Five Point Palm Exploding Heart Technique
The Five Point Palm Exploding Heart Technique was a legendary technique developed by Pai Mei. By striking a series of pressure points on the victim's chest using three quick hits with the palm, the user of the technique inflicts the deadliest of blows. The target is fine, until they take five steps, after which their heart explodes. Bill and (presumably) Elle Driver were never taught the technique by Pai Mei, but the master did teach it to Beatrix Kiddo.
