Many powerful figures like to adopt titles, such as Jiang Busi who is known as the "Undying Daoist," or the previous owner of Jiang Lang's Silent Virtue-Stealing Flute who called himself the "White Jade Prince."

Titles can be chosen freely, but those with the character "Immortal" are not taken lightly, or else they would be ridiculed.

This is because only those at the Earth Immortal level typically adopt such titles.

The Chrysanthemum Sword Immortal was an Earth Immortal expert, who loved cultivating chrysanthemums and was a master swordsman, hence the name.
