The field where the Taste Thorns are located, originally belonged to the plant called 'Emperor Xi'.
'Emperor Xi', also known as 'Don't Worry Wood', helps calm the mind and nourishes tranquility.
An old book once said, on Shaoshi Mountain, a countless variety of plants grow. Among them, there is a tree named 'Emperor Xi'. Its leaves resemble those of a poplar tree, its branches intersect and extend in all directions, blossoming yellow flowers and yielding black fruits. One who consumes it can achieve inner peace and tranquility, free from anger.
Due to this effect, modern wizards have categorized it as a 'Neural Soothing' type of plant. The temperament of the shrub and its functioning in pharmacology are quite similar - they are both incredibly mild-mannered and humble.
