Lv Bai has already spent a week in this world.
During this period, although he only encountered supernatural occurrences three or four times, he was basically able to ascertain that using Yin Qi to track the supernatural was not always foolproof.
Some supernatural entities carried intense Yin Qi, like the Red-clothed Female Ghost, whose enormous Yin Qi could almost blanket the entire neighborhood.
However, some entities only carried pure Evil Qi, with no Yin Qi present, making it difficult to locate them using the Ghost-Searching Technique from Mao Mountain Daoist Technique.
Fortunately, Lv Bai wasn't in a rush, and he was willing to wait patiently if need be.
After all, once night falls, if there really is something supernatural, it would surely emerge to cause trouble.
...
As night fell.
Personnel from the action department began to gradually withdraw from the school, leaving only Captain Mao and the Lv Bao Bureau observer with Lv Bai.
