In this leg's Roadblock, one team member had to retrieve seven coins representing the seven emperors of the Nguyễn dynasty at Minh Mạng Tomb then bring them back to Khải Định Tomb, where they would find out that they had to place the coins in the correct order of the reign of the emperors to receive their next clue.
