In the Divine Tree Continent Breakthrough Secret Realm, Lu Ran saw the effects of the ferocious plants and was inspired to have Dark Crow study the power of ferocious plants, specifically researching plant curses.
In fact, Dark Crow had indeed been researching, but as for effectiveness, well, after all this time, only one had been successful.
The red dandelion, a ferocious plant, has parasitic effects when its seeds land on a living being, causing their entire body to grow red hair, which then severely disrupts energy flow within the body, making it difficult for the living being to release skills.
At first glance, it might not seem like a particularly powerful effect, but the red dandelion is notorious in the realm of ferocious plants because, although it doesn't pose a strong threat by itself, it is an excellent accomplice to other ferocious plants, often allowing them to overpower their prey with little resistance.
