The Mass Burial Mound had existed for many years. Many civilian bodies, if not given proper burial, would ultimately end up buried here. As the years passed, nobody knew exactly how many bodies were buried within the Mass Burial Mound. Now, under the contamination of the Demon's Essence Blood, those bodies had transformed into Corpse Puppets and crawled out from their graves once more.
Fortunately, not all bodies can turn into Corpse Puppets. Only those relatively well-preserved can undergo this transformation; otherwise, the number of Corpse Puppets would grow substantially. Shen Changqing drew his long saber from its sheath and cut down a Corpse Puppet that lunged at him. Although the number of Corpse Puppets that had risen was considerable, it hadn't reached a level of despair. In my opinion, the powerful being who had sealed the Demon's Essence Blood here probably hadn't expected this place to become a Mass Burial Mound one day.
