Demons and evil spirits are afraid of light and fire, even electric lights.
This was one of the self-defense tips that Nurse Liu had initially imparted to Wang Yunxiao and the others.
Although they did not understand the principle behind it, as long as it worked, that was enough.
Third Master Ding had specifically chosen noon to entertain his guests, when the yang energy was at its strongest and the sun was blazing overhead. Under such conditions, no demon or evil spirit dared to show itself.
But one could not completely rule out exceptions.
For example, by draping themselves in clothes, or taking on a different skin...
Although Wang Yunxiao lacked experience, he had read plenty of novels in his last life and had anticipated such scenarios.
As expected, the opponent really did show up.
How dare he come? Don't you think the sunlight outside is a bit dazzling?
Of course, this wasn't important. One couldn't apply normal human logic to the behavior of a demon or evil spirit.
