In the inn, he met "Double Barrel" General Ding Yanping. Luo Cheng recognized Ding Yanping as his foster father. Luo Cheng learned from Ding Yanping the trick of breaking two guns with a single shot: double-barrel shoot, single-barrel pierce, double-barrel hold, single-barrel pull. The first word determines the marksmanship; then spin around and pin the elbows. Luo Cheng went to Wagang Mountain to offer respect to his brothers, drink and toast.
