Lu Bu'er paused upon hearing the term "Ghost Technique," clearly taken aback.
"You know?"
Lianhua glanced at his right hand.
As Lu Bu'er walked through the deep corridor, he shook his head.
Suddenly, Lianhua stopped, raised her hand, and placed it on the hard rock wall, giving it a firm push.
It turned out to be a hidden chamber—dusty cultures, broken wires, and fractured circuits. Terrifying skeletal remains were held within a massive cage, and atop an operating table lay a corpse.
The skeletal remains in the cage obviously belonged to some kind of Specter Fiends.
The body on the operating table was human, but it had a pair of bone wings sprouting from its back!
Unfortunately, there was no other information left behind, just discarded remnants of experiments from who knows how many years ago. But just from these two skeletons, some clues could be discerned.
