He dragged the sofa back a bit and took a closer look before speaking, "This black mark should be the remnant of the Possession Spirit after it was killed."
Zhang Xiaomo looked up and asked, "Are you saying Xiong Suyuan killed the Possession Spirit that replicated him?"
"Quite likely," Yan Junze nodded, "both perished together."
After a pause, he looked around and said, "Did your teammate Xiong Suyuan's magnetic knife fall in the server room?"
Zhang Xiaomo recalled as she shook her head, "It seems... no, at that time, two people's magnetic knives were knocked away by that powerful Possession Spirit, one was mine, and the other was Yang Man's, just us two girls."
"He had a magnetic knife, so he had the chance to kill the Possession Spirit impersonating him," Yan Junze said, "Where's the magnetic knife? Look around here."
Zhang Xiaomo had already started looking underneath the sofa.
