I Have a Soul-Telling Skill

I have a master and a beautiful mistress. On this day, the master disappeared and the mistress climbed up on my bedside. I held a mirror in my hand... Now, a frightened young face was vaguely reflected in the mirror. "My name is Zhang Nian, and I just want to survive tonight..." (Third person in the main text, first person in the extra story, supernatural horror text, with a bit of folklore...)
