The blue taiji diagram in Dream Zhu Xian 2 is printed.

This kind of French seal is called yin-yang fish. At 4pm on Saturday, there is a FB entrance on the map of Zhu Xian Sword Soul. Team members will enter and fight monsters. There is a chance to drop the pages that make up the array of Yin and Yang fish. Collect six different pages of text and exchange them with NPC. If you don't want to fight, you can go to Heyang, where there are stalls to sell.
