Hearing Lu Xiangfei say this only made Tangyu even more certain that these people in black must be related to the mysterious force behind the Ghost Doctor.
This mysterious force was indeed terrifying, actually managing to infiltrate the surroundings of various Ancient Martial factions. There must be an earth-shattering conspiracy hidden within. A mere Ghost Doctor almost turned Donglin City upside down, and he was just a small pawn. Evidently, this Great Demon King mentioned by these men in black must be another pawn.
"Do you know who the Great Demon King is?" Tangyu asked.
Lu Xiangfei shook his head and said, "I've only heard this name mentioned once by these people, but we in the Lu Family have been searching without finding a shred of information about this Great Demon King."
