The Human Fetus Gu could help the Demons plunder what they needed the most.
Moreover, the cultivation of the Human Fetus Gu did not require particularly harsh conditions.
It only needed to be planted in a human, and then Gong Jiu would continuously torture and drive away the person with Human Fetus Gu.
It was enough to search for enough food everywhere.
Other than that, the Demons were basically sitting back and taking advantage of the situation.
Such a situation also existed among humans.
This was because humans had discovered that the parts of some Demons and monsters were extremely nutritious. Many scales, claws, and teeth were also materials used to refine soul artifacts.
Therefore, regardless of whether it was the Demons or monsters, when humans were at their peak, they were almost all livestock that provided food and materials.
