Yan Junze was still somewhat curious about the Spirit Cultivator, Yan Long.
He had met the man for the first time when he performed the "Great Rewind," of course, the latter did not recognize him.
But considering Yan Long was Cheng Jingting's teacher and Cheng Jingting, as a Spirit Cultivator, hoarded so many pots and jars at home and even raised a white-haired zombie, Junze wouldn't have discovered the cruel deeds Cheng was up to if he hadn't activated the Great Rewind to go back.
If even his disciple, Cheng Jingting, tinkered with so many spirit-nurturing items at home, then Yan Long, being the teacher, would likely have even more at his "secret lair."
Curious about everything related to Spirit Cultivators, and now that he was in Tianyi District and about to join other Exorcists to destroy Yan Long's den without much complexity and danger involved, Junze readily accepted the task.
