A Necrotic Mother Leaf tree was named as such because it had the ability to corrupt everything and anything around it, from living things down to even the spiritual qi within its vicinity. Its entire body was corruption, bar the fruits and flowers that, funnily enough, had quite beneficial properties. For example, the fruit was one of the best for healing soul-related injuries while also strengthening the soul. The flowers could cure various poison-related maladies, especially yin-based ones, and they also increased someone's sensitivity toward sensing the principles of the Grand Dao floating around.
Of course, few could live long enough to actually harvest them, as the Necrotic Mother Leaf tree, especially a mature one, could kill even a peak Domain expert and even severely injure those in the Soul Formation realm.
