Players can reserve the game on the museum's WeChat account and choose the single-role or three-role versions. They will act as ancient classic book protectors trying to find answers to puzzles with a good understanding of the hidden clues and achieve their goal of protecting the ancient books.

In the single-role version, the mission is to investigate a mysterious situation in the exhibition hall at midnight — the ancient book Shan Hai Jing turns its own pages.

If players choose the three-role version, a three-person group is necessary. Each player follows different parts of the storyline and completes different puzzles. Cooperation and competition will happen. Because a saboteur is hidden in the group, betrayals and cheating will shock the players. If the saboteur wins the game in the three-role version, players will have to face the "consequences" of failing to protect the ancient books.
