Butterfly Incense was a superior class herb extracted from the Butterfly Flower.
It was extremely expensive. One gram of the incense was worth 100,000 silver coins.
Many of the female warriors who practiced Martial Arts liked Butterfly Incense not only for its long-lasting smell but also its calming power.
The odor would last an entire month each time they applied it. Bathing would do nothing to wash away the fragrance.
After applying Butterfly Incense, a warriors' breaths would be completely concealed. Other warriors would not be able to detect them. Like Zhang Ruochen now. He could only smell the odor of Butterfly Incense on the scarf rather than the actual breath of the female heresy.
Aside from Duanmu Xingling, there were countless female warriors who liked Butterfly Incense. It would be impetuous for Zhang Ruochen to assume the female heresy was Duanmu Xingling.
BOOM!
The ground shook and the horses groaned.
