Xiaofan had already thoroughly analyzed the situation at the munitions factory here.
Of course, since the information source came from Bai Xue, Xiaofan couldn't just reveal Bai Xue's involvement. If Yanhuang Soul needed to confirm the information, they could have Penghai and his team take a look. Once confirmed, they could report back. Why bother sending someone to infiltrate?
What exactly was Liu Xu's motive?
If he sent people to stop Japan's research on mutants, how could such research be halted? If you sent people today, aside from the question of whether you could successfully destroy a munitions factory, what about next time?
This is different from Huaxia's past epidemic with Red Butterfly; once Red Butterfly was eradicated, it was done for. Restarting would be highly unlikely.
