''Ghosts often suffer from severe epidemics, and qi often fights at the beginning. This is a group of people who are dispatched to get rid of them and protect the country and the people. ''
This passage comes from a shabby ancient parchment book. It probably means that after a great epidemic, disaster, or war, ghosts will often appear and harm the people. At this time, our sect will send people to eliminate them, thereby ensuring the safety of the people.
