There were various types of Magical Beasts in this world, and plant types are naturally not an exception.
Unlike heaven and earth materials that are born naturally but they can't gain sentience and intelligence. Plant-type Magical Beasts were initially only ordinary plants that inhaled spiritual energy and gradually transformed into Magical Beasts.
Usually, the cultivation of plant-type Magical Beasts are ridiculously slow. For example, this Willow Tree; it had been cultivated for a hundred years but could only advance to a Rank 1 Magical Beast.
However, compared to other Magical Beasts, plant types usually had the most extended lifespan. A hundred years for mortals may not even be their lifespan. Therefore, their slow cultivation is quite reasonable.
Qin Yi continued to observe the Willow Tree then asked casually, "Does it attack people?"
