That was why the creatures of the forbidden land did not attack the heavenly human tribe, the quasi-immortal tribe, or the heaven destroying Army. They were afraid of the powerful cultivators at the origin realm.
In the past, the heavenly human tribe had defeated the evil demons because the origin of the evil demons had been sealed in the dark Universe.
