Plant Spirit Lifeforms were an extraordinarily rare kind of being. They were true living creatures, yet they could form contracts with cultivators and be wielded almost like weapons.
Unlike ordinary spiritual artifacts, they had a degree of self-awareness, which allowed them to react on their own when their master was in danger.
They were also remarkably hard to kill. A powerful Plant Spirit Lifeform could restrain enemies, shield its master, and keep fighting even after taking injuries that would destroy an ordinary creature.
Naturally, something that valuable was very difficult to obtain. Most Plant Spirit Lifeforms instinctively rejected cultivators who carried too much killing intent or an impure aura.
Only people with certain special physiques and naturally harmonious spiritual auras could approach them without provoking hostility right away. For that reason, cultivators who were able to tame a Plant Spirit Lifeform were rarely thought of as vicious or treacherous people.
