Fatty asks if wang can really cure his grandson, but wang says that he can't promise anything. Fatty wants to know what the "mad needle formation" is, and wang explains that it's a special type of needle that's used in acupuncture to increase a person's "potential" before a battle. Fatty gives wang a picture of the front, back, and side points of his body, which wang uses to draw the formation. Fatty asks wang to take the picture and give it to him. Worried about Fatty's health, wang tells Fatty to go back to his house and get some more live tubercular fleece.
