When Jen Yu sits down at the table in the bar (the scene where the big brawl takes place), she is then surrounded by several men. She speaks to a guy named Gou and tells him he'll be the first to feel her sword today. Then you see Gou crash through the outside guar-drail on the top floor of the bar. A section of the guard-rail has now been shattered. But when the big fight in the bar ends, you see the same outside-view of the bar, only the section of guard-rail is back! Magic!
