Mystery House

After his grandfather passed away, Gu Mingyuan inherited a bronze key and also inherited the Gu family's century-old mystery museum. People who enter the puzzle house must reason, vote, and choose. If they answer incorrectly, they will die. As old cases resurface, relatives turn against each other, and forces behind the scenes approach, he gradually discovers that what everyone is fighting for is not wealth, but a secret that can determine "who is right and who is wrong."
