Following the Foundation Establishment demon beast disappearing, it did not take long for one of the Nascent Soul Realm demon beasts to notice the fact that it had disappeared without a trace. Making it realize that there might be another path out of the underground space, that did not involve fighting with the swarm of spiders that was blocking the path it and the rest of the demon beasts had used to enter the underground space.
Swish-!
Not wasting a second after realizing this, the demon beasts did not bother informing the other demon beasts. Instead choosing to use all of its strength to climb up the cliff towards the place where the weak Foundation Establishment Realm demon beast had disappeared just moments earlier. Knowing very well that it might lose this chance to escape in time if any of the more powerful demon beasts present discovered that there was a way out.
