At this moment, the entire underground palace began to shake violently. Ding Fan immediately joined Ye Ningbing, obviously intending to protect her, since he was still unclear about what might happen next.
However, Ding Fan knew that the formation set by Li Zong was not likely a dangerous one, otherwise, he wouldn't have brought the two divine warrior girls here.

Ding Fan found himself benefiting from someone else's hard work.
Ding Fan estimated that even for Li Zong, setting up this formation was a highly complex task, especially since gathering that many Nascent Souls wasn't easy.
