(xiao-ma-yi)
Sound very much like wu xia xiao suo. Your sayings are
completely different from my teacher. He says that qigong will be
able to take blows, but not bullets, or even knives.
qi-gong is actually about internal strength, or "qi". also
called nei-gong.
if your internal strength very high, then can withstand a lot of
physical violence.
however, the modern day skills for training nei-gong, such as
QiGong, very "down-graded" compared to last time Song's dynasty and
earlier.
those skills like JiuYang ShenGong belong to the forgotten
realms/category of nei-gong training already. u never see the real
power of JiuYang before right?
not i want to say, but everytime i see those QiGong masters making
a fool out of themselves by letting trucks roll over them, i really
say "how pathetic it is that they're insulting *real* martial arts
like this"? 
next time, ask your master come see me. he stand 500 metres away
from me and i'll propel him and make him retreat 60 steps against
his own accord, just by channeling out my qi, based on JiuYang
teachings.
With bullet travelling so fast, the impact is going to be very
big. You sure you can take that?
the point is not how fast the bullet is. as long as the qi in
you is always at a very immense and extreme level, no
problem......because the bullet, no matter how fast, will still hit
you at the end.
thus, if your qi inside is boiling strong, bullet, anything, no
problem.
