It had been dozens of years since Shangguan Fei started practicing kung fu at the age of five, but he had never understood the profundity of it.
To him, kung fu was filled with danger, and no matter how skilled one was in it, one could still be killed by someone weaker or even untrained in kung fu due to a moment's carelessness.
He wished that there was a type of kung fu in this world that would allow its practitioner to stop practicing upon mastery. Whether being attacked directly or facing a sneak attack, it would help its practitioner to react immediately, even when he or she was asleep.
It was a pity that there was no such type of kung fu that could accomplish that; the more powerful the kung fu, the more it needed its practitioner to be on all alert.
