The moment that they heard the voice call out to them, Jasmine and Olivia whipped around with their weapons out and their guards up.
They had expected to see someone standing behind them up on the walkway above them where the voice had originated from, but there was no one there.
A few possibilities came to both of their minds.
One that there was a high-quality speaker hidden somewhere that could perfectly mimic a person's voice.
Two that the person was incredibly fast and had hidden themselves immediately after speaking out.
Or the third and most concerning option, was that they were using active camouflage to blend in with the surroundings and make themselves effectively invisible.
'There's nothing on my scanner, so, they either are out of range or have some way of concealing themselves. If it is active camouflage, then it has to be something top-of-the-line.'
