He calls Elle Driver, another former Deadly Viper, and arranges to sell her the Bride's unique sword for a million dollars. He seals the Bride inside a coffin and buries her alive.Years earlier, Bill tells the young Bride of the legendary martial arts master Pai Mei and his Five Point Palm Exploding Heart Technique, a death blow that Mei refuses to teach his students; the technique will supposedly kill any opponent after he or she takes five steps.
