Corpse Puppet!
Zhao Yue's face showed confusion.
Cui Cheng patiently explained, "Corpse Puppets are the tools of Demon Evils. They kill people and then refine them into puppets. Those turned into Corpse Puppets can retain their memories from when they were alive, but they must obey their creator. To the untrained eye, it is very hard to distinguish Corpse Puppets from the living. Because Corpse Puppets are no longer living, they need to periodically consume fresh blood to prevent their flesh from decaying."
The Guiyuan Sword Sect, as one of the major sects in Guangyuan Prefecture, naturally possessed records concerning Corpse Puppets.
After finishing his explanation, Cui Cheng looked at Shen Changqing, understanding the latter's intention. "Lord Shen is worried that if news of the Corpse Puppets gets out, it will cause panic among the people!"
