Lord Buddha Was on a Business Trip, and My Adjutant and I Were Stunned on the Spot.

The story revolves around an antique bronze mirror in Changsha City that can "reverse yin and yang". Lord Buddha went on a far journey, leaving Eighth Master Qi Tiezui and Lieutenant Zhang Zhang Rishan to look after the house. While taking stock of Fo Ye's newly acquired antiques, Ba Ye and his adjutant accidentally touched a strange "inverted yin and yang mirror" at the same time, causing the two people's personalities and behavior patterns to completely interchange: Ba Ye, who was usually well-spoken, became taciturn and extraordinary; while Adjutant Zhang, who had always been steady and capable, turned into a timid and talkative person who was fond of fortune telling.
