This energy fluctuation is extremely concealed, as if someone is deliberately controlling it, preventing the energy from dispersing.
If it weren't for the Energy Detector, Duke and his group wouldn't have discovered this peculiar energy fluctuation.
Normally, due to its subtlety, this energy fluctuation wouldn't have reached here and would be hard to detect.
But judging from the condition of the people in front, it's clear they've all noticed this energy fluctuation and are purposely waiting here for something.
Duke and the others decided to wait here as well, though they weren't sure what they were waiting for, they just followed suit, deciding to linger here regardless.
Just as the suffocating silence persisted for about half an hour, an unexpected change suddenly occurred.
BOOM!
A dull, thunderous noise, as if coming from the depths of the earth, resounded, causing the entire Blood-colored Plain to tremble.
