When Chiu Mun threatened to use the Heaven Sword to mutilate Chow Chi Yerk's face at Man-On Pagoda, Cheung Mo Gei saved Chow Chi Yerk by throwing the golden box that Chiu Mun had given him as a gift earlier. This is the golden box that contained the Black Jade Ointment that healed Mo Dong Heroes Yu Doi Nam and Yan Lei Ting's crippling injuries.
Chiu Mun cut the golden box cleanly in half using the Heaven Sword. By all rights, the Black Jade Ointment contained in the box's secret compartment should have all oozed out. Later, however, when Cheung Mo Gei attempted to heal the critically wounded Sung Ching Sheu at Shaolin Temple, there was still Black Jade Ointment in the golden box. How is it that there was still ointment in the box after it had been cut open?
