"Ancestor Xu." The guard at the entrance greeted respectfully.
Ancestor Xu did not return the gesture and walked straight into the ancient building. This marked the difference between ancient and modern etiquette; in ancient times, it was expected for the subjects and subordinates to show respect, and it was impossible for the Emperor or master to return the gesture. In modern times, if someone greets you and you do not respond, it is considered impolite.
Lin Tian and several others followed Ancestor Xu inside in single file. Upon seeing the situation inside, Lin Tian frowned because there were quite a number of people seated within, each dressed in black robes, resembling Onmyoji, and encircling a circular altar.
