Does the subject want to ask "Is the seventh suspect Vivian the murderer?" ? Yes Vivian is the murderer in the play Murder of Suspect 7. Suspect number seven is a typical secret room killing method, but there are multiple tricks at the same time. In short, there are many details, and the reasoning process is brain-burning. Suspect 7 also has a double tail setting. When the player plays a normal ending, the game lasts about 4 to 5 hours, which is a relatively normal script to kill time. However, if the player asks some key questions in the recovery stage, or DM asks the player whether to open the "hidden ending" and the player agrees, then the game will enter the "hidden ending" stage, and the game duration will increase by about 1 hour.
