"The Seventh Sigh of the Corridor of Time and Space" tells a story about the cycle of civilization and the struggle against despair. When the earth fell into the deathly "Great Silence", the "Heart of the Ark" space station became the last refuge of mankind. However, the activation of the global monitoring system "Guardian" unexpectedly awakened a transcendent existence called the "Monitor", which coldly announced that human civilization has reached the archive point and must undergo final evaluation. Failure will be completely "formatted" like the previous six iterations.
Captain Ella Costigan discovers that the Inquisitor is not an alien from outside, but a destructive creation created by the last civilization itself. Forced to sign the harsh "Guardian Agreement", technology is locked, thoughts are monitored, and humans become shackled probationers. But Ella did not give in. She led the crew to find loopholes in every dangerous "corridor maintenance" mission, using the complexity of the universe itself to deal with the absolute logic of the "Supervisor".
This is an intellectual game between doomed destruction and slim chance of survival. Can human beings use their shackles of wisdom to break this endless cycle and strive for a different future for themselves? Is the seventh civilization issuing a final sigh or a cry of resistance?
