The Blood Vitality Grass required stringent conditions to grow. First of all, its seeds were too rare and looked no different from the pollen of regular grass.
For the seed to mature, it had to be swallowed by a Martial Origin Stage Origin Beast that lived in a place abundant with Origin Essence in the air. This, coupled with the Origin Beast constantly devouring other origin beasts was a needed condition.
And slowly, the Blood Vitality Grass absorbed the blood from the Origin Beast's body, growing in size. Its growth required a lot of nutrients, blood, and Origin Essence, causing the Origin Beast to constantly be on a hunt for prey.
But, it wasn't all cons for the Origin Beast as the Blood Vitality Grass would slowly begin to share its essence with the Origin Beast, strengthening it gradually over time.
It was a symbiotic relationship.
