Because those three nuclear weapons had already been intercepted by drone missiles into outer space, they were now far away from Earth. The nuclear weapons base on Seed Island of Japan had also been completely destroyed by Yan Fei using missiles, and so, there was, astonishingly, no evidence left to prove that Japan had produced nuclear weapons. The intelligence personnel who had previously reported that Japan was producing nuclear weapons had all disappeared without a trace. With no evidence remaining, Japan was miraculously whitewashed.
When Yan Fei discovered this situation, he was somewhat dumbfounded, not expecting that due to his actions, all the evidence unfavorable to Japan had been destroyed, allowing them to miraculously turn the tables in a dire situation, which was simply inconceivable.
