"The first layer of the Life and Death Unpredictable Needle, 'Life and Death Injection,' refines death qi, possessing the ability to attack opponents. Its actual use isn't very significant; at most it can be used for sneak attacks and ambushes. With slightly better needle and hand techniques, it could compare to a rather powerful poisoned needle method.
Of course, if one only cultivates to this step, speaking frankly, it still doesn't compare to the lethality and range of a handgun, truly not very useful.
The second layer, 'Yin and Yang Split,' and the third layer, 'Heaven, Earth and Man,' after transcending these two levels, the needle techniques become extremely exquisite, able to navigate between reality and illusion, unblocking meridians and invigorating circulation; already capable of posing as those masters of medical needle techniques, able to treat diseases, but unable to fully guarantee whether treatment will be good or bad.
