Song Ciwan hadn't used only Five Elements Magic to kill the Demon Insects.
Of the Five Elements Magic she currently knew, the Blazing Flame Technique was one, belonging to the Fire Attribute.
Call Wind and Rain was likely Water Attribute, but the technique was too ostentatious and lacked any subtlety, making it unsuitable for use during a tracking mission.
Song Ciwan hadn't used this Daoist Skill in a long time. Even though it was a Celestial Spirit Daoist Skill, she couldn't be bothered with it unless absolutely necessary.
Using it carried the risk of revealing an old affair—that she was the one who had killed "the Second Young Master."
If trouble could be avoided, Song Ciwan was more than willing to avoid it.
The Blazing Flame Technique was common; too many people knew it. It wasn't a signature move, so she could use it without any worries.
