At midnight, Xu Shu, who had recovered from his injuries, arrived as promised and revealed everything to you: "Young master, you possess extraordinary talents and are the son of our Lord. Now that you are involved, according to the rules, I can share this secret with you, but please keep it confidential. This is a secret of the Night Watchman Office."

"Here's the thing..."
Through Xu Shu's detailed explanation, you finally came to understand the deep secrets of this world.
It turned out that humans had always been plagued by 'yin ghosts' and rampant demons; human suffering was common, and the people, facing these elusive and undefeatable yin ghosts, had no ability to resist and were preyed upon like fish on a cutting board.
Fortunately, a thousand years ago, the night watchmen emerged in response to the call of duty, patrolling at midnight specifically to control yin ghosts.
