The name of the world is often based on natural rules and the dominant biological groups.
Before the chaos apocalypse, Spirit People scientists who were enthusiastic about archaeological research discovered through a large number of geological fossils that in the spirit world during the ancient period, there was once an extremely powerful creature, which even once governed this world for a long time, far longer than the history of Spirit People.
They were called dinosaurs by the Spirit People.
However, such a powerful biological group mysteriously and suddenly faced extinction overnight, allowing the later Spirit People to dominate this world.
According to scientists' research, the ferocity and cruelty of the creatures in that time far exceeded what later generations imagined. What really caused these creatures to go extinct?
Thus, scientists began to make extensive guesses based on the worldview extended from spiritual science.
