I sensed around me. The density of immortal qi here was not much different from the Immortal Spirit Land in the human world. Besides, humans definitely couldn't enter the spatial-temporal turbulence. Even if they did get in, they would eventually be blown apart and scattered, and no one knew where they would end up.
Although it was easy for demonkind to enter this place, just as Yang Zhenglin had said, they might be blown somewhere unknown. I heard their patrol team had more than five hundred people, equivalent to a police force. Usually, everyone stayed inside the city. When they went out on patrol, experts like Yang Zhenglin occasionally entered the Great Wilderness to hunt, then took the demon essence they obtained to an old man surnamed Bai in the north of the city for processing. The resulting pills were split evenly.
Yang Zhenglin took out a lump of something he said was demon essence and showed it to me. I found that it was like the core energy cluster of a demon. Demon essence seemed to display different colors depending on the demon's attributes. I heard there were also demon essences of special colors, but no one had ever seen them. [corrupted text]
Still, this thing, no bigger than a billiard ball, couldn't be underestimated. It seemed far more advanced than immortal crystals. It was just like how demon beasts treated humans as immortal meat. This thing could be refined into precious pills; the inferior ones were used to restore energy, while the superior ones could help someone advance. That was something I had to keep in mind.
No wonder either demon beasts hunted humans for immortal meat, or humans hunted demons for their essence to refine pills. It was a vicious cycle of contradictions. It was only natural
