Virus
Sam is currently inside a cave deep inside the forest.
The cave is full of medical equipment that he created. It looked a lot like the modern equipment, but after years of research in the Dusk, these devices are all made to suit the needs of the cultivators.
In the middle of the cave, on the table in front of him laid a Blood Yena, completely unconscious. Sam is currently monitoring its bodily functions with the observation ability.
Blood Yena are kind of unique creatures. They live in large packs. Packs larger than wolves and they have a strict hierarchy. At the same time, they are much more cunning and intelligent that hyenas.
However, there is one thing that makes these creatures more unique than the rest of the canines.
They are outcasts.
Not just canines, the rest of the beasts all despise these creatures because of their uncontrollably gluttonous nature.
They cannot be satiated no matter what.
