Deep in the alleys of the old town of "Yanzhou City", Su Mo guards the "Mo Hen Ancient Books Restoration Museum" passed down by his grandfather. She has a special ability - when her fingertips touch the fragments of ancient books, she can sense the past memories behind the words, as if she can "dialogue" with the original owners of the ancient books.
