The sword of an ancient Taoist never left his body. Besides exorcising evil spirits and killing evil spirits, are there any other functions?

Sword is an instrument that can ward off evil spirits and slay evil spirits, and it is also a symbol that can slay evil spirits. There is also Taoism, which focuses on double cultivation of life and attaches importance to physical exercise. It also attaches importance to inner spiritual cultivation, and sword, as one of the main instruments of traditional martial arts, coincides with the ethereal freedom pursued by Taoism and is naturally loved by Taoists.
