Strictly speaking, this wasn't Demonic Energy, but something... something...
Even Wang Jixuan found it hard to describe.
The suddenly appearing fluctuation was very faint. Calling it Demonic Energy didn't feel wicked enough, while calling it immortal energy was giving it too much credit. It was somewhat like the state before a plant or tree spirit attained the Dao, or perhaps some other type of power Wang Jixuan had never encountered.

Inside T.E.R's music studio;
Gao Huating, dressed in loungewear and playing an electronic keyboard, hummed a gentle melody.
The notes she played traveled through the broadcast towers installed throughout the fortress to the receiving devices on every floor.
Wang Jixuan had discovered long ago that T.E.R, this Underground Songstress, was actually cultivated by the fortress authorities to give the residents some encouragement.
Since fortress law explicitly prohibited entertainment activities in order to conserve the already scarce per-capita resources of the Fortress Era, she was an "underground" songstress.
Other than that, Gao Huating had displayed nothing unusual.
Yet the source of tonight's faint spiritual energy fluctuations was clearly Gao Huating.
Wang Jixuan returned to his room, lay on his bed, and closed his eyes to rest while carefully observing Gao Huating with his spiritual sense.
Strange. Her soul is unharmed, her body is healthy, and she's just an ordinary human.
A few minutes later, Gao Huating stopped singing, and the faint spiritual energy fluctuations quietly dissipated. In her sweet voice, she said:

"The next song was written for Black Storm, the hero of the fortress.
