Akin to a sonar, each Aether Energy Pulse that he had released revealed a little bit of the surroundings, thus allowing Aziel to draw up a map about the internal layout.
Hundreds of life signs appeared one after another in his range of scan. Unlike before, there were countless signals that responded to the energy pulses. Surprisingly, even to Aziel himself, almost everyone was at least at the Martial Warrior stage, with some Masters and even a singular Grandmaster residing somewhere deeper underground.
'Hmm... Interesting...' Aziel muttered inwardly as he calmed his energy circulation, ending the scanning process in the meantime.
'These people have some surprises... Even an old monster... What an unexpected surprise...' He mused, locking his spiritual sense on the approaching group.
