The location is lined with massive pipes, which Yusei and Sect used as the track for their Turbo Duel. After Sect lost the Duel, he performed a ritual, which caused the Skeleton Knight to appear on an altar which had not been there before. Yusei then faced the Skeleton Knight in another Turbo Duel in the factory. He won by smashing a pipe, forcing the Skeleton Knight's D-Horse to stop in its tracks, causing the knight to lose the Duel.
