Nourishment
Despite his being afraid of another chunk of rock passing their way, he still stood up and grabbed hold of one of them and did his best not to let go. Yet, he was roughly shoved to the side.
However, before the being that pushed Elder Gu away was able to get far enough from them, he suddenly screamed in fright.
"Ah! What is this?!"
Their attention shifted to the scream and to their surprise, the black mist had surrounded the man, halting his movement.
They also heard screams coming from not far away, which were probably from those who left earlier. The man tried to get back to them but failed.
They could only watch how the impurities slowly squeezed his body, just allowing his head to be visible.
Splash!
It did not take long for his body to be shattered into blood and bone bits that immediately spread all over the place.
