elation to deep sorrow in an instant. For some unknown reason, the Auxiliary Brain actually rejected the deduction of the nuclear weapons manufacturing process proposed by Yan Fei, which meant it refused to produce nuclear weapons for him. This situation had never occurred before.
