Kau Mor Tze had a burning ambition to learn the best martial arts that the world had to offer. The two martial arts that he coveted most and could not get were Shaolin's Yik Gun Ging and Dali's 6 Mak Divine Swords. Kau Mor Tze would go to any lengths to obtain either of these martial arts; to have them both was probably his most fervid dream.
Imagine this: you are Kau Mor Tze. The Janitor Monk appears before you with the Yik Gun Ging in one hand and the 6 Mak Divine Swords in the other. He is offering ONE of the two manuals to you. He will allow you to take one of the two manuals for your possession (both manuals are written in a language that you can read, so either one will be useful to you), but if you try to take both from him, he'll kill you on the spot (and this is the Janitor Monk, so he can definitely make good on that threat). Which one will you pick? The Yik Gun Ging, or the 6 Mak Divine Swords?
Which one do you think Kau Mor Tze would have actually picked if he were given this choice in such a scenario?
