Zi Ji is the guild master of the Black Moon Merchant Guild. He normally resides in the guild headquarters building in Divine Phoenix City.
He is married to the leader of Supreme Ocean Palace, Qu Fengyi. Their parents arranged the marriage so that the merchant guild and the Sacred Ground can be united as one entity.
Zi Ji always treated Yun Che very courteously and respectfully. It was his business style to show preferential treatment to those with high strength or innate talent.
His appearance is that of a medium stature old man dressed entirely in purple.
