The most important factor on the battlefield is always people. Gao Yang understands this very well, so he wasn't surprised at all that the Black Demon could find a way to counter drone surveillance.
The only thing Gao Yang couldn't figure out was how formidable the Black Demon unit was over twenty years ago when they were still young.
People have no choice but to accept aging. As people get older, the decline in physical functions is inevitable. If maintained well, the decline is slight; if not, it's more severe. But the fact that the Black Demon remains so formidable even as they age raises the question—what were they like when they were young?
The tactics of the Black Demon can only be used once, because once you know what they'll do, Gao Yang will naturally adopt targeted tactics. However, if it were a real battle, one total annihilation would be enough.
