You are pulled into a city.
Everyone here is lying - not by choice, by rule. If you tell the truth three times in a row, you will be flagged by the system. But the victory condition of the game is always: finding the truth.
Jiang Du, a former National Security Bureau interrogation expert, can hear the "noise" of lies the moment someone speaks. On the first day he entered the city, he thought he had the upper hand - until he discovered that there were forty-two people in the entire city just like him, all using different methods to detect lies.
Judgment Day occurs once a month, and the survival rate is less than one in ten. Those who are eliminated do not die and are sent to the observation room-where they can see who has lied, but every sentence returned will be automatically flipped between true and false by the system.
There are seven lines in the dungeon, and there is a truth hidden at the end of each one.
First sentence: Someone is watching. Sentence 6: The exit is above. The seventh sentence - no one found it until Jiang Du found that line of words hidden at the end of the twelfth floor.
And guarding behind that door was his twin brother who should have died twelve years ago.
The writing team is behind the mirror. The exit may not be a door, but a lie bigger than the entire city. Jiang Du holds the last subway card in his hand - he must choose between "going back to the past to save his brother" or "pushing away the future".
