In a world where humans and monsters coexist, some people do not accept that they have built a wasteland city on the edge of the dead zone where monsters can be exchanged for flowers. They claim to destroy all monsters.
If a person wants to cultivate immortality, he needs spiritual essence. People are born with it, but they need to have qualifications before they can cultivate immortality.
The demon is Yuan Jing
The monsters transformed from the Dead Realm are called coreless creatures, and they will devour spiritual marrow and Yuanjing.
In the later period, Cuihetang in the wasteland city fused humans and non-nuclear creatures and turned them into giant spirit cores (there are three in total)
Intention: Don't just think that the old ideas are the best
