Aether Tower

Ning brought out a gun from his storage and pointed towards Reever.

"What? N—"

BANG! 

Ning shot without hesitation. Lisa cried out when she saw her husband get shot point-blank, but when she realized that the bullet never touched him, she was surprised.

"It's the same thing from back in the train," Lisa muttered under her breath, but Ning managed to hear it. 

"Yeah, it's a barrier. See, it works," Ning said and saw the shaking Reever. "Uhh… sorry about that. I probably should have given notice."

"Dear Alexis save me," Reever prayed. "Please don't do that again, brother Ning. I was about to have a heart attack."

"Yes, sorry," Ning said. "Right, so you know it works. Just keep the ring on your fingers at all times, and NEVER ignore the pulses. They will save your life."

"If this works… then it is really amazing, Ning," Lisa said. "How were you able to even invoke such a complicated item?"
