Sh aofei asks about his injury, and the witch doctor tells him that it normally takes a lifetime for someone to awaken his silver needles, but that he can do so in one go. The reward is the same as the medicinal king vessel , which is a yin-yang plate with five-elements . The water element can heal the heart, the fire element can cure the lungs, and so on. He says that he'll study the water element when he's free, and he thanks the doctor and the yellow man for treating him. He'll thank them later, when he can thank them. The witch doctor explains that the ghost clan is a branch of the tcm system that has mastered many magical skills. The most famous of these skills is the "13 needles of ghost-clan" . It's said that even if a patient has stepped into a death, the ghost-cloak can save him or her. The ghost clan has gone out of existence for a hundred years, but there's still a legend that they preserved their medical methods in an underground palace. The snow season is here, and Sh Aofei decides to go find the underground palace and get its medical methods.
